Product details
Overview
MBR2035PT from Taiwan Semiconductor is a 20A, 35V Schottky barrier rectifier in TO-247AD package, featuring dual-die construction, 150A surge capability, and 1°C/W junction-to-case thermal resistance. It delivers low forward voltage (0.84V at 20A/25°C) for high-efficiency power conversion in SMPS and DC-DC converters.
For engineers reviewing the MBR2035PT datasheet, MBR2035PT pinout, MBR2035PT application, or MBR2035PT equivalent, key selection criteria include its 35V VRRM rating, AEC-Q101 qualification option (H-suffix), TO-247AD mechanical footprint, and thermal performance under continuous 20A conduction.
Technical Context
This device operates as a unidirectional power rectifier with two independent Schottky diode dies in a single TO-247AD package. Its 35V repetitive peak reverse voltage and 150A non-repetitive surge current support robust operation in high-current switching topologies.
The MBR2035PT exhibits low forward voltage drop (0.72V at 20A/125°C) and low reverse leakage (100µA at 25°C, 15mA at 125°C), enabling efficient thermal management in compact power supplies where junction temperature must stay ≤150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IF | 20 A - Continuous forward current rating; determines heatsink sizing for steady-state conduction loss |
| IFSM | 150 A - Peak non-repetitive surge current; supports inrush and transient overload without failure |
| VF @ 20A/25°C | 0.84 V - Forward voltage drop; directly impacts conduction loss (P = IF × VF) and thermal design |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; enables precise case temperature estimation from power dissipation |
| TJ max | 150 °C - Maximum allowable junction temperature; sets upper boundary for thermal margin in sealed enclosures |
| IR @ 25°C | 100 µA - Reverse leakage current; critical for low-power standby modes and high-impedance bias networks |
Pinout & Package

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-20CPQ035 | Same 20A/35V rating, TO-247AC package (non-isolated tab), RθJC = 1.2°C/W | Lacks AEC-Q101 option and guard ring; lower surge rating (120A) | Preferred for cost-sensitive industrial designs where isolation and automotive qualification are not required |
| ON Semiconductor MBR2035CT | 20A/35V, TO-220AB package, single-die, RθJC = 2.5°C/W | Lower thermal performance; not rated for >10A continuous without significant heatsinking | Suitable for lower-power (<100W) or space-constrained designs where TO-247 mounting is impractical |
Compared with VS-20CPQ035 and MBR2035CT, the MBR2035PT offers superior thermal resistance (1°C/W), AEC-Q101 qualification path, and integrated guard ring-making it optimal for high-reliability, high-current, and thermally constrained applications where TO-247AD mounting is feasible.

FAQ
What is the maximum junction temperature rating for the MBR2035PT?
The MBR2035PT has a maximum junction temperature (TJ max) of 150°C, as specified in its absolute maximum ratings table. This rating applies under continuous operation with proper heatsinking and must be verified using actual power dissipation and measured case temperature. Exceeding 150°C risks permanent degradation of the Schottky junction and reduced reliability. Thermal design must account for RθJC = 1°C/W and ambient conditions to ensure the MBR2035PT remains within this limit during worst-case load conditions.
Does the MBR2035PT have AEC-Q101 qualification?
The base MBR2035PT is not AEC-Q101 qualified; however, the variant MBR2035PTH is explicitly listed as AEC-Q101 qualified in the ordering information section. The "H" suffix denotes automotive-grade screening and testing per AEC-Q101 standards. For automotive applications requiring qualification, MBR2035PTH-not MBR2035PT-must be selected and sourced accordingly.
What is the forward voltage drop of the MBR2035PT at full rated current?
The MBR2035PT has a maximum forward voltage (VF) of 0.84 V at 20 A and 25°C junction temperature, as specified in the electrical characteristics table. At elevated temperature (125°C), VF rises to 0.72 V under the same 20 A condition. These values are measured per diode in the dual-die configuration and reflect typical conduction loss behavior used for thermal and efficiency calculations in power supply design.
How is the pinout configured for the dual-die structure of the MBR2035PT?
The MBR2035PT uses a three-terminal TO-247AD package with Anode 1, Cathode (common), and Anode 2. The cathode is internally shared between both Schottky dies, while the anodes are electrically isolated. This configuration allows independent anode routing for applications such as dual-phase rectification or redundancy. Polarity is marked on the device body, and the metal tab is electrically isolated from all terminals.
What packaging and quantity options are available for the MBR2035PT?
The MBR2035PT is supplied in TO-247AD (TO-3P) package, packed 30 units per tube. The standard ordering code is MBR2035PT; the AEC-Q101 qualified version uses MBR2035PTH with identical packaging. No tape-and-reel or bulk options are indicated in the official documentation-only tube packaging is supported per the manufacturer's ordering information.
