Infineon IPA70R600P7S: A 600V CoolMOS™ P7 Power Transistor for High-Efficiency Applications

The relentless pursuit of higher efficiency and power density in modern electronic systems places immense demands on power switching components. Addressing this challenge, the Infineon IPA70R600P7S stands out as a premier 600V superjunction MOSFET from the esteemed CoolMOS™ P7 family. This transistor is engineered to set new benchmarks in performance, particularly for power supplies, solar inverters, industrial motor drives, and lighting applications.

A core strength of the IPA70R600P7S is its exceptionally low figure-of-merit (R DS(on) x Q g). This critical parameter signifies an optimal balance between low conduction losses and low switching losses. With a maximum on-state resistance (R DS(on)) of just 70 mΩ, the device minimizes power loss when fully switched on, leading to cooler operation and higher efficiency. Concurrently, its low gate charge (Q g) ensures rapid switching transitions, which is paramount for high-frequency operation. This allows designers to increase switching frequencies without a prohibitive efficiency penalty, enabling the use of smaller, lighter passive components like magnetics and capacitors, thereby significantly boosting overall power density.

The CoolMOS™ P7 technology incorporates several innovative features that enhance robustness and reliability. It offers superior intrinsic body diode robustness, which is crucial for handling hard commutation events, especially in bridge topologies like totem-pole PFC. This inherent ruggedness reduces the need for external protective circuitry, simplifying design and lowering system cost. Furthermore, the technology provides heightened resilience against unexpected operating conditions, contributing to a more reliable end product.

Another significant advantage is the device's integrated additional functional features. The IPA70R600P7S includes a temperature sensor, facilitating accurate and straightforward over-temperature protection. This allows the control circuitry to react proactively to thermal overloads, safeguarding the transistor and the entire system from damage. This level of integrated protection is a valuable asset for creating robust and maintenance-friendly power systems.

Designed for ease of use, the component is offered in the industry-standard TO-220 FullPAK package, ensuring both mechanical robustness and excellent thermal performance for effective heat dissipation.

ICGOODFIND: The Infineon IPA70R600P7S is a top-tier 600V power MOSFET that masterfully combines ultra-low switching and conduction losses with enhanced ruggedness.
