MMFZ8V2T1G Zener Diode Equivalent & Substitute Parts

Part Overview

The MMFZ8V2T1G is a Zener diode rated at 8.2 V nominal voltage with 500 mW maximum power dissipation in a Surface Mount SOD-123 package, manufactured by onsemi. This part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

The MMFZ8V2T1G shares the same core electrical specifications with active alternatives in the onsemi product line. Substitution is necessary due to the obsolete status of the original part number, which may result in limited availability and extended lead times. Active equivalents maintain identical voltage ratings, power ratings, and package configurations while offering improved supply chain accessibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMFZ8V2T1G is based on the following critical parameters that must remain constant across equivalent components:

Electrical Parameters:

• Zener voltage: 8.2 V nominal
• Maximum power dissipation: 500 mW
• Package type: SOD-123 (Surface Mount)

Physical Parameters:

• Mounting configuration: Surface Mount
• Moisture sensitivity classification: MSL 1 (Unlimited)

The substitute part MMSZ8V2T1G meets all these criteria while maintaining active product status within the onsemi catalog. Both parts are manufactured to the same base product specifications and are functionally interchangeable in circuit applications requiring 8.2 V Zener regulation at 500 mW power levels.
