|Name||TO-93 (Transistor Outline 93)|
|Pin Count||4 (typ)|
|Pitch||n/a (terminals and flying leads)|
|Solderability||Designed for hand soldering/screw lugs|
|Land Area||n/a (panel mount)|
|Height||49.5mm (exc. cable), 231mm (approx, cable fully extended)|
|Common Uses||High-power SCR’s|
Large panel mount package used for high-power SCR’s. Has good heat-sinking capabilities. Thread is 28.5mm in diameter, so fits 29-30mm hole. The metal case/thread is usually used as the anode, and the thick cable the cathode (there normally is a flying lead for the cathode also), along with a white flying lead for the gate.
