TZMA10-GS08 Equivalent & Substitute Parts

Part Overview

The TZMA10-GS08 is an active zener diode manufactured by Vishay General Semiconductor - Diodes Division, designed for voltage regulation and protection applications. This surface mount component operates at a nominal zener voltage of 10 V with a maximum power dissipation of 500 mW in a compact SOD-80 MiniMELF package. The part is RoHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to address inventory availability, packaging preferences, or specific application requirements while maintaining electrical compatibility within defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TZMA10-GS08 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Nominal zener voltage of 10 V
• Maximum power dissipation of 500 mW
• Surface mount configuration
• Operating temperature range of -65°C to 175°C
• Reverse leakage current characteristics
• Forward voltage characteristics

The 1N4104UR-1 qualifies as a manufacturer-recommended substitute based on matching nominal zener voltage (10 V), maximum power rating (500 mW), operating temperature range (-65°C to 175°C), and surface mount technology. Both components function as voltage regulation and protection devices in equivalent circuit applications. Differences in impedance, reverse leakage current, forward voltage, and package designation (DO-213AA versus SOD-80) are within acceptable tolerances for standard zener diode applications.

Engineering Selection Recommendations

TZMA10-GS08 Selection: Select the TZMA10-GS08 when RoHS3 compliance is a mandatory requirement for the end application or final assembly location. This part maintains active product status and full regulatory compliance across RoHS3 and REACH standards. The SOD-80 MiniMELF package offers compact form factor with specified impedance characteristics of 15 Ohms maximum.

1N4104UR-1 Selection: The 1N4104UR-1 serves as a functional substitute when RoHS compliance is not required and inventory availability of the primary part is constrained. This part maintains active product status and equivalent electrical performance for 10 V zener regulation at 500 mW power dissipation. The DO-213AA package provides mechanical compatibility with standard surface mount assembly processes. Note that this substitute does not meet RoHS3 compliance requirements.

Application Considerations: Both parts operate across the identical temperature range (-65°C to 175°C) and provide unlimited moisture sensitivity rating (MSL 1). Selection between these parts depends on regulatory compliance mandates and package footprint requirements specific to the circuit board design. The electrical parameter differences (impedance, reverse leakage, forward voltage) fall within acceptable ranges for standard voltage regulation and transient protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 1N4104UR-1 directly replace the TZMA10-GS08 in all applications?

A: The 1N4104UR-1 provides electrical substitution for 10 V zener voltage regulation and 500 mW power dissipation applications. However, the substitute part is RoHS non-compliant, whereas the TZMA10-GS08 is RoHS3 compliant. Applications subject to RoHS3 regulatory requirements must use the TZMA10-GS08. Package footprints differ (SOD-80 versus DO-213AA), requiring verification of PCB layout compatibility.

Q: What are the impedance differences between these parts?

A: The TZMA10-GS08 specifies maximum impedance of 15 Ohms, while the 1N4104UR-1 specifies 200 Ohms maximum. Lower impedance in the TZMA10-GS08 provides improved voltage regulation characteristics and faster transient response. Applications requiring tighter voltage regulation should prioritize the TZMA10-GS08.

Q: Are the package designations DO-213AA and SOD-80 mechanically compatible?

A: DO-213AA and SOD-80 are distinct package designations for surface mount diodes. While both are miniature surface mount packages, they have different physical dimensions and land patterns. PCB layout and assembly equipment compatibility must be verified before substitution.

Q: What is the significance of the reverse leakage current difference?

A: The TZMA10-GS08 exhibits 100 nA reverse leakage at 7.5 V, while the 1N4104UR-1 exhibits 500 nA at 7.6 V. Lower reverse leakage in the TZMA10-GS08 results in reduced standby current consumption and improved circuit efficiency. Applications with strict power budget requirements should consider this parameter.

Q: Does the forward voltage difference affect circuit performance?

A: The TZMA10-GS08 specifies maximum forward voltage of 1.5 V at 200 mA, while the 1N4104UR-1 specifies 1.1 V at 200 mA. The lower forward voltage of the substitute part results in reduced power dissipation during forward conduction. This difference is typically negligible in voltage regulation applications but may be significant in high-current switching circuits.

Q: What is the inventory status of these parts?

A: The TZMA10-GS08 has 1058 pieces in stock as new original inventory. The 1N4104UR-1 has 910 pieces in stock as new original inventory. Both parts maintain active product status with established supply chains.
