ISP817C

Transistor, Photovoltaic Output Optoisolators Overview

The ISP817C is a single-channel phototransistor output optocoupler manufactured by Isocom Components. It features a DIP-4 package with through-hole mounting. The device provides an isolation voltage of 5300 Vrms. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4µs, and a typical fall time of 3µs. The collector-emitter breakdown voltage is specified at a minimum of 35V. The unit supports DC input current up to 50mA.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-density optical isolation between input and output circuits using a phototransistor output stage.
• Features a compact four-pin dual in-line package designed for standard through-hole PCB mounting.
• Includes internal circuitry optimized for direct interface with logic families without requiring external pull-up resistors.

Transistor, Photovoltaic Output Optoisolators Applications

• Logic-to-logic isolation in noisy industrial environments
• Line receiver circuits
• Computer and peripheral device interfaces

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific Current Transfer Ratio (CTR) grade required for the application, as Isocom offers multiple CTR variants within the ISP817 series. Confirm that the DIP-4 lead form matches the target footprint. Ensure compliance with UL and VDE standards if used in certified equipment. Check RoHS status for environmental regulations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel of high-voltage isolation is needed with a phototransistor output. Compare against other CTR grades in the ISP817 family if higher gain is required. Consider the ISP827 or ISP847 if multiple channels are necessary. Verify thermal limits and operating temperature range against system requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP817C belongs to the ISP817 series of high-density mounting phototransistor optically coupled isolators from Isocom Components. This series serves as a replacement for industry-standard components like the PC817. The 'X' suffix typically denotes specific approval ratings such as UL and VDE recognition.
