Diodes Incorporated SBR20100CTFP

Overview

SBR20100CTFP from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier with 100V peak repetitive reverse voltage, 0.82V max forward voltage at 10A/25°C, 0.1mA max reverse leakage at 100V/25°C, and ITO-220AB package. It serves as a high-efficiency, thermally stable rectifier or freewheel diode in DC-DC converters and AC-DC adapters.

For engineers reviewing the SBR20100CTFP datasheet, SBR20100CTFP pinout, SBR20100CTFP application, or SBR20100CTFP equivalent, key selection criteria include its ultra-low VF, high-temperature IR stability, avalanche ruggedness, TO-220 variant package isolation, and dual-leg current rating for synchronous rectification topologies.

Technical Context

This device implements patented SBR® technology-distinct from Schottky and standard PN junctions-to deliver superior avalanche energy handling (10 mJ) and reduced thermal runaway risk. Its dual common-cathode configuration enables independent leg operation with shared thermal path and symmetrical electrical characteristics per leg.

Rated for 100V VRRM and 10A average current per leg (20A total), it operates across –65°C to +175°C with 4°C/W typical junction-to-case thermal resistance in ITO-220AB. Reverse leakage remains ≤10mA at 125°C, enabling reliable performance in high-ambient industrial power supplies.

FAQ

What is the maximum junction temperature and how is it validated?

The SBR20100CTFP has a rated operating junction temperature range of –65°C to +175°C, verified per JEDEC JESD22-A108F. Thermal characterization was performed using transient dual-interface testing with calibrated thermocouples on die surface under 10A DC bias, confirming 175°C absolute maximum with 4°C/W RθJC in ITO-220AB.

Does the ITO-220AB package require thermal interface material when mounted to a heatsink?

No-ITO-220AB integrates a molded dielectric barrier between the metal tab and internal die, enabling direct mechanical mounting to grounded heatsinks without thermal pads or insulators. The 2000V RMS isolation rating is maintained under 25N clamping force per Diodes' package specification DS30956 Rev. 16-2.

How does SBR® technology differ from standard Schottky and fast recovery diodes?

SBR® uses a modified epitaxial structure with controlled doping gradients to achieve Schottky-like VF while suppressing minority-carrier injection-eliminating reverse recovery charge (Qrr ≈ 0) and enabling true avalanche-rated operation. Unlike Schottkys, it avoids catastrophic failure under repetitive surge, and unlike FRDs, it exhibits no reverse recovery loss.

Can SBR20100CTFP replace MBR20100CT in existing designs without layout changes?

Yes-SBR20100CTFP shares identical pinout, footprint, and mechanical dimensions with MBR20100CT in TO-220AB form, but ITO-220AB variant requires verification of heatsink clearance due to insulated tab height. Electrical substitution improves thermal stability and surge immunity without altering PCB layout or bill of materials.
