BC556B_J35Z

Single Bipolar Transistors Overview

The BC556B_J35Z is a PNP silicon small-signal transistor manufactured by onsemi, housed in a TO-92 (SOT54) plastic package. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 65 V. The device offers a DC current gain (hFE) minimum of 180 at 2 mA and 5 V, with a transition frequency of 280 MHz. Power dissipation is rated at 625 mW, and it operates within a junction temperature range of -55°C to 150°C.

Single Bipolar Transistors Feature Summary

• PNP general-purpose switching and amplification capability
• Low noise performance suitable for signal processing
• High DC current gain for efficient drive requirements

Single Bipolar Transistors Applications

• General purpose switching circuits
• Small signal amplification stages
• Audio pre-amplifier applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix J35Z against official onsemi documentation to confirm pinout and electrical tolerances match design requirements. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Ensure the component source is authorized to avoid counterfeit risks given the part's discontinued status in some regions.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 65V rating and 100mA capacity is required in a through-hole TO-92 package. Compare hFE bins if precise gain control is necessary. Consider thermal management for power dissipation limits near 625 mW. Verify availability of compatible NPN complements like BC546 or BC547 for push-pull configurations.

Single Bipolar Transistors Part Context

This part belongs to the BC556 series of PNP transistors, often paired with NPN counterparts such as the BC546. It serves as a general-purpose device for low-power analog and digital switching tasks. The J35Z suffix typically denotes specific packaging or tape-and-reel variants, though standard TO-92 mechanical dimensions remain consistent across the series.

Single Bipolar Transistors Replacement Considerations

BC556BTA and BC556BTF are confirmed similar substitutes from onsemi. Verify pin compatibility and electrical parameter equivalence before substitution.
