Diodes Incorporated SBR10U200CT

Overview

SBR10U200CT from Diodes Incorporated is a 10A dual common-cathode super barrier rectifier rated for 200V peak reverse voltage, featuring ultra-low forward voltage (0.65V typ. at 10A, 25°C), soft fast switching (trr ≤ 30ns), and high-temperature stability up to +175°C junction temperature. It is used in high-efficiency AC/DC front-end rectification and DC-DC secondary-side synchronous replacement in telecom power supplies.

For engineers reviewing the SBR10U200CT datasheet, SBR10U200CT pinout, SBR10U200CT application, or SBR10U200CT equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJC = 2°C/W), reverse recovery behavior under dI/dt stress, and TO220AB package compatibility with standard heatsink footprints.

Technical Context

This dual-diode SBR device uses patented super barrier technology to achieve Schottky-like low VF while maintaining higher blocking voltage and superior high-temperature leakage performance versus conventional Schottky rectifiers. Its soft recovery minimizes EMI in high-frequency switching converters.

The TO220AB package provides direct metal tab thermal conduction to heatsinks, enabling sustained 10A average current per leg with proper thermal management. The common-cathode configuration supports center-tapped transformer or dual-phase output topologies.

FAQ

Is SBR10U200CT pin-compatible with standard TO220AB dual diodes like MUR1020CT?

Yes, SBR10U200CT uses the standard TO220AB outline with identical mechanical dimensions and 3-pin spacing (2.54mm pitch). Pin 1 = Anode A, Pin 2 = Common Cathode (tab-connected), Pin 3 = Anode B - matching industry-standard dual common-cathode rectifier pinout. No PCB redesign is needed for drop-in replacement.

What is the maximum continuous current per leg with no heatsink at 40°C ambient?

At 40°C ambient and no heatsink, the device is limited by junction temperature: with RθJA ≈ 50°C/W (typ. for TO220AB in still air), max allowable power dissipation is ~2.6W. Given VF ≈ 0.68V at 5A, continuous current is capped at approximately 4.2A per leg to maintain TJ ≤ 150°C - consistent with Fig. 4 derating curve.

Does SBR10U200CT meet AEC-Q101 for automotive use?

SBR10U200CT itself is not pre-qualified to AEC-Q101, but Diodes offers automotive-grade variants (e.g., SBR10U200CTQ) with full AEC-Q101 qualification, PPAP documentation, and IATF 16949 manufacturing. Standard SBR10U200CT may be used in automotive applications under customer-specific change control and qualification protocols.

How does the "soft" recovery characteristic reduce EMI in switch-mode power supplies?

Soft recovery limits the rate of diode current collapse (di/dt) during turn-off, preventing abrupt current zero-crossing and associated high-frequency ringing. This directly suppresses common-mode noise above 30MHz and reduces peak amplitudes in conducted EMI scans - verified in Diodes' application note AN-4001 for 500kHz flyback designs.
