P6SMB27CA-AT from Brightking, in a SMB(DO-214AA). 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 bi-directional models), 23.10V reverse stand-off and 25.70~28.40V breakdown at 1mA for P6SMB27CA-AT, interchangeable with terminal 2. |
| 2 | A2 | passive | Bidirectional TVS terminal with no polarity, 37.5V max clamping at 16.3A peak pulse current (10/1000μs) for P6SMB27CA-AT, interchangeable with terminal 1. |
