场效应整流器

较低的漏电流温度系数使其工作更轻松

意法半导体的新型场效应整流二极管(FERD)通过专注于折中升级促进了设计的增强。场效应整流二极管属于我们STPOWER系列。
FERD的设计能够既降低压降又降低漏电流温度系数。因此,失控安全裕度得到了增强,可能超过了肖特基势垒二极管的典型安全裕度。

根据目标应用及其电压,开发人员现在可以在前向压降(VF)和泄漏电流(IR)之间取得完美折中:
 - ‘U’ 非常低的前向压降(VF)
       - ‘L’较低的前向压降(VF)
  - ‘M’与‘SM’中等前向压降,和优化的泄漏电流(IR)
 - ‘H’与‘S’高工作温度下也可实现低漏电电流(低IR


设计人员可以使用我们的波形驱动在线Schottky & FERD eTool 仿真器快速评估最适合其应用的场效应整流器或肖特基二极管。

FERD30H100 - 30 A,100 V器件现在采用DPAK封装!
对于给定的封装尺寸,意法半导体先进的FERD技术比肖特基势垒器件具有更好的密度和更高的效率。最新的60和100V器件具有插件、PowerFLAT™、D²PAK和DPAK封装。更小的、经优化的封装帮助开发人员设计出功耗更低的紧凑型充电器、适配器和SMPS(开关电源),不仅功耗降低,散热器也可以减小。

15 W 5 V output USB adapter board with STCH03 CC-mode primary sensing switching controller

The STEVAL-SMACH15V1 USB adapter evaluation board features high efficiency, extreme low quiescent current, OVP, UVP, OTP, and hiccup-mode protection.

Based on the STCH03 offline PWM controller for low standby adapters, it provides constant output current (CC) regulation using primary sensing feedback.

To help developers choose the best compromise in terms of forward voltage drop (VF) and leakage current (IR), the design includes our FERD20U50 field-effect rectifier diode (FERD) in a PowerFLAT™ package.
