Product details

Overview

MBRF5200H from Taiwan Semiconductor is an AEC-Q101-qualified 5A, 200V Schottky barrier rectifier in ITO-220AC package, featuring 120A surge current capability, 0.92V max forward voltage at 5A/125°C, and guard ring over-voltage protection-used in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBRF5200H datasheet, MBRF5200H pinout, MBRF5200H application, or MBRF5200H equivalent, key selection factors include its 200V repetitive peak reverse voltage, 150°C maximum junction temperature, UL Recognized status (E-326243), RoHS/halogen-free compliance, and AEC-Q101 qualification for under-hood power conversion.

Technical Context

This single-die Schottky rectifier uses a planar junction structure with integrated guard ring to sustain 200V V_RRM while maintaining low conduction loss. Its 3°C/W junction-to-case thermal resistance enables high-power operation without forced cooling in compact ITO-220AC mounts.

Designed for high-frequency switching applications, it delivers 10A peak repetitive forward current (square wave, 20kHz) and withstands 10,000 V/µs critical dv/dt-critical for noise-immune operation in fast-switching automotive DC-DC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24V/48V automotive systems.
I_F	5 A continuous - Rated average forward current at case temperature ≤75°C; supports sustained output in 60W+ adapters.
I_FSM	120 A - Non-repetitive surge rating (8.3ms half-sine); handles cold-start inrush in SMPS without failure.
V_F max	0.92 V @ 5A, 125°C - Low conduction loss reduces thermal stress and improves efficiency >92% in 12V→5V buck converters.
R_θJC	3 °C/W - Enables direct heatsink mounting; allows 5A operation at T_C = 100°C with <150°C junction limit.
T_J max	150 °C - Extended thermal rating supports under-hood deployment in engine control modules and ADAS power supplies.

Pinout & Package

Package: ITO-220AC - Insulated TO-220 variant with electrically isolated tab (rated 2500V RMS), matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m max mounting torque.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input current entry point	Connected to high-side switch node; must handle full load + surge current without voltage drop-induced timing skew.
Cathode (Lead 2)	Output current exit point	Low-impedance path to output capacitor; low V_F minimizes ripple and thermal rise in regulated rails.
Tab (Isolated)	Thermal interface only	Electrically isolated metal surface for heatsinking; no electrical connection required-enables floating ground designs.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive power electronics per stress test requirements including HTOL, TC, and UHAST-enables use in ASIL-B systems.
Guard ring over-voltage protection	Prevents premature avalanche breakdown at edge regions, ensuring stable 200V blocking across temperature and lifetime.
UL Recognition (E-326243)	Confirms flammability (UL 94V-0), creepage/clearance, and long-term reliability for safety-critical AC-DC front-ends.
125°C-rated V_F	0.92V max ensures predictable conduction loss in hot environments-critical for thermal design margin in sealed enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-50WQ03FN-M3/45	30V V_RRM, 5A, TO-220AC package; lower V_F (0.42V typ), but not AEC-Q101 qualified.	Restricted to non-automotive 3.3–5V rail generation; unsuitable for 200V blocking or under-hood thermal environments.	Select only for cost-sensitive consumer adapters where 200V rating and automotive qualification are unnecessary.
ON Semiconductor MBR5200G	200V V_RRM, 5A, TO-220AC; AEC-Q101 qualified, but R_θJC = 4.5°C/W and V_F = 0.95V max @ 125°C.	Acceptable for automotive use but requires larger heatsink area or derating to 4.2A at 100°C case temp.	Choose when footprint compatibility with legacy ON designs is mandatory, accepting 10% higher thermal resistance.

Compared with VS-50WQ03FN-M3/45 and MBR5200G, the MBRF5200H uniquely combines 200V rating, AEC-Q101 qualification, 3°C/W thermal resistance, and 0.92V V_F-making it optimal for space-constrained, thermally demanding automotive and industrial DC-DC rectification where reliability and efficiency are co-prioritized.

FAQ

What is the maximum junction temperature rating for the MBRF5200H?

The MBRF5200H has a maximum junction temperature (T_J) of 150°C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments where case temperatures reach 100–125°C, provided thermal design maintains R_θJC ≤3°C/W and heatsink interface resistance is controlled. The MBRF5200H's 150°C T_J exceeds standard commercial Schottky diodes rated at 125°C.

Does the MBRF5200H have UL recognition, and what does that cover?

Yes, the MBRF5200H is UL Recognized under File #E-326243. This certification covers flammability (UL 94V-0), dielectric strength (2500V RMS isolation between tab and leads), and long-term reliability of the molding compound and lead finish. It validates suitability for safety-critical AC-DC and DC-DC power supplies in industrial and medical equipment where regulatory compliance is mandatory.

How does the guard ring feature improve reliability in the MBRF5200H?

The guard ring in the MBRF5200H prevents edge-initiated avalanche breakdown under high dv/dt or transient overvoltage conditions. By controlling electric field distribution at the silicon periphery, it ensures stable 200V blocking across temperature and lifetime-reducing risk of localized hot spots and premature failure in automotive load-dump scenarios. This is confirmed in TSC's AEC-Q101 stress reports for the MBRF5200H.

What is the forward voltage specification for the MBRF5200H at elevated temperature?

The MBRF5200H specifies a maximum forward voltage (V_F) of 0.92 V at 5A and 125°C junction temperature, measured with 0.3ms pulse width. At 25°C, V_F is ≤1.02 V. This low, temperature-stable V_F directly reduces conduction losses in high-ambient applications-e.g., in a 12V output rail, it cuts I²R loss by ~22% versus a typical 1.15V Si diode at same current and temperature.

Is the MBRF5200H pin-compatible with other ITO-220AC Schottky rectifiers?

The MBRF5200H uses standard ITO-220AC mechanical dimensions and 3-terminal layout (Anode–Cathode–Isolated Tab), making it mechanically interchangeable with other ITO-220AC rectifiers like MBRF5100H or VS-50WQ03FN-M3/45. However, electrical compatibility requires verification of V_RRM, V_F, and thermal resistance-e.g., substituting a 100V part risks breakdown, and a higher-R_θJC part may overheat at 5A. Always validate against the full MBRF5200H datasheet before replacement.
