BC546_J18Z

Single Bipolar Transistors Overview

The BC546_J18Z is an NPN silicon small-signal transistor manufactured by onsemi. It operates with a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. The device features a transition frequency of 300 MHz and a maximum power dissipation of 500 mW. It is housed in a TO-92 (TO-226AA) three-pin package designed for through-hole mounting. The component supports a junction temperature range up to 150 °C and includes a minimum DC current gain (hFE) of 110 at specified test conditions.

Single Bipolar Transistors Feature Summary

• NPN bipolar junction transistor configuration for general-purpose amplification
• High-frequency performance capability suitable for signal processing applications
• Robust thermal stability supporting operation at elevated junction temperatures

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications requiring low-power control
• Signal conditioning stages in electronic systems

Single Bipolar Transistors Procurement Notes

Verify the specific suffix J18Z against official onsemi documentation to confirm binning or packaging variations. Confirm RoHS compliance status as historical data indicates potential non-compliance for certain variants. Ensure the source document explicitly identifies this part number to avoid substitution errors with standard BC546B or BC546TAR equivalents.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with 65V breakdown and 100mA continuous current capacity is required. The TO-92 package facilitates easy integration into through-hole PCB layouts. Consider the 300MHz transition frequency for high-speed switching or amplification needs within the specified power dissipation limits.

Single Bipolar Transistors Part Context

This part belongs to the BC546 family of NPN transistors, widely used in consumer electronics and industrial controls. The BC546 series provides a reliable solution for low-power amplification tasks. Variants within the family typically differ by hFE binning and packaging style, while maintaining core electrical characteristics such as voltage ratings and current handling capabilities.

Single Bipolar Transistors Replacement Considerations

Standard BC546B or BC546TAR from onsemi may serve as functional substitutes if electrical parameters align. Verify pinout compatibility and package dimensions before replacement. Other manufacturers producing equivalent NPN transistors with matching 65V/100mA ratings can be considered after confirming datasheet specifications.
