TPMMBZ27VCLT1G

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23

TPMMBZ27VCLT1G from TECH PUBLIC, in a SOT-23. 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 Anode of the first uni-directional TVS diode (protected line 1), 24V max reverse working voltage, 27V min breakdown at 1mA.
2 A2 passive Anode of the second uni-directional TVS diode (protected line 2), 24V max reverse working voltage, 27V min breakdown at 1mA.
3 K passive Common cathode of both TVS diodes (top lead in the SOT23 diagram), clamping at 50V max at Ipp=5A (8/20us).
