2SB772-Y-BP

Single Bipolar Transistors Overview

The MCC 2SB772-Y-BP is a PNP silicon plastic-encapsulated transistor designed for low voltage and high current applications. It features a collector-emitter breakdown voltage of 30V, a collector-base voltage of 40V, and a continuous collector current of 3.0A. The device supports up to 1.25W power dissipation with an operating junction temperature range from -55°C to +150°C. The 'Y' suffix indicates a DC current gain (hFE) classification of 160 to 320 at IC=1.0Adc and VCE=2.0Vdc. It utilizes a TO-92 package with Pin 1 as Emitter, Pin 2 as Collector, and Pin 3 as Base.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix '-BP' confirms bulk packaging containing 1Kpcs per box. Ensure the 'Y' designation matches the required hFE binning of 160-320 for your circuit design. Confirm RoHS compliance status if halogen-free requirements are necessary, as standard parts may not include the '-HF' suffix. Purchase only from authorized distributors to guarantee genuine components and traceability.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 3A current handling and 30V breakdown is required. The Y-bin selection is critical for applications demanding higher current gain without excessive base drive. Consider the TO-92 package constraints regarding thermal dissipation limits of 1.25W in free air. Verify pinout compatibility with existing PCB layouts, specifically noting the emitter-collector-base arrangement.

Single Bipolar Transistors Part Context

This part belongs to the 2SB772 series of medium-power PNP transistors manufactured by Micro Commercial Components. It serves as the complementary pair to the NPN 2SD882 transistor. The series is engineered for general-purpose switching and amplification tasks where moderate power handling and reliable saturation characteristics are essential for stable operation.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute: KSB772YS (onsemi). Verify electrical parameters and pinout compatibility before substitution.

Single Bipolar Transistors FAQ

What is the DC current gain range for the 2SB772-Y variant?
