Diodes Incorporated SBR3U60P5-13

Overview

SBR3U60P5-13 from Diodes Incorporated is a 3A, 60V Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring 0.60 V max forward voltage at 3.0 A and 25°C, 0.06 mA max reverse leakage at 60 V and 25°C, and qualified to AEC-Q101 for automotive-grade reliability. It serves as a freewheeling or reverse protection diode in DC/DC converters and power supplies operating up to +175°C junction temperature.

For engineers reviewing the SBR3U60P5-13 datasheet, SBR3U60P5-13 pinout, SBR3U60P5-13 application, or SBR3U60P5-13 equivalent, key selection criteria include high-temperature reverse leakage performance, low VF stability across temperature, avalanche energy rating (120 mJ), and thermal resistance (35 °C/W on Al board) for compact power-stage designs.

Technical Context

This SBR device uses patented Super Barrier Rectifier technology to deliver Schottky-like forward conduction with enhanced ruggedness-specifically superior avalanche capability versus standard Schottky diodes. Its structure enables stable 0.52 V VF at 3.0 A and +125°C while maintaining only 2.7 µA IR at 60 V and +125°C.

The PowerDI5 package provides dual thermal paths: 95 °C/W (FR-4 PCB, 2 oz Cu) and 35 °C/W (2"×2" Al board), enabling efficient heat dissipation in space-constrained industrial and automotive power stages. The device's 110 pF junction capacitance at 4 V supports moderate-frequency switching applications without excessive AC losses.

Manufacturer

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

The SBR® product line delivers high-current, low-VF rectification with robust avalanche capability-designed specifically for demanding power conversion stages where Schottky limitations (leakage, temperature instability) and standard PN diode losses are unacceptable.

FAQ

What is the maximum junction temperature and how does it affect derating?

The SBR3U60P5-13 has a rated junction temperature range of −55°C to +175°C. At ambient temperatures above +75°C, its average forward current must be linearly derated from 3.0 A to zero at +175°C (per Figure 4). This allows full-rated operation in under-hood automotive environments where board-level temperatures reach +125°C.

How does the PowerDI5 package improve thermal performance compared to SMA or SMB?

The PowerDI5 package features an exposed copper thermal pad on the bottom side, enabling direct thermal coupling to PCB copper pours or heatsinks. Its RθJC of 15°C/W and RθJA of 35°C/W on aluminum board significantly outperform SMA (RθJA ≈ 120°C/W) and SMB (RθJA ≈ 90°C/W), reducing junction temperature rise by up to 50°C at 3A continuous load.

Is the SBR3U60P5-13 suitable for synchronous rectification replacement?

No-it is a unidirectional, passive rectifier and cannot replace active synchronous rectifier MOSFETs. While its low VF (0.60 V) reduces conduction loss, it lacks gate control and cannot be turned off. It is appropriate for non-synchronous topologies like flyback or boost where passive rectification is specified.

What is the significance of the "SBR®" trademark and how does it differ from Schottky?

SBR® (Super Barrier Rectifier) is Diodes Incorporated's patented structure combining Schottky-like low VF with PN-junction ruggedness. Unlike Schottky diodes, SBR devices exhibit superior avalanche energy handling (120 mJ vs. typically <20 mJ), lower high-temperature leakage, and no soft recovery-making them more reliable in inductive switching and automotive environments.
