2SA673C

Single Bipolar Transistors Overview

The Renesas Electronics Corporation 2SA673C is a silicon PNP small signal bipolar junction transistor designed for general-purpose amplification applications. It features a maximum collector current of 500 mA and a collector-emitter breakdown voltage of 35 V. The device is housed in a TO-92 through-hole package with three pins. Key electrical characteristics include a minimum DC current gain (hFE) of 160 and a power dissipation rating of 400 mW. The component operates within a temperature range up to 125°C or 150°C junction temperature, depending on specific variant specifications.

Single Bipolar Transistors Feature Summary

• Utilizes silicon epitaxial structure for reliable small-signal performance
• Provides high DC current gain suitable for amplifier circuits
• Supports through-hole mounting via standard TO-92 package

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Switching circuits requiring low current control
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the exact suffix designation when ordering, as variants such as 2SA673DRR or 2SA673C-E may exist with identical core specifications but different packaging or reel configurations. Confirm that the required pinout matches the standard TO-92 configuration. Ensure that thermal management requirements align with the 400 mW dissipation limit under intended operating conditions. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS and other regulatory standards applicable to your region.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a robust PNP transistor with moderate current handling capabilities. The TO-92 package is ideal for prototyping and low-volume production where surface-mount space is not a constraint. Consider the 35 V breakdown voltage when designing for higher voltage environments, as it limits applicability in high-voltage switching scenarios. Evaluate the hFE minimum of 160 to ensure sufficient gain for the specific amplifier topology being implemented.

Single Bipolar Transistors Part Context

The 2SA673 series belongs to Renesas' portfolio of discrete semiconductor devices, specifically focusing on small-signal bipolar transistors. These components are widely used in consumer electronics and industrial control systems where reliable switching and amplification are required. The TO-92 form factor remains a standard choice for through-hole applications, offering a balance between cost-effectiveness and ease of manual assembly.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should consult official replacement guides from Renesas or verify pin-compatible alternatives from other manufacturers based on matching electrical parameters such as Vceo, Ic, and package type.
