Product details
Overview
MBR20150CT-Y from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-220AB package with 150V repetitive peak reverse voltage (VRRM), 150A surge current rating (IFSM), and 2°C/W junction-to-case thermal resistance, designed for high-efficiency DC–DC converters and switching power supplies.
For engineers reviewing the MBR20150CT-Y datasheet, MBR20150CT-Y pinout, MBR20150CT-Y application, or MBR20150CT-Y equivalent, key selection criteria include forward voltage at 20A/125°C (1.10 V max), reverse leakage at 150V/125°C (5 mA max), thermal performance under forced-air or heatsink mounting, and compatibility with SMPS topologies requiring low-loss bidirectional conduction.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB package with common-cathode configuration, enabling synchronous rectification or dual-output DC–DC designs. Its 150V VRRM rating supports mid-voltage industrial and telecom power rails, while the 2°C/W RθJC enables thermal management up to 20A continuous operation with appropriate heatsinking.
The MBR20150CT-Y exhibits temperature-dependent forward voltage behavior-1.23 V max at 20A/25°C and 1.10 V max at 20A/125°C-and reverse leakage tightly specified at 5 mA max per diode at rated VRRM and TJ = 125°C, critical for maintaining efficiency in high-temperature environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per diode; defines usable input/output voltage range in buck, flyback, or OR-ing applications. |
| IF | 20 A - Continuous forward current per diode; determines minimum trace width and heatsink sizing for steady-state conduction loss. |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush current handling during startup or fault transients. |
| VF @ 20A/125°C | 1.10 V max - Forward voltage drop under worst-case thermal and load conditions; directly impacts conduction loss and thermal design margin. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables calculation of maximum case temperature rise above ambient for given power dissipation. |
| IR @ 150V/125°C | 5 mA max - Reverse leakage per diode at full rated voltage and elevated temperature; affects standby power and cross-conduction risk in synchronous designs. |
Pinout & Package
Package: TO-220AB, 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, and polarity marked on body. Mounting torque ≤ 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first Schottky diode; connects to switching node or input rail in half-bridge or dual-output configurations. |
| Pin 2 (Center) | Cathode (Common) | Shared cathode connection for both diodes; serves as output or return path; must be thermally coupled to heatsink. |
| Pin 3 (Right) | Anode 2 | Input terminal for second Schottky diode; enables independent control or parallel operation with Anode 1. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage at high temperature | 1.10 V max at 20A/125°C reduces conduction loss by ~15% vs. standard silicon rectifiers in hot-running SMPS. |
| Dual-die common-cathode configuration | Enables compact dual-output rectification or redundant OR-ing without external interconnects or layout duplication. |
| Guard ring overvoltage protection | Improves ruggedness against transient voltage spikes in unregulated input stages or inductive load switching. |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives; suitable for export-controlled and environmentally regulated industrial products. |
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-MBR20150CT | Same 20A/150V rating, TO-220AB package, but VF = 1.15 V max @ 20A/125°C; RθJC = 2.2 °C/W. | Slightly higher conduction loss and thermal resistance; acceptable where 0.05 V VF margin is available. | Select when Vishay supply chain alignment or legacy qualification is required; verify heatsink derating. |
| ON Semiconductor MBR20150CTG | Identical electrical specs and TO-220AB mechanical outline; RoHS-compliant but not halogen-free per IEC 61249-2-21. | No functional difference in circuit operation; may require requalification if halogen-free compliance is mandatory. | Prefer for cost-sensitive industrial designs where halogen-free status is not enforced. |
Compared with MBR20150CT-Y, the VS-MBR20150CT trades 0.05 V higher VF and +0.2 °C/W thermal resistance for broader distributor availability, while the MBR20150CTG matches all electrical parameters but omits halogen-free certification-making MBR20150CT-Y optimal for environmentally regulated deployments.

FAQ
What is the maximum junction temperature rating for MBR20150CT-Y?
The MBR20150CT-Y has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version B2104. This rating allows operation in high-ambient environments such as enclosed server PSUs or industrial enclosures, provided thermal design maintains junction temperature below this limit using the specified 2°C/W RθJC and appropriate heatsinking. Exceeding +150°C risks parametric shift and long-term reliability degradation.
Does MBR20150CT-Y support common-cathode or common-anode configuration?
The MBR20150CT-Y uses a common-cathode configuration: Pin 2 (center tab) is the shared cathode, while Pins 1 and 3 are independent anodes. This is confirmed in the device marking diagram and package outline documentation. It is not configurable as common-anode; attempting reverse connection violates absolute maximum ratings and may cause immediate failure due to reverse breakdown of the internal guard ring structure.
What is the forward voltage specification for MBR20150CT-Y at 20A and 125°C?
The forward voltage for MBR20150CT-Y is specified as 1.10 V maximum at 20A forward current and 125°C junction temperature, per Electrical Specifications table on page 3 of the Taiwan Semiconductor datasheet (Version B2104). This value reflects worst-case conduction loss under thermal stress and is critical for calculating power dissipation (PCOND ≈ 1.10 V × 20 A = 22 W) and verifying thermal margin with the 2°C/W RθJC.
Is MBR20150CT-Y halogen-free and RoHS compliant?
Yes, MBR20150CT-Y is both RoHS compliant and halogen-free according to IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound contains no brominated or chlorinated flame retardants, and lead content meets EU RoHS Directive 2011/65/EU limits. This makes it suitable for export to EU, Japan, and other regions enforcing strict chemical substance restrictions.
What is the reverse leakage current of MBR20150CT-Y at full rated voltage and high temperature?
At 150V reverse voltage and 125°C junction temperature, the MBR20150CT-Y exhibits a maximum reverse leakage current (IR) of 5 mA per diode, as specified in the ELECTRICAL SPECIFICATIONS table (page 3, Version B2104). This value is measured under 30ms pulse conditions and is critical for evaluating standby power loss and cross-conduction risk in synchronous rectifier circuits operating near thermal limits.
