Diodes Incorporated SBR8U60P5-7

Overview

SBR8U60P5 from Diodes Incorporated is an 8A ultra-low forward voltage Super Barrier Rectifier in POWERDI5 package, rated for 60V peak reverse voltage and 150°C junction operation. It delivers VF = 0.35V at 8A/25°C and IR ≤ 0.12mA at 60V/25°C, enabling high-efficiency DC-DC output rectification in compact power supplies.

For engineers reviewing the SBR8U60P5 datasheet, SBR8U60P5 pinout, SBR8U60P5 application, or SBR8U60P5 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJS = 3°C/W), surge current rating (IFSM = 280A), and compatibility with high-temperature PCB layouts using cathode-tab thermal sinking.

Technical Context

This Super Barrier Rectifier uses patented Schottky-like barrier technology with enhanced soft-recovery characteristics, eliminating hard reverse-recovery spikes common in standard Schottkys. Its low Qrr and soft switching behavior reduce EMI in high-frequency SMPS outputs.

The device integrates a monolithic copper leadframe with direct die-to-cathode-tab thermal path, enabling efficient heat transfer to PCB copper pour. Its POWERDI5 package supports bottom-side thermal sinking via the exposed cathode pad, critical for maintaining TJ ≤ 150°C under sustained 8A conduction.

FAQ

What is the thermal interface requirement for optimal RθJS performance?

The SBR8U60P5 achieves its specified RθJS = 3°C/W only when the entire bottom-side cathode tab is soldered to a ≥25 mm², 2 oz copper pour with thermal vias to inner ground planes. Minimum pad dimensions per AP02001 are 3.05 mm × 5.30 mm. Using smaller pads or insufficient copper raises RθJS to >6°C/W.

Can this device replace a standard Schottky diode in an existing design?

Yes - it is a direct footprint-compatible replacement for POWERDI5-packaged Schottkys (e.g., SBM860P5), offering lower VF and superior thermal performance. However, verify that the PCB layout provides adequate cathode-side copper area and that the reduced VF does not cause overvoltage during transient load steps due to faster current rise.

Is the SBR8U60P5 suitable for reverse polarity protection?

No - it is optimized as a forward-conducting rectifier, not a protection switch. Its 60V VRRM is insufficient for 24V/48V bus protection, and its soft recovery lacks the controlled turn-off needed for active OR-ing. Use dedicated ideal diode controllers (e.g., DIODES AP22802) instead.

Does the "P5" suffix indicate a specific process or qualification level?

Yes - "P5" denotes Diodes' proprietary Super Barrier Rectifier process using a graded barrier structure on epitaxial silicon, qualified to AEC-Q101 for automotive applications and rated for 150°C continuous operation. It is not a screening level but a fundamental process and material designation.
