Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ15-GS08 is determined by electrical and mechanical parameter equivalence within the Zener diode category. The critical parameters governing substitution are:

Electrical Parameters:

• Zener voltage: 15 V nominal
• Maximum power dissipation: 500 mW
• Maximum impedance: 16 Ohms
• Forward voltage: 1.5 V maximum at 200 mA
• Operating temperature range: -65°C to 175°C

Mechanical Parameters:

• Surface mount configuration
• SOD-80 package family compatibility
• Automotive grade classification
• AEC-Q101 qualification requirement

The TLZ15-GS08 satisfies all electrical and mechanical substitution criteria. Both components share identical nominal voltage, power rating, impedance specification, forward voltage characteristics, and operating temperature range. Both maintain Automotive grade status with AEC-Q101 qualification and ROHS3 compliance. The primary distinction is packaging variant designation (QuadroMELF versus MiniMELF) within the SOD-80 family, with the substitute part supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can the TLZ15-GS08 be used as a direct replacement for the VLZ15-GS08 in existing designs?

A: Yes. The TLZ15-GS08 is electrically and mechanically equivalent to the VLZ15-GS08. All critical electrical parameters, operating temperature range, and automotive qualifications are identical. Both components are packaged within the SOD-80 family and maintain the same footprint compatibility.

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

A: QuadroMELF and MiniMELF are variant designations within the SOD-80 package family. Both maintain the same electrical performance and footprint specifications. The distinction reflects manufacturing process variants from Vishay General Semiconductor. Both are compatible with standard SOD-80 assembly processes.

Q: Why is the VLZ15-GS08 classified as Obsolete?

A: The VLZ15-GS08 has reached end-of-life status in the manufacturer's product portfolio. The TLZ15-GS08 represents the active continuation of this product line, offering identical electrical and mechanical specifications with ongoing manufacturing support.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the VLZ15-GS08 and TLZ15-GS08 maintain identical compliance profiles: Automotive grade, AEC-Q101 qualified, ROHS3 compliant, and REACH unaffected. Both are suitable for applications requiring automotive-grade Zener diodes.

Q: What is the impact of the packaging format change from standard to Tape & Reel?

A: Tape & Reel format is the standard supply method for high-volume surface mount component assembly. This format change does not affect electrical performance or circuit compatibility. Assembly equipment compatibility should be verified with your manufacturing partner.

Q: Can the TLZ15-GS08 handle the same power dissipation as the VLZ15-GS08?

A: Yes. Both components are rated for 500 mW maximum power dissipation with identical impedance specifications of 16 Ohms maximum. Thermal design considerations remain equivalent between the two parts.
