Diodes Incorporated SBR8B60P5-7

Overview

SBR8B60P5-7 from Diodes Incorporated is an 8A Super Barrier Rectifier (SBR®) in the POWERDI®5 package, rated for 60V peak repetitive reverse voltage, with a maximum forward voltage of 0.6 V at 8 A and 25°C, and reverse leakage current ≤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 SBR8B60P5-7 datasheet, SBR8B60P5-7 pinout, SBR8B60P5-7 application, or SBR8B60P5-7 equivalent, key selection criteria include ultra-low VF stability across temperature, low IR at 125°C, thermal resistance (RθJC = 3°C/W), rugged avalanche capability versus Schottky diodes, and compatibility with thin-profile PCB layouts requiring <1.1 mm height.

Technical Context

This SBR rectifier uses patented Super Barrier technology to achieve Schottky-like forward conduction while delivering superior avalanche energy handling-critical for reliability in transient-prone power supplies. Its structure enables stable reverse leakage below 50 µA at 125°C and 60 V, unlike conventional Schottkys which degrade rapidly above 85°C.

The POWERDI®5 package integrates a thermally optimized copper leadframe with exposed heat sink on the bottom side, enabling RθJA = 22°C/W on a 2"×2" Al board and supporting continuous 5 A average output current (IO) despite its ultra-thin 1.1 mm profile.

Key Specifications

Pinout & Package

Packaged in the surface-mount POWERDI®5 package (3.966 mm × 6.504 mm × 1.1 mm), featuring an exposed thermal pad on the bottom side and two signal terminals: anode and cathode. Pins are electrically connected to PCB copper pour for thermal and electrical performance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super barrier rectifier applications.

Compared with SBRT8U60P5-7, the SBR8B60P5-7 trades marginal VF increase for significantly better high-temperature IR stability-making it preferable in sealed, thermally constrained adapters. Versus MBR860CT-TP, it delivers 45% lower profile and 45% better thermal resistance, enabling fully surface-mount designs without heatsinks.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

The SBR® product line targets high-efficiency power conversion applications where Schottky limitations-poor high-temperature leakage and low avalanche robustness-require engineered alternatives for reliable, compact, and efficient rectification.

FAQ

What is the maximum junction temperature for continuous operation?

The SBR8B60P5-7 has an operating junction temperature range of –55°C to +150°C. For continuous operation at full 5 A average current, thermal design must ensure TJ does not exceed 150°C-achievable with ≥20 cm² of 2 oz copper on the bottom layer per the RθJA = 22°C/W spec on a 2"×2" Al board.

Is the POWERDI®5 package compatible with standard reflow profiles?

Yes-the POWERDI®5 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity Level 1 and supports standard Pb-free reflow profiles (peak 260°C, 10–30 sec). The green molding compound meets UL 94V-0 flammability rating, and the 0.093 g weight ensures stable placement during SMT assembly.

How does SBR technology differ from Schottky and standard PN rectifiers?

SBR combines a low-barrier metal-semiconductor junction with a tailored epitaxial layer to deliver VF near Schottky levels (0.6 V @ 8 A) while achieving avalanche ruggedness exceeding standard PN rectifiers. Unlike Schottkys, it maintains <50 µA IR at 125°C; unlike PN diodes, it avoids 1.1 V VF penalty and slow reverse recovery.

Can SBR8B60P5-7 replace a 60 V, 8 A Schottky diode directly?

Yes-pin-to-pin compatible in POWERDI®5 footprint-but verify thermal design: its lower VF reduces self-heating, yet its higher surge rating (170 A vs. typical 100 A for Schottkys) may require updated layout for transient current paths. Also confirm system-level leakage budget, as SBR IR is lower at high temperature than most Schottkys.
