# SRV05-4.TCT-JSM

**JSMSEMI** · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

SRV05-4.TCT-JSM from JSMSEMI, in a SOT-23-6L. 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 I/O line (one of four) with typical 0.3pF line-to-line capacitance, steered by diodes to the Vcc/GND pins, rated 5V working voltage. |
| 2 | GND | power_in | Ground reference pin connected to the anode of the central TVS diode; I/O pins are specified against GND with VRWM 5.0V max and IEC 61000-4-2 ESD of ±27kV air and ±16kV contact. |
| 3 | I/O2 | passive | ESD-protected I/O line (one of four) with typical 0.3pF line-to-line capacitance, steered by diodes to the Vcc/GND pins, rated 5V working voltage. |
| 4 | I/O3 | passive | ESD-protected I/O line (one of four) with typical 0.3pF line-to-line capacitance, steered by diodes to the Vcc/GND pins, rated 5V working voltage. |
| 5 | VCC | power_in | Vcc line protected by the central TVS diode and connected to the cathode of the steering diodes, as shown in the pin configuration; the datasheet states it protects one Vcc line. |
| 6 | I/O4 | passive | ESD-protected I/O line (one of four) with typical 0.3pF line-to-line capacitance, steered by diodes to the Vcc/GND pins, rated 5V working voltage. |
