Power MOSFETs in 81% smaller package

8 September 2004 Analogue, Mixed Signal, LSI

Available in the compact 1,6 by 2,4 mm chipscale format with a 0,65 mm height profile, the new bi-directional Vishay Siliconix Micro Foot power MOSFET devices are 81% smaller than TSSOP-8 devices, yet provide similar on-resistance values and better thermal performance, according to the company. The two common-drain, chipscale power MOSFETs are said to be the industry's first such p-channel and 30 V n-channel devices. The 30-V Si8904EDB is a compact solution for battery packs used in portable devices with a traditional common-drain n-channel configuration and offers ultra-low on-resistance of 0,0225 Ω. The 20-V Si8901EDB offers ultra-low effective on-resistance of 0,030 Ω, providing a significant size reduction for lithium-ion and lithium-polymer smart battery packs in portable devices. ESD protection is 6 kV for the Si8901EDB and 4 kV for the Si8904EDB.
