Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ24BF is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Nominal zener voltage: 24.25 V
• Voltage tolerance: ±2%
• Maximum power dissipation: 400 mW
• Maximum impedance: 30 Ohms
• Reverse leakage current: 50 nA @ 19 V
• Forward voltage: 1.1 V @ 100 mA
• Operating temperature rating: 150°C (TJ)
• Package type: SOD-323 (SC-76)
• Mounting configuration: Surface Mount

The PDZ24BF belongs to the PDZ24 base product family. Substitute parts within this family maintain identical electrical performance specifications and physical package dimensions, ensuring direct interchangeability in circuit applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

The PDZ24BZ is a parametric equivalent substitute for the PDZ24BF. Both components are manufactured by Nexperia USA Inc. and share identical electrical specifications, mechanical packaging, and regulatory compliance status. Selection between PDZ24BF and PDZ24BZ is based on availability and supply chain requirements rather than functional differences.

Both parts maintain active product status and comply with ROHS3 and REACH regulations. The moisture sensitivity level of 1 (Unlimited) indicates no special handling requirements during storage or assembly. The SOD-323 surface mount package is standard for automated PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PDZ24BZ replace PDZ24BF in existing designs?

A: Yes. The PDZ24BZ is a direct parametric equivalent with identical electrical specifications, voltage rating, power dissipation, impedance, and SOD-323 package dimensions. No circuit design changes are required.

Q: Are there differences in the SOD-323 package between these parts?

A: No. Both PDZ24BF and PDZ24BZ use the SC-76 SOD-323 package with identical physical dimensions and pin configuration, ensuring compatibility with existing PCB layouts and assembly equipment.

Q: What is the significance of the ±2% tolerance specification?

A: The ±2% tolerance indicates the maximum deviation of the nominal 24.25 V zener voltage across the specified operating range. Both substitute parts maintain this tolerance, ensuring consistent voltage regulation performance in circuit applications.

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

A: No. Both PDZ24BF and PDZ24BZ have identical moisture sensitivity level ratings of 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.

Q: What is the maximum reverse leakage current specification?

A: Both parts specify a maximum reverse leakage current of 50 nanoamperes measured at 19 V reverse bias. This parameter defines the leakage behavior when the diode is reverse biased below the zener voltage threshold.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both PDZ24BF and PDZ24BZ are rated for operation at junction temperatures up to 150°C (TJ), making them suitable for industrial and automotive applications with elevated ambient temperature requirements.
