Key Parameters

Substitute Part Grouping Explanation

Substitution of the J111_D75Z is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on the following criteria:

• FET Type: N-Channel configuration must be maintained
• Voltage Rating: V(BR)GSS of 35 V is the maximum allowable rating
• Drain Current: Idss specification of 20 mA @ 15 V must be matched
• Cutoff Voltage: VGS off of 3 V @ 1 µA defines the switching threshold
• On-State Resistance: RDS(On) of 30 Ohms establishes conduction characteristics
• Power Dissipation: 625 mW maximum rating must not be exceeded
• Temperature Range: Operating range of -55°C to 150°C (TJ) must be supported
• Package Configuration: TO-92-3 Through Hole package with TO-226-3 designation is required

The J111 base product number represents the direct equivalent, available in active production status with identical electrical performance and mechanical compatibility.
