BCX53-16

BCX53-16 Description

The BCX53-16 from Diotec Semiconductor is a high-performance PNP bipolar junction transistor (BJT) designed for surface-mount applications. With a collector-emitter breakdown voltage (Vce) of 80V and a maximum collector current (Ic) of 1A, this transistor is optimized for low-voltage, high-current switching and amplification in compact electronic circuits. Its low saturation voltage (500mV @ 50mA, 500mA) ensures efficient power handling, while a minimum DC current gain (hFE) of 100 @ 150mA, 2V guarantees stable signal amplification. The 50MHz transition frequency makes it suitable for moderate-speed switching applications. Packaged in bulk format, the BCX53-16 is ideal for automated assembly processes.
