Overview
The 12CTQ045S is a Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common cathode configuration housed in a TO-263AB (D2PAK) surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 45V and an average forward rectified current of 12A per diode. Key electrical characteristics include a low forward voltage drop and fast switching speeds, with a typical reverse recovery time of less than 500ns at specified conditions. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Dual common cathode configuration for efficient bridge or full-wave rectification applications
- Low forward voltage drop characteristic for improved power efficiency
- Fast switching capability suitable for high-frequency operation
- Robust thermal performance via exposed pad mounting
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in inductive load circuits
- Power supply input rectification stages
- Battery charging circuit protection
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout orientation and packaging variations. Confirm availability status as product lines may undergo lifecycle changes. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when a dual common cathode topology is required for synchronous or asynchronous rectification. Compare the 12A current rating against the peak load requirements of the circuit. Evaluate the TO-263AB package for adequate PCB copper area to support the 12A continuous current and thermal dissipation needs.
Part Context
This part belongs to Vishay's CT series of Schottky rectifiers designed for general-purpose power conversion. The series offers various current ratings and voltage options in standardized surface-mount packages. The 12CTQ045S specifically addresses mid-power applications requiring reliable rectification with low loss characteristics.
Replacement Considerations
Consult official cross-reference lists for direct replacements such as the 12TQ045 or equivalent parts from other manufacturers offering identical TO-263AB dual common cathode configurations with matching 45V/12A ratings.
