Equivalent & Substitute Parts for CLL4619 BK

Part Overview

The Central Semiconductor Corp CLL4619 BK is a Zener Diode, 3 V, 500 mW, with ±5% tolerance, surface-mount SOD-80 package. The main part is currently categorized as obsolete. Due to its obsolete status, it is necessary to identify alternative Zener diode models with equivalent electrical and mechanical characteristics as specified. This ensures uninterrupted design, repair, or production activities where the original part can no longer be sourced.

Substitute Part Grouping Explanation

Substitution is strictly determined by the following key parameters: Zener voltage (3 V nominal), tolerance (±5%), maximum power dissipation (500 mW), maximum impedance (1600 Ohms), reverse leakage current (800 nA @ 1 V), maximum forward voltage (as specified), equivalent surface-mount packaging (industry standard SOD-80 or equivalent), and operating temperature range. Only parts meeting all provided values for these parameters have been included as substitutes. No additional criteria have been considered.
