NVGS3441T1G P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The NVGS3441T1G is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 1.65A continuous drain current at 25°C. The device is packaged in a 6-TSOP surface mount configuration and is qualified to AEC-Q101 automotive standards. This part is currently classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility across voltage ratings, current handling capability, thermal characteristics, and package form factor while meeting automotive qualification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NVGS3441T1G is determined by the following critical parameters that must be maintained or exceeded:

Voltage Rating: All substitute parts must maintain the 20V Vdss rating to ensure safe operation within the same voltage domain.

Current Capability: Substitute parts must support the 1.65A continuous drain current requirement at 25°C ambient temperature. Parts with higher current ratings provide design margin and are acceptable substitutes.

Package Compatibility: The 6-TSOP surface mount package form factor must be preserved to maintain PCB layout compatibility and assembly process alignment.

Thermal Operating Range: All substitute parts must support the -55°C to 150°C junction temperature range required for automotive applications.

Automotive Qualification: Substitute parts must carry automotive-grade qualification (AEC-Q100 or AEC-Q101) to meet production and reliability standards.

RoHS and Environmental Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status.

The two substitute parts identified (PMN48XPAX and PMN70XPEAX) satisfy these criteria while offering enhanced performance characteristics in current handling and gate charge specifications.

Parameter Comparison

Engineering Selection Recommendations

PMN48XPAX (Nexperia USA Inc.): This substitute part exceeds the current requirement of the NVGS3441T1G with a 4.1A continuous drain current rating. The device maintains the 20V voltage specification and operates across the identical -55°C to 150°C temperature range. PMN48XPAX carries AEC-Q100 automotive qualification and ROHS3 compliance. The lower on-resistance (55mOhm) and reduced gate charge (13 nC) provide improved switching efficiency. Package compatibility is maintained in the 6-TSOP form factor. This part is currently in active production status.

PMN70XPEAX (Nexperia USA Inc.): This substitute part provides 3.2A continuous drain current, exceeding the 1.65A requirement of the NVGS3441T1G. The 20V voltage rating and -55°C to 150°C operating temperature range are maintained. PMN70XPEAX carries automotive-grade qualification and ROHS3 compliance. The significantly reduced gate charge (7.8 nC) offers advantages in switching speed and gate drive requirements. The on-resistance specification (85mOhm) is comparable to the original part. Package compatibility is maintained in the 6-TSOP form factor. This part is currently in active production status.

Both substitute parts address the obsolescence of the NVGS3441T1G while providing enhanced electrical performance and active manufacturing support from qualified automotive suppliers.

Frequently Asked Questions (FAQ)

Q: Can PMN48XPAX or PMN70XPEAX be used as direct replacements for NVGS3441T1G?

A: Both parts satisfy the core substitution criteria: identical 20V Vdss rating, current capability exceeding 1.65A, matching -55°C to 150°C operating temperature range, automotive-grade qualification, ROHS3 compliance, and 6-TSOP surface mount packaging. Direct PCB substitution is supported without layout modification.

Q: What is the difference between PMN48XPAX and PMN70XPEAX?

A: PMN48XPAX provides 4.1A continuous drain current with 55mOhm on-resistance and 13 nC gate charge. PMN70XPEAX provides 3.2A continuous drain current with 85mOhm on-resistance and 7.8 nC gate charge. PMN70XPEAX offers lower gate charge for faster switching response, while PMN48XPAX offers higher current capacity and lower on-resistance for reduced power dissipation.

Q: Are the package designations SOT-23-6 and SC-74/SOT-457 compatible?

A: Both designations refer to the same 6-pin TSOP surface mount package form factor. The parts are physically and electrically compatible for PCB assembly without modification.

Q: What automotive qualifications do the substitute parts carry?

A: PMN48XPAX carries AEC-Q100 qualification. PMN70XPEAX carries automotive-grade designation. Both parts meet automotive reliability and quality standards required for production applications.

Q: Are there differences in gate charge that affect circuit design?

A: PMN70XPEAX has significantly lower gate charge (7.8 nC) compared to NVGS3441T1G (14 nC) and PMN48XPAX (13 nC). Lower gate charge reduces gate drive power requirements and enables faster switching transitions. Circuit designs with tight gate drive timing specifications should account for this parameter difference.

Q: Do all substitute parts maintain the same moisture sensitivity level?

A: Yes. NVGS3441T1G, PMN48XPAX, and PMN70XPEAX all carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
