# PTVSHC1TF24VBH

**Shanghai Prisemi Elec** · TVS · SOD-123FL

PTVSHC1TF24VBH from Shanghai Prisemi Elec, in a SOD-123FL. 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 | One of the two terminals of the bidirectional TVS clamp, labeled Pin 1 on the SOD-123FL top view, protecting one I/O or power line with a 24 V peak reverse working voltage (VRWM) and 6500 W peak pulse power (tP = 8/20 µs) per line. |
| 2 | Pin 2 | passive | The second terminal of the bidirectional TVS clamp, labeled Pin 2 on the SOD-123FL top view, with the same per-line ratings as Pin 1 (24 V VRWM, 6500 W peak pulse power at tP = 8/20 µs). |
