Overview
The CMRSH-4DO TR PBFREE is a surface mount silicon dual, isolated, opposing Schottky diode in an SOT-963 package. It features a peak repetitive reverse voltage of 40 V and an average forward current of 200 mA. The device exhibits a typical forward voltage drop of 0.35 V at 1.0 mA and a maximum reverse current of 200 nA at 30 V. Switching speed is characterized by a maximum recovery time of 5.0 ns. Power dissipation is rated at 125 mW with a thermal resistance of 800 °C/W.
Feature Summary
- Dual, isolated, opposing configuration for versatile multi-configurable circuit designs
- Extremely fast switching capability with minimal reverse recovery time
- Low forward voltage drop to enhance operational efficiency
- Compact SOT-963 surface mount package suitable for space-constrained applications
Applications
- DC-DC converters
- Voltage clamping circuits
- Protection circuits
- Battery charging circuits
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance. Confirm the tape and reel quantity matches project requirements. Ensure the SOT-963 footprint aligns with the PCB layout. Cross-reference the marking code CV for visual identification during assembly inspection.
Selection Notes
Select this component when small size and high efficiency are critical. The dual opposing structure allows for bridge rectifier configurations or push-pull topologies. Evaluate the 40 V reverse voltage rating against peak line transients. Consider the 200 mA current limit for load requirements. The low capacitance supports high-frequency operation in sensitive signal paths.
Part Context
This part belongs to Central Semiconductor's surface mount Schottky rectifier family. It utilizes the SOT-963 case outline designed for automated pick-and-place assembly. The dual isolated architecture differentiates it from standard single-diode packages. It serves as a compact solution for power management modules requiring bidirectional blocking capabilities.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
