OC1D Series
High Power Transfer Efficiency PV-Output Optocouplers
Description
OC1D is a series of photovoltaic-output optocouplers that achieve unprecedented power transfer efficiency in a very small footprint. The devices employ Polaris Semiconductor’s patented monolithic GaAs-based optocoupler technology, achieving electrical isolation with high current transfer ratio and power transfer efficiency over a wide range of drive currents.
Each optocoupler in the OC1D series has an LED element operating at forward voltages of 1.2V to 1.7V and drive currents of 0.5mA to 500mA. The PV element has an open-circuit voltage in the range of 1.0V to 1.2V. These optocouplers can be configured in various series/parallel strings for myriad applications in power management and beyond. Their high current transfer ratio is particularly suited to DC voltage conversion via our patented Enhanced Linear Regulator topology, and they can also be used to supply high currents in MOSFET gate driving.
Specifications
| Device | Optocouplers per Package1 | Peak Efficiency | Package | Package Dimensions |
|---|---|---|---|---|
| OC1DQ16 | 1 | 52% | QFN-16 | 4x4x0.8mm3 |
| OC1DS8 | 1 | 52%2 | SOIC-8 | 3.8x4.9mm2 |

1 For custom orders with multiple optocouplers per package, a larger package may be required.
2 In typical applications, actual efficiency in SOIC-8 will be lower than in QFN-16 packages due to poorer thermal performance
