Taiwan Semiconductor Corporation MBRF30200CT-Y

Overview

MBRF30200CT-Y from Taiwan Semiconductor is a 30A, 200V dual-die Schottky barrier rectifier in ITO-220AB package, featuring 1.05V max forward voltage at 30A/25°C and 0.92V at 30A/125°C, with 200A surge capability and 4°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in high-frequency SMPS and DC-DC converters.

For engineers reviewing the MBRF30200CT-Y datasheet, MBRF30200CT-Y pinout, MBRF30200CT-Y application, or MBRF30200CT-Y equivalent, key selection criteria include rated reverse voltage (200V), continuous forward current (30A), thermal performance (R_θJC = 4°C/W), and dual-common-cathode configuration for center-tapped transformer designs.

Technical Context

This device integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its low forward voltage drop and fast switching enable high efficiency in 20–200 kHz power conversion topologies.

The 200V V_RRM, 200A I_FSM, and 10,000 V/µs dv/dt rating support robust operation under transient overvoltage and high di/dt conditions typical in flyback and forward converter secondary-side rectification.

FAQ

What is the maximum junction temperature rating for MBRF30200CT-Y?

The MBRF30200CT-Y has a maximum junction temperature (T_J) of 150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation in sealed industrial enclosures with ambient temperatures up to 85°C when mounted on an appropriately sized heatsink. Derating curves confirm usable current capacity down to 15A at 125°C case temperature. The MBRF30200CT-Y must be operated within this thermal limit to ensure long-term reliability and prevent parametric shift.

Does MBRF30200CT-Y have a guard ring, and why does it matter?

Yes, the MBRF30200CT-Y incorporates a guard ring structure explicitly documented in its features list and confirmed in the "Features" section of the Taiwan Semiconductor datasheet. This guard ring prevents premature edge breakdown under high electric field stress, especially critical at its 200V V_RRM rating. In practice, it improves surge immunity and long-term stability in applications exposed to fast dv/dt transients, such as switch-mode power supplies with high-frequency transformers. The MBRF30200CT-Y's guard ring directly contributes to its 10,000 V/µs rated dv/dt capability.

What is the forward voltage of MBRF30200CT-Y at full load and elevated temperature?

The MBRF30200CT-Y exhibits a maximum forward voltage (V_F) of 0.92V at 30A and 125°C junction temperature, per the Electrical Specifications table in the official datasheet. At room temperature (25°C) and 30A, V_F is 1.05V max. This temperature-dependent reduction reflects the negative temperature coefficient of Schottky diodes and ensures predictable conduction loss behavior across the full industrial operating range. Designers use these values to calculate worst-case power dissipation (P_cond = I_F × V_F) for thermal analysis of the MBRF30200CT-Y.

Is MBRF30200CT-Y halogen-free and RoHS compliant?

Yes, the MBRF30200CT-Y is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the "Features" section of the official Taiwan Semiconductor documentation. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards. These compliance attributes make the MBRF30200CT-Y suitable for export to EU, Japan, and other regulated markets where halogen content restrictions apply. No exemptions or exceptions are noted for the MBRF30200CT-Y in the published specifications.

What package type and mounting torque does MBRF30200CT-Y use?

The MBRF30200CT-Y uses the ITO-220AB package - a thermally enhanced variant of TO-220 with isolated metal tab and optimized internal leadframe geometry. Mechanical data specify a maximum mounting torque of 0.56 N·m for the screw terminal, and the device meets JESD 201 Class 1A whisker testing. Polarity is marked on the case, and weight is approximately 1.70g. This package enables direct heatsink attachment while maintaining electrical isolation between the cathode tab and heatsink mounting surface, a key requirement in many MBRF30200CT-Y implementations.
