Key Features
- Ultra-low 0.063Ω drain-source on-resistance at 42A enabling highly efficient power conversion with minimal conduction losses
- 960mJ avalanche energy rating providing exceptional robustness in inductive load switching and unclamped inductive switching events
- D2PAK (TO-263) surface-mount package with drain-connected tab for excellent thermal dissipation on standard PCB copper pours
Applications
The STB57N65M5 is designed for high-current power switching applications including server power supplies, solar inverters, and industrial motor drives operating from high-voltage DC buses up to 650V. Its extremely low on-resistance minimizes power dissipation at 42A continuous drain current, improving overall system efficiency in demanding power conversion stages. The D2PAK surface-mount package with a drain-tab thermal path enables effective heat sinking directly through the PCB without mechanical mounting hardware.

Frequently Asked Questions
What are the voltage, current, and on-resistance ratings of the STB57N65M5?
The STB57N65M5 is rated for a minimum drain-source breakdown voltage of 650V and a maximum continuous drain current of 42A. Its maximum drain-source on-resistance is just 0.063Ω, which significantly reduces conduction losses at high current levels. The device also features a 960mJ avalanche energy rating for operation with inductive loads.
What package does the STB57N65M5 use and how does it manage heat?
The STB57N65M5 uses the D2PAK (TO-263AB) surface-mount package with the case connected directly to the drain. This allows the large exposed tab to conduct heat directly into the PCB copper plane, providing effective thermal management without requiring a separate heatsink or mechanical mounting hardware, simplifying board assembly in high-power applications.
Does the STB57N65M5 include a body diode and what is its avalanche rating?
Yes, the STB57N65M5 is configured as a single device with a built-in anti-parallel freewheeling diode, eliminating the need for an external Schottky or rectifier diode in switching power stages. The device is rated for 960mJ of avalanche energy (Eas), providing a high margin of safety during unclamped inductive switching events typical of motor control and power supply applications.
What applications are best suited for the STB57N65M5?
The STB57N65M5 is optimized for high-efficiency power conversion applications such as three-phase inverters, server and telecom power supplies, solar microinverters, and industrial variable frequency drives. Its 650V rating covers rectified European and universal AC mains voltages, while the ultra-low 0.063Ω on-resistance minimizes switching losses in full-bridge and half-bridge topologies operating at high duty cycles.
