Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6N135S(TA)-V is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Isolation voltage: 5000Vrms
• Number of channels: 1
• Output type: Transistor with Base
• Package type: 8-SMD, Gull Wing
• Input type: DC
• Maximum output voltage: 20V
• Output current per channel: 8mA
• Forward voltage (Vf): 1.45V
• Maximum DC forward current: 25mA
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Parameter Variations:

• Current Transfer Ratio (Min): 7% to 19% @ 16mA
• Current Transfer Ratio (Max): 50% (fixed)
• Turn On/Turn Off Time: 150ns to 350ns / 260ns to 500ns
• Operating Temperature Range: -55°C to -40°C (minimum), 100°C (maximum)

Substitute parts must maintain all mandatory parameters while operating within the allowable variation ranges. Parts meeting these criteria are classified as direct substitutes or parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Equivalent):

The 6N136SDVM (onsemi) and 6N136SMT&R (Isocom) are direct substitutes for the 6N135S(TA)-V. Both parts maintain identical isolation voltage, channel configuration, output type, and package specifications. The 6N136 variants feature improved Current Transfer Ratio minimum (19% vs. 7%) and faster switching times (250ns/260ns vs. 350ns/500ns). The 6N136SDVM operates within a narrower temperature range (-40°C to 100°C) compared to the primary part (-55°C to 100°C); this difference is acceptable for applications not requiring extended low-temperature operation.

Parametric Equivalent:

The 6N135SMT&R (Isocom) is a parametric equivalent with identical Current Transfer Ratio specifications (7% to 50%) and operating temperature range (-55°C to 100°C) as the 6N135S(TA)-V. This part provides direct compatibility for applications requiring the lower CTR minimum specification. Switching time data is not provided for this variant.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements. All parts are classified as Active products with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the 6N136SDVM replace the 6N135S(TA)-V in all applications?

A: The 6N136SDVM is a direct substitute for most applications. The primary difference is the operating temperature minimum: 6N136SDVM operates from -40°C, while 6N135S(TA)-V operates from -55°C. If your application requires operation below -40°C, the 6N135S(TA)-V or 6N135SMT&R must be used. All other electrical and mechanical parameters are compatible.

Q: What is the significance of the Current Transfer Ratio (CTR) difference between 6N135 and 6N136 variants?

A: The 6N135 series has a CTR minimum of 7%, while the 6N136 series has a CTR minimum of 19%. Both share the same maximum of 50%. The higher minimum CTR of the 6N136 indicates tighter performance specification and faster optical coupling efficiency. For applications sensitive to CTR variation, the 6N136 provides more consistent performance. The 6N135 is suitable for applications with broader CTR tolerance.

Q: Are there package differences between these substitute parts?

A: No. All substitute parts use the identical 8-SMD, Gull Wing package configuration. They are pin-compatible and can be used interchangeably on the same PCB layout without modification.

Q: What does MSL rating 1 (Unlimited) mean for component handling?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required before soldering, simplifying supply chain management.

Q: Can I use 6N135SMT&R as a substitute if I need the extended temperature range?

A: Yes. The 6N135SMT&R maintains the same operating temperature range (-55°C to 100°C) and CTR specifications (7% to 50%) as the 6N135S(TA)-V. This part is suitable for applications requiring the lower temperature minimum. Switching time specifications are not provided for this variant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—6N136SDVM, 6N136SMT&R, and 6N135SMT&R—are ROHS3 compliant, matching the compliance status of the 6N135S(TA)-V.
