BC857BHZGT116

BC857BHZGT116 Description

The BC857BHZGT116 from ROHM Semiconductor is a PNP general-purpose transistor designed for automotive-grade applications, offering high reliability and performance in a compact SST3 (SOT-23-3) surface-mount package. With a collector-emitter breakdown voltage (Vce) of 45V and a maximum collector current (Ic) of 100mA, this transistor is optimized for low-power switching and amplification tasks. Its high transition frequency (250MHz) ensures efficient operation in high-speed circuits, while the low Vce saturation (650mV @ 5mA, 100mA) minimizes power loss. The device is RoHS3 compliant and REACH unaffected, making it suitable for environmentally conscious designs.

BC857BHZGT116 Features

• Automotive-Grade Reliability: Qualified for harsh environments with an operating temperature range up to 150°C (TJ).
• High DC Current Gain (hFE): 210 (min) @ 2mA, 5V, ensuring consistent amplification performance.
• Low Leakage Current: 15nA (ICBO) cutoff current enhances efficiency in battery-operated systems.
• Compact & Robust: SST3 (SOT-23-3) package with MSL1 (unlimited) moisture sensitivity, ideal for automated assembly.
• Low Saturation Voltage: 650mV @ 5mA, 100mA reduces power dissipation in switching applications.

BC857BHZGT116 Applications

• Automotive Electronics: Engine control units (ECUs), sensors, and infotainment systems due to its AEC-Q100 compliance (implied by automotive grade).
• Portable Devices: Power management and signal amplification in wearables and IoT devices.
• Industrial Control: Low-power switching in PLCs, relays, and motor drivers.
• Audio Amplification: Pre-amplifier stages and signal conditioning circuits leveraging its high hFE and low noise.
