Product details
Overview
MBR15150CT-Y from Taiwan Semiconductor is a 15 A, 150 V dual-die Schottky barrier rectifier in TO-220AB package, featuring 1.05 V forward voltage at 7.5 A and 25°C, 150 A surge capability, 1.5 °C/W junction-to-case thermal resistance, and guard ring overvoltage protection-used in high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the MBR15150CT-Y datasheet, MBR15150CT-Y pinout, MBR15150CT-Y application, or MBR15150CT-Y equivalent, key selection criteria include repetitive peak reverse voltage (150 V), forward voltage at rated current, thermal resistance, surge rating, and TO-220AB mounting compatibility with heatsink interfaces.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-220AB case with common cathode configuration (CT), enabling full-wave rectification without external parallel diodes. Its low forward voltage and fast recovery support high-frequency switching topologies.
The device operates across -55°C to +150°C junction temperature range, with 10 °C/W junction-to-ambient thermal resistance under standard PCB mount conditions and 1.5 °C/W junction-to-case resistance for direct heatsink attachment-critical for thermal management in compact power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage headroom in AC/DC or DC/DC stages. |
| IF | 15 A - Continuous average forward current per diode; determines steady-state conduction capacity in rectifier bridges or output stages. |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush current handling during power-up or fault transients. |
| VF @ 7.5A, 25°C | 1.05 V - Forward voltage drop per diode at half-rated current; directly impacts conduction loss and thermal design in high-efficiency converters. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing when mounted with thermal interface material. |
| IR @ 150V, 25°C | 100 µA - Reverse leakage per diode at rated VR; low value minimizes standby power loss in offline adapters. |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for thermal derating curves and reliability margin. |
Pinout & Package
Package: TO-220AB, 3-terminal plastic case with isolated tab, matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on body.

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-15CTQ015 | 15 A, 150 V, VF = 0.82 V @ 7.5 A, 25°C; RθJC = 1.7 °C/W; TO-220AC package (isolated tab). | Lower VF improves light-load efficiency but higher thermal resistance requires larger heatsink area. | Select when lowest conduction loss dominates thermal budget constraints. |
| ON Semiconductor MBR15150CT | Identical electrical specs and TO-220AB package; differs only in date-code marking suffix (no -Y), RoHS compliance level. | No functional difference; suitable for legacy BOM migration where -Y suffix not mandated. | Choose for cost-sensitive volume production where green compound requirement is waived. |
Compared with MBR15150CT-Y, VS-15CTQ015 offers lower forward voltage but less favorable thermal resistance, while MBR15150CT matches all critical parameters except marking and environmental compliance-making it a drop-in alternative only where halogen-free and RoHS-2 certification are not required.

FAQ
What is the maximum junction temperature rating for MBR15150CT-Y?
The MBR15150CT-Y has a maximum junction temperature (TJ max) of +150°C, verified per TSC's D2104 datasheet revision. This rating allows operation in high-temperature environments such as enclosed server PSUs or automotive under-hood auxiliary supplies. Derating curves in the datasheet define safe IF reduction above 100°C ambient, and thermal design must respect the 1.5 °C/W RθJC to avoid exceeding TJ max under full load. MBR15150CT-Y must be mounted with appropriate thermal interface to maintain reliability.
Is MBR15150CT-Y pin-compatible with other parts in the MBR15xxCT-Y family?
Yes, all MBR15xxCT-Y variants-including MBR1545CT-Y, MBR1560CT-Y, MBR15100CT-Y, MBR15150CT-Y, and MBR15200CT-Y-share identical TO-220AB package dimensions, pinout (Anode1–Cathode–Anode2), and mechanical mounting features. The only differences are VRRM rating and corresponding forward voltage characteristics. MBR15150CT-Y can be substituted within the same footprint without PCB changes, provided voltage and thermal margins are validated.
Does MBR15150CT-Y have a common-cathode or common-anode configuration?
MBR15150CT-Y uses a common-cathode (CT) configuration: Pin 2 (center lead) and the metal tab are internally connected to the shared cathode node, while Pins 1 and 3 serve as independent anodes. This enables full-wave rectification from center-tapped transformers or complementary switching nodes. The configuration is explicitly defined in the "Configuration" line of the datasheet and confirmed by the marking diagram showing cathode-side polarity indicators. MBR15150CT-Y is not suitable for common-anode topologies without circuit redesign.
What is the reverse leakage current specification for MBR15150CT-Y at 125°C?
At 125°C junction temperature and rated 150 V reverse voltage, the MBR15150CT-Y exhibits a maximum reverse leakage current (IR) of 5 mA per diode, as specified in the Electrical Specifications table under "Reverse current @ rated VR per diode". This value is measured using a 30 ms pulse test and reflects worst-case thermal stress in high-temperature applications like industrial motor drives. Designers must account for this leakage in standby power budgets and thermal runaway analysis. MBR15150CT-Y maintains stable leakage behavior up to its 150°C TJ limit.
Can MBR15150CT-Y be used in surface-mount designs?
No, MBR15150CT-Y is exclusively offered in the through-hole TO-220AB package and is not available in surface-mount variants such as D²PAK or SO-20. Its mechanical data specify mounting torque (0.56 N·m max), heatsink interface requirements, and lead-forming guidelines-all oriented toward vertical PCB insertion and screw-down heatsinking. Attempting reflow soldering or SMT placement would damage the package and void specifications. For SMT alternatives, consider TSC's MBR20150CTM (TO-263) or equivalent SMD Schottky arrays. MBR15150CT-Y requires through-hole assembly.
