MM5Z8V2T5G Equivalent & Substitute Parts

Part Overview

The MM5Z8V2T5G is an active production Zener diode manufactured by onsemi, designed for voltage regulation and protection applications in surface mount configurations. This 8.2 V, 500 mW Zener diode operates across an industrial temperature range of -65°C to 150°C and is packaged in the SC-79/SOD-523 form factor. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when specific packaging or qualification requirements necessitate alternative sourcing.

Substitute Part Grouping Explanation

Substitution of the MM5Z8V2T5G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SZMM5Z8V2T5G maintains identical specifications for Zener voltage (8.2 V), tolerance (±6.1%), maximum power dissipation (500 mW), impedance (15 Ohms maximum), reverse leakage current (700 nA @ 5 V), forward voltage (900 mV @ 10 mA maximum), and operating temperature range (-65°C to 150°C). Both parts are packaged in the SC-79/SOD-523 surface mount configuration and comply with ROHS3 and REACH requirements.

The primary distinction between the main part and its substitute is packaging format and automotive qualification. The MM5Z8V2T5G is supplied in standard packaging, while SZMM5Z8V2T5G is supplied in Tape & Reel (TR) format and carries AEC-Q101 automotive qualification. This distinction does not affect electrical performance or functional compatibility; it reflects supply chain configuration and application-specific certification requirements.

Key Parameters Determining Substitution:

• Zener voltage: 8.2 V
• Power rating: 500 mW
• Impedance: 15 Ohms maximum
• Package type: SOD-523
• Mounting: Surface Mount
• Temperature range: -65°C to 150°C
• Compliance: ROHS3, REACH Unaffected

Parameter Comparison

Engineering Selection Recommendations

Both MM5Z8V2T5G and SZMM5Z8V2T5G are active production parts from onsemi with identical electrical and thermal specifications. Selection between these parts is determined by supply chain and application requirements rather than functional performance.

MM5Z8V2T5G is appropriate for standard industrial and commercial applications where packaging format is not constrained to Tape & Reel configuration and automotive qualification is not required.

SZMM5Z8V2T5G is appropriate for applications requiring Tape & Reel packaging for automated assembly processes and for designs targeting automotive applications where AEC-Q101 qualification is specified or preferred. The AEC-Q101 qualification indicates compliance with automotive reliability and quality standards.

Both parts maintain full compliance with ROHS3 and REACH requirements. The unlimited moisture sensitivity rating (MSL 1) indicates no special storage or handling requirements for either part. Selection should be based on procurement availability, packaging requirements for manufacturing processes, and application-specific qualification mandates.

Frequently Asked Questions (FAQ)

Q: Can SZMM5Z8V2T5G be used as a direct replacement for MM5Z8V2T5G in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The primary difference is packaging format (Tape & Reel versus standard) and automotive qualification status. Direct substitution is valid from an electrical and functional standpoint. Verify that your assembly process can accommodate the packaging format of the substitute part.

Q: What does AEC-Q101 qualification mean for the SZMM5Z8V2T5G?

A: AEC-Q101 is an automotive industry standard qualification that certifies the part meets specific reliability, quality, and testing requirements for automotive applications. This qualification does not alter the electrical specifications but indicates the part has undergone additional validation testing. Use SZMM5Z8V2T5G when automotive-grade components are specified or required by design standards.

Q: Are there any temperature or power rating differences between these parts?

A: No. Both parts operate across the identical temperature range (-65°C to 150°C) and have the same maximum power dissipation (500 mW). All thermal and electrical characteristics are equivalent.

Q: What is the significance of the Tape & Reel packaging for SZMM5Z8V2T5G?

A: Tape & Reel (TR) packaging is a standard format for high-volume automated assembly processes. Components are wound on a continuous tape and reel, enabling direct feeding into pick-and-place equipment. If your manufacturing process uses automated assembly, Tape & Reel packaging may be preferred or required. Standard packaging is suitable for manual assembly or lower-volume production.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. No special storage, handling, or baking procedures are required prior to assembly for either part.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No regulatory or compliance differences exist between the two parts. The AEC-Q101 qualification on SZMM5Z8V2T5G is an additional certification, not a replacement for standard compliance.

Q: What is the impedance specification and why does it matter?

A: The maximum impedance of 15 Ohms is a dynamic impedance parameter that affects the Zener diode's voltage regulation characteristics at different operating currents. Both parts maintain identical impedance specifications, ensuring equivalent performance in voltage regulation and protection circuits.
