TYN612MRG

Scrs Overview

The TYN612MRG is a standard recovery silicon controlled rectifier (SCR) manufactured by STMicroelectronics. It features a 600 V repetitive peak off-state voltage and an on-state RMS current rating of 12 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220 through-hole package. Key electrical characteristics include a maximum gate trigger voltage of 1.3 V, a maximum gate trigger current of 5 mA, and a maximum on-state voltage of 1.6 V. The holding current is specified at a maximum of 20 mA, with a non-repetitive surge current capability of 120 A at 50 Hz.

Scrs Procurement Notes

Verify the specific suffix MRG against the manufacturer's datasheet to confirm pinout configuration and packaging details. Ensure the selected component matches the required 600V blocking voltage and 12A RMS current ratings for the target application. Confirm RoHS compliance status and check for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement.

Scrs Selection Notes

Select this component when a standard SCR with 600V blocking capability and 12A continuous current handling is required. Consider the TO-220 package for adequate thermal dissipation in through-hole designs. Evaluate the 5mA gate trigger current requirement against the driving circuit capabilities. Compare against other TYN612 variants if higher voltage ratings or surface-mount options are needed for the specific system constraints.

Scrs Part Context

The TYN612MRG belongs to the TYN612 series of standard SCRs from STMicroelectronics. This family provides optimized performance in limited spaces and supports various modes of control. The series includes variants with different voltage ratings and packages, offering flexibility for diverse industrial and consumer electronics applications requiring reliable AC switching.

Scrs Replacement Considerations

Check for direct substitutes within the TYN612 series, such as TYN612RG, noting potential differences in gate trigger current specifications.
