Taiwan Semiconductor Corporation MBRF10200

Overview

MBRF10200 from Taiwan Semiconductor is a 10A, 200V Schottky barrier rectifier in ITO-220AC package, featuring 1.05V forward voltage at 10A/25°C, 2mA reverse leakage at 200V/125°C, and 150A surge current capability-designed for high-efficiency DC-DC converters in automotive power systems.

For engineers reviewing the MBRF10200 datasheet, MBRF10200 pinout, MBRF10200 application, or MBRF10200 equivalent, key selection criteria include VRRM=200V, IF=10A continuous, TJ(max)=150°C, RθJC=4°C/W, and AEC-Q101 qualification availability (H-suffix variant).

Technical Context

The MBRF10200 uses a single-die Schottky junction optimized for low forward voltage and fast switching in high-frequency SMPS topologies. Its guard ring structure provides over-voltage protection, and its ITO-220AC package enables direct heatsink mounting with 0.56 N·m max torque.

Rated for 200V repetitive peak reverse voltage and 140V RMS reverse voltage, it delivers 20A peak repetitive forward current under square-wave 20kHz conditions while maintaining <2mA reverse leakage at 125°C-critical for thermal-stable industrial power rails.

FAQ

What is the maximum junction temperature rating for MBRF10200?

The MBRF10200 has a maximum junction temperature (TJ(max)) of +150°C. This rating defines the upper thermal limit for reliable operation and is used in derating calculations for continuous forward current. At case temperatures above 100°C, the device must be derated per the forward current derating curve in the datasheet. Thermal design must ensure that actual junction temperature under worst-case load and ambient conditions remains below this threshold to prevent parametric shift or premature failure. The MBRF10200's RθJC of 4°C/W supports this requirement when properly mounted to an adequate heatsink.

Is MBRF10200 AEC-Q101 qualified?

The base MBRF10200 is not AEC-Q101 qualified; however, the MBRF10200H variant is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening including stress tests for temperature cycling, highly accelerated life testing (HALT), and electrostatic discharge. For automotive applications requiring qualification evidence, MBRF10200H must be specified. The base part shares identical electrical and thermal specifications but lacks the documented test reports required for automotive Tier-1 acceptance.

What is the forward voltage drop of MBRF10200 at 10A and 125°C?

The MBRF10200 datasheet does not specify a maximum forward voltage (VF) at 10A and 125°C; only the 25°C condition (VF ≤ 1.05V) is guaranteed. However, typical VF decreases with rising junction temperature for Schottky diodes-data shows ~0.71V for MBRF10100 at 125°C, implying MBRF10200 likely operates near 0.85–0.95V under those conditions. Designers should use the 25°C max value for worst-case loss calculation unless thermal simulation confirms lower junction temperature.

Can MBRF10200 replace MBRF10100 in a design?

Yes, MBRF10200 can replace MBRF10100 in most cases because it meets or exceeds all key parameters: same IF=10A, higher VRRM=200V vs. 100V, improved IFSM=150A, and compatible ITO-220AC package. However, VF is higher (1.05V vs. 0.85V), increasing conduction loss by ~25% at full load. Thermal design must verify junction temperature remains within limits. No PCB changes are needed, but efficiency and thermal margin should be revalidated, especially in high-ambient or sealed environments.

What is the reverse leakage current of MBRF10200 at rated voltage and elevated temperature?

At rated reverse voltage (200V) and junction temperature of 125°C, the MBRF10200 exhibits a maximum reverse leakage current (IR) of 2 mA. This value is confirmed in the Electrical Specifications table and is significantly lower than lower-voltage variants in the family (e.g., 6 mA for MBRF1090). Low IR at high temperature is critical for minimizing standby power loss in always-on automotive modules and improves reliability in thermally stressed industrial power supplies.
