SFH6156-2T

Overview

The SFH6156-2T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductors. It features an NPN phototransistor output with a current transfer ratio ranging from 63% to 125%. The device supports a maximum forward current of 60 mA and a collector current of 100 mA, with a collector-emitter voltage rating of 70 V. It provides high isolation capability at 5300 Vrms. The component operates within a temperature range of -55°C to +100°C and is housed in a compact SMD-4 surface-mount package.

Feature Summary

• High insulation voltage of 5300 Vrms for robust electrical isolation
• NPN phototransistor output configuration for standard switching applications
• Surface-mount SMD-4 package design for automated assembly integration

Applications

• General-purpose signal isolation in industrial control systems
• Power supply feedback loops requiring high isolation ratings
• Microcontroller interface circuits for noise immunity

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation aligns with Vishay Semiconductor Opto Division specifications. Ensure compliance with RoHS directives as documented in official product datasheets prior to procurement.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed characteristics is required. The 63-125% CTR range accommodates various input drive conditions. Consider the SMD-4 footprint constraints and thermal dissipation limits of 150 mW during circuit layout planning.

Part Context

This part belongs to the SFH series of transistor output optocouplers from Vishay. It shares the same physical package and basic electrical architecture with variants like SFH6156-2, differing primarily in packaging format and potentially binning criteria. The series targets cost-effective isolation solutions for consumer and industrial electronics.

Replacement Considerations

Direct substitutes include SFH6156-2 (tube packaging) or SFH6156-2X001 (tube packaging). Verify pinout compatibility and CTR binning requirements before substitution. Alternative packages may require mechanical rework.
