# SMDJ26CA

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

SMDJ26CA from hongjiacheng, in a SMC(DO-214AB). 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 | Bidirectional TVS terminal 1 (interchangeable with terminal 2); 26V reverse stand-off, 28.9-31.9V breakdown at 1mA, 42.1V max clamping at 71.3A peak pulse current. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (interchangeable with terminal 1); no polarity, the cathode band on the outline drawing applies only to unidirectional parts. |
