Engineering Selection Recommendations

The PDZ20B,115 (NXP Semiconductors) is a direct parametric equivalent to the PDZ20B-QZ (Nexperia USA Inc.). Both components are manufactured by entities within the NXP group and share identical electrical specifications and package configurations. Selection between these parts is based on availability, lead time, and procurement requirements rather than technical differentiation.

Both parts maintain active product status and comply with automotive-grade standards (AEC-Q101). The PDZ20B,115 carries ROHS3 compliance and REACH unaffected status, consistent with the primary part specification. Moisture sensitivity classification (MSL 1) indicates unlimited shelf life under standard storage conditions for both variants.

For applications requiring automotive qualification or compliance documentation, both parts satisfy these requirements. Inventory availability should be the primary consideration in component selection, as the PDZ20B,115 currently maintains significantly higher stock levels (100,048 pieces) compared to the PDZ20B-QZ (969 pieces).

Frequently Asked Questions (FAQ)

Q: Can the PDZ20B,115 be used as a direct replacement for the PDZ20B-QZ?

A: Yes. The PDZ20B,115 is a parametric equivalent with identical electrical specifications (20 V nominal Zener voltage, 400 mW power rating, ±2% tolerance) and identical package configuration (SOD-323 surface mount). All electrical and mechanical parameters match the PDZ20B-QZ.

Q: Are there differences in manufacturing or qualification between these parts?

A: Both parts are manufactured by NXP entities and maintain active product status. Both comply with AEC-Q101 automotive qualification standards and ROHS3 requirements. No functional or compliance differences exist between the two part numbers.

Q: What is the significance of the different part number formats (PDZ20B-QZ vs. PDZ20B,115)?

A: The different formats reflect internal NXP numbering conventions and packaging designations. The PDZ20B-QZ includes a tape and reel packaging specification, while PDZ20B,115 represents the same die and electrical specification under an alternative part number designation. Both refer to identical electrical components in SOD-323 packages.

Q: Is the SOD-323 package compatible with existing PCB designs for the PDZ20B-QZ?

A: Yes. Both parts use the SC-76/SOD-323 package, which is a standard surface mount package. PCB footprints, reflow profiles, and assembly processes remain identical between the two part numbers.

Q: What is the moisture sensitivity level, and does it affect storage or handling?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. These components can be stored and handled under standard industrial conditions without special desiccant packaging or shelf-life limitations.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and procurement lead times. The PDZ20B,115 maintains higher stock levels and may offer shorter delivery times. Both parts are suitable for new designs requiring a 20 V, 400 mW Zener diode in SOD-323 packaging with automotive qualification.
