TPSMB15A

Littelfuse · ESD And Surge Protection (TVS/ESD) · DO-214AA

TPSMB15A from Littelfuse, in a 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, identified by the color band on the package for unidirectional components; for the unidirectional TPSMB15A the reverse standoff voltage VR is 12.8 V with breakdown VBR of 14.3 V typical (12.8 V min to 15.8 V max at 1 mA) and maximum clamping voltage VC of 21.2 V at Ipp 28.8 A.
2 Anode passive Anode terminal of the unidirectional TVS, which conducts in the forward direction with a maximum forward voltage VF of 3.5 V at 50 A (VF < 3.5 V for parts with VBR < 300 V).
