2SAR553P5T100

2SAR553P5T100 Description

The 2SAR553P5T100 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 50V and a maximum collector current (Ic) of 2A, this transistor is optimized for power-efficient switching and amplification in compact electronic circuits. Its low Vce saturation voltage (400mV @ 35mA, 700mA) ensures minimal power loss, while a transition frequency (fT) of 320MHz enables high-speed operation. Packaged in MPT3 (Tape & Reel), it is ideal for automated assembly processes.

2SAR553P5T100 Features

• High Current Handling: Supports up to 2A continuous collector current, making it suitable for power management tasks.
• Low Saturation Voltage: 400mV @ 35mA, 700mA reduces energy dissipation in switching applications.
• High DC Current Gain (hFE): Min 180 @ 50mA, 2V ensures efficient signal amplification.
• Wide Operating Temperature: Up to 150°C (TJ) for reliable performance in harsh environments.
• Compact & RoHS-Compliant: MPT3 package (3-pin) with ROHS3 compliance meets modern environmental standards.
• Low Leakage Current: 1µA (ICBO) cutoff current enhances power efficiency in standby modes.

2SAR553P5T100 Applications

• Power Management: Ideal for DC-DC converters, voltage regulators, and load switches due to its low saturation voltage.
