H11AV2FM Optoisolator Equivalent & Substitute Parts

Part Overview

The H11AV2FM is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 7500Vpk isolation rating. This component features a single-channel configuration with transistor output and integrated base connection, suitable for DC input applications. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H11AV2FM is determined by the following critical parameters:

• Number of Channels: Must be 1 (single-channel configuration)
• Output Type: Must be Transistor with Base
• Voltage - Isolation: Minimum 5300Vrms or equivalent peak voltage rating
• Current Transfer Ratio (Min): Must meet or exceed 50% @ 10mA
• Vce Saturation (Max): Must not exceed 400mV
• Voltage - Output (Max): Must support minimum 70V
• Input Type: Must be DC

The H11AV2X qualifies as a functional substitute based on these parameters, though with noted differences in isolation voltage specification format (5300Vrms versus 7500Vpk) and package configuration (6-DIP through-hole versus 6-SMD surface mount).

Parameter Comparison

Engineering Selection Recommendations

The H11AV2X represents an active-status alternative to the obsolete H11AV2FM. Both components share identical current transfer ratio specifications and maximum saturation voltage characteristics, establishing functional equivalence for DC-input optoisolation applications.

Key considerations for component selection:

Isolation Voltage: The H11AV2FM specifies 7500Vpk isolation, while the H11AV2X specifies 5300Vrms isolation. These represent different measurement standards; direct numerical comparison requires conversion between peak and RMS values. Applications requiring the full 7500Vpk specification may require isolation voltage verification before substitution.

Package Configuration: The H11AV2FM uses surface-mount technology (6-SMD, Gull Wing), while the H11AV2X uses through-hole technology (6-DIP). This difference necessitates PCB redesign and assembly process modification.

Operating Temperature: The H11AV2X supports an extended lower temperature range (-55°C versus -40°C), providing broader environmental compatibility.

Compliance Status: The H11AV2X carries ROHS3 compliance certification, while the H11AV2FM status is not specified in provided data.

Frequently Asked Questions (FAQ)

Q: Can H11AV2X directly replace H11AV2FM on existing PCBs?

A: No. The H11AV2FM uses 6-SMD surface-mount packaging while the H11AV2X uses 6-DIP through-hole packaging. PCB layout and assembly process modifications are required.

Q: Are the isolation voltage ratings equivalent?

A: The specifications use different measurement standards (7500Vpk versus 5300Vrms). Numerical comparison requires conversion between peak and RMS voltage values. Applications with specific isolation voltage requirements should confirm compatibility with the H11AV2X rating.

Q: What are the matching electrical characteristics?

A: Both components share identical current transfer ratio minimums (50% @ 10mA), maximum Vce saturation (400mV), maximum output voltage (70V), and maximum forward current (60mA). These parameters establish functional equivalence for DC-input optoisolation circuits.

Q: Does the H11AV2X support the same operating temperature range?

A: The H11AV2X supports -55°C to 100°C, which extends below the H11AV2FM range of -40°C to 100°C. Applications operating at temperatures between -55°C and -40°C benefit from the H11AV2X extended range.

Q: What compliance certifications apply to each component?

A: The H11AV2X carries ROHS3 compliance certification. Both components are REACH Unaffected and classified under ECCN EAR99.
