BC559BZL1

Single Bipolar Transistors Overview

The BC559BZL1 is a PNP silicon small-signal transistor manufactured by onsemi. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 30 V. The device operates with a transition frequency of 150 MHz and dissipates up to 500 mW of power. It is housed in a TO-92 (TO-226AA) through-hole package. The minimum DC current gain is specified at 180 under defined test conditions.

Single Bipolar Transistors Feature Summary

• PNP polarity configuration for signal amplification
• Through-hole mounting via TO-92 leaded package
• High-frequency operation capability

Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Switching applications requiring low current control
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'ZL1' against official manufacturer documentation, as standard listings often reference the base part number BC559B. Confirm RoHS compliance status and manufacturing origin, as historical data indicates potential variations in lead-free certification for this specific packaging variant. Ensure the component matches the required hFE binning specifications for the intended circuit design.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 30V rating and 100mA continuous current capacity is required. The TO-92 package suits prototyping and low-density PCB layouts. Compare the 150MHz transition frequency against application bandwidth needs. Verify that the 500mW power dissipation limit aligns with thermal management capabilities in the final assembly.

Single Bipolar Transistors Part Context

This component belongs to the BC559 series of general-purpose PNP transistors. It shares electrical characteristics with other variants in the family but differs in packaging and specific gain binning. The BC559 series is widely used in consumer electronics and industrial control systems for low-power switching and amplification tasks.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC559B and BC559C from onsemi or equivalent manufacturers. Verify pinout compatibility and ensure the replacement meets the 30V Vceo and 100mA Ic requirements.
