Diodes Incorporated SBR10U150CTFP

Overview

SBR10U150CTFP from Diodes Incorporated is a 10A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 150V peak reverse voltage, with ultra-low forward voltage (0.63V typ. @ 5A, 25°C) and soft fast switching capability. It serves as a high-efficiency output rectifier in AC/DC power supplies and DC/DC converters for industrial and telecom equipment.

For engineers reviewing the SBR10U150CTFP datasheet, SBR10U150CTFP pinout, SBR10U150CTFP application, or SBR10U150CTFP equivalent, key selection criteria include forward voltage drop at 5–10A, thermal resistance (4°C/W junction-to-case), leakage current at 125°C, isolation voltage rating (2000VAC), and RoHS/Green compliance status.

Technical Context

This dual-leg rectifier integrates two independent super barrier diode elements sharing a common cathode terminal, enabling synchronous half-wave or center-tapped full-wave rectification. Its patented super barrier structure delivers lower VF than Schottky diodes while maintaining higher temperature stability and reduced reverse leakage.

The ITO-220AB package provides electrical isolation between terminals and heatsink (2000VAC, 3s), supporting direct mounting to grounded metal chassis without insulating hardware. Thermal performance is optimized for forced-air or passive heatsink operation up to 175°C junction temperature.

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 systems-targeting AC/DC adapters, server PSUs, and industrial power supplies demanding low VF, soft switching, and robust thermal performance.

FAQ

What is the maximum junction temperature for SBR10U150CTFP?

The absolute maximum junction temperature is +175°C, with continuous operation supported from –65°C to +175°C. Derating begins at +25°C ambient per Figure 4 in DS30954 Rev.9, where IO drops linearly to zero at +125°C ambient for ITO-220AB without heatsink.

Can SBR10U150CTFP be used in place of a standard Schottky diode?

Yes, but only where its 150V VRRM and dual-common-cathode topology match the circuit. Its super barrier construction provides lower VF than most Schottkys at high temperature and superior leakage control, though it lacks the zero-recovery charge of true Schottky devices.

Is heatsink mounting mandatory for SBR10U150CTFP?

Heatsink mounting is required for any continuous operation above ~2A per leg. With RθJC = 4°C/W and Pd = VF × IF, even at 5A and 0.63V, power dissipation exceeds 3W-exceeding the 1.2W natural convection limit of the ITO-220AB package.

Does the "FP" suffix indicate a different die or just packaging?

The "FP" suffix denotes the ITO-220AB package with isolated tab and green molding compound. Electrically and thermally, the die is identical to the TO-220AB SBR10U150CT; only mechanical form factor, isolation rating, and environmental compliance differ.
