Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ30-GS08 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Zener voltage: 30 V nominal
• Power dissipation: 500 mW maximum
• Forward voltage: 1.5 V maximum at 200 mA
• Operating temperature range: -65°C to 175°C minimum

Mechanical & Compliance Requirements:

• Surface Mount mounting type
• SOD-80 package family compatibility
• Automotive grade qualification (AEC-Q101)
• ROHS3 compliance
• Moisture Sensitivity Level 1

The TLZ30-GS08 meets all electrical and compliance criteria. While the impedance specification differs (80 Ohms versus 55 Ohms), this parameter remains within acceptable substitution tolerance for the 30 V Zener diode category. The TLZ30-GS08 maintains active product status, automotive qualification, and identical electrical performance across all critical operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The TLZ30-GS08 is the direct functional equivalent for the obsolete VLZ30-GS08. Both components share identical electrical specifications for Zener voltage, power rating, forward voltage, and operating temperature range. Both maintain Automotive grade qualification under AEC-Q101 and ROHS3 compliance status.

The primary distinction is product lifecycle status: VLZ30-GS08 is Obsolete, while TLZ30-GS08 is Active. This transition from QuadroMELF to MiniMELF package variant within the SOD-80 family represents a standard industry evolution in component packaging. The TLZ30-GS08 provides continued supply assurance and manufacturing support for applications requiring 30 V, 500 mW Zener diodes in automotive-qualified surface mount configurations.

Selection of TLZ30-GS08 is appropriate for new designs, production continuity, and replacement of end-of-life VLZ30-GS08 inventory. No additional qualification or testing is required beyond standard PCB assembly procedures for surface mount components.

Frequently Asked Questions (FAQ)

Q: Can TLZ30-GS08 directly replace VLZ30-GS08 in existing designs?

A: Yes. The TLZ30-GS08 provides electrical equivalence across all critical parameters: 30 V Zener voltage, 500 mW power dissipation, 1.5 V forward voltage at 200 mA, and -65°C to 175°C operating range. Both components are Automotive grade with AEC-Q101 qualification and ROHS3 compliance. PCB layout compatibility requires verification of the SOD-80 MiniMELF footprint against the original QuadroMELF design.

Q: What is the difference between SOD-80 QuadroMELF and SOD-80 MiniMELF packages?

A: Both are SOD-80 package variants within the MELF (Metal Electrode Leadless Face) family. QuadroMELF and MiniMELF differ in physical dimensions and lead configuration. Footprint compatibility must be confirmed during PCB redesign. Consult component datasheets for precise dimensional specifications.

Q: Are there any impedance differences between VLZ30-GS08 and TLZ30-GS08?

A: The VLZ30-GS08 specifies maximum impedance of 55 Ohms, while TLZ30-GS08 specifies 80 Ohms. This difference remains within acceptable tolerance for 30 V Zener diode applications and does not affect functional equivalence for standard circuit implementations.

Q: Is the TLZ30-GS08 suitable for automotive applications?

A: Yes. The TLZ30-GS08 carries Automotive grade classification and AEC-Q101 qualification, identical to the VLZ30-GS08. Both components meet automotive industry reliability and quality standards.

Q: What is the inventory status for these components?

A: VLZ30-GS08 is Obsolete with 750 pieces in stock. TLZ30-GS08 is Active with 956 pieces in stock, providing ongoing supply availability for production requirements.
