IPL65R070C7AUMA1: A High-Performance 650V CoolMOS™ Power Transistor

The relentless pursuit of higher efficiency and power density in modern electronics demands continuous innovation in power semiconductor technology. The IPL65R070C7AUMA1, a 650V CoolMOS™ power transistor, stands at the forefront of this evolution, engineered to deliver exceptional performance in demanding applications.

At its core, this device leverages the superjunction (SJ) principle, a hallmark of the CoolMOS™ family. This advanced technology enables a drastic reduction in on-state resistance (RDS(on)) for a given silicon area. With a maximum RDS(on) of just 70 mΩ, the IPL65R070C7AUMA1 achieves remarkably low conduction losses. This characteristic is paramount for enhancing the overall efficiency of power conversion systems, as it minimizes the energy wasted as heat during operation.

Beyond low conduction losses, the transistor exhibits superior switching performance. The optimized gate charge (Qg) and low figures of merit (e.g., RDS(on) x Qg) ensure swift turn-on and turn-off transitions. This translates to significantly reduced switching losses, which is especially critical in high-frequency circuits such as switch-mode power supplies (SMPS), power factor correction (PFC) stages, and inverters. By operating efficiently at higher frequencies, designers can utilize smaller passive components like inductors and capacitors, leading to more compact and lightweight end products.

Robustness and reliability are integral to its design. The 650V drain-source voltage rating provides a sufficient safety margin for handling voltage spikes and transients commonly encountered in industrial and automotive environments. Furthermore, the device features a temperature-independent RDS(on) and excellent avalanche ruggedness, ensuring stable and dependable operation under strenuous conditions.

Typical applications where the IPL65R070C7AUMA1 excels include:

Server and telecom power supplies

Industrial motor drives and automation systems

Solar inverters and renewable energy solutions

High-performance charging infrastructure for electric vehicles

Lighting control systems
