Diodes Incorporated SBR8B60P5-7D

Overview

SBR8B60P5-7D from Diodes Incorporated is an 8A Super Barrier Rectifier (SBR®) in a POWERDI®5 package, rated for 60V peak repetitive reverse voltage, with max forward voltage drop of 0.6 V at 8 A and 25°C, and max reverse leakage current of 0.22 mA at 60 V and 25°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 SBR8B60P5-7D datasheet, SBR8B60P5-7D pinout, SBR8B60P5-7D application, or SBR8B60P5-7D equivalent, key selection criteria include ultra-low VF for reduced conduction loss, stable IR up to +125°C, thermal resistance (RθJC = 3°C/W), low-profile 1.1 mm height, and RoHS-compliant green packaging.

Technical Context

This SBR rectifier employs patented Super Barrier technology-distinct from Schottky and standard PN junctions-to deliver superior avalanche ruggedness while maintaining low VF and low IR. Its structure enables higher surge current tolerance (IFSM = 170 A, 8.3 ms) and stable reverse leakage across temperature.

The POWERDI®5 package integrates a thermally efficient copper heat sink on the bottom side, requiring PCB-level connection of left and right pins for optimal thermal path. Junction-to-case thermal resistance is 3°C/W, enabling high-power-density designs without external heatsinking in many applications.

Manufacturer

Diodes Incorporated is a global semiconductor company specializing in discrete, analog, and mixed-signal solutions, with design centers in Asia, Europe, and the U.S., and manufacturing in Taiwan and China.

The SBR® product line targets high-efficiency power conversion applications where Schottky limitations-poor high-temperature leakage and low avalanche capability-compromise reliability in compact, thermally constrained designs.

FAQ

What is the maximum continuous forward current rating for SBR8B60P5-7D?

The SBR8B60P5-7D is rated for 5 A average forward current (IO) at TA = +25°C. This rating decreases with rising ambient temperature-derating to approximately 3.5 A at +85°C and 2.2 A at +125°C per Figure 4 in DS38284 Rev. 3-2. The device can handle 8 A peak forward current for short durations, provided thermal limits are observed.

How should the POWERDI®5 thermal pad be implemented on the PCB?

The exposed copper pad on the bottom side must be soldered to a dedicated thermal land on the PCB, connected via ≥2 thermal vias (0.3 mm diameter, filled or capped) to an internal ground or power plane. Recommended pad size matches the D2 (3.054 mm) and E2 (3.549 mm) dimensions per AP02001. Avoid solder mask over the pad to ensure low RθJA.

Is SBR8B60P5-7D suitable for automotive applications?

SBR8B60P5-7D operates from –55°C to +150°C and meets AEC-Q101 stress test requirements for discrete diodes when qualified per Diodes Incorporated's automotive-grade variants (e.g., SBR8B60P5Q-7D). The standard SBR8B60P5-7D is not AEC-Q101 certified and is intended for industrial and commercial power applications.

What does the "7D" suffix indicate in the part number?

The "7D" suffix denotes tape-and-reel packaging: 1,500 units per reel on a 7-inch diameter reel using 12 mm wide carrier tape. This differs from "7" (same quantity, same reel size, but unspecified tape width) and "13D" (5,000 units on 13-inch reel with 12 mm tape). All variants share identical electrical and thermal specifications.
