SRV05-4HTG-D

Littelfuse · ESD And Surge Protection (TVS/ESD) · SOT-23-6

SRV05-4HTG-D from Littelfuse, in a SOT-23-6. 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/O 1 passive ESD/surge-protected I/O channel 1 with rail-to-rail steering diodes, about 1pF typical capacitance to GND.
2 GND power_in Ground reference for the TVS array; I/O pins are clamped to GND (breakdown 6V min at 1mA, 8.5V max).
3 I/O 2 passive ESD/surge-protected I/O channel 2 with rail-to-rail steering diodes, about 1pF typical capacitance to GND.
4 I/O 3 passive ESD/surge-protected I/O channel 3 with rail-to-rail steering diodes, about 1pF typical capacitance to GND.
5 VCC power_in Positive rail of the steering diodes, connected to the supply or protected rail; reverse standoff voltage is 6V.
6 I/O 4 passive ESD/surge-protected I/O channel 4 with rail-to-rail steering diodes, about 1pF typical capacitance to GND.
