IR3312STRL Equivalent & Substitute Parts

Part Overview

The IR3312STRL is a Power Switch/Driver IC manufactured by Infineon Technologies, designed for high-side N-channel switching applications. This component operates as a 1:1 power switch with a maximum output current of 14A and an on-resistance (RDS On) of 15mOhm typical. The device is packaged in D2PAK (TO-263-5) surface mount configuration and supports load voltages ranging from 6V to 28V.

The IR3312STRL has reached obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the original electrical specifications, mechanical packaging, and thermal characteristics to ensure seamless integration into existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IR3312STRL must satisfy the following critical parameters to ensure functional equivalence:

Electrical Compatibility Requirements:

• Output configuration: High Side N-Channel
• Ratio: 1:1 (single output)
• Interface: On/Off control
• Input type: Non-Inverting
• RDS On (Typ): 15mOhm (matching on-resistance)
• Fault protection: Current limiting and over-temperature protection minimum

Mechanical & Thermal Requirements:

• Mounting type: Surface Mount
• Package: TO-263-5 / D2PAK compatible
• Operating temperature range: -40°C ~ 150°C (TJ) minimum

Voltage & Current Specifications:

• Load voltage range must encompass or exceed 6V ~ 28V
• Output current rating must meet or exceed 14A

The BTS441TGATMA1 meets all substitution criteria. It maintains identical electrical architecture (1:1 high-side N-channel), equivalent on-resistance (15mOhm typical), compatible packaging (TO-263-5), and matching thermal operating range. The substitute provides enhanced specifications in load voltage range (4.75V ~ 43V) and output current (17A), offering improved performance margins for the original application.

Parameter Comparison

Engineering Selection Recommendations

The BTS441TGATMA1 is the qualified substitute for the obsolete IR3312STRL. Both components are manufactured by Infineon Technologies and share identical electrical architecture and packaging specifications.

Product Status Advantage: The BTS441TGATMA1 maintains Active product status, ensuring long-term availability and continued manufacturer support. The IR3312STRL's Obsolete status creates supply chain risk and limits access to technical documentation updates.

Compliance Improvement: The BTS441TGATMA1 achieves ROHS3 compliance, whereas the IR3312STRL is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in most markets.

Performance Enhancement: The substitute provides superior electrical specifications within the same package footprint. The expanded load voltage range (4.75V ~ 43V versus 6V ~ 28V) and increased current rating (17A versus 14A) deliver improved operational margins without requiring circuit redesign.

Fault Protection Enhancement: The BTS441TGATMA1 includes over-voltage protection in addition to current limiting and over-temperature protection, providing enhanced system reliability compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the BTS441TGATMA1 directly replace the IR3312STRL without circuit modifications?

A: Yes. Both components share identical electrical specifications for the critical parameters: 1:1 high-side N-channel configuration, 15mOhm on-resistance, On/Off interface, and TO-263-5 packaging. The substitute operates within the same thermal range (-40°C ~ 150°C TJ) and maintains equivalent fault protection functionality. No circuit redesign is required.

Q: What are the key differences between these two parts?

A: The primary differences are product status and compliance. The BTS441TGATMA1 is an Active product with ROHS3 compliance, while the IR3312STRL is Obsolete and RoHS non-compliant. The substitute also provides enhanced specifications: wider load voltage range (4.75V ~ 43V versus 6V ~ 28V), higher current rating (17A versus 14A), and additional over-voltage protection.

Q: Are the packages mechanically identical?

A: Yes. Both components use the TO-263-5 / D2PAK surface mount package with identical pinout and lead configuration. PCB layout and thermal management designs require no modification.

Q: Does the BTS441TGATMA1 require different handling or storage conditions?

A: No. Both parts share identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What is the impact of the current limiting change from Adjustable to Fixed?

A: The IR3312STRL features adjustable current limiting, while the BTS441TGATMA1 implements fixed current limiting. For applications requiring adjustable current limiting, external circuit modifications may be necessary. For standard on/off switching applications, fixed current limiting provides equivalent protection.

Q: Is the BTS441TGATMA1 available in the same packaging format?

A: The BTS441TGATMA1 is supplied in Tape & Reel (TR) format, which is standard for production environments. The IR3312STRL packaging format was not specified in the original documentation. Both use identical TO-263-5 component packaging suitable for automated assembly.
