Substitute Part Grouping Explanation

Substitute parts for the PDZ3.6B-QX are identified based on strict equivalence of electrical and mechanical parameters. The substitution criteria are defined by the following key parameters:

• Voltage - Zener (Nom): 3.6 V
• Tolerance: ±2%
• Power - Max: 400 mW
• Impedance (Max): 90 Ohms
• Current - Reverse Leakage @ Vr: 5 µA @ 1 V
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 100 mA
• Operating Temperature: 150°C (TJ)
• Package / Case: SC-76, SOD-323
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and are suitable for direct substitution in circuit designs. The PDZ3.6B,115 manufactured by NXP Semiconductors satisfies all specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations
