The MCT6H / MCT62H is a dual-channel optocoupler with a phototransistor output. It features a typical current transfer ratio (CTR) of 100%, an isolation test voltage (VISO) of 5000VRMS, a low temperature coefficient of CTR, a low coupling capacitance of 0.3pF, a wide ambient temperature range, and is a lead-free component.
The MCT6H and MCT62H are dual‑channel optocouplers that combine a phototransistor with a gallium‑arsenide infrared LED in a 6‑lead plastic DIP package. They are designed for galvanically isolated circuits and non‑interacting switch applications.
Key specifications include a typical current transfer ratio (CTR) of 100 % for the MCT62H and >50 % for the MCT6H, a 5000 VRMS isolation test voltage, wide ambient temperature range (‑40 °C to +100 °C), and low coupling capacitance (≈0.3 pF). The device meets RoHS and WEEE requirements and is UL1577 certified.
| Isolation Test Voltage | 5000 VRMS |
|---|---|
| Forward Voltage (VF) at IF=50 mA | Typical 1.6 V |
| Collector‑Emitter Voltage (VCEO) | Maximum 70 V |
| Power Dissipation (Pdiss) | Typical 100 mW |
| Maximum Junction Temperature (Tj) | 125 °C |
| Turn‑On Time (ton) | 6.0 µs |
The MCT62H typically provides a current transfer ratio greater than 100 %.
The optocoupler is rated for an isolation test voltage of 5000 VRMS.
The storage temperature range is –55 °C to +125 °C.
