H11AV2VM Optoisolator Equivalent & Substitute Parts

Part Overview

The H11AV2VM is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications. This component features a 7500Vpk isolation rating and operates as a 1-channel optoisolator in a 6-DIP through-hole package. 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

Substitute parts for the H11AV2VM are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Single-channel optoisolator configuration
• Transistor with base output topology
• 6-DIP through-hole package format (0.300", 7.62mm)
• Minimum 50% current transfer ratio at 10mA
• Maximum output voltage of 70V
• Vce saturation maximum of 400mV
• DC forward current maximum of 60mA
• Input type: DC

Secondary Compatibility Considerations:

• Isolation voltage rating (minimum acceptable threshold for application)
• Operating temperature range
• Forward voltage characteristics
• Rise and fall time specifications

The H11AV2X qualifies as a substitute based on matching the primary compatibility criteria, though with a lower isolation voltage rating (5300Vrms versus 7500Vpk).

Engineering Selection Recommendations

H11AV2X as Substitute:

The H11AV2X is available as an active product from Isocom Components 2004 LTD, providing supply continuity for applications currently using the obsolete H11AV2VM. Both parts share identical package geometry, output topology, and core electrical characteristics including current transfer ratio, output voltage rating, and saturation voltage.

The primary difference is the isolation voltage specification: the H11AV2X provides 5300Vrms isolation compared to the H11AV2VM's 7500Vpk isolation. Applications requiring the full 7500Vpk isolation rating must evaluate whether the lower isolation voltage of the substitute is acceptable for their specific circuit requirements.

The H11AV2X offers ROHS3 compliance and an extended lower operating temperature limit (-55°C versus -40°C), providing additional environmental flexibility. The specified rise and fall times of 2µs for the H11AV2X support timing-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the H11AV2X directly replace the H11AV2VM in existing designs?

A: Physical and functional compatibility is confirmed for package format, pin configuration, output topology, and primary electrical parameters. However, the isolation voltage difference (5300Vrms versus 7500Vpk) must be evaluated against your application's isolation requirements before substitution.

Q: What is the difference between Vpk and Vrms isolation ratings?

A: Both measurements specify isolation voltage capability. The H11AV2VM specifies 7500Vpk (peak voltage), while the H11AV2X specifies 5300Vrms (root mean square voltage). These represent different measurement standards for the same isolation parameter.

Q: Are the 6-DIP packages identical between both parts?

A: Yes. Both the H11AV2VM and H11AV2X use the same 6-DIP package format with 0.300" (7.62mm) spacing, ensuring identical PCB footprint and through-hole mounting compatibility.

Q: Does the H11AV2X meet RoHS requirements?

A: The H11AV2X is ROHS3 compliant. RoHS compliance status for the H11AV2VM is not specified in the available documentation.

Q: What are the timing differences between these parts?

A: The H11AV2VM specifies 15µs turn-on and turn-off times. The H11AV2X specifies 2µs rise and fall times, indicating faster switching response. The H11AV2VM's turn-on/turn-off specification is not directly comparable to rise/fall time measurements.

Q: Is the H11AV2X suitable for low-temperature applications?

A: The H11AV2X operates from -55°C to 100°C, extending the lower temperature limit compared to the H11AV2VM's -40°C to 100°C range, making it suitable for expanded environmental conditions.
