Four new devices in PowerPAK power MOSFET family

Power Electronics / Power Management
Vishay Siliconix offers its new PowerPAK 1212-8 MOSFETs, including first PowerPAKs with integrated Schottky diode. The key benefits are that it provides superior thermal performance, increased maximum current handling, and increased power dissipation compared with other devices of its size. The MOSFETS can be used to replace devices in packages as large as the TSSOP-8 and can also help reduce 'hot spots' in miniaturised electronic products. The TSSOP-8 package can now be replaced in many designs with a PowerPAK device that is significantly smaller (20,46 mm2 versus 32,6 mm2) and just as thin (1,07 mm).
The first combination power MOSFET and Schottky diode devices in the PowerPAK package, the devices feature low height profiles of 1,07 mm, with footprint areas of 10,56 mm2, and offer ESD protection of up to 4500 V.
Key applications are in battery charger switching and protection applications in cellular and cordless phones, pagers, PDAs and other portable devices.
The PowerPAK 1212-8 Power MOSFETs devices are: Si7900EDN - for single or dual-cell lithium ion battery pack protection; Si7901EDN - bi-directional battery switch for portable electronic systems; Si7703EDN - battery charger switching in portable devices; Si7705DN - battery charger switching in portable devices.
