PSR05-LF-T7

UMW · ESD And Surge Protection (TVS/ESD) · SOT-143

PSR05-LF-T7 from UMW, in a SOT-143. 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 GND power_in Ground reference pin for the TVS diode array; the datasheet gives ESD protection of ±30 kV (IEC 61000-4-2) and clamping performance referenced to this pin.
2 I/O1 bidirectional Protected signal line 1 of the low-capacitance TVS array, with junction capacitance of 5 to 10 pF between I/O pins and ground at VR=0 V, 1 MHz.
3 I/O2 bidirectional Protected signal line 2 of the low-capacitance TVS array, with junction capacitance between I/O pins listed at 3 to 5 pF at VR=0 V, 1 MHz.
4 VDD power_in Supply-side pin of the TVS array, rated for a 5 V operating voltage per the datasheet features list.
