電界効果整流ダイオード

リーク電流の温度係数を低減し、よりスムーズな開発を実現

STは、バランス特性の改善に重点をおいた電界効果整流ダイオード(FERD)を提供し、設計の改善をサポートしています。STの電界効果整流ダイオードはSTPOWER ファミリの製品です。
独自の設計により電圧降下を減少させるとともに、リーク電流の温度係数を低減するため、熱暴走に対する安全マージンが一般的なショットキー・バリア・ダイオードと同レベル、もしくはそれ以上のレベルに改善されています。

対象アプリケーションおよび電圧に応じて、順方向電圧降下(VF)とリーク電流(IR)の最適なバランスを選択することができます。
- U: きわめて低い順方向電圧降下(VF
- L: 低い順方向電圧降下(VF
- M & SM: 中程度の順方向電圧降下と最適化されたリーク電流(IR
- H & S: 高温下でも小さなリーク電流(低 IR


オンラインのショットキー & FERD eToolシミュレータでは、アプリケーションの波形に基づいて最適な電界効果整流ダイオードやショットキー・ダイオードを素早く発見し、その評価を行うことができます。

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.
