# SMCJ58CAHE3_A

**Vishay Intertech** · TVS · DO-214AB(SMCJ)

SMCJ58CAHE3_A from Vishay Intertech, in a DO-214AB(SMCJ). 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 | A1 | passive | Bi-directional terminal 1 of the CA-suffix device, which has no cathode band, and its electrical characteristics apply in both directions with VWM 58 V and VBR 64.4 V to 71.2 V. |
| 2 | A2 | passive | Bi-directional terminal 2 of the CA-suffix device, which has no cathode band, and its electrical characteristics apply in both directions with VWM 58 V and a maximum clamping voltage of 93.6 V at IPPM 16.0 A. |
