BST363A054U

UMW · ESD And Surge Protection (TVS/ESD) · SOT-363

BST363A054U from UMW, in a SOT-363. 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 I/O bidirectional Protected data/power line that carries the ESD and surge protection, rated to IEC 61000-4-2 ±15kV contact and ±20kV air.
2 GND power_in Ground reference for the protection clamps; the datasheet gives the I/O-to-GND capacitance measured at VR=0V, f=1MHz.
3 I/O bidirectional Protected data/power line that carries the ESD and surge protection, rated to IEC 61000-4-2 ±15kV contact and ±20kV air.
4 I/O bidirectional Protected data/power line that carries the ESD and surge protection, rated to IEC 61000-4-2 ±15kV contact and ±20kV air.
5 VCC power_in Supply pin of the device; the datasheet specifies a working peak reverse voltage VRWM of 5V for the protected line.
6 I/O bidirectional Protected data/power line that carries the ESD and surge protection, rated to IEC 61000-4-2 ±15kV contact and ±20kV air.
