FOD8153S

Overview

The FOD8153S is a single-channel photovoltaic output optoisolator manufactured by onsemi. It features a GaAsP infrared LED coupled to a photovoltaic detector, providing electrical isolation with a maximum insulation voltage of 5000 Vrms. The device utilizes a 4-SMD surface-mount package and supports a continuous forward current of 60 mA with a typical forward voltage of 1.2 V. Designed for high-reliability applications, it operates within a temperature range of -40°C to +100°C.

Feature Summary

• Photovoltaic output architecture generates open-circuit voltage without requiring external bias power
• High isolation capability rated at 5000 Vrms for robust circuit separation
• Surface-mount SMD-4 package design facilitates automated assembly processes

Applications

• Solid-state relay driver circuits
• Microcontroller input isolation interfaces
• Industrial communication bus protection

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout configuration and packaging type. Ensure compliance with RoHS directives as indicated in manufacturer documentation. Cross-reference ordering information with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when zero-bias output detection is required for isolated signal transmission. Consider the photovoltaic nature for low-power logic interfacing where traditional transistor outputs are unsuitable. Evaluate thermal management requirements based on the specified operating temperature range and power dissipation limits.

Part Context

This part belongs to the FOD8153 series of optocouplers, distinguished by its photovoltaic output stage rather than standard transistor or logic gate outputs. It serves as a specialized isolation solution for applications demanding high common-mode transient immunity and galvanic separation without active output circuitry.

Replacement Considerations

Direct substitutes include other photovoltaic output optocouplers from manufacturers such as Broadcom (HCPL-7840) or Vishay (VOF8153). Verify equivalent isolation voltage ratings and package dimensions to ensure mechanical compatibility during replacement.
