HCPL-817-06DE

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-817-06DE is a single-channel transistor output optocoupler manufactured by Broadcom Limited. It features an NPN phototransistor output and operates with a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA. The device provides 5000 Vrms isolation voltage between input and output. Electrical characteristics include a forward voltage of 1.4 V at 50 mA forward current, and a current transfer ratio ranging from 300% to 600%. Typical switching times are 4 µs for rise time and 3 µs for fall time. The component is housed in a PDIP-4 package and supports through-hole mounting.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 06DE to confirm the 70 V collector-emitter voltage rating and 300%-600% CTR range, as other variants in the HCPL-817 series may have different voltage or performance specifications. Ensure the procurement documentation explicitly states the PDIP-4 package and RoHS compliance status. Cross-reference the manufacturer part number with official Broadcom datasheets to validate technical parameters before ordering.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a 70 V output voltage rating is required, distinguishing it from lower-voltage variants in the same family. The 5000 Vrms isolation makes it suitable for applications demanding robust noise immunity. Consider the typical 4 µs rise time for speed requirements. Verify that the through-hole PDIP-4 package fits the target PCB design constraints compared to surface-mount alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL-817 series of high-density phototransistor optocouplers. The series is characterized by its small footprint and reliable optical coupling performance. Broadcom designs these components to provide effective electrical isolation in space-constrained environments while maintaining standard transistor output characteristics for easy integration into existing circuit topologies.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the HCPL-817 series include HCPL-817-W00E, though users must verify if the W00E variant meets the specific 70 V collector-emitter voltage requirement, as some sources indicate lower ratings for certain suffixes. Other generic NPN phototransistor optocouplers with similar isolation and pinout may serve as functional replacements if exact matching is not critical.
