MM5Z2V4T5G Equivalent & Substitute Parts

Part Overview

The MM5Z2V4T5G is an active zener diode manufactured by onsemi, designed for voltage regulation and protection applications. This surface mount component operates at a nominal zener voltage of 2.4 V with a maximum power dissipation of 500 mW in the SOD-523 package. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial and commercial applications across a wide temperature range of -65°C to 150°C.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support component procurement strategies while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM5Z2V4T5G is determined by strict equivalence across all critical electrical parameters: nominal zener voltage (2.4 V), voltage tolerance (±8.33%), maximum power dissipation (500 mW), maximum impedance (100 Ohms), reverse leakage current (50 µA @ 1 V), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C to 150°C). The package type must remain SC-79/SOD-523 surface mount configuration to ensure mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Substitute parts must maintain identical compliance certifications including ROHS3 status and REACH unaffected classification. Packaging format variations (Cut Tape, Digi-Reel, or Tape & Reel) do not affect electrical or mechanical substitution eligibility, as these represent distribution and handling formats only.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts should be based on packaging format requirements and supply chain availability. The MM5Z2V4T5G is available in standard packaging, while the SZMM5Z2V4T5G is offered in Cut Tape (CT) and Digi-Reel formats, providing flexibility for different procurement and assembly workflows. Both parts maintain active product status with onsemi and are ROHS3 compliant with unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can SZMM5Z2V4T5G replace MM5Z2V4T5G in existing designs?

A: Yes. The SZMM5Z2V4T5G is a direct parametric equivalent with identical electrical specifications, voltage rating, power dissipation, impedance, leakage current, forward voltage, and operating temperature range. Both components use the same SC-79/SOD-523 surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts.

Q: What is the difference between MM5Z2V4T5G and SZMM5Z2V4T5G?

A: The primary difference is packaging format and automotive qualification. The SZMM5Z2V4T5G includes AEC-Q101 automotive qualification and is supplied in Cut Tape (CT) and Digi-Reel formats, while the MM5Z2V4T5G uses standard packaging. All electrical and mechanical parameters are identical.

Q: Are packaging format variations (Cut Tape, Digi-Reel, Tape & Reel) considered substitutions?

A: No. Packaging format variations represent distribution and handling methods only and do not affect electrical or mechanical substitution eligibility. Components with identical electrical specifications and the same physical package type are considered equivalent regardless of packaging format.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both MM5Z2V4T5G and SZMM5Z2V4T5G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. The SZMM5Z2V4T5G additionally carries AEC-Q101 automotive qualification.

Q: What parameters must remain identical for substitution?

A: Zener voltage (2.4 V), voltage tolerance (±8.33%), maximum power dissipation (500 mW), maximum impedance (100 Ohms), reverse leakage current (50 µA @ 1 V), forward voltage (900 mV @ 10 mA), operating temperature range (-65°C to 150°C), and package type (SC-79/SOD-523 surface mount) must all remain identical for direct substitution.

Q: Can I use a different zener voltage rating as a substitute?

A: No. The nominal zener voltage of 2.4 V is a critical parameter for voltage regulation and protection functions. Substitutes must maintain the identical 2.4 V rating and ±8.33% tolerance specification.
