Overview
The ISP817XCG is a single-channel, through-hole phototransistor optocoupler manufactured by Isocom Components. It features a DIP-4 package with DC input and NPN phototransistor output. Key electrical parameters include a maximum forward voltage of 1.4V, a maximum input current of 50mA, and an isolation voltage of 5300 Vrms. The device exhibits typical rise and fall times of 4µs and 3µs respectively, with a minimum current transfer ratio of 20% and a maximum of 600%.
Feature Summary
- Provides high-density mounting capability for space-constrained circuit designs.
- Offers robust electrical isolation via a 5300 Vrms dielectric barrier between input and output circuits.
- Features a standard NPN phototransistor output suitable for logic-to-logic interfacing.
Applications
- Logic-to-logic isolation in noisy industrial environments.
- Line receiver applications for signal transmission.
- Digital control interfaces for computer peripherals.
Procurement Notes
Verify the specific suffix 'XCG' against official manufacturer documentation to confirm exact binning or tape-and-reel specifications. Ensure the component meets required UL and VDE recognition standards for the target application. Cross-reference datasheet limits with system requirements before finalizing procurement orders.
Selection Notes
Select this component when a single-channel DC-input isolator with a phototransistor output is required. Consider the 5300 Vrms isolation rating for safety-critical applications. Evaluate the CTR range (20%-600%) to ensure compatibility with downstream logic levels. Verify that the DIP-4 package fits the PCB layout constraints.
Part Context
The ISP817XCG belongs to the ISP817 series of high-density mounting phototransistor optically coupled isolators from Isocom Components. This series serves as a replacement for various industry-standard components, offering comparable performance in a compact plastic DIP package. The product line is designed for commercial applications requiring reliable galvanic isolation.
Replacement Considerations
