Diodes Incorporated MBR1035CT

Overview

MBR1035CT from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 35V peak repetitive reverse voltage, with maximum forward voltage drop of 0.65V at 5A and 25°C, leakage current ≤0.1mA at rated DC blocking voltage, and thermal resistance of 3K/W junction-to-case - used for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.

For engineers reviewing the MBR1035CT datasheet, MBR1035CT pinout, MBR1035CT application, or MBR1035CT equivalent, this page delivers verified electrical parameters, validated TO-220AB terminal mapping, real-world use cases in industrial power conversion, and direct alternative comparisons based on Diodes Incorporated's DS30027 Rev. 8-2 specification document.

Technical Context

This dual-element Schottky rectifier integrates two independent anode terminals sharing a common cathode connection, enabling synchronous half-wave rectification or bidirectional clamping in compact layouts. Its guard ring die construction enhances transient immunity, while low VF and fast recovery support high-efficiency switching in 50/60Hz and higher-frequency DC-DC stages.

Rated for continuous 5A per leg (10A total), it operates across –55°C to +150°C with 100A non-repetitive surge capability and 150pF typical junction capacitance at 1MHz/4V - optimized for low-loss conduction and minimal reverse recovery loss in inductive load applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Compared with MBR1035CT, MBR1040CT offers 5V higher reverse blocking with no trade-off in conduction loss or thermal resistance, while SB1030-TB sacrifices voltage margin and surge capacity for lower VF and isolated mounting - making MBR1035CT the optimal balance for 24–32V industrial power interfaces.

FAQ

What is the maximum junction temperature for MBR1035CT?

The MBR1035CT has an operating junction temperature range of –55°C to +150°C, verified per AEC-Q101 stress testing. At 150°C case temperature, derated forward current drops to approximately 3.2A per leg, as shown in Figure 1 of DS30027 Rev. 8-2. Thermal design must maintain TJ ≤ 150°C under worst-case ambient and power dissipation conditions.

Is MBR1035CT RoHS and halogen-free compliant?

Yes. MBR1035CT carries a lead-free finish and meets EU RoHS Directive 2011/65/EU, with bromine and chlorine content each below 900ppm and antimony below 1000ppm - certified as "Green" per Diodes Incorporated's internal specifications and documented in DS30027 footnote 3.

Can MBR1035CT replace MBR1040CT in existing designs?

MBR1035CT is not a drop-in replacement for MBR1040CT due to its lower 35V VRRM versus 40V. In 24V systems with ≤15% overvoltage margin, substitution may be acceptable after verifying transient peaks remain below 35V; however, Diodes recommends retaining MBR1040CT where 40V rating is specified in the original design.

What is the thermal resistance from junction to ambient for MBR1035CT?

Diodes does not specify RθJA for MBR1035CT in DS30027. The datasheet provides only RθJC = 3K/W (junction-to-case). RθJA depends entirely on PCB layout, copper area, and heatsink interface - typical values range from 25K/W (no heatsink, minimal pad) to 8K/W (with 45mm × 20mm × 12mm heatsink per Note 5).
