Product details
Overview
MBRS1535CT from Taiwan Semiconductor is a 15A, 35V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.84V forward voltage at 15A/25°C, 150A surge rating, and 2°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in DC-DC converters and switching power supplies.
For engineers reviewing the MBRS1535CT datasheet, MBRS1535CT pinout, MBRS1535CT application, or MBRS1535CT equivalent, key selection criteria include its 35V VRRM, dual-common-cathode configuration, low thermal resistance, and suitability for high-current, high-frequency SMPS output stages where low conduction loss and fast recovery are critical.
Technical Context
The MBRS1535CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, enabling synchronous rectification or dual-output configurations. Its 150A IFSM rating supports robust transient handling in power supply startup and overload conditions.
Designed for operation up to 150°C junction temperature, it delivers stable forward voltage performance (0.72V max at 15A/125°C) and low reverse leakage (100µA max at 25°C, 15mA max at 125°C), making it suitable for thermally constrained industrial and adapter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse voltage; defines safe blocking capability in 12–24V output rails |
| IF | 15 A - Continuous forward current per diode; supports high-power DC-DC outputs without forced air cooling |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients |
| VF @ 15A, 25°C | 0.84 V - Low conduction loss; reduces power dissipation and improves efficiency in high-current paths |
| RθJC | 2 °C/W - Low junction-to-case thermal resistance; enables effective heat transfer to PCB copper or heatsink |
| TJ max | 150 °C - Maximum operating junction temperature; supports reliable operation in sealed or high-ambient environments |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with anode-anode-cathode arrangement. Cathode terminal is electrically connected to the exposed metal tab for enhanced thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Pin 2 (Center) | Anode of Diode 2 | Independent input node for second rectification path; enables dual-output or phase-interleaved topologies |
| Pin 3 (Right / Tab) | Common Cathode | Shared output node and thermal interface; must be soldered to large copper pour for thermal management |
Key Features

FAQ
What is the maximum junction temperature rating for the MBRS1535CT?
The MBRS1535CT has a maximum junction temperature (TJ) rating 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 power supplies or industrial enclosures. Thermal design must ensure that actual junction temperature stays below this limit using the specified RθJC = 2°C/W and appropriate PCB copper area. The MBRS1535CT remains fully functional down to –55°C for cold-storage or outdoor deployment scenarios.
Does the MBRS1535CT support common-cathode configuration?
Yes, the MBRS1535CT is internally configured as two Schottky diodes with a common cathode connection, accessible via the exposed metal tab (Pin 3). This architecture enables dual-output rectification, OR-ing, or interleaved converter designs without external wiring. The anodes are isolated on Pins 1 and 2, allowing independent input routing. This configuration is explicitly confirmed in the "Configuration: Dual dies" and pinout documentation for the MBRS1535CT.
What is the forward voltage specification of the MBRS1535CT at full rated current?
The MBRS1535CT specifies a maximum forward voltage (VF) of 0.84 V at IF = 15 A and TJ = 25°C, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. At elevated temperature (125°C), VF rises to 0.72 V max under the same current condition. These values are measured per diode, not per package, and reflect conduction loss directly impacting power stage efficiency in applications like DC-DC converters.
Is the MBRS1535CT RoHS and halogen-free compliant?
Yes, the MBRS1535CT is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the official Taiwan Semiconductor product documentation. The device uses matte tin-plated leads and UL 94V-0 compliant molding compound. Moisture sensitivity level is rated at Level 1 (J-STD-020), eliminating pre-bake requirements and supporting standard SMT reflow processes without risk of popcorning.
What packaging format is used for the MBRS1535CT?
The MBRS1535CT is supplied in tape-and-reel packaging, with 800 units per reel, as specified in the Ordering Information section of the Taiwan Semiconductor datasheet. The package type is TO-263AB (D2PAK), and the reel conforms to EIA-481 standards for automated pick-and-place assembly. No alternate packaging (e.g., tube or tray) is listed for this part number in official documentation.
