Seven New TrenchFET Power MOSFETs From Vishay Siliconix Combine 175°C Maximum Junction Temperature and Logic Level Gate Drive for Desktop PCs and Automotive Systems

SANTA CLARA, CALIFORNIA - March 4, 1999 - Vishay Siliconix is adding to the options available to automotive and desktop computer designers with seven new n-channel TrenchFET power MOSFETs for dc-to-dc conversion and motor control applications. The new devices combine a robust 175°C maximum junction temperature rating with guaranteed on-resistance specifications for 4.5-V logic level operation, simplifying the microcontroller interface in desktop computer and automotive systems.

With a 30-V breakdown voltage, the new SUB70N03-09P (D2PAK), SUP70N03-09P (TO-220), and SUD50N03-10P (DPAK) combine low on-resistance with reduced gate charge for maximum efficiency in dc-to-dc conversion applications over the full load range. For all three TrenchFETs, maximum on-resistance is just 15 milliohms at a 4.5-V gate drive while typical gate charge is just 45 nC. Maximum current handling of 70 A for the D2PAK and TO-220 devices, and 50 A for the DPAK device, make these TrenchFETs a rugged option for desktop computer dc-to-dc conversion applications as well as for controlling seat positioning, HVAC, and other small motors in automotive systems.

Four additional TrenchFETs for similar applications were also released today. For designs requiring the headroom of a higher breakdown voltage, the SUB75N06-12L (D2PAK) and SUP75N06-12L (TO-220) combine a maximum VDS of 60 V with on-resistance of 12 milliohms at a 10-V gate drive. Maximum current handling for both devices is a full 75 A. For cost-sensitive applications with lower headroom requirements, the new SUB45N03-13L (D2PAK) and SUP45N03-13L combine maximum on resistance of 13 milliohms at 10 V with a 30-V breakdown voltage, with maximum current handling of 70 A for both devices.

"These new TrenchFETs make the microcontroller interface a no-brainer for automotive systems," said Evan Lambka, Product Marketing Manager at Vishay Siliconix, "while in desktop computers their robust thermal and current handling capabilities provide an extra measure of reliability compared with many of the devices currently used in dc-to-dc conversion applications."

Samples and production quantities of all seven new TrenchFETs are available now, with lead times of 8 to 12 weeks for larger orders.
