# 5.0SMDJ24CA-Q

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

5.0SMDJ24CA-Q from Liown, in a 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 (the CA suffix means bidirectional, so there is no cathode band); it is interchangeable with the other terminal and clamps transients of either polarity, with a 24.0V reverse stand-off voltage. |
| 2 | A2 | passive | Bidirectional TVS terminal (the CA suffix means bidirectional, so there is no cathode band); it is interchangeable with the other terminal and clamps transients of either polarity, with a 24.0V reverse stand-off voltage. |
