TZMC5V6-M-08 Equivalent & Substitute Parts

Part Overview

The TZMC5V6-M-08 is a Zener diode rated at 5.6 V nominal with 500 mW power dissipation, manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component in SOD-80 MiniMELF package is designed for voltage regulation and protection applications. The part is Active status and carries AEC-Q101 automotive qualification with ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging format preferences, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: nominal Zener voltage (5.6 V), maximum power dissipation (500 mW), surface mount technology, and operating temperature range (-65°C to 175°C). Tolerance variations are permitted within design margins. Package format compatibility (SOD-80 MiniMELF or equivalent mechanical footprint) is required for direct board-level substitution. Automotive grade and AEC-Q101 qualification are maintained across primary substitute options. Secondary substitutes from alternative manufacturers may exhibit different impedance characteristics and reverse leakage specifications while maintaining core voltage and power ratings.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Vishay TZM Series): TZMB5V6-GS08 and TZMB5V6-GS18 are direct parametric equivalents from the same manufacturer. Both maintain 5.6 V nominal voltage, 500 mW power rating, SOD-80 MiniMELF package, automotive grade, and AEC-Q101 qualification. The TZMB variants offer improved tolerance specification (±2% versus ±5%), identical impedance and leakage characteristics, and equivalent forward voltage performance. Packaging format differs (Cut Tape & Digi-Reel versus Tape & Reel for GS08; Cut Tape for GS18), accommodating different procurement and assembly workflows.

Secondary Substitutes (Microchip): The 1N4626UR-1 maintains 5.6 V nominal voltage and 500 mW power rating with matching operating temperature range. However, this part uses DO-213AA package instead of SOD-80 MiniMELF, requiring PCB footprint verification. Impedance is significantly higher (1400 Ohms), and reverse leakage is elevated (5 µA @ 4 V). This part lacks automotive grade and AEC-Q101 qualification. The 1N5231BUR-1 operates at 5.1 V nominal voltage, which deviates from the 5.6 V specification. This part is RoHS non-compliant and lacks automotive qualification. Both Microchip parts are suitable only when voltage tolerance and package constraints permit deviation from the primary specification.

Frequently Asked Questions (FAQ)

Q: Can TZMB5V6-GS08 and TZMB5V6-GS18 be used interchangeably with TZMC5V6-M-08?

A: Yes. Both TZMB variants are parametric equivalents with identical electrical performance in the critical parameters: 5.6 V nominal voltage, 500 mW power, 40 Ohms impedance, 100 nA reverse leakage, and 1.5 V forward voltage. All three parts share SOD-80 MiniMELF package, automotive grade, and AEC-Q101 qualification. The primary difference is packaging format (tape reel configuration), which does not affect electrical function.

Q: What is the difference between TZMB5V6-GS08 and TZMB5V6-GS18?

A: Both parts are electrically identical with 5.6 V nominal voltage and 500 mW power rating. The difference is packaging: TZMB5V6-GS08 is supplied in Cut Tape & Digi-Reel format, while TZMB5V6-GS18 is supplied in Cut Tape format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Can Microchip 1N4626UR-1 replace TZMC5V6-M-08 directly?

A: Electrical substitution is possible because both parts maintain 5.6 V nominal voltage and 500 mW power rating. However, package compatibility must be verified: 1N4626UR-1 uses DO-213AA case while TZMC5V6-M-08 uses SOD-80 MiniMELF. PCB footprint differences require design review. Additionally, 1N4626UR-1 lacks automotive grade and AEC-Q101 qualification, making it unsuitable for automotive applications.

Q: Why is 1N5231BUR-1 listed as a substitute if the voltage is different?

A: The 1N5231BUR-1 is provided as a reference option only. Its 5.1 V nominal voltage deviates from the 5.6 V specification of TZMC5V6-M-08. This part is not a direct substitute and is suitable only in applications where 5.1 V operation is acceptable. Additionally, this part is RoHS non-compliant and lacks automotive qualification.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: nominal Zener voltage (5.6 V), maximum power dissipation (500 mW), operating temperature range (-65°C to 175°C), and surface mount technology. Package format (SOD-80 MiniMELF or equivalent footprint) must be compatible with PCB design. For automotive applications, AEC-Q101 qualification and automotive grade are required.

Q: Are all substitute parts RoHS compliant?

A: TZMC5V6-M-08, TZMB5V6-GS08, TZMB5V6-GS18, and 1N4626UR-1 are ROHS3 compliant. The 1N5231BUR-1 is RoHS non-compliant and must not be used in applications requiring RoHS compliance.

Q: What is the tolerance difference between TZMC5V6-M-08 and TZMB5V6 variants?

A: TZMC5V6-M-08 has ±5% tolerance on the 5.6 V nominal voltage. TZMB5V6-GS08 and TZMB5V6-GS18 have tighter ±2% tolerance. Both tolerances are acceptable for most voltage regulation applications; the TZMB variants provide improved voltage accuracy.
