STMicroelectronics’s introduction of a new member of the MDmesh V family has broken the worldwide record for high-voltage power MOSFETs. As the industry’s performance leader, the STW88N65M5 boasts the best on-resistance per area for highest efficiency and power density in 650V rating and can now improve a key efficiency metric by more than 23%. This is a giant leap to energy saving typically lost as heat emitted by power-conversion circuitry used in systems such as electronic lighting controls, power supplies for consumer products, and solar-power converters.

The MDmesh V represents the latest iteration of ST’s well proven Multi-Drain Mesh technology. The enhanced performance will enable customer applications to reduce their energy consumption, underpinning ST’s commitment to provide responsible products for the environment while providing outstanding performance through the design and development of innovative products.

The STW88N65M5 MDmesh V MOSFET features the industry’s lowest on-state resistance for 650V devices in the standard TO-247 package, at 0.029 Ohms. It is better than ST’s previous industry benchmark of 0.038 Ohms, also set by an MDmesh V device. This empowers end application designers to increase energy efficiency by directly replacing MOSFETs of higher resistance or to use fewer devices in parallel and so reduce assembly sizes and Bill-Of-Materials (BOM) costs.

The 650V voltage rating of ST’s STW88N65M5 and other MDmesh V devices provides a greater safety margin than that offered by 600V devices from competing manufacturers. This increases the MOSFET’s ability to withstand voltage surges commonly present on AC power lines.

ST’s market-proven MDmesh V technology is available in a vast range of packages including Max247, TO-247, D2PAK, TO-220/FP, PowerFLAT 8×8 HV and I2PAK.

STMicroelectronics, an independent semiconductor company, engages in the design, development, manufacture, and marketing of a range of semiconductor integrated circuits and discrete devices. Its products include discrete and standard commodity components, application-specific integrated circuits, custom devices and semi-custom devices, and application-specific standard products for analog, digital, and mixed-signal applications. The company also offers subsystems and modules for the telecommunications, automotive, and industrial markets comprising mobile phone accessories, battery chargers, ISDN power supplies, and in-vehicle equipment for electronic toll payment, as well as provides Smartcard products.
