Overview

The STMicroelectronics BD136 is a versatile PNP bipolar junction transistor designed for general-purpose amplification and switching applications. Its key operational characteristic lies in its moderate current handling capability (up to 1.5A continuous collector current) and a respectable VCEO of 45V, making it suitable for driving medium-power loads. A critical design consideration when utilizing the BD136 is managing its thermal dissipation; with a Pd of 1.25W, careful heatsinking is paramount in higher ambient temperature environments to prevent junction overstress and ensure long-term reliability, a common trade-off in cost-effective through-hole components.
