Product details
Overview
MBRS20150CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20 A average forward current, 150 V repetitive peak reverse voltage, and 150 A non-repetitive surge current. It operates up to 150°C junction temperature and serves as a high-efficiency output rectifier in high-frequency DC/DC converters.
For engineers reviewing the MBRS20150CT datasheet, MBRS20150CT pinout, MBRS20150CT application, or MBRS20150CT equivalent, key selection criteria include its 1.23 V forward voltage at 20 A / 25°C, 5 mA reverse leakage at 150 V / 125°C, 2.0 °C/W junction-to-case thermal resistance, and D2PAK-compatible layout for high-power density SMPS designs.
Technical Context
The MBRS20150CT integrates two independent Schottky diodes in a common-cathode configuration within a single TO-263AB thermally enhanced surface-mount package. Its 150 V VRRM rating targets mid-to-high voltage DC/DC stages where low conduction loss and fast switching are critical.
Thermal performance is defined by RθJC = 2.0 °C/W, enabling direct heatsinking via the exposed cathode tab. Electrical behavior is characterized by soft reverse recovery, <100 µA IR at 25°C, and VF drift of only +0.23 V from 25°C to 125°C at 20 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum blocking voltage before avalanche; sets upper limit for input/output voltage rails in isolated flyback or forward converters |
| IF(AV) | 20 A - Continuous DC forward current capability; supports ≥200 W output power with appropriate thermal design |
| IFSM | 150 A - Peak surge withstand for 8.3 ms half-sine; handles startup inrush and transient overloads without failure |
| VF @ 20A, 25°C | 1.23 V - Forward conduction loss per diode; determines ~24.6 W total resistive dissipation at full load |
| RθJC | 2.0 °C/W - Thermal resistance from junction to case; enables ≤30°C temperature rise above heatsink at 20 A with 60°C/W system thermal path |
| IR @ 150V, 125°C | 5 mA - Reverse leakage current at max rated voltage and temperature; impacts standby power and thermal runaway risk in parallel configurations |
Pinout & Package
Package: TO-263AB (D2PAK), thermally enhanced surface-mount outline with exposed cathode pad for PCB heatsinking. Dimensions comply with JEDEC MO-211 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode | Connects to transformer secondary or switch node; requires low-inductance routing to minimize ringing |
| Pin 2 (Anode B) | Anode of second diode | Independent anode terminal; enables dual-output or interleaved rectification topologies |
| Pin 3 (Cathode) | Common cathode | Exposed metal tab - must be soldered to large copper pour for thermal management and EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents edge breakdown at high VRRM, ensuring stable 150 V operation across manufacturing lot and temperature |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without special handling |
| Halogen-free compound (IEC 61249-2-21) | Meets environmental compliance for industrial and telecom equipment without compromising flame retardancy (UL 94V-0) |
| Matte tin-plated leads | Ensures reliable solder wetting and intermetallic formation per J-STD-002; prevents dewetting during multiple reflow cycles |

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-MBR20150CT | Identical 20 A / 150 V rating, same TO-263AB package, but RθJC = 1.8 °C/W and VF = 1.20 V @ 20 A / 25°C | Slightly lower thermal resistance and forward drop; preferred where board space limits heatsink area | Select VS-MBR20150CT when thermal budget is tighter and 0.03 V lower VF justifies potential cost or lead-time trade-off |
| ON Semiconductor MBR20150CT | Same electrical ratings and package, but specified with 10 mA IR @ 150 V / 125°C (vs. 5 mA for MBRS20150CT) | Higher leakage may impact standby power in always-on auxiliary supplies | Choose MBR20150CT only if qualification history with ON Semi is required; otherwise MBRS20150CT offers superior high-temp leakage performance |
Compared with VS-MBR20150CT and MBR20150CT, the MBRS20150CT delivers the lowest reverse leakage at elevated temperature-critical for energy-efficient standby modes-while maintaining competitive thermal and conduction performance in TO-263AB footprint.

FAQ
What is the maximum junction temperature rating for the MBRS20150CT?
The MBRS20150CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive auxiliary supplies, provided thermal design maintains junction temperature below this limit. Derating curves confirm usable current down to 0 A at 150°C case temperature.
Does the MBRS20150CT support automated SMT placement?
Yes, the MBRS20150CT is designed for automated placement per its mechanical data: it features matte tin-plated leads compliant with J-STD-002, moisture sensitivity level 1 (no baking required), and TO-263AB outline optimized for pick-and-place accuracy. The device's 1.37 g weight and symmetrical lead geometry further ensure stable feeding and placement yield.
What is the forward voltage of the MBRS20150CT at full load and elevated temperature?
At 20 A forward current and 125°C junction temperature, the MBRS20150CT exhibits a maximum forward voltage of 1.10 V per diode. This value is specified in the electrical characteristics table and reflects real-world conduction loss under sustained high-temperature operation, directly impacting thermal design and efficiency calculations.
Is the MBRS20150CT halogen-free and RoHS compliant?
Yes, the MBRS20150CT uses a halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant. These attributes are explicitly stated in the FEATURES section and confirmed in the mechanical data, making it suitable for environmentally regulated end equipment including EU-based industrial and telecom systems.
How does the guard ring feature benefit the MBRS20150CT in high-voltage applications?
The guard ring in the MBRS20150CT prevents premature edge breakdown at the silicon periphery, ensuring stable 150 V reverse blocking capability across process variation and temperature. This structural enhancement improves reliability in high dv/dt environments-such as LLC resonant converters-where localized electric field concentration could otherwise cause early failure.
