Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLZ13C-GS08 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Zener voltage: 13 V nominal
• Power dissipation: 500 mW maximum
• Mounting type: Surface Mount
• Operating temperature range: Minimum -65°C to 175°C
• Package compatibility: DO-213AC, MINI-MELF, or SOD-80 variants

Secondary Compatibility Factors:

• Impedance (Zzt): Maximum allowable value determines circuit performance in regulation applications
• Reverse leakage current: Lower values indicate superior performance in low-current applications
• Forward voltage: Affects power loss in forward-biased conditions
• Regulatory compliance: RoHS3 status and REACH classification

The substitute parts listed below meet the primary substitution criteria and are electrically and mechanically compatible with the TLZ13C-GS08 in standard voltage regulation and protection circuits.

Engineering Selection Recommendations

TLZ13C-GS08 (Vishay General Semiconductor)

Primary selection for applications requiring RoHS3 compliance and standard impedance performance. The TLZ13C-GS08 offers the lowest impedance specification (14 Ohms maximum) among the three options, providing superior voltage regulation stability. Recommended for designs with strict regulatory requirements and established supply chain relationships with Vishay components. Current inventory of 15,905 units supports high-volume production.

BZV55-B13,115 (Nexperia USA Inc.)

Direct mechanical and electrical equivalent with enhanced performance characteristics. The BZV55-B13,115 maintains RoHS3 compliance, offers tighter tolerance (±2% versus unspecified), and extends operating temperature range to 200°C. Impedance specification of 30 Ohms is acceptable for most voltage regulation applications. This part is recommended as the primary substitute when TLZ13C-GS08 availability is constrained. Inventory of 6,560 units is available in Tape & Reel packaging.

1N4107UR-1 (Microchip Technology)

Electrical compatibility exists for basic voltage regulation applications; however, this part does not meet RoHS3 compliance requirements and is classified as RoHS non-compliant. The 1N4107UR-1 exhibits higher impedance (200 Ohms maximum) and different package specification (DO-213AA versus SOD-80). Selection of this substitute is limited to applications where RoHS compliance is not mandated and where higher impedance is acceptable. Not recommended for new designs or applications requiring regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1N4107UR-1 be used as a direct replacement for the TLZ13C-GS08?

A: The 1N4107UR-1 shares the same 13 V nominal zener voltage and 500 mW power rating, making it electrically compatible for basic voltage regulation functions. However, the package specification differs (DO-213AA versus SOD-80 MiniMELF), and the part is RoHS non-compliant. Physical board layout modifications may be required. Use only in applications where RoHS compliance is not required.

Q: What is the primary difference between the BZV55-B13,115 and TLZ13C-GS08?

A: Both parts are mechanically and electrically compatible with identical 13 V zener voltage and 500 mW power ratings. The BZV55-B13,115 offers tighter tolerance (±2% versus unspecified), lower impedance (30 Ohms versus 14 Ohms), and extended temperature range (-65°C to 200°C versus -65°C to 175°C). Both maintain RoHS3 compliance and SOD-80 MiniMELF packaging.

Q: Are all three parts suitable for RoHS3-compliant applications?

A: No. Only the TLZ13C-GS08 and BZV55-B13,115 are RoHS3 compliant. The 1N4107UR-1 is classified as RoHS non-compliant and cannot be used in applications requiring regulatory compliance documentation.

Q: What does impedance (Zzt) mean in the context of zener diode selection?

A: Impedance (Zzt) represents the dynamic resistance of the zener diode in the reverse-biased region. Lower impedance values provide better voltage regulation stability and lower output impedance. The TLZ13C-GS08 has the lowest impedance (14 Ohms), followed by BZV55-B13,115 (30 Ohms), and 1N4107UR-1 (200 Ohms). For precision voltage regulation applications, lower impedance is preferred.

Q: Can the BZV55-B13,115 operate at higher temperatures than the TLZ13C-GS08?

A: Yes. The BZV55-B13,115 operates across -65°C to 200°C, while the TLZ13C-GS08 operates across -65°C to 175°C. The BZV55-B13,115 is suitable for applications requiring extended high-temperature performance.

Q: What is the significance of reverse leakage current specifications?

A: Reverse leakage current indicates the amount of current flowing through the zener diode when reverse-biased below the zener voltage. Lower leakage current values indicate superior performance in low-current applications and reduced power consumption. The TLZ13C-GS08 exhibits the lowest leakage (40 nA @ 12.3 V), making it optimal for low-power circuits.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture handling or storage requirements during manufacturing and assembly.
