PDZ30B-QZ Zener Diode Equivalent & Substitute Parts

Part Overview

The PDZ30B-QZ is a 30 V, 400 mW Zener diode manufactured by Nexperia USA Inc. in the SOD-323 surface mount package. This component is classified as an active product and carries AEC-Q101 automotive qualification. The PDZ30B-QZ is designed for voltage regulation and protection applications requiring a compact surface mount form factor with automotive-grade reliability.

Substitute parts are identified when electrical parameters, mechanical packaging, and compliance certifications remain equivalent across different part number variants within the same product family. The PDZ30 series from Nexperia provides multiple part number options that satisfy identical functional requirements.

Substitute Part Grouping Explanation

Substitute parts for the PDZ30B-QZ are identified based on strict electrical and mechanical parameter equivalence. All substitute parts must satisfy the following criteria:

Critical Substitution Parameters:

• Voltage - Zener (Nominal): 30 V
• Tolerance: ±2%
• Power - Maximum: 400 mW
• Impedance (Maximum): 40 Ohms
• Current - Reverse Leakage @ 23 V: 50 nA
• Voltage - Forward (Maximum) @ 100 mA: 1.1 V
• Operating Temperature (Junction): 150°C
• Package / Case: SC-76, SOD-323
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below are manufactured by Nexperia USA Inc., carry active product status, and maintain identical electrical specifications and packaging configurations. These parts are interchangeable at the functional level for applications requiring a 30 V Zener diode with 400 mW power dissipation in SOD-323 surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—PDZ30B,115, PDZ30BF, and PDZ30BZ—are functionally equivalent to the PDZ30B-QZ and satisfy identical electrical and mechanical requirements. Selection among these parts is based on availability and supply chain considerations rather than technical differentiation.

Compliance and Certification Status: All parts carry active product status, ROHS3 compliance, and REACH unaffected designation. The PDZ30B-QZ includes automotive grade qualification with AEC-Q101 certification. Substitute parts maintain equivalent compliance profiles and are suitable for applications requiring automotive-grade reliability.

Packaging and Handling: All parts are supplied in Tape & Reel (TR) packaging with SOD-323 surface mount configuration. Moisture Sensitivity Level 1 (Unlimited) indicates no special moisture control requirements during storage or handling.

Part Number Variants: The PDZ30 base product number encompasses multiple part number suffixes (PDZ30B-QZ, PDZ30B,115, PDZ30BF, PDZ30BZ). These variants represent different manufacturing or distribution designations within the Nexperia product line but maintain identical electrical specifications and package configurations.

Frequently Asked Questions (FAQ)

Q: Are PDZ30B,115, PDZ30BF, and PDZ30BZ direct replacements for PDZ30B-QZ?

A: Yes. All three parts are parametric equivalents with identical electrical specifications, package configuration, and compliance certifications. They are interchangeable for applications requiring a 30 V, 400 mW Zener diode in SOD-323 surface mount packaging.

Q: What determines whether a part can substitute for the PDZ30B-QZ?

A: Substitution is determined by equivalence across all critical electrical parameters: Zener voltage (30 V), tolerance (±2%), maximum power (400 mW), impedance (40 Ohms maximum), reverse leakage current (50 nA @ 23 V), forward voltage (1.1 V maximum @ 100 mA), and operating temperature (150°C junction). Package type (SOD-323), mounting method (surface mount), and compliance status must also match.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical SOD-323 package dimensions and surface mount footprints. No PCB layout modifications are required when substituting between PDZ30B-QZ, PDZ30B,115, PDZ30BF, and PDZ30BZ.

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

A: No. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements. Standard component storage and handling procedures apply to all variants.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All parts maintain identical electrical specifications including Zener voltage, tolerance, power rating, impedance, leakage current, and forward voltage characteristics.

Q: What is the significance of the different part number suffixes?

A: The suffixes (such as -QZ, ,115, F, Z) represent different manufacturing or distribution designations within Nexperia's product line. These designations do not affect electrical performance or package configuration.

Q: Are all substitute parts automotive qualified?

A: The PDZ30B-QZ carries explicit AEC-Q101 automotive qualification. All substitute parts maintain equivalent compliance profiles and active product status suitable for automotive applications.

Q: What is the difference between Tape & Reel packaging and other packaging options?

A: Tape & Reel (TR) packaging is a continuous strip format used for automated assembly processes. All listed parts are supplied in this format, ensuring compatibility with standard pick-and-place equipment.
