IRF1607 N-Channel MOSFET 75V 142A TO-220AB Equivalent & Substitute Parts

Part Overview

The IRF1607 is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 75V drain-to-source voltage with 142A continuous drain current at 25°C. This device features the HEXFET® series technology and is housed in a TO-220AB through-hole package. The IRF1607 is classified as obsolete product status, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the 75V voltage class, support comparable current ratings, and preserve the TO-220AB package form factor for direct board-level replacement.

Substitute Part Grouping Explanation

Substitution logic for the IRF1607 is based on the following critical parameters:

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss): 75V or higher
Continuous Drain Current (Id): Minimum 120A at 25°C
Package Type: TO-220AB or compatible TO-220-3 through-hole
Gate Drive Voltage: 10V nominal
Operating Temperature Range: -55°C to 175°C minimum

Substitution Categories:

Category 1: Direct Infineon HEXFET® Replacements (Preferred) Parts IRFB3077PBF, IRFB3207ZPBF, and IRFB3307ZPBF are Infineon HEXFET® series devices with identical 75V Vdss rating and TO-220AB packaging. These parts maintain the same gate drive characteristics and thermal operating range. Current ratings range from 120A, which is lower than the IRF1607's 142A, but within acceptable substitution parameters for most applications. All three are active product status with RoHS3 compliance.

Category 2: Cross-Manufacturer 75V Alternatives Parts FDP060AN08A0 (onsemi PowerTrench®) and IXUV170N075 (IXYS) maintain the 75V Vdss specification. FDP060AN08A0 provides 80A continuous current (Tc) with 255W power dissipation. IXUV170N075 offers 175A continuous current, exceeding IRF1607 specifications, but uses PLUS220 package variant.

Category 3: Higher Voltage Alternatives (80V Class) Parts STP140N8F7 (STMicroelectronics), CSD19501KCS (Texas Instruments), PSMN012-80PS,127, and PSMN017-80PS,127 (Nexperia) operate at 80V Vdss, providing voltage margin above the IRF1607's 75V rating. These are suitable where voltage headroom is beneficial. Current ratings vary from 50A to 100A.

Category 4: Lower Voltage Alternative (60V Class) Part FDP5800 (onsemi) operates at 60V Vdss, which is below the IRF1607's 75V specification and is suitable only for applications with reduced voltage requirements.

Engineering Selection Recommendations

Recommended Primary Substitutes (Infineon HEXFET® Series):

IRFB3077PBF, IRFB3207ZPBF, and IRFB3307ZPBF are the preferred substitutes for the IRF1607. All three maintain the 75V Vdss specification, TO-220AB package compatibility, and identical operating temperature range (-55°C to 175°C). These parts are active product status with RoHS3 compliance, addressing the obsolescence and regulatory compliance limitations of the IRF1607. IRFB3077PBF offers the lowest on-state resistance (3.3 mOhm) and highest gate charge (220 nC), providing optimal switching performance. IRFB3207ZPBF balances performance with moderate gate charge (170 nC). IRFB3307ZPBF features the lowest gate charge (110 nC) and power dissipation (230W), suitable for applications prioritizing switching speed and thermal management.

Secondary Substitutes (Cross-Manufacturer 75V Alternatives):

FDP060AN08A0 (onsemi PowerTrench®) maintains 75V Vdss and TO-220-3 package compatibility with 80A continuous current and 255W power dissipation. This part is active status with RoHS3 compliance. IXUV170N075 (IXYS) exceeds IRF1607 current specifications at 175A but uses PLUS220 package, requiring board layout verification for mechanical compatibility.

Tertiary Substitutes (80V Alternatives with Voltage Margin):

STP140N8F7 (STMicroelectronics), CSD19501KCS (Texas Instruments), and Nexperia PSMN series parts operate at 80V Vdss, providing 5V voltage margin above the IRF1607 specification. These are suitable for applications where additional voltage headroom is beneficial. Current ratings range from 50A to 100A. All active-status parts carry RoHS3 compliance. Nexperia PSMN012-80PS,127 and PSMN017-80PS,127 are obsolete status and should be avoided for new designs.

Not Recommended:

FDP5800 operates at 60V Vdss, below the IRF1607's 75V specification, and is suitable only for applications with reduced voltage requirements where the lower voltage rating does not compromise circuit performance.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace IRF1607 with IRFB3307ZPBF without circuit modifications?

A: Yes. IRFB3307ZPBF maintains identical 75V Vdss, TO-220AB package, and -55°C to 175°C operating temperature range. The 120A continuous current is lower than IRF1607's 142A, but the part is suitable for applications where the actual operating current does not exceed 120A. Gate drive voltage (10V) and threshold voltage (4V @ 250µA) are identical, requiring no gate drive circuit changes.

Q2: What is the difference between IRFB3077PBF, IRFB3207ZPBF, and IRFB3307ZPBF?

A: All three are Infineon HEXFET® 75V, 120A parts in TO-220AB packages. Primary differences are on-state resistance, gate charge, and power dissipation. IRFB3077PBF has the lowest Rds On (3.3 mOhm) and highest gate charge (220 nC), optimizing for conduction losses. IRFB3207ZPBF provides mid-range performance (4.1 mOhm, 170 nC). IRFB3307ZPBF has the highest Rds On (5.8 mOhm) but lowest gate charge (110 nC) and power dissipation (230W), optimizing for switching speed and thermal performance. Selection depends on application priorities: conduction loss minimization, switching speed, or thermal management.

Q3: Can I use 80V-rated parts like STP140N8F7 or CSD19501KCS as substitutes?

A: Yes, with application verification. These parts provide 5V voltage margin above the IRF1607's 75V specification. However, continuous current ratings are lower (90A for STP140N8F7, 100A for CSD19501KCS) than the IRF1607's 142A. Use these parts only if actual operating current does not exceed the substitute part's rating. Package compatibility must be verified: STP140N8F7 uses TO-220 (not TO-220AB), and CSD19501KCS uses TO-220-3, which may require board layout adjustment.

Q4: Why is the IRF1607 obsolete, and what does this mean for my design?

A: The IRF1607 is classified as obsolete product status by Infineon, indicating it is no longer in active production. Obsolete parts have limited availability and no guaranteed long-term supply. For new designs and ongoing production, active-status substitutes such as IRFB3077PBF, IRFB3207ZPBF, or IRFB3307ZPBF are required. These active parts ensure supply continuity and compliance with current RoHS3 regulations.

Q5: What is the significance of RoHS3 compliance versus non-compliant status?

A: The IRF1607 is RoHS non-compliant, meaning it may contain restricted substances such as lead. RoHS3-compliant parts (IRFB3077PBF, IRFB3207ZPBF, IRFB3307ZPBF, and others) meet current environmental regulations and are required for applications subject to RoHS directives. For new designs and regulated markets, RoHS3-compliant substitutes are mandatory.

Q6: Can IXUV170N075 replace IRF1607 directly?

A: IXUV170N075 maintains 75V Vdss and exceeds current specifications at 175A. However, it uses PLUS220 package (short tab variant), which differs from the IRF1607's TO-220AB package. Board-level mechanical compatibility must be verified before substitution. Additionally, critical electrical parameters (Rds On, gate charge, power dissipation) are not specified in available data, requiring manufacturer documentation review.

Q7: What inventory considerations apply to these substitutes?

A: IRFB3307ZPBF has the highest inventory (55,200 pcs), followed by IRFB3077PBF (36,409 pcs) and IRFB3207ZPBF (20,100 pcs). These Infineon parts offer reliable supply. Cross-manufacturer alternatives have lower inventory: FDP060AN08A0 (1,728 pcs), CSD19501KCS (5,648 pcs), and STP140N8F7 (3,210 pcs). For high-volume production, Infineon HEXFET® series parts are preferred due to availability.
