Product details
Overview
MBRS2535CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 35 V repetitive peak reverse voltage, and 200 A non-repetitive surge current; it delivers low forward voltage (0.65 V typ. at 12.5 A, 25°C) and operates up to 150°C junction temperature, ideal for automotive DC/DC converters requiring high efficiency and AEC-Q101 qualification.
For engineers reviewing the MBRS2535CTH datasheet, MBRS2535CTH pinout, MBRS2535CTH application, or MBRS2535CTH equivalent, key selection criteria include its 35 V VRRM, dual-common-cathode configuration, 1.0 °C/W junction-to-case thermal resistance, AEC-Q101 qualification, and suitability for reverse battery protection and freewheeling in 12 V automotive systems.
Technical Context
The MBRS2535CTH integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, enabling synchronous rectification or dual-path freewheeling. Its guard ring structure provides overvoltage protection, and the device supports high-frequency switching with 10,000 V/μs critical rate of rise of off-state voltage.
Designed for automotive-grade reliability, it meets JESD201 Class 2 whisker resistance and J-STD-020 moisture sensitivity level 1. Thermal performance is characterized by RθJC = 1.0 °C/W, allowing efficient heat transfer to the PCB copper plane under 25 A continuous conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per diode; defines safe operation in 12 V automotive bus applications with transient margin. |
| IF | 25 A - Average forward current per diode at TC = 110°C; enables compact DC/DC converter designs without forced air cooling. |
| IFSM | 200 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands load dump and cranking transients in vehicle power systems. |
| VF | 0.65 V (typ.) at 12.5 A, 25°C - Low conduction loss improves system efficiency and reduces thermal stress in high-current paths. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables direct thermal coupling to heatsinked PCB copper for stable 150°C operation. |
| TJ max | +150°C - Maximum junction temperature; supports under-hood deployment in automotive engine control modules. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with anode–anode–cathode pinout and exposed thermal pad (pin 3 = cathode, pins 1 & 2 = anodes).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Connects to input/high-side switching node; electrically isolated from Pin 2 but shares cathode path. |
| Pin 2 | Anode of Diode 2 | Enables dual-input or phase-split freewheeling; identical electrical characteristics to Pin 1. |
| Pin 3 | Common Cathode | Thermally enhanced metal tab; must be soldered to large copper pour for thermal management and current return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use across temperature, humidity, and mechanical shock profiles per JEDEC standard. |
| Guard ring overvoltage protection | Enhances ruggedness against voltage transients without external snubbers in 12 V battery systems. |
| Moisture sensitivity level 1 | Zero bake requirement before reflow; compatible with standard SMT assembly lines without dry-pack handling. |

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-MBR2535CT | Same 35 V VRRM, 25 A IF, TO-263AB package; VF = 0.67 V max at 12.5 A, 25°C - slightly higher typical forward drop. | Not AEC-Q101 qualified; intended for industrial/commercial use only. | Select when automotive qualification is not required and cost optimization is prioritized. |
| ON Semiconductor MBR2535CT | Identical ratings and TO-263AB footprint; VF = 0.66 V max at 12.5 A, 25°C; RθJC = 1.2 °C/W - 20% higher thermal resistance. | Qualified to AEC-Q101 Rev D; same automotive use case eligibility but reduced thermal margin at full load. | Select when board-level thermal design accommodates higher junction rise or when second-source validation is mandated. |
Compared with VS-MBR2535CT and MBR2535CT, the MBRS2535CTH offers the lowest thermal resistance (1.0 °C/W), AEC-Q101 qualification, and tightest forward voltage distribution - making it optimal for thermally constrained, safety-critical automotive power stages where long-term reliability under transient stress is essential.

FAQ
What is the pin configuration of the MBRS2535CTH?
The MBRS2535CTH uses a 3-pin TO-263AB (D2PAK) package with pins 1 and 2 as independent anodes and pin 3 as the common cathode. The exposed metal tab (pin 3) serves as both the cathode electrical connection and primary thermal path to the PCB. This dual-anode/common-cathode layout supports parallel or OR-ing configurations without external wiring.
Is the MBRS2535CTH suitable for automotive applications?
Yes, the MBRS2535CTH is AEC-Q101 qualified and designed for automotive use. It operates from −55°C to +150°C, meets JESD201 Class 2 whisker resistance, and has moisture sensitivity level 1 - eliminating bake requirements before reflow. Its 200 A surge rating and guard ring structure make it appropriate for under-hood DC/DC converters and reverse battery protection in vehicles.
What is the maximum forward voltage drop for the MBRS2535CTH at full rated current?
At 25 A and 25°C junction temperature, the MBRS2535CTH exhibits a maximum forward voltage of 0.82 V per diode. At elevated temperature (125°C), this increases to 0.73 V - confirming stable low-loss performance across automotive operating ranges. These values are measured under pulsed conditions with 0.3 ms pulse width and 1% duty cycle.
Does the MBRS2535CTH require special PCB layout considerations?
Yes - the exposed cathode tab (pin 3) must be soldered to a minimum 200 mm² copper area with ≥4 thermal vias (0.3 mm diameter) to achieve the specified 1.0 °C/W RθJC. Insufficient copper or via count will degrade thermal performance and limit sustained current capability below 25 A. The datasheet provides recommended pad dimensions and solder stencil guidelines.
How does the MBRS2535CTH compare to higher-voltage variants like MBRS25100CTH?
The MBRS2535CTH shares the same TO-263AB package, dual-die construction, and thermal specs as MBRS25100CTH, but is optimized for 35 V blocking - resulting in lower forward voltage (0.65 V vs. 0.92 V at 12.5 A, 25°C) and higher surge current density. Use MBRS2535CTH where system voltage is ≤16 V; select higher-voltage variants only when transient immunity beyond 35 V is required.
