MPSA05RA

MPSA05RA Description

The MPSA05RA from onsemi is an NPN bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. Packaged in a TO-92-3 through-hole format and supplied in Tape & Reel (TR), it offers a robust solution for low-to-medium power circuits. With a collector-emitter voltage (Vce) rating of 60V and a maximum collector current (Ic) of 500mA, this transistor balances performance and efficiency. Its transition frequency of 100MHz ensures suitability for high-speed switching, while a DC current gain (hFE) of at least 100 @ 100mA, 1V guarantees reliable amplification.

MPSA05RA Features

• High Voltage Tolerance: 60V Vce breakdown voltage for robust operation in varied conditions.
