Infineon IDP15E65D1: 650V CoolMOS™ Power Transistor in DIP-15 Package for High-Efficiency Applications

The relentless pursuit of higher efficiency and power density in modern electronics drives the need for advanced power semiconductors. Addressing this challenge, Infineon Technologies introduces the IDP15E65D1, a high-voltage power transistor that combines the proven performance of CoolMOS™ technology with the practical benefits of a through-hole package. This device is engineered to serve as a critical component in demanding power conversion systems.

At the core of the IDP15E65D1 is Infineon's revolutionary CoolMOS™ CFD7 technology. This latest generation of superjunction MOSFETs sets a new benchmark for efficiency. It achieves an exceptional balance between minimal on-state resistance (RDS(on)) and low gate charge (QG). This superior combination directly translates to significantly reduced switching and conduction losses, enabling designers to push the boundaries of efficiency in their applications. The transistor boasts a 650V drain-source voltage rating, providing a robust safety margin and enhanced reliability in universal mains applications, including those with unpredictable voltage spikes.

A key differentiator of this component is its DIP-15 through-hole package (TO-252-5L). This package style offers distinct advantages for prototyping, testing, and manufacturing. It provides superior mechanical robustness and excels at managing thermal performance due to its large, solderable tab. This design facilitates efficient heat dissipation away from the silicon die, allowing the device to handle high power levels without compromising longevity. The package is also designed for low stray inductance, which is crucial for minimizing voltage overshoot during fast switching operations.

The technical merits of the IDP15E65D1 make it an ideal solution for a wide array of high-efficiency applications. It is particularly well-suited for:

Switched-Mode Power Supplies (SMPS): Including server, telecom, and industrial power supplies where efficiency standards like 80 Plus Titanium are mandatory.

Power Factor Correction (PFC) Stages: Essential in AC-DC converters to meet harmonic current regulations and improve overall system efficiency.

Solar Inverters and UPS Systems: Where high reliability and efficiency over a wide load range are paramount.

Motor Control and Industrial Drives: For inverters that require robust and fast-switching power devices.

ICGOOODFIND: The Infineon IDP15E65D1 stands out as a highly efficient and robust 650V power MOSFET. Its integration of state-of-the-art CoolMOS™ CFD7 technology into a user-friendly DIP-15 package offers a compelling solution for designers. It effectively bridges the gap between superior electrical performance and practical thermal management, making it a top-tier choice for upgrading the efficiency and power density of next-generation power electronics.
