MTP3055V N-Channel 60V 12A MOSFET Equivalent & Substitute Parts

Part Overview

The MTP3055V is an N-Channel MOSFET manufactured by onsemi, rated for 60V drain-to-source voltage and 12A continuous drain current at 25°C. The device is housed in a TO-220AB through-hole package and is designed for general-purpose switching applications requiring moderate current handling at 60V operation.

The MTP3055V is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute devices must maintain electrical compatibility across critical parameters including voltage rating, current capacity, on-resistance characteristics, and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the MTP3055VL be used as a direct replacement for the MTP3055V?

A: Yes. The MTP3055VL is electrically and mechanically equivalent to the MTP3055V. Both devices share identical 60V Vdss rating, 12A continuous drain current, TO-220-3 package configuration, and 48W power dissipation. The MTP3055VL is active product status with ROHS3 compliance, making it the preferred direct substitute.

Q: What is the difference between the MTP3055V and STP16NF06?

A: The STP16NF06 provides 16A continuous drain current compared to the MTP3055V's 12A rating, representing a 33% current increase. The STP16NF06 features lower on-resistance (100mOhm vs. 150mOhm) and reduced gate charge (13nC vs. 17nC). Both devices maintain 60V Vdss rating and TO-220-3 package. The STP16NF06 is active product status with ROHS3 compliance.

Q: When should I use the STP36NF06L instead of the MTP3055V?

A: The STP36NF06L is appropriate for applications requiring higher current capacity (30A vs. 12A) or reduced power dissipation. The STP36NF06L features significantly lower on-resistance (40mOhm vs. 150mOhm) and higher power dissipation capability (70W vs. 48W). Both devices maintain 60V Vdss rating and TO-220-3 package. The STP36NF06L is active product status with ROHS3 compliance.

Q: Are the PSMN4R6-60PS,127 and PSMN3R0-60PS,127 suitable replacements for the MTP3055V?

A: These devices are not recommended as direct replacements. While both maintain 60V Vdss rating and TO-220-3 package, they are rated for 100A continuous drain current, significantly exceeding the MTP3055V's 12A specification. Both devices are classified as obsolete product status. These parts are suitable only for applications requiring extreme current capacity where the elevated gate charge and input capacitance are acceptable.

Q: What is the impact of on-resistance differences between substitute parts?

A: On-resistance directly affects power dissipation and switching efficiency. Lower on-resistance values reduce conduction losses. The MTP3055V features 150mOhm on-resistance, while the STP16NF06 provides 100mOhm and the STP36NF06L provides 40mOhm. Selection depends on thermal budget and efficiency requirements. Higher current-rated devices typically feature lower on-resistance values.

Q: Are all substitute parts ROHS3 compliant?

A: The MTP3055V is RoHS non-compliant. All recommended substitute parts (MTP3055VL, STP16NF06, STP36NF06L) are ROHS3 compliant. The higher-performance alternatives (PSMN4R6-60PS,127 and PSMN3R0-60PS,127) are also ROHS3 compliant. ROHS3 compliance is required for new designs and applications subject to environmental regulations.

Q: What is the significance of gate charge differences?

A: Gate charge (Qg) affects switching speed and drive circuit requirements. Lower gate charge values enable faster switching transitions and reduce driver power consumption. The MTP3055V features 17nC gate charge at 10V. The MTP3055VL features 10nC at 5V, the STP16NF06 features 13nC at 10V, and the STP36NF06L features 17nC at 5V. Selection depends on switching frequency requirements and driver circuit capabilities.

Q: Can I use a higher-rated current device in place of the MTP3055V?

A: Yes, provided all other electrical parameters remain compatible. Devices with higher current ratings (STP16NF06 at 16A, STP36NF06L at 30A) can be used in applications designed for the MTP3055V's 12A rating. The higher current rating provides design margin and typically offers improved on-resistance characteristics. Package and voltage specifications must remain identical.

Q: What is the operating temperature range difference between MTP3055V and MTP3055VL?

A: The MTP3055V operates from -55°C to 175°C. The MTP3055VL extends the lower temperature limit to -65°C, providing 10°C additional low-temperature performance margin. Both devices maintain the same 175°C upper temperature limit. This difference is significant for applications requiring enhanced cold-temperature operation.
