Diodes Incorporated SBR10U60CT

Overview

SBR10U60CT from Diodes Incorporated is a 10A dual common-cathode Super Barrier Rectifier rated for 60V peak reverse voltage, featuring ultra-low forward voltage (0.42V typ. at 10A, 25°C), soft fast switching, and TO-220AB package with isolated heatsink mounting capability. It serves as a high-efficiency output rectifier in AC/DC power supplies and DC/DC converters for telecom and industrial equipment.

For engineers reviewing the SBR10U60CT datasheet, SBR10U60CT pinout, SBR10U60CT application, or SBR10U60CT equivalent, key selection criteria include forward voltage drop at 10A, thermal resistance (2°C/W junction-to-case), peak surge current rating (150A), and RoHS-compliant green molding compound compatibility with automated reflow assembly.

Technical Context

This dual-leg common-cathode rectifier integrates two independent SBR die in a single TO-220AB thermally optimized package, enabling synchronous half-wave rectification without external paralleling. Its patented super barrier structure replaces traditional PN junctions to reduce VF while maintaining low leakage (<0.5mA at 60V, 25°C) and high-temperature stability up to +150°C junction temperature.

The device operates with soft recovery characteristics-minimizing EMI in high-frequency SMPS designs-and supports isolation-rated mounting (2000VAC terminal-to-heatsink for ITO variant). Thermal derating begins at 25°C ambient, with full 10A rating maintained only below 75°C case temperature per Fig. 4.

Key Specifications

Pinout & Package

TO-220AB package with three terminals: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). Case is electrically isolated and thermally conductive; mounting screw hole centered on tab allows mechanical attachment to heatsink without electrical shorting.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.

Compared with SBRT10U60CT, SBR10U60CT offers 2°C/W better thermal performance but lacks isolation; versus MBR1060CT, it delivers 46% lower VF and extended 150°C operation-critical for high-density, high-efficiency power conversion where thermal headroom and EMI control are design constraints.

FAQ

What is the maximum allowable case temperature for continuous 10A operation?

The SBR10U60CT maintains full 10A average current rating only when case temperature remains ≤75°C, as shown in Fig. 4 of DS30952. Above this, current must be linearly derated to 0A at 150°C. This reflects its 2°C/W RθJC and 150°C maximum junction temperature specification.

Is the TO-220AB package electrically isolated from the leads?

No-the TO-220AB variant has an electrically connected metal tab; only the ITO-220AB version provides 2000VAC isolation between terminals and heatsink. For SBR10U60CT, the tab is internally connected to the cathode (Pin 2), requiring insulating hardware when mounted to grounded heatsinks.

How does the SBR technology differ from standard Schottky rectifiers in high-temperature operation?

Unlike conventional Schottky diodes whose VF increases and IR escalates rapidly above 100°C, the SBR10U60CT maintains VF ≤0.62V and IR ≤100µA at 125°C due to its patented barrier structure-enabling stable performance in sealed, convection-cooled enclosures where thermal management is limited.

Can SBR10U60CT replace MBR1060CT in existing designs without layout changes?

Yes-both use identical TO-220AB footprint and pinout (A-K-A), allowing direct drop-in replacement. However, designers must verify thermal margin: SBR10U60CT's lower VF reduces power dissipation by ~3.3W at 10A, potentially enabling smaller heatsinks or higher ambient operation without redesign.
