IRSF3011 Equivalent & Substitute Parts

Part Overview

The IRSF3011 is a Power Switch/Driver IC featuring 1:1 N-Channel configuration with 5A maximum output current in TO-220AB packaging. Manufactured by Infineon Technologies, this component functions as a general-purpose low-side driver with on/off interface control. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar switching capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IRSF3011 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Package compatibility: TO-220-3 through-hole mounting
• Output current capability: Minimum 5A rating
• Voltage handling: Load voltage rating of 50V or greater
• Operating temperature range: Support for industrial temperature requirements
• Switching functionality: General-purpose switching or thyristor-based control

The identified substitutes (AVS08CB and AVS10CB) are thyristor-based components from STMicroelectronics that provide equivalent switching capability in the same physical package. Both parts maintain TO-220-3 packaging and exceed the 5A current requirement of the original IRSF3011.

Parameter Comparison

Engineering Selection Recommendations

AVS08CB Selection Criteria: The AVS08CB provides direct current-level equivalence at 5A maximum on-state current. This part is suitable for applications where the 50V load voltage of the IRSF3011 is the primary design constraint. The AVS08CB's 500V off-state voltage rating provides substantial margin above the original specification. Active product status and ROHS3 compliance support long-term availability and regulatory alignment for new designs.

AVS10CB Selection Criteria: The AVS10CB offers enhanced current capability at 8A maximum on-state current, providing design margin for applications requiring higher switching capacity. The 600V off-state voltage rating exceeds both the original IRSF3011 and AVS08CB specifications. Active product status and ROHS3 compliance ensure supply continuity. The operating temperature range (0°C ~ 125°C) is narrower than the IRSF3011 but suitable for standard industrial applications.

Compliance Considerations: Both substitute parts achieve ROHS3 compliance, addressing regulatory requirements that the obsolete IRSF3011 does not meet. Both parts maintain unlimited moisture sensitivity level (MSL 1), matching the original component's handling requirements.

Frequently Asked Questions (FAQ)

Q: Why is the IRSF3011 being replaced? A: The IRSF3011 is classified as obsolete by the manufacturer. Substitute parts ensure continued system support and enable new designs using actively manufactured components with improved regulatory compliance.

Q: Are AVS08CB and AVS10CB pin-compatible with IRSF3011? A: Both substitute parts use TO-220-3 packaging, providing identical physical pin configuration and through-hole mounting compatibility with the original IRSF3011.

Q: What is the functional difference between AVS08CB and AVS10CB? A: The primary differences are current rating (5A vs. 8A) and voltage rating (500V vs. 600V). AVS08CB matches the original 5A specification, while AVS10CB provides higher current capacity. Both are thyristor-based internally triggered devices.

Q: Do the substitute parts have the same fault protection as IRSF3011? A: The provided specifications for AVS08CB and AVS10CB do not detail over-temperature or over-voltage protection features. Circuit-level design review is necessary to confirm equivalent protection implementation.

Q: What is the operating temperature impact of substitution? A: The IRSF3011 operates from -55°C to 150°C. AVS08CB operates from -10°C to 125°C, and AVS10CB from 0°C to 125°C. Applications requiring extended low-temperature operation below -10°C require design verification.

Q: Are both substitutes suitable for new designs? A: Yes. Both AVS08CB and AVS10CB are active products with ROHS3 compliance, supporting long-term supply availability and regulatory requirements for new designs.
