Product catalog summary

Introduction
Diodes Incorporated has introduced Super Barrier Rectifier (SBR) technology, which enhances traditional Schottky diodes by offering high power, low loss, and fast switching capabilities. SBRs provide lower forward voltage and improved thermal stability.

Key Features of SBR Technology

Manufactured using a MOS process for superior performance.
Lower forward voltage (VF) than Schottky diodes.
Reduced leakage current in reverse bias.
High thermal stability and reliability.

Applications

Switch Mode Power Supplies (SMPS)
DC-DC Conversion
Battery Chargers
Reverse Polarity Protection
Solar Panels
LED Lighting
Automotive Applications

Product Portfolio
The SBR range includes rectifiers with various voltage and current ratings, detailed with specific part numbers and electrical characteristics.

Product Benefits

Low forward voltage drop and high temperature reverse leakage characteristics.
Large safe operating area for reliability.
Qualified to AEC-Q101 automotive standards and RoHS compliant.

Package Advantages

PowerDI®123 and PowerDI®5 packages offer superior thermal performance and reduced footprint.
High ESD protection and avalanche power rating for reliability.

Conclusion
SBR technology by Diodes Incorporated offers efficiency and reliability advantages, making it a preferred choice in the semiconductor industry.

Specifications
The brochure lists SBR models with specifications such as maximum average rectified current, peak repetitive reverse voltage, and more. Models range from 40V to 300V with current ratings from 1A to 60A.

Product Benefits
SBRs improve forward voltage drop by 20-25% compared to traditional rectifiers, leading to power savings. They operate at a maximum junction temperature of 175°C, suitable for high ambient temperatures, with fast switching speeds and higher VRRM ratings.

Comparison with Other Rectifiers
SBRs have comparable switching speeds to ultra-fast rectifiers but with lower VF, resulting in better efficiency. They also have fast reverse recovery times similar to Schottky and ultra-fast rectifiers.

Applications
SBRs are used as output rectifiers, freewheel diodes, buck/boost diodes, and reverse polarity protection diodes.

Incorporated's SBR portfolio's continual market adoption and increasing market share. SBR – The Next Generation of Rectifiers Super Barrier Rectifier (SBR) is a proprietary and patented Diodes Inc technology that utilizes a MOS manufacturing process (traditional Schottky uses a bipolar process) to create a superior two terminal device that has a lower forward voltage (VF) than comparable Schottky diodes while possessing the thermal stability and high reliability characteristics of PN epitaxial diodes. Super Barrier Rectifier (SBR) diode is designed for high power, low loss and fast switching...

5. What is the difference between SBR and Ultra Fast rectifiers? SBR has switching speed and other characteristics comparable to that of an ultrafast rectifier with the added benefit of having a forward voltage (VF) that is 20 to 25% lower. This reduced VF can lead to a substantial reduction in power savings and efficiency. 6. How fast is the TRR of an SBR? A SBR has a TRR comparable Schottky and Ultra Fast rectifiers. For 150V and higher SBR device to Schottky), minority carriers injected in the drift region, slightly slower but softer recovery. >30V – 150V Schottky Diodes Lower VF, fast lower...
