Diodes Incorporated SBRT20U60SP5-13

Overview

SBRT20U60SP5-13 from Diodes Incorporated is a 20A, 60V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 surface-mount package. It delivers ultra-low forward voltage (0.48 V at 20 A, +25°C), low reverse leakage (0.4 mA at 60 V, +25°C), and thermal resistance of 2 °C/W junction-to-lead - optimized for high-efficiency rectification in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBRT20U60SP5-13 datasheet, SBRT20U60SP5-13 pinout, SBRT20U60SP5-13 application, or SBRT20U60SP5-13 equivalent, key selection criteria include forward voltage drop at full load, high-temperature reverse leakage stability, thermal performance in constrained PCB layouts, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This TrenchSBR device uses advanced trench-based super barrier technology to achieve lower VF than conventional Schottky diodes while maintaining superior IR stability at elevated temperatures (≤80 µA at 60 V, +125°C). Its structure suppresses minority-carrier injection, enabling fast recovery without soft-recovery tail current.

The POWERDI®5 package integrates a thermally enhanced leadframe with low-profile (1.1 mm max) molded plastic housing rated UL 94V-0. With RθJL = 2 °C/W and RθJA = 11 °C/W (on 50 mm × 50 mm × 23 mm heatsinked 2 oz. PCB), it supports continuous 20 A operation under controlled ambient conditions.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous current rating for SBRT20U60SP5-13 at +100°C ambient?

At TA = +100°C with recommended PCB layout (2 oz. copper, 50 mm × 50 mm heatsink), the device supports 13.5 A average rectified current per Figure 5 derating curve. This reflects thermal limits imposed by RθJA = 11 °C/W and TJ(max) = +150°C, not electrical degradation.

Does SBRT20U60SP5-13 have a soft recovery characteristic?

No - it exhibits fast, non-soft recovery due to its majority-carrier TrenchSBR structure. Reverse recovery time is not specified because there is negligible stored charge; measured trr is <25 ns under IF = 10 A, di/dt = 100 A/µs, confirming suitability for high-frequency switching topologies.

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

Yes - SBRT20U60SP5-13 features a lead-free finish and meets EU RoHS Directive 2011/65/EU. It is also halogen- and antimony-free ("Green" per Diodes' definition: Br+Cl <1500 ppm, Sb <1000 ppm), certified UL 94V-0, and moisture sensitivity level 1.

Can SBRT20U60SP5-13 replace a standard Schottky diode in an existing design?

Yes - it is a direct drop-in replacement for 20 A, 60 V Schottkys in POWERDI®5 footprint. Key advantages include lower VF (0.48 V vs. typical 0.7 V) and improved IR stability at high temperature, but layout must maintain the exposed cathode thermal pad per AP02001 guidelines for optimal RθJL.
