Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ5.6BF is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 5.73 V nominal with ±2% tolerance
• Power Rating: 400 mW maximum dissipation
• Package Type: SOD-323 surface mount configuration
• Impedance: 100 Ohms maximum
• Reverse Leakage Current: 1 µA @ 2.5 V
• Forward Voltage: 900 mV maximum @ 10 mA
• Operating Temperature Range: 150°C junction temperature rating

Substitute parts must maintain identical electrical performance across all specified parameters and be housed in the same SOD-323 package to ensure mechanical and thermal compatibility. The PDZ5.6BZ meets all substitution criteria as a direct equivalent within the PDZ5.6 base product family.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ5.6BF and PDZ5.6BZ are active products manufactured by Nexperia USA Inc. with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations rather than performance differentiation. Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The PDZ5.6BZ currently maintains higher inventory levels (30,857 pcs) compared to the PDZ5.6BF (10,956 pcs), which may influence procurement decisions for high-volume production requirements. Both parts are suitable for direct substitution in existing circuit designs without modification to PCB layouts or component footprints.

Frequently Asked Questions (FAQ)

Q: Can PDZ5.6BZ be used as a direct replacement for PDZ5.6BF?

A: Yes. The PDZ5.6BZ is a parametric equivalent with identical zener voltage (5.73 V), power rating (400 mW), impedance (100 Ohms), and SOD-323 package configuration. No circuit modifications are required.

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

A: No. Both parts use the SC-76 SOD-323 package with identical mechanical dimensions and thermal characteristics, ensuring compatibility with existing PCB designs and reflow soldering processes.

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

A: The ±2% tolerance indicates the zener voltage will remain within 5.615 V to 5.845 V across the specified operating range. Both PDZ5.6BF and PDZ5.6BZ maintain this tolerance specification, ensuring equivalent voltage regulation performance.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations and no special storage or handling requirements prior to assembly.

Q: What is the maximum reverse leakage current specification?

A: Both parts specify 1 µA maximum reverse leakage current measured at 2.5 V reverse bias, ensuring equivalent leakage characteristics for circuit design calculations.

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

A: Yes. Both parts are rated for 150°C junction temperature operation, supporting applications requiring extended thermal performance within this operating range.

Q: What regulatory certifications apply to both parts?

A: Both PDZ5.6BF and PDZ5.6BZ are ROHS3 compliant and REACH unaffected, meeting environmental and hazardous substance restrictions for EU and international markets.
