High-Voltage Power MOSFETs Offer Many Spec Variations

Six types of high-voltage P-channel power MOSFETs are supplied in two different breakdown voltage ratings, six different on-resistance (r(DS)on) values and three package variations. The SUM110P04-04L, Si7463DP and SUD50P04-09L are -40V breakdown devices, while the SUM110P06-07L, Si7461DP and SUD50P06-15L are rated for -60V. On-resistance values at 10V range from a low of 4.2 m? for the SUM110P04-04L to a high of 15 m? for the SUD50P06-15L. Packaging options are the thermally-enhanced D2PAK (SUM110P04-04L and SUM110P06-07L), standard DPAK (SUD50P04-09L and SUD50P06-15L), and leadless PowerPAK SO-8 (Si7463DP and Si7461DP). DPAK and D2PAK devices are rated for a maximum junction temperature of 175°C while PowerPak SO-8 devices are rated for 150°C. Target applications are in 12-V automotive systems and electric motor drives where a P-channel eliminates the need for a high-side driver for turn-on. Conduction losses are reduced up to 90% compared to other devices with similar ratings in the same type packages, the company says. Pricing starts at $1.10 each/100,000.
