TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-353-5
TPESD5V0J4 from TECH PUBLIC, in a SOT-353-5. 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 | TVS protected I/O line 1, steered by diodes to the common center node (pin 2); reverse working voltage 5V max, 100nA max leakage at VRWM=5V. |
| 2 | GND | power_in | Common ground node of the TVS array, connected to the steering diodes and center clamp; I/O to GND capacitance 60pF typ, 90pF max at VR=0V, f=1MHz. |
| 3 | I/O2 | passive | TVS protected I/O line 2, steered by diodes to the common center node (pin 2); ESD rated ±30kV air and contact per IEC61000-4-2. |
| 4 | I/O3 | passive | TVS protected I/O line 3, steered by diodes to the common center node (pin 2); clamping voltage 11V max at IPP=4.5A (8/20µs). |
| 5 | I/O4 | passive | TVS protected I/O line 4, steered by diodes to the common center node (pin 2); clamping voltage 14V max at IPP=10A (8/20µs). |
