LSRV04W-4AT1G

LRC · ESD And Surge Protection (TVS/ESD) · TSOP-6

LSRV04W-4AT1G from LRC, in a TSOP-6. 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/O1 passive ESD-protected channel 1 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V.
2 GND power_in Negative rail pin connected to system ground; positive ESD current is steered to it through the ESD diode and zener diode.
3 I/O2 passive ESD-protected channel 2 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V.
4 I/O4 passive ESD-protected channel 4 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V.
5 VREF power_in Positive rail pin of the diode array, with the integrated zener diode between it and GND clamping positive ESD voltage to the zener voltage.
6 I/O3 passive ESD-protected channel 3 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V.
