HCPL-4534-020E

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-4534-020E is a dual-channel high-speed optocoupler manufactured by Broadcom Limited. It integrates two light-emitting diodes with integrated phototransistor detectors, providing electrical isolation between input and output circuits. The device features a data rate of 1 Mb/s and an insulation voltage of 5000 Vrms. It operates within a temperature range of -55°C to +100°C and utilizes a PDIP-8 Gull Wing package for surface mount or through-hole installation.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high common mode transient immunity of 15,000 V/µs minimum at VCM= 1500 V
• Offers up to 100 times speed increase over conventional phototransistor optocouplers
• Compatible with infrared vapor phase and reflow soldering processes

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial automation control systems
• Power supply feedback loops
• Signal isolation in noisy environments

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '020E' against official Broadcom documentation to confirm the exact insulation rating and packaging configuration. Ensure compatibility with the target PCB footprint and thermal management requirements. Cross-reference the RoHS status and lead time directly with authorized distributors or the manufacturer's current product announcements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The 1 Mb/s data rate suits applications needing faster response than standard optocouplers. Consider the 5000 Vrms isolation barrier for safety-critical interfaces. Evaluate the PDIP-8 package constraints against available board space and mounting preferences.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-M453 series of dual-channel optocouplers. It shares architectural similarities with the HCPL-2531 but offers enhanced common mode transient immunity. The series is designed for applications requiring reliable signal transmission across isolated boundaries with minimal propagation delay.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

HCPL-4534-500E: Verify if the 3750 Vrms rating meets system isolation requirements compared to the 5000 Vrms of the 020E variant.
