NSVBC857BTT1G Description

The NSVBC857BTT1G from onsemi is a high-performance PNP bipolar junction transistor (BJT) designed for low-power, high-frequency applications. Packaged in a compact SC-75 (SOT-416) surface-mount form factor, it offers a 45V collector-emitter breakdown voltage (V_CEO) and a 100mA maximum collector current (I_C), making it ideal for signal amplification and switching in space-constrained designs. With a transition frequency (f_T) of 100MHz, it ensures efficient operation in high-speed circuits. The device is RoHS3 compliant, REACH unaffected, and features a moisture sensitivity level (MSL) of 1, ensuring reliability in diverse environmental conditions.

NSVBC857BTT1G Features

• Low V_CE(sat): Only 650mV at 5mA base current (I_B) and 100mA collector current, minimizing power loss in switching applications.
• High DC Current Gain (h_FE): 220 (min) at 2mA I_C and 5V V_CE, ensuring strong signal amplification.
• Ultra-Low Leakage Current: 15nA (max) collector cutoff current (I_CBO) enhances efficiency in precision circuits.
• Compact & Reliable: SC-75 package (1.2mm x 0.8mm) saves PCB space while maintaining 200mW max power dissipation.
• Wide Operating Range: Suitable for -55°C to +150°C environments, backed by onsemi's quality assurance.
