Product details

The STMicroelectronics X0115ML is a sensitive-gate SCR thyristor rated for 600 V off-state blocking and 800 mA RMS on-state current. The sensitive gate (150 µA max gate trigger current) lets a microcontroller output or optocoupler drive it directly — no driver transistor needed, which shrinks the BOM on low-power phase-control or AC switching boards. Packaged in a SOT-23-3 surface-mount case, it fits compact designs where board space is tight.

The 600 V off-state voltage provides margin for 120V AC and 240V AC line switching. The 500 mA average on-state current (800 mA RMS) handles small loads: relays, solenoids, indicator lamps, valve coils.

Package and storage

The X0115ML comes in a SOT-23-3 package (also known as TO-236-3 or SC-59). Store the reels in a dry cabinet or with desiccant; the small body is not moisture-sensitive by default, but keeping the reel sealed avoids any reflow issues.

Frequently asked questions

Can X0115ML be used for 120V AC switching?

Yes. The 600 V off-state rating provides ample margin for 120V AC line switching. The 800 mA RMS on-state current handles typical small loads like relays, solenoids, and indicator lamps on a 120V AC circuit.

Is X0115ML equivalent to MCR100-6?

The X0115ML and MCR100-6 are both sensitive-gate SCRs in SOT-23 packages with similar ratings (600 V, 0.8 A). The MCR100-6 is a common industry part; the X0115ML is a functional equivalent for most low-power AC switching applications. Verify the gate trigger current and holding current against your circuit — the X0115ML specifies 150 µA max Igt and 5 mA max Ih, which are in the same range as the MCR100-6.
