IRF7324 MOSFET Equivalent & Substitute Parts

Part Overview

The IRF7324 is a dual P-Channel MOSFET array manufactured by Infineon Technologies, configured as a 2P-Channel logic level gate device rated for 20V drain-to-source voltage and 9A continuous drain current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

The IRF7324 operates across a temperature range of -55°C to 150°C and is housed in an 8-SOIC surface mount package. Due to its obsolete status, sourcing direct replacements with identical specifications and improved compliance certifications is essential for production continuity.

Substitute Part Grouping Explanation

Substitution of the IRF7324 is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is established based on the following criteria:

Electrical Parameters (Must Match):

• Drain to Source Voltage (Vdss): 20V
• Continuous Drain Current (Id): 9A @ 25°C
• On-State Resistance (Rds On): 18 mOhm @ 9A, 4.5V
• Gate Threshold Voltage (Vgs(th)): 1V @ 250µA
• Gate Charge (Qg): 63nC @ 5V
• Input Capacitance (Ciss): 2940pF @ 15V
• Maximum Power Dissipation: 2W
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Configuration: 2 P-Channel (Dual)
• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• FET Feature: Logic Level Gate

The IRF7324TRPBF qualifies as a direct substitute based on complete parameter equivalence across all electrical and mechanical specifications. The primary distinction is product status and compliance certification.
