T15B15AHM3

Vishay Intertech · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

T15B15AHM3 from Vishay Intertech, 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 Cathode passive Cathode terminal of the unidirectional TVS, marked by the color band; connects to the protected positive line, with VWM 12.8 V and VBR 14.3 V to 15.8 V at 1 mA for the T15B15A.
2 Anode passive Anode terminal of the unidirectional TVS, normally connected to ground/return, with maximum clamping voltage 21.2 V at IPPM 73.1 A for the T15B15A.
