Diodes Incorporated SBR4060CTFP

Overview

SBR4060CTFP from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier rated for 60V peak reverse voltage, with typical forward voltage of 0.65V at 20A and 125°C, low leakage (<0.5mA at 60V/25°C), and ITO-220AB thermally enhanced package - used in high-efficiency AC/DC front-end rectification for industrial power supplies.

For engineers reviewing the SBR4060CTFP datasheet, SBR4060CTFP pinout, SBR4060CTFP application, or SBR4060CTFP equivalent, key selection criteria include forward voltage at elevated temperature, thermal resistance (RθJC = 4°C/W), surge current rating (280A IFSM), and isolation voltage (2000VAC) for reinforced insulation in off-line SMPS designs.

Technical Context

This dual-diode rectifier integrates two independent 40A-rated Super Barrier diodes in a single ITO-220AB package with common cathode configuration, enabling synchronous or interleaved rectification topologies. Its patented barrier structure delivers lower VF than Schottky diodes while maintaining higher Tj rating (150°C) and superior high-temperature leakage stability.

The device operates under single-phase, half-wave 60Hz resistive/inductive loads, with derating required for capacitive loads (−20% IO). Thermal performance is validated using a specified black aluminum heatsink (37×50×15mm), supporting continuous conduction mode operation up to 20A per leg at 125°C ambient.

Key Specifications

Pinout & Package

Package: ITO-220AB - Thermally optimized variant of TO-220 with isolated tab, UL 94V-0 molded plastic body, matte tin-plated copper leadframe, and 1.65g mass. Tab is electrically isolated from internal circuitry and serves as heatsink interface.

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 the Americas.

The SBR® (Super Barrier Rectifier) product line was developed to replace conventional Schottky and fast recovery diodes in high-efficiency, high-temperature power conversion - targeting industrial, computing, and telecom power systems demanding low VF, high TJ, and stable leakage.

FAQ

What is the maximum junction temperature and how is it validated?

The SBR4060CTFP has a rated maximum junction temperature of +150°C, verified through accelerated life testing and thermal characterization per JESD22-A108. Derating curves in the datasheet (Figure 4) define allowable average forward current versus ambient temperature, assuming use of the specified 37×50×15mm black aluminum heatsink.

Does the ITO-220AB package provide electrical isolation between leads and heatsink?

Yes - the ITO-220AB package features an electrically isolated metal tab, certified for 2000VAC isolation (RMS, 3 seconds) between all terminals and the heatsink-mounting surface. This eliminates the need for mica washers or silicone pads in grounded-chassis applications, reducing thermal resistance by up to 1.2°C/W.

How does SBR4060CTFP compare to standard Schottky rectifiers in high-temperature operation?

Unlike standard Schottky diodes that suffer rapid VF increase and leakage growth above 100°C, the SBR4060CTFP maintains VF = 0.65V and IR ≤ 100mA at 125°C due to its patented super barrier structure - delivering 12–15% lower conduction loss and 10× lower leakage than comparable Schottkys under identical thermal stress.

Is SBR4060CTFP suitable for use in life support equipment?

No - Diodes Incorporated explicitly prohibits use of SBR4060CTFP in life support devices or systems without prior written approval from its CEO. The device is not qualified to ISO 13485 or certified for implantable or critical-care applications per IEC 60601-2-xx standards.
