Diodes Incorporated MBR10100CS2-E1

Overview

MBR10100CS2-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-263-2 package, rated for 100 V reverse voltage and 5 A average forward current per diode leg, with 0.85 V max forward voltage at +25°C and 0.1 mA max reverse leakage at +25°C. It serves as output rectification in high-frequency switch-mode power supplies where low switching loss and low noise are critical.

For engineers reviewing the MBR10100CS2-E1 datasheet, MBR10100CS2-E1 pinout, MBR10100CS2-E1 application, or MBR10100CS2-E1 equivalent, key selection criteria include thermal resistance (2.0 °C/W junction-to-case), surge capability (100 A non-repetitive peak), and RoHS-compliant "Green" packaging with halogen/antimony-free molding compound.

Technical Context

This dual common-cathode Schottky rectifier integrates two independent 100 V, 5 A diode legs sharing a single cathode terminal. Its low VF and fast recovery enable high-efficiency rectification in DC-DC converters and AC-DC secondary-side outputs operating above 100 kHz.

The device features guard-ring protection for mechanical stress immunity and supports continuous operation up to +150°C junction temperature. Its TO-263-2 package provides 2.0 °C/W thermal resistance to case when mounted on recommended PCB copper area, enabling compact high-power density designs without external heatsinks.

Key Specifications

Pinout & Package

MBR10100CS2-E1 uses the TO-263-2 surface-mount package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features exposed copper pad for thermal conduction and meets UL 94V-0 flammability rating.

FAQ

What is the maximum allowable case temperature for continuous operation?

The MBR10100CS2-E1 supports continuous operation up to +136°C case temperature while delivering its full 5 A average forward current per diode leg. Exceeding this temperature requires linear derating per the datasheet curve, with zero current allowed at +150°C junction temperature.

Does the TO-263-2 package require solder paste stencil optimization for thermal pad reliability?

Yes-the TO-263-2's exposed thermal pad must be soldered using a 50–60% open-area stencil with 0.15 mm thickness to ensure void-free thermal interface. Recommended pad layout per Diodes' document DS36953 specifies X1=1.20 mm, Y1=3.83 mm, and Z=16.76 mm dimensions for optimal thermal transfer and mechanical adhesion.

Can MBR10100CS2-E1 replace a single 10 A Schottky in a center-tapped transformer design?

No-it contains two independent 5 A diode legs with a common cathode, not a single 10 A device. In center-tapped configurations, it functions as dual half-wave rectifiers, requiring separate transformer windings per anode. It cannot substitute for a true 10 A single-die Schottky without circuit rework.

Is the 0.1 mA IR specification measured at full 100 V or lower test voltage?

The 0.1 mA maximum reverse current is specified at rated DC blocking voltage (100 V) and +25°C case temperature, per Diodes' DS36953 Rev. 5–2, page 6. At +125°C, IR rises to 6.0 mA under the same 100 V bias, confirming strong temperature-dependent leakage behavior typical of Schottky junctions.
