Diodes Incorporated SBR10E45P5-7D

Overview

SBR10E45P5 from Diodes Incorporated is a 10A, 45V Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring ultra-low 0.47V max forward voltage at 10A/25°C and only 0.28mA max reverse leakage at 45V/125°C. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBR10E45P5 datasheet, SBR10E45P5 pinout, SBR10E45P5 application, or SBR10E45P5 equivalent, key selection criteria include forward voltage drop at full load, high-temperature reverse leakage stability, thermal resistance (RθJA = 88°C/W), junction-to-case thermal path (RθJC = 14°C/W), and compatibility with thin-profile (<1.1mm) power designs.

Technical Context

This SBR uses patented Super Barrier Rectifier technology to achieve Schottky-like low VF without the high IR trade-off typical of conventional Schottky diodes. Its structure enables stable 0.05mA IR at 45V/25°C and 0.28mA at 45V/125°C - critical for thermally constrained power stages.

The PowerDI5 package provides low-profile mounting (1.1mm max height), 0.093g mass, and optimized thermal conduction via copper leadframe with matte tin terminals. It supports 275A non-repetitive surge current and operates from –55°C to +150°C junction temperature.

FAQ

What is the maximum junction temperature rating for SBR10E45P5?

The SBR10E45P5 has a specified operating junction temperature range of –55°C to +150°C. This rating is validated per the datasheet's Absolute Maximum Ratings table and supported by thermal characterization data including RθJA = 88°C/W and RθJC = 14°C/W. Derating curves in Figure 4 confirm 10A operation is sustainable up to 125°C case temperature with appropriate PCB copper area.

Is SBR10E45P5 suitable for automotive applications?

The SBR10E45P5 is not AEC-Q101 qualified out-of-the-box but is manufactured in IATF 16949 certified facilities and supports automotive change control upon request. Diodes states that parts qualified to AEC-Q100/101/200 and PPAP-capable versions are available - customers must contact Diodes or their local representative to initiate qualification for specific automotive programs.

How does the PowerDI5 package compare thermally to TO-252 (DPAK)?

The PowerDI5 package offers lower profile (1.1mm vs. ~2.4mm for DPAK) and improved thermal performance due to its exposed cathode pad directly soldered to PCB copper. With RθJC = 14°C/W, it achieves better junction-to-board conduction than standard DPAK packages (typically RθJC ≈ 20–25°C/W), enabling higher power density in space-limited designs without compromising thermal safety.

What is the ESD robustness of SBR10E45P5?

The SBR10E45P5 is rated for 8kV Human Body Model (HBM) and 400V Machine Model (MM) ESD protection per JEDEC standards. These values are measured and documented in the "Maximum Ratings" section of the datasheet (DS37867 Rev. 6-2). No external ESD protection is required during board assembly if standard IPC/JEDEC handling protocols are followed.
