16CTQ200

Overview

The 16CTQ200 is a dual Schottky barrier rectifier manufactured by SMC Diode Solutions, housed in a TO-220AB package. It features a common cathode configuration with two independent diodes. The device supports a maximum repetitive peak reverse voltage of 200V and an average forward rectified current of 8A per diode. Key electrical characteristics include a maximum DC forward voltage of 1.05V at 8A and a non-repetitive peak forward surge current rating of 200A. The component operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Dual common cathode Schottky rectifier design for efficient power conversion
• Low forward voltage drop minimizes power dissipation and heat generation
• High thermal stability supports operation up to 175°C junction temperature
• Robust construction handles high surge currents during transient events

Applications

• DC-DC converter circuits requiring low loss rectification
• Free-wheeling diodes in inductive load protection schemes
• Power supply output rectification stages
• Battery charging circuit protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct pinout and packaging configuration. Confirm RoHS compliance status if required for your assembly process. Cross-reference the thermal resistance parameters with your heatsinking strategy to maintain safe operating temperatures under full load conditions.

Selection Notes

Select this component when a dual common cathode topology is required for synchronous or asynchronous rectification. Ensure the 200V reverse voltage rating exceeds the peak inverse voltage in your circuit. Evaluate the thermal management requirements based on the 8A per diode current capability and the specified forward voltage drop at your expected operating current.

Part Context

This part belongs to the 16CTQ series of dual Schottky rectifiers from SMC Diode Solutions. These devices are designed for general purpose rectification in medium-power applications. The TO-220AB package provides robust mechanical mounting and effective heat dissipation compared to surface-mount alternatives.

Replacement Considerations

Direct substitutes must match the dual common cathode Schottky configuration, 200V reverse voltage, and 8A current rating. Verify that alternative packages offer equivalent thermal performance and pin compatibility.
