STTH3R02

STMicroelectronics · Diodes - Fast Recovery Rectifiers · DO-201AD

STTH3R02 from STMicroelectronics, 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	K	passive	Cathode of the ultrafast diode (VRRM 200 V, IF(AV) 3 A); the datasheet marks A and K on the package drawing without printed pin numbers.
2	A	passive	Anode of the ultrafast diode (VRRM 200 V, IF(AV) 3 A); the datasheet marks A and K on the package drawing without printed pin numbers.
