Diodes Incorporated SBR05M60BLP-7

Overview

SBR05M60BLP-7 from Diodes Incorporated is a 0.5A, 60V full-bridge Super Barrier Rectifier in a U-DFN3030-4 package, integrating four diodes with VF ≤ 0.49 V at 0.5A and IR ≤ 0.10 mA at 60V and +25°C. It delivers low forward voltage drop, high-temperature stability up to +150°C, and is designed for space-constrained AC/DC front-end rectification in compact power supplies.

For engineers reviewing the SBR05M60BLP-7 datasheet, SBR05M60BLP-7 pinout, SBR05M60BLP-7 application, or SBR05M60BLP-7 equivalent, key selection criteria include its 60V reverse voltage rating, 0.5A average output current capability, U-DFN3030-4 thermal performance (RθJA = 215°C/W), and suitability for low-profile bridge rectification in USB-C PD adapters and IoT power modules.

Technical Context

This device implements patented Super Barrier Rectifier (SBR®) technology to achieve lower VF and higher temperature stability than standard Schottky or PN junction bridges. Its monolithic full-bridge topology eliminates discrete interconnect losses and enables direct PCB-level integration without external wiring.

The U-DFN3030-4 package features NiPdAu-plated copper lead frame terminals and a thermally optimized 3.0×3.0 mm footprint with exposed thermal pad (DNC pad not connected). Electrical behavior is characterized across -55°C to +150°C, with IR rising to 20 µA at +125°C under 60V reverse bias.

FAQ

What is the maximum continuous current rating for SBR05M60BLP-7?

The SBR05M60BLP-7 is rated for 0.5 A average rectified output current (IO) at TA = +25°C with proper PCB copper area. Derating is required above +25°C ambient: at +85°C, IO drops to ~0.35 A per the Fig. 4 derating curve. This rating assumes use of the recommended U-DFN3030-4 pad layout with 2 oz. copper and thermal vias.

Is the DNC pad on the bottom of the U-DFN3030-4 package electrically connected?

No, the center thermal pad labeled "DNC" (Do Not Connect) is electrically isolated and must remain unconnected to any net. It serves only as a mechanical anchor and thermal mass for reflow soldering. Connecting it risks shorting internal junctions or compromising isolation integrity between AC and DC sides of the bridge.

How does SBR05M60BLP-7 compare to standard Schottky bridge rectifiers in thermal performance?

SBR05M60BLP-7 achieves lower junction temperature rise than comparable Schottky bridges due to its 0.49 V VF (vs. typical 0.55–0.65 V), reducing power dissipation by ~120 mW at 0.5A. Combined with the U-DFN3030-4's low RθJA of 215°C/W and optimized pad layout, this yields ~10°C lower TJ at steady state versus SDM0560LP-7 under identical conditions.

Can SBR05M60BLP-7 be used in capacitance-input filter configurations?

Yes, but with 20% current derating as specified in the Absolute Maximum Ratings table. For example, with a 60 Hz capacitive input filter, the average forward current must be limited to 0.4 A instead of 0.5 A to prevent surge-related degradation. This accounts for peak current stress during capacitor charging cycles.
