MMBD1204 from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of D1; forward voltage 550-600 mV at IF = 1 mA, max repetitive reverse voltage VRRM = 100 V, max average forward current IF(AV) = 200 mA. |
| 2 | A2 | passive | Anode of D2; forward voltage 550-600 mV at IF = 1 mA, max repetitive reverse voltage VRRM = 100 V, max average forward current IF(AV) = 200 mA. |
| 3 | K | passive | Common cathode of D1 and D2; reverse recovery time trr = 4.0 ns max (IF = IR = 10 mA, IIR = 1 mA, RL = 100 Ω), total capacitance CT = 2.0 pF max at VR = 0 V, f = 1 MHz. |
