• Continuous Drain Current (Id) @ 25°C: 6.8A (Tc)
• Rds On (Max) @ Id, Vgs: 600mOhm @ 4.1A, 10V
• Vgs(th) (Max) @ Id: 4V @ 250µA
• Gate Charge (Qg) (Max) @ Vgs: 18nC @ 10V
• Vgs (Max): ±20V
• Input Capacitance (Ciss) (Max) @ Vds: 390pF @ 25V
• Power Dissipation (Max): 3.7W (Ta), 60W (Tc)
• Operating Temperature: -55°C to 175°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB

The IRF9520SPBF meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent.
