PDZ6.8BF Equivalent & Substitute Parts

Part Overview

The PDZ6.8BF is an active Zener diode manufactured by Nexperia USA Inc., classified within the Diodes, Zener category. This surface mount component operates at a nominal Zener voltage of 6.93 V with a maximum power dissipation of 400 mW in the SOD-323 package. The part is ROHS3 compliant and maintains an unlimited moisture sensitivity level (MSL 1), making it suitable for standard manufacturing environments. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ6.8BF is permissible when the replacement component maintains identical electrical and mechanical specifications. The critical parameters that determine substitutability are:

• Nominal Zener voltage: 6.93 V
• Voltage tolerance: ±2%
• Maximum power dissipation: 400 mW
• Maximum impedance: 60 Ohms
• Reverse leakage current: 500 nA @ 3.5 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature rating: 150°C (TJ)
• Package designation: SOD-323 (SC-76)
• Mounting configuration: Surface Mount

The PDZ6.8BZ is classified as a parametric equivalent because it satisfies all specified electrical and mechanical requirements without deviation. Both components share the same base product number (PDZ6.8), manufacturer (Nexperia USA Inc.), and compliance certifications (ROHS3, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

Both PDZ6.8BF and PDZ6.8BZ are active products manufactured by Nexperia USA Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these components is based on availability and supply chain requirements rather than electrical or mechanical differentiation. The PDZ6.8BZ currently maintains higher inventory levels (27,745 pcs) compared to the PDZ6.8BF (9,757 pcs), making it suitable for high-volume production scenarios where supply continuity is a priority. Both components are functionally interchangeable in all circuit applications requiring a 6.93 V, 400 mW Zener diode in SOD-323 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Are PDZ6.8BF and PDZ6.8BZ electrically identical?

A: Yes. Both components share identical electrical specifications including nominal Zener voltage (6.93 V), tolerance (±2%), maximum power dissipation (400 mW), impedance (60 Ohms maximum), reverse leakage current (500 nA @ 3.5 V), and forward voltage characteristics (900 mV @ 10 mA).

Q: Can PDZ6.8BZ be used as a direct replacement for PDZ6.8BF in existing designs?

A: Yes. The PDZ6.8BZ is a direct substitute. Both components use the identical SOD-323 package, surface mount configuration, and share the same base product number (PDZ6.8). No circuit modifications or PCB layout changes are required.

Q: What is the difference between the PDZ6.8BF and PDZ6.8BZ part numbers?

A: The difference lies in the suffix designation (BF versus BZ), which typically indicates different manufacturing batches or tape reel configurations. All electrical and mechanical specifications remain identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both PDZ6.8BF and PDZ6.8BZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard manufacturing and storage conditions apply.

Q: Can these Zener diodes be used interchangeably in high-volume production?

A: Yes. Both components are suitable for high-volume surface mount assembly. The PDZ6.8BZ offers higher current inventory availability, making it preferable for sustained production runs.
