High-Efficiency 85 A MOSFET in D2PAK-3 Package for Automotive and Power Conversion Applications

The SUM85N15-19-E3 is a high-performance N-channel 150 V (D-S) MOSFET from Vishay Semiconductors, engineered for demanding power-conversion, motor-drive, and automotive applications that require high efficiency, low conduction losses, and exceptional thermal handling. Built on Vishay’s advanced TrenchFET® silicon technology, this MOSFET delivers robust switching behavior, low Rds(on), and excellent avalanche ruggedness—attributes that make it a preferred choice for designers seeking reliability under harsh electrical and thermal conditions.

Housed in a compact yet thermally optimized D2PAK-3 (TO-263-3) surface-mount package, the SUM85N15-19-E3 provides very low thermal resistance and a maximum power dissipation rating of 375 W, allowing it to operate confidently even under elevated load conditions. Its 85 A continuous drain current capability, 150 V breakdown voltage, and 175°C maximum junction temperature rating make it suitable for high-current switching in industrial and automotive systems, including 42-V EPS, ABS units, DC/DC converters, and various motor-control architectures.

With a typical gate charge of just 76 nC, along with balanced turn-on and turn-off delay times, the device ensures efficient high-frequency switching and reduced losses across the system. It complies with Vishay’s strict quality controls, including 100% Rg testing, ensuring consistent performance and enhanced reliability during long-term operation.

Whether used as a primary-side switch in high-power SMPS designs or as a key component in battery-powered motor drives, the SUM85N15-19-E3 D2PAK-3 MOSFET represents an optimal combination of ruggedness, thermal performance, and electrical efficiency.
