## Description

The BU100A is an NPN silicon transistor from STMicroelectronics, housed in a TO3 package. This component offers a maximum collector-emitter voltage (Vce) of 100V and a maximum collector current (Ic) of 10A. Its maximum collector power dissipation is rated at 30W.

Key electrical characteristics include a minimum forward current transfer ratio (hFE) of 40 and a maximum of 90, with a typical minimum hFE of 50. The transition frequency (fT) is a minimum of 100MHz. The operating temperature range is up to 150°C, with a maximum operating junction temperature of 200°C.

This transistor is suitable for applications requiring robust power handling and specific voltage and current ratings. The TO3 package is designed for through-hole mounting and typically requires appropriate heatsinking for thermal management.

Environmental compliance includes RoHS3 compliance, MSL 1, and REACH unaffected status, though these are noted as unverified.
