Diodes Incorporated SBR30100CTFP

Overview

SBR30100CTFP from Diodes Incorporated is a 100 V, 30 A dual common-cathode Super Barrier Rectifier in ITO-220AB package, featuring 0.75 V forward voltage at 15 A and 125°C, 200 A non-repetitive surge rating, and 2000 V isolation between terminals and heatsink-designed for high-efficiency AC/DC front-end rectification in industrial power supplies.

For engineers reviewing the SBR30100CTFP datasheet, SBR30100CTFP pinout, SBR30100CTFP application, or SBR30100CTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), high-temperature leakage stability (10 mA max at 125°C), soft switching behavior, and RoHS-compliant green molding compound compatibility with automated reflow and wave soldering.

Technical Context

This dual-diode rectifier integrates two independent 100 V, 15 A per-leg Super Barrier structures sharing a common cathode terminal, enabling full-wave center-tap or parallel-output configurations. Its patented barrier technology replaces traditional PN junctions with low-barrier metal-semiconductor interfaces to reduce forward conduction loss while maintaining high reverse blocking integrity.

The ITO-220AB package provides electrically isolated mounting via 2000 VAC terminal-to-heatsink isolation, supporting direct bolt-down thermal management without insulating washers. Thermal derating follows a linear curve from 30 A at 25°C ambient to zero at 125°C, validated under 60 Hz resistive load conditions with heatsink (45 mm × 20 mm × 12 mm black aluminum).

Key Specifications

Pinout & Package

Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab, matte tin-plated copper leadframe, UL 94V-0 molded plastic body (1.65 g), and footprint compatible with standard TO-220 heatsinks.

Equivalent & Alternatives

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

Compared with STPS30H100CG and MBR30100CT, SBR30100CTFP trades slightly higher room-temperature VF for superior high-temperature stability, integrated isolation, and environmental compliance-making it optimal for thermally constrained, safety-certified, and sustainability-driven power systems.

FAQ

What is the difference between SBR30100CTFP and SBR30100CT?

The SBR30100CTFP uses the ITO-220AB package with electrically isolated tab (2000 VAC terminal-to-heatsink), while SBR30100CT uses standard TO-220AB without isolation. Both share identical electrical specs, but ITO-220AB eliminates need for insulating hardware in grounded-chassis designs and offers slightly higher RθJC (4°C/W vs. 2°C/W).

Can SBR30100CTFP replace a standard 30A Schottky rectifier in existing designs?

Yes, provided the PCB footprint matches ITO-220AB dimensions and thermal/mechanical mounting accounts for the isolated tab. Electrical replacement is direct, but verify that 0.75 V VF at 125°C meets your system's conduction loss target-especially in high-ambient environments where Schottky VF rises more steeply.

Is heatsinking required for continuous 30 A operation?

Yes. At 30 A total current and 25°C ambient, junction temperature reaches ~125°C using the specified 45 mm × 20 mm × 12 mm heatsink. For sustained operation above 25°C ambient, active cooling or larger heatsinks are required-derating follows Fig. 4, reaching zero current at 125°C ambient.

Does SBR30100CTFP support reflow soldering?

Yes. The matte tin finish on the copper leadframe is qualified to MIL-STD-202 Method 208 and compatible with standard lead-free reflow profiles (peak 260°C, 60 sec max). Ensure board layout provides adequate thermal relief on pins to avoid tombstoning during reflow.
