Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ2.7B-QZ is determined by strict equivalence across the following critical parameters:

• Voltage - Zener (Nom) (Vz): 2.7 V
• Tolerance: ±2%
• Power - Max: 400 mW
• Impedance (Max) (Zzt): 100 Ohms
• Current - Reverse Leakage @ Vr: 20 µA @ 1 V
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 100 mA
• Operating Temperature: 150°C (TJ)
• Package / Case: SC-76, SOD-323
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical specifications and package configuration. Substitutes differ only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging). The PDZ2.7B-QX variant includes Automotive grade qualification and AEC-Q101 certification, matching the original part's automotive qualification status.

Parameter Comparison

Engineering Selection Recommendations

PDZ2.7B-QX is the primary substitute for PDZ2.7B-QZ. Both parts carry Automotive grade classification and AEC-Q101 qualification, ensuring equivalent compliance for automotive applications. The PDZ2.7B-QX is in Active product status with established supply availability, addressing the obsolescence of the original part while maintaining all electrical and thermal specifications.

PDZ2.7B,115 and PDZ2.7B,135 are parametric equivalents with identical electrical characteristics and package configuration. These parts are in Active product status and available in Tape & Reel packaging format. Selection between these variants depends on packaging requirements and supply chain logistics. Neither part specifies Automotive grade or AEC-Q101 qualification; use in automotive applications requires verification of application requirements against qualification standards.

All three substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can PDZ2.7B,115 or PDZ2.7B,135 be used as direct replacements for PDZ2.7B-QZ in automotive applications?

A: PDZ2.7B,115 and PDZ2.7B,135 are parametrically equivalent and electrically identical. However, these parts do not specify Automotive grade or AEC-Q101 qualification. For automotive applications requiring these certifications, PDZ2.7B-QX is the appropriate substitute. For non-automotive applications, PDZ2.7B,115 and PDZ2.7B,135 are functionally equivalent.

Q: What is the difference between PDZ2.7B-QX and the other substitute parts?

A: PDZ2.7B-QX carries Automotive grade classification and AEC-Q101 qualification, matching the original PDZ2.7B-QZ specifications. PDZ2.7B,115 and PDZ2.7B,135 do not specify these qualifications. All three parts share identical electrical parameters, voltage ratings, power dissipation, and SOD-323 package configuration.

Q: Are the Tape & Reel packaged variants (PDZ2.7B,115 and PDZ2.7B,135) compatible with existing PCB assembly processes?

A: Yes. Tape & Reel packaging is standard for automated surface mount assembly. The SOD-323 package dimensions and lead configuration remain identical across all variants. Assembly equipment compatibility depends on feeder specifications for the Tape & Reel format, not on electrical or mechanical part characteristics.

Q: Why is PDZ2.7B-QZ marked as Obsolete?

A: PDZ2.7B-QZ has been discontinued from active production by Nexperia USA Inc. The substitute parts PDZ2.7B-QX, PDZ2.7B,115, and PDZ2.7B,135 are in Active product status and represent the current production alternatives with equivalent specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PDZ2.7B-QX, PDZ2.7B,115, and PDZ2.7B,135 are all ROHS3 compliant and REACH unaffected, matching the compliance status of the original PDZ2.7B-QZ.

Q: What is the moisture sensitivity level for these Zener diodes?

A: All parts, including the main part and substitutes, carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
