SFH640-3X007

Overview

The SFH640-3X007 is a single-channel transistor output optocoupler from Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a base connection, housed in a 6-SMD gull-wing package. The device provides high isolation voltage of 5300 Vrms and supports DC input. Key electrical parameters include a maximum collector-emitter voltage of 300 V, maximum collector current of 50 mA, and forward current of 60 mA. The current transfer ratio ranges from 100% to 200%, with a typical rise time of 3 µs and fall time of 14 µs. Operating temperature spans -55°C to +115°C.

Feature Summary

• High isolation voltage capability for safe signal transmission between isolated circuits
• Integrated base pin on the phototransistor output for enhanced switching speed control
• Surface-mount packaging design suitable for automated assembly processes

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Signal isolation in communication interfaces

Procurement Notes

Verify the specific suffix X007 confirms the 6-SMD gull-wing package configuration. Ensure the procurement specification matches the required isolation voltage rating of 5300 Vrms for the target application safety standards. Confirm RoHS compliance status if restricted substances are a constraint. Cross-reference the manufacturer part number with official Vishay documentation to avoid confusion with similar series components like SFH640-3.

Selection Notes

Select this component when high voltage isolation and fast switching speeds are critical. The integrated base allows for improved turn-off times compared to standard phototransistors. Consider the surface-mount form factor for space-constrained PCB designs. Evaluate the 300 V collector-emitter voltage rating against the load requirements. Ensure the operating temperature range meets the environmental conditions of the end product.

Part Context

This component belongs to the SFH640 series of transistor output optocouplers. It shares architectural similarities with through-hole variants like the SFH640-3 but utilizes a surface-mount package. The series is designed for general-purpose isolation applications where reliability and speed are prioritized over cost-sensitive mass production.
