Substitute Part Grouping Explanation

Substitution of the VLZ13-GS18 is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - Zener (Nom): 13 V
• Power - Max: 500 mW
• Impedance (Max): 14 Ohms
• Voltage - Forward (Vf) (Max) @ If: 1.5 V @ 200 mA
• Operating Temperature Range: -65°C to 175°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SOD-80 variant

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Grade: Automotive
• Qualification: AEC-Q101

The TLZ13-GS18 meets all electrical and compliance requirements for direct substitution. Both parts share identical zener voltage, power rating, impedance, forward voltage characteristics, and operating temperature range. Both are surface mount SOD-80 package variants, ROHS3 compliant, and automotive grade with AEC-Q101 qualification.

Engineering Selection Recommendations

The TLZ13-GS18 is the direct substitute for the obsolete VLZ13-GS18. Both components are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, operating temperature range, and compliance certifications.

Selection Basis:

The TLZ13-GS18 maintains full electrical equivalence across all critical parameters: 13 V zener voltage, 500 mW power dissipation, 14 Ohms maximum impedance, and 1.5 V forward voltage at 200 mA. Both parts operate across the identical temperature range of -65°C to 175°C and carry automotive grade qualification with AEC-Q101 certification.

The primary advantage of the TLZ13-GS18 is active product status, ensuring continued availability and supply chain reliability. Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, supporting long-term storage and handling without desiccant requirements.

The SOD-80 package variant difference (QuadroMELF versus MiniMELF) does not affect electrical performance. Both are surface mount configurations suitable for automated assembly processes. The TLZ13-GS18 is supplied in Tape & Reel packaging format, standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the TLZ13-GS18 directly replace the VLZ13-GS18 in existing designs?

A: Yes. The TLZ13-GS18 is electrically and mechanically equivalent to the VLZ13-GS18. All critical parameters including zener voltage, power rating, impedance, forward voltage, and operating temperature range are identical. Both components carry AEC-Q101 automotive qualification and ROHS3 compliance.

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

A: Both are SOD-80 surface mount package variants. The QuadroMELF and MiniMELF designations refer to physical form factor differences, but both maintain the same electrical performance and footprint compatibility for SOD-80 applications. Package selection depends on PCB layout and assembly equipment specifications.

Q: Why is the VLZ13-GS18 listed as obsolete?

A: The VLZ13-GS18 has reached end-of-life status. The TLZ13-GS18 is the active replacement part from the same manufacturer, offering identical electrical specifications and continued supply availability.

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

A: No. Both the VLZ13-GS18 and TLZ13-GS18 are ROHS3 compliant, carry AEC-Q101 automotive qualification, and have MSL 1 (Unlimited) moisture sensitivity rating. Compliance profiles are identical.

Q: What packaging formats are available for the TLZ13-GS18?

A: The TLZ13-GS18 is supplied in Tape & Reel (TR) format, standard for high-volume production and automated assembly processes.

Q: Are the electrical characteristics guaranteed across the full operating temperature range?

A: Yes. Both parts are rated for operation across -65°C to 175°C. All electrical parameters including zener voltage, impedance, and forward voltage are maintained within specification across this temperature range.
