Diodes Incorporated SBR10B45P5-7D

Overview

SBR10B45P5-7D from Diodes Incorporated is a 10A, 45V advanced super barrier rectifier in the POWERDI5 package, featuring ultra-low 0.55V max forward voltage at 10A/25°C, 0.38mA max reverse leakage at 45V/25°C, and thermal resistance of 93°C/W (junction-to-ambient). It serves as a high-efficiency freewheeling or polarity protection diode in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBR10B45P5-7D datasheet, SBR10B45P5-7D pinout, SBR10B45P5-7D application, or SBR10B45P5-7D equivalent, key selection criteria include forward voltage drop at high current, reverse leakage stability up to +150°C, thermal performance in thin-profile layouts, and RoHS-compliant green packaging with 1.1mm profile.

Technical Context

This super barrier rectifier uses proprietary epitaxial structure to achieve lower VF than standard Schottky diodes while maintaining superior IR stability at elevated temperatures-critical for high-density power supplies where thermal derating impacts reliability. Its 140A non-repetitive surge rating supports transient load handling in switching converters.

The POWERDI5 package provides low RθJC (10°C/W) and optimized copper clip construction for enhanced current spreading and reduced thermal impedance versus SOD-123 or SMA packages. Device operates across -55°C to +150°C with ESD ratings of 8kV HBM and 400V MM.

FAQ

What is the maximum junction temperature for continuous operation?

The SBR10B45P5-7D has an operating junction temperature range of -55°C to +150°C. For continuous operation at rated 10A current, thermal design must ensure TJ does not exceed +150°C-achievable with proper PCB copper area and ambient control per the derating curve in Figure 4 of DS38177.

Is the POWERDI5 package lead-free and RoHS compliant?

Yes. The SBR10B45P5-7D features a lead-free finish and meets EU RoHS Directive 2011/65/EU requirements. It is also halogen- and antimony-free ("Green" per Diodes' definition), containing <900ppm bromine, <900ppm chlorine, and <1000ppm antimony compounds.

How does its reverse leakage compare to standard Schottky diodes at high temperature?

At +125°C and VR = 45V, the SBR10B45P5-7D exhibits ≤1.2mA IR-significantly lower than typical 45V Schottky diodes (often >5mA at same conditions). This stability is achieved through super barrier architecture, preventing thermal runaway in sealed or high-ambient environments.

Can it be used in place of a 40V Schottky diode in a 36V system?

Yes-its 45V VRRM provides 9V margin above 36V nominal rails, satisfying IEC/UL creepage and surge requirements. However, verify layout clearance and transient clamping behavior, as super barrier devices exhibit slightly different capacitance (CT ≈ 1200pF at 0V) versus Schottky counterparts.
