New Automotive TrenchFETs® from Vishay Include First 60-V Devices In LITTLE FOOT® TSOP-6 and Low On-Resistance Devices in TO-220 and D²PAK

MALVERN, PENNSYLVANIA - November 4, 1999 - Eight new power MOSFETs for automotive applications, including the first LITTLE FOOT TSOP-6 devices rated at 60-V and new low on-resistance devices in the D2PAK and TO-220, were released today by Vishay Intertechnology, Inc. The new Vishay Siliconix TrenchFETs provide a new range of options for driving small motors and solenoids in automotive systems, allowing designers to select the best combination of breakdown voltage, package size, and performance for their applications.

"Because there is a positive correlation between on-resistance and breakdown voltage, automotive designers using power MOSFETs need to choose a precise optimum point on this tradeoff to ensure that they are using the most cost-effective solution for their applications," said Evan Lambka, Product Marketing Manager. "With these new TrenchFETs, the choices available to them are significantly enlarged and improved."

For highly space-constrained applications, the new Si3458DV (n-channel) and Si3459DV (p-channel) are the first 60-V power MOSFETs in Vishay Siliconix's LITTLE FOOT TSOP-6 package with a footprint of just 3 mm by 2.95 mm. As a higher-performance alternative to SOT-23s, the TSOP-6 products offer on-resistance of 100 milliohms for the n-channel device and 220 milliohms for the p-channel device. In addition to automotive applications, the TSOP-6 devices are also suitable for data storage applications, office automation programmable controllers, and industrial battery packs.

For automotive applications requiring the lowest possible on-resistance, Vishay Siliconix is introducing four new devices in the TO-220 and D²PAK. The new 55-V n-channel SUP75N05-07 (TO-220) and SUB75N05-07 (D²PAK) offer maximum on-resistance of just 7 milliohms, while the 60-V n-channel SUP75N06-06 (TO-220) and SUB75N06-06 (D²PAK) provide an r(DS)on limit of just 6.5 milliohms.

Completing the new automotive offerings from Vishay Siliconix are two n-channel TrenchFETs with a 75-V maximum breakdown voltage rating. The higher breakdown voltage of the new SUP75N08-09L (TO-220) and SUB75N08-09L (D2PAK) provides more headroom for voltage spikes and allows the use of these devices with no extra protection on dual battery systems, while on-resistance is a low 9 milliohms.

Samples and production quantities of all 8 new TrenchFETs are available now, with lead times of 8 to 10 weeks for larger orders.
