# P6KE170A

**RUILON Shenzhen Ruilongyuan Elec** · ESD And Surge Protection (TVS/ESD) · DO-15

P6KE170A from RUILON Shenzhen Ruilongyuan Elec, in a DO-15. 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 | K | passive | Cathode (marked with the cathode band on unidirectional parts), which connects to the protected positive line. For the P6KE170A the reverse stand-off voltage is 145 V, the breakdown voltage is 162 V to 179 V at 1 mA, and the maximum clamping voltage is 234 V at 2.60 A peak pulse current (10/1000µs). |
| 2 | A | passive | Anode, which connects to the return or ground side. Forward voltage is 3.5/6.5 V at 25 A and peak forward surge current is 100 A (8.3 ms half sine, unidirectional only). |
