Substitute Part Grouping Explanation

Substitution of the VLZ3V0-GS08 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

  • Zener voltage rating: 3 V (nominal)
  • Maximum power dissipation: 500 mW
  • Forward voltage: 1.5 V maximum at 200 mA
  • Operating temperature range: -65°C to 175°C
  • Impedance characteristics within acceptable tolerance

Mechanical Compatibility Criteria:

  • Surface mount configuration
  • SOD-80 package family (includes QuadroMELF and MiniMELF variants)
  • Automotive grade qualification (AEC-Q101)
  • RoHS3 compliance

The TLZ3V0-GS08 qualifies as a direct substitute based on matching electrical specifications and surface mount SOD-80 packaging, despite differences in series designation and packaging variant (MiniMELF versus QuadroMELF).

Engineering Selection Recommendations

The TLZ3V0-GS08 is the direct substitute for the obsolete VLZ3V0-GS08. Both components are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications for zener voltage, power rating, and forward voltage characteristics. Both maintain the full operating temperature range of -65°C to 175°C and comply with ROHS3 and REACH requirements.

The primary difference is the packaging variant: the substitute uses SOD-80 MiniMELF configuration versus the original QuadroMELF variant. Both are SOD-80 family packages suitable for surface mount assembly. The TLZ3V0-GS08 impedance specification of 80 Ohms maximum is marginally higher than the original 70 Ohms maximum, remaining within acceptable zener diode performance tolerances for typical circuit applications.

The TLZ3V0-GS08 is currently in active production status with available inventory, making it the appropriate selection for applications requiring the VLZ3V0-GS08 electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the TLZ3V0-GS08 be used as a direct replacement for the VLZ3V0-GS08 in existing designs?

A: Yes. Both components share identical zener voltage (3 V), power rating (500 mW), forward voltage (1.5 V @ 200 mA), and operating temperature range (-65°C to 175°C). Both are surface mount SOD-80 family packages and meet automotive AEC-Q101 qualification requirements.

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

A: Both are SOD-80 package variants used for surface mount zener diodes. QuadroMELF and MiniMELF refer to different physical form factors within the SOD-80 family. The MiniMELF variant (TLZ3V0-GS08) is the smaller form factor. PCB layout and footprint compatibility must be verified for your specific application.

Q: Why is the impedance specification different between the two parts?

A: The VLZ3V0-GS08 specifies 70 Ohms maximum impedance, while the TLZ3V0-GS08 specifies 80 Ohms maximum. This 10 Ohm difference is within normal manufacturing tolerance ranges for zener diodes and does not affect functional compatibility in standard circuit applications.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the VLZ3V0-GS08 and TLZ3V0-GS08 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the product status difference between these parts?

A: The VLZ3V0-GS08 is classified as obsolete, indicating it is no longer in active production. The TLZ3V0-GS08 is classified as active, meaning it is currently manufactured and available through distribution channels.
