Diodes Incorporated SBR2065D1-13

Overview

SBR2065D1-13 from Diodes Incorporated is a 20A, 65V Super Barrier Rectifier in TO252 (DPAK) package, featuring 0.63V max forward voltage at 20A/25°C and 0.4mA max reverse leakage at 65V/125°C. It delivers low conduction loss and stable high-temperature leakage for DC-DC output rectification in automotive power supplies and industrial SMPS.

For engineers reviewing the SBR2065D1-13 datasheet, SBR2065D1-13 pinout, SBR2065D1-13 application, or SBR2065D1-13 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (RθJC = 1.7°C/W), reverse leakage at elevated temperature, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This Super Barrier Rectifier uses patented SBR® technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability. Its 65V VRRM rating supports 48V system bus rectification with margin, and its 140A non-repetitive surge capability handles transient load dumps.

The device operates from –55°C to +150°C, with RθJA = 11°C/W on a 2"×2" aluminum board + heatsink. Junction capacitance is 1000pF at 1V reverse bias (f = 1MHz), supporting moderate-frequency switching applications up to ~500kHz.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, specializing in high-efficiency power solutions, signal integrity products, and protection devices for automotive, industrial, and consumer markets.

The SBR® Super Barrier Rectifier product line was developed to replace conventional Schottky and fast recovery diodes in high-current, high-temperature applications where low VF and stable IR are simultaneously required-particularly in automotive 12V/48V systems and industrial power supplies.

FAQ

What is the maximum junction temperature and how is it maintained?

The SBR2065D1-13 has an operating junction temperature range of –55°C to +150°C. Maintaining TJ ≤ 150°C requires proper thermal design: the device's RθJC of 1.7°C/W demands soldering the exposed cathode pad to ≥100 mm² of 2 oz copper with thermal vias to internal planes. At 20A, junction rise above case is ~34°C-so case temperature must stay ≤116°C for safe operation.

Is this part suitable for synchronous rectification circuits?

No-SBR2065D1-13 is a unidirectional, passive rectifier and cannot be actively controlled like a MOSFET-based synchronous rectifier. It functions as a freewheeling or output rectifier in non-synchronous topologies (e.g., flyback, forward, half-bridge). For synchronous designs, discrete N-channel MOSFETs with gate drivers are required.

How does its reverse leakage compare to standard Schottky diodes at 125°C?

At VR = 65V and TJ = 125°C, SBR2065D1-13 exhibits ≤0.4mA IR-up to 10× lower than typical 60V Schottky diodes (which often exceed 3–5mA under identical conditions). This is due to its super barrier structure, which suppresses thermionic emission more effectively than metal-semiconductor junctions, directly enhancing thermal stability.

Can it replace a standard 60V Schottky in existing PCB layouts?

Yes-the SBR2065D1-13 uses the industry-standard TO252 (DPAK) footprint and pinout (anode/cathode/exposed cathode pad), matching common 60V Schottky rectifiers like MBR2060CT. No layout change is needed, but verify that the 65V VRRM meets your system's transient voltage margin requirements and that thermal relief pads accommodate the same solder stencil.
