Overview
The CMPSH-3A TR PBFREE is a dual common anode silicon Schottky diode array in a SOT-23 surface mount package. It features a peak repetitive reverse voltage of 30 V and a continuous forward current of 100 mA per diode. The device exhibits a maximum forward voltage of 1.00 V at 100 mA and a typical reverse recovery time of 5.0 ns. Operating junction temperature ranges from -65°C to +150°C with a thermal resistance of 357 °C/W.
Feature Summary
- Dual common anode configuration for efficient rectification
- Low forward voltage drop for improved efficiency
- Fast switching capability with short reverse recovery time
- Surface mount design suitable for automated assembly
Applications
- DC-DC converter circuits
- Power supply rectification
- Free-wheeling diodes in inductive loads
- Clamping applications in fast switching environments
Procurement Notes
Verify the specific ordering suffix required for plating options. Use 'PBFREE' for lead-free devices or 'TIN/LEAD' for tin/lead plated versions as specified by Central Semiconductor. Confirm package type and marking codes match design requirements before finalizing orders.
Selection Notes
Select this component for applications requiring low forward voltage and fast recovery in a compact SOT-23 footprint. Ensure the 30 V reverse voltage rating exceeds circuit peak voltages. Consider the 100 mA continuous current limit and thermal dissipation constraints when designing heat management solutions.
Part Context
This part belongs to the CMPSH-3 series of surface mount silicon Schottky diodes. Other variants include single, common cathode, and series configurations within the same SOT-23 package family, offering flexibility for different circuit topologies while maintaining consistent electrical characteristics.
Replacement Considerations
Direct substitutes must match the dual common anode configuration, 30 V rating, and SOT-23 package. Verify equivalent forward voltage and reverse recovery time specifications to ensure circuit performance compatibility without redesign.
