2SAR574D3TL1

2SAR574D3TL1 Description

The 2SAR574D3TL1 from ROHM Semiconductor is a high-performance PNP bipolar junction transistor (BJT) designed for surface-mount applications. With a collector-emitter voltage (Vce) rating of 80V and a maximum collector current (Ic) of 2A, this transistor is optimized for power switching and amplification in demanding environments. Its low Vce saturation voltage (400mV @ 50mA, 1A) ensures efficient operation, while a high DC current gain (hFE ≥ 120 @ 100mA, 3V) provides excellent signal amplification. Packaged in a TO-252 (DPAK) form factor, it is suitable for automated assembly and high-volume production.
