Engineering Selection Recommendations

Both TZMB3V6-GS18 and TZMB3V6-GS08 are Active products manufactured by Vishay General Semiconductor - Diodes Division within the TZM series. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical performance differences.

The TZMB3V6-GS18 is available with 794 pieces in current inventory. The TZMB3V6-GS08 is available with 20,100 pieces in current inventory, providing greater supply availability.

Both parts carry identical certifications: AEC-Q101 automotive qualification, ROHS3 compliance, and REACH Unaffected status. Both maintain MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

For applications requiring automotive-grade Zener diodes with 3.6 V regulation at 500 mW power dissipation in SOD-80 MiniMELF surface mount packages, either part number provides equivalent electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)
