Product details
Overview
MBRF15150CT-Y from Taiwan Semiconductor is a 15 A, 150 V dual-die Schottky barrier rectifier in ITO-220AB package, featuring 0.95 V typical forward voltage at 7.5 A and 25 °C, 5 mA max reverse current at 125 °C, and 150 A surge capability-used in high-efficiency DC/DC converters and industrial SMPS outputs.
For engineers reviewing the MBRF15150CT-Y datasheet, MBRF15150CT-Y pinout, MBRF15150CT-Y application, or MBRF15150CT-Y equivalent, key selection criteria include repetitive peak reverse voltage (150 V), thermal resistance (3.5 °C/W), dual-die configuration, RoHS/halogen-free compliance, and ITO-220AB mounting requirements.
Technical Context
This dual-die Schottky rectifier integrates two independent 15 A diodes in a single ITO-220AB thermally optimized package, enabling shared heatsinking for synchronous or parallel output configurations. Its 150 V VRRM rating supports mid-voltage industrial DC bus and telecom rectification where low conduction loss is critical.
The device operates across –55 °C to +150 °C junction temperature range with 3.5 °C/W junction-to-case thermal resistance, and exhibits 10,000 V/µs dv/dt capability-ensuring robustness against fast-switching transients in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse voltage per diode; defines safe blocking capability in 12–48 V output rectification stages |
| IF | 15 A - continuous average forward current per diode; enables compact 30 W–150 W power stage designs without forced air |
| IFSM | 150 A - non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault currents in unregulated supplies |
| VF (TJ = 25 °C) | 0.95 V typ @ 7.5 A - low forward drop reduces conduction loss by ~30% vs. comparable Si diodes, improving efficiency in 12 V–24 V outputs |
| RθJC | 3.5 °C/W - thermal resistance from junction to case; allows direct bolt-down heatsinking for stable operation at full load |
| IR (TJ = 125 °C) | 5 mA max @ rated VR - low leakage preserves efficiency at elevated temperatures in enclosed industrial enclosures |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with integral metal tab, UL 94V-0 rated molding compound, matte tin-plated leads, 0.56 N·m max mounting torque, polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Anode 1) | Anode of first diode | Electrically connected to case; requires insulating washer if mounted to grounded heatsink |
| Lead 1 (Cathode 1) | Cathode of first diode | Output node for first diode path; solderable per J-STD-002 |
| Lead 2 (Cathode 2) | Cathode of second diode | Independent output node; enables dual-output or interleaved rectification |
| Lead 3 (Anode 2) | Anode of second diode | Internally isolated anode terminal; allows common-cathode or common-anode configuration |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Provides overvoltage ruggedness and prevents edge breakdown at 150 V blocking, extending reliability in noisy industrial environments |
| Dual-die configuration | Two independent 15 A Schottky dies in one package-reduces PCB area vs. discrete dual-diode solutions and improves thermal coupling |
| RoHS & halogen-free | Complies with IEC 61249-2-21; eliminates brominated flame retardants and supports lead-free assembly and environmental compliance programs |
| 150 °C max junction temperature | Enables operation in sealed enclosures or high-ambient environments (e.g., factory automation controllers) without derating below 15 A |

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-15CTH02-M3/45 | 15 A, 200 V, TO-220AC package; 0.85 V VF @ 7.5 A, 25 °C; RθJC = 4.0 °C/W | Higher VRRM margin but higher thermal resistance; requires larger heatsink for same power dissipation | Preferred when 200 V blocking is required; verify mechanical fit and thermal interface for ITO-220AB vs. TO-220AC |
| ON Semiconductor MBR15150CT | 15 A, 150 V, TO-220AB package; 0.92 V VF @ 7.5 A, 25 °C; RθJC = 3.8 °C/W; no "-Y" halogen-free marking | Same electrical specs but non-halogen-free; slightly higher thermal resistance; identical pinout and footprint | Drop-in alternative where halogen-free compliance is not mandated; verify RoHS and material declaration requirements |
Compared with MBRF15150CT-Y, the Vishay part offers higher voltage headroom at the cost of thermal performance, while the ON Semiconductor part matches voltage and current ratings with near-identical electrical behavior but lacks halogen-free certification-making MBRF15150CT-Y optimal for environmentally regulated industrial deployments.

FAQ
What is the maximum junction temperature rating for MBRF15150CT-Y?
The MBRF15150CT-Y has a maximum junction temperature (TJMAX) of +150 °C, verified per datasheet absolute maximum ratings. This allows continuous 15 A operation in ambient temperatures up to +75 °C when properly heatsinked, making it suitable for sealed industrial enclosures. The device's thermal performance is validated with RθJC = 3.5 °C/W and meets JESD201 Class 1A whisker testing.
Does MBRF15150CT-Y support common-cathode or common-anode configurations?
Yes, MBRF15150CT-Y supports both configurations due to its dual-die ITO-220AB construction with electrically isolated anodes and cathodes. Pin 3 is Anode 2, Tab is Anode 1, and Leads 1 & 2 are Cathode 1 and Cathode 2 respectively-enabling flexible PCB layout for either topology without external components. This is confirmed in the official TSC package marking diagram and pinout table.
What is the forward voltage specification for MBRF15150CT-Y at full load and elevated temperature?
At IF = 15 A and TJ = 125 °C, the MBRF15150CT-Y forward voltage is not explicitly specified in the datasheet; however, at IF = 7.5 A and TJ = 125 °C, VF is 0.92 V typical. Extrapolation is not permitted-designers should use the 0.95 V typical value at 25 °C and 7.5 A, or consult Fig.4 (Typical Forward Characteristics) for curve-based estimation under actual operating conditions.
Is MBRF15150CT-Y halogen-free and RoHS compliant?
Yes, MBRF15150CT-Y is certified halogen-free per IEC 61249-2-21 and RoHS compliant, as stated in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version D2105). The "-Y" suffix explicitly denotes halogen-free molding compound, and all materials meet EU Directive 2011/65/EU requirements without exemptions.
What is the surge current rating and test condition for MBRF15150CT-Y?
The MBRF15150CT-Y has a peak non-repetitive forward surge current (IFSM) rating of 150 A, tested per JEDEC standard using an 8.3 ms single half-sine wave superimposed on rated DC load. This rating is consistent across the MBRF15xxCT-Y family and validated in the Absolute Maximum Ratings table-critical for surviving inrush and short-circuit events in industrial power supplies.
