IRSF3010 Equivalent & Substitute Parts

Part Overview

The IRSF3010 is a Power Switch/Driver N-Channel component in TO-220AB packaging, rated for 11A maximum output current and 50V maximum load voltage. Manufactured by Infineon Technologies, this part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRSF3010 is determined by the following critical parameters:

• Package / Case: TO-220-3 (physical and thermal compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Output Configuration: Low Side switching capability
• Current Rating: Minimum 11A to meet or exceed original specification
• Voltage Rating: Minimum 50V load voltage capability
• Product Status: Active status preferred for supply chain continuity

The substitute parts identified (AVS08CB and AVS10CB) are thyristor-based components from STMicroelectronics. While these parts operate in different functional categories (TRIAC vs. Power Switch), they share the same TO-220-3 package and through-hole mounting configuration, enabling mechanical and thermal compatibility in applications where thyristor switching characteristics are acceptable.

Parameter Comparison

Engineering Selection Recommendations

AVS10CB is the preferred substitute based on the following criteria:

• Product Status: Active status ensures long-term supply availability and manufacturing continuity
• Current Capacity: 8A on-state current approaches the 11A requirement of the IRSF3010, providing closer performance matching
• Voltage Rating: 600V off-state voltage exceeds the 50V load voltage specification of the original part
• Compliance: ROHS3 compliant status aligns with modern regulatory requirements, whereas the IRSF3010 is RoHS non-compliant
• Package Compatibility: TO-220-3 package and through-hole mounting enable direct mechanical substitution

AVS08CB is a secondary alternative when current capacity constraints are acceptable:

• Product Status: Active status provides supply continuity
• Voltage Rating: 500V off-state voltage exceeds the 50V specification
• Compliance: ROHS3 compliant
• Limitation: 5A on-state current is below the 11A requirement and may not satisfy all application demands

Frequently Asked Questions (FAQ)

Q: Why are the substitute parts classified as thyristors rather than power switches?

A: The substitute parts (AVS08CB and AVS10CB) are TRIAC devices, which differ functionally from the IRSF3010 N-Channel power switch. However, they share identical TO-220-3 packaging and through-hole mounting, enabling mechanical and thermal compatibility. Application suitability depends on whether thyristor switching characteristics are compatible with the circuit design.

Q: Can AVS08CB be used if current capacity is a concern?

A: AVS08CB provides 5A on-state current, which is below the IRSF3010's 11A specification. Use of this part is limited to applications where load current does not exceed 5A. For applications requiring the full 11A capacity, AVS10CB is the more appropriate choice.

Q: What is the impact of the narrower operating temperature range in the substitute parts?

A: The IRSF3010 operates from -55°C to 150°C, while AVS08CB operates from -10°C to 125°C and AVS10CB from 0°C to 125°C. Applications requiring operation below -10°C or above 125°C cannot use these substitutes without thermal management modifications or alternative component selection.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both AVS08CB and AVS10CB are ROHS3 compliant, whereas the IRSF3010 is RoHS non-compliant. This compliance improvement may be advantageous for new designs or regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, from a mechanical and thermal perspective. Both substitute parts use the TO-220-3 package and through-hole mounting, allowing direct PCB footprint compatibility. However, functional circuit behavior will differ due to the thyristor switching characteristics versus the original power switch design.
