HCPL-5501#300

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-5501#300 is a high-reliability, single-channel hermetically sealed optocoupler manufactured by Broadcom Limited. It features a gallium arsenide phosphide (GaAsP) light-emitting diode coupled with an integrated phototransistor detector. The device operates within a temperature range of -55°C to +125°C and provides an isolation voltage of 1500 Vdc. Key electrical parameters include a data rate of 400 kb/s, a bandwidth of 9 MHz, and a maximum collector current of 8 mA. It utilizes a CDIP-8 Gull Wing surface-mount package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Hermetically sealed construction in a ceramic DIP package for high reliability
• Integrated base pin on the phototransistor allows for adjustable gain and bandwidth
• Enhanced radiation tolerance through shallow-depth chip photodiode design
• Compatible with TTL, LSTTL, and CMOS logic interfaces

Transistor, Photovoltaic Output Optoisolators Applications

• Military and aerospace systems requiring Class H reliability
• Industrial control systems demanding high isolation
• Medical equipment requiring secure signal transmission
• Automotive electronics operating in harsh environments

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix #300 to confirm the gull-wing surface mount configuration and solder-dipped leads. Ensure compliance with MIL-PRF-38534 Class H standards if military-grade qualification is required. Cross-reference datasheets for exact screening levels and lot traceability requirements before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside extreme environmental resilience. The integrated base terminal offers design flexibility for optimizing response time and gain. Consider the hermetic seal as critical for applications exposed to moisture or radiation where standard plastic packages may fail over time.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-5501 series of high-speed optocouplers originally developed by Hewlett Packard. The series has transitioned through Avago Technologies to Broadcom Limited. The #300 suffix specifically denotes the surface-mount variant with gull-wing leads, distinguishing it from through-hole or other lead-form options within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the 8-pin CDIP-8 hermetic package and Class H military specifications. Verify that substitute devices support the 9 MHz bandwidth and 1500 Vdc isolation rating. Check for equivalent base-terminal functionality to maintain circuit compatibility without redesigning bias networks.
