Power MOSFET delivers space savings for small-signal applications.

Press Release Summary:

Housed in 1 x 0.6 x 0.43 mm SOT-923 package, SiM400 is 60 V N-channel power MOSFET that offers on-resistance of 3.9 W at VGS of 10 V, 4.8 W at 4.5 V, and 8 W at 3.5 V. Unit provides ESD protection up to 1,500 V and is lead-free, halogen-free, and RoHS-compliant. It is suited for range of small-signal switching applications including miniaturized motors in digital still/video cameras, electroluminescent backlighting, and boost DC-DC converters.

Original Press Release:

New Vishay Siliconix 60-V SiM400 in 1 x 0.6 mm SOT-923 Delivers Space Savings for Small-Signal Applications

MALVERN, PENNSYLVANIA - Vishay Intertechnology, Inc. (NYSE: VSH) today released a 60-V n-channel power MOSFET in the tiny SOT-923 package that will provide dramatic space savings over devices in larger packages such as the SC-70 and SC-89.

The smallest 60-V power MOSFET ever released, the SiM400's SOT-923 measures 1 mm by 0.6 mm with a maximum height profile of 0.43 mm. Its footprint dimensions are 77% smaller than the SC-89, while its height profile is 26 % thinner.

On-resistance for the new device is 3.9 W at VGS = 10 V, 4.8 W at 4.5 V, and 8 W at 3.5 V.

The SiM400 will serve in a very wide range of small-signal switching applications where minimal board space is available, including miniaturized motors in digital still and video cameras, electro-luminescent backlighting, and boost dc-to-dc converters, where its miniscule dimensions will help to save space and/or enable greater functionality.

Handheld devices tend to use small-signal switching in conjunction with complex controllers such as power management units (PMUs). The SiM400's low on-resistance ratings down to 3.5 V, which is an exceptionally low gate-to-source value for a 60-V device, and its small package size compared to a SC-89, thus represent important benefits.

The environmentally friendly new device is lead (Pb)-free, halogen-free, and RoHS-compliant. It additionally provides ESD protection up to 1500 V.

Samples and production quantities of the SiM400 are available now, with lead times of 10 to 12 weeks for larger orders.
