HCPL4503SVM

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL4503SVM is a single-channel high-speed optocoupler manufactured by onsemi, housed in an 8-SMD surface-mount package. It features a transistor output with base and provides electrical isolation of 5000 Vrms. The device supports data rates up to 1 Mb/s with typical rise and fall times of 800 ns. Key electrical parameters include a forward current of 16 mA, forward voltage of 1.45 V, and output current of 8 mA. The operating temperature range spans from -55°C to +100°C, ensuring reliability in demanding environments.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-speed signal transmission with a data rate capability of 1 Mb/s for efficient digital communication.
• Offers robust electrical isolation via an insulating layer between the LED input and photodetector output.
• Integrates a phototransistor with a base terminal to facilitate controlled switching and improved performance.

Transistor, Photovoltaic Output Optoisolators Applications

• High-speed data communication interfaces requiring galvanic isolation
• Industrial control systems for noise immunity
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation as onsemi, as Fairchild Semiconductor was acquired. Confirm the specific suffix 'SVM' corresponds to the 8-SMD鸥翼 (gull-wing) package variant. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding assembly or material declarations before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel high-speed optocoupler with a transistor output is required. The 8-SMD package suits surface-mount applications. Consider the 5000 Vrms isolation rating for safety-critical circuits. Compare against the HCPL4503SM if through-hole DIP packaging is preferred instead of surface mount.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the HCPL4503M series of high-speed optocouplers. It is functionally related to the legacy Agilent/HP HCPL-4503 but updated for modern manufacturing processes. The device is part of onsemi's portfolio of isolated interface solutions designed for reliable signal transfer across potential barriers.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL4503SM is a verified alternative within the same family, differing primarily in the DIP-8 through-hole package versus the SMD configuration. Other substitutes may exist within the broader HCPL4503 series, but pin compatibility and package type must be validated.
