Vishay Siliconix incorporated announces a trio of 250 V n-channel TrenchFET power MOSFETs that offer the low on-resistance 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/DC converters, including forward converters and half-bridge converters, as well as in AC/DC converters and inverters, for telecom power supplies, distributed architectures, and miniature power modules. The Si4434DY and Si7434DP both feature a maximum on-resistance value of 155mΩ at a 10 V gate drive and a typical gate charge value of 34 nC. In the low-thermal-resistance D2PAK package, the SUM45N25 58 features on-resistance of 58mΩ, a gate charge value of 95 nC, and a maximum junction temperature rating of 175°C.
