HCPL-4502-020E

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-4502-020E is a single-channel high-speed optocoupler from the Broadcom HCPL series, housed in an 8-pin PDIP package. It features a diode-transistor architecture with a phototransistor output. Key electrical parameters include a data rate of 1 Mb/s and an isolation voltage of 3750 Vrms. The device supports a forward current of 16 mA with a typical current transfer ratio of 25%. It operates within a temperature range of 0°C to +70°C and dissipates up to 100 mW.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides electrical insulation between input and output using an insulating layer between the LED and integrated photodetector.
• Delivers high-speed signal transmission capabilities suitable for digital communication interfaces.
• Offers TTL-compatible logic output functionality for direct interfacing with standard logic circuits.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Data communication equipment needing high-speed signal transfer
• Power supply feedback loops for noise immunity

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (020E) against official Broadcom documentation to confirm compliance with regional safety standards and RoHS directives. Ensure the procurement channel sources genuine components to guarantee the specified 3750 Vrms isolation rating and 1 Mb/s data rate performance are maintained throughout the operational lifecycle.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel solution with 1 Mb/s speed and 3750 Vrms isolation is required. Compare against the HCPL-4503 if higher 5000 Vrms isolation is necessary. Consider the PDIP-8 package constraints and the 0°C to +70°C operating temperature range during circuit design integration.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL family of high-speed optocouplers manufactured by Broadcom Limited. It shares architectural similarities with the HCPL-0452 and HCPL-4503 but differs in isolation voltage ratings and specific packaging variants. The HCPL series is designed for applications demanding reliable signal transmission across isolated boundaries.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-4503-020E serves as a verified substitute offering identical 1 Mb/s speed and pinout but provides increased 5000 Vrms isolation voltage. Verify that the application circuit can accommodate the slightly different thermal characteristics if substituting directly.
