WN3S3045CQ

Diode Arrays Overview

The WeEn Semiconductors WN3S3045CQ is a dual common cathode power Schottky rectifier designed for high-frequency switched mode power supplies. It utilizes a TO-263 plastic package and features industrial qualification. Key electrical parameters include a maximum repetitive reverse voltage (VRRM) of 45 V, an average forward current (IF(AV)) of 15 A, and a maximum forward voltage (VF) of 0.48 V at rated conditions. The device supports a surge forward current (IFSM) of 150 A and operates with a maximum junction temperature (Tj) of 150°C.

Diode Arrays Feature Summary

• Dual common cathode configuration optimized for center-tap applications
• Very small conduction losses due to low forward voltage characteristics
• Negligible switching losses suitable for high-frequency operation
• Industrial grade qualification ensuring robust performance

Diode Arrays Applications

• Switch mode power supplies (SMPS)
• High frequency DC to DC converters
• Low voltage high frequency inverters
• Free wheeling diode circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific suffix 'CQ' against official manufacturer documentation to confirm exact packaging or tape-and-reel specifications, as standard listings often reference 'CB'. Ensure the component meets industrial qualification requirements for your target application environment. Cross-reference the 12NC code 9340 733 83118 for accurate ordering details.

Diode Arrays Selection Notes

Select this component when designing circuits requiring low forward voltage drop and fast switching speeds in a compact surface-mount package. The 45 V rating and 15 A current capacity make it suitable for low-voltage, high-current outputs. Consider thermal management solutions given the 150°C maximum junction temperature limit and the power dissipation inherent in high-frequency switching environments.

Diode Arrays Part Context

This device belongs to the Schottky Rectifier category within the WeEn Semiconductors portfolio. It complements other silicon power diodes such as standard and fast recovery types. The product line emphasizes planar passivation technology for high-voltage durability and dynamic performance, targeting efficient power conversion in consumer and industrial electronics.

Diode Arrays Replacement Considerations

The STPS3045C is a comparable dual center-tap Schottky rectifier offering similar 45 V and 30 A ratings, though packaged in TO-220AB, TO-247, or D²PAK rather than TO-263. Verify pinout compatibility and thermal resistance differences before substitution.
