ER304_AY_10001

PANJIT International · Fast Recovery / High Efficiency Diodes · DO-201AD

ER304_AY_10001 from PANJIT International, in a DO-201AD. 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 Cathode passive Cathode end, marked by the color band per the polarity note; the device is rated for 50 to 800 V recurrent peak reverse voltage depending on the ER3xx variant.
2 Anode passive Anode end, opposite the color-banded cathode; forward current is rated at 3 A average at 0.375 in (9.5 mm) lead length with TA = 55 °C.
