Product details
Overview
MBR3050CTH from Taiwan Semiconductor is a 30A, 50V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.77V max forward voltage at 15A/25°C, 200A surge capability, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency output rectifier in DC-DC converters and SMPS secondary-side circuits.
For engineers reviewing the MBR3050CTH datasheet, MBR3050CTH pinout, MBR3050CTH application, or MBR3050CTH equivalent, key selection criteria include its 50V VRRM rating, dual-common-cathode configuration, thermal resistance of 1.0°C/W (junction-to-case), and AEC-Q101 qualification status for under-hood automotive power systems.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling synchronous rectification or dual-channel output paths. Its low VF and high IFSM support high-frequency switching topologies while minimizing conduction losses and thermal stress.
The junction-to-case thermal resistance is 1.0°C/W for the 50V variant, matching MBR3035CT through MBR3060CT, and it operates across –55°C to +150°C junction temperature range with guard ring protection against transient overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in DC-DC flyback or forward converter secondary windings. |
| IF(AV) | 30 A - Average forward current per diode; supports continuous 30A output in thermally managed SMPS designs. |
| IFSM | 200 A - Non-repetitive peak surge current (8.3ms half-sine); withstands startup inrush and transient load spikes without failure. |
| VF @ 15A, 25°C | 0.77 V max - Low forward drop reduces conduction loss and improves system efficiency above 90% in 12V–48V output stages. |
| RθJC | 1.0 °C/W - Thermal resistance from junction to case; enables direct heatsink mounting for stable operation at full 30A load with ≤30°C case rise. |
| IR @ 50V, 25°C | 200 µA max - Low leakage preserves efficiency in standby mode and prevents unintended discharge in hold-up capacitor networks. |
| TJ Range | –55°C to +150°C - Wide operating junction temperature range supports under-hood automotive environments and industrial ambient conditions. |
Pinout & Package

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-30CPH05 | Same TO-220AB package, 50V VRRM, 30A IF, but rated for 175°C TJ max and lacks AEC-Q101 qualification. | Preferred for industrial high-temp environments (>150°C ambient), not recommended for automotive OEM designs requiring AEC compliance. | Select MBR3050CTH when AEC-Q101 validation and guaranteed 150°C operation are mandatory; choose VS-30CPH05 only if higher TJ rating outweighs qualification requirements. |
| ON Semiconductor MBR3050CT | Identical electrical specs and TO-220AB package, but non-AEC-Q101 version; same VF, IFSM, and thermal resistance. | Suitable for commercial/industrial SMPS where automotive qualification is unnecessary; lower cost and broader distribution. | Choose MBR3050CTH over MBR3050CT exclusively when automotive-grade reliability, traceability, and stress-test validation are required per OEM Tier-1 specifications. |
Compared with VS-30CPH05 and MBR3050CT, the MBR3050CTH uniquely combines AEC-Q101 qualification, 150°C junction rating, and verified 1.0°C/W thermal performance-making it the only option qualified for safety-critical automotive power conversion without design revalidation.

FAQ
What does the "H" suffix in MBR3050CTH signify?
The "H" suffix in MBR3050CTH indicates full AEC-Q101 qualification, including stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life. This certification confirms that the MBR3050CTH meets automotive-grade reliability standards for use in engine control, ADAS, and body electronics applications where zero-defect performance is mandated.
Is MBR3050CTH pin-compatible with MBR3050CT?
Yes, MBR3050CTH is mechanically and electrically pin-compatible with MBR3050CT-same TO-220AB package, identical pinout (Anode1–Cathode–Anode2), and matching absolute maximum ratings. The only difference is AEC-Q101 qualification and associated test documentation; no PCB or schematic changes are needed when upgrading from MBR3050CT to MBR3050CTH.
What is the maximum continuous forward current per diode in MBR3050CTH?
The MBR3050CTH supports 30A average forward current per diode at TC = 85°C with adequate heatsinking. At TC = 100°C, derating applies per the forward current derating curve; full 30A operation requires case temperature ≤85°C. The dual-die structure maintains this rating independently for each anode path under balanced loading conditions.
Does MBR3050CTH have a guard ring, and what function does it serve?
Yes, MBR3050CTH incorporates a guard ring structure around each die to prevent edge breakdown during high dv/dt transients. This feature enables reliable operation at 10,000 V/μs critical rate of rise, protecting against voltage overshoot in fast-switching SMPS and motor drive inverters without requiring external snubbers or clamping circuits.
What is the typical forward voltage of MBR3050CTH at 30A and 125°C?
Per the datasheet, the MBR3050CTH exhibits a typical forward voltage of ≤0.73V at IF = 30A and TJ = 125°C. This low, temperature-stable VF ensures minimal conduction loss and predictable thermal behavior in high-ambient environments such as under-hood automotive applications or enclosed industrial enclosures.
