# 6N137S-TA1 (Component) ## Description High-Speed Logic Output Optocoupler – Single-channel high-speed optocoupler designed for digital signal isolation, industrial automation, PLCs, motor drives, switching power supplies, data communication, microcontroller interfaces, and embedded control systems. Features an open-collector TTL-compatible output with a 15 MBd data rate, 5 kVrms isolation voltage, and 10 kV/µs minimum common-mode transient immunity (CMTI) for reliable operation in noisy electrical environments. Provides 75 ns maximum propagation delay, 22 ns typical rise time, 6.9 ns typical fall time, and supports up to 50 mA output current. The input consists of a GaAs infrared LED with a 1.38 V typical forward voltage and 20 mA maximum forward current. Operates from a 4.5 V to 5.5 V output-side supply, over a −40°C to +85°C temperature range, and is housed in a compact 8-pin SOIC (SMD) package for space-efficient PCB designs. #LiteOn #6N137STA1 #6N137 #Optocoupler #LogicOptocoupler #DigitalIsolation #HighSpeedIsolation #IndustrialAutomation #MotorDrive #PLC #EmbeddedSystems ## Component Details - **Owner:** silicon-yard - **Created:** 8/3/2026 - **Last Updated:** 8/3/2026 - **Visibility:** Public - **Symbol Style:** parametric-v1 - **Part Type:** Isolator - **Manufacturer Name:** Lite-On - **Manufacturer Part Number:** 6N137S-TA1 - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/411045f72e01ce12cc67dd53909bf09484490f27e82f994b0c9820d577039426.pdf - **Used in:** 1 project ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
