ISP845SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISP845SMT&R is a quad-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output configuration with a high isolation voltage of 5300Vrms. The device supports a maximum DC forward current of 50 mA and offers a minimum current transfer ratio of 600% at 10 mA input. It is housed in a 16-pin surface mount package designed for reliable signal transmission across isolated circuits.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Quad-channel architecture for multi-signal isolation
• Darlington output stage for high gain
• High voltage isolation capability
• Surface mount packaging for automated assembly

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring multi-channel isolation
• Signal interface between microcontrollers and power stages
• Data acquisition systems with galvanic isolation requirements

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation, as Isocom Components may distribute products originally designed by other semiconductor manufacturers. Confirm the specific suffix 'R' indicates reel packaging if required for your assembly line. Ensure the component status is active for new designs, as obsolescence can impact long-term supply chain stability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are needed in a compact surface mount footprint. The Darlington output provides higher current drive capability compared to standard transistor outputs, suitable for driving relays or LEDs directly. Verify that the 5300Vrms isolation rating meets the safety standards of your target application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the family of quad-channel optocouplers. Similar variants include the ISP845-1SMT&R and bulk tube versions like the ISP845X. These devices share the same core electrical characteristics but differ in packaging format (tape and reel vs. tube) and minor pinout variations depending on the specific sub-model.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes should be verified against the datasheet for pin compatibility and electrical ratings. Generic quad-channel Darlington optocouplers may serve as alternatives if isolation voltage and CTR specifications are matched.
