HCPL-5501

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-5501 is a high-reliability, single-channel hermetically sealed optocoupler manufactured by Broadcom Limited. It features a phototransistor output with an isolation voltage of 1500Vdc and operates within a temperature range of -55°C to +125°C. The device utilizes an 8-pin ceramic DIP package (CDIP-8) compliant with MIL-PRF-38534 Class H standards. Key electrical parameters include a maximum DC forward current of 20 mA, a typical forward voltage of 1.55 V, and a maximum output voltage of 20 V. The unit supports a channel count of one and provides robust signal isolation for demanding environments.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Hermetically sealed construction in an 8-pin ceramic DIP package ensuring long-term reliability
• Compliance with MIL-PRF-38534 Class H military standards for high-reliability applications
• Single-channel design providing galvanic isolation between input and output circuits

Transistor, Photovoltaic Output Optoisolators Applications

• Military aerospace systems requiring certified high-reliability components
• Industrial control systems operating in extreme temperature environments
• Medical equipment requiring strict isolation and safety compliance

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm package type and lead time requirements. Ensure compatibility with MIL-PRF-38534 Class H specifications for your application. Check for RoHS status if required by your procurement policy. Confirm availability through authorized distributors as this is a specialized component. Validate that the ceramic DIP package fits your PCB footprint constraints before finalizing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the HCPL-5501 when military-grade reliability and hermetic sealing are mandatory. Consider its 1500Vdc isolation rating for high-voltage noise immunity. Evaluate the 8mA output current capability against your load requirements. The wide operating temperature range suits harsh environmental conditions. Compare against non-hermetic alternatives if cost is a primary constraint but reliability is secondary.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the HCPL series of high-speed optocouplers from Broadcom Limited. It shares the family's focus on signal isolation but distinguishes itself through hermetic packaging and military certification. Unlike standard plastic-packaged variants, this model offers enhanced protection against moisture and contaminants. It serves as a bridge between low-power control signals and high-voltage isolated loads in critical infrastructure.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the CDIP-8 hermetic package and MIL-PRF-38534 Class H qualification. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage. Non-hermetic equivalents may require derating or additional environmental protection measures.
