Datasheet · from vishay.com
Substitutes same kind
Diodes of the same kind; for clipping, the forward drop is what you hear. The figures are read off each part's datasheet (this one's from page 1), typical where the sheet gives a typical value, otherwise the maximum. Closest first; the last column says what differs. A different part can change the sound, and a circuit may lean on one particular figure, so read the build document's notes before you swap.
This part
| Part | Vf | If max | Vr | trr | Cj | Package | Boards |
|---|---|---|---|---|---|---|---|
| BAT41 | 0.4 V @ 1 mA | 0.1 A | 100 V | 2 pF | DO-35 | 113 |
About 0.4 V at 1 mA, close to a germanium clipping drop with far lower leakage.
Alternatives
| Part | Vf | If max | Vr | trr | Cj | Package | Boards | Differs |
|---|---|---|---|---|---|---|---|---|
| 1N5711 | 0.41 V @ 1 mA | 0.033 A | 50 V | 2 pF | DO-35 | 4 | Low-capacitance 70 V Schottky with very low leakage, but only 33 mA average current. | |
| BAT46 | 0.25 V @ 0.1 mA | 0.15 A | 100 V | 10 pF | DO-35 | 115 | Low-drop Schottky clipper, about 0.25 V at 0.1 mA, with a 100 V rating. | |
| BAT43 | 0.33 V @ 2 mA | 0.2 A | 30 V | 5 ns | 7 pF | DO-35 | 2 | Same die as the BAT42 but specified at low current: 0.26-0.33 V at 2 mA. |
| BAT42 | 0.4 V @ 10 mA | 0.2 A | 30 V | 5 ns | 7 pF | DO-35 | 18 | 30 V Schottky in glass, about 0.4 V at 10 mA. |
| BAT85S | 0.24 V @ 0.1 mA | 0.2 A | 30 V | 5 ns | 10 pF | DO-35 | 2 | Very low-drop glass Schottky: 0.24 V at 0.1 mA, 0.32 V at 1 mA. |
| 1N60P | 0.24 V @ 1 mA | 0.05 A | 45 V | 1 ns | 6 pF | DO-35 | 32 | lower forward drop. This 1N60P is a Schottky, not a germanium point-contact diode, though it is often sold as a germanium substitute. |
| 1N5819 | 0.6 V @ 1000 mA | 1 A | 40 V | 110 pF | DO-41 | 61 | DO-41 | |
| 1N5818 | 0.55 V @ 1000 mA | 1 A | 30 V | 125 pF | DO-41 | 42 | DO-41 | |
| B5817WS-TP | 0.45 V @ 1000 mA | 1 A | 20 V | 50 ns | 80 pF | SOD-323 | 2 | 20 V reverse; SOD-323. Surface-mount 1N5817 equivalent for polarity protection; leakage is high (up to 200 µA at 20 V). |
| 1N5817 | 0.45 V @ 1000 mA | 1 A | 20 V | 125 pF | DO-41 | 4236 | 20 V reverse; DO-41. Vf is specified only at 1 A and above, so the sheet says nothing about the low clipping knee. |
