Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TZMC36-GS18 are classified based on electrical parameter equivalence and mechanical compatibility. The substitution logic is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Zener (Nominal): 36 V
• Power - Maximum: 500 mW
• Package / Case: SOD-80 MiniMELF
• Mounting Type: Surface Mount

Tolerance Variations: Substitute parts are grouped into two categories based on Zener voltage tolerance specifications. The TZMC36-GS18 operates at ±5% tolerance. Substitute parts with tighter tolerance specifications (±2%) provide improved voltage regulation accuracy but remain electrically compatible for applications where the nominal 36 V specification is the primary design requirement.

Parametric Equivalents: Parts matching all critical electrical parameters and package specifications are classified as parametric equivalents. These include the TZMB36-GS08 (±2% tolerance) and TZMC36-GS08 (±5% tolerance), both from Vishay General Semiconductor - Diodes Division.

Manufacturer-Recommended Equivalent: The CLL5258B TR TIN/LEAD from Central Semiconductor Corp is a manufacturer-recommended substitute with identical nominal Zener voltage and power rating. This part exhibits minor variations in impedance (70 Ohms versus 80 Ohms) and forward voltage characteristics, with an extended operating temperature range to 200°C.

Parameter Comparison

Engineering Selection Recommendations

TZMB36-GS08 Selection: The TZMB36-GS08 is a direct parametric equivalent with improved voltage tolerance specification (±2% versus ±5%). This part maintains identical electrical performance across all critical parameters, including impedance, reverse leakage current, and forward voltage characteristics. Both parts carry AEC-Q101 automotive qualification and RoHS3 compliance. Selection of the TZMB36-GS08 is appropriate for applications requiring tighter Zener voltage regulation accuracy. Current inventory of 1,415 units supports standard procurement volumes.

TZMC36-GS08 Selection: The TZMC36-GS08 is a parametric equivalent with identical electrical specifications and tolerance to the TZMC36-GS18. Both parts are from the same TZM series, carry AEC-Q101 qualification, and maintain RoHS3 compliance. The primary distinction is packaging configuration. With 50,400 units in stock, the TZMC36-GS08 offers superior availability for high-volume production requirements.

CLL5258B TR TIN/LEAD Selection: The CLL5258B TR TIN/LEAD from Central Semiconductor Corp is a manufacturer-recommended substitute with matching nominal Zener voltage and power rating. This part exhibits lower impedance (70 Ohms) and reduced forward voltage (1.25 V at 200 mA), resulting in improved efficiency characteristics. The extended operating temperature range to 200°C accommodates high-temperature applications. However, this part is RoHS non-compliant and does not carry AEC-Q101 automotive qualification. Selection is restricted to applications where RoHS compliance and automotive qualification are not required. Current inventory of 17,961 units supports procurement needs.

Compliance Considerations: For applications requiring automotive-grade components with AEC-Q101 qualification and RoHS3 compliance, selection is limited to Vishay General Semiconductor parts: TZMB36-GS08, TZMC36-GS08, or the original TZMC36-GS18. The CLL5258B TR TIN/LEAD does not meet these compliance requirements and is suitable only for non-automotive applications where RoHS compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can the TZMB36-GS08 replace the TZMC36-GS18 in automotive applications?

A: Yes. The TZMB36-GS08 is a direct substitute with identical electrical performance, AEC-Q101 qualification, and RoHS3 compliance. The primary difference is tighter Zener voltage tolerance (±2% versus ±5%), which improves voltage regulation accuracy without affecting functional compatibility.

Q: What is the difference between TZMC36-GS18 and TZMC36-GS08?

A: Both parts are from the Vishay TZM series with identical electrical specifications, tolerance, and compliance certifications. The designation suffix indicates different packaging configurations or tape specifications. Both are functionally equivalent for circuit design purposes.

Q: Is the CLL5258B TR TIN/LEAD suitable for automotive applications?

A: The CLL5258B TR TIN/LEAD does not carry AEC-Q101 automotive qualification and is RoHS non-compliant. This part is not suitable for automotive applications requiring these certifications. Use only in non-automotive applications where compliance requirements are not mandated.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Voltage - Zener (Nominal) at 36 V, (2) Power - Maximum at 500 mW, (3) Package / Case as SOD-80 MiniMELF, and (4) Mounting Type as Surface Mount. All substitute parts match these critical parameters.

Q: Does the CLL5258B TR TIN/LEAD have better performance characteristics than the TZMC36-GS18?

A: The CLL5258B TR TIN/LEAD exhibits lower impedance (70 Ohms versus 80 Ohms) and reduced forward voltage (1.25 V versus 1.5 V at 200 mA), resulting in improved efficiency. However, it lacks AEC-Q101 qualification and RoHS3 compliance, restricting its use to non-automotive applications.

Q: What inventory levels are available for each substitute part?

A: TZMC36-GS18: 7,628 units; TZMB36-GS08: 1,415 units; TZMC36-GS08: 50,400 units; CLL5258B TR TIN/LEAD: 17,961 units. The TZMC36-GS08 offers the highest availability for production requirements.

Q: Can I use the CLL5258B TR TIN/LEAD in place of the TZMC36-GS18 for cost reduction?

A: The CLL5258B TR TIN/LEAD is not suitable as a direct replacement for automotive applications due to lack of AEC-Q101 qualification and RoHS non-compliance. Use only in non-automotive applications where these certifications are not required. For automotive applications, use Vishay parts: TZMB36-GS08 or TZMC36-GS08.

Q: What is the operating temperature range for each substitute part?

A: TZMC36-GS18, TZMB36-GS08, and TZMC36-GS08 all operate from -65°C to 175°C. The CLL5258B TR TIN/LEAD extends to -65°C to 200°C, providing a wider temperature range for high-temperature applications.
