Taiwan Semiconductor Corporation MBRS25100CT

Overview

MBRS25100CT from Taiwan Semiconductor is a 25A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 100V repetitive peak reverse voltage (V_RRM), 200A surge current (I_FSM), and maximum junction temperature of 150°C. It delivers low forward voltage (0.92V at 25A/25°C) and ultra-low reverse leakage (100µA at 100V/25°C), enabling high-efficiency power conversion in compact DC/DC and SMPS designs.

For engineers reviewing the MBRS25100CT datasheet, MBRS25100CT pinout, MBRS25100CT application, or MBRS25100CT equivalent, key selection criteria include its dual-common-cathode configuration, 1°C/W junction-to-case thermal resistance, guard-ring overvoltage protection, RoHS/halogen-free compliance, and suitability for automated SMT placement in high-density power stages.

Technical Context

This dual-die Schottky rectifier integrates two independent anodes sharing a common cathode terminal, supporting synchronous rectification or dual-output configurations. Its low V_F and fast recovery (no reverse recovery charge) minimize conduction and switching losses in high-frequency converters.

The TO-263AB package provides robust thermal performance (R_θJC = 1°C/W) and mechanical reliability with matte tin-plated leads compliant to J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked on the device body per standard orientation.

FAQ

What is the maximum junction temperature rating for MBRS25100CT?

The MBRS25100CT has a maximum junction temperature (T_J) rating of +150°C, allowing reliable operation in high-ambient industrial environments. This rating is supported by its 1°C/W junction-to-case thermal resistance and TO-263AB package construction. Derating curves in the datasheet specify allowable forward current reduction above 25°C ambient, ensuring safe operation up to the absolute limit. Thermal design must account for PCB copper area and heatsinking to maintain MBRS25100CT junction temperature within this bound.

Does MBRS25100CT support automated SMT placement?

Yes, MBRS25100CT is qualified for automated surface-mount placement per J-STD-020 moisture sensitivity level 1, meaning it can be used directly from dry pack without baking. Its TO-263AB (D2PAK) package features matte tin-plated leads compliant with J-STD-002 solderability standards, and the device is supplied in 800-unit tape-and-reel format optimized for pick-and-place machines. No special handling or pre-conditioning is required prior to reflow soldering.

What is the forward voltage of MBRS25100CT at full rated current?

The MBRS25100CT exhibits a maximum forward voltage (V_F) of 0.92 V at 25 A and 25°C junction temperature. At elevated temperature (125°C), V_F drops to 0.88 V under the same current, reflecting the negative temperature coefficient typical of Schottky diodes. These values are measured per diode in the dual-die configuration and are critical for calculating conduction losses in high-current power stages using MBRS25100CT.

How does the guard ring feature benefit MBRS25100CT in real-world use?

The guard ring structure in MBRS25100CT improves edge termination robustness, preventing premature avalanche breakdown at the die periphery during voltage transients or non-uniform electric field conditions. In practice, this increases the device's immunity to line surges and ringing in switching power supplies, extending lifetime in applications like telecom rectifiers and industrial SMPS where repetitive overvoltage stress occurs. It also enhances parameter consistency across manufacturing lots.

Is MBRS25100CT halogen-free and RoHS compliant?

Yes, MBRS25100CT is both halogen-free per IEC 61249-2-21 and RoHS compliant, meeting EU Directive 2011/65/EU requirements. The molding compound contains no brominated or chlorinated flame retardants, and all homogeneous materials pass RoHS substance restrictions. This compliance supports environmental certification for end equipment including servers, industrial controllers, and telecom infrastructure where regulatory documentation is mandatory for market access.
