TFZGTR3.6B Equivalent & Substitute Parts Reference

Part Overview

The TFZGTR3.6B from Rohm Semiconductor is a Zener diode intended for surface mount applications, with a nominal Zener voltage of 3.6 V, a maximum power rating of 500 mW, and a TUMD2 package. It is compliant with ROHS3 and REACH, and currently has an active part status. In engineering applications, finding alternative or substitute Zener diodes is often required to address factors such as supply chain demands, inventory constraints, or product lifecycle considerations. Substitute selection must be based strictly on compliance with the main part’s critical electrical, mechanical, and regulatory parameters.

Substitute Part Grouping Explanation

Substitution for Zener diodes in this reference is determined strictly by matching the essential electrical performance parameters, mounting configuration, package size, and compliance status. The key parameters considered for direct substitution include Nominal Zener Voltage (Vz), Power Rating, Maximum Impedance (Zzt), Reverse Leakage Current, Operating Temperature Range, Surface Mount Compatibility, Physical Package Type, and RoHS/REACH compliance. Only parts matching these criteria are listed as substitutes.

Frequently Asked Questions (FAQ)

Q: What are the main parameters to consider when finding TFZGTR3.6B substitutes?
A: The primary parameters are Zener voltage (Vz), power rating, impedance (Zzt), reverse leakage current, operating temperature range, mounting type, physical package, and environmental compliance status.

Q: Can substitute Zener diodes with different package styles be used for the same application?
A: Substitute selection must match both the electrical characteristics and the mechanical package requirements of the target design. Review the mounting type and supplier device package to ensure board-level compatibility.

Q: Are all listed substitutes compliant with RoHS requirements?
A: Yes, all substitutes in this reference are specified as ROHS3 compliant.

Q: Is the power rating of the substitute parts always equal to the original?
A: Substitute power ratings are listed in the comparison table. Selection must align with the application's required power rating.

Q: Do substitute parts have the same reverse leakage and impedance?
A: The listed substitutes specify exact figures for reverse leakage and impedance, as detailed in the parameter comparison table. Only parts with these parameters stated are included as substitutes.

Q: Is information about qualification levels (e.g., automotive grade) relevant for substitution?
A: Only environmental compliance and status fields provided have been considered in this reference. Additional grading or qualification is not included unless specified among the main allowed parameters.
