TDZTR13 Zener Diode Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor TDZTR13 is a surface-mount Zener diode rated for 13 V, 500 mW power dissipation, and ±10% tolerance. It is supplied in a TUMD2 package and intended for general voltage regulation and reference applications. As supply chain continuity, logistical constraints, or footprint compatibility can affect procurement, a comparison with directly substitutable Zener diodes is necessary to ensure functional and regulatory equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by direct matching of core electrical characteristics and regulatory compliance. The key parameters for equivalence in Zener diodes are:

• Voltage - Zener (Nom) (Vz)
• Tolerance
• Power - Max
• Current - Reverse Leakage @ Vr
• Operating Temperature
• Mounting Type
• Package / Case
• Supplier Device Package
• RoHS and REACH Compliance
• Moisture Sensitivity Level
• ECCN/HTSUS Code

Substitute diodes listed below conform to one or more of these electrical and environmental attributes, enabling precise equivalency grouping.

Parameter Comparison

Engineering Selection Recommendations

All listed Zener diodes are in active status and comply with ROHS3, REACH unaffected status, and ECCN/HTSUS classifications matching the TDZTR13. Moisture Sensitivity Level is 1 (unlimited), ensuring compatibility with standard assembly processes. Product status is active for all models, supporting long-term availability.

Frequently Asked Questions (FAQ)

Q1: What core characteristics determine equivalency for the TDZTR13 Zener diode?
A1: Substitutability is defined by Zener voltage, tolerance, maximum power dissipation, reverse leakage current, operating temperature, mounting type, package, RoHS/REACH compliance, and comparable part status.

Q2: What package considerations are necessary when choosing an alternative for TDZTR13?
A2: The TDZTR13 uses a 2-SMD (TUMD2) surface-mount package. Substitute devices listed are also surface-mount, but may use TUMD2M or SOD-323F (SC-90). Confirm design footprint compatibility based strictly on package types provided.

Q3: Do alternative Zener diode part numbers differ in electrical performance?
A3: Substitute Zener diodes provided operate at the specified 13 V nominal voltage, with variations only in tolerance, package, or maximum power, as shown in the comparison table.

Q4: Are all substitute diodes compliant with international standards?
A4: All alternative parts are ROHS3 compliant, have MSL 1 (unlimited), and are REACH unaffected, matching the regulatory status of TDZTR13.

Q5: Is there any difference in the inventory or part status?
A5: All substitute Zener diodes listed have an active product status with inventory quantities specified. No obsolete or discontinued parts are included in this reference.
