Overview
The 12TQ040 is a single Schottky rectifier diode manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current rating of 15 A at case temperature. The device utilizes a TO-220AC through-hole package for mounting. It is designed as a lead-free component, with all parts traceable to the wafer lot.
Feature Summary
- Schottky barrier technology for low voltage drop
- Super-high speed switching capability
- Low noise operation characteristics
Applications
- General purpose rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Reverse polarity protection circuits
Procurement Notes
Verify the specific datasheet revision before ordering, as manufacturers may update specifications. Confirm that the required package type matches the TO-220AC form factor. Ensure the application environment supports the thermal requirements associated with the 15 A current rating. Check for any specific lead-free compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a 40 V reverse voltage rating and 15 A continuous current capacity are required. The TO-220AC package provides robust mechanical stability for through-hole assembly. Consider the low forward voltage drop benefits for efficiency in low-voltage applications. Verify that the switching speed meets the frequency requirements of the target circuit design.
Part Context
This part belongs to the TQ series of Schottky rectifiers from SMC Diode Solutions. The series offers various voltage and current combinations. The 12TQ040 specifically targets applications needing moderate voltage blocking with high current handling. It complements other variants like the 10TQ040 or 12CTQ040 in different package or dual-diode configurations.
Replacement Considerations
Direct substitutes include the 12TQ040S variant. Other compatible options within the same family may include different suffixes indicating packaging changes. Verify pinout compatibility and thermal resistance values when substituting with similar Schottky diodes from other manufacturers.
