B772

Single Bipolar Transistors Overview

The EVVO B772 is a PNP bipolar junction transistor housed in an SOT-89 surface-mount package. It supports a continuous collector current of -3 A and offers a collector-emitter breakdown voltage of -30 V with a collector-base voltage rating of -40 V. The device features a maximum power dissipation of 0.5 W and a transition frequency of 50 MHz. DC current gain ranges from 60 to 400 depending on the specific sub-type classification.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin (R, Q, P, or E) required for your circuit design, as gain ranges vary significantly between types. Confirm that the SOT-89 footprint matches your PCB layout constraints. Ensure thermal management accounts for the 0.5 W dissipation limit under operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP switch is needed with high current handling relative to its small SOT-89 package size. Consider the complementary 2SD882 if a matched pair topology is required. Evaluate the specific hFE range needed for your biasing requirements before ordering.

Single Bipolar Transistors Part Context

This component belongs to the general-purpose discrete transistor category. It serves as a high-current alternative to smaller signal transistors while maintaining a low-profile surface-mount form factor suitable for dense board layouts.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies the 2SD882 as the complementary NPN counterpart. Verify pinout compatibility and electrical limits when substituting with other PNP transistors in the SOT-89 package.

Single Bipolar Transistors FAQ

What are the available hFE gain classifications?

The B772 is classified into four types based on DC current gain: Type R (60-120), Type Q (100-200), Type P (160-320), and Type E (200-400).

What is the maximum collector-emitter saturation voltage?

The collector-emitter saturation voltage is typically -0.5 V when tested at a collector current of -2 A and a base current of -0.2 A.
