BC307_J35Z

Single Bipolar Transistors Overview

The BC307_J35Z is a PNP silicon small-signal bipolar junction transistor manufactured by onsemi. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V. The device is housed in a TO-92 (TO-226) through-hole package with three leads. Key electrical characteristics include a transition frequency of 280 MHz, a maximum power dissipation of 350 mW, and a DC current gain (hFE) of at least 420 when tested at 2 mA and 5 V. The saturation voltage is specified at a maximum of 250 mV under conditions of 5 mA base current and 100 mA collector current.

Single Bipolar Transistors Feature Summary

• PNP silicon construction for general-purpose switching and amplification
• High DC current gain suitable for low-level signal processing
• Through-hole TO-92 packaging for standard board mounting

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Low-noise amplifier stages
• Driver circuits for larger transistors or relays

Single Bipolar Transistors Procurement Notes

Verify the specific suffix J35Z against official onsemi documentation to confirm binning or testing criteria. Confirm RoHS compliance status as historical data indicates variations across manufacturers. Ensure the source document explicitly lists this exact part number to avoid substitution errors with generic BC307 equivalents.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring a PNP transistor with moderate current handling and high gain. The TO-92 package limits thermal dissipation, so ensure adequate heat sinking or duty cycle management. Compare hFE bins if precise gain matching is required for the specific application circuit design.

Single Bipolar Transistors Part Context

The BC307 series represents a legacy family of PNP small-signal transistors widely used in analog and digital logic interfaces. The J35Z suffix typically denotes a specific manufacturer lot or binning code rather than a functional variant. This component belongs to the broader category of through-hole discrete semiconductors historically produced by Fairchild Semiconductor before its integration into onsemi.
