Taiwan Semiconductor Corporation MBRS25150CT MNG

Overview

MBRS25150CT from Taiwan Semiconductor is a 25A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 150V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C; it delivers low forward voltage drop (1.02V at 25A/25°C) and is optimized for high-efficiency DC-DC converters.

For engineers reviewing the MBRS25150CT datasheet, MBRS25150CT pinout, MBRS25150CT application, or MBRS25150CT equivalent, key selection criteria include VRRM rating, thermal resistance (RθJC = 1°C/W), forward voltage at operating current and temperature, reverse leakage at 150V and 125°C (5mA max), and TO-263AB mechanical compatibility with automated SMT placement.

Technical Context

This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-263AB surface-mount package, enabling full-wave rectification or parallel current handling without external paralleling. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.

The device operates across -55°C to +150°C junction temperature range, exhibits dv/dt capability of 10,000 V/μs, and maintains stable reverse leakage (≤5 mA at VR = 150 V, TJ = 125°C), making it suitable for high-frequency switching topologies where fast recovery and low conduction loss are critical.

FAQ

What is the maximum junction temperature rating for MBRS25150CT?

The MBRS25150CT has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating defines the upper thermal limit for reliable operation; sustained operation above this temperature risks permanent degradation. Derating curves show usable current drops as case temperature rises, and thermal design must maintain TJ ≤ 150°C under worst-case load and ambient conditions. The MBRS25150CT's RθJC of 1°C/W directly informs heatsinking requirements.

Does MBRS25150CT support automated SMT assembly?

Yes, MBRS25150CT is explicitly designed for automated placement per its mechanical data: TO-263AB (D2PAK) package, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 (J-STD-020), meaning no pre-bake is required before reflow. Its 1.37g weight and standardized footprint enable high-yield pick-and-place integration. The MBRS25150CT's polarity marking and pad layout recommendations further support consistent orientation and solder joint reliability in volume manufacturing.

What is the reverse leakage current specification for MBRS25150CT at 150V and 125°C?

The MBRS25150CT specifies a maximum reverse leakage current (IR) of 5 mA at rated VRRM = 150 V and junction temperature TJ = 125°C, per electrical specifications table. This value is measured under pulse test conditions (PW = 30 ms) and reflects worst-case leakage under elevated thermal and voltage stress. Lower leakage at room temperature (≤100 µA) confirms strong blocking behavior; the 5 mA figure is critical for calculating standby power loss in high-temperature applications like enclosed adapters or industrial converters using MBRS25150CT.

Is MBRS25150CT RoHS and halogen-free compliant?

Yes, MBRS25150CT is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as confirmed in the FEATURES section of the official datasheet. The molding compound meets UL 94V-0 flammability rating, and all plating and materials are qualified to current environmental directives. This compliance ensures suitability for export to EU, China, and other regulated markets, and supports green manufacturing initiatives for products incorporating MBRS25150CT.

How does the guard ring feature benefit MBRS25150CT in real-world applications?

The guard ring in MBRS25150CT enhances edge termination robustness, improving resistance to localized electric field crowding during voltage transients. This directly increases avalanche ruggedness and reduces risk of premature breakdown under surge or line-spike conditions-especially valuable in unregulated inputs or flyback converters. Unlike basic Schottky diodes, MBRS25150CT's guard ring allows it to withstand overvoltage events without external TVS clamping in many SMPS and adapter designs, simplifying circuit protection and improving long-term reliability of the MBRS25150CT in field-deployed equipment.
