BC557_J35Z

Single Bipolar Transistors Overview

The BC557_J35Z is a PNP silicon planar epitaxial transistor manufactured by onsemi. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V. The device operates with a transition frequency of 150 MHz and supports a maximum power dissipation of 500 mW at 25°C ambient temperature. It utilizes a TO-92-3 through-hole package and maintains an operating junction temperature range up to 150°C.

Single Bipolar Transistors Feature Summary

• PNP bipolar junction transistor configuration for signal amplification
• Small-signal design optimized for general-purpose switching applications
• Lead-free construction compliant with environmental standards

Single Bipolar Transistors Applications

• General-purpose small-signal amplification
• Electronic switching circuits
• Driver stages in low-power systems

Single Bipolar Transistors Procurement Notes

Verify the specific suffix J35Z against official onsemi documentation to confirm pinout orientation and mechanical dimensions, as suffixes often denote tape-and-reel packaging or specific lead forming variations rather than electrical changes. Confirm RoHS compliance status directly from the manufacturer datasheet before integration into regulated assemblies.

Single Bipolar Transistors Selection Notes

Select this component when a standard PNP small-signal transistor with 45V rating and 100mA capacity is required in a TO-92 package. Ensure the application does not exceed the 500mW power dissipation limit without thermal derating. Verify that the hFE gain bin matches the circuit requirements, as the base model BC557 typically offers a minimum gain of 110 under specified test conditions.

Single Bipolar Transistors Part Context

This part belongs to the BC557 family of PNP transistors produced by onsemi. The BC557 series is widely recognized for its reliability in consumer electronics and industrial control applications. The J35Z suffix indicates specific manufacturing or packaging attributes defined by onsemi, distinguishing it from other variants within the same electrical specification family.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC557C from Diotec Semiconductor and BC557BTFR from Fairchild Semiconductor. These alternatives share identical electrical ratings and TO-92 packaging, ensuring functional compatibility in existing designs without requiring schematic modifications.
