Axial diode

An axial leaded diode with formed leads, lying on the board or standing up. The package outlines are Vishay's: DO-35 (DO-204AH, a glass body), DO-41 (DO-204AL), DO-15 (DO-204AC), DO-201AD and P600, each from a Vishay data sheet.

Lead 1, the cathode at the band, is at the origin. Lead 2, the anode, is at +X by pitch, and both leads go down through the board, tail below it.

Horizontal. The body lies on the board along X, centred between the leads, with its band toward lead 1.
Vertical. The body stands on the board. With up = "anode" it stands over lead 1, and with up = "cathode" over lead 2. The top lead clears the body's top, turns over and comes back down at the other hole.

Package	Body Ø	Body length	Lead Ø	Sheet
DO-35 (DO-204AH)	1.5–1.75	3.4 max	0.55 max	1N4148
DO-41 (DO-204AL)	2.0–2.7	4.1–5.2	0.71–0.86	1N4001
DO-15 (DO-204AC)	3.3–3.5	6.15–6.55	0.71–0.86	P6KE6.8A
DO-201AD	4.8–5.3	7.2–9.5	1.22–1.32	1N5400
P600	8.6–9.1	8.6–9.1	1.22–1.32	P600A

The part uses the middle of each range. Where the sheet gives only a maximum (DO-35's length and lead), it uses that value.

The moulded packages carry a colour band at the cathode end ("color band denotes cathode end"). The leads are 25.4 min long before forming.

Proportions, for looks only. The sheets draw the body but dimension only its diameter and length:

The body's end edges are rounded by 0.25 x the radius, or 0.45 x on the DO-35's glass.
The cathode band is 0.18 x the length wide, starting at the cathode end's rounding.
The leads are bent with a radius of one lead diameter. On a vertical part, the top lead rises 2 lead diameters + 1 above the body before it turns.
Materials are for looks and a rough mass:
- DO-35 is borosilicate glass in amber, with a black band.
- The moulded packages are epoxy. Nylon (PA6) is the nearest in the list. They are black with a light band.
- The leads are tin-plated copper.

Catalogue models

The catalogue's D_<package>_P<pitch>mm_<Horizontal|Vertical_AnodeUp|Vertical_CathodeUp> models name a JEDEC package (or the P600 / R-6 case) and a pitch, and 29 of them map.

On the reference models, lead 1 is at the origin. A horizontal body lies between the leads. A vertical body stands over lead 1 when the anode is up and over lead 2 when the cathode is up. The pitch is the named one.

Measured on six reference models (body Ø x length, lead Ø):

Model	Measured	Vishay's sheet
DO-41 P7.62 horizontal	2.72 x 5.2, 0.80	2.0–2.7 x 4.1–5.2, 0.71–0.86
DO-35 P7.62 horizontal	2.02 x 4.0, 0.50	1.5–1.75 x 3.4 max, 0.55 max
DO-15 P10.16 horizontal	3.62 x 7.6, 0.90	3.3–3.5 x 6.15–6.55, 0.71–0.86
DO-201AD P12.70 horizontal	5.22 x 9.5, 1.30	4.8–5.3 x 7.2–9.5, 1.22–1.32
P600 P12.70 horizontal	9.12 x 9.1, 1.30	8.6–9.1 x 8.6–9.1, 1.22–1.32
DO-41 P2.54 vertical, anode up / cathode up	2.72 x 5.2	as above

The models are drawn at or beyond the largest body that each package allows. The DO-35 and DO-15 models are larger than Vishay's maximums: the DO-35 by 0.27 in diameter and 0.6 in length, and the DO-15 by 0.12 in diameter and 1.05 in length.

The names name the package, so they map to Vishay's outline of that package, and the pitch and lead order are as named. The bodies lie on the board, where the models raise them about 0.6.

Left as "no table read yet" until a sheet is read: 5KP, 5KPW, 5W, A-405, DO-201, DO-201AE, DO-27, DO-34, T-1, DO-247 and the bridge rectifiers.

Axial leaded diode with formed leads, lying on the board or standing up: Vishay's DO-35 (DO-204AH, glass), DO-41 (DO-204AL), DO-15 (DO-204AC), DO-201AD and P600 package outlines, from Vishay's data sheets. Lead 1 (the cathode, by the band) at the origin, lead 2 along +X. See the README.

Axial diode

Lead 1, the cathode at the band, is at the origin. Lead 2, the anode, is at +X by pitch, and both leads go down through the board, tail below it.

Horizontal. The body lies on the board along X, centred between the leads, with its band toward lead 1.
Vertical. The body stands on the board. With up = "anode" it stands over lead 1, and with up = "cathode" over lead 2. The top lead clears the body's top, turns over and comes back down at the other hole.

Package	Body Ø	Body length	Lead Ø	Sheet
DO-35 (DO-204AH)	1.5–1.75	3.4 max	0.55 max	1N4148
DO-41 (DO-204AL)	2.0–2.7	4.1–5.2	0.71–0.86	1N4001
DO-15 (DO-204AC)	3.3–3.5	6.15–6.55	0.71–0.86	P6KE6.8A
DO-201AD	4.8–5.3	7.2–9.5	1.22–1.32	1N5400
P600	8.6–9.1	8.6–9.1	1.22–1.32	P600A

The part uses the middle of each range. Where the sheet gives only a maximum (DO-35's length and lead), it uses that value.

The moulded packages carry a colour band at the cathode end ("color band denotes cathode end"). The leads are 25.4 min long before forming.

Proportions, for looks only. The sheets draw the body but dimension only its diameter and length:

The body's end edges are rounded by 0.25 x the radius, or 0.45 x on the DO-35's glass.
The cathode band is 0.18 x the length wide, starting at the cathode end's rounding.
The leads are bent with a radius of one lead diameter. On a vertical part, the top lead rises 2 lead diameters + 1 above the body before it turns.
Materials are for looks and a rough mass:
- DO-35 is borosilicate glass in amber, with a black band.
- The moulded packages are epoxy. Nylon (PA6) is the nearest in the list. They are black with a light band.
- The leads are tin-plated copper.

Catalogue models

The catalogue's D_<package>_P<pitch>mm_<Horizontal|Vertical_AnodeUp|Vertical_CathodeUp> models name a JEDEC package (or the P600 / R-6 case) and a pitch, and 29 of them map.

Measured on six reference models (body Ø x length, lead Ø):

Model	Measured	Vishay's sheet
DO-41 P7.62 horizontal	2.72 x 5.2, 0.80	2.0–2.7 x 4.1–5.2, 0.71–0.86
DO-35 P7.62 horizontal	2.02 x 4.0, 0.50	1.5–1.75 x 3.4 max, 0.55 max
DO-15 P10.16 horizontal	3.62 x 7.6, 0.90	3.3–3.5 x 6.15–6.55, 0.71–0.86
DO-201AD P12.70 horizontal	5.22 x 9.5, 1.30	4.8–5.3 x 7.2–9.5, 1.22–1.32
P600 P12.70 horizontal	9.12 x 9.1, 1.30	8.6–9.1 x 8.6–9.1, 1.22–1.32
DO-41 P2.54 vertical, anode up / cathode up	2.72 x 5.2	as above

The names name the package, so they map to Vishay's outline of that package, and the pitch and lead order are as named. The bodies lie on the board, where the models raise them about 0.6.

Left as "no table read yet" until a sheet is read: 5KP, 5KPW, 5W, A-405, DO-201, DO-201AE, DO-27, DO-34, T-1, DO-247 and the bridge rectifiers.
