P-channel MOSFETs for active clamps
A new family of -150 and -200V P-channel power MOSFETs offers space-saving solutions for active clamp configurations.
A new family of -150 and -200V P-channel power MOSFETs from Siliconix offers space-saving solutions for active clamp configurations Although P-channel MOSFETs for active clamps offer a simpler alternative to N-channel clamp implementations, until now the majority of devices suitable for this application were available only in larger packages such as the SO-8 and DPAK

Novel power package reduces MOSFET on-resistance
Siliconix has released 14 industry-leading PowerPAK power MOSFETs featuring improved package technology that yields lower on-resistance devices.
Drivers integrate MOSFETs with drive circuitry
Five new Little Foot Plus driver products are designed to simplify the use of N-channel MOSFETs in high-frequency buck regulators.
With the new devices in the SOT-23 and SC-70, Siliconix brings together small size and on-resistance values at least 80% better than the nearest competing devices.
Built on Siliconix's advanced P-channel TrenchFET technology, the compact dimensions of these new P-channel power MOSFETs reduce board space requirements to enable smaller overall product design without sacrificing performance.
Because P-channel drive circuitry is less complicated than that of N-channel solutions, these new devices also allow designers to implement smaller, lower-cost active clamp designs in small and intermediate-sised power convertors.
The power MOSFETs released today are intended for primary-side active clamp circuits in DC/DC convertors for telecomms, datacomms and industrial products.
With on-resistance values ranging from 1.2 to 2.35ohms, these power MOSFETs represent industry-best on-resistance for their respective footprints.
In addition to these devices in the SC-70 and SOT-23, Siliconix is releasing two PowerPAK SO-8 devices for the same application.
The -150-V Si7439DP offers on-resistance of 0.09mohm, and the -200-V Si7431DP is rated for 0.174mohm.
Samples and production quantities of the new devices are available now, with lead times of 12 weeks for larger orders.
Pricing for US delivery in 100,000-piece quantities starts at $0.20.
