PS2501-4G

Overview

The PS2501-4G is a 4-channel optocoupler from the PS2501 series manufactured by Isocom Components. It features a DIP-16 package with through-hole mounting. The device accepts AC input and provides transistor DC output. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4μs, and a typical fall time of 3μs. It offers an isolation voltage of 5300Vrms and operates within a temperature range of -30°C to 100°C. The unit is UL certified.

Feature Summary

• Provides four independent channels for signal isolation in a single component
• Designed for AC input applications with transistor DC output configuration
• Offers high isolation voltage capability for safety-critical circuits

Applications

• Industrial control systems requiring multi-channel isolation
• Power supply protection circuits
• Smart metering and utility instrumentation

Procurement Notes

Verify that the specific suffix 'G' corresponds to the intended packaging or compliance variant as defined by the manufacturer's current documentation. Confirm that the AC input specification aligns with your circuit design requirements, as this differs from standard DC-input variants in the same series. Ensure the DIP-16 footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when multiple isolated channels are required within a compact DIP-16 form factor. The AC input characteristic distinguishes it from DC-input alternatives like the TLP521 series. Consider the 5300Vrms isolation rating for applications demanding robust barrier protection between high-voltage and low-voltage domains.
