2N5551 PBFREE

Overview

The 2N5551 PBFREE is a silicon NPN bipolar junction transistor manufactured by Central Semiconductor Corp. It features a maximum collector-emitter voltage of 160 V and a continuous collector current rating of 600 mA. The device operates in a TO-92-3 through-hole package with a power dissipation capacity of 625 mW. Key electrical characteristics include a transition frequency of 250 MHz and a minimum DC current gain of 100 at 150 mA and 1 V. The component supports a wide operating temperature range from -65°C to +150°C.

Feature Summary

• High voltage capability suitable for switching applications requiring up to 160 V collector-emitter breakdown.
• Robust current handling with a 600 mA continuous collector current rating.
• Wide thermal operating range extending to 150°C junction temperature.
• Lead-free construction compliant with RoHS3 standards.

Applications

• General-purpose switching circuits
• Amplifier stages
• Low-power signal processing

Procurement Notes

Verify the specific manufacturer part number against official Central Semiconductor documentation, as generic designations may vary across distributors. Confirm RoHS3 compliance status directly from the datasheet. Check for any product change notices or end-of-life announcements prior to procurement. Ensure the TO-92-3 package type matches the target PCB footprint requirements.

Selection Notes

Select this component when a standard NPN BJT with 160 V blocking capability and 600 mA current handling is required in a through-hole package. Compare the 250 MHz transition frequency against circuit speed requirements. Evaluate the 625 mW power dissipation limit against thermal management constraints in the final assembly. Verify that the TO-92-3 form factor fits the mechanical design.
