ISP827X-2

Transistor, Photovoltaic Output Optoisolators Overview

The ISP827X-2 is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features a dual-channel configuration within a plastic DIP-8 package, providing 5300 Vrms isolation voltage between input and output circuits. The device utilizes a gallium arsenide infrared LED paired with silicon phototransistors to ensure reliable signal transmission. Key electrical parameters include a minimum collector-emitter breakdown voltage of 35 V, a maximum forward current of 50 mA, and a nominal current transfer ratio of 200%. It operates within a temperature range of -55°C to +100°C and meets UL and VDE safety standards for industrial applications.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm lead form compatibility, as 'X' specifications may denote distinct pin configurations or testing criteria compared to standard variants. Ensure that procurement documentation explicitly references the ISP827X series to guarantee adherence to the required UL and VDE certification standards for end-product compliance.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a limited board space constraint. The DIP-8 package offers a balance between channel density and thermal performance. Consider the 200% nominal current transfer ratio for efficient drive requirements. Validate that the 5300 Vrms isolation rating exceeds the system's transient voltage requirements and that the operating temperature range aligns with the environmental conditions of the target application.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP817/ISP827/ISP847 family of high-density phototransistor optocouplers from Isocom Components. The family differentiates primarily by channel count: single (ISP817), dual (ISP827), and quad (ISP847). The 'X' suffix indicates specific mechanical lead forms and associated regulatory approvals. This series is designed for surface-mount and through-hole integration where space efficiency and robust isolation are critical design factors.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct cross-replacement requires matching the dual-channel DIP-8 form factor and 5300 Vrms isolation rating. Verify equivalent current transfer ratios and breakdown voltages. Consult the manufacturer's substitution guide for approved alternatives that maintain UL/VDE certification status without altering the PCB footprint.
