# P6KE200A

**MDD Microdiode Semiconductor** · ESD And Surge Protection (TVS/ESD) · DO-15

P6KE200A from MDD Microdiode Semiconductor, 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, the end marked with the polarity band on the body; for the unidirectional P6KE200A it goes to the positive side, with VWM 171 V, V(BR) 190-210 V at 1.0 mA and maximum clamping voltage 274 V at IPPM 2.2 A. |
| 2 | A | passive | Anode, the end without the polarity band; it conducts forward (VF max 3.5 V at 50 A for V(BR) up to 200 V) and carries the 600 W minimum peak pulse power (10/1000µs). |
