H11N13SD Equivalent & Substitute Parts

Part Overview

The H11N13SD is a logic output optoisolator manufactured by onsemi, designed for applications requiring galvanic isolation with open collector output configuration. This component features 7500Vrms isolation voltage, 5MHz data rate capability, and 6-SMD surface mount packaging. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11N13SD is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Single channel configuration (1 channel)
• DC input type
• Open collector output type
• 50 mA output current per channel
• 5MHz data rate
• 330ns maximum propagation delay (both tpLH and tpHL)
• 6-SMD, Gull Wing surface mount package
• 1.4V typical forward voltage

Isolation Voltage Consideration: The H11N13SD specifies 7500Vrms isolation voltage. Substitute parts with lower isolation ratings (such as 4170Vrms) may be used in applications where the full isolation specification is not required, provided system design margins and safety standards permit.

Forward Current Tolerance: The H11N13SD maximum DC forward current is 3.2mA. Substitute parts with higher forward current ratings (such as 30mA) provide additional design margin and are directly compatible.

Engineering Selection Recommendations

H11N1SVM as Primary Substitute:

The H11N1SVM is the direct manufacturer-designated substitute for the H11N13SD. All critical functional parameters align: single channel, DC input, open collector output, 50mA output current, 5MHz data rate, and 330ns propagation delay specifications are identical. Both components use the same 6-SMD, Gull Wing package.

Product Status Advantage: The H11N1SVM holds active product status with ROHS3 compliance, whereas the H11N13SD is obsolete and RoHS non-compliant. For new designs and long-term system support, the H11N1SVM provides supply continuity and regulatory alignment.

Isolation Voltage Consideration: The H11N1SVM specifies 4170Vrms isolation compared to the H11N13SD's 7500Vrms. Applications requiring the full 7500Vrms isolation specification must evaluate whether the reduced isolation of the substitute meets system safety and regulatory requirements. In applications where 4170Vrms isolation is sufficient, the H11N1SVM is fully compatible.

Forward Current Margin: The H11N1SVM maximum DC forward current rating of 30mA exceeds the H11N13SD specification of 3.2mA, providing additional design margin for input drive circuits.

Frequently Asked Questions (FAQ)

Q: Can the H11N1SVM directly replace the H11N13SD in existing designs?

A: The H11N1SVM is functionally compatible for all critical parameters: channel count, input/output types, output current, data rate, and propagation delay. However, the reduced isolation voltage (4170Vrms vs. 7500Vrms) must be evaluated against system requirements. If the original design requires 7500Vrms isolation, alternative parts with higher isolation ratings should be considered.

Q: What are the key differences between these parts?

A: The primary differences are isolation voltage (7500Vrms vs. 4170Vrms), forward current rating (3.2mA vs. 30mA), product status (obsolete vs. active), and RoHS compliance. Functional performance parameters including data rate, propagation delay, and output current are identical.

Q: Is the 6-SMD package identical between both parts?

A: Both the H11N13SD and H11N1SVM use 6-SMD, Gull Wing surface mount packaging. PCB footprints and assembly processes are compatible.

Q: Why is the H11N13SD obsolete?

A: The H11N13SD is classified as obsolete by the manufacturer. The H11N1SVM represents the active product line continuation with improved specifications and regulatory compliance.

Q: What supply voltage does the H11N1SVM require?

A: The H11N1SVM operates with supply voltage from 4V to 15V. The H11N13SD datasheet does not specify supply voltage requirements; verify compatibility with your system design.

Q: Are there any thermal or operating temperature differences?

A: The H11N1SVM specifies operating temperature range of -40°C to 85°C. The H11N13SD datasheet does not provide operating temperature specifications. Confirm temperature requirements for your application.
