# MMBD914-JSM

**JSMSEMI** · Switching Diodes · SOT-23-3

MMBD914-JSM from JSMSEMI, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the single switching diode (VRRM/VR 100 V, IO 300 mA, IFSM 2 A at t=8.3ms), per the simplified outline between pins 1 and 3. |
| 2 | NC | unconnected | Pin 2 is not connected to the diode in the simplified outline, which shows the diode only between pins 1 and 3. |
| 3 | K | passive | Cathode of the single switching diode (VRRM/VR 100 V, IO 300 mA, IFSM 2 A at t=8.3ms), per the simplified outline between pins 3 and 1. |
