TPCDSOT23-SRV05-4

TECH PUBLIC · ESD Protection Devices · SOT-23-6

TPCDSOT23-SRV05-4 from TECH PUBLIC, 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/O1 passive Protected data line I/O (Note 1 lists pins 1, 3, 4 and 6 as I/O); 5V reverse working voltage max, 0.35 pF typical between I/O pins.
2 GND power_in Ground reference of the TVS array, the return to which the I/O pins are tested (I/O pin to ground).
3 I/O2 passive Protected data line I/O (Note 1 lists pins 1, 3, 4 and 6 as I/O); 5V reverse working voltage max, ±25 kV air/contact ESD per IEC 61000-4-2.
4 I/O3 passive Protected data line I/O (Note 1 lists pins 1, 3, 4 and 6 as I/O); 20 V max clamping voltage at IPP = 3 A (8x20 µs).
5 VCC power_in Power line connection at the top of the steering diodes and the center TVS diode; the datasheet says the array protects one power line in addition to 4 data lines.
6 I/O4 passive Protected data line I/O (Note 1 lists pins 1, 3, 4 and 6 as I/O); 0.8 pF max junction capacitance to ground.
