Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLZ47-GS08 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage nominal rating: 47 V
• Maximum power dissipation: 500 mW
• Package type: SOD-80 MiniMELF (DO-213AC)
• Surface mount configuration
• Operating temperature range compatibility

Compliance & Regulatory Equivalence:

• RoHS3 compliance status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH unaffected status
• ECCN and HTSUS classifications

The BZV55-C47,115 manufactured by Nexperia USA Inc. satisfies all substitution criteria through identical nominal Zener voltage (47 V), matching maximum power rating (500 mW), and compatible SOD-80 MiniMELF package configuration. Both components maintain equivalent regulatory compliance and environmental classifications.

Engineering Selection Recommendations

Primary Part: TLZ47-GS08

The TLZ47-GS08 is the specified component for applications requiring the exact electrical and thermal characteristics defined by Vishay General Semiconductor. This part maintains active product status with substantial inventory availability (10,400 units). Selection of the primary part is appropriate when supply from the original manufacturer is available and design validation has been completed against Vishay specifications.

Substitute Part: BZV55-C47,115

The BZV55-C47,115 from Nexperia USA Inc. serves as a direct substitute when TLZ47-GS08 availability is constrained or when extended operating temperature range (-65 to 200°C versus -65 to 175°C) is required. Both components maintain identical RoHS3 compliance, MSL 1 classification, and REACH unaffected status. The Nexperia part is actively stocked with 11,331 units available. The substitute part is electrically and mechanically compatible for applications operating within the TLZ47-GS08 temperature specification.

Selection between these parts is based on supply availability, inventory status, and application temperature requirements. Both components are suitable for production use without design modification when package and electrical parameters are verified against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the BZV55-C47,115 be used as a direct replacement for the TLZ47-GS08 in existing designs?

A: Yes. Both components share identical nominal Zener voltage (47 V), maximum power dissipation (500 mW), and SOD-80 MiniMELF package configuration. The electrical and mechanical interfaces are compatible. Designs operating within the TLZ47-GS08 temperature range (-65 to 175°C) require no modification.

Q: What are the differences in impedance between these parts?

A: The TLZ47-GS08 specifies maximum impedance of 90 Ohms, while the BZV55-C47,115 specifies 170 Ohms maximum. This difference reflects manufacturer-specific characterization. Applications sensitive to impedance performance should verify circuit tolerance against both specifications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TLZ47-GS08 and BZV55-C47,115 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification. Both are REACH unaffected and carry identical ECCN and HTSUS classifications.

Q: What is the temperature range difference between these parts?

A: The TLZ47-GS08 operates from -65 to 175°C. The BZV55-C47,115 extends the upper limit to 200°C. Applications requiring operation above 175°C must use the Nexperia part. Applications within the -65 to 175°C range are compatible with either component.

Q: Are the forward voltage characteristics equivalent?

A: Forward voltage is specified under different test conditions. The TLZ47-GS08 specifies 1.5 V maximum at 200 mA, while the BZV55-C47,115 specifies 900 mV at 10 mA. These measurements are not directly comparable due to different test currents. Circuit designs should reference the appropriate datasheet for the selected component.

Q: Can these parts be interchanged in mid-production?

A: Yes, provided that the circuit design has been validated against both component specifications. The identical package, nominal Zener voltage, and power rating support interchangeability. Compliance certifications and environmental classifications are equivalent.

Q: What is the reverse leakage current difference?

A: The TLZ47-GS08 specifies 40 nA at 41.8 V, while the BZV55-C47,115 specifies 50 nA at 32.9 V. These measurements are taken at different reference voltages and are comparable within typical application tolerances for 47 V Zener diodes.
