6N139S(TB)-V Optoisolator Equivalent & Substitute Parts

Part Overview

The 6N139S(TB)-V is an optoisolator with Darlington output manufactured by Everlight Electronics Co Ltd. This component provides 5000Vrms isolation with a single channel configuration in an 8-SMD surface mount package. The part is currently in active production status with 1014 units available in new original stock.

Equivalent and substitute parts are identified when design requirements permit component interchange due to matching electrical and mechanical specifications. The 6N139S(TB)-V operates with a minimum current transfer ratio of 500% at 1.6mA input, maximum output voltage of 18V, and output current capability of 60mA per channel. Substitution is applicable when isolation voltage, channel count, output type, mounting configuration, and thermal operating range remain unchanged across the application.

Substitute Part Grouping Explanation

Substitution of the 6N139S(TB)-V is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 5000Vrms isolation rating is a primary substitution criterion. Any substitute must maintain identical isolation voltage specification.

Channel Configuration: Single channel (1 Channel) output is mandatory for substitution compatibility.

Output Type: Darlington with Base output configuration must be preserved. This output stage topology directly affects circuit behavior and cannot be altered in substitution.

Electrical Performance: Current transfer ratio minimum of 500% at 1.6mA input, maximum output voltage of 18V, and output current of 60mA per channel define the functional operating envelope.

Input Characteristics: DC input type with forward voltage of 1.3V typical and maximum forward current of 20mA establish input stage requirements.

Switching Performance: Turn on time of 200ns and turn off time of 1.7µs are timing specifications that must be matched.

Thermal Range: Operating temperature range of -40°C to 85°C must be maintained.

Mounting and Package: Surface mount technology with 8-SMD gull wing package configuration is required for PCB compatibility.

Compliance: ROHS3 compliance and MSL Level 1 rating must be preserved.

The 6N139S(TA) meets all these criteria and is identified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 6N139S(TA) is a direct parametric equivalent to the 6N139S(TB)-V. All electrical specifications, isolation ratings, output characteristics, timing parameters, thermal operating range, and compliance certifications are identical between the two parts.

The sole difference between these components is the packaging format. The 6N139S(TB)-V is supplied in tube packaging, while the 6N139S(TA) is supplied in tape and reel format. This distinction affects only the delivery method and component handling during assembly operations, not the functional or electrical performance of the component itself.

Both parts maintain active production status with Everlight Electronics Co Ltd and carry ROHS3 compliance certification. Selection between these two variants should be based on manufacturing process requirements and inventory management practices. Tape and reel packaging is typically preferred for high-volume automated assembly operations, while tube packaging may be selected for lower-volume or manual assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 6N139S(TA) be used as a direct replacement for the 6N139S(TB)-V in existing designs?

A: Yes. The 6N139S(TA) is a parametric equivalent with identical electrical specifications, isolation voltage, output characteristics, and timing performance. The components are functionally interchangeable at the circuit level.

Q: What is the difference between the TB and TA designations?
