TLZ36C-GS08 Equivalent & Substitute Parts

Part Overview

The TLZ36C-GS08 is a Zener diode manufactured by Vishay General Semiconductor - Diodes Division, rated at 36 V nominal with 500 mW power dissipation in a surface mount SOD-80 MiniMELF package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs while maintaining circuit functionality.

Substitute Part Grouping Explanation

Substitution of the TLZ36C-GS08 is determined by the following critical parameters:

Electrical Compatibility Criteria:

Zener voltage rating: 36 V nominal
Power dissipation capability: 500 mW minimum
Package type: SOD-80 MiniMELF (DO-213AC)
Surface mount configuration

Mechanical Compatibility Criteria:

Identical package footprint and lead configuration
Surface mount solder compatibility

Performance Tolerance Criteria:

Impedance characteristics within acceptable range for circuit operation
Reverse leakage current specifications
Forward voltage characteristics
Operating temperature range coverage

The CLL5258B TR TIN/LEAD meets these substitution criteria through equivalent electrical ratings and identical mechanical packaging, enabling direct circuit board replacement.

Engineering Selection Recommendations

Primary Selection: TLZ36C-GS08 (Vishay General Semiconductor)

The TLZ36C-GS08 is the preferred component for applications requiring RoHS3 compliance. This part maintains Active product status with established supply availability and meets all regulatory requirements for restricted substance compliance.

Substitute Selection: CLL5258B TR TIN/LEAD (Central Semiconductor)

The CLL5258B TR is electrically equivalent and mechanically compatible for direct substitution in applications where RoHS compliance is not a design requirement. This substitute provides wider operating temperature range (-65 to 200°C versus -65 to 175°C) and lower forward voltage characteristics. The substitute exhibits higher reverse leakage current (100 nA @ 27 V versus 40 nA @ 31.7 V) and lower impedance (70 Ohms versus 75 Ohms), which remain within acceptable operational parameters for 36 V Zener diode applications.

Selection between these parts depends on regulatory compliance mandates and supply chain requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the CLL5258B TR be used as a direct replacement for the TLZ36C-GS08 in all applications?

A: The CLL5258B TR provides electrical and mechanical compatibility for direct circuit board substitution. However, the RoHS non-compliant status of the substitute must be evaluated against application regulatory requirements. If RoHS3 compliance is mandatory, the TLZ36C-GS08 is required.

Q: What are the key electrical differences between these parts?

A: Both parts share identical 36 V nominal Zener voltage and 500 mW power rating. The CLL5258B TR exhibits lower forward voltage (1.25 V versus 1.5 V at 200 mA), lower impedance (70 Ohms versus 75 Ohms), and higher reverse leakage current (100 nA versus 40 nA). These differences are within normal manufacturing variation for Zener diodes and do not affect circuit functionality in standard applications.

Q: Are the packages identical?

A: Yes. Both parts use the SOD-80 MiniMELF package (DO-213AC) with identical surface mount footprints and lead configurations, enabling direct PCB replacement without layout modifications.

Q: What is the operating temperature difference?

A: The CLL5258B TR operates across a wider temperature range (-65 to 200°C) compared to the TLZ36C-GS08 (-65 to 175°C). This provides additional thermal margin for the substitute in high-temperature applications.

Q: Which part should be selected for new designs?

A: For new designs, the TLZ36C-GS08 is recommended due to RoHS3 compliance and established long-term availability. The CLL5258B TR is suitable for legacy designs or applications where RoHS compliance is not applicable.

Q: Is tolerance specification important for substitution?

A: The CLL5258B TR specifies ±5% Zener voltage tolerance, while the TLZ36C-GS08 does not list a tolerance specification in the provided data. Both parts maintain the 36 V nominal rating required for circuit operation. Tolerance specifications should be verified against circuit design requirements for voltage regulation precision.
