TFZGTR20B Equivalent & Substitute Zener Diode Parts Reference

Part Overview

The TFZGTR20B from Rohm Semiconductor is a 20V Zener diode in the TUMD2 surface-mount package, supporting a maximum power dissipation of 500mW. This component is classified under the Diodes, Zener category, with a part status of "Active" and is part of Rohm's TFZGTR20 series. Finding alternative or equivalent parts is required to address supply chain requirements, multisource approvals, or specific application needs when the primary part is unavailable or design flexibility is needed.

Key Parameters

Substitute Part Grouping Explanation

Substitute zener diode parts are grouped exclusively by the following key parameters present in the input: Zener voltage (Vz), power rating (Pmax), mounting type, package, and compliance attributes (RoHS, MSL, ECCN, HTSUS). Substitution is determined strictly when these fields correspond between the main part and candidate substitutes.

Parameter Comparison

Engineering Selection Recommendations

When selecting substitutes for TFZGTR20B, prioritize parts with an active product status to ensure continued manufacturability and supply availability. All parts listed are ROHS3 compliant and possess a Moisture Sensitivity Level (MSL) of 1 (Unlimited), meeting environmental and handling requirements. Only use parts designated as "Active" for new designs. The obsolete status of PZU20B1,115 restricts its use in designs requiring ongoing sourcing. All components share common international trade classifications (ECCN EAR99, HTSUS 8541.10.0050).

Frequently Asked Questions (FAQ)

Q: What are the critical criteria for zener diode substitution in this context?
A: Substitution requires identical Zener voltage rating, compatible or higher power rating, surface-mount package compatibility, and matching environmental compliance standards.

Q: Are package types interchangeable between these substitute parts?
A: Substitute parts use different surface-mount packages (TUMD2, TUMD2M, SC-90/SOD-323F). Mechanical compatibility with the PCB footprint must be confirmed against the package specified in the provided parameters.

Q: Is there a difference in RoHS or MSL status among these parts?
A: All substitute and main parts are ROHS3 compliant and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited).

Q: Can obsolete substitute parts be used in all design scenarios?
A: The obsolete status of PZU20B1,115 limits its appropriateness for use in applications that require ongoing availability. Active status parts should be chosen for new or long-term production requirements.

Q: Is there any difference in power ratings among the substitutes?
A: Power ratings among substitutes vary: 310 mW (PZU20B1,115), 500 mW (TFZGTR20B, TFZVTR20B), and 550 mW (BZX84J-C20,115). Ensure the lower power limit is not exceeded for the substitute in your application.
