BC557ZL1

Single Bipolar Transistors Overview

The BC557ZL1 is a PNP silicon epitaxial planar transistor manufactured by onsemi, housed in a TO-92 (TO-226AA) three-pin through-hole package. It features a maximum collector current of -100 mA and a collector-emitter voltage rating of -45 V. The device operates within a junction temperature range of -55°C to 150°C with a maximum power dissipation of 500 mW. Key electrical characteristics include a minimum DC current gain (hFE) of 180 for the Z suffix variant and a transition frequency of 150 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE binning requirements against the datasheet specifications for the Z suffix. Confirm that the TO-92 package dimensions align with the target PCB layout constraints. Ensure thermal management strategies account for the 500 mW power dissipation limit under operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a minimum hFE of 180 is required. Compare against other BC557 variants if different gain ranges are needed. Consider the 150 MHz transition frequency for high-speed switching needs relative to lower-frequency alternatives.

Single Bipolar Transistors Part Context

This part belongs to the BC557 series of PNP transistors from onsemi. It shares the same physical package and basic voltage/current ratings as other members like BC557B but differs in gain classification. The Z suffix indicates a specific gain binning tier defined by the manufacturer's testing criteria.
