TLZ33C-GS08 Equivalent & Substitute Parts Reference

Part Overview

The TLZ33C-GS08 is a Vishay General Semiconductor Zener diode designed for surface mount applications in a SOD-80 (DO-213AC, MiniMELF) package. With nominal Zener voltage (Vz) of 33 V and a maximum power dissipation of 500 mW, it is suitable for precision voltage regulation and protection circuits. The part is active and RoHS3 compliant. As component shortages or supply chain disruptions may require alternatives, it is essential to identify substitute Zener diodes with equivalent electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected based strictly on direct parameter equivalence in Zener voltage, power rating, mechanical package, mounting type, compliance (RoHS, REACH), and electrical characteristics. The following parameters define substitution validity: Voltage - Zener (Nom) (Vz), Power - Max, Impedance (Max) (Zzt), Current - Reverse Leakage @ Vr, Voltage - Forward (Vf) (Max) @ If, Operating Temperature, Mounting Type, Package / Case, RoHS Status, Moisture Sensitivity Level, REACH Status, ECCN, and HTSUS.

Parameter Comparison

Engineering Selection Recommendations
