Key Parameters

Substitute Part Grouping Explanation

Substitute selection for Zener diodes in the DO-213AC, MINI-MELF, SOD-80 surface-mount package must match the following parameters: nominal Zener voltage, maximum power dissipation, impedance, forward voltage at the specified current, operating temperature range, mounting type, and compliance statuses. Only parts that align with these key parameters are included in the equivalent and substitute reference list.

Parameter Comparison

Engineering Selection Recommendations

Both TLZ22-GS18 and CLL5251B TR PBFREE are active and ROHS3 compliant Zener diodes in the DO-213AC, MINI-MELF, SOD-80 package for surface-mount applications. Both have an MSL of 1 (unlimited) and are REACH unaffected. Either part may be selected based strictly on these statuses for substitute or equivalent use where compliance and supply continuity are required.
