# TPE2462BC3

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-323

TPE2462BC3 from TECH PUBLIC, in a SOT-323. 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 | PIN 1 | passive | Protected CAN bus line 1 with a TVS diode to common pin 3; reverse working voltage 24V max, ESD ±30kV air/contact. |
| 2 | PIN 2 | passive | Protected CAN bus line 2 with a TVS diode to common pin 3; reverse working voltage 24V max, ESD ±30kV air/contact. |
| 3 | PIN 3 | passive | Common node of the two TVS diodes (the schematic joins both diodes here); the datasheet does not name it as ground. |
