Product details
Overview
MBRF30100CT from Taiwan Semiconductor is a 30A dual common-cathode Schottky barrier rectifier with 100V repetitive peak reverse voltage (VRRM), 200A surge current rating (IFSM), and 4°C/W junction-to-case thermal resistance - designed for high-efficiency DC/DC converters and industrial switching power supplies where low forward voltage drop and fast recovery are critical.
For engineers reviewing the MBRF30100CT datasheet, MBRF30100CT pinout, MBRF30100CT application, or MBRF30100CT equivalent, key selection criteria include its ITO-220AB package, 0.94V max forward voltage at 30A/25°C, 10mA max reverse leakage at 100V/125°C, AEC-Q101 qualification option (H suffix), and dual-die configuration enabling compact full-wave rectification without external paralleling.
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package with common cathode connection, supporting full-wave rectification in offline SMPS and isolated DC/DC topologies. Its 10,000 V/µs dv/dt rating ensures robustness against voltage transients in high-frequency switching environments.
The MBRF30100CT operates across –55°C to +150°C junction temperature range and delivers stable performance up to 30A average forward current with derating above 75°C case temperature, enabled by low RθJC = 4°C/W and matte tin-plated leads compliant with J-STD-002 solderability standards.

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-30CPH0100 | Same ITO-220AB package, 100V VRRM, but 0.88V VF max @ 30A/25°C; no AEC-Q101 option listed | Lower conduction loss, but lacks automotive qualification; preferred for cost-sensitive industrial designs | Select when maximum efficiency at room temperature is prioritized and automotive qualification is not required |
| ON Semiconductor MBR30H100CT | 100V VRRM, 30A IF, AEC-Q101 qualified; VF = 0.92V max @ 30A/25°C; same ITO-220AB package | Direct AEC-Q101 alternative with tighter VF spec; identical thermal and mechanical specs | Preferred for automotive applications requiring documented AEC-Q101 compliance and traceable lot history |
Compared with MBRF30100CT, VS-30CPH0100 offers marginally lower VF but no automotive qualification, while MBR30H100CT matches AEC-Q101 support and improves VF consistency - making it suitable for mission-critical automotive auxiliary supplies where qualification and thermal stability are non-negotiable.

FAQ
What is the maximum junction temperature rating for MBRF30100CT?
The MBRF30100CT has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range allows deployment in harsh environments such as industrial motor drives and automotive under-hood applications. Thermal design must ensure that actual junction temperature remains within this limit using the specified RθJC = 4°C/W and appropriate heatsinking. The MBRF30100CT datasheet confirms this rating applies across all operating conditions unless otherwise noted.
Does MBRF30100CT support automotive applications?
Yes - an AEC-Q101 qualified version of MBRF30100CT is available as MBRF30100CTH (with 'H' suffix). This variant undergoes stress testing per AEC-Q101 standards for failure mechanisms including HTGB, HTRB, and temperature cycling. The standard MBRF30100CT is not AEC-Q101 qualified; only the 'H' suffix part meets automotive reliability requirements. Always verify ordering code and packaging markings before automotive use.
What is the forward voltage specification for MBRF30100CT at full rated current?
At 30A average forward current and 25°C junction temperature, the MBRF30100CT has a maximum forward voltage (VF) of 0.94V per diode. At 125°C junction temperature, VF max is 0.82V - demonstrating improved conduction behavior at elevated temperatures due to Schottky physics. These values are measured under pulsed conditions (PW = 0.3ms) and define worst-case conduction loss for thermal modeling of the MBRF30100CT.
How is the pinout configured for MBRF30100CT in the ITO-220AB package?
The MBRF30100CT uses a three-terminal ITO-220AB package with Pin 1 = Anode 1, Pin 2 = Common Cathode, and Pin 3 = Anode 2. The cathode tab is internally connected to Pin 2 and electrically isolated from the mounting surface. Polarity is marked on the device body per datasheet diagram. This configuration enables full-wave rectification with shared cathode output, reducing PCB trace count versus discrete dual-diode solutions.
What is the reverse leakage current of MBRF30100CT at elevated temperature?
At rated reverse voltage (100V) and 125°C junction temperature, the MBRF30100CT exhibits a maximum reverse leakage current (IR) of 10mA per diode. At 25°C and 100V, leakage is limited to 200µA max. This temperature-dependent behavior is typical of Schottky diodes and must be accounted for in high-temperature designs - especially in battery-powered or sealed enclosures where self-heating may elevate TJ beyond ambient.
