12CTQ030

Overview

The 12CTQ030 is a Schottky rectifier diode array manufactured by SMC Diode Solutions. It features a common cathode configuration housed in a TO-220AB through-hole package. The device supports a maximum repetitive peak reverse voltage of 30V and an average rectified current of 6A per diode, totaling 12A for the pair. Key electrical characteristics include a maximum DC forward voltage of 580mV at 6A and a maximum reverse leakage current of 100µA at 30V. The component operates within a junction temperature range of -65°C to 175°C and maintains a thermal resistance from junction to case of 1.0°C/W.

Feature Summary

• Schottky barrier technology ensures low forward voltage drop and high switching efficiency
• Common cathode dual configuration simplifies circuit design for parallel applications
• Robust TO-220AB leaded package provides reliable thermal dissipation for through-hole mounting

Applications

• High-frequency power supply rectification
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits in electronic systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pinout and packaging variations. Ensure that the requested components match the specified TO-220AB form factor and electrical ratings required for the target application environment. Cross-reference part numbers with authorized distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this component when low forward voltage loss and fast recovery times are critical for system efficiency. The 30V rating suits low-voltage DC bus applications, while the 6A per-diode capacity handles moderate load currents. Consider the thermal resistance and package size constraints during PCB layout to ensure adequate heat sinking and mechanical stability under continuous operation conditions.

Part Context

This part belongs to the series of Schottky rectifier arrays designed for general-purpose power conversion tasks. It complements other devices in the product line offering similar current and voltage specifications but with different package options or configurations. The common cathode arrangement allows for efficient implementation in bridge-like topologies without requiring discrete diode matching.

Replacement Considerations

Consult the manufacturer's substitution guide for direct equivalents with identical electrical parameters and pin compatibility. Verify that any alternative parts maintain the same 30V reverse voltage and 6A current ratings to prevent performance degradation or failure in existing designs.
