Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched 40 V U-MOSIX-H series N-channel power MOSFET, "TPHR7404PU" suitable for power supplies.
This is a new low-spike-type product using the latest generation process[1] U-MOSIX-H with a low voltage trench structure, having lower On-resistance than TPH1R204PB manufactured by same process.
The new product is able to suppress a low spike voltage which is generated between the drain and source in switching operation, making it suitable for secondary synchronous rectification in switching power supplies that require low EMI. In addition, by featuring industry-leading[2] low On-resistance, the product can help reduce the conduction loss of power supplies.
Both low-spike-type products and high-efficient-type products have been lined up in the U-MOSIX-H series, so users can choose products that are suitable for their applications.
