Product details
Overview
MBR1535CT from Taiwan Semiconductor is a 15A, 35V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.84V forward voltage at 15A/25°C, 150A surge capability, and AEC-Q101 qualification option (MBR1535CTH). It serves as a high-efficiency output rectifier in DC-DC converters and SMPS secondary-side circuits.
For engineers reviewing the MBR1535CT datasheet, MBR1535CT pinout, MBR1535CT application, or MBR1535CT equivalent, key selection criteria include its 35V VRRM rating, dual-common-cathode configuration, 1.5°C/W junction-to-case thermal resistance, and suitability for automotive-grade power conversion where low conduction loss and robust surge handling are required.
Technical Context
The MBR1535CT integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling full-wave rectification or dual-channel synchronous rectification. Its guard ring structure provides overvoltage protection, and it supports operation from –55°C to +150°C junction temperature.
With 10°C/W junction-to-ambient thermal resistance and matte tin-plated leads compliant with J-STD-002, the device delivers stable performance under sustained 15A DC load when properly heatsinked. The 10,000 V/μs critical dv/dt rating ensures reliable commutation in fast-switching topologies.
Key Specifications

| IF | 15 A - Continuous forward current per diode; supports high-current secondary-side rectification |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); withstands startup/load-dump transients |
| VF @ 15A, 25°C | 0.84 V - Low conduction loss; reduces power dissipation vs. silicon diodes in high-frequency SMPS |
| RθJC | 1.5 °C/W - Enables efficient heat transfer to heatsink; critical for thermal management in compact designs |
| IR @ 35V, 25°C | 500 µA - Low leakage per diode; preserves efficiency in standby and light-load conditions |
| TJ max | +150 °C - Extended junction temperature range supports under-hood and industrial environments |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15CTQ035 | Same 35V VRRM, 15A IF, TO-220AC package (isolated tab), VF = 0.72V @ 15A/25°C | No AEC-Q101 variant offered; lower RθJC (1.2°C/W) but non-isolated tab requires insulation | Select for higher thermal performance where isolation is managed externally |

FAQ
What is the pin configuration of the MBR1535CT?
The MBR1535CT uses a TO-220AB package with three terminals: Pin 1 (left) is Anode 1, Pin 2 (center) is the common cathode electrically tied to the metal tab, and Pin 3 (right) is Anode 2. The cathode tab must be electrically isolated from chassis unless referenced to system ground, and polarity is marked on the device body.
Does the MBR1535CT have automotive qualification?
The standard MBR1535CT is not AEC-Q101 qualified, but the MBR1535CTH variant-identical in all electrical and thermal specs-is fully AEC-Q101 certified for automotive applications. Both share the same TO-220AB package and marking format, differing only in qualification status and packing code "H".
What is the maximum junction temperature for the MBR1535CT?
The MBR1535CT has a maximum junction temperature (TJ max) of +150°C, with a storage temperature range of –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed industrial drives or under-hood automotive electronics when mounted on an appropriate heatsink.
How does the MBR1535CT compare to silicon rectifiers in efficiency?
The MBR1535CT achieves 0.84V forward voltage at 15A/25°C-significantly lower than equivalent 35V silicon rectifiers (~1.1V)-reducing conduction losses by ~31%. At 125°C, its VF drops to 0.72V, further widening the efficiency gap in thermally stressed applications like high-power adapters.
Is thermal derating required for the MBR1535CT at elevated ambient temperatures?
Yes. Due to its 10°C/W junction-to-ambient thermal resistance, the MBR1535CT must be derated above 25°C ambient. At 70°C ambient with no heatsink, its usable DC current drops to ~9.5A; with a 2°C/W heatsink, it sustains 15A up to 65°C ambient. Derating curves are provided in Figure 1 of the official datasheet.
