MCR100-004

Overview

The MCR100-004 is a reverse blocking thyristor from the MCR100 series, designed for high-volume line-powered consumer applications. It features a sensitive gate structure allowing triggering by microcontrollers and logic circuits. The device operates with a peak repetitive off-state voltage of 200 V and supports an on-state RMS current rating of 0.8 A at 80°C. It provides a high surge current capability of 10 A and includes specified minimum and maximum values for gate trigger current (IGT), gate trigger voltage (VGT), and holding current (IH) to facilitate design. The component is housed in a plastic TO-92 package.

Feature Summary

• Sensitive gate architecture enables direct triggering by low-power microcontrollers and logic circuits
• Glass-passivated surface construction ensures reliability and uniformity across operating conditions
• Specified ranges for gate trigger current, gate trigger voltage, and holding current simplify circuit design

Applications

• Relay drivers
• Lamp drivers
• Small motor controls
• Gate drivers for larger thyristors
• Sensing and detection circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and lead-free status. The standard MCR100-004 designation corresponds to bulk box shipping, while tape and reel options utilize distinct suffixes such as RL or RLM. Confirm that the procurement order matches the required mechanical style and shipping format before finalizing the purchase.

Selection Notes

Select this component when a 200 V blocking voltage and 0.8 A RMS current capacity are required for AC switching tasks. Ensure the application environment remains within the -40°C to 110°C junction temperature range. Verify that the load characteristics do not exceed the 10 A non-repetitive surge current limit during turn-on transients.

Part Context

This part belongs to the MCR100 series of sensitive gate silicon controlled rectifiers manufactured by ON Semiconductor. The series covers blocking voltages from 100 V to 600 V, with the MCR100-004 specifically rated for 200 V. These devices are engineered for cost-effective integration into consumer electronics requiring reliable phase control or switching functions.

Replacement Considerations

Compatible substitutes include other MCR100 variants with matching voltage ratings, such as the MCR100-3 (100 V) or MCR100-6 (400 V), provided the voltage margin is acceptable. Cross-manufacturer equivalents like the MCR100G-4-B-T92-K may be considered if pinout compatibility and electrical parameters align with the original design requirements.
