Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ36-GS08 is determined by matching the following critical electrical and mechanical parameters:

• Zener Voltage: 36 V nominal
• Power Dissipation: 500 mW maximum
• Impedance: 75 Ohms maximum
• Forward Voltage: 1.5 V maximum at 200 mA
• Operating Temperature Range: -65°C to 175°C
• Package Type: SOD-80 Surface Mount variants
• Compliance: ROHS3, AEC-Q101 Automotive qualification

The TLZ36-GS08 meets all electrical specifications and operates within the same temperature range. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical performance characteristics. The primary distinction is packaging format: VLZ36-GS08 uses QuadroMELF configuration while TLZ36-GS08 uses MiniMELF configuration, both within the SOD-80 family. The TLZ36-GS08 is currently Active in product status, whereas the VLZ36-GS08 is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The TLZ36-GS08 is the direct electrical equivalent to the VLZ36-GS08 and is the primary substitute for this Obsolete component. All electrical parameters—Zener voltage, power rating, impedance, and forward voltage characteristics—are identical. Both components operate across the full -65°C to 175°C temperature range and maintain ROHS3 compliance.

The key consideration is the package variant: the VLZ36-GS08 uses QuadroMELF while the TLZ36-GS08 uses MiniMELF, both within the SOD-80 family. PCB layout and footprint compatibility must be verified during design transition, as these package variants have different physical dimensions despite sharing the same SOD-80 designation.

The TLZ36-GS08 is currently in Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete VLZ36-GS08. This substitution is appropriate for new designs and end-of-life replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the TLZ36-GS08 directly replace the VLZ36-GS08 in existing designs?

A: Electrical substitution is direct and complete. All electrical parameters match identically. However, physical package dimensions differ between QuadroMELF and MiniMELF variants within the SOD-80 family. PCB footprint verification is required before implementation.

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

A: Both are SOD-80 package variants manufactured by Vishay. QuadroMELF and MiniMELF differ in physical dimensions and lead configuration. Consult the respective component datasheets for precise footprint specifications.

Q: Are both parts suitable for Automotive applications?

A: The VLZ36-GS08 carries explicit Automotive grade designation and AEC-Q101 qualification. The TLZ36-GS08 specifications provided do not include Automotive grade or AEC-Q101 designation. Application requirements must determine whether this distinction is critical for your design.

Q: Why is the VLZ36-GS08 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The TLZ36-GS08, being Active in product status, represents the current production equivalent and is recommended for new procurement.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The VLZ36-GS08 includes AEC-Q101 Automotive qualification; this specification is not provided for the TLZ36-GS08. Verify Automotive qualification requirements for your application.

Q: What is the moisture sensitivity level for these components?

A: Both the VLZ36-GS08 and TLZ36-GS08 have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures.
