BD135-16 Description

Short technical summary and product information.

The BD135-16 is an NPN bipolar junction transistor manufactured by STMicroelectronics. It is designed for general-purpose switching and amplification applications. The transistor features a collector-emitter voltage (Vce) of 45V and a collector current (Ic) of 1.5A, with a power dissipation of 1.25W. It offers a minimum DC current gain (hFE) of 40 at 150mA collector current and 2V Vce, and a maximum Vce saturation voltage of 500mV at 500mA collector current and 50mA base current.

 

The device is housed in a SOT-32 package, which is also known as TO-225AA or TO-126-3, and is designed for through-hole mounting. The operating junction temperature range is up to 150°C. The BD135-16 is RoHS3 compliant and has an MSL rating of 1 (unlimited).

 

This transistor is suitable for a variety of low-power switching and linear applications, including driver stages, signal amplification, and voltage regulation circuits. Its robust electrical characteristics make it a reliable choice for general-purpose use.
