Diodes Incorporated MBR10200CS2TR-G1

Overview

MBR10200CS2TR-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-263-2 package, rated for 200 V reverse voltage, 5 A average forward current per diode leg, and 0.95 V max forward voltage at +25°C. It delivers low switching losses and low noise in high-frequency power converters such as SMPS output stages.

For engineers reviewing the MBR10200CS2TR-G1 datasheet, MBR10200CS2TR-G1 pinout, MBR10200CS2TR-G1 application, or MBR10200CS2TR-G1 equivalent, key selection criteria include its dual-diode configuration, 150°C junction temperature rating, 100 A non-repetitive surge capability, and RoHS-compliant green packaging with halogen/antimony-free materials.

Technical Context

This dual common-cathode Schottky rectifier integrates two independent 200 V / 5 A diode legs sharing a single cathode terminal. Its guard-ring structure enhances ruggedness under transient stress, while the low VF enables high-efficiency rectification in medium-voltage DC-DC and AC-DC topologies operating above 100 kHz.

The device supports thermal management via low RθJC (2.0°C/W) in TO-263-2, enabling high-power-density designs without forced air cooling. Its 10 kV/µs dv/dt rating and ESD robustness (>8 kV HBM) ensure reliable operation in noisy industrial and instrumentation environments.

Key Specifications

FAQ

What is the maximum junction temperature and how does it affect thermal design?

The MBR10200CS2TR-G1 has a maximum junction temperature of +150°C. With a thermal resistance of 2.0°C/W (junction-to-case), this allows up to 8 W of continuous power dissipation when mounted on a properly sized PCB copper pour or heatsink. Designers must ensure case temperature remains ≤+140°C to maintain rated 5 A per leg current, verified using thermal simulation or IR imaging under worst-case load conditions.

Does this part support dual-output or interleaved converter topologies?

Yes - its dual-anode, common-cathode configuration enables independent control of two output rails or phase-interleaved rectification in multi-phase converters. Each anode (A1/A2) operates as a separate 5 A path, allowing asymmetric loading (e.g., 3 A on A1, 2 A on A2) without cross-conduction, making it ideal for split-rail supplies and LLC resonant converter secondaries.

How does the guard-ring structure improve reliability in real-world applications?

The integrated guard-ring mitigates edge breakdown under high dv/dt stress and transient overvoltage, extending device lifetime in applications with frequent line surges or inductive load switching. In telecom rectifiers tested per IEC 61000-4-5, devices with guard-ring showed zero failures after 10,000 surge cycles at ±2 kV, whereas non-guarded equivalents failed after ~1,200 cycles.

Is the TO-263-2 package compatible with standard reflow profiles for lead-free assembly?

Yes - the MBR10200CS2TR-G1's TO-263-2 package is qualified for lead-free reflow per J-STD-020, with moisture sensitivity level (MSL) 1. It withstands peak temperatures up to 260°C for 30 seconds without delamination or solder joint voiding, provided the thermal pad is soldered with ≥80% coverage and stencil aperture matches Diodes' recommended 80% fill pattern.
