Diodes Incorporated SBRT20U60SP5-7

Overview

SBRT20U60SP5-7 from Diodes Incorporated is a 20A, 60V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 surface-mount package, featuring ultra-low 0.48V forward voltage at 20A/25°C, 0.4mA max reverse leakage at 60V/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency output rectifier or freewheeling diode in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBRT20U60SP5-7 datasheet, SBRT20U60SP5-7 pinout, SBRT20U60SP5-7 application, or SBRT20U60SP5-7 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJL = 2°C/W), reverse leakage stability up to +150°C, and compatibility with thin-profile (<1.1mm) PCB layouts in space-constrained power supplies.

Technical Context

This TrenchSBR device uses proprietary trench-based super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability-unlike conventional Schottkys, it sustains <0.4mA leakage at 60V and +125°C. Its RθJL of 2°C/W enables efficient heat transfer to the PCB copper, supporting continuous 20A operation with appropriate heatsinking.

The POWERDI®5 package integrates a low-inductance, dual-source terminal structure optimized for high-frequency switching topologies. With a 1.1mm profile and 0.093g mass, it meets mechanical constraints for ultra-thin consumer and automotive power modules requiring AEC-Q101 compliance.

Key Specifications

Pinout & Package

The SBRT20U60SP5-7 uses the POWERDI®5 package: a 3-terminal, single-row surface-mount outline with exposed thermal pad (cathode-connected), 1.1mm height, and 6.5mm × 4.0mm footprint. Terminals are anode (pin 1), cathode (pin 2), and cathode thermal pad (pin 3, internally tied to pin 2).

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.

Compared with SBRT20U60SP5-13, the -7 variant offers identical electrical performance with smaller reel logistics; versus SBRT15U60SP5-7, the -7 provides 33% higher current capacity at the cost of slightly higher conduction loss at partial load-critical for 20A-rated power stages.

FAQ

What is the thermal pad connection requirement for SBRT20U60SP5-7?

The exposed thermal pad (Pin 3) is internally connected to the cathode (Pin 2). It must be soldered to a minimum 25 mm² copper pour tied to the cathode net. This establishes the 2°C/W RθJL path; omitting the pad connection raises junction temperature by >40°C at 20A.

Does SBRT20U60SP5-7 support reflow soldering per J-STD-020?

Yes-it is rated Moisture Sensitivity Level 1 and qualified for standard Pb-free reflow profiles (peak 260°C, 20–40 sec). The green molding compound withstands repeated thermal cycles without delamination, and the 1.1mm profile prevents tombstoning on fine-pitch pads.

How does SBRT20U60SP5-7 compare to standard Schottky diodes at 125°C?

At 60V reverse bias and +125°C, SBRT20U60SP5-7 exhibits only 80µA leakage-up to 10× lower than typical 60V Schottkys (0.5–1.0mA). This eliminates thermal runaway risk in sealed, high-ambient environments where IR-induced self-heating would otherwise escalate.

Can SBRT20U60SP5-7 replace a 60V, 20A through-hole diode in existing designs?

Yes, with PCB layout revision: the POWERDI®5 footprint (6.5mm × 4.0mm) replaces TO-220 or D²PAK outlines. Its 1.1mm height enables vertical stacking in multi-rail supplies, and the 2°C/W RθJL often eliminates the need for a heatsink required by through-hole equivalents.
