SL55113SD

Overview

The SL55113SD is a photovoltaic output optoisolator manufactured by onsemi, designed for high-voltage isolation applications. It features a single channel with an input-output isolation voltage of 5300Vrms. The device utilizes a transistor output configuration with a base terminal for enhanced control and switching capabilities. Key electrical parameters include a minimum current transfer ratio of 25% at a forward current of 2mA. Typical turn-on and turn-off times are specified for standard operating conditions. The component is housed in a compact 6-SMD surface-mount package, suitable for space-constrained circuit designs requiring robust galvanic isolation.

Procurement Notes

Verify the obsolete status of this specific part number before initiating procurement processes. Confirm availability through authorized distributors or secondary market suppliers as direct manufacturer orders may not be supported. Ensure that any substitute components meet the same isolation voltage and package footprint requirements to maintain system integrity and regulatory compliance.

Selection Notes

Select this component when high isolation voltage is critical and a photovoltaic output is preferred over traditional transistor outputs. Consider the 6-SMD package size for board space limitations. Evaluate the need for a base terminal if active pull-down or faster switching characteristics are required compared to standard phototransistor isolators without base access.

Part Context

This device belongs to the family of photovoltaic output optoisolators from onsemi, which are engineered for applications demanding superior dielectric strength and low leakage currents. These components typically serve as reliable interfaces between low-voltage digital logic and high-voltage power stages, ensuring user safety and equipment protection in electrically noisy environments.

Replacement Considerations

As the SL55113SD is marked obsolete, verify equivalent parts with matching 5300Vrms isolation and 6-SMD packaging. Ensure substitutes support photovoltaic output characteristics and base terminal functionality if present in the original design.
