MCR708AG

Overview

The Littelfuse MCR708AG is a Silicon-Controlled Rectifier (SCR) belonging to the MCR703A series. It features a rated repetitive off-state voltage of 800 V and an on-state RMS current rating of 4 A. The device utilizes a DPAK-2 (TO-252-2) surface mount package for compact integration. Key electrical characteristics include a maximum gate trigger current of 100 µA, a holding current of 5 mA, and a non-repetitive peak on-state current of 35 A. It operates within a temperature range of -40°C to +110°C.

Feature Summary

Sensitive gate architecture enabling direct interfacing with microprocessors
Glass passivated junctions ensuring durability against environmental factors
Surface mount construction compatible with lead-free reflow soldering processes

Applications

Strobe light control circuits
Fluid level sensing systems
Capacitive-discharge ignition applications

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official documentation to confirm compliance with RoHS directives and halogen-free status. Ensure that the ordering information matches the exact MCR708AG part number to avoid confusion with similar variants in the MCR703A family. Cross-reference datasheet revisions to confirm current production status and any potential engineering changes.

Selection Notes

Select this component when a high-voltage SCR is required in a small surface mount footprint. The 800 V blocking capability suits mains-connected or high-inductive loads. Verify that the 4 A RMS current rating meets the circuit's continuous load requirements and that the sensitive gate drive specifications align with the available control logic levels.

Part Context

This device is part of the MCR703A series of silicon-controlled rectifiers manufactured by Littelfuse. The series offers various voltage ratings within a standardized DPAK-2 package, providing designers with consistent mechanical dimensions while allowing flexibility in voltage selection for different power control applications.
