BC556BTA

Single Bipolar Transistors Overview

The BC556BTA is a PNP epitaxial silicon transistor from the BC550 series, designed for switching and amplifier applications. It features a collector-emitter breakdown voltage of 65 V and a maximum continuous collector current of 100 mA. The device operates within a junction temperature range of -65°C to +150°C and dissipates up to 500 mW. Packaged in a TO-92-3 Kinked Lead configuration, it offers a transition frequency of 150 MHz.

Single Bipolar Transistors Feature Summary

• High-voltage capability with a 65 V collector-emitter breakdown rating

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor assets are now managed by onsemi. Confirm that the component matches the exact datasheet specifications for the BC556BTA variant. Ensure the package type corresponds to the TO-92-3 Kinked Lead form factor required for your design constraints.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor is required for low-power applications. The 65 V rating distinguishes it from lower-voltage counterparts like the BC557. Consider the 150 MHz transition frequency for signal integrity requirements in amplifier stages.

Single Bipolar Transistors Part Context

This part belongs to the BC550 family of PNP silicon transistors, which includes variants like the BC556, BC557, and BC558. These devices share similar physical packages but differ in voltage ratings and gain characteristics. The BC556 specifically provides the highest voltage tolerance within the standard low-noise group.

Single Bipolar Transistors Replacement Considerations

The BC556B is a direct functional substitute offering identical electrical parameters. Other compatible replacements include the BC556A and BC556C, which vary primarily in DC current gain ranges rather than voltage or power limits.
