IPB04N03LB N-Channel 30V 80A MOSFET Equivalent & Substitute Parts

Part Overview

The IPB04N03LB is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 30V drain-to-source voltage and 80A continuous drain current in a D2PAK surface mount package. This device is classified as obsolete product status. Due to its obsolescence and limited availability relative to active alternatives, equivalent substitute parts with matching or superior electrical and mechanical specifications are necessary for ongoing design support and production continuity.

Package Type: Must be D2PAK (TO-263-3) or compatible surface mount package
FET Type: Must be N-Channel MOSFET
Operating Temperature Range: Must cover -55°C to 175°C (TJ)
Gate Voltage Rating (Vgs Max): Must be ±20V or greater

Secondary Compatibility Criteria:

Continuous Drain Current (Id): Equal to or greater than 80A

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

PSMN3R4-30BLE,118 and PSMN4R3-30BL,118 are the preferred substitutes for the IPB04N03LB. Both parts are manufactured by Nexperia USA Inc., carry active product status, and are RoHS3 Compliant. These certifications ensure long-term availability and compliance with current environmental regulations. PSMN3R4-30BLE,118 offers the highest continuous drain current rating (120A) and power dissipation capability (178W), providing design margin for thermal and current-handling requirements. PSMN4R3-30BL,118 maintains closer electrical characteristics to the original part while offering improved on-state resistance performance.

Secondary Substitute (Package Consideration):

STD155N3LH6 manufactured by STMicroelectronics is an active, RoHS3 Compliant alternative with matching 80A continuous drain current and 30V Vdss rating. This part uses TO-252 (DPAK) packaging instead of D2PAK. PCB layout modifications are required for this substitution due to different lead configurations and thermal tab positioning. This option is suitable only when PCB redesign is feasible.

Alternative Substitute (Inventory Availability):

PSMN3R4-30BL,118 is available in bulk packaging with the highest inventory level (2018 pcs) among active substitutes. This part maintains D2PAK packaging compatibility and active product status with RoHS3 compliance, though specific RoHS certification status was not provided in the data.

All recommended substitutes maintain the 30V Vdss rating, surface mount capability, and -55°C to 175°C operating temperature range of the original IPB04N03LB.

Frequently Asked Questions (FAQ)

Q: Can PSMN3R4-30BLE,118 directly replace IPB04N03LB without PCB modifications?

A: Yes. Both parts use D2PAK (TO-263-3) packaging with identical lead configurations and thermal tab placement. No PCB layout changes are required for this substitution.

Q: What is the difference between PSMN3R4-30BL,118 and PSMN3R4-30BLE,118?

A: Both parts are manufactured by Nexperia and share the same electrical specifications (30V Vdss, 100A and 120A Id respectively). The primary difference is packaging: PSMN3R4-30BL,118 is supplied in bulk, while PSMN3R4-30BLE,118 is supplied in Tape & Reel format. PSMN3R4-30BLE,118 has higher continuous drain current (120A vs. 100A) and power dissipation (178W vs. 114W).

Q: Why is STD155N3LH6 listed as a substitute if it uses different packaging?

A: STD155N3LH6 meets all electrical requirements (30V Vdss, 80A Id, matching operating temperature range) and is an active, RoHS3 Compliant product. However, it uses TO-252 (DPAK) packaging instead of D2PAK. This substitution requires PCB redesign and is recommended only when layout modifications are acceptable.

Q: Are all substitute parts RoHS3 Compliant?

A: PSMN3R4-30BLE,118, PSMN4R3-30BL,118, and STD155N3LH6 are explicitly RoHS3 Compliant. PSMN3R4-30BL,118 RoHS status was not specified in the provided data. The original IPB04N03LB is RoHS non-compliant.

Q: What is the significance of gate charge (Qg) differences between substitutes?

A: Gate charge affects switching speed and driver circuit requirements. Lower Qg values (PSMN4R3-30BL,118 at 41.5 nC) indicate faster switching response compared to higher values (PSMN3R4-30BLE,118 at 81 nC). For applications with fixed gate driver circuits, verify driver capability matches the substitute part's Qg specification.

Q: Can I use PSMN4R3-30BL,118 in place of PSMN3R4-30BLE,118?

A: Both parts are D2PAK compatible and meet the 30V Vdss requirement. However, PSMN4R3-30BL,118 has lower continuous drain current (100A vs. 120A) and power dissipation (103W vs. 178W). Use PSMN4R3-30BL,118 only if your application does not require the higher current or thermal capability of PSMN3R4-30BLE,118.

Q: What inventory considerations apply to these substitutes?

A: PSMN4R3-30BL,118 has the highest inventory (10,750 pcs), followed by PSMN3R4-30BLE,118 (4,707 pcs), STD155N3LH6 (5,231 pcs), and PSMN3R4-30BL,118 (2,018 pcs). For high-volume production, PSMN4R3-30BL,118 offers the best availability.
