Procurement Notes

Purchasers are advised to contact the SMC Diode Solutions sales department directly before ordering to obtain the latest version of the datasheet(s). Verify that the specific part number variant matches the required package type, as suffixes may indicate different physical configurations or packaging options. Ensure compatibility with thermal management requirements given the 175°C junction temperature rating.

Selection Notes

Select the 12TQ150 when a through-hole Schottky rectifier with 15A continuous current handling and 150V blocking voltage is required. The TO-220AC package facilitates easy mounting on heat sinks for thermal dissipation. Consider this component for applications prioritizing low forward voltage drop and high reliability under elevated temperature conditions compared to standard silicon rectifiers.

Part Context

This component belongs to the 12T series of Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining consistent current handling capabilities. The 12TQ150 specifically addresses mid-voltage, high-current applications requiring robust performance in compact through-hole designs.

Replacement Considerations

Verify pinout compatibility and thermal resistance values when substituting. Check if alternative manufacturers offer equivalent TO-220AC packaged Schottky diodes with matching 15A/150V ratings and similar forward voltage characteristics.
