TFZTR7.5B Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor TFZTR7.5B is a Zener diode categorized as Diodes, Zener, provided in Tape & Reel (TR) packaging. The device features a nominal Zener voltage of 7.26 V, a power rating of 500 mW, and a maximum impedance of 8 Ohms. It utilizes a surface mount TUMD2 package. As the TFZTR7.5B is marked "Not For New Designs," sourcing alternative models with matching electrical and mechanical parameters is necessary to ensure continued design availability, manufacturing support, and compliance with modern component sourcing requirements.

Frequently Asked Questions (FAQ)

Q: What are the most critical parameters when substituting the TFZTR7.5B Zener diode?
A: Voltage - Zener (Nom), power rating, maximum impedance, reverse leakage current, tolerance, mounting type, and package dimensions are the essential parameters.

Q: Are all listed substitutes surface-mount Zener diodes?
A: All alternatives are surface-mount devices, but package outlines and codes may differ (e.g., TUMD2, TUMD2M, SOD-323F, SC-59).

Q: How important is package compatibility for substitution?
A: The mounting and mechanical package must be compatible to ensure fit and function within the existing PCB layout.

Q: Do all substitutes hold the same RoHS and REACH environmental statuses?
A: All Rohm Semiconductor and Nexperia USA Inc. BZX84J-C7V5,115 variants are RoHS3 compliant and REACH unaffected as provided.

Q: Is tolerance significant for Zener diodes in these applications?
A: Tolerance impacts precise voltage regulation. Only substitutes with matching or specified tolerance are considered equivalent per provided data.

Q: Are operational temperature ranges comparable between original and substitutes?
A: All listed substitutes provide a maximum operating temperature up to 150°C or higher, matching the original TFZTR7.5B rating.
