TLZ13B-GS18 Equivalent & Substitute Parts

Part Overview

The TLZ13B-GS18 is a Zener diode manufactured by Vishay General Semiconductor - Diodes Division, rated at 13 V nominal with 500 mW power dissipation in a surface mount SOD-80 MiniMELF package. This component is classified as Active and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLZ13B-GS18 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage nominal rating of 13 V
• Maximum power dissipation of 500 mW
• Operating temperature range spanning -65°C to 175°C minimum
• Surface mount technology compatibility

Mechanical Compatibility Criteria:

• Package format: SOD-80 MiniMELF or equivalent surface mount package (DO-213AA, DO-213AC)
• Tape & Reel or Bulk packaging formats both acceptable for substitution

Compliance Criteria:

• RoHS3 compliance preferred for direct substitution
• REACH Unaffected status maintained across all candidates

The substitute parts identified (1N4107UR-1 and CLL5243B TR PBFREE) meet the core electrical specifications of 13 V nominal Zener voltage and 500 mW power rating. Variations in impedance, reverse leakage current, and forward voltage are within acceptable engineering tolerances for Zener diode applications. Package differences between SOD-80 and DO-213AA are functionally equivalent for surface mount assembly.

Parameter Comparison

Engineering Selection Recommendations

CLL5243B TR PBFREE (Central Semiconductor Corp): This substitute provides the closest electrical and mechanical alignment with the TLZ13B-GS18. Both components share identical nominal Zener voltage (13 V), power rating (500 mW), and package format (SOD-80 MiniMELF). The CLL5243B maintains RoHS3 compliance and extends the operating temperature range to 200°C, providing additional thermal margin. Impedance specification (13 Ohms) is nearly equivalent to the main part (14 Ohms). This part is recommended for direct substitution in applications where RoHS3 compliance and package compatibility are required.

1N4107UR-1 (Microchip Technology): This substitute meets the core electrical specifications of 13 V nominal Zener voltage and 500 mW power dissipation with identical operating temperature range (-65 to 175°C). However, this part does not maintain RoHS3 compliance and is packaged in DO-213AA format rather than SOD-80. The impedance specification (200 Ohms) is significantly higher than the main part. This substitute is applicable only in applications where RoHS compliance is not mandated and where DO-213AA package compatibility with existing PCB layouts is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 1N4107UR-1 be used as a direct replacement for the TLZ13B-GS18?

A: The 1N4107UR-1 provides electrical equivalence in Zener voltage (13 V) and power rating (500 mW). However, the package format differs (DO-213AA versus SOD-80 MiniMELF), and RoHS compliance status is not maintained. Substitution requires confirmation of PCB layout compatibility and compliance requirements for the end application.

Q: What is the primary difference between the CLL5243B TR PBFREE and the TLZ13B-GS18?

A: Both parts share identical nominal Zener voltage, power rating, and SOD-80 package format. The CLL5243B provides an extended operating temperature range (-65 to 200°C versus -65 to 175°C) and maintains RoHS3 compliance. Impedance values are nearly equivalent (13 Ohms versus 14 Ohms). This part is suitable for direct substitution.

Q: Does impedance variation affect substitution suitability?

A: Impedance specifications define the dynamic resistance of the Zener diode at specified test conditions. The TLZ13B-GS18 specifies 14 Ohms maximum impedance. The CLL5243B (13 Ohms) is within acceptable tolerance. The 1N4107UR-1 (200 Ohms) represents a significant deviation and may affect circuit performance in applications requiring low impedance characteristics.

Q: Are all substitute parts available in Tape & Reel packaging?

A: The TLZ13B-GS18 and CLL5243B TR PBFREE are both supplied in Tape & Reel format. The 1N4107UR-1 is supplied in Bulk packaging. Tape & Reel format is standard for automated assembly processes.

Q: What compliance considerations apply to these substitutes?

A: The TLZ13B-GS18 and CLL5243B TR PBFREE are both RoHS3 compliant. The 1N4107UR-1 is RoHS non-compliant. All three parts maintain REACH Unaffected status. Applications subject to RoHS regulations must use either the main part or the CLL5243B substitute.

Q: How do reverse leakage current specifications compare?

A: The TLZ13B-GS18 specifies 40 nA @ 11.9 V. The 1N4107UR-1 specifies 50 nA @ 9.9 V. The CLL5243B specifies 500 nA @ 9.9 V. Reverse leakage current is measured at different voltage points across the three parts. The CLL5243B exhibits higher leakage; applications sensitive to leakage current performance should evaluate this parameter against circuit requirements.
