Diodes Incorporated SBRT20U60SP5-7D

Overview

SBRT20U60SP5-7D from Diodes Incorporated is a 20A, 60V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 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. It serves as a high-efficiency rectifier or freewheeling diode in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBRT20U60SP5-7D datasheet, SBRT20U60SP5-7D pinout, SBRT20U60SP5-7D application, or SBRT20U60SP5-7D equivalent, key selection criteria include thermal resistance (RθJL = 2°C/W), low-profile 1.1mm height, RoHS/Green compliance, and high-temperature IR stability up to +150°C.

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 reverse leakage performance. Its RθJL of 2°C/W enables efficient heat transfer to PCB copper, supporting high-current operation without external heatsinks in constrained layouts.

The POWERDI®5 package integrates a thermally optimized leadframe with molded green compound (UL 94V-0), delivering mechanical robustness and moisture sensitivity level 1. The device operates across –55°C to +150°C, with validated performance at 125°C junction temperature per electrical characterization.

FAQ

What is the maximum junction temperature for continuous operation?

The SBRT20U60SP5-7D is rated for continuous operation up to +150°C junction temperature, with electrical characteristics fully characterized at that temperature. Derating curves confirm usable current down to ~8A at 125°C ambient with heatsink, and thermal resistance data supports safe operation within this range when PCB copper area meets recommended layout guidelines.

Is the POWERDI®5 package lead-free and RoHS compliant?

Yes. The SBRT20U60SP5-7D features a lead-free finish and complies with EU RoHS Directive 2011/65/EU. It is also halogen- and antimony-free ("Green" per Diodes' definition), containing <900ppm bromine, <900ppm chlorine, and <1000ppm antimony compounds, verified per JEDEC J-STD-020 moisture sensitivity Level 1.

How does its reverse leakage compare to standard Schottky diodes at elevated temperature?

At 60V reverse bias and +125°C, SBRT20U60SP5-7D exhibits ≤0.1mA IR-up to 10× lower than typical Schottky diodes of similar rating. This stability stems from its trench super barrier structure, which suppresses thermionic emission more effectively than planar Schottky junctions, preserving efficiency in hot environments like enclosed power supplies.

Can it replace a standard 20A Schottky in an existing design without layout changes?

Yes, provided the PCB pad layout matches the POWERDI®5 footprint (AP02001 recommended) and thermal copper area is ≥50mm² of 2-oz copper. Electrical substitution is direct: same pinout, voltage rating, and current capability. No schematic change is needed, but verify thermal performance under worst-case load since VF is lower, potentially altering conduction loss distribution.
