Overview
The PMD4002K is an NPN switching transistor and high-speed switching diode integrated in a SOT346 (SC-59A/TO-236) small Surface-Mounted Device plastic package. Designed as a MOSFET driver, it protects the base-emitter junction in reverse direction. The NPN transistor features a collector-emitter voltage of 40 V, a collector current of 0.6 A, and a peak collector current of 1 A. The internal diode supports a forward current of -0.2 A with a forward voltage of -1.1 V at -200 mA.
Feature Summary
- High-speed switching diode provides protection for the base-emitter junction against reverse polarity.
- Application-optimized pinout minimizes layout effort and reduces overall component count.
- Space-saving solution integrates both transistor and diode functions into a single compact package.
Applications
- Power MOSFET driver
Procurement Notes
Verify the specific ordering suffix to confirm packing quantity and reel specifications. Confirm the device status matches current production requirements. Ensure compatibility with standard FR4 or ceramic PCB mounting footprints. Check thermal resistance values against the intended heat dissipation environment. Validate that the absolute maximum ratings align with the operational stress conditions of the target circuit design.
Selection Notes
Select this component when space constraints require integrating a driver transistor and protective diode. Consider the 40 V collector-emitter voltage rating for low-voltage switching applications. Evaluate the thermal characteristics based on the chosen PCB material and copper area. Ensure the peak current capabilities meet the transient drive requirements of the connected load.
Part Context
This component belongs to the category of discrete semiconductor devices designed for power management and signal switching. It serves as a specialized driver element within larger electronic systems, combining active switching and passive protection functions. The integration aims to simplify circuit board design by reducing the number of individual components required for driving external switches.
