Diodes Incorporated SBR10U200CTB-13-G

Overview

SBR10U200CTB-13-G from Diodes Incorporated is a 10A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 200V peak repetitive reverse voltage, with ultra-low forward voltage (0.65V typ. @ 10A, 25°C) and soft fast switching (trr = 24 ns typ.). It serves as a high-efficiency output rectifier in DC/DC converters and AC/DC secondary-side applications requiring low conduction loss and thermal stability up to +175°C.

For engineers reviewing the SBR10U200CTB-13-G datasheet, SBR10U200CTB-13-G pinout, SBR10U200CTB-13-G application, or SBR10U200CTB-13-G equivalent, key selection criteria include its 200V VRRM rating, 10A total average rectified current, TO263AB thermal resistance (RθJC = 2°C/W), soft-recovery behavior, and RoHS-compliant "Green" packaging - critical for automotive and industrial power supplies where efficiency and reliability under thermal stress are prioritized.

Technical Context

This dual-diode rectifier uses Diodes' patented SBR® technology to achieve Schottky-like forward voltage with significantly improved temperature stability and higher reverse voltage capability than standard Schottky diodes. Its common-cathode configuration supports synchronous or independent leg operation in center-tapped or dual-output topologies.

The device operates across –65°C to +175°C junction temperature, maintains <0.88V VF at 10A and +125°C, and delivers 150A non-repetitive surge current handling - enabling robust performance in transient-heavy environments such as automotive infotainment power rails and industrial motor drive auxiliary supplies.

FAQ

What is the maximum junction temperature and how does it affect derating?

The SBR10U200CTB-13-G has a maximum junction temperature of +175°C. At ambient temperatures above +75°C, average forward current must be linearly derated from 10A to zero at +175°C, per Figure 4 in DS30990 Rev. 11–2. This allows full-rated operation in under-hood automotive environments when properly heatsinked.

Is SBR10U200CTB-13-G AEC-Q101 qualified?

No - SBR10U200CTB-13-G is not AEC-Q101 qualified. Diodes offers AEC-Q101 versions under part numbers like SBR10U200CTBQ-13-G (with Q suffix), which undergo additional stress testing and are manufactured in IATF 16949-certified facilities. Standard SBR10U200CTB-13-G is intended for industrial and commercial applications.

How does the common-cathode configuration impact PCB layout?

The common-cathode pin (Pin 2) must be routed as a low-inductance, wide copper pour to serve both output rails. Anode pins (1 and 3) require separate, symmetrical traces to minimize imbalance. The exposed thermal pad beneath the package must be fully soldered to a dedicated internal or external copper plane for effective heat extraction.

Can this device replace a standard Schottky rectifier in existing designs?

Yes - with caveats. SBR10U200CTB-13-G matches typical Schottky voltage ratings (200V) and current (10A), but its soft recovery and lower VF improve EMI and efficiency. However, layout must accommodate TO263AB's larger footprint and thermal pad; verify thermal relief and solder paste stencil design per Diodes' recommended pad layout (DS30990 p.5).
