2M15Z A0G Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M15Z A0G is a 15 V, 2 W Zener diode manufactured by Taiwan Semiconductor Corporation in the DO-204AC (DO-15) axial through-hole package. This component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Zener diodes of this specification are used in voltage regulation, overvoltage protection, and reference voltage applications in electronic circuits. Substitute parts may be required due to inventory availability, lead time constraints, or application-specific performance requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M15Z A0G is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Zener voltage (Vz) nominal value: 15 V
• Voltage tolerance: ±5%
• Package type: DO-204AC / DO-15 axial through-hole configuration
• Mounting type: Through-hole
• RoHS3 compliance status
• Operating temperature range compatibility

Secondary Compatibility Parameters:

• Power dissipation rating (equal or greater than 2 W)
• Impedance characteristics (Zzt)
• Reverse leakage current specifications
• REACH and ECCN compliance status

The substitute parts listed below maintain electrical compatibility within the specified tolerance band and mechanical interchangeability in the DO-15 package format. Substitutes with higher power ratings (5 W) remain functionally compatible for applications designed for the 2 W specification, as they operate within the same voltage and tolerance parameters while providing additional thermal margin.

Engineering Selection Recommendations

1N5352B-TP Selection Criteria: The 1N5352B-TP maintains exact nominal Zener voltage (15 V) and tolerance (±5%) matching with the 2M15Z A0G. This part is manufactured by Micro Commercial Co and carries ROHS3 compliance with REACH unaffected status. The 5 W power rating provides increased thermal capacity compared to the 2 W specification of the main part. The lower impedance (2.5 Ohms versus 7 Ohms) results in improved voltage regulation characteristics. Operating temperature range is -55°C to 150°C, which is 25°C lower than the main part at the upper limit. This part is suitable for direct substitution in applications where the reduced upper temperature limit does not conflict with system requirements.

1N5353B-TP Selection Criteria: The 1N5353B-TP differs from the 2M15Z A0G in nominal Zener voltage (16 V versus 15 V). Within the ±5% tolerance band, the 1N5353B-TP operates at a higher voltage point. This part is manufactured by Micro Commercial Co with ROHS3 compliance and REACH unaffected status. The 5 W power rating and 2.5 Ohms impedance provide enhanced performance characteristics. Operating temperature range is -55°C to 150°C. This part is suitable for substitution only in applications where a 16 V nominal reference voltage is acceptable within the circuit design tolerance.

Compliance and Regulatory Status: All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original 2M15Z A0G specification.

Frequently Asked Questions (FAQ)

Q: Can the 1N5352B-TP directly replace the 2M15Z A0G in all applications?

A: The 1N5352B-TP maintains identical nominal Zener voltage (15 V) and tolerance (±5%), with compatible DO-15 axial through-hole packaging. The primary consideration is the reduced upper operating temperature limit (150°C versus 175°C). Direct substitution is valid for applications operating within the -55°C to 150°C temperature range.

Q: What is the difference between the 1N5352B-TP and 1N5353B-TP?

A: The 1N5352B-TP has a nominal Zener voltage of 15 V, matching the 2M15Z A0G. The 1N5353B-TP has a nominal Zener voltage of 16 V. Both parts share identical tolerance (±5%), power rating (5 W), impedance (2.5 Ohms), and package format (DO-15). Selection between these parts depends on whether the application requires a 15 V or 16 V reference voltage.

Q: Are the substitute parts mechanically compatible with the original part?

A: Yes. All listed substitute parts use the DO-204AC / DO-15 axial through-hole package format, ensuring mechanical interchangeability in PCB layouts and through-hole mounting applications designed for the 2M15Z A0G.

Q: Why do the substitute parts have higher power ratings (5 W versus 2 W)?

A: Higher power ratings indicate greater thermal dissipation capacity. A 5 W rated Zener diode can safely operate in the same circuit as a 2 W rated part without exceeding its power dissipation limits. The higher rating provides additional design margin and thermal stability.

Q: What does the impedance difference mean for circuit performance?

A: Impedance (Zzt) affects voltage regulation quality. The 1N5352B-TP and 1N5353B-TP have lower impedance (2.5 Ohms) compared to the 2M15Z A0G (7 Ohms). Lower impedance results in better voltage regulation and reduced output impedance variation across the operating current range.

Q: Are there temperature range limitations when substituting parts?

A: The 2M15Z A0G operates from -55°C to 175°C. The substitute parts (1N5352B-TP and 1N5353B-TP) operate from -55°C to 150°C. Applications requiring operation above 150°C must use the original 2M15Z A0G or identify alternative parts with extended upper temperature specifications.

Q: Do all parts meet the same regulatory compliance standards?

A: Yes. The 2M15Z A0G and both substitute parts (1N5352B-TP and 1N5353B-TP) are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory status for procurement and deployment in regulated industries.
