BC337-25ZL1G

Single Bipolar Transistors Overview

The BC337-25ZL1G is an NPN silicon small-signal transistor manufactured by onsemi. It features a maximum collector current of 800 mA and a collector-emitter voltage rating of 45 V. The device is housed in a TO-92 (TO-226AA) through-hole package with three leads. Key electrical specifications include a minimum DC current gain (hFE) of 250 at a collector current of 100 mA, a transition frequency of 150 MHz, and a maximum power dissipation of 625 mW. The component operates within a junction temperature range of -55 °C to +150 °C.

Single Bipolar Transistors Feature Summary

• High DC current gain for effective signal amplification
• Designed for general-purpose switching applications
• Low saturation voltage for efficient power handling

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications in consumer electronics
• Driver stages for low-power loads

Single Bipolar Transistors Procurement Notes

Verify the specific suffix '25' indicates the required hFE binning for your design, as this variant offers higher gain than standard versions. Confirm the 'ZL1G' packaging code corresponds to tape-and-reel delivery if automated assembly is required. Ensure the manufacturer is onsemi, as other vendors produce equivalent part numbers with potentially different qualification standards.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is needed for amplification or switching tasks requiring up to 800 mA. The TO-92 package suits prototyping and low-volume through-hole designs. Compare against lower-gain variants like the BC337-16 if cost reduction is prioritized over signal amplification performance.

Single Bipolar Transistors Part Context

This part belongs to the BC337 family of NPN transistors, widely used in audio and RF circuits. The '25' designation specifies the current gain group, distinguishing it from the -16 and -40 variants. The 'G' suffix typically denotes lead-free and RoHS compliance, aligning with modern environmental manufacturing standards.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC337-25 from other manufacturers such as Diodes Incorporated or STMicroelectronics, provided they match the 45V/800mA ratings and TO-92 package. Verify pinout compatibility and thermal characteristics before substitution.
