PTVSHC3D4V5B-MS

MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOD-323

PTVSHC3D4V5B-MS from MSKSEMI, in a SOD-323. 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 Pin1 passive Pin1 is one terminal of the TVS line protected by the device, with reverse working voltage VRWM of 4.5 V and breakdown voltage VBR of 4.6 V min to 6.1 V max at It = 1 mA, measured Pin1 to Pin2.
2 Pin2 passive Pin2 is the other terminal of the protected line, forming the Pin1 to Pin2 path for the stated clamping voltages (7.5 V to 16 V across 20 A to 130 A at tP = 8/20 µs) and the 2 µA maximum reverse leakage at VRWM = 4.5 V.
