IRFS4227PBF N-Channel MOSFET 200V 62A Equivalent & Substitute Parts

Part Overview

The IRFS4227PBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 200V drain-to-source voltage with 62A continuous drain current at 25°C. This device is housed in a D2PAK (TO-263-3) surface mount package and delivers 330W maximum power dissipation. The part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production requirements. Suitable alternatives must maintain the same voltage rating, package form factor, and comparable current handling capability while meeting RoHS3 compliance and MSL Level 1 specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the IRFS4227PBF is determined by the following mandatory criteria:

Electrical Parameters:

Drain-to-Source Voltage (Vdss): Must equal 200V
Package Type: Must be D2PAK (TO-263-3) surface mount
Continuous Drain Current (Id): Must support applications requiring 62A or provide comparable current handling
Drive Voltage: Must operate at 10V gate drive
RoHS3 Compliance: Required
MSL Level: Must be Level 1 or equivalent

Substitution Logic: Parts are grouped into three categories based on continuous drain current rating relative to the IRFS4227PBF:

Lower Current Substitutes (39A–40A): PSMN057-200B,118 and STB40NF20 provide reduced current capacity. These are suitable only for applications where the full 62A rating is not required.
Comparable Current Substitutes (61A–65A): STB80N20M5 and SUM65N20-30-E3 maintain current ratings within the operational envelope of the original part. These offer direct functional replacement capability.
Higher Current Substitutes (75A): STB75NF20 exceeds the original current rating and is suitable for designs requiring enhanced current capacity within the same voltage class.

All substitute parts maintain D2PAK packaging, 200V Vdss rating, and RoHS3 compliance. Differences in on-resistance (Rds On), gate charge (Qg), and power dissipation must be evaluated against specific application thermal and switching requirements.

Engineering Selection Recommendations

For Direct Replacement (Comparable Current Capacity):

STB80N20M5 and SUM65N20-30-E3 are the primary candidates for direct substitution. Both maintain active product status, ensuring long-term availability and supply chain stability. STB80N20M5 delivers 61A continuous current with superior on-resistance (23 mOhm), making it optimal for applications prioritizing efficiency. SUM65N20-30-E3 provides 65A capacity with higher power dissipation capability (375W), suitable for thermally demanding applications. Both parts are RoHS3 compliant with MSL Level 1 ratings.

For Current-Reduced Applications:

PSMN057-200B,118 and STB40NF20 are suitable when application requirements permit reduced current handling. PSMN057-200B,118 offers the lowest on-resistance among lower-current options (57 mOhm) and maintains the widest operating temperature range (-55°C to 175°C). STB40NF20 provides moderate on-resistance (45 mOhm) with active status and RoHS3 compliance.

For Enhanced Current Capacity:

STB75NF20 is specified for applications requiring current ratings exceeding the original 62A specification. This part delivers 75A continuous current with competitive on-resistance (34 mOhm) and active product status.

Compliance and Availability:

All substitute parts maintain RoHS3 compliance and MSL Level 1 ratings. Current inventory levels range from 1,267 to 19,250 units across suppliers, ensuring production continuity. Product status verification confirms all substitutes are active, eliminating obsolescence risk associated with the discontinued IRFS4227PBF.

Frequently Asked Questions (FAQ)

Q: Can PSMN057-200B,118 or STB40NF20 be used as direct replacements for IRFS4227PBF?

A: These parts are functionally compatible in D2PAK package and 200V voltage class but deliver reduced continuous drain current (39A and 40A respectively versus 62A). They are suitable only for applications where the full 62A rating is not required. Verify application current requirements before selection.

Q: What is the primary advantage of STB80N20M5 over other substitutes?

A: STB80N20M5 combines 61A continuous current (matching the original specification) with the lowest on-resistance (23 mOhm @ 30.5A, 10V) among all substitutes. This delivers superior efficiency and reduced thermal dissipation in high-current switching applications.

Q: Why does SUM65N20-30-E3 have higher power dissipation (375W) than the original IRFS4227PBF (330W)?

A: SUM65N20-30-E3 is rated for higher power dissipation under case temperature conditions (Tc), indicating enhanced thermal performance capability. This does not affect electrical compatibility but provides additional thermal margin for demanding applications.

Q: Are all substitute parts available in the same D2PAK package?

A: Yes. All substitute parts are specified in D2PAK (TO-263-3) surface mount package with identical lead configuration and PCB footprint compatibility. No layout modifications are required for substitution.

Q: What is the temperature operating range difference between IRFS4227PBF and substitute parts?

A: IRFS4227PBF operates from -40°C to 175°C. Most substitutes extend the lower temperature limit to -55°C, providing enhanced cold-temperature performance. Upper temperature limits vary between 150°C and 175°C depending on the substitute selected. Verify application temperature requirements for final selection.

Q: Do all substitute parts meet RoHS3 and MSL Level 1 requirements?

A: Yes. All five substitute parts are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings, matching the original IRFS4227PBF specifications.

Q: Which substitute offers the best balance of current capacity and on-resistance?

A: STB80N20M5 provides optimal balance with 61A continuous current and 23 mOhm on-resistance. SUM65N20-30-E3 offers slightly higher current (65A) with marginally higher on-resistance (30 mOhm) and superior power dissipation capability (375W).
