MCR100-6 SCR Thyristor

Description

SUPERWAY MCR100-6 SCR Thyristor is a silicon-controlled rectifier designed for electronic switching and control applications. An SCR is a semiconductor device that can be triggered into its conducting state through its gate terminal. Once triggered, it generally continues conducting until the current falls below its holding-current level. This operating behaviour makes it useful in compatible control circuits that require a triggered switching action.

The MCR100-6 is commonly specified as a sensitive-gate SCR with a maximum repetitive off-state voltage of 400 V and an RMS on-state current rating of 800 mA. These values are manufacturer-datasheet ratings and must be checked against the exact version being used.

SUPERWAY MCR100-6 is intended for suitable electronic circuits where a sensitive gate allows the device to be triggered using a relatively small control current. The gate terminal receives the triggering signal, while the anode and cathode form the main current path. The device is not an ordinary transistor or MOSFET; its latching behaviour makes it suitable for particular switching and control functions.

The MCR100-6 SCR is documented for applications such as electronic ballasts, igniters and general-purpose switching circuits. Similar sensitive-gate SCRs may also be used in trigger circuits, sensor-controlled electronics and other low-power control applications when their ratings and switching behaviour are appropriate. The intended application should always be confirmed against the equipment’s circuit design.

SUPERWAY MCR100-6 has a compact TO-92 package in the through-hole version. This package is suitable for mounting on compatible printed circuit boards. Before installation, check the specific manufacturer’s pin configuration because terminal assignments can vary across package versions and related part numbers. The correct gate, anode and cathode connections are essential for proper circuit operation.

For repair and maintenance, the SUPERWAY MCR100-6 model marking helps identify the required type of thyristor. However, a replacement should not be selected by appearance alone. Check the repetitive blocking voltage, on-state current rating, gate trigger current, holding current, package and pinout against the original component’s datasheet.

The MCR100-6 can be used in compatible circuits that need a controlled switching device rather than a conventional transistor. Its gate-triggered operation may help a circuit respond to a control signal, but the device’s latching characteristics must be considered during circuit design. The external circuit determines how the SCR is triggered and how its current returns below the holding level.

SUPERWAY MCR100-6 SCR Thyristor is therefore a component for suitable electronic switching, triggering and control applications. Confirm the exact manufacturer’s datasheet and electrical ratings before choosing it for a new circuit or as a replacement component.
