Product details
Overview
SBR20100CTP from Diodes Incorporated is a 20A dual common-cathode super barrier rectifier in ITO-220S package, rated for 100V peak reverse voltage, with typical forward voltage of 0.75V at 10A/125°C and thermal resistance of 3°C/W junction-to-case. It delivers soft fast switching and low conduction loss in high-efficiency DC/DC converters and automotive power supplies.
For engineers reviewing the SBR20100CTP datasheet, SBR20100CTP pinout, SBR20100CTP application, or SBR20100CTP equivalent, key selection criteria include its isolated heatsink tab, AEC-Q101 qualification, 4000V isolation rating, and derated current capability across -65°C to +175°C operating range.
Technical Context
This dual-leg super barrier rectifier integrates two Schottky barrier chips sharing a common cathode terminal, enabling synchronous half-bridge or dual-output configurations. Its ITO-220S package features an electrically isolated heatsink tab rated for 4000V AC isolation, supporting direct mounting to grounded chassis without insulation pads.
The device operates with soft recovery characteristics to minimize EMI in switching power supplies, and exhibits leakage current ≤10μA at 100V/125°C - critical for high-temperature automotive under-hood applications where thermal stability is mandatory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBR20100CT | Same die and electrical specs; uses standard ITO-220AB package with non-isolated tab. | Requires insulating pad and shoulder washer for heatsink mounting; unsuitable where tab grounding is mandatory. | Select when cost sensitivity outweighs isolation requirement and thermal interface design permits insulation. |
| SBR20U100CT | Ultra-low VF variant (0.68V typ @ 10A/125°C); higher IR (25μA @ 100V/125°C). | Better efficiency in low-voltage, high-current apps; reduced leakage margin for high-temp standby modes. | Prefer for battery-powered or energy-star-compliant systems where conduction loss dominates over leakage. |
Compared with SBR20100CTP, SBR20100CT lacks electrical isolation on the tab - requiring additional hardware for grounded mounting - while SBR20U100CT trades higher leakage for lower VF, making it optimal only when thermal headroom exists and standby current is not critical.

FAQ
Is SBR20100CTP still in production?
No - Diodes Incorporated officially discontinued SBR20100CTP as of October 2015. However, Aetrix Electronics maintains legacy inventory with full traceability and provides lifecycle coordination support for ongoing production programs requiring this specific ITO-220S isolated-tab variant.
What is the purpose of the isolated heatsink tab?
The Pin 4 heatsink tab is electrically isolated from the cathode (Pin 2) and rated for 4000VAC withstand. This allows direct mechanical mounting to a grounded metal chassis without insulation hardware, reducing thermal resistance and simplifying mechanical design in space-constrained automotive and industrial enclosures.
How does SBR20100CTP differ from standard Schottky rectifiers?
SBR20100CTP uses a proprietary super barrier structure that achieves Schottky-level forward voltage (0.75V @ 10A/125°C) while significantly improving reverse leakage (10μA @ 100V/125°C) and thermal stability beyond conventional Schottky limits - enabling reliable 100V operation at 175°C junction temperature.
Can SBR20100CTP replace a standard 20A TO-220 diode?
Yes, but only if the replacement requires common-cathode dual-leg configuration and isolated heatsink mounting. Its 100V VRRM, 10A/leg rating, and ITO-220S footprint match many TO-220-based designs, though mechanical mounting holes and tab isolation must be verified against the original layout.
