H11F13S Equivalent & Substitute Parts

Part Overview

The H11F13S is an optoisolator with MOSFET output manufactured by onsemi, designed for high-voltage isolation applications. It provides 5300Vrms isolation voltage in a 6-SMD surface mount package. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11F13S is determined by the following critical parameters:

• Isolation Voltage: The substitute must maintain isolation voltage at or above the application requirement. The H11F13S provides 5300Vrms isolation.
• Output Type: MOSFET output configuration must be preserved for circuit compatibility.
• Number of Channels: Single-channel configuration must be maintained.
• Package / Case: 6-SMD, Gull Wing surface mount package ensures PCB compatibility.
• Input Type: DC input type must be consistent.
• Maximum Output Voltage: 30V maximum output voltage specification must be met.
• Forward Voltage and Current: Input characteristics (Vf = 1.3V, If = 60 mA max) define LED drive requirements.

The H11F1SM is grouped as a substitute based on matching output type (MOSFET), channel count (1), package configuration (6-SMD, Gull Wing), input type (DC), and maximum output voltage (30V). However, the isolation voltage is lower at 4170Vrms, and switching speed is reduced. This substitute is suitable only for applications where the lower isolation voltage is acceptable.

Engineering Selection Recommendations

The H11F1SM is the designated substitute for the obsolete H11F13S within the onsemi H11F product family. Selection between these parts must be based on isolation voltage requirements:

• H11F13S: Use only if existing inventory is available or if the application specifically requires 5300Vrms isolation voltage and -55°C minimum operating temperature.
• H11F1SM: Recommended for new designs and ongoing procurement. This part is active and in production. It is RoHS3 compliant, whereas the H11F13S compliance status is not specified. The H11F1SM is suitable for applications requiring 4170Vrms isolation or higher, with operating temperature range of -40°C to 100°C.

Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming regulatory equivalence for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can H11F1SM directly replace H11F13S in all applications?

A: Direct replacement is possible only if the application isolation voltage requirement is 4170Vrms or lower. The H11F13S provides higher isolation voltage (5300Vrms). If the circuit design requires 5300Vrms isolation, H11F1SM is not suitable.

Q: What are the switching speed differences between these parts?

A: The H11F13S has a turn-on/turn-off time of 25µs (maximum), while the H11F1SM has 45µs (maximum). Applications with timing-critical switching requirements must account for this 20µs difference in propagation delay.

Q: Are the package dimensions identical?

A: Both parts use 6-SMD, Gull Wing surface mount packages. PCB footprints are compatible, and no layout modifications are required for mechanical substitution.

Q: What is the operating temperature difference?

A: The H11F13S operates from -55°C to 100°C, while the H11F1SM operates from -40°C to 100°C. Applications requiring operation below -40°C cannot use the H11F1SM substitute.

Q: Is the H11F1SM RoHS compliant?

A: Yes, the H11F1SM is RoHS3 compliant. The H11F13S compliance status is not specified in the provided data.

Q: Are input and output electrical characteristics identical?

A: Input characteristics are identical: Vf = 1.3V typical, If = 60 mA maximum. Output characteristics are identical: 30V maximum output voltage, MOSFET output type, single channel. Both parts accept DC input signals.
