Diodes Incorporated SBRT60U60CT

Overview

SBRT60U60CT from Diodes Incorporated is a 60A dual common-cathode Trench Super Barrier Rectifier (SBR) in TO-220AB package, rated for 60V peak repetitive reverse voltage, with max 0.62V forward voltage at 30A/25°C and 0.18mA reverse leakage at 60V/25°C. It serves as high-efficiency output rectifier or freewheel diode in high-density DC-DC converters and AC-DC adapters.

For engineers reviewing the SBRT60U60CT datasheet, SBRT60U60CT pinout, SBRT60U60CT application, or SBRT60U60CT equivalent, key selection criteria include ultra-low VF stability across temperature, low thermal resistance (1°C/W), tight IR control up to +125°C, and TO-220AB mechanical compatibility with standard heatsinks.

Technical Context

This dual-leg SBR uses trench-based super barrier technology to achieve lower forward voltage than Schottky diodes while maintaining superior high-temperature reverse leakage performance versus conventional PN junction rectifiers. Its common-cathode configuration supports synchronous rectification topologies requiring matched dual diodes sharing a single cathode node.

The device operates within -55°C to +150°C junction temperature range, with thermal resistance of 1°C/W (junction-to-case) when mounted on an aluminum heatsink (50mm × 50mm × 23mm). Derating curves confirm 30A average current capability at +50°C ambient and 15A at +100°C ambient.

FAQ

Is SBRT60U60CT RoHS and halogen-free compliant?

Yes. SBRT60U60CT meets EU RoHS 2 Directive 2011/65/EU and is certified halogen- and antimony-free: bromine and chlorine each <900ppm, total Br+Cl <1500ppm, antimony <1000ppm. The matte tin finish and green molding compound comply with Diodes Incorporated's "Green" definition.

What is the thermal resistance from junction to case, and how is it measured?

RθJC is 1°C/W per leg, measured with the device mounted on a 50mm × 50mm × 23mm aluminum heatsink per Note 5 in the datasheet. This value assumes full contact between the isolated metal tab and heatsink surface using thermal interface material; actual system RθJA depends on heatsink size and airflow.

Can SBRT60U60CT replace standard Schottky diodes like MBR6060CT in existing designs?

Yes, with benefits: SBRT60U60CT offers lower VF (0.62V vs. 0.75V) and dramatically lower IR at high temperature (50µA vs. 1.5mA at 125°C). However, verify PCB footprint compatibility (TO-220AB vs. TO-220AC), tab isolation requirements, and thermal layout-no circuit redesign is needed.

Does the metal tab connect to a specific pin, and is it electrically isolated?

Yes-the metal tab is internally connected to Pin 2 (common cathode) and is electrically isolated from the leads. When mounted to a heatsink, the heatsink becomes part of the cathode net; ensure proper insulation if the heatsink is grounded or at a different potential.
