Product details

Overview

MBR2050PT from Taiwan Semiconductor is a 20A, 50V dual-die Schottky barrier rectifier in TO-247AD package, featuring 0.95V max forward voltage at 20A/25°C, 150A surge capability, and 1°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in DC-DC converters and switching power supplies for industrial and consumer electronics.

For engineers reviewing the MBR2050PT datasheet, MBR2050PT pinout, MBR2050PT application, or MBR2050PT equivalent, key selection criteria include its 50V repetitive peak reverse voltage, low VF at high current and temperature, AEC-Q101 qualification option (MBR2050PTH), and TO-247AD mechanical compatibility with high-power heatsink mounting.

Technical Context

This device integrates two independent Schottky diodes in a single TO-247AD package, enabling dual-channel or center-tapped rectification without paralleling discrete devices. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.

The MBR2050PT operates across –55°C to +150°C junction temperature range with 10,000 V/μs critical dV/dt rating, supporting fast-switching topologies. Thermal performance is defined by 1°C/W R_θJC, allowing direct case-to-heatsink thermal path design for sustained 20A conduction.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum repetitive reverse blocking voltage per diode; sets upper limit for output voltage in flyback or forward converters
I_F	20 A - Continuous average forward current per diode; supports high-power secondary-side rectification without derating at T_C ≤ 85°C
I_FSM	150 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overload in SMPS startup
V_F @ 20A, 25°C	0.95 V max - Low conduction loss enables >92% efficiency in 12V-output DC-DC stages at full load
R_θJC	1 °C/W - Enables predictable thermal design: 20A × (0.95V) = 19W dissipation → ΔT_JC = 19°C above heatsink
I_R @ 50V, 125°C	10 mA max - Low leakage preserves efficiency in high-temperature environments like enclosed power adapters
T_J max	+150 °C - Allows operation in thermally constrained spaces such as sealed LED drivers or industrial PSUs

Pinout & Package

Package: TO-247AD (TO-3P), 3-terminal single-in-line outline with isolated metal tab (cathode-connected case), matte tin-plated leads, UL 94V-0 molding compound, 6.10g weight, polarity marked on device body.

Pin/Terminal	Circuit Role	Design Meaning
Terminal 1 (Anode 1)	Anode of first Schottky die	Connects to transformer secondary or switch node; electrically isolated from case
Terminal 2 (Cathode)	Common cathode for both dies	Internally bonded to metal tab; must be mounted to heatsink with electrical isolation if required
Terminal 3 (Anode 2)	Anode of second Schottky die	Enables dual-anode configuration for center-tapped transformer or dual-output rectification

Key Features

Feature	Design Value
Dual-die integration in TO-247AD	Eliminates interconnect inductance and thermal mismatch between discrete 20A Schottkys; reduces PCB area by ~40% vs. two TO-220 devices
Guard ring overvoltage protection	Prevents premature avalanche breakdown under transient voltage spikes, improving reliability in unregulated input conditions
150A I_FSM rating	Supports robust operation during cold-start surges in 200W+ adapters without external current limiting
AEC-Q101 qualified variant available	MBR2050PTH meets automotive-grade stress testing for under-hood power modules and infotainment DC-DC supplies
Junction-to-case thermal resistance of 1°C/W	Permits direct thermal coupling to aluminum heatsinks without thermal interface material in many 20A applications

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	Same 20A/50V rating, TO-247AC package (non-isolated tab), 0.92V V_F max @ 20A/25°C	Lacks guard ring; lower dV/dt rating (5,000 V/μs); not AEC-Q101 qualified	Select when lowest possible V_F is prioritized and automotive qualification is unnecessary
ON Semiconductor MBR2050CT	20A/50V dual common-cathode Schottky, TO-220AB package, 0.97V V_F max @ 20A/25°C, R_θJC = 2.5°C/W	Lower thermal performance; requires larger heatsink; limited to ≤12A continuous in same footprint	Select when TO-220 mounting is mandatory and power density is secondary to cost

Compared with VS-20CPH05 and MBR2050CT, the MBR2050PT delivers superior thermal management via 1°C/W R_θJC and enhanced system reliability through integrated guard ring protection-critical for high-stress industrial and automotive-qualified designs.

FAQ

What is the maximum junction temperature rating for the MBR2050PT?

The MBR2050PT has a maximum junction temperature (T_J) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in enclosed power supplies and high-ambient environments. The device's 1°C/W junction-to-case thermal resistance enables effective heat transfer to external heatsinks, ensuring the MBR2050PT maintains safe operating temperatures even at full 20A load under proper thermal design.

Does the MBR2050PT have AEC-Q101 qualification?

The standard MBR2050PT is not AEC-Q101 qualified, but the pin-compatible variant MBR2050PTH is explicitly qualified to AEC-Q101. Both share identical electrical and thermal specifications, including 50V V_RRM, 20A I_F, and 1°C/W R_θJC. For automotive applications such as infotainment power modules or ADAS camera supplies, MBR2050PTH must be specified to meet stress-test requirements.

What is the forward voltage specification for the MBR2050PT at full rated current?

The MBR2050PT has a maximum forward voltage (V_F) of 0.95 V at 20A and 25°C junction temperature. At elevated temperature (125°C), V_F rises to 0.85 V max. These values are measured per diode under pulsed conditions (PW = 0.3ms), reflecting real-world conduction loss in high-frequency switching applications where the MBR2050PT is commonly deployed.

How is the TO-247AD package configured for thermal and electrical connection in the MBR2050PT?

The MBR2050PT uses a TO-247AD package with an electrically isolated metal tab connected internally to the common cathode terminal (Pin 2). This allows direct mechanical mounting to a heatsink without shorting the cathode, provided insulating hardware is used. The package's 1°C/W R_θJC is achieved only when the tab is properly thermally coupled-no thermal paste is strictly required, though it improves margin in high-power designs.

What does the "PT" suffix indicate in the MBR2050PT part number?

The "PT" suffix in MBR2050PT denotes Taiwan Semiconductor's standard plastic package variant in TO-247AD (TO-3P) outline, with matte tin-plated leads and RoHS-compliant, halogen-free molding compound. It distinguishes this version from tape-and-reel (e.g., MBR2050PTR) or AEC-Q101 qualified (MBR2050PTH) variants, all sharing identical die and core electrical specs but differing in packaging and qualification status.
