2N5772

Overview

The 2N5772 is an NPN switching transistor manufactured by onsemi, originally documented under Fairchild Semiconductor. It utilizes a TO-92 package and operates with a collector-emitter voltage of 15 V and a collector current of 300 mA. The device features a total power dissipation of 350 mW at 25°C. Key electrical characteristics include a DC current gain ranging from 15 to 120 depending on operating conditions, and a collector-base breakdown voltage of 40 V. Switching performance includes a turn-on time of 18 ns and a turn-off time of 28 ns.

Feature Summary

Designed for general-purpose switching applications using process 22 technology.
Provides high DC current gain suitable for low-power signal amplification and switching tasks.
Features fast switching times including storage, turn-on, and turn-off durations.

Applications

General-purpose switching circuits
Low-power signal amplification
Logic interface circuits

Procurement Notes

Verify the manufacturer origin as the datasheet references Fairchild Semiconductor while the brand is listed as onsemi. Confirm the specific revision status (Rev. B) and ensure the component meets RoHS requirements if applicable to the target assembly. Check for any obsolescence notices or lifecycle changes associated with this legacy part number before finalizing procurement plans.

Selection Notes

Select the 2N5772 when a small-signal NPN transistor with moderate current handling capability is required in a compact TO-92 package. Consider its thermal resistance limits and maximum junction temperature constraints during design. Ensure the application does not exceed the specified collector current or power dissipation ratings to maintain reliability.

Part Context

This component belongs to the family of bipolar junction transistors (BJTs) designed for discrete switching and amplification roles. It serves as a fundamental active element in electronic circuits requiring reliable NPN conduction characteristics within a standard through-hole form factor.

Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Generic replacements must match the TO-92 package, NPN polarity, and similar voltage/current ratings without altering circuit functionality.

FAQ

What is the maximum collector-emitter voltage rating?

The absolute maximum collector-emitter voltage (VCEO) is 15 V.

Does the 2N5772 support high-frequency operation?

It has a small-signal current gain (hfe) of 3.5 at 100 MHz, indicating limited high-frequency amplification capability compared to dedicated RF transistors.
