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.
Maximum on-resistance ratings range from 15 down to 4.2mohm for the six new devices.
Because P-channel mosfets require no additional high-side driver circuitry for turn-on, these new -40 and -60V TrenchFET devices will help designers to reduce component count and improve reliability in automotive and industrial systems compared with N-channel solutions.
When used to replace previous-generation P-channel devices, the new TrenchFETs give designers the opportunity to lower system power consumption as well.
Compared with the next-best P-channel mosfets on the market with the same voltage ratings and package outlines, conduction losses for the new devices are reduced by up to 90%.
Package options for the -40V devices are the standard DPAK (SUD50P04-09L), the thermally enhanced D2PAK (SUM110P04-04L), and the leadless, 1.07mm-high PowerPAK SO-8 (Si7463DP).
The -60V TrenchFETs also are offered in the DPAK (SUD50P06-15L), the thermally enhanced D2PAK (SUM110P06-07L), and PowerPAK SO-8 (Si7463DP).
The DPAK and D2PAK devices are rated for a maximum junction temperature of 175C, whereas the PowerPAK SO-8 TrenchFETs are rated for up to 150C.
Samples and production quantities of the new P-channel TrenchFET power mosfets are available now with lead times of 10 to 12 weeks for larger orders.
Pricing for US delivery starts at $1.10 in 100,000-piece quantities.
