SA16A

SUNMATE Elec · ESD And Surge Protection (TVS/ESD) · DO-15

SA16A from SUNMATE 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, the end marked with the cathode band on the unidirectional SA16A (RWM 16 V, VBR 17.8-20.5 V at 1.0 mA, VC 26.0 V at IPP 19.6 A).
2 A passive Anode, the axial lead opposite the cathode band; the SA16A unidirectional device is rated 500 W peak pulse power (10/1000µs) with IR 3.0 µA at stand-off voltage.
