Diodes Incorporated SBR8E45P5-13D

Overview

SBR8E45P5-13D from Diodes Incorporated is a 45 V, 5 A Super Barrier Rectifier (SBR®) in the POWERDI®5 surface-mount package, featuring ultra-low 0.6 V max forward voltage at 5 A and only 0.28 mA max reverse leakage at 45 V/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 SBR8E45P5-13D datasheet, SBR8E45P5-13D pinout, SBR8E45P5-13D application, or SBR8E45P5-13D equivalent, key selection criteria include thermal resistance (RθJA = 90 °C/W), junction-to-case thermal performance (RθJC = 8 °C/W), high-temperature IR stability (75 µA at 125°C), low-profile 1.1 mm height, and RoHS-compliant green packaging.

Technical Context

This SBR rectifier employs proprietary super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature reverse leakage control-critical for thermally constrained power supplies. Its 120 A non-repetitive surge rating supports robust transient handling in switching converter outputs.

The POWERDI®5 package integrates a bottom-side heat sink with dual anode/cathode terminals electrically connected on PCB, enabling efficient thermal conduction to copper planes. ESD ratings of 8 kV HBM and 400 V MM reflect enhanced manufacturability in automated assembly environments.

Key Specifications

Pinout & Package

Packaged in the POWERDI®5 thermally enhanced surface-mount outline (3.966 mm × 6.504 mm × 1.1 mm), this device features a bottom-side exposed thermal pad and two terminals: left pin (anode) and right pin (cathode), both requiring PCB-level connection per marking diagram.

FAQ

What is the maximum operating junction temperature for SBR8E45P5-13D?

The device is rated for TJ from –55°C to +150°C. At 150°C, its IR increases to 75 µA at 45 V, and IO derates to approximately 2.2 A per Figure 4. Thermal design must ensure junction temperature remains within this limit under worst-case ambient and power dissipation conditions.

Is SBR8E45P5-13D pin-compatible with standard SOD-123 or SMA packages?

No. It uses the proprietary POWERDI®5 package with a 1.84 mm pin pitch and bottom thermal pad. The footprint differs significantly from SOD-123 (2.5 mm pitch) and SMA (4.5 mm length); PCB layout must follow AP02001 recommended pad dimensions and stencil design.

Can SBR8E45P5-13D replace a standard Schottky diode in an existing design?

Yes-if VRRM (45 V) and IO (5 A) meet requirements and the PCB supports POWERDI®5 mounting. Its lower VF reduces conduction loss, but verify thermal relief on the cathode pad and confirm no layout interference with the 1.1 mm profile and bottom-sink geometry.

Does SBR8E45P5-13D require a heatsink for 5 A operation?

Not necessarily: with adequate 2 oz. copper thermal land (≥100 mm²) and airflow, RθJA = 90 °C/W yields ~45°C rise at 5 A (PD ≈ 3 W). For sealed enclosures or >85°C ambient, additional copper or localized heatsinking is recommended to maintain TJ < 125°C.
