PDZ5.1BF Zener Diode Equivalent & Substitute Parts

Part Overview

The PDZ5.1BF is an active surface mount Zener diode manufactured by Nexperia USA Inc., designed for voltage regulation and protection applications. This component operates at a nominal Zener voltage of 5.2 V with 400 mW power dissipation capability in a compact SOD-323 package. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard manufacturing environments without special handling requirements. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ5.1BF is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Nominal Zener voltage: 5.2 V
• Voltage tolerance: ±2%
• Maximum power dissipation: 400 mW
• Maximum impedance: 250 Ohms
• Reverse leakage current: 2 µA @ 1.5 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature range: 150°C (TJ)

Mechanical Parameters (Must Match):

• Package type: SOD-323 (SC-76)
• Mounting type: Surface Mount
• Supplier device package: SOD-323

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The PDZ5.1BZ meets all specified criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ5.1BF and PDZ5.1BZ are active products manufactured by Nexperia USA Inc. with identical electrical specifications and mechanical packaging. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

PDZ5.1BF carries 10,625 pieces in current inventory.

PDZ5.1BZ carries 29,689 pieces in current inventory.

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), eliminating compliance-related constraints in component selection. The choice between these substitutes should be determined by procurement lead time, inventory position, and supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can PDZ5.1BZ be used as a direct replacement for PDZ5.1BF?

A: Yes. The PDZ5.1BZ is a parametric equivalent with identical electrical characteristics (5.2 V nominal Zener voltage, ±2% tolerance, 400 mW power rating, 250 Ohms maximum impedance) and mechanical specifications (SOD-323 package, surface mount). All compliance certifications match.

Q: Are there any differences in package dimensions between these parts?

A: No. Both parts use the SC-76 SOD-323 package with identical mechanical specifications. PCB footprints and assembly processes are interchangeable.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, eliminating special moisture control requirements during storage and handling.

Q: What is the basis for substitution between PDZ5.1BF and PDZ5.1BZ?

A: Substitution is based on complete electrical and mechanical parameter equivalence. Both parts share the same base product number (PDZ5.1), manufacturer, and all specified electrical parameters including Zener voltage, power dissipation, impedance, leakage current, and forward voltage characteristics.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications.
