Product details
Overview
MBRF20H100CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 20A average forward current, 100V repetitive peak reverse voltage, and 150A non-repetitive surge current at 8.3ms; used in high-efficiency SMPS outputs and DC-DC converter secondary-side rectification.
For engineers reviewing the MBRF20H100CT datasheet, MBRF20H100CT pinout, MBRF20H100CT application, or MBRF20H100CT equivalent, key selection criteria include forward voltage at 10A/20A (0.85V/0.95V @ 25°C), junction-to-case thermal resistance (3.5°C/W), AEC-Q101 qualification status, and ITO-220AB mounting compatibility with heatsink interfaces.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single ITO-220AB thermally enhanced package, enabling common-cathode configuration for center-tapped transformer or synchronous rectifier topologies. Its guard ring structure provides overvoltage protection, and it sustains 175°C maximum junction temperature with 10,000 V/µs critical dv/dt rating.
The device delivers low conduction loss across operating temperatures: VF remains ≤0.85V at 10A/25°C and ≤0.95V at 20A/25°C, while reverse leakage stays ≤5µA at 25°C and ≤2mA at 125°C under rated 100V reverse bias - supporting stable performance in thermally constrained power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 20 A - supports continuous output current in 100–200W SMPS designs without forced air cooling |
| VRRM | 100 V - defines maximum reverse blocking capability for 48V-input DC-DC converters and offline auxiliary supplies |
| IFSM (8.3ms) | 150 A - withstands inrush surges during cold-start or short-circuit recovery in industrial power modules |

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-20CPH05-M3 | Same ITO-220AB package, 50V VRRM, lower VF (0.52V @ 10A), but 50% lower surge rating (75A) | Optimized for low-voltage, high-efficiency telecom supplies; unsuitable for 100V bus applications | Select only if system VR ≤50V and surge immunity is secondary to conduction loss |
| ON Semiconductor MBR20100CT | Identical 100V/20A rating and ITO-220AB package; AEC-Q101 not offered; VF slightly higher (0.88V @ 10A) | Targeted at industrial/commercial power supplies where automotive qualification is unnecessary | Preferred for cost-sensitive non-automotive designs with identical electrical and mechanical fit |
Compared with MBRF20H100CT, VS-20CPH05-M3 trades voltage capability for ultra-low VF in sub-50V systems, while MBR20100CT matches core specs without AEC-Q101 - making MBRF20H100CT the only choice when automotive-grade surge resilience and 100V blocking are jointly required.

FAQ
What is the pin configuration of the MBRF20H100CT?
The MBRF20H100CT uses a three-terminal ITO-220AB package with a common cathode on the metal tab and two independent anodes on leads 1 and 2. This configuration supports center-tapped transformer full-wave rectification and dual-output designs. The tab must be electrically isolated from chassis ground unless referenced to system cathode potential.
Is the MBRF20H100CT AEC-Q101 qualified?
The MBRF20H100CT itself is not AEC-Q101 qualified; however, the AEC-Q101 variant is designated MBRF20H100CTH. Both share identical electrical and thermal specifications, but only the 'H' suffix version undergoes automotive stress testing per AEC-Q101 Rev D. Always verify ordering code suffix when targeting automotive applications.
What is the maximum junction temperature for the MBRF20H100CT?
The MBRF20H100CT has a maximum junction temperature (TJ max) of 175°C, validated across its full operating range. This rating enables reliable operation in high-ambient environments such as engine compartments or sealed industrial enclosures, provided thermal design maintains RθJA ≤ 5.0°C/W for 20A continuous conduction.
How does the forward voltage of the MBRF20H100CT vary with temperature and current?
The MBRF20H100CT exhibits negative temperature coefficient behavior: VF drops from 0.95V @ 20A/25°C to 0.85V @ 20A/125°C. At 10A, VF is ≤0.85V at 25°C and ≤0.75V at 125°C. This improves efficiency at elevated temperatures but requires thermal-aware layout to avoid localized hot spots.
Can the MBRF20H100CT replace the MBR20100CT in existing designs?
Yes, the MBRF20H100CT is mechanically and electrically compatible with the ON Semiconductor MBR20100CT - same ITO-220AB package, 100V VRRM, 20A IF, and dual-common-cathode topology. However, MBRF20H100CT offers lower VF (0.85V vs. 0.88V @ 10A/25°C) and optional AEC-Q101 qualification (via 'H' suffix), making it a functional upgrade where tighter thermal or automotive compliance is needed.
