TYN30-800TQ

Scrs Overview

The TYN30-800TQ is a planar passivated Silicon Controlled Rectifier (SCR) manufactured by WeEn Semiconductors. It features an RMS on-state current of 30 A and a non-repetitive peak on-state current of 350 A. The device supports a rated repetitive peak off-state voltage of 800 V with a maximum off-state leakage current of 200 uA at VDRM. Gate triggering parameters include a maximum gate trigger voltage of 700 mV and a maximum gate trigger current of 4.5 mA. It operates within a junction temperature range up to +150 °C and utilizes a TO-220 through-hole package.

Scrs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging configuration, as standard part numbers may correspond to different packing methods such as rail packs or tubes. Confirm RoHS compliance status and REACH SVHC declarations via the latest datasheet before procurement. Cross-reference the 12NC code 9340 721 51127 with supplier catalogs to match exact physical specifications and avoid substitution errors during component sourcing.

Scrs Selection Notes

Select this component when designs require robust surge handling alongside moderate continuous current ratings in a through-hole format. The 800 V blocking voltage provides adequate margin for standard industrial AC line voltages. Ensure the driving circuit can supply the specified gate trigger current while accounting for temperature variations that affect holding current thresholds. Verify PCB layout accommodates the thermal dissipation requirements inherent to the TO-220 package geometry.

Scrs Part Context

This SCR belongs to the TYN series of planar passivated devices designed for industrial environments. It shares architectural similarities with other high-current thyristors but distinguishes itself through its specific 30 A RMS rating and 800 V voltage class. The TO-220 package facilitates direct mounting to heatsinks, supporting the device's capability to manage significant power dissipation during operation.
