H11AA2SVM Optoisolator Equivalent & Substitute Parts

Part Overview

The H11AA2SVM is an optoisolator transistor with base output manufactured by onsemi, rated for 7500Vpk isolation voltage in a 6-SMD surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The H11AA2SVM serves applications requiring galvanic isolation with transistor output capability and AC/DC input compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the H11AA2SVM is determined by the following critical parameters:

• Isolation Voltage Rating: Minimum 7500Vpk or equivalent RMS rating
• Output Configuration: Transistor with base output
• Number of Channels: Single channel
• Package Type: 6-SMD, Gull Wing surface mount
• Input Type: AC/DC compatible
• Output Voltage Rating: Maximum 30V or higher
• Output Current: 50mA or greater per channel
• Vce Saturation: 400mV or lower
• Operating Temperature Range: Must encompass -40°C to 100°C minimum

Substitute parts are grouped based on isolation voltage equivalence and active product status where available. Parts with lower isolation ratings (4170Vrms, 5300Vrms) represent functional alternatives for applications not requiring the full 7500Vpk isolation specification. The H11AA2SM variant maintains identical electrical specifications but differs in packaging designation. Active alternatives from competing manufacturers (Vishay, Isocom) provide design flexibility with improved availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: H11AA2SM

The H11AA2SM is the direct equivalent to H11AA2SVM, maintaining identical electrical specifications and isolation voltage rating of 7500Vpk. Both parts are classified as obsolete; however, H11AA2SM maintains the same inventory availability (12300 pcs). This part is suitable for direct replacement in existing designs without circuit modification.

Active Alternatives with Full Isolation Rating:

No active onsemi parts maintain the 7500Vpk isolation specification. The H11AA2SMT&R from Isocom Components is listed with 7.5Vpk isolation, which does not meet the isolation voltage requirement and is not suitable as a substitute.

Active Alternatives with Reduced Isolation Rating:

• H11AA1SVM (onsemi): Active product with 4170Vrms isolation. Suitable for applications where 7500Vpk isolation is not required. Current transfer ratio improved to 20% @ 10mA. Identical output specifications (30V, 50mA).

• H11AA1-X007T (Vishay Semiconductor Opto Division): Active product with 5300Vrms isolation. Extended operating temperature range (-55°C to 100°C). Tape & Reel packaging. Current transfer ratio 20% @ 10mA. Output current specification not provided.

• IL252-X007T (Vishay Semiconductor Opto Division): Active product with 5300Vrms isolation. Superior current transfer ratio of 100% @ 10mA. Extended operating temperature range (-55°C to 100°C). Tape & Reel packaging. Output current specification not provided.

Compliance Status:

H11AA1SVM, H11AA1-X007T, H11AA2SMT&R, and IL252-X007T are RoHS3 compliant. All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can H11AA1SVM replace H11AA2SVM in all applications?

A: H11AA1SVM is suitable only for applications where the isolation voltage requirement is 4170Vrms or lower. If your circuit design requires 7500Vpk isolation, H11AA1SVM is not an appropriate substitute. Verify isolation voltage requirements in your application specifications before substitution.

Q: What is the difference between H11AA2SVM and H11AA2SM?

A: H11AA2SVM and H11AA2SM are electrically identical with matching isolation voltage (7500Vpk), output specifications, and operating temperature range. The difference is in packaging designation only. Both parts are obsolete with equivalent inventory availability.

Q: Are Vishay IL252-X007T and H11AA1-X007T interchangeable?

A: Both parts share identical isolation voltage (5300Vrms), package type (6-SMD, Gull Wing), and operating temperature range (-55°C to 100°C). However, IL252-X007T offers superior current transfer ratio (100% @ 10mA versus 20% @ 10mA). Output current specifications differ: H11AA1-X007T does not specify output current, while IL252-X007T also does not specify this parameter. Consult manufacturer datasheets for complete electrical characteristics before substitution.

Q: Why is H11AA2SMT&R not recommended as a substitute?

A: H11AA2SMT&R specifies isolation voltage as 7.5Vpk, which is significantly lower than the H11AA2SVM requirement of 7500Vpk. This part does not meet the isolation voltage specification and is not suitable for direct substitution.

Q: What packaging options are available for active substitutes?

A: H11AA1SVM is available in Bulk packaging. H11AA1-X007T, H11AA2SMT&R, and IL252-X007T are available in Tape & Reel (TR) packaging. All maintain the 6-SMD, Gull Wing surface mount configuration compatible with H11AA2SVM PCB layouts.

Q: Do all substitute parts support AC and DC input?

A: Yes. All listed substitute parts (H11AA1SVM, H11AA1-X007T, H11AA2SM, H11AA2SMT&R, IL252-X007T) support both AC and DC input types, matching the H11AA2SVM input compatibility.
