2N5682

Overview

The 2N5682 is a silicon NPN bipolar junction transistor (BJT) manufactured by Microchip Technology. It is designed for through-hole mounting in TO-92 packages. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 40 V and a collector-base voltage (VCBO) of 60 V. The device supports a continuous collector current of up to 100 mA with a power dissipation rating of 625 mW. It features a transition frequency (fT) of at least 20 MHz, suitable for general-purpose switching and amplification applications within an operating temperature range of -55°C to +175°C.

Feature Summary

• High-temperature operation capability up to +175°C
• Through-hole TO-92 package construction
• Silicon NPN bipolar junction technology

Applications

• General-purpose switching circuits
• Low-power amplification stages
• Temperature-compensated oscillator designs

Procurement Notes

Verify the specific manufacturer source, as the 2N5682 designation may be held by multiple vendors including Central Semiconductor or Rectron under license. Confirm RoHS compliance status and exact packaging type (tube vs. bulk) directly with the supplier. Ensure the datasheet matches the required voltage and current ratings for your specific circuit design before finalizing procurement.

Selection Notes

Select this component when a standard NPN BJT with 40V VCEO and 100mA Ic capability is required in a TO-92 package. Consider the high maximum junction temperature of +175°C for environments exceeding standard industrial limits. Compare fT specifications against signal frequency requirements to ensure adequate gain-bandwidth performance for the intended application.

Part Context

The 2N5682 belongs to the broader family of military-grade and commercial silicon NPN transistors produced by Microchip Technology and its licensed partners. These devices are commonly used in aerospace, defense, and industrial equipment where reliability and wide temperature ranges are critical. The part number follows the JEDEC registration standard for NPN small-signal transistors.

Replacement Considerations

Potential substitutes include the 2N5681 (higher voltage rating), MPS6513, or MPS6514 from the same manufacturer family. Cross-reference with Central Semiconductor CSY5682 or Rectron equivalents if sourcing from alternative distributors. Verify pinout compatibility and thermal characteristics before substitution.
