BC546TA

Single Bipolar Transistors Overview

The onsemi BC546TA is an NPN epitaxial silicon transistor housed in a TO-92-3 through-hole package. It features a maximum collector-emitter voltage (VCEO) of 65 V and a collector-base voltage (VCBO) of 80 V. The device supports a continuous DC collector current (IC) of 100 mA with a power dissipation (Pd) of 500 mW. Key electrical characteristics include a minimum DC current gain (hFE) of 110, a transition frequency (fT) of 300 MHz, and a maximum operating junction temperature of 150°C.

Single Bipolar Transistors Feature Summary

• High-voltage capability suitable for switching and amplification circuits requiring up to 65 V collector-emitter breakdown.
• Broad DC current gain range allows flexibility in amplifier design without strict binning requirements.
• Lead-free construction complies with environmental standards such as RoHS and REACH.

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Electronic switching circuits
• Driver stages for low-power loads

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official datasheets to confirm hFE binning and packaging format. Confirm lead-free status and RoHS compliance directly with the manufacturer or authorized distributors. Check for obsolescence notices or PCN updates regarding lead frame materials before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with 65 V rating and 100 mA current capacity is required. Ensure the application does not exceed the 500 mW power dissipation limit at the expected ambient temperature. Verify that the required current gain falls within the specified minimum range for the chosen circuit topology.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN transistors from onsemi. The series includes variants differentiated primarily by their DC current gain (hFE) bins. The BC546TA specifically denotes a standard gain variant packaged in TO-92. It serves as a fundamental discrete semiconductor component for analog and digital logic interfacing.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC546BTA, BC546CTA, and BC546ABU from onsemi, which share identical electrical ratings but differ in hFE gain ranges. Other manufacturers offer pin-compatible equivalents such as MMBT3904 or 2N3904, though voltage ratings may vary.
