Product details
Overview
MBRS25100CT from Taiwan Semiconductor is a dual-die surface-mount Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 100 V repetitive peak reverse voltage, and 200 A non-repetitive surge current; it delivers low forward voltage (0.92 V at 25 A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in compact DC/DC modules.
For engineers reviewing the MBRS25100CT datasheet, MBRS25100CT pinout, MBRS25100CT application, or MBRS25100CT equivalent, key selection criteria include its dual-common-cathode configuration, 1.0 °C/W junction-to-case thermal resistance, 7.5 mA reverse leakage at 100 V and 125°C, guard-ring overvoltage protection, and RoHS/halogen-free compliance for industrial-grade power supply designs.
Technical Context
The MBRS25100CT integrates two independent Schottky diodes in a single TO-263AB thermally optimized package with common cathode connection, supporting synchronous rectification and dual-output DC/DC topologies. Its 100 V VRRM rating targets mid-voltage SMPS applications where fast switching and low conduction loss are critical.
Designed for high-reliability operation, it features JESD201 Class 2 whisker resistance, moisture sensitivity level 1 per J-STD-020, and UL 94V-0 molding compound. The device sustains 200 A IFSM (8.3 ms half-sine) and exhibits 10,000 V/μs dv/dt capability, ensuring robustness against transient voltage spikes in switching converters.

FAQ
What is the maximum junction temperature rating for MBRS25100CT?
The MBRS25100CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table in the official datasheet Version N2103. This rating allows continuous operation in high-ambient environments such as enclosed power supplies or industrial enclosures without derating until case temperature approaches thermal limits. Thermal design must maintain RθJC = 1.0 °C/W path to ensure MBRS25100CT stays within specification under full 25 A load.
Does MBRS25100CT support automated pick-and-place assembly?
Yes, MBRS25100CT is qualified for automated placement per its mechanical data: matte tin-plated leads meet J-STD-002 solderability requirements, and its TO-263AB (D2PAK) package is compatible with standard SMT feeders and vision alignment systems. The device carries moisture sensitivity level 1 per J-STD-020, eliminating bake requirements prior to reflow-reducing process steps and cost in high-volume manufacturing of MBRS25100CT-based assemblies.
What is the reverse leakage current of MBRS25100CT at 100 V and 125°C?
Per the Electrical Specifications table in datasheet Version N2103, MBRS25100CT exhibits a maximum reverse leakage current (IR) of 7.5 mA at rated VR = 100 V and junction temperature TJ = 125°C. This value is confirmed under 30 ms pulse test conditions and reflects worst-case behavior in high-temperature operation-critical for estimating standby power loss in MBRS25100CT-equipped offline converters.
Is MBRS25100CT halogen-free and RoHS compliant?
Yes, MBRS25100CT complies with both RoHS Directive 2011/65/EU and IEC 61249-2-21 for halogen-free materials. The datasheet explicitly states "Halogen-free according to IEC 61249-2-21" and "RoHS Compliant" in the FEATURES section (Page 1, Version N2103). These certifications apply to the entire device-including molding compound, leadframe, and plating-ensuring MBRS25100CT meets environmental compliance requirements for global electronics markets.
What is the forward voltage drop of MBRS25100CT at 25 A and 25°C?
The forward voltage drop (VF) of MBRS25100CT is specified as a maximum of 0.92 V at IF = 25 A and TJ = 25°C, per the ELECTRICAL SPECIFICATIONS table (Page 3, Version N2103). This value is measured per diode under pulsed conditions and represents the upper bound for conduction loss calculation in MBRS25100CT-based power stages operating near room temperature.
