Key Parameters

Substitute Part Grouping Explanation

Substitution for Zener diodes such as the TLZ20C-GS18 is determined strictly by matching the following key parameters: Zener voltage (Vz), maximum power dissipation, impedance (Zzt), reverse leakage current, maximum forward voltage, operating temperature range, mounting type, and package/case. All listed substitute parts are Zener diodes, share the 20 V Zener voltage, a 500 mW maximum power rating, and utilize the DO-213AC, MINI-MELF, SOD-80 surface mount package. Compliance with RoHS3 and REACH regulations and equivalent MSL ratings further validate their use as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both TLZ20C-GS18 and its substitute CLL5250B TR PBFREE are active, ROHS3 compliant, REACH unaffected, and have unlimited moisture sensitivity levels. These attributes meet standard requirements for use in RoHS and REACH-compliant electronic manufacturing processes.
