SMCJ90A
YFW · ESD And Surge Protection (TVS/ESD) · DO-214AB(SMC)
SMCJ90A from YFW, in a DO-214AB(SMC). 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 | Cathode | passive | Cathode terminal of the SMCJ90A unidirectional TVS diode, which is the polarity-marked end per the datasheet pinning (1.Cathode), and the device is rated for 1500 W peak pulse power on a 10/1000 µs waveform. |
| 2 | Anode | passive | Anode terminal of the SMCJ90A unidirectional TVS diode, paired with pin 1 Cathode per the datasheet pinning (2.Anode), and the device is rated for a maximum operating junction and storage temperature range of -65 to +150 °C. |
