PC814X1

Transistor, Photovoltaic Output Optoisolators Overview

The PC814X1 is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features a GaAs infrared LED coupled to an NPN phototransistor within a 4-DIP package. The device provides electrical isolation with a rated insulation voltage of 5000Vrms. Key electrical parameters include a collector-emitter voltage (Vceo) of 80V, a maximum forward current (If) of 10mA, and a typical forward voltage (Vf) of 1.2V. The phototransistor supports a collector current of 50mA with a saturation voltage of 200mV. The unit operates within a temperature range of -30°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix of the part number, as variations such as PC814X1CSZ9F or PC81410NSZ0F indicate different packaging or regional specifications. Confirm RoHS compliance status directly from the manufacturer's documentation, as it varies by production batch. Ensure the procurement source provides valid datasheets matching the exact component designation to avoid receiving obsolete or non-compliant variants.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a cost-effective, single-channel isolation solution is required for low-speed signal transmission. The 80V collector-emitter voltage rating suits most low-voltage logic interfacing applications. Consider the rise and fall times if the application involves higher frequency signals, as standard transistor outputs may limit bandwidth compared to faster optocoupler types.

Transistor, Photovoltaic Output Optoisolators Part Context

The PC814X1 belongs to the broader PC814 series of optocouplers produced by Sharp Microelectronics. This series is widely recognized for its reliability in industrial and consumer electronics. While the base model PC814X1 is common, specific suffixes denote variations in lead plating, tape-and-reel packaging, or environmental certifications, requiring careful identification during design integration.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include HCPL-814-000E and HCPL-814-00AE from Broadcom Limited. These alternatives offer similar functional characteristics and pin configurations, facilitating direct replacement in existing designs where the original Sharp component is unavailable.
