MCR718T4

Overview

The MCR718T4 is a reverse blocking thyristor (SCR) in the MCR716/MCR718 series, manufactured by onsemi. It features a DPAK surface mount package (Case 369C). The device has a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 4.0 A at a case temperature of 90°C. The average on-state current is 2.6 A under the same thermal conditions. Peak non-repetitive surge current capability is 25 A for a half-cycle sine wave at 60 Hz. Operating junction temperature ranges from -40 to +110 °C.

Feature Summary

Passivated die construction ensures reliability and uniformity
Low level triggering and holding characteristics facilitate efficient gate drive
Surface mount lead form allows for automated assembly processes
Epoxy formulation meets UL 94 V-0 flammability standards

Applications

Motor control circuits
Process control systems
Temperature regulation applications
Light control dimmers
Speed control mechanisms

Procurement Notes

Verify the specific ordering suffix 'T4' corresponds to tape and reel packaging containing 2500 units per reel as documented in the manufacturer's ordering information. Confirm that the component designation matches the preferred device status within the MCR716/MCR718 family. Ensure compatibility with the specified Case 369C footprint dimensions during procurement planning.

Selection Notes

Select this component when a 600 V blocking voltage is required for high-volume industrial or consumer applications. The DPAK package offers a compact solution for surface mount designs. Consider the 4.0 A RMS current rating against the expected load requirements. Evaluate the low gate trigger current specifications to ensure compatibility with available drive circuitry.

Part Context

This part belongs to the MCR716/MCR718 series of sensitive gate silicon controlled rectifiers designed for cost-effective industrial use. The series includes variants with different voltage ratings, specifically 400 V and 600 V options. These devices are engineered for robust performance in demanding environments while maintaining small physical footprints suitable for modern electronics manufacturing.
