BTS134DNT Equivalent & Substitute Parts

Part Overview

The BTS134DNT is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, specifically a power switch/driver with 1:1 N-Channel configuration rated for 3.5A output current. This component operates as a low-side switch with general-purpose switching capability and includes integrated fault protection features including current limiting, over-temperature, and over-voltage protection.

The BTS134DNT is classified as obsolete. Finding equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS134DNT is determined by strict equivalence across the following critical parameters:

• Output Configuration & Type: Low-side N-channel switching topology
• Electrical Performance: 3.5A maximum output current, 35mOhm typical on-resistance, 42V maximum load voltage
• Functional Features: Auto restart capability, current limiting, over-temperature and over-voltage protection
• Interface & Control: Non-inverting on/off control logic
• Package Compatibility: TO-252-3 (DPAK) surface mount package
• Operating Range: -40°C to 150°C junction temperature rating
• Thermal & Environmental: MSL 1 rating, REACH compliance

The BTS134DATMA1 meets all these criteria as a parametric equivalent. It maintains identical electrical specifications, protection features, package form factor, and operating characteristics while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The BTS134DATMA1 is the direct parametric equivalent for the obsolete BTS134DNT. Both components share identical electrical specifications, protection architecture, and package form factor, ensuring drop-in compatibility at the circuit level.

Selection between these parts is determined by availability and regulatory requirements:

• BTS134DNT: Obsolete status limits new procurement. Existing inventory may be available through secondary markets but supply is finite.
• BTS134DATMA1: Active product status ensures ongoing availability and supply chain continuity. RoHS3 compliance certification provides additional regulatory assurance for new designs and production runs.

For new designs or ongoing production requiring this power switch topology, BTS134DATMA1 is the appropriate selection. For legacy system maintenance where original part numbers must be preserved, BTS134DNT may be sourced from remaining inventory channels.

Frequently Asked Questions (FAQ)

Q: Can BTS134DATMA1 replace BTS134DNT in existing designs?

A: Yes. BTS134DATMA1 is a parametric equivalent with identical electrical performance, protection features, and package specifications. No circuit modifications are required for substitution.

Q: Are there differences in pin configuration between these parts?

A: No. Both components use the TO-252-3 (DPAK) package with identical pin assignments and lead configuration.

Q: What is the significance of the product status difference?

A: BTS134DNT is classified as obsolete, meaning Infineon has discontinued production and support. BTS134DATMA1 maintains active status with ongoing manufacturing and availability. For new production or long-term supply requirements, BTS134DATMA1 is the recommended selection.

Q: Are there compliance or certification differences?

A: BTS134DATMA1 carries explicit RoHS3 compliance certification, while BTS134DNT does not specify this status. Both maintain REACH Unaffected classification and MSL 1 rating.

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

A: Yes. Identical package form factor, pin configuration, and electrical specifications enable direct substitution without PCB layout modifications or design changes.
