Diodes Incorporated SBR8E60P5-7D

Overview

SBR8E60P5-7D from Diodes Incorporated is an 8A, 60V Super Barrier Rectifier (SBR®) in the POWERDI®5 package, featuring ultra-low forward voltage (0.53 V max at 8 A, 25°C), low reverse leakage (0.58 mA max at 60 V, 25°C), and thermal resistance of 92°C/W (J-A). It serves as a high-efficiency rectifier or freewheeling diode in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBR8E60P5-7D datasheet, SBR8E60P5-7D pinout, SBR8E60P5-7D application, or SBR8E60P5-7D equivalent, key selection criteria include forward voltage drop at full load, reverse leakage stability up to +125°C, thermal performance in constrained PCB layouts, and compatibility with thin-profile power supplies requiring <1.1 mm height.

Technical Context

This Super Barrier Rectifier uses a proprietary epitaxial structure to achieve lower VF than standard Schottky diodes while maintaining superior IR stability at elevated temperatures-exhibiting only 100 µA leakage at 60 V and +125°C. Its 9 °C/W junction-to-case thermal resistance enables effective heat transfer to a PCB copper pour via the exposed bottom-side heatsink.

The POWERDI®5 package integrates a thermally optimized leadframe with dual anode/cathode terminals on left/right sides and an electrically connected thermal pad underneath. Pin configuration supports low-inductance layout and minimizes parasitic losses in high-frequency switching applications like synchronous rectification and buck converter outputs.

FAQ

What is the maximum continuous forward current for SBR8E60P5-7D at +100°C ambient?

Per Figure 4 (Forward Current Derating Curve), the device supports approximately 4.5 A continuous forward current at +100°C ambient when mounted on a 1 × MRP FR-4 board with 2 oz copper. This derating ensures junction temperature remains below 150°C under worst-case thermal conditions.

Does SBR8E60P5-7D require a heatsink on the PCB?

No discrete heatsink is required. The POWERDI®5 package's exposed bottom-side thermal pad must be soldered to ≥100 mm² of 2 oz copper on the PCB to achieve the specified RθJA of 92 °C/W. Additional copper area further improves thermal performance but is not mandatory for 8 A operation at 25°C ambient.

How does SBR8E60P5-7D differ from standard Schottky rectifiers?

Unlike conventional Schottky diodes, the SBR® structure delivers lower forward voltage at high current while suppressing reverse leakage drift at elevated temperatures-e.g., 100 µA IR at +125°C versus >10× higher leakage in comparable Schottkys. This eliminates thermal runaway risk in sealed enclosures.

Is SBR8E60P5-7D compatible with lead-free reflow profiles?

Yes. The device is qualified for standard lead-free reflow per J-STD-020, with moisture sensitivity level (MSL) 1-no baking required prior to assembly. Its "Green" molding compound and lead-free terminal finish meet IPC/JEDEC standards for Pb-free manufacturing.
