Diodes Incorporated SBRT15M50AP5-13

Overview

SBRT15M50AP5 from Diodes Incorporated is a 50V, 15A Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, featuring 0.54V max forward voltage at 15A/25°C, 0.15mA max reverse leakage at 50V/25°C, and 2°C/W typical junction-to-case thermal resistance. It serves as a high-efficiency freewheeling or polarity protection diode in compact AC/DC adapters and DC/DC converters.

For engineers reviewing the SBRT15M50AP5 datasheet, SBRT15M50AP5 pinout, SBRT15M50AP5 application, or SBRT15M50AP5 equivalent, key selection criteria include low-temperature-stable IR (<0.15mA @125°C), ultra-thin 1.1mm profile, and thermally optimized copper-pad mounting for high-power-density designs.

Technical Context

This Trench SBR uses proprietary trench-structured super barrier technology to achieve lower forward voltage and superior high-temperature reverse leakage stability versus conventional Schottky or fast recovery diodes. Its 50V VRRM rating targets secondary-side rectification in ≤12V output power supplies.

The device operates across –55°C to +150°C with RθJC = 2°C/W and RθJL = 4°C/W, enabling high-current conduction while maintaining junction temperature control on FR4 PCBs with 1-inch copper pads and HK1 heatsink support.

FAQ

What is the recommended PCB pad layout for optimal thermal performance?

The SBRT15M50AP5 requires a minimum 1-inch square copper pad connected to the exposed cathode terminal, per Diodes Inc. AP02001 guidelines. Use thermal vias (≥6x 0.3mm diameter) beneath the pad to inner-layer ground planes. Avoid solder mask over the pad to maximize thermal conduction and minimize RθJA.

Can SBRT15M50AP5 replace a standard Schottky diode in an existing 12V/10A flyback design?

Yes - it can directly replace Schottkys with matching VRRM and IO ratings. Its 0.54V VF is comparable, but its 0.15mA IR at 25°C is significantly lower than typical Schottky leakage (0.5–2mA), improving no-load efficiency and thermal margin in sealed adapters.

Is SBRT15M50AP5 suitable for automotive under-hood applications?

It operates from –55°C to +150°C and maintains stable IR up to 125°C, meeting extended temperature requirements for infotainment and body-control modules. However, it is not AEC-Q101 qualified; for certified automotive use, consult Diodes Inc.'s AEC-Q101-qualified SBR variants.

What does the "P5" suffix indicate in SBRT15M50AP5?

The "P5" denotes the POWERDI®5 package variant. This distinguishes it from TO-220AB (CT), TO-252 (DPAK), or TO-263 (D2PAK) versions of the same die. All SBRT15M50A-x parts share identical electrical specs but differ in thermal and mechanical implementation.
