SA30A-E3

Vishay Intertech · TVS · DO-204AC

SA30A-E3 from Vishay Intertech, in a DO-204AC. 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 end of the uni-directional TVS (marked by the color band); VWM 30 V, VBR 33.3 V to 36.8 V at 1.0 mA, max clamping voltage 48.4 V at IPPM 10 A for SA30A.
2 A passive Anode end of the uni-directional TVS (no band); the SA30A is uni-directional (no CA suffix), so the pin is polarized and the device is rated 500 W peak pulse power on a 10/1000 μs waveform.
