# RESD1CANFHT116

**ROHM Semicon** · ESD And Surge Protection (TVS/ESD) · SOT-23

RESD1CANFHT116 from ROHM Semicon, in a SOT-23. 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 | 1 | passive | Anode of the first TVS diode (VRWM 24 V, VBR 26.2 to 32 V at 1 mA), connected through that diode to common pin 3. |
| 2 | 2 | passive | Anode of the second TVS diode (VRWM 24 V, VBR 26.2 to 32 V at 1 mA), connected through that diode to common pin 3. |
| 3 | 3 | passive | Common terminal joining both TVS diodes, with a maximum clamping voltage of 44 V at Ipp=8 A (8/20us). |
