Single Bipolar Transistors datasheet and documents for BC557BTA

BC557BTA

Single Bipolar Transistors Overview

The onsemi BC557BTA is a PNP silicon epitaxial planar transistor designed for general-purpose small-signal applications. It operates with a maximum collector current of 100 mA and a collector-emitter voltage rating of -45 V. The device features a minimum DC current gain (hFE) of 200 at 2 mA and 5 V, ensuring reliable amplification performance. It has a transition frequency of 150 MHz and supports a maximum power dissipation of 500 mW. The component is housed in a TO-92 (TO-226AA) through-hole package, suitable for automated assembly processes.

Single Bipolar Transistors Feature Summary

Utilizes silicon epitaxial planar technology for robust small-signal operation
Provides high DC current gain for effective signal amplification
Supports standard through-hole mounting configurations

Single Bipolar Transistors Applications

General-purpose amplifier circuits
Switching applications requiring low to moderate current control
Audio signal processing stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'T' indicates lead-free compliance and RoHS3 status as per manufacturer documentation. Confirm the package type matches the required TO-92 or TO-226AA form factor for your PCB layout. Ensure the hFE binning meets your circuit's gain requirements, as variations exist within the B grade specification. Cross-reference datasheets for absolute maximum ratings to prevent thermal overstress during operation.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 45 V breakdown and 100 mA continuous current capability is required. The BC557BTA offers a balance of gain and speed suitable for audio and intermediate frequency applications. Consider the thermal derating characteristics if operating near the maximum power dissipation limit. Compare against BC556 or BC558 variants if voltage or saturation requirements differ significantly from the 45 V and 30 V limits respectively.

Single Bipolar Transistors Part Context

The BC557BTA belongs to the BC556/BC557/BC558 family of PNP transistors manufactured by onsemi. This series is widely used in consumer electronics and industrial equipment for signal conditioning. The 'B' suffix denotes the current gain grouping, while 'T' typically signifies tape and reel packaging or lead-free composition depending on the specific manufacturing lot and datasheet revision.
