Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ6.8B-QZ are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Nominal Zener voltage: 6.8 V
• Voltage tolerance: ±2%
• Maximum power dissipation: 400 mW
• Maximum impedance: 40 Ohms
• Reverse leakage current: 500 nA @ 3.5 V
• Forward voltage: 1.1 V @ 100 mA
• Operating temperature rating: 150°C (TJ)
• Package designation: SOD-323 (SC-76)
• Mounting configuration: Surface Mount
• Automotive grade classification and AEC-Q101 qualification

The PDZ6.8B,115 is classified as a parametric equivalent to the PDZ6.8B-QZ. Both parts share identical electrical characteristics and mechanical specifications, with the difference residing in packaging designation and inventory sourcing from the same manufacturer. This substitution maintains full compatibility in circuit applications requiring 6.8 V Zener regulation at 400 mW power levels.

Parameter Comparison

Engineering Selection Recommendations

Both the PDZ6.8B-QZ and PDZ6.8B,115 are Active products manufactured by Nexperia USA Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements rather than technical performance differences.

The PDZ6.8B-QZ is suitable for applications requiring the specific packaging designation associated with the -QZ suffix. The PDZ6.8B,115 provides an alternative sourcing option with higher current inventory availability (18,200 pieces versus 1,098 pieces) while maintaining full parametric equivalence.

Both parts carry ROHS3 compliance, REACH Unaffected status, and AEC-Q101 automotive qualification, ensuring suitability for regulated automotive and industrial applications. The Moisture Sensitivity Level of 1 (Unlimited) indicates no special moisture handling requirements during storage or assembly.
