Engineering Selection Recommendations

TLZ36D-GS08 (Vishay General Semiconductor - Diodes Division)

Primary selection for applications requiring RoHS3 compliance. Active product status with established supply chain. Specified impedance of 75 Ohms and forward voltage of 1.5 V @ 200 mA. Operating temperature range -65°C to 175°C. Recommended for new designs and applications with RoHS3 regulatory requirements.

CLL5258B TR (Central Semiconductor Corp)

Alternative source with higher inventory availability (17,961 units). Offers lower impedance (70 Ohms) and reduced forward voltage (1.25 V @ 200 mA). Extended operating temperature range to 200°C. RoHS non-compliant status restricts use in applications with mandatory RoHS3 requirements. Suitable for legacy designs or applications without RoHS compliance mandates.

BZV55-C36,115 (Nexperia USA Inc.)

Manufacturer-recommended substitute with RoHS3 compliance. Highest inventory availability (19,043 units). Impedance of 90 Ohms and forward voltage of 900 mV @ 10 mA. Extended operating temperature range to 200°C. Recommended for applications requiring extended temperature performance and RoHS3 compliance with alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can CLL5258B TR be used as a direct replacement for TLZ36D-GS08 in RoHS3-compliant applications?

A: No. CLL5258B TR carries RoHS non-compliant status, which disqualifies it from applications with mandatory RoHS3 regulatory requirements. BZV55-C36,115 is the appropriate RoHS3-compliant substitute.

Q: What is the primary difference in impedance between these three parts?

A: TLZ36D-GS08 specifies 75 Ohms maximum impedance, CLL5258B TR specifies 70 Ohms, and BZV55-C36,115 specifies 90 Ohms. All values fall within acceptable ranges for 36 V, 500 mW Zener diodes in SOD-80 packaging.

Q: Are all three parts physically compatible with the same PCB footprint?

A: Yes. All three parts use DO-213AC, MINI-MELF, SOD-80 package specifications and surface mount mounting type, ensuring mechanical compatibility with existing PCB designs.

Q: Which substitute offers the lowest forward voltage drop?

A: BZV55-C36,115 specifies 900 mV @ 10 mA, which is lower than TLZ36D-GS08 (1.5 V @ 200 mA) and CLL5258B TR (1.25 V @ 200 mA). Note that forward voltage measurements are taken at different current levels.

Q: What is the temperature performance difference between the main part and substitutes?

A: TLZ36D-GS08 operates from -65°C to 175°C. Both CLL5258B TR and BZV55-C36,115 extend the upper limit to 200°C, providing 25°C additional high-temperature capability.

Q: Which part has the lowest reverse leakage current?

A: TLZ36D-GS08 specifies 40 nA @ 32.3 V. BZV55-C36,115 specifies 50 nA @ 25.2 V. CLL5258B TR specifies 100 nA @ 27 V. Leakage measurements are taken at different voltage points, affecting direct comparison.

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

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.
