Overview
The Vishay 12TQ040 is a single Schottky rectifier with a maximum DC reverse voltage of 40 V and an average forward current rating of 15 A. It utilizes TO-220AC packaging for through-hole mounting. The device operates reliably up to a junction temperature of 150 °C, featuring a typical forward voltage drop of 0.50 V at 15 A and 125 °C. Maximum non-repetitive surge current reaches 990 A under specified pulse conditions.
Feature Summary
- Optimized proprietary barrier technology ensures very low forward voltage drop while maintaining moderate leakage characteristics.
- High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance.
- Guard ring design enhances ruggedness and long-term reliability for industrial level applications.
Applications
- Switching power supplies
- Converters
- Freewheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix when purchasing. Standard production units lack a suffix, whereas PbF variants indicate lead-free compliance. Confirm package style matches requirements, as standard packing quantities are typically 50 pieces per tube. Ensure technical specifications align with the target application constraints before procurement.
Selection Notes
Select this component for circuits requiring robust thermal performance up to 150 °C junction temperature. The TO-220AC package facilitates effective heat dissipation for 15 A continuous operation. Consider the 0.50 V forward voltage drop at elevated temperatures to minimize conduction losses in high-efficiency designs.
Part Context
This part belongs to the 12TQ... Schottky rectifier series from Vishay High Power Products. The series includes variants rated for 35 V, 40 V, and 45 V reverse voltages, all sharing the same 15 A current rating and physical package dimensions. The 12TQ040 specifically addresses the 40 V requirement within this lineup.
Replacement Considerations
