Description
The BD140 is a popular and reliable PNP power transistor designed for medium-power switching and amplification applications. Capable of handling a continuous collector current of 1.5A, this transistor is an excellent choice for driving heavier loads, such as small motors, relays, and power-hungry indicator systems that exceed the capacity of standard small-signal transistors.
With a DC current gain (hFE) range of 40 to 250, the BD140 provides consistent performance across various circuit configurations. Its robust design, featuring an 80V Collector-Emitter voltage rating and a maximum junction temperature of 150°C, ensures stable operation under challenging conditions. This pack of 10 units provides a cost-effective, high-value solution for your prototyping, R&D, or professional repair and maintenance inventory.
