# 30KPA90CA

**Littelfuse** · ESD And Surge Protection (TVS/ESD) · P600

30KPA90CA from Littelfuse, in a P600. 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 | A1 | passive | Bidirectional TVS terminal (axial lead, no polarity, no cathode band on CA parts); 90V reverse standoff VR, 100.50-110.55V breakdown at 5mA, 146.4V max clamping at 207.0A Ipp. |
| 2 | A2 | passive | Bidirectional TVS terminal (axial lead, interchangeable with the other lead); 30kW peak pulse power at 10/1000µs, max 2µA leakage at VR (the datasheet says the IR limit is doubled only for VRWM of 60V and below). |
