Vishay Intertechnology, Inc., has released a 60-V n-channel power MOSFET in the SOT-923 package to provide space savings compared with devices in larger packages such as the SC-70 and SC-89.
The smallest 60-V power MOSFET ever released, the SiM400 in the SOT-923 measures 1 mm by 0.6 mm with a maximum height profile of 0.43 mm. The device's footprint dimensions are 77 percent smaller than the SC-89, and its height profile is 26 percent thinner.
On-resistance for the new device is 3.9 Ω at VGS = 10 V, 4.8 Ω at 4.5 V, and 8 Ω at 3.5 V.
The SiM400 will serve in a 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 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.
