STTH1L06

STMicroelectronics · Diodes - General Purpose · DO-41

STTH1L06 from STMicroelectronics, in a DO-41. 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, identified by the band on the DO-41 package body; the device blocks up to VRRM = 600 V in reverse.
2 A passive Anode of the diode, conducting average forward current IF(AV) = 1 A (Tc = 120 °C, δ = 0.5) with VF max 1.05 V at 150 °C.
