ATV04A400JB-HF from Comchip, 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 | A1 | passive | Bidirectional TVS terminal with no polarity (no cathode band on bipolar parts); device has 40.0V working peak reverse voltage (VRWM), 44.40-49.10V breakdown at 1mA, and 64.5V maximum clamping at 6.20A IPP. |
| 2 | A2 | passive | Bidirectional TVS terminal interchangeable with the other terminal; device rated 400W peak pulse power on a 10/1000μs waveform with 1.0µA maximum reverse leakage at VRWM. |
