Taiwan Semiconductor Corporation MBR20200PT

Overview

MBR20200PT from Taiwan Semiconductor is a 20A, 200V dual-die Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 1.02V max forward voltage at 20A/25°C and 0.98V at 20A/125°C, with 150A surge current rating and 1°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in high-power SMPS and DC-DC converters requiring low conduction loss and robust thermal performance.

For engineers reviewing the MBR20200PT datasheet, MBR20200PT pinout, MBR20200PT application, or MBR20200PT equivalent, key selection criteria include its 200V repetitive peak reverse voltage, dual-die configuration enabling parallel internal paths, AEC-Q101 qualification option (H-suffix), UL recognition, and compatibility with high-temperature operation up to 150°C junction temperature.

Technical Context

The MBR20200PT implements a dual-die Schottky structure housed in a single TO-247AD case, delivering 20A average forward current with 150A non-repetitive surge capability. Its 200V V_RRM rating supports high-input-voltage industrial and telecom power supplies.

Thermal design is enabled by a low 1°C/W R_θJC, while guard ring protection ensures stable operation under transient overvoltage conditions. Reverse leakage remains ≤5mA at 125°C and rated VR, supporting reliable performance in thermally demanding environments.

FAQ

What is the maximum junction temperature rating for the MBR20200PT?

The MBR20200PT has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings in the official datasheet. This allows operation in high-ambient environments such as enclosed power supplies or industrial enclosures. Derating curves confirm 20A continuous current is sustainable up to 100°C case temperature when properly heatsinked. The MBR20200PT must be mounted with ≤1.13 N·m torque to maintain thermal integrity without damaging the TO-247AD package.

Does the MBR20200PT have AEC-Q101 qualification?

The base MBR20200PT is not AEC-Q101 qualified; however, the MBR20200PTH variant-with 'H' suffix-is explicitly qualified per AEC-Q101 Rev D. Both share identical electrical and thermal specifications, including 200V V_RRM, 20A I_F, and 1.02V V_F max. The MBR20200PTH undergoes additional stress testing for automotive-grade reliability, making it suitable for infotainment and body control module power supplies where qualification is mandatory.

What is the forward voltage of the MBR20200PT at full load and elevated temperature?

At 20A and 25°C, the MBR20200PT exhibits a maximum forward voltage (V_F) of 1.02V. At the same 20A current but elevated junction temperature of 125°C, V_F drops to 0.98V max due to Schottky diode physics. This lower V_F at high temperature improves thermal stability in continuous operation. The MBR20200PT's dual-die structure further mitigates localized heating, helping sustain this performance across the full 150°C junction limit.

How does the dual-die configuration of the MBR20200PT improve performance compared to single-die equivalents?

The MBR20200PT integrates two independent Schottky dies in one TO-247AD package, enabling current sharing that reduces effective forward voltage and thermal hotspot formation. This yields measurable improvements: lower total conduction loss, more uniform thermal distribution across the die area, and enhanced surge resilience due to parallel current paths. Unlike single-die devices such as MBR20200CT, the MBR20200PT avoids current crowding and provides inherent redundancy-key for mission-critical 20A power rails.

What packaging and marking information applies to the MBR20200PT?

The MBR20200PT is supplied in TO-247AD (TO-3P) package with matte tin-plated leads compliant with J-STD-002 solderability standards. Marking includes "MBR20200PT" as the full part number, green compound indicator (G), factory code (F), and date code (YWW). Devices are packed 30 per tube. Polarity is marked on the body, and the metal tab is electrically isolated-critical for safe mounting to heatsinks without additional insulation when referenced to circuit ground.
