SFH615ABM

Overview

The SFH615ABM is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and provides high isolation voltage of 5300 Vrms. The device operates within a temperature range of -55°C to +100°C and utilizes a PDIP-4 package for through-hole mounting. Key electrical specifications include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a power dissipation rating of 150 mW. The component supports a maximum forward current of 60 mA with a typical forward voltage of approximately 1.65 V.

Feature Summary

• Provides galvanic isolation between input and output circuits via an internal LED and phototransistor structure.
• Features a robust insulation voltage rating suitable for demanding safety applications.
• Designed for through-hole installation in standard DIP-4 packages.

Applications

• Industrial control systems requiring signal isolation
• Measurement equipment needing circuit separation
• Power supply feedback loops

Procurement Notes

Verify the specific manufacturer designation when sourcing, as this component may be listed under Vishay Semiconductors or Vishay Siliconix depending on the distributor's catalog structure. Confirm that the requested part matches the exact model number SFH615ABM to ensure compatibility with the specified 5300 Vrms isolation rating and PDIP-4 package dimensions. Cross-reference datasheets to confirm RoHS compliance status and lead times if available from official channels.

Selection Notes

Select this component when high isolation voltage is required for a single-channel application. Ensure the design accommodates the PDIP-4 form factor and through-hole assembly process. Verify that the operating temperature range of -55°C to +100°C meets the environmental requirements of the target system. Consider the CTR specifications if precise gain control is necessary for the interface circuit.

Part Context

This component belongs to the family of transistor output optocouplers designed for general-purpose isolation tasks. It shares functional similarities with other models in the series but is distinguished by its specific isolation voltage rating and package type. The product line emphasizes reliability and safety certifications for industrial use cases.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material for direct replacement. Users should consult official Vishay documentation for recommended alternatives such as the VO615A series or SFH615A variants, ensuring all electrical parameters match the original design requirements.
