Product details
Overview
MBR1035CT from Taiwan Semiconductor is a dual-die, TO-220AB-packaged Schottky barrier rectifier rated for 10 A average forward current and 35 V repetitive peak reverse voltage, with 0.70 V max forward voltage at 5 A/25°C and 120 A non-repetitive surge capability - used in high-efficiency AC/DC adapters and DC/DC converters.
For engineers reviewing the MBR1035CT datasheet, MBR1035CT pinout, MBR1035CT application, or MBR1035CT equivalent, key selection criteria include its low VF at 10 A (0.80 V @ 25°C), 1.5 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (MBR1035CTH), and dual-common-cathode configuration for bridge or dual-output topologies.
Technical Context
The MBR1035CT integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling half-wave dual-output or full-wave center-tapped rectification. Its guard ring structure provides overvoltage protection, and it supports operation up to 150 °C junction temperature.
Designed for switching-mode power supplies, the device delivers high efficiency via low forward voltage drop and low reverse recovery charge (inherent to Schottky architecture), while its 10,000 V/μs critical dv/dt rating ensures robustness against fast transients in high-frequency converters.

FAQ
What is the maximum junction temperature rating for the MBR1035CT?
The MBR1035CT has a maximum junction temperature (TJ max) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version O2104. This allows uninterrupted operation in sealed enclosures or high-ambient environments, provided thermal design maintains junction temperature below this limit using the specified 1.5 °C/W RθJC value. Derating curves in Figure 1 confirm usable current down to 5 A at 100 °C case temperature.
Is the MBR1035CT pin-compatible with other parts in the MBR10xxCT series?
Yes, all MBR10xxCT variants - including MBR1035CT, MBR1045CT, and MBR10200CT - share identical TO-220AB package dimensions, pinout (anode-anode-cathode tab), and mechanical mounting specifications. However, electrical parameters differ significantly: VRRM ranges from 35 V to 200 V, and VF increases with voltage rating. Thus, direct substitution requires verification of reverse voltage margin and forward loss impact in the target circuit.
Does the MBR1035CT have AEC-Q101 qualification?
The base MBR1035CT is not AEC-Q101 qualified, but Taiwan Semiconductor offers the MBR1035CTH variant - identical electrically and mechanically - which is fully AEC-Q101 qualified per stress test requirements for automotive applications. The "H" suffix denotes qualification; ordering code and marking include "H", and packaging remains TO-220AB in 50/tube format.
What is the forward voltage specification for MBR1035CT at 10 A and 125 °C?
Per the Electrical Specifications table in the Taiwan Semiconductor datasheet (Version O2104), the MBR1035CT exhibits a maximum forward voltage (VF) of 0.67 V at 10 A and TJ = 125 °C. This low high-temperature VF reflects stable Schottky performance and supports reliable operation in thermally demanding environments such as enclosed power supplies or automotive under-hood modules.
How does the guard ring feature improve reliability in the MBR1035CT?
The guard ring in the MBR1035CT mitigates edge breakdown under transient overvoltage conditions by distributing electric field stress away from the active junction periphery. As confirmed in the datasheet's Features section, this structure enhances ruggedness during line surges or inductive switching events - reducing failure risk in unregulated input stages without requiring additional external clamping components.
