4N36S(TA)-V Equivalent & Substitute Parts

Part Overview

The 4N36S(TA)-V is an optoisolator transistor with base output manufactured by Everlight Electronics Co Ltd. This component provides galvanic isolation up to 5000Vrms with a single channel configuration in a 6-SMD surface mount package. The device is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for optoisolator applications, particularly when the primary part faces inventory constraints or when alternative sourcing is required for supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the 4N36S(TA)-V are identified based on the following critical parameters that define functional equivalence in optoisolator applications:

Primary Substitution Criteria:

• Number of Channels: 1 (single channel configuration required)
• Output Type: Transistor with Base (functional output topology)
• Package / Case: 6-SMD, Gull Wing (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Input Type: DC (signal input method)
• Current Transfer Ratio (Min): 100% @ 10mA (optical coupling efficiency)
• Vce Saturation (Max): 300mV (output transistor saturation characteristic)
• Current - DC Forward (If) (Max): 60 mA (input LED current rating)
• RoHS Status: ROHS3 Compliant (environmental and regulatory compliance)

Secondary Compatibility Parameters:

• Voltage - Isolation: Minimum 4170Vrms (isolation rating must meet or exceed application requirements)
• Voltage - Output (Max): Minimum 30V (output voltage capability)
• Voltage - Forward (Vf) (Typ): 1.18V to 1.2V (input LED forward voltage tolerance)
• Operating Temperature Range: Overlap with -40°C ~ 100°C minimum (thermal operating window)

The 4N36SM from onsemi qualifies as a substitute part based on these criteria, with the understanding that certain parameters differ within acceptable ranges for the optoisolator category.

Engineering Selection Recommendations

4N36S(TA)-V Selection Criteria:

• Applications requiring isolation voltage of 5000Vrms
• Output voltage requirements up to 80V
• Operating temperature range extending to -55°C or above 100°C
• Slower switching time tolerance (10µs turn-on, 9µs turn-off)
• Primary sourcing from Everlight Electronics Co Ltd

4N36SM Selection Criteria:

• Applications with isolation voltage requirement of 4170Vrms or lower
• Output voltage requirements up to 30V maximum
• Operating temperature range within -40°C to 100°C
• Faster switching time requirement (2µs turn-on and turn-off)
• Alternative sourcing from onsemi with higher inventory availability (22,100 pcs vs 907 pcs)
• Both parts maintain ROHS3 compliance and identical MSL rating

Substitution Feasibility: The 4N36SM is a functional substitute for the 4N36S(TA)-V only when the application circuit operates within the lower isolation voltage (4170Vrms), lower maximum output voltage (30V), and narrower temperature range (-40°C to 100°C) specifications. The faster switching characteristics of the 4N36SM do not present compatibility issues in applications designed for the 4N36S(TA)-V timing parameters.

Frequently Asked Questions (FAQ)

Q: Can the 4N36SM directly replace the 4N36S(TA)-V in all applications?

A: No. The 4N36SM has lower isolation voltage (4170Vrms vs 5000Vrms) and lower maximum output voltage (30V vs 80V). Substitution is valid only when the application circuit operates within these lower ratings. Verify isolation and output voltage requirements before substitution.

Q: What is the difference in switching speed between these parts?

A: The 4N36S(TA)-V has turn-on/turn-off times of 10µs and 9µs respectively. The 4N36SM has faster switching at 2µs for both turn-on and turn-off. Applications designed for the 4N36S(TA)-V will function with the faster 4N36SM without timing-related issues.

Q: Are the packages identical?

A: Yes. Both parts use 6-SMD, Gull Wing surface mount packages with identical mechanical and thermal characteristics. PCB layout and assembly processes are compatible.

Q: What is the operating temperature difference?

A: The 4N36S(TA)-V operates from -55°C to 110°C. The 4N36SM operates from -40°C to 100°C. If your application requires operation below -40°C or above 100°C, the 4N36S(TA)-V is required.

Q: Are both parts RoHS compliant?

A: Yes. Both the 4N36S(TA)-V and 4N36SM are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What is the current transfer ratio specification?

A: Both parts specify a minimum current transfer ratio of 100% at 10mA input current, indicating identical optical coupling efficiency.

Q: How do the forward voltage specifications compare?

A: The 4N36S(TA)-V has a typical forward voltage of 1.2V, while the 4N36SM is 1.18V. Both are within normal tolerance for optoisolator input LED specifications and are functionally equivalent.

Q: Is the 4N36SM suitable for high-voltage isolation applications?

A: The 4N36SM is rated for 4170Vrms isolation. Applications requiring 5000Vrms isolation must use the 4N36S(TA)-V. Verify your circuit isolation requirements before selecting the substitute part.
