4N36SVM Equivalent & Substitute Parts

Part Overview

The 4N36SVM is an optoisolator transistor with base output manufactured by onsemi, rated for 4170Vrms isolation voltage in a 6-SMD surface mount package. This component provides galvanic isolation for single-channel DC input applications with transistor output capability. The 4N36SVM carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4N36SVM is determined by the following critical parameters:

• Isolation Voltage: 4170Vrms minimum
• Number of Channels: 1 channel
• Output Type: Transistor with Base
• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount
• Current Transfer Ratio (Min): 100% @ 10mA
• Vce Saturation (Max): 300mV
• Operating Temperature Range: -40°C ~ 100°C minimum

Parts meeting all these criteria are classified as direct equivalents. Parts with identical electrical specifications but different packaging formats are classified as direct manufacturer alternatives. Parts with variations in secondary parameters (such as isolation voltage specification format or current output rating) are classified as similar alternatives with noted deviations.

Engineering Selection Recommendations

4N36SM (Direct Equivalent - Recommended Primary Substitute)

The 4N36SM is the primary equivalent for the obsolete 4N36SVM. This part maintains identical electrical specifications across all critical parameters: 4170Vrms isolation voltage, 100% current transfer ratio at 10mA, 30V maximum output voltage, and 300mV maximum Vce saturation. The 4N36SM carries active product status from onsemi and holds ROHS3 compliance certification. Packaging is supplied in Tube format, suitable for standard component handling and assembly processes.

4N35SR2M (Similar Alternative)

The 4N35SR2M provides functional equivalence with identical core electrical specifications. This part is supplied by onsemi in active status with ROHS3 compliance. The primary distinction is packaging format (Cut Tape & Digi-Reel®), which may affect procurement and assembly workflows. All electrical parameters remain compatible with the original 4N36SVM specification.

4N36SMT&R (Similar Alternative - Limited Compatibility)

The 4N36SMT&R is manufactured by Isocom Components 2004 LTD and carries active product status with ROHS3 compliance. This part exhibits two parameter deviations: isolation voltage is specified as 7.5Vpk (versus 4170Vrms for the main part), and maximum DC forward current is rated at 50mA (versus 60mA). These deviations indicate this part is suitable only for applications where the lower isolation voltage specification and reduced forward current rating are acceptable. Packaging is supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 4N36SVM with 4N36SM in my existing design?

A: Yes. The 4N36SM maintains all critical electrical specifications of the 4N36SVM: 4170Vrms isolation, 100% CTR at 10mA, 30V output voltage, and 300mV Vce saturation. The primary difference is packaging format (Tube versus unspecified). Both parts use identical 6-SMD Gull Wing surface mount packages and operate across -40°C to 100°C.

Q: What is the difference between 4N36SM and 4N35SR2M?

A: Both parts are electrically identical and meet the same substitution criteria. The difference is packaging format: 4N36SM is supplied in Tube format, while 4N35SR2M is supplied in Cut Tape & Digi-Reel® format. Selection depends on your procurement and assembly process requirements.

Q: Is 4N36SMT&R a suitable replacement?

A: The 4N36SMT&R can function as a substitute only if your application tolerates two parameter variations: isolation voltage specified as 7.5Vpk (lower than the 4170Vrms specification) and maximum DC forward current of 50mA (versus 60mA). If your design requires the full 4170Vrms isolation or 60mA forward current capability, this part is not suitable.

Q: What does "active product status" mean for substitution purposes?

A: Active product status indicates the part is currently manufactured and available for procurement. The 4N36SVM is obsolete, meaning onsemi no longer manufactures it. The 4N36SM, 4N35SR2M, and 4N36SMT&R all carry active status, ensuring long-term availability and supply chain continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 4N36SM, 4N35SR2M, and 4N36SMT&R all carry ROHS3 compliance certification. The original 4N36SVM does not specify RoHS status in the provided data.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube, Cut Tape & Digi-Reel®, or Tape & Reel) affects only procurement, storage, and assembly handling. Electrical specifications and performance remain identical across all packaging options for equivalent parts.
