BC556BZL1G

Single Bipolar Transistors Overview

The BC556BZL1G is a PNP silicon small-signal amplifier transistor manufactured by onsemi. It features a maximum collector-emitter voltage of -65 Vdc and a continuous collector current rating of -100 mAdc. The device operates within a junction temperature range of -55 to +150 °C and offers a DC current gain (hFE) ranging from 120 to 420 at specific test conditions. Packaged in a TO-92 (TO-226AA) housing with three pins, it supports lead-free construction.

Single Bipolar Transistors Procurement Notes

Verify the ordering suffix ZL1G corresponds to the Ammo Box shipping configuration containing 2000 units per box. Confirm the Pb-Free designation matches project environmental requirements. Ensure the TO-92 Style 17 pinout aligns with the target PCB footprint design before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -65 V collector-emitter breakdown voltage is required. Consider the hFE binning options if specific gain ranges are necessary for circuit stability. Evaluate thermal resistance characteristics against the expected ambient operating temperatures to ensure safe operation within the specified limits.

Single Bipolar Transistors Part Context

This part belongs to the BC556/BC557/BC558 family of PNP silicon transistors designed for amplifier applications. The BC556 variant specifically provides higher voltage ratings compared to its lower-voltage counterparts. The ZL1G suffix indicates a specific packaging format distinct from bulk or tape-and-reel options offered for other variants in the series.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC556BG and BC556B from onsemi. Cross-manufacturer equivalents such as NXP BC556B or Diodes Incorporated BC556PL may be considered if electrical parameters match the application requirements.
