NEW 250-V N-CHANNEL TRENCHFET POWER MOSFETS
28 January 2004 - Vishay Electronic

Siliconix incorporated, an 80.4%-owned subsidiary of Vishay Intertechnology, Inc., today released a trio of 250-V n-channel TrenchFET power MOSFETs that offer the lowest on-resistance available in the SO-8, PowerPAK SO-8, and D2PAK packages for this voltage rating.

The Si4434DY (LITTLE FOOT SO-8), Si7434DP (PowerPAK SO-8), and SUM45N25-58 (D2PAK) are designed to serve as primary switches in dc to dc converters, including forward converters and half-bridge converters, as well as in ac-to-dc converters and inverters, for telecom power supplies, distributed architectures, and miniature power modules.

The new devices offer greatly improved on-resistance values compared with competing devices of the same size. The Si4434DY and Si7434DP both feature a maximum on-resistance value of 155 mΩ at a 10-V gate drive and typical gate charge value of 34 nC. In the low-thermal-resistance D2PAK package, the SUM45N25-58 features on-resistance on 58 mΩ, a gate charge value of 95 nC, and a maximum junction temperature rating of 175 °C.

Samples and production quantities of the 250 V Si4434DY, Si7434DP, and SUM45N25-58 n-channel power MOSFETs are available now, with lead times of 10 to 12 weeks for larger orders.
