Product details
Overview
MBRF20150CT-Y from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 20A average forward current, 150V repetitive peak reverse voltage (VRRM), and 150A non-repetitive surge current (IFSM), used in high-efficiency DC–DC converters and switching power supplies where low forward voltage drop and thermal robustness are critical.
For engineers reviewing the MBRF20150CT-Y datasheet, MBRF20150CT-Y pinout, MBRF20150CT-Y application, or MBRF20150CT-Y equivalent, key selection criteria include verified VRRM = 150 V, VF = 0.95 V @ 10 A / 25°C, IR = 2 mA @ 150 V / 125°C, RθJC = 3.5 °C/W, and ITO-220AB mechanical compatibility with heatsink-mounting requirements.
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package, enabling center-tap or dual-output rectification topologies without discrete mounting. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.
The MBRF20150CT-Y operates across –55°C to +150°C junction temperature range, supports 10,000 V/µs dv/dt rating, and delivers stable reverse leakage (IR ≤ 2 mA at 125°C) - critical for maintaining efficiency in high-temperature SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage per diode; defines usable input voltage headroom in offline or boost-stage rectification |
| IF(AV) | 20 A - continuous average forward current per diode; determines steady-state power handling without forced cooling |
| VF @ 10A, 25°C | 0.95 V - forward voltage drop per diode; directly impacts conduction loss and thermal rise in high-current paths |
| IFSM | 150 A - 8.3 ms half-sine surge rating; enables reliable startup and transient overload tolerance |
| RθJC | 3.5 °C/W - junction-to-case thermal resistance; quantifies heat transfer efficiency to heatsink under mounted conditions |
| IR @ 150V, 125°C | 2 mA - maximum reverse leakage per diode; limits standby power loss and thermal runaway risk at elevated temperature |
| TJ max | +150 °C - absolute maximum junction temperature; sets upper boundary for thermal design margin |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with integral metal tab for direct heatsink mounting; UL 94V-0 rated molding compound; 1.70 g typical weight; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |

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-20CPH15 | VRRM = 150 V, IF = 20 A, VF = 0.89 V @ 10 A / 25°C, TO-247AC package, RθJC = 2.5 °C/W | Lower thermal resistance but larger footprint; requires different mounting hardware and PCB cutout | Preferred when thermal performance outweighs board space constraints and TO-247 heatsinks are already standardized |
| ON Semiconductor MBR20150CT | VRRM = 150 V, IF = 20 A, VF = 0.92 V @ 10 A / 25°C, same ITO-220AB package, RoHS-compliant but not halogen-free | Identical mechanical fit and pinout; differs in halogen-free status and minor VF/IR spread | Drop-in replacement if halogen-free requirement is not enforced; verify IR spec at 125°C for high-temp designs |
Compared with MBRF20150CT-Y, VS-20CPH15 offers better thermal performance but demands PCB redesign, while MBR20150CT provides identical form-factor compatibility with slightly tighter electrical tolerances but lacks halogen-free certification - making MBRF20150CT-Y optimal for space-constrained, environmentally regulated industrial systems.

FAQ
What is the maximum junction temperature rating for MBRF20150CT-Y?
The MBRF20150CT-Y has a maximum junction temperature (TJ max) of +150°C, validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation at full 20 A load under appropriate heatsinking. Derating curves confirm usable current down to 0 A at +150°C case temperature. Thermal design must respect RθJC = 3.5 °C/W to avoid exceeding this limit in real-world applications.
Is MBRF20150CT-Y pin-compatible with other parts in the MBRF20xxCT-Y family?
Yes, all MBRF20xxCT-Y variants - including MBRF2045CT-Y, MBRF20100CT-Y, and MBRF20200CT-Y - share identical ITO-220AB package dimensions, pinout, and terminal assignments. The only differences are VRRM rating and associated electrical parameters like VF and IR. This enables direct substitution during design iteration or voltage-scaling without PCB changes.
Does MBRF20150CT-Y have a center-tap configuration?
No, MBRF20150CT-Y uses a shared-anode dual-diode configuration: the metal tab serves as the common anode for both diodes, while leads 1 and 2 are independent cathodes. It is not a center-tapped device - that topology requires three terminals (two anodes + one shared cathode). This configuration supports dual-output or parallel-cathode rectification, not center-tap transformer interfaces.
What is the forward voltage drop of MBRF20150CT-Y at 20 A and 125°C?
Per the Taiwan Semiconductor datasheet, the MBRF20150CT-Y exhibits a forward voltage drop (VF) of 1.05 V at 20 A and 25°C, and 0.95 V at 20 A and 125°C. This negative temperature coefficient improves thermal stability under load, reducing conduction loss as junction temperature rises - a key advantage over silicon rectifiers in high-ambient environments.
How is polarity marked on the MBRF20150CT-Y package?
Polarity on the MBRF20150CT-Y is marked on the device body per the official marking diagram: the cathode band (a white or light-colored stripe) identifies the cathode side of each diode, and the tab is the common anode. Lead 1 corresponds to Cathode 1, Lead 2 to Cathode 2, and the tab (Lead 3) is Anode 1/Anode 2. Mounting torque must not exceed 0.56 N·m to avoid internal damage.
