HCPL2503S

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL2503S is a single-channel high-speed optocoupler featuring an AlGaAs LED and a phototransistor with base output. It provides 2500 Vrms isolation voltage and supports data rates up to 100 kHz. The device operates within a temperature range of -40°C to +70°C, utilizes an 8-pin surface-mount DIP package, and has a maximum forward current of 25 mA.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates a phototransistor with a dedicated base terminal for enhanced switching speed control
• Provides robust electrical isolation between input and output circuits
• Designed for high-speed digital signal transmission applications

Transistor, Photovoltaic Output Optoisolators Applications

• High-speed switching circuits requiring fast turn-off times
• Pulse transformer replacement in communication systems
• Broadband analog coupling for signal isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'S' confirms the surface-mount package variant distinct from through-hole versions. Confirm RoHS compliance status via the official datasheet before integration. Ensure the supplier provides traceable documentation matching the onsemi part number HCPL2503S to avoid counterfeit components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a phototransistor output with base access is required for precise timing control. Compare against the HCPL2531 if dual-channel capability is needed instead of single-channel. Verify that the 100 kHz frequency limit meets the system's bandwidth requirements compared to higher-speed alternatives like the HCPL4503.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the HCPL-25xx series of high-speed transistor optocouplers manufactured by onsemi. It shares architectural similarities with the HCPL-2503 (through-hole) but differs in packaging. The series is designed for applications demanding faster response times than standard logic optocouplers.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL2503 serves as a direct package-compatible alternative to the HCPL2503. For dual-channel requirements, consider the HCPL2531. Verify pinout compatibility when substituting with generic equivalents.
