Product details

Overview

MBR2050CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package, rated for 20A average forward current, 50V repetitive peak reverse voltage, and 150A non-repetitive surge current; it delivers low forward voltage (0.80 V typ. @ 10A, 25°C) and operates up to 150°C junction temperature, targeting high-efficiency DC/DC converters and automotive-grade power supplies.

For engineers reviewing the MBR2050CTH datasheet, MBR2050CTH pinout, MBR2050CTH application, or MBR2050CTH equivalent, key selection criteria include its AEC-Q101 qualification, 50V V_RRM, dual-common-cathode configuration, thermal resistance of 1°C/W (junction-to-case), and 10 mA max reverse leakage at 125°C - all critical for under-hood SMPS and industrial adapter designs requiring robust thermal performance and automotive reliability.

Technical Context

This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling synchronous rectification or dual-output configurations. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.

The MBR2050CTH exhibits a typical forward voltage of 0.70 V at 10A and 125°C, and maintains ≤10 mA reverse leakage up to 125°C - confirming stable operation in thermally demanding environments. Its 10,000 V/μs critical dv/dt rating supports fast-switching topologies without spurious turn-on.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - maximum blocking voltage per diode; defines safe operating range in 48V bus or 36V input DC/DC stages
I_F	20 A - continuous average forward current; supports high-power output rails without forced air cooling
I_FSM	150 A - 8.3 ms half-sine surge rating; withstands inrush and transient overload events in power adapters
V_F (10A, 25°C)	0.80 V typ. - low conduction loss improves efficiency >92% in 12V–24V output converters
R_θJC	1 °C/W - enables direct heatsink mounting with predictable thermal rise (e.g., +20°C rise at 20W dissipation)
I_R (125°C)	10 mA max - low leakage preserves standby efficiency and prevents thermal runaway in high-temp environments
T_J max	150 °C - extended junction rating allows operation in under-hood automotive locations without derating

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-MBR2050CTH	Identical electrical specs, same TO-220AB package, AEC-Q101 qualified; minor variation in marking layout and date code format	No functional difference; accepted as second source by Tier-1 automotive suppliers	Select when dual-sourcing is required for supply chain resilience without redesign
ON Semiconductor MBR2050CT	Lacks AEC-Q101 qualification; otherwise matches V_RRM, I_F, V_F, and R_θJC; same pinout and footprint	Suitable for industrial/commercial use only; not approved for automotive under-hood deployment	Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated

Compared with MBR2050CTH, the Vishay alternative offers identical automotive qualification and form-fit-function compatibility, while the ON Semiconductor version trades qualification for lower unit cost in non-automotive settings - enabling tiered sourcing based on end-equipment certification needs.

FAQ

What does the "H" suffix in MBR2050CTH signify?

The "H" suffix in MBR2050CTH indicates full AEC-Q101 qualification, meaning the device has passed stress tests for automotive-grade reliability including temperature cycling, humidity bias, and high-temperature operating life. This distinguishes MBR2050CTH from the non-qualified MBR2050CT variant and confirms suitability for under-hood and safety-critical power systems.

Is MBR2050CTH pin-compatible with MBR2050CT?

Yes, MBR2050CTH is fully pin-compatible with MBR2050CT - both use identical TO-220AB packaging, shared cathode pinout (Anode1–Cathode–Anode2), and mechanical dimensions. The only functional difference is AEC-Q101 qualification; no PCB layout change is needed when upgrading from MBR2050CT to MBR2050CTH.

What is the thermal resistance from junction to case for MBR2050CTH?

The junction-to-case thermal resistance (R_θJC) for MBR2050CTH is 1°C/W, measured under standard test conditions. This value applies to both diodes in the dual-die package and assumes proper mechanical mounting of the metal tab to an external heatsink using ≤0.56 N·m torque - enabling precise thermal modeling for 20A continuous operation.

Does MBR2050CTH support dual-output power supply designs?

Yes, MBR2050CTH supports dual-output designs via its dual-anode/common-cathode configuration. Each anode operates independently, allowing separate transformer secondaries or split-rail outputs to share a common return path - commonly used in 12V/5V or ±15V industrial SMPS where tight cross-regulation and low EMI are required.

What is the maximum reverse leakage current for MBR2050CTH at 125°C?

The maximum reverse leakage current (I_R) for MBR2050CTH at rated V_RRM = 50 V and T_J = 125°C is 10 mA per diode, as specified in the Electrical Specifications table. This low leakage ensures stable operation in high-temperature environments such as automotive engine bays or enclosed industrial enclosures without thermal runaway risk.
