Overview
The MCR100-003 is a sensitive gate silicon controlled rectifier (SCR) from the MCR100 series, manufactured by onsemi. It features a reverse blocking thyristor structure designed for high-volume line-powered consumer applications. The device operates within a junction temperature range of -40°C to 110°C and is housed in a TO-92 (TO-226AA) plastic package. Key electrical specifications include a peak repetitive off-state voltage (VDRM/VRRM) of 100 V, an on-state RMS current rating of 0.8 A at 80°C, and a peak non-repetitive surge current capability of 10 A. The component specifies minimum and maximum values for gate trigger current (IGT), gate trigger voltage (VGT), and holding current (IH) to facilitate design integration.
Feature Summary
- Sensitive gate architecture enables reliable triggering by microcontrollers and standard logic circuits.
- Glass-passivated surface construction ensures device reliability and uniformity under operating conditions.
- High dV/dt immunity rated at a minimum of 20 V/µs at 110°C to prevent false triggering.
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 package style and shipping configuration. The base part number corresponds to the TO-92 bulk packaging variant; alternative suffixes indicate tape and reel or ammo pack options. Confirm RoHS compliance status if lead-free material is required for the assembly process.
Selection Notes
Select this component when a low-cost, single-phase SCR with sensitive gate characteristics is required for line-powered loads. Ensure the circuit design accounts for the 100 V blocking voltage limit and the 0.8 A RMS current rating at the expected case temperature. Verify that the gate drive signal meets the specified IGT and VGT ranges for reliable turn-on across the full operating temperature spectrum.
Part Context
The MCR100-003 belongs to the MCR100 series of sensitive gate silicon controlled rectifiers. This series includes variants with different voltage ratings, specifically the MCR100-004 (200 V), MCR100-006 (400 V), and MCR100-008 (600 V). All variants share the same physical package and general thermal characteristics while differing in their peak repetitive off-state voltage capabilities.
Replacement Considerations
Direct functional substitutes within the same series include MCR100-004, MCR100-006, and MCR100-008, provided the higher voltage ratings are acceptable for the application. Cross-manufacturer replacements must match the TO-92 package, 0.8 A RMS current rating, and 100 V blocking voltage specifications.
