2M22Z A0G Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M22Z A0G is an active zener diode manufactured by Taiwan Semiconductor Corporation, rated for 22 V nominal zener voltage with 2 W maximum power dissipation. This component is packaged in the DO-204AC (DO-15) axial through-hole configuration and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist, enabling component selection flexibility for circuit design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M22Z A0G is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage (Vz) must be 22 V nominal with ±5% tolerance
• Reverse leakage current must not exceed 500 nA @ 16.7 V
• Package and case must be DO-204AC or DO-15 axial configuration

Mechanical Compatibility Criteria:

• Through-hole mounting type required
• Axial lead configuration for PCB insertion

Compliance Requirements:

• ROHS3 compliance mandatory
• MSL rating of 1 (Unlimited) acceptable

The substitute part 1N5358B-TP meets these criteria with identical zener voltage, tolerance, reverse leakage specification, and package configuration. The 1N5358B-TP provides higher power rating (5 W versus 2 W) and lower impedance (3.5 Ohms versus 12 Ohms), making it suitable for applications requiring enhanced thermal performance within the same voltage class.

Engineering Selection Recommendations

2M22Z A0G Selection: Use the 2M22Z A0G when the application requires a 22 V zener diode with 2 W maximum power dissipation and extended operating temperature range to 175°C. This part is active and ROHS3 compliant with unlimited moisture sensitivity rating.

1N5358B-TP Selection: Use the 1N5358B-TP as a substitute when higher power dissipation capacity (5 W) is required within the same 22 V zener voltage class. The 1N5358B-TP provides lower impedance (3.5 Ohms) for improved voltage regulation performance. This part is active and ROHS3 compliant with unlimited moisture sensitivity rating. Operating temperature range is -55°C to 150°C.

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0050.

Frequently Asked Questions (FAQ)

Q: Can the 1N5358B-TP directly replace the 2M22Z A0G in all applications?

A: The 1N5358B-TP is electrically compatible for 22 V zener voltage regulation. However, verify that the application does not require the extended upper operating temperature of 175°C, as the 1N5358B-TP operates to 150°C maximum. The higher power rating and lower impedance of the 1N5358B-TP are compatible with circuits designed for the 2M22Z A0G.

Q: What is the significance of the impedance difference between these parts?

A: The 1N5358B-TP has lower impedance (3.5 Ohms) compared to the 2M22Z A0G (12 Ohms). Lower impedance provides better voltage regulation stability and reduced output impedance in zener regulation circuits. This is a beneficial characteristic for substitution.

Q: Are the package configurations identical?

A: Both parts use the DO-204AC (DO-15) axial through-hole package configuration. Physical dimensions and lead spacing are compatible for direct PCB mounting without layout modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 2M22Z A0G and 1N5358B-TP are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). Both are classified under ECCN EAR99.

Q: What is the reverse leakage current specification?

A: Both parts specify 500 nA maximum reverse leakage current at 16.7 V reverse voltage. This parameter is identical and ensures equivalent leakage performance in circuit applications.

Q: Can the 2M22Z A0G be used in place of the 1N5358B-TP?

A: The 2M22Z A0G can substitute for the 1N5358B-TP in applications where 2 W power dissipation is sufficient. The lower power rating of the 2M22Z A0G may limit use in high-current zener regulation circuits. Verify thermal requirements before substitution.
