Diodes Incorporated SBRT10M50SP5-13

Overview

SBRT10M50SP5 from Diodes Incorporated is a 10A, 50V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, delivering VF = 0.47 V at 10A/25°C and IR = 0.15 mA at 50V/125°C. It serves as a high-efficiency freewheeling or polarity protection diode in compact AC/DC adapters and DC/DC converters.

For engineers reviewing the SBRT10M50SP5 datasheet, SBRT10M50SP5 pinout, SBRT10M50SP5 application, or SBRT10M50SP5 equivalent, key selection criteria include ultra-low forward voltage at elevated temperature, thermally robust junction-to-lead resistance (RθJL = 4 °C/W), AEC-Q101 qualification, and <1.1 mm profile for space-constrained power stages.

Technical Context

This SBR uses trench-based super barrier technology to achieve lower VF and superior IR stability versus conventional Schottky diodes. Its design targets high-frequency switching power supplies where conduction loss and thermal runaway risk must be minimized across -55°C to +150°C ambient operation.

The POWERDI®5 package integrates a bottom-side heat sink with low RθJC (2 °C/W) and RθJL (4 °C/W), enabling direct PCB copper pad thermal coupling. Pin configuration supports cathode-anode connection with mandatory PCB-level electrical tie between left and right terminals.

FAQ

What is the thermal resistance from junction to PCB copper via the POWERDI®5 bottom pad?

The typical thermal resistance from junction to case (RθJC) is 2 °C/W when mounted on an FR4 PCB with a 1-inch copper pad and AL substrate per datasheet Note 5. This value assumes optimal thermal pad layout per AP02001 guidelines and enables effective heat transfer to the PCB plane.

Does SBRT10M50SP5 support bidirectional current flow?

No. SBRT10M50SP5 is a unidirectional rectifier diode with anode and cathode terminals. It conducts only from anode to cathode under forward bias and blocks current in reverse bias up to 50 V. Bidirectional operation would require external circuitry or a different device type.

Can SBRT10M50SP5 replace a standard Schottky diode in existing layouts?

Yes, provided the PCB pad layout matches the POWERDI®5 outline (AP02002) and the left/right pin tie is implemented. Its 0.47 V VF at 10A/25°C and superior IR stability at high temperature often allow direct substitution with improved thermal margin and reduced conduction loss.

Is the marking "T10M50S" sufficient to identify this part on the board?

Yes. "T10M50S" is the official product type marking code per the datasheet, indicating SBRT10M50SP5. Combined with the POWERDI®5 package and date code (YYWWK), it provides full traceability and distinguishes it from other SBR variants in Diodes' portfolio.
