HCPL4502WV

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL4502WV is a single-channel high-speed optocoupler manufactured by onsemi, housed in an 8-pin Widebody DIP (MDIP-8) surface-mount package. It features a diode-transistor architecture that utilizes separate connections for the photodiode bias and output-transistor collector to minimize base-collector capacitance, achieving data rates up to 8 Mb/s. Key electrical specifications include a 5000 Vrms isolation voltage, a typical current transfer ratio of 15%, and a maximum forward current of 25 mA. The device operates within a temperature range of 0°C to +70°C and dissipates up to 100 mW.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High-speed operation enabled by integrated photodiode biasing which reduces base-collector capacitance
• Widebody DIP-8 package design providing enhanced creepage and clearance distances
• Single-channel configuration with transistor output for digital signal isolation

Transistor, Photovoltaic Output Optoisolators Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems needing robust noise immunity
• Power supply feedback loops in switching regulators

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'WV' corresponds to the Widebody DIP-8 package and lead-free RoHS compliance status as defined by onsemi. Confirm that the 8 Mb/s speed rating applies to your specific operating conditions and load requirements. Ensure the procurement source provides official datasheets matching the HCPL4502 series documentation to validate insulation voltage and thermal characteristics.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed data transmission (up to 8 Mb/s) is required alongside significant isolation voltage. The widebody package is suitable for applications demanding higher creepage distances than standard SO-8 packages. Consider the 15% CTR minimum when designing drive circuits for the output transistor to ensure reliable switching across the specified temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-4502/4503 family of single-channel high-speed optocouplers from onsemi. These devices are designed to replace slower conventional phototransistor couplers in high-frequency applications. The family shares the same internal LED and photodetector structure but differs in packaging options such as standard DIP, SO-8, and the widebody variant found in this model.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the HCNW4502#300 from Broadcom, which offers identical pinout and performance characteristics in a similar widebody DIP-8 package. Verify that any replacement maintains the 8 Mb/s data rate and 5000 Vrms isolation rating.
