VOW137-X017T

Overview

The VOW137-X017T is a single-channel logic output optoisolator from Vishay. It features a GaAs infrared emitting diode coupled to an integrated open-collector photo-detector. Key electrical parameters include a data rate of 10MBd, isolation voltage of 5300Vrms, and common-mode transient immunity of 10kV/µs. Propagation delays are 100ns max (tpLH/tpHL), with rise/fall times of 14ns/7ns typical. It operates on 4.5V to 5.5V supply, supports 20mA max forward current, and handles 50mA output current per channel within -40°C to 100°C temperature range.

Feature Summary

• High-speed digital signal transmission capability via integrated logic output structure
• Enhanced noise immunity provided by high common-mode transient rejection rating
• Wide operating temperature range suitable for industrial environments
• Compact surface-mount packaging design for automated assembly integration

Applications

• Industrial communication bus interfaces requiring galvanic isolation
• Microcontroller input/output isolation in noisy electromagnetic environments
• Power supply feedback loop isolation circuits
• Signal level shifting between different voltage domains

Procurement Notes

Verify the specific suffix X017T corresponds to the required tape-and-reel or cut-tape packaging format before ordering. Confirm that the 8-SMD鸥翼 package dimensions match your PCB footprint exactly. Ensure the 5300Vrms isolation rating meets your safety certification requirements. Check RoHS compliance status against current regulatory standards for your target market. Validate supplier authenticity through authorized distribution channels only.

Selection Notes

Choose this component when high-speed digital isolation exceeding 10MBd is required alongside robust noise immunity. The open-collector output necessitates external pull-up resistor configuration compatible with the target logic voltage levels. Consider the 100ns propagation delay limits for timing-critical applications. Evaluate thermal management needs given the 100°C maximum junction temperature specification during continuous operation.

Part Context

This device belongs to Vishay's VOW family of wide-body optocouplers designed for high-isolation applications. The series emphasizes enhanced creepage and clearance distances compared to standard packages. It serves as a modern replacement for legacy high-speed isolators while maintaining compatibility with existing circuit topologies. The family includes dual-channel variants like VO2631 for multi-line isolation needs.

Replacement Considerations

Publicly confirmed substitute part numbers include 6N137-X007T and 6N137A-X017T from the same manufacturer. These alternatives share similar pinouts and functional characteristics but may differ in specific electrical tolerances or packaging options. Verify datasheet specifications carefully before substitution to ensure performance parity.
