Dual-channel optocoupler phototransistor offers a space-saving solution

Würth Elektronik has extended its WL-OCPT optocoupler product family with the DIP-8 design. These two-channel optocoupler phototransistors with eight pins are available now. This design includes two circuits inside a single component created from two input LEDs and two output phototransistors, therefore, two separate circuits can be controlled with a single component. The family provides a stable current transfer ratio (CTR) over the full operating temperature range (-55C to +110C). The DIN-EN-60747-5-5-certified components provide an insulation voltage of 5000V, a collector-emitter voltage of 80V, and a maximum forward current of 60mA.

The optocouplers are ideal for optical and space-saving galvanic isolation in power supplies, chargers, computers, microprocessors, machines, instruments, ammeters or smart meters. Binning of the dual-channel device is in a CTR range of 130-400%, tested at an input current of 5mA and a collector-emitter voltage of 5V. Depending on the land pattern on the PCB, the DIP-8 optocoupler packages are offered in standard, M, S and SL leadframe variants. The lead frames are constructed of copper, thus guaranteeing the best solderability.

Like all other series optocouplers, the DIP-8 variants are now available from stock with no minimum order quantity.
