Engineering Selection Recommendations

All three part numbers—PDZ30BF, PDZ30BZ, and PDZ30B,115—are functionally equivalent and interchangeable for applications requiring a 30 V, 400 mW zener diode in SOD-323 packaging. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical differences.

Availability Considerations:

PDZ30BZ maintains the highest inventory level at 30,877 pieces, providing optimal supply chain continuity for high-volume production requirements. PDZ30BF contains 10,920 pieces in stock, suitable for standard production runs. PDZ30B,115 maintains 3,400 pieces, appropriate for lower-volume applications or secondary sourcing.

All parts maintain active product status and full compliance with RoHS3, REACH, and MSL requirements, ensuring regulatory conformance across all applications.

Frequently Asked Questions (FAQ)

Q: Can PDZ30BZ be used as a direct replacement for PDZ30BF?

A: Yes. PDZ30BZ is a parametric equivalent with identical electrical specifications (30 V nominal zener voltage, 400 mW power rating, ±2% tolerance) and mechanical specifications (SOD-323 package, surface mount). No circuit modifications are required.

Q: What is the difference between PDZ30BF and PDZ30B,115?

A: There are no electrical or mechanical differences between these parts. Both are 30 V, 400 mW zener diodes in SOD-323 packaging with identical performance characteristics. The part number suffix reflects internal Nexperia designation only.

Q: Are all three parts RoHS3 compliant?

A: Yes. PDZ30BF, PDZ30BZ, and PDZ30B,115 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting regulatory requirements for commercial and industrial applications.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. All three parts share identical SOD-323 packaging and surface mount specifications, enabling direct substitution in pick-and-place assembly processes without tooling or programming changes.

Q: What is the maximum operating temperature for these zener diodes?

A: The maximum junction temperature (TJ) is 150°C for all three part numbers.

Q: Are there any compliance or certification differences between the substitute parts?

A: No. All three parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 classification. No additional certifications or restrictions apply to any variant.
