IRF2807ZSPBF N-Channel MOSFET 75V 75A D2PAK Equivalent & Substitute Parts

Part Overview

The IRF2807ZSPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 75V drain-to-source voltage and 75A continuous drain current in a D2PAK surface mount package. This device is part of the HEXFET® series and is classified as discontinued at DiGi Electronics. Due to its discontinued status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing.

Substitute Part Grouping Explanation

Substitution of the IRF2807ZSPBF is determined by the following critical parameters:

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss): Must be ≥75V to maintain voltage margin
Continuous Drain Current (Id): Must be ≥75A to support load requirements
Package Type: Must be D2PAK (TO-263-3) for mechanical and thermal compatibility
Mounting Type: Must be Surface Mount
Operating Temperature Range: Must span -55°C to 175°C
Gate Threshold Voltage (Vgs(th)): Must be ≤4V @ 250µA for gate drive compatibility
Maximum Gate Supply Voltage (Vgs Max): Must be ±20V

Secondary Compatibility Parameters:

On-State Resistance (Rds On): Lower values indicate improved performance; values within 8–11 mOhm are acceptable
Gate Charge (Qg): Lower values reduce switching losses; range 40–235 nC is acceptable
Power Dissipation: Higher ratings provide thermal margin

Substitute parts are grouped into two categories based on voltage rating alignment:

Category A – 75V Rated (Direct Voltage Match): Parts with Vdss = 75V maintain identical voltage specifications and are preferred for direct replacement without circuit redesign.

Category B – 55V to 80V Rated (Voltage Variants): Parts with Vdss between 55V and 80V offer functional substitution with trade-offs in voltage margin or thermal performance. These are suitable when application voltage headroom permits.

Engineering Selection Recommendations

Primary Substitutes (75V Rated, Active Status):

FDB088N08 (onsemi) and STB140NF75T4 (STMicroelectronics) are the preferred substitutes. Both maintain the 75V Vdss specification, are in active production status, and offer improved current handling (120A vs. 75A). FDB088N08 features lower on-state resistance (8.8 mOhm) and is part of the PowerTrench® series. STB140NF75T4 provides the highest power dissipation rating (310W) and is part of the STripFET™ III series. Both are RoHS3 compliant and suitable for direct circuit replacement.

Secondary Substitutes (75V Rated, Active Status):

STB75NF75LT4 (STMicroelectronics) matches the original 75V/75A specification exactly and offers superior thermal performance (300W dissipation vs. 170W). This part is in active production and RoHS3 compliant. The lower gate charge (90 nC) reduces switching losses compared to the original device.

Voltage-Variant Substitutes (80V Rated, Active Status):

HUF75545S3ST, PSMN012-80BS,118, and PSMN8R7-80BS,118 operate at 80V Vdss, providing additional voltage margin. These parts are suitable for applications where the circuit voltage does not exceed 75V and where the extra 5V headroom is beneficial. All three are RoHS3 compliant and in active production.

Lower-Voltage Alternatives (55V Rated, Active Status):

BUK7610-55AL,118, STB140NF55T4, STB141NF55, and IXTA90N055T2 are rated at 55V Vdss. These parts are suitable only for applications where the maximum circuit voltage is below 55V. Use of these parts in circuits designed for 75V operation is not recommended due to insufficient voltage margin.

Compliance and Certification:

All recommended substitutes are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity levels range from MSL 1 (unlimited) to MSL 3 (168 hours). Substitutes with MSL 1 rating (FDB088N08, STB75NF75LT4, PSMN8R7-80BS,118, STB140NF75T4) are preferred for extended shelf life and storage flexibility.

Frequently Asked Questions (FAQ)

Q1: Can I use a 55V-rated MOSFET as a substitute for the IRF2807ZSPBF in a 75V application?

No. The 55V-rated parts (BUK7610-55AL,118, STB140NF55T4, STB141NF55, IXTA90N055T2) have insufficient voltage rating for a 75V application. Using these parts exposes the device to overstress and failure. Substitutes must have Vdss ≥75V.

Q2: What is the difference between the 75V and 80V rated substitutes?

The 80V-rated substitutes (HUF75545S3ST, PSMN012-80BS,118, PSMN8R7-80BS,118) provide 5V additional voltage margin compared to the original 75V specification. They are suitable for circuits operating at or below 75V. The 75V-rated substitutes (FDB088N08, STB75NF75LT4, STB140NF75T4) match the original voltage specification exactly.

Q3: Are all substitute parts available in the same D2PAK package?

Yes. All substitute parts listed are packaged in D2PAK (TO-263-3) surface mount format, ensuring mechanical and thermal compatibility with the original IRF2807ZSPBF footprint.

Q4: Which substitute offers the best thermal performance?

STB140NF75T4 and STB75NF75LT4 both offer 300W power dissipation ratings, compared to 170W for the original IRF2807ZSPBF. STB140NF75T4 provides the highest rating at 310W, making it suitable for high-power applications requiring superior thermal headroom.

Q5: What is the significance of gate charge (Qg) in selecting a substitute?

Gate charge determines the energy required to switch the MOSFET on and off. Lower gate charge (e.g., PSMN012-80BS,118 at 43 nC) reduces switching losses and allows faster switching speeds. Higher gate charge (e.g., HUF75545S3ST at 235 nC) may increase switching losses but does not prevent substitution if other parameters are compatible.

Q6: Can I use FDB088N08 (120A rated) instead of the 75A IRF2807ZSPBF?

Yes. FDB088N08 is rated for 120A continuous drain current, exceeding the 75A requirement. The higher current rating provides design margin and does not create compatibility issues. The device will operate safely at 75A or lower.

Q7: What does "Active" vs. "Discontinued" status mean for component selection?

Active status indicates the part is in current production and available from distributors. Discontinued status means the manufacturer no longer produces the part, making it unavailable for new designs or high-volume production. Active substitutes are strongly preferred for long-term supply chain reliability.

Q8: Are all substitutes RoHS3 compliant?

Yes. All substitute parts listed are RoHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q9: What is the difference between MSL 1 and MSL 3 moisture sensitivity levels?

MSL 1 (Unlimited) allows indefinite shelf storage without moisture baking requirements. MSL 3 (168 hours) requires moisture baking if the part has been exposed to ambient humidity for more than 168 hours before reflow soldering. MSL 1 parts offer greater flexibility in inventory management.

Q10: Which substitute is the best direct replacement for the IRF2807ZSPBF?

STB75NF75LT4 is the best direct replacement, matching the exact 75V/75A specification, D2PAK package, and operating temperature range. It is in active production, RoHS3 compliant, and offers superior thermal performance (300W vs. 170W). FDB088N08 is an alternative with higher current rating (120A) and lower on-state resistance (8.8 mOhm), also in active production.
