IRLZ34STRL N-Channel MOSFET 60V 30A Equivalent & Substitute Parts

Part Overview

The IRLZ34STRL is an N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage and 30A continuous drain current. The device is housed in a Surface Mount TO-263 (D2PAK) package and is currently in active production status with 1047 pieces in stock inventory.

Equivalent and substitute parts are identified when design requirements permit operation within alternative electrical and mechanical specifications. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or when alternative manufacturers' specifications align with application requirements while maintaining functional compatibility.

Engineering Selection Recommendations

IRLZ34NSTRLPBF (Infineon Technologies)

This substitute part meets all primary substitution criteria with the following considerations:

• Drain to Source Voltage: 55V specification is below the 60V rating of the primary part. This part is suitable for applications where the maximum operating voltage does not exceed 55V.
• Continuous Drain Current: 30A rating matches the primary part specification.
• Package and Mounting: Identical TO-263 (D2PAK) surface mount configuration.
• RoHS Compliance: ROHS3 compliant, providing regulatory advantage over the non-compliant primary part.
• Product Status: Active production with 6700 pieces in stock inventory.

PSMN015-60BS,118 (Nexperia USA Inc.)

This substitute part meets all primary substitution criteria with the following considerations:

• Drain to Source Voltage: 60V specification matches the primary part.
• Continuous Drain Current: 50A rating exceeds the 30A requirement, providing additional current capacity margin.
• Rds On: 14.8 mOhm specification is significantly lower than the primary part, resulting in reduced on-state power dissipation.
• Package and Mounting: Identical TO-263 (D2PAK) surface mount configuration.
• RoHS Compliance: ROHS3 compliant, providing regulatory advantage over the non-compliant primary part.
• Product Status: Active production with 12675 pieces in stock inventory.

Frequently Asked Questions (FAQ)

Q: Can the IRLZ34NSTRLPBF be used as a direct replacement for the IRLZ34STRL?

A: The IRLZ34NSTRLPBF is a functional substitute when the application maximum drain-to-source voltage does not exceed 55V. Both parts share identical continuous drain current ratings (30A), matching gate threshold voltage specifications (2V @ 250µA), and identical TO-263 (D2PAK) package configuration. The substitute part features improved RoHS3 compliance and lower gate charge characteristics.

Q: What is the primary difference between the PSMN015-60BS,118 and the IRLZ34STRL?

A: The PSMN015-60BS,118 maintains the 60V drain-to-source voltage rating and TO-263 (D2PAK) package of the primary part. The key differences are: continuous drain current rating of 50A (versus 30A), significantly lower on-state resistance (14.8 mOhm versus 50 mOhm), and RoHS3 compliance. These characteristics make the PSMN015-60BS,118 suitable for applications requiring higher current capacity or lower power dissipation.

Q: Are all substitute parts in the same package configuration?

A: Yes. The IRLZ34STRL, IRLZ34NSTRLPBF, and PSMN015-60BS,118 are all housed in the TO-263-3 (D2PAK) surface mount package with identical pinout and mechanical dimensions. Direct board-level substitution is possible without PCB layout modification.

Q: What is the significance of the RoHS compliance difference?

A: The primary part IRLZ34STRL is RoHS non-compliant, while both substitute parts (IRLZ34NSTRLPBF and PSMN015-60BS,118) are ROHS3 compliant. RoHS3 compliance indicates the parts meet current regulatory requirements for restricted hazardous substances in electronic equipment. Selection of RoHS3 compliant parts is required for applications subject to RoHS regulations.

Q: Can the PSMN015-60BS,118 be used in applications designed for the IRLZ34STRL?

A: Yes. The PSMN015-60BS,118 meets or exceeds all electrical specifications of the IRLZ34STRL: 60V drain-to-source voltage (matching specification), 50A continuous drain current (exceeding 30A requirement), and identical operating temperature range (-55°C to 175°C). The lower on-state resistance and higher current rating provide performance margin. Identical package configuration permits direct substitution.

Q: What are the moisture sensitivity considerations for these parts?

A: All three parts—IRLZ34STRL, IRLZ34NSTRLPBF, and PSMN015-60BS,118—are rated at Moisture Sensitivity Level (MSL) 1 (Unlimited). This classification indicates no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: How do gate charge specifications affect substitution?

A: Gate charge (Qg) specifications determine the energy required to switch the FET on and off. The IRLZ34STRL specifies 35 nC @ 5V, while the IRLZ34NSTRLPBF specifies 25 nC @ 5V, and the PSMN015-60BS,118 specifies 20.9 nC @ 10V. Lower gate charge values reduce switching losses and enable faster switching operation. Substitute parts with lower gate charge are compatible with the primary part application.
