Product details
Overview
MBR25150CT-Y from Taiwan Semiconductor is a 25A, 150V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.95V forward voltage at 12.5A/25°C and 5µA reverse leakage at 150V/125°C, used in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR25150CT-Y datasheet, MBR25150CT-Y pinout, MBR25150CT-Y application, or MBR25150CT-Y equivalent, key selection criteria include VRRM=150V, IF=25A, IFSM=200A, VF≤1.02V at 25A/25°C, and RθJC=1°C/W thermal resistance for thermal-limited power supply designs.
Technical Context
This dual-die Schottky rectifier integrates two independent 150V/25A diodes in a single TO-220AB case with common-cathode configuration. Its guard ring structure provides overvoltage protection, and it sustains 200A non-repetitive surge current per diode under 8.3ms half-sine conditions.
Designed for high-frequency switching applications, it delivers low conduction loss (VF ≤ 0.92V at 25A/125°C) and fast recovery (no stored charge), with junction-to-case thermal resistance of 1°C/W enabling high-power density layouts without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage each diode withstands without breakdown |
| IF | 25 A - Continuous average forward current per diode at TC = 100°C |
| IFSM | 200 A - Peak non-repetitive surge current per diode (8.3ms half-sine) |
| VF @ 12.5A/25°C | 0.95 V - Forward voltage drop per diode, directly determining conduction loss in 12V–48V output rails |
| IR @ 150V/125°C | 5 µA - Reverse leakage per diode, critical for standby power and high-temperature reliability |
| RθJC | 1 °C/W - Junction-to-case thermal resistance, enabling 25W dissipation with ≤25°C case-to-ambient delta |
Pinout & Package
Package: TO-220AB, 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab / Pin 1 | Anode 1 | First diode anode; electrically connected to metal tab - requires isolation when mounted to heatsink |
| Pin 2 | Cathode (common) | Shared cathode node for both diodes - primary current return path in center-tap or dual-output configurations |
| Pin 3 | Anode 2 | Second diode anode; independent from Pin 1 - enables dual-output or interleaved rectification |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Enhances ruggedness against transient voltage spikes in unregulated input stages without external snubbers |
| Low VF at high temperature | 0.92V @ 25A/125°C ensures stable efficiency in thermally constrained enclosures |
| High IFSM capability | 200A surge rating supports inrush current handling in offline AC-DC front-ends |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and J-STD-002 solderability standards for lead-free assembly |

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-25CPH15 | Same TO-220AB package, 25A/150V, VF = 0.97V @ 25A/25°C, RθJC = 1.2°C/W | Slightly higher thermal resistance; lower surge rating (175A vs. 200A) | Preferred where Vishay qualification or alternate sourcing is required; verify thermal margin at full load |
| ON Semiconductor MBR25150CT | Identical electrical specs and TO-220AB package; differs only in date-code marking suffix (-Y vs. blank) | No functional difference; same pinout, thermal, and reliability performance | Drop-in alternative if -Y suffix not mandated by procurement policy or traceability requirements |
Compared with MBR25150CT-Y, VS-25CPH15 offers comparable voltage/current ratings but requires thermal derating due to higher RθJC, while MBR25150CT is functionally identical except for marking - making it a seamless substitution where suffix compliance is not enforced.

FAQ
What is the maximum junction temperature rating for MBR25150CT-Y?
The MBR25150CT-Y has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial power supplies. Derating curves confirm 25A continuous current is sustainable up to TC = 100°C, and the device must be heatsinked to maintain TJ ≤ 150°C under full load.
Is MBR25150CT-Y a common-cathode or common-anode configuration?
The MBR25150CT-Y uses a common-cathode configuration: Pin 2 is the shared cathode terminal, while Pins 1 and 3 are independent anodes. This is confirmed by the TO-220AB pinout diagram and electrical test setup in the datasheet, enabling dual-output or center-tapped transformer rectification without external wiring.
Does MBR25150CT-Y meet lead-free soldering standards?
Yes, MBR25150CT-Y features matte tin-plated leads compliant with J-STD-002 for lead-free soldering, and its molding compound is halogen-free per IEC 61249-2-21. The device is RoHS-compliant and rated for reflow profiles up to 260°C peak, with no special pre-conditioning required.
What is the reverse leakage current of MBR25150CT-Y at full rated voltage and elevated temperature?
At VR = 150V and TJ = 125°C, the MBR25150CT-Y exhibits a maximum reverse leakage current (IR) of 5 µA per diode, as specified in the Electrical Specifications table. This low leakage supports energy-efficient standby modes in telecom and server power systems where input ripple and quiescent loss are tightly controlled.
Can MBR25150CT-Y replace MBR25100CT-Y in a design?
MBR25150CT-Y can replace MBR25100CT-Y only if the circuit's reverse voltage stress remains ≤150V - the higher VRRM adds margin but does not degrade performance. However, VF increases slightly (0.95V vs. 0.85V at 12.5A/25°C), so conduction loss rises ~12%; thermal validation is recommended before substitution in thermally constrained layouts.
