国际整流器公司(IR)日前推出全新额定100V IRF7495和额定80V IRF7493,N沟道HEXFET功率MOSFET,这些产品均经过特别优化,适用于电信系统中采用隔离式全桥或半桥电路的直流一直流转换器。 IRF7495和IRF7493的器件通态电阻和栅漏电荷极低,最适合开关频率为500KHz或以下的转换器。 IRF7495专为通用电信输入电压在36V～75V范围内或可调式48V系统的半桥及全桥电路而设计。与同类器件相比,其组合通态电阻(R_(DS(on)))和栅电荷(Q_c)评测指数降低
International Rectifier (IR) today introduced the new 100V rated IRF7495 and rated 80V IRF7493, N-channel HEXFET power MOSFETs that have been specifically optimized for DC-DC conversion in isolated full-bridge or half-bridge circuits in telecommunications systems Device. Devices such as the IRF7495 and IRF7493 have extremely low on-state resistance and gate-to-drain charge and are ideally suited for converters with a switching frequency of 500 KHz or below. The IRF7495 is designed for use in general-purpose telecom half-bridge and full-bridge circuits with input voltages ranging from 36V to 75V or adjustable 48V systems. Compared with similar devices, the combined on-state resistance (R_ (DS (on))) and gate charge (Q_c)
