FJPF3305TU

Single Bipolar Transistors Overview

The FJPF3305TU is an NPN bipolar junction transistor manufactured by onsemi, formerly Fairchild Semiconductor. It is housed in a TO-220F-3 through-hole package and rated for a collector-emitter voltage of 400 V with a continuous collector current of 4 A. The device features a maximum power dissipation of 30 W and a transition frequency of 4 MHz. Key electrical characteristics include a DC current gain (hFE) of at least 26 at 1 A and 5 V, and a saturation voltage of 1 V at 1 A base and 4 A collector currents.

Single Bipolar Transistors Feature Summary

• Designed for high-voltage switching applications with a 400 V collector-emitter breakdown rating.
• Provides robust current handling capability with a 4 A continuous collector current limit.
• Engineered for efficient operation with low saturation voltage characteristics under specified load conditions.

Single Bipolar Transistors Applications

• High-voltage switching circuits
• Power supply output stages
• Industrial motor control systems

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully, as onsemi acquired Fairchild Semiconductor's discrete semiconductor business. Confirm the specific suffix TU corresponds to the tube packaging format rather than tape-and-reel variants. Check for obsolescence notices or last-time buy notifications, as this component may be subject to lifecycle changes. Ensure the datasheet version matches the production batch requirements for critical design specifications.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor is required for through-hole mounting in power applications. The 400 V rating distinguishes it from lower-voltage general-purpose transistors. Consider the thermal management requirements associated with the 30 W power dissipation rating in the TO-220F-3 package. Evaluate the transition frequency if high-speed switching performance is a critical design constraint.

Single Bipolar Transistors Part Context

This part belongs to the FJPF3305 series of high-voltage NPN transistors. The series is characterized by its ability to handle significant power levels in standard through-hole packages. The FJPF3305TU variant specifically denotes the tube packaging option, which differs from other availability formats like cut tape or reel. These devices are commonly used in applications requiring reliable high-voltage switching capabilities.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers were not identified in the provided documentation. Verify compatibility with direct replacements by matching the 400 V VCEO, 4 A IC, and TO-220F-3 package dimensions. Consult official replacement guides from onsemi for updated alternatives if this specific part number is discontinued.
