Overview
The MCR100-3G is a sensitive gate Silicon Controlled Rectifier (SCR) manufactured by onsemi, designed for high-volume line-powered consumer applications. It features a peak repetitive off-state voltage of 100 V and an on-state RMS current rating of 0.8 A at 80°C. The device supports a peak non-repetitive surge current of 10 A and includes specified minimum and maximum values for gate trigger current, gate trigger voltage, and holding current to facilitate design flexibility. It utilizes a glass-passivated surface for reliability and is supplied in a TO-92 plastic package.
Feature Summary
- Sensitive gate architecture enables triggering by microcontrollers and logic circuits
- Glass-passivated surface ensures reliability and uniformity
- Specified minimum and maximum gate trigger and holding parameters 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 to confirm the package style and shipping quantity. The 'G' suffix indicates a lead-free package configuration. Confirm the exact shipping format, such as bulk box or tape and reel, against the manufacturer's official ordering information table to ensure compatibility with automated insertion equipment requirements.
Selection Notes
Select this component when a low-cost, sensitive gate SCR is required for line-powered consumer electronics. Ensure the application voltage does not exceed the 100 V blocking rating. Verify that the thermal management strategy accommodates the specified junction-to-case thermal resistance and RMS current derating curves for the intended operating temperature range.
Part Context
This part belongs to the MCR100 series of reverse blocking thyristors produced by onsemi. The series offers various voltage ratings ranging from 100 V to 600 V, distinguished by their suffix codes. The MCR100-3G specifically denotes the 100 V variant within this family, sharing common physical dimensions and electrical characteristics with other members of the series while differing primarily in its voltage blocking capability.
Replacement Considerations
Compatible replacements include other MCR100 series variants with identical or higher voltage ratings, such as MCR100-4G or MCR100-6G, provided the lower voltage rating meets the circuit requirements. Cross-manufacturer equivalents must be verified for matching pinout configurations, gate trigger specifications, and thermal performance characteristics.
