IR3310STRR Equivalent & Substitute Parts

Part Overview

The IR3310STRR is a Power Switch/Driver IC featuring 1:1 N-Channel configuration with 23A maximum output current in D2PAK (SMD-220 5-Lead) surface mount packaging. This component functions as a high-side N-channel power switch with on/off interface control, designed for load voltage applications ranging from 6V to 28V. The IR3310STRR is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR3310STRR is determined by the following critical parameters:

Mechanical Compatibility: Package type must be TO-263-5 (D2PAK) to ensure direct pin-compatible replacement without PCB redesign.

Electrical Compatibility: The substitute must maintain 1:1 input-to-output ratio with high-side N-channel output configuration and on/off interface control. Operating temperature range must encompass -40°C to 150°C (TJ).

Functional Compatibility: The substitute must support general-purpose power switching with non-inverting input logic. Load voltage operating range and maximum output current capacity determine application suitability.

Regulatory Compliance: Modern substitutes should meet current RoHS and REACH compliance standards to support contemporary manufacturing and supply chain requirements.

The BTS441RGATMA1 qualifies as a substitute based on matching package type, output configuration, interface type, and operating temperature range, while offering enhanced fault protection features and active product status.

Parameter Comparison

Engineering Selection Recommendations

The BTS441RGATMA1 serves as the primary substitute for the obsolete IR3310STRR based on the following engineering criteria:

Package Compatibility: Both components utilize TO-263-5 (D2PAK) surface mount packaging, enabling direct PCB placement without layout modifications.

Electrical Equivalence: Both devices feature 1:1 input-to-output ratio, high-side N-channel output configuration, non-inverting input logic, and identical operating temperature range (-40°C to 150°C TJ).

Load Voltage Coverage: The BTS441RGATMA1 supports an extended load voltage range (4.75V to 43V) compared to the IR3310STRR (6V to 28V), providing broader application compatibility.

Current Rating Consideration: The BTS441RGATMA1 provides 17A maximum output current versus the IR3310STRR's 23A. Applications requiring the full 23A capacity must evaluate thermal and current distribution requirements.

Compliance Status: The BTS441RGATMA1 holds active product status and ROHS3 compliance, supporting modern manufacturing standards and supply chain continuity. The IR3310STRR's obsolete status and RoHS non-compliance status necessitate transition planning.

Enhanced Protection Features: The BTS441RGATMA1 includes status flag output, open load detection, and over-voltage protection beyond the IR3310STRR's current limiting and over-temperature protection.

Frequently Asked Questions (FAQ)

Q: Can the BTS441RGATMA1 directly replace the IR3310STRR without PCB modifications?

A: Yes. Both components share identical TO-263-5 (D2PAK) packaging with matching pin configurations, enabling direct substitution without PCB redesign.

Q: What is the impact of the 6A current rating difference between these components?

A: The BTS441RGATMA1 provides 17A maximum output current compared to the IR3310STRR's 23A. Applications operating below 17A experience no functional impact. Designs requiring sustained currents above 17A must implement parallel switching configurations or alternative topologies.

Q: Does the BTS441RGATMA1's higher Rds On (15mOhm vs 5.5mOhm) affect thermal performance?

A: Higher on-resistance increases power dissipation at equivalent current levels. Thermal analysis must account for the increased I²R losses. Applications with marginal thermal budgets may require enhanced heat sinking or current derating.

Q: Are the fault protection features of the BTS441RGATMA1 compatible with existing control circuits?

A: The BTS441RGATMA1 maintains on/off interface compatibility with the IR3310STRR. Enhanced protection features (status flag, open load detect, over-voltage) operate independently and do not interfere with legacy control implementations. Status flag outputs may be left unconnected in designs not requiring this functionality.

Q: What compliance advantages does the BTS441RGATMA1 provide?

A: The BTS441RGATMA1 meets ROHS3 compliance and maintains active product status, ensuring long-term supply availability and compatibility with current manufacturing regulations. The IR3310STRR's obsolete status and RoHS non-compliance create supply chain risk and regulatory exposure.

Q: Is the extended load voltage range (4.75V to 43V) of the BTS441RGATMA1 a concern for existing designs?

A: No. The extended range provides additional design flexibility without affecting applications within the original IR3310STRR specification (6V to 28V). Existing designs operate identically within their original voltage envelope.
