Diodes Incorporated SBR30150CTFP

Overview

SBR30150CTFP from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 150V peak reverse voltage, with typical forward voltage of 0.82V at 15A and 125°C, designed for high-efficiency AC/DC and DC/DC power conversion in industrial SMPS and server power supplies.

For engineers reviewing the SBR30150CTFP datasheet, SBR30150CTFP pinout, SBR30150CTFP application, or SBR30150CTFP equivalent, key selection criteria include its low VF at high temperature, 200A non-repetitive surge rating, 2000V isolation (ITO-220AB), soft switching behavior, and RoHS-compliant green molding compound.

Technical Context

This device integrates two independent 15A rectifying legs sharing a common cathode terminal, enabling full-wave center-tap or dual-output configurations. Its patented Super Barrier structure replaces traditional PN junctions with a metal-semiconductor barrier, delivering lower conduction loss than standard Schottky diodes while maintaining superior thermal stability up to +175°C junction temperature.

The ITO-220AB package provides electrically isolated mounting via 2000V AC isolation between terminals and heatsink, supporting direct bolt-down thermal management. Electrical performance is characterized across -65°C to +175°C, with leakage current limited to 10mA at 150V and +125°C - critical for high-reliability offline power stages.

FAQ

What is the difference between SBR30150CTFP and SBR30150CT?

SBR30150CTFP uses the ITO-220AB package with electrically isolated mounting tab (2000V AC isolation), while SBR30150CT uses standard TO-220AB without isolation. Both share identical electrical specs, but ITO-220AB enables direct heatsink grounding in Class I systems without insulating hardware.

Can SBR30150CTFP replace a standard 30A Schottky diode in a 100kHz flyback converter?

Yes - its soft switching behavior and low Qrr reduce EMI generation versus Schottky diodes, and its 0.82V VF at 125°C maintains efficiency better under thermal stress. However, verify layout parasitics, as its dual-anode configuration requires symmetric trace routing to avoid current imbalance.

Is the "Green" designation verified per JEDEC J-STD-609?

Yes - Diodes Incorporated certifies SBR30150CTFP as halogen-free (<900ppm Br + Cl, <1000ppm Sb) per their internal specification aligned with JEDEC J-STD-609A, and confirms RoHS 2 compliance (2011/65/EU) with all applicable exemptions applied.

What thermal derating applies above 25°C ambient?

Per Figure 4, average forward current drops linearly from 15A/leg at 25°C to 0A at 150°C ambient. At 85°C ambient, max continuous current is ~9.5A/leg (19A total). Derating assumes proper heatsinking per Note 7 (37mm × 50mm × 15mm black aluminum).
