Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLZ10D-GS18 is determined by the following critical parameters:

Primary Substitution Criteria:

• Nominal zener voltage of 10 V
• Maximum power dissipation of 500 mW
• Surface mount package type (SOD-80 MiniMELF / DO-213AC)
• Operating temperature range compatibility
• ROHS3 compliance and MSL 1 rating

Secondary Compatibility Factors:

• Zener voltage tolerance (±5% acceptable for most applications)
• Forward voltage characteristics
• Reverse leakage current specifications
• Impedance parameters

The substitute part CLL5240B TR PBFREE meets all primary substitution criteria and maintains functional equivalence within the specified electrical and mechanical parameters.

Engineering Selection Recommendations

TLZ10D-GS18 (Vishay):

• Primary choice for applications requiring lower impedance (8 Ohms maximum)
• Preferred for circuits with strict reverse leakage current specifications (40 nA @ 9.44 V)
• Suitable for operating environments up to 175°C
• Active product status with established supply chain

CLL5240B TR PBFREE (Central Semiconductor):

• Direct functional substitute with identical nominal zener voltage and power rating
• Extended operating temperature range to 200°C provides thermal margin
• Lower forward voltage drop (1.25 V vs. 1.5 V @ 200 mA) reduces power dissipation in forward-biased conditions
• Higher impedance (17 Ohms) acceptable for applications with less stringent impedance requirements
• ROHS3 and REACH compliant with MSL 1 rating
• Higher inventory availability (11,718 pcs vs. 989 pcs)

Both parts are active-status products with full regulatory compliance. Selection between these parts depends on specific circuit requirements regarding impedance, reverse leakage current, and operating temperature limits.

Frequently Asked Questions (FAQ)

Q: Can CLL5240B TR PBFREE be used as a direct replacement for TLZ10D-GS18?

A: Yes. Both parts share identical nominal zener voltage (10 V), maximum power dissipation (500 mW), and surface mount SOD-80 packaging. Both are ROHS3 compliant with MSL 1 rating. Electrical parameter differences (impedance, reverse leakage, forward voltage) are within acceptable ranges for most voltage regulation and protection applications.

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

A: The TLZ10D-GS18 has lower impedance (8 Ohms vs. 17 Ohms) and lower reverse leakage current (40 nA vs. 3 µA). The CLL5240B TR PBFREE has lower forward voltage drop (1.25 V vs. 1.5 V @ 200 mA) and extended operating temperature range (-65 to 200°C vs. -65 to 175°C).

Q: Are the packages physically identical?

A: Yes. Both parts use DO-213AC, MINI-MELF, SOD-80 surface mount packaging. PCB footprints and reflow soldering profiles are compatible.

Q: Which part should be selected for high-temperature applications?

A: The CLL5240B TR PBFREE supports operation up to 200°C, providing 25°C additional thermal margin compared to the TLZ10D-GS18 (175°C maximum).

Q: Does the impedance difference affect circuit performance?

A: Impedance differences (8 Ohms vs. 17 Ohms) affect voltage regulation characteristics under dynamic load conditions. Applications with strict impedance requirements should use the TLZ10D-GS18. General voltage regulation and protection circuits tolerate the higher impedance of the CLL5240B TR PBFREE.

Q: Are both parts lead-free?

A: Yes. Both parts are ROHS3 compliant and lead-free. The CLL5240B TR PBFREE designation explicitly indicates lead-free construction.

Q: What is the tolerance difference?

A: The TLZ10D-GS18 does not specify zener voltage tolerance in the provided data. The CLL5240B TR PBFREE specifies ±5% tolerance, which is standard for zener diodes in this voltage and power class.
