2SC4559

Single Bipolar Transistors Overview

The Panasonic 2SC4559 is a silicon NPN triple diffusion planar transistor designed for high breakdown voltage and high-speed switching applications. It features a collector-emitter voltage (VCEO) of 400 V with the base open, supporting a continuous collector current of 7 A and a peak current of 15 A. The device operates within a junction temperature range up to 150°C and dissipates 35 W at 25°C case temperature. Key electrical characteristics include a transition frequency (fT) of 10 MHz at IC=0.5 A, a turn-on time of 1.0 µs, and a fall time of 0.3 µs under specified pulsed conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific lifecycle status on the manufacturer's website before procurement, as this component may be in maintenance or discontinued phases. Confirm that the RoHS Directive compliance meets your regional regulatory requirements. Ensure thermal management designs account for the specified power dissipation limits and junction temperature constraints during operation.

Single Bipolar Transistors Selection Notes

Select this component when circuit designs require a 400 V NPN transistor with moderate switching speeds around 10 MHz. Consider the TO-220F-A1 package for efficient heat sinking solutions where mechanical mounting simplicity is preferred. Evaluate the safe operating area curves to ensure the device remains within thermal and electrical limits during both DC and pulsed operations.

Single Bipolar Transistors Part Context

This part belongs to Panasonic Electronic Components' lineup of silicon NPN triple diffusion planar transistors. It is housed in an EIAJ SC-67 (TO-220F-A1) package, which facilitates reliable thermal performance through direct heat sink attachment. The technology focuses on balancing high voltage withstand capabilities with sufficient speed for general-purpose switching tasks.

Single Bipolar Transistors Replacement Considerations

Consult official Panasonic documentation for verified substitute part numbers. Cross-referencing should prioritize components with matching VCEO ratings, package types, and switching characteristics to ensure functional compatibility without redesigning the thermal or drive circuitry.
