Key Parameters

Substitute Part Grouping Explanation

Substitution of Zener diodes is determined by equivalence across the following critical parameters:

• Zener Voltage (Vz): Must match at 11 V nominal
• Power Dissipation Rating: Must be 400 mW or greater
• Voltage Tolerance: Must be ±2% or tighter
• Package Type: Must be SOD-323 surface mount compatible
• Reverse Leakage Current: Must not exceed 100 nA @ 8 V
• Forward Voltage: Must not exceed 1.1 V @ 100 mA
• Operating Temperature Range: Must support 150°C junction temperature
• Regulatory Compliance: Must maintain ROHS3 compliance and automotive-grade qualification where applicable

The substitute part PDZ11B,115 meets all electrical and mechanical parameters specified for the PDZ11B-QX, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ11B-QX and PDZ11B,115 are active products manufactured by Nexperia USA Inc. with identical electrical specifications and packaging. Selection between these part numbers is based on availability and supply chain requirements rather than functional differences.

The PDZ11B-QX carries automotive-grade qualification (AEC-Q101) and is explicitly designated for automotive applications. The PDZ11B,115 maintains ROHS3 compliance and equivalent electrical performance. Both components satisfy REACH compliance requirements and carry EAR99 export classification.

For applications requiring explicit automotive qualification documentation, PDZ11B-QX is the primary selection. For general industrial and commercial applications where automotive certification is not mandated, PDZ11B,115 provides equivalent functional performance with higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can PDZ11B,115 be used as a direct replacement for PDZ11B-QX?

A: Yes. Both parts share identical electrical parameters including 11 V zener voltage, 400 mW power rating, ±2% tolerance, and SOD-323 packaging. Electrical and mechanical compatibility is complete.

Q: What is the difference between PDZ11B-QX and PDZ11B,115?

A: The primary difference is automotive qualification designation. PDZ11B-QX carries AEC-Q101 automotive-grade certification. Both parts meet ROHS3 compliance and share all electrical specifications.

Q: Are there packaging differences between these parts?

A: No. Both parts use SC-76, SOD-323 surface mount packaging with identical pin configuration and footprint compatibility.

Q: Which part should be selected for automotive applications?

A: PDZ11B-QX is specified for automotive applications due to AEC-Q101 qualification. PDZ11B,115 is suitable for non-automotive applications requiring equivalent electrical performance.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling precautions are required during storage or assembly.

Q: Can these parts be used interchangeably in production?

A: Interchangeability depends on application requirements. For automotive designs requiring AEC-Q101 certification, PDZ11B-QX must be used. For non-automotive applications, either part is functionally equivalent.
