Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly governed by matching the following key parameters: Zener voltage (Vz), maximum power dissipation, maximum Zener impedance (Zzt), maximum forward voltage at stated test current, operating temperature range, mounting type, package/case, compliance certifications (RoHS, REACH), moisture sensitivity level (MSL), and relevant automotive qualification. Substitute parts must match or exceed all provided parameters for functional compatibility within the same category and intended application.

Parameter Comparison

Engineering Selection Recommendations

The VLZ3V9-GS08 has an obsolete product status. The TLZ3V9-GS08 is classified as active and meets all compliance ratings including RoHS3 and REACH. Both parts have automotive grade qualification and identical electrical performance and mounting type. Substitute selection is based on equivalency in product status, environmental compliance, automotive qualification, and matching package characteristics as specified.
