Diodes Incorporated SBR30300CTFP

Overview

SBR30300CTFP from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier rated for 300V peak reverse voltage, with typical forward voltage of 0.76V at 15A and 25°C, soft-switching reverse recovery time of 25ns, and ITO-220AB package optimized for high-efficiency AC/DC front-end rectification in industrial power supplies.

For engineers reviewing the SBR30300CTFP datasheet, SBR30300CTFP pinout, SBR30300CTFP application, or SBR30300CTFP equivalent, key selection criteria include its low VF at high temperature (0.92V @ 15A, 125°C), 200A non-repetitive surge rating, 2000V isolation between terminals and heatsink, and RoHS-compliant matte tin finish on copper leadframe.

Technical Context

This dual-diode rectifier integrates two independent 300V/15A legs in a single ITO-220AB thermally enhanced package, sharing a common cathode terminal. Its patented Super Barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to reduce forward conduction loss while maintaining fast, soft recovery behavior.

Designed for high-frequency switching converters, it delivers stable leakage current (<0.1mA @ 300V, 25°C) and minimal thermal resistance (RθJC = 4°C/W), enabling operation up to +175°C junction temperature without derating in forced-air or heatsink-mounted configurations.

FAQ

What is the maximum operating temperature for SBR30300CTFP?

The SBR30300CTFP has an operating junction temperature range of –65°C to +175°C. Its ITO-220AB package achieves RθJC = 4°C/W, enabling full 15A per leg current at 100°C case temperature when properly heatsinked. Derating begins above 125°C case per Figure 1 in DS30995 Rev. 6–2.

How does SBR30300CTFP differ from standard Schottky rectifiers?

Unlike conventional Schottky diodes, SBR30300CTFP uses a patented super barrier structure that combines metal-semiconductor and PN-junction characteristics-delivering Schottky-like low VF (0.76V) with PN-like high VR (300V) and soft recovery (25ns trr), avoiding the trade-off between voltage rating and switching speed.

Can SBR30300CTFP be used in place of a single TO-220 full-bridge rectifier?

No-SBR30300CTFP is a dual common-cathode rectifier (two anodes, one cathode), not a full-bridge. It replaces half of a bridge (e.g., two series diodes in a center-tapped configuration) or serves as a dual-output rectifier. A full bridge requires four discrete diodes or a dedicated bridge package like GBU3030.

Is the ITO-220AB tab electrically isolated from all pins?

Yes-the ITO-220AB package provides 2000V AC isolation between the metal tab (heatsink interface) and all three terminals (pins 1, 2, 3). This eliminates the need for mica washers or silicone pads in high-voltage designs, simplifying mechanical assembly and improving thermal contact reliability.
