Diodes Incorporated SBR10U100CT

Overview

SBR10U100CT from Diodes Incorporated is a 10A dual common-cathode Super Barrier Rectifier rated for 100V peak reverse voltage, featuring low forward voltage (0.56V @ 10A, 25°C), soft fast switching, and operation up to +175°C junction temperature. It serves as a high-efficiency output rectifier in AC/DC power supplies, DC/DC converters, and OR-ing circuits where low conduction loss and thermal stability are critical.

For engineers reviewing the SBR10U100CT datasheet, SBR10U100CT pinout, SBR10U100CT application, or SBR10U100CT equivalent, key selection considerations include its dual-diode TO220AB configuration, 150A non-repetitive surge rating, JEDEC-qualified reliability, and suitability for industrial and automotive-grade designs requiring high-temperature rectification with minimal VF drift.

Technical Context

The SBR10U100CT integrates two independent super barrier diodes in a single TO220AB package with common cathode connection. Its patented SBR® technology replaces traditional PN junctions with a metal-semiconductor structure, delivering lower forward voltage than standard Schottky diodes while maintaining higher reverse blocking capability and superior high-temperature leakage performance.

It operates across –65°C to +175°C, exhibits soft reverse recovery (no hard switching spikes), and maintains stable VF below 0.82V even at 10A and +125°C. Thermal resistance from junction-to-case is 2°C/W (TO220AB), enabling efficient heatsink coupling for continuous 10A operation under controlled ambient conditions.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

The SBR® Super Barrier Rectifier product line targets high-efficiency power conversion systems demanding lower VF than Schottky diodes without sacrificing voltage rating or thermal robustness-specifically for industrial, computing, and automotive power applications.

FAQ

What is the difference between SBR10U100CT and SBR10U100CTFP?

The SBR10U100CT uses the TO220AB package with insulated tab, while the SBR10U100CTFP uses the ITO220AB variant-same die and electrical specs, but ITO220AB features enhanced insulation (2000VAC isolation from terminal to heatsink) and slightly different mechanical dimensions. Both share identical VF, VRRM, and thermal characteristics.

Can SBR10U100CT replace a standard 10A Schottky diode in a 48V supply?

Yes-it is a direct functional replacement with advantages: 100V VRRM provides headroom above 48V nominal, 0.56V VF at 10A lowers conduction loss by ~1.9W versus typical 0.75V Schottkys, and its 175°C rating improves reliability in thermally stressed layouts. No circuit redesign is needed beyond verifying heatsink interface.

Is SBR10U100CT qualified for automotive applications?

The base SBR10U100CT is JEDEC-qualified and AEC-Q101 capable, but Diodes offers automotive-grade variants with Q-suffix (e.g., SBR10U100CTQ) that undergo full PPAP, IATF 16949 manufacturing, and extended stress testing. For production automotive use, the Q-suffix version is required.

How does the SBR® technology differ from conventional Schottky or fast recovery diodes?

SBR® uses a proprietary metal-semiconductor barrier structure that achieves Schottky-like forward conduction (low VF) while suppressing reverse leakage through engineered carrier lifetime control-unlike Schottky diodes (high IR at high T) or fast recovery diodes (high VF and hard switching). This yields best-in-class VF/IR trade-off at 100V.
