TYN50Y-800TQ

Scrs Overview

The TYN50Y-800TQ is a silicon controlled rectifier (SCR) manufactured by WeEn Semiconductors, designed for high blocking voltage applications. It features an RMS on-state current of 50 A and a non-repetitive peak on-state current of 430 A. The device supports a rated repetitive off-state voltage of 800 V with a maximum off-state leakage current of 200 uA at VDRM. Key gate parameters include a trigger voltage of 1.2 V and a trigger current of 40 mA. Operating within a temperature range of -40 C to +150 C, it utilizes a TO-220AB-3 package for through-hole mounting.

Scrs Feature Summary

• Planar passivated construction ensures high blocking voltage capability and robust performance in demanding environments.
• High commutation characteristics provide improved immunity to false turn-on caused by rapid voltage changes.
• Designed for efficient interfacing with microcontrollers, logic integrated circuits, and low power gate drive circuits.

Scrs Applications

• Industrial motor control systems requiring high current handling
• Solid-state relay designs for AC load switching
• Phase control circuits for power regulation

Scrs Procurement Notes

Verify the specific suffix 'TQ' against the manufacturer's official datasheet to confirm packaging configuration and marking standards. Ensure that the procurement channel provides valid traceability documentation compliant with RoHS and REACH regulations. Cross-reference the part number with the latest product change notifications to confirm component availability and manufacturing status before finalizing orders.

Scrs Selection Notes

Select this component when circuit requirements demand a 50 A RMS current rating combined with an 800 V blocking voltage. The TO-220AB-3 through-hole package facilitates straightforward thermal management and mechanical mounting in industrial enclosures. Consider the 150 C maximum junction temperature for high-temperature operational environments where standard silicon limits may be exceeded.

Scrs Part Context

This SCR belongs to the TYN series of planar passivated thyristors from WeEn Semiconductors. The series is engineered for general-purpose power switching applications, offering a balance of high current capacity and reliable gate triggering. The TYN50Y-800TQ variant specifically targets applications needing robust AC control with standardized pin configurations for easy integration into existing board layouts.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative SCRs based on matching electrical ratings, package dimensions, and thermal characteristics rather than direct cross-referencing.
