Diodes Incorporated SBR3060CTFP

Overview

SBR3060CTFP from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 60V peak repetitive reverse voltage, with typical forward voltage of 0.65V at 15A and 125°C, and 200A non-repetitive surge capability-designed for high-efficiency AC/DC secondary-side rectification in server power supplies.

For engineers reviewing the SBR3060CTFP datasheet, SBR3060CTFP pinout, SBR3060CTFP application, or SBR3060CTFP equivalent, key selection criteria include low VF stability over temperature, soft switching behavior to reduce EMI in synchronous rectifier replacements, and ITO-220AB isolation rating for heatsink-mounted designs requiring 2000VAC terminal-to-heatsink isolation.

Technical Context

This dual-element rectifier integrates two independent 30A-rated super barrier diodes sharing a common cathode terminal, enabling center-tapped transformer or dual-output DC/DC converter topologies. Its patented super barrier structure replaces traditional Schottky architecture to deliver lower leakage than standard Schottkys while maintaining near-Schottky forward voltage.

The device operates across –65°C to +150°C junction temperature range with 4°C/W thermal resistance (junction-to-case, per leg), and exhibits soft reverse recovery with no stored charge tail-critical for reducing switching losses and voltage overshoot in high-frequency flyback and LLC resonant converters.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current super barrier rectifier applications.

Compared with VS-30CPH06-M3, SBR3060CTFP trades off slightly higher thermal resistance for integrated 2000VAC isolation and softer switching-making it preferable in compact, isolated, high-frequency power supplies. Against MBR3060CT, it delivers measurable VF reduction and leakage suppression at elevated temperature, directly improving efficiency and reliability in thermally demanding deployments.

SBR3060CTFP is available at Aetrix Electronics and suitable for server power supply secondary rectification, industrial DC/DC converter output stages, and telecom rectifier modules requiring stable component supply, long-lifecycle support, and RoHS-compliant packaging.

Supply support for SBR3060CTFP includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

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 North America.

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 datacenter, telecom, and industrial power supplies where VF stability and soft switching are critical.

FAQ

What is the difference between SBR3060CTFP and SBR3060CT?

The SBR3060CTFP uses the ITO-220AB package with electrically isolated metal tab rated for 2000VAC terminal-to-heatsink isolation, while the SBR3060CT uses standard TO-220AB with non-isolated tab. Both share identical electrical specs, but only the ITO-220AB version allows direct heatsink mounting in isolated topologies without insulating hardware.

Can SBR3060CTFP be used as a drop-in replacement for standard Schottky rectifiers?

Yes-its pinout matches industry-standard dual common-cathode TO-220/ITO-220 packages, and its 60V VRRM and 30A total rating align with parts like MBR3060CT. However, its lower VF and near-zero Qrr improve efficiency and EMI performance, especially above 100kHz switching frequencies where Schottky reverse recovery becomes problematic.

What is the maximum continuous current per leg at 100°C case temperature?

Per the derating curve in DS30969 Rev. 6-2, the maximum average forward current per leg drops to approximately 12.5A at TC = 100°C. This reflects thermal limits-not electrical limits-and assumes adequate heatsinking to maintain that case temperature under steady-state operation.

Does SBR3060CTFP require a thermal pad or insulator when mounted to a heatsink?

No-the ITO-220AB package provides built-in 2000VAC isolation between all terminals and the metal tab, eliminating the need for mica pads, silicone insulators, or isolated mounting hardware. This simplifies mechanical assembly and improves thermal interface consistency in production environments.
