IPD30N06S2-15 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IPD30N06S2-15 is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 55V drain-to-source voltage and 30A continuous drain current in a TO-252-3 (DPAK) surface mount package. This device is part of the OptiMOS™ series and is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Substitute parts are required when the original IPD30N06S2-15 becomes unavailable or when design flexibility permits selection from active product lines offering equivalent electrical performance within the same package family.

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss): 55V minimum
Continuous Drain Current (Id): 30A or greater at 25°C
Package Type: TO-252-3 (DPAK) surface mount
On-Resistance (Rds On): Performance within acceptable thermal limits
Gate Threshold Voltage (Vgs(th)): Compatible gate drive requirements
Operating Temperature Range: -55°C to 175°C minimum

Substitution Categories:

Category 1 – Direct Electrical Equivalent (Same Vdss, Id ≥ 30A) Parts meeting or exceeding the 55V/30A specification with comparable Rds On performance and identical package type.

Category 2 – Higher Current Rating (Vdss = 55V, Id > 30A) Parts with 55V rating and current ratings exceeding 30A, offering improved thermal performance and lower on-resistance.

Category 3 – Voltage Margin Parts (Vdss > 55V, Id ≥ 30A) Parts with voltage ratings above 55V and equivalent or higher current ratings, suitable for applications requiring additional voltage headroom.

Category 4 – Reduced Current Parts (Vdss = 55V, Id < 30A) Parts with 55V rating but lower current ratings, applicable only when circuit design permits reduced current handling.

Engineering Selection Recommendations

Recommended Primary Substitute: IPD30N06S215ATMA2

The IPD30N06S215ATMA2 is the direct equivalent to the IPD30N06S2-15, manufactured by Infineon Technologies. This part maintains identical electrical specifications (55V, 30A, 14.7mOhm Rds On) and package configuration. The primary distinction is product status: IPD30N06S215ATMA2 is active and available in Tape & Reel packaging, whereas the original part is discontinued. This substitution requires no circuit redesign and provides pin-for-pin compatibility.

Secondary Substitute: STD60NF55LT4

The STD60NF55LT4 from STMicroelectronics offers 55V/60A rating with 15mOhm Rds On @ 30A, providing improved thermal performance and current headroom. This part is active and AEC-Q101 qualified for automotive applications. The higher current rating (60A vs. 30A) and lower on-resistance result in reduced power dissipation, making this suitable for designs where thermal margin is critical.

Alternative Substitute: STD60NF55LAT4

The STD60NF55LAT4 is functionally similar to STD60NF55LT4 with 55V/60A rating and 15mOhm Rds On @ 30A. This part carries AEC-Q101 automotive qualification and is active. Selection between STD60NF55LAT4 and STD60NF55LT4 depends on specific supply chain availability and packaging requirements (Cut Tape vs. standard distribution).

Not Recommended for Direct Substitution:

IRFR4105TRPBF: Reduced current rating (27A) and higher on-resistance (45mOhm @ 16A) result in insufficient current capacity and higher power dissipation for applications requiring full 30A operation.
IRFR4105ZTRPBF: Classified as "Not For New Designs" by manufacturer; limited availability and obsolescence risk.
BUK7212-55B,118: Classified as obsolete; not suitable for new production.
FQD30N06TM: Reduced current rating (22.7A) and higher voltage rating (60V) introduce design margin changes; higher on-resistance (45mOhm @ 11.4A) increases power dissipation.

Frequently Asked Questions (FAQ)

Q1: Can I use IRFR4105TRPBF as a direct replacement for IPD30N06S2-15?

No. The IRFR4105TRPBF has a maximum continuous drain current of 27A, which is below the 30A specification of the IPD30N06S2-15. Additionally, the on-resistance is 45mOhm @ 16A compared to 14.7mOhm @ 30A for the original part, resulting in significantly higher power dissipation. This part is suitable only for applications designed for 27A maximum current.

Q2: What is the difference between IPD30N06S2-15 and IPD30N06S215ATMA2?

Both parts are manufactured by Infineon Technologies and share identical electrical specifications: 55V, 30A, 14.7mOhm Rds On, and TO-252-3 package. The primary difference is product status and packaging format. IPD30N06S215ATMA2 is active and supplied in Tape & Reel format, while IPD30N06S2-15 is discontinued. The IPD30N06S215ATMA2 is the direct replacement for ongoing production.

Q3: Why would I choose STD60NF55LT4 over IPD30N06S215ATMA2?

The STD60NF55LT4 offers higher current rating (60A vs. 30A) and improved thermal performance with 15mOhm on-resistance @ 30A. If your application requires additional current headroom or operates at elevated temperatures, the STD60NF55LT4 provides better thermal margin. However, if your circuit is designed specifically for 30A operation, the IPD30N06S215ATMA2 is the more direct equivalent.

Q4: Are all substitute parts in the same TO-252-3 package?

Yes. All substitute parts listed in this reference are housed in TO-252-3 (DPAK) surface mount packages with identical pin configurations and footprints. This ensures mechanical and electrical compatibility without PCB redesign.

Q5: What does "Not For New Designs" mean for IRFR4105ZTRPBF?

"Not For New Designs" indicates that the manufacturer (Infineon) has classified this part as legacy and does not recommend its use in new product development. While existing inventory may be available, the part is subject to discontinuation without notice. New designs should use active alternatives such as IPD30N06S215ATMA2 or STD60NF55LT4.

Q6: Can I use FQD30N06TM as a substitute?

The FQD30N06TM has a reduced continuous drain current rating of 22.7A, which is below the 30A requirement of the IPD30N06S2-15. Additionally, the voltage rating is 60V instead of 55V, and the on-resistance is 45mOhm @ 11.4A, significantly higher than the original 14.7mOhm @ 30A. This part is not suitable for applications requiring full 30A operation and introduces design margin changes.

Q7: What is the significance of RoHS3 compliance?

All parts listed in this reference are RoHS3 compliant, indicating compliance with the Restriction of Hazardous Substances Directive. This ensures compatibility with environmental regulations and procurement requirements for commercial and industrial applications.

Q8: Does operating temperature range affect substitution?

All substitute parts maintain the -55°C to 175°C operating temperature range of the original IPD30N06S2-15, with the exception of FQD30N06TM, which is rated to 150°C. For applications operating above 150°C, FQD30N06TM is not suitable. All other substitutes are compatible across the full temperature range.
