# SMCJ160CA

**YFW** · ESD And Surge Protection (TVS/ESD) · DO-214AB(SMC)

SMCJ160CA 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 | Terminal 1 of the 1500 W TVS, listed as Cathode in the pinning; the CA suffix part is bidirectional, so it clamps in both polarities (stand-off voltage 160 V, breakdown 178 V min to 197 V max at 1 mA, max clamp 259 V at 5.8 A). |
| 2 | Anode | passive | Terminal 2 of the 1500 W TVS, listed as Anode in the pinning; the CA suffix part is bidirectional, so it clamps in both polarities (stand-off voltage 160 V, breakdown 178 V min to 197 V max at 1 mA, max clamp 259 V at 5.8 A). |
