Engineering Selection Recommendations

PMT200EPEX (Nexperia USA Inc.)

The PMT200EPEX is the primary reference device with a 70V Vdss rating and 2.4A continuous drain current. This part is actively manufactured and maintains full RoHS3 compliance with MSL Level 1 rating. The device is suitable for applications requiring the specified voltage and current ratings within the -55°C to 150°C operating range.

NTF2955T1G (onsemi)

The NTF2955T1G is a P-Channel MOSFET with 60V Vdss and 1.7A continuous drain current. This substitute operates within a wider temperature range (-55°C to 175°C) and carries RoHS3 compliance with MSL Level 1 rating. The lower current rating (1.7A versus 2.4A) restricts this part to applications where the reduced current capacity is acceptable. The device is actively produced with 44,300 pieces in inventory.

NVF2955T1G (onsemi)

The NVF2955T1G is a P-Channel MOSFET with 60V Vdss and 2.6A continuous drain current, providing current capability that exceeds the main part specification. This substitute maintains RoHS3 compliance and MSL Level 1 rating with an extended operating temperature range (-55°C to 175°C). The device carries AEC-Q101 automotive qualification and is actively produced with 57,353 pieces in inventory. The higher current rating and automotive qualification make this part suitable for applications requiring enhanced performance margins or automotive-grade reliability.

All three devices share identical gate-source voltage limits (±20V), compatible package form factors (SOT-223), and surface mount mounting technology. Selection between these parts depends on specific application requirements for voltage rating, current capacity, and temperature range.

Frequently Asked Questions (FAQ)

Q: Can the NTF2955T1G replace the PMT200EPEX in all applications?

A: The NTF2955T1G has a lower continuous drain current rating (1.7A versus 2.4A). It can only replace the PMT200EPEX in applications where the circuit current requirement does not exceed 1.7A. The 60V Vdss rating is also lower than the 70V specification of the main part, limiting its use to circuits with maximum voltage stress below 60V.

Q: What are the key differences between NTF2955T1G and NVF2955T1G?

A: Both devices share the same 60V Vdss rating and P-Channel configuration. The primary differences are: (1) NTF2955T1G has 1.7A continuous drain current while NVF2955T1G provides 2.6A; (2) NVF2955T1G carries AEC-Q101 automotive qualification; (3) NTF2955T1G is supplied in Cut Tape & Digi-Reel® packaging while NVF2955T1G is supplied in Tape & Reel format.

Q: Are all three parts pin-compatible?

A: Yes. All three devices use the SOT-223 (TO-261-4, TO-261AA) package form factor with identical pin configurations for surface mount applications. Physical board layout and footprint requirements are identical.

Q: What is the impact of the lower Vdss rating on substitute parts?

A: Both substitute parts have a 60V Vdss rating compared to the main part's 70V specification. This means the substitute parts can only be used in circuits where the maximum drain-to-source voltage does not exceed 60V. Applications requiring the full 70V rating must use the PMT200EPEX or equivalent devices with 70V or higher Vdss ratings.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three devices are RoHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity ratings, and maintain active production status. The NVF2955T1G additionally carries AEC-Q101 automotive qualification, which is not required for the main part but provides enhanced reliability assurance for automotive applications.

Q: How do the on-state resistance values compare?

A: The PMT200EPEX has 167 mOhm Rds On at 2.4A and 10V gate-source voltage. The NTF2955T1G has 185 mOhm at the same conditions, representing approximately 11% higher resistance. The NVF2955T1G has 170 mOhm at 750mA and 10V, which is comparable to the main part but measured at a different current level. Higher Rds On values result in increased power dissipation during conduction.

Q: What is the significance of the extended temperature range in substitute parts?

A: Both substitute parts operate to 175°C junction temperature compared to the main part's 150°C maximum. This extended range provides additional thermal margin in applications operating at elevated ambient temperatures or with high power dissipation. However, the application circuit must be designed to accommodate this extended range if it is to be utilized.
