4N36S(TB)-V Equivalent & Substitute Parts

Part Overview

The 4N36S(TB)-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 specified electrical and mechanical parameters while maintaining compatibility with the application circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4N36S(TB)-V is determined by the following critical parameters:

Isolation Voltage Compatibility: The main part provides 5000Vrms isolation. Substitute parts must maintain isolation voltage at or above the application requirement.

Output Configuration: Both the main part and substitutes feature transistor output with base connection, ensuring circuit topology compatibility.

Current Transfer Ratio: Minimum CTR of 100% @ 10mA is maintained across the main part and identified substitutes.

Package and Mounting: All parts use 6-SMD surface mount configuration with gull wing leads, ensuring PCB footprint compatibility.

Forward Voltage and Maximum Forward Current: Input stage parameters (Vf = 1.2V typical, If = 60mA maximum) are consistent across substitutes.

Vce Saturation: Output saturation voltage of 300mV maximum is maintained.

Compliance Status: All parts maintain ROHS3 compliance and MSL Level 1 rating.

The 4N36SM from onsemi is identified as a substitute part based on functional equivalence in output configuration, package type, and core electrical parameters, with the exception of isolation voltage rating and maximum output voltage, which are lower than the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The 4N36S(TB)-V remains the specified component when the application requires 5000Vrms isolation voltage and maximum output voltage of 80V. This part is Active status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute Part Consideration: The 4N36SM from onsemi is functionally equivalent in output stage configuration and package type. However, this substitute has reduced isolation voltage (4170Vrms versus 5000Vrms) and reduced maximum output voltage (30V versus 80V). The 4N36SM is suitable only for applications where these lower ratings are acceptable. The 4N36SM is also Active status with ROHS3 compliance and unlimited MSL rating.

Compliance and Certification: Both parts maintain ROHS3 compliance status and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring equivalent handling and storage requirements.

Temperature Operating Range: The main part operates from -55°C to 110°C, while the substitute operates from -40°C to 100°C. Application temperature requirements must fall within the selected part's operating range.

Frequently Asked Questions (FAQ)

Q: Can the 4N36SM be used as a direct replacement for the 4N36S(TB)-V?

A: The 4N36SM is functionally equivalent in output configuration and package type. However, substitution is only valid when the application isolation voltage requirement is 4170Vrms or lower and the maximum output voltage requirement is 30V or lower. If the application requires the full 5000Vrms isolation or 80V output capability of the main part, the 4N36SM is not suitable.

Q: What are the key differences between these two parts?

A: The primary differences are isolation voltage (5000Vrms for 4N36S(TB)-V versus 4170Vrms for 4N36SM), maximum output voltage (80V versus 30V), turn-on/turn-off time (10µs/9µs versus 2µs/2µs), and operating temperature range (-55°C to 110°C versus -40°C to 100°C). All other parameters including CTR, forward voltage, saturation voltage, package type, and compliance status are equivalent.

Q: Are the PCB footprints identical?

A: Both parts use 6-SMD surface mount packages with gull wing leads. The physical footprints are identical, allowing direct PCB layout compatibility without redesign.

Q: What is the inventory status of these parts?

A: The 4N36S(TB)-V has 679 pieces in stock. The 4N36SM has 22,100 pieces in stock. Availability should be confirmed with the supplier for current project requirements.

Q: Do both parts have the same compliance certifications?

A: Both parts are ROHS3 compliant and have MSL Level 1 (Unlimited) moisture sensitivity rating. Both are classified as Active product status. The 4N36SM additionally has REACH Unaffected status.

Q: What is the base product number for the 4N36SM?

A: The base product number for the 4N36SM is 4N36, which is the generic optoisolator transistor series designation from onsemi.
