# SMAJ45A

**AnBon** · TVS · SMA(DO-214AC)

SMAJ45A from AnBon, in a SMA(DO-214AC). 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 of the uni-directional TVS, marked by the cathode band on the package; for SMAJ45A the reverse stand-off voltage V_RWM is 45 V and the maximum clamping voltage is 72.7 V at Ipp 5.5 A. |
| 2 | Anode | passive | Anode of the uni-directional TVS (pin 2 per the datasheet pinning table); the device is rated for 400 W peak pulse power at 10/1000 µs waveform. |

## CAD (KiCad official)

- Symbol: `SMAJ45A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `smaj45a-etched.step` / `smaj45a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smaj45a.step` / `smaj45a.glb` are the bare package body.
