Product details
Overview
MBRS20150CT-Y from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 150V repetitive peak reverse voltage (VRRM), 0.99V max forward voltage at 10A/25°C, and 150A surge current capability-designed for high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the MBRS20150CT-Y datasheet, MBRS20150CT-Y pinout, MBRS20150CT-Y application, or MBRS20150CT-Y equivalent, key selection criteria include VRRM=150V, IF=20A continuous, RθJC=2°C/W thermal resistance, low VF at elevated temperature, and moisture sensitivity level 1 compliance for automated SMT assembly.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 20A diodes in a single TO-263AB thermally optimized package. Its 150V VRRM rating targets mid-voltage DC/DC stages where higher blocking voltage than 45–100V variants is required without switching to slower PN junction devices.
The device delivers 0.87V typical forward voltage at 10A and 125°C, enabling stable operation under high ambient conditions. Reverse leakage remains ≤5mA at 125°C and rated VR, supporting reliable performance in thermally constrained power supplies.
Key Specifications

|---|---|
| VRRM | 150 V - Maximum non-repetitive reverse voltage the device blocks reliably in circuit |
| IF | 20 A - Continuous average forward current per diode, defining steady-state power handling |
| IFSM | 150 A - Peak non-repetitive surge current tolerance for line transients or startup events |
| VF (10A, 25°C) | 0.99 V max - Low conduction loss critical for efficiency in high-current, low-voltage outputs |
| RθJC | 2.0 °C/W - Thermal resistance from junction to case, enabling direct heatsink mounting for thermal management |
| TJ max | +150 °C - Maximum allowable junction temperature, supporting operation in sealed or high-ambient environments |
| MSL | Level 1 - No floor life limitation or bake requirement before reflow, simplifying SMT production |
Pinout & Package

FAQ
What is the maximum junction temperature rating for MBRS20150CT-Y?
The MBRS20150CT-Y has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows sustained operation in high-ambient environments such as enclosed server power supplies or industrial control cabinets where airflow is limited. Derating curves confirm usable current capacity down to 10A at 125°C case temperature.
Does MBRS20150CT-Y support lead-free reflow soldering?
Yes, MBRS20150CT-Y supports lead-free reflow soldering. Its matte tin-plated leads comply with J-STD-002 for solderability, and the device is qualified for peak reflow temperatures up to 260°C. With Moisture Sensitivity Level 1, no pre-bake is required prior to assembly-enabling direct placement into standard Pb-free reflow profiles used in high-volume SMT lines.
What is the pin configuration of MBRS20150CT-Y in TO-263AB package?
The MBRS20150CT-Y uses a three-terminal TO-263AB (D2PAK) configuration: Pin 1 is Anode 1, Pin 2 is the common Cathode (electrically tied to the exposed metal tab), and Pin 3 is Anode 2. The tab must be soldered to a large copper pour for thermal and electrical performance. Polarity is marked on the device body per datasheet marking diagram.
How does the forward voltage of MBRS20150CT-Y vary with temperature?
MBRS20150CT-Y exhibits negative temperature coefficient for forward voltage: VF drops from 0.99V max at 10A/25°C to 0.87V max at 10A/125°C. This behavior improves conduction efficiency at elevated operating temperatures, reducing thermal runaway risk in high-power density designs. The datasheet provides full forward characteristic curves across –55°C to +150°C.
Is MBRS20150CT-Y RoHS and halogen-free compliant?
Yes, MBRS20150CT-Y is RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor certifies full compliance with EU RoHS Directive 2011/65/EU and restricts brominated flame retardants, chlorine, fluorine, iodine, and bromine to <900 ppm total halogens. Compliance documentation is available upon request from Aetrix Electronics.
