2M36Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M36Z is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 36 V nominal Zener voltage with 2 W maximum power dissipation. This component is packaged in DO-204AC (DO-15) axial through-hole configuration and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design optimization, or application-specific power handling requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M36Z with the 1N5365B-TP is permissible based on the following electrical and mechanical criteria:

Matching Parameters:

• Zener voltage (Nom): Both rated at 36 V
• Voltage tolerance: Both ±5%
• Reverse leakage current: Both 500 nA @ 27.4 V
• Package type: Both DO-15 axial through-hole
• RoHS compliance: Both ROHS3 compliant
• Regulatory status: Both REACH unaffected, EAR99 classification

Differing Parameters:

• Power rating: 1N5365B-TP rated 5 W (higher than 2M36Z at 2 W)
• Impedance: 1N5365B-TP 11 Ohms (lower than 2M36Z at 25 Ohms)
• Operating temperature upper limit: 1N5365B-TP 150°C (lower than 2M36Z at 175°C)

The 1N5365B-TP functions as a direct substitute where higher power dissipation capability and lower impedance are acceptable or beneficial. The reduced upper operating temperature limit does not restrict substitution in applications operating within the 1N5365B-TP range.

Engineering Selection Recommendations

Primary Part (2M36Z): Select the 2M36Z when the application requires the specified 2 W power rating, 25 Ohm maximum impedance, and extended upper operating temperature to 175°C. This part is active-status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute Part (1N5365B-TP): Select the 1N5365B-TP when higher power dissipation (5 W) is required or when lower impedance (11 Ohms) provides circuit performance benefits. This part is active-status with full ROHS3 compliance. The operating temperature upper limit of 150°C is suitable for applications not requiring the extended 175°C capability of the primary part. Both parts maintain identical Zener voltage, tolerance, and reverse leakage specifications.

Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the 1N5365B-TP replace the 2M36Z in all applications?

A: The 1N5365B-TP is electrically compatible for Zener voltage, tolerance, and reverse leakage specifications. Substitution is valid when the application operating temperature does not exceed 150°C and when the higher power rating (5 W) and lower impedance (11 Ohms) do not create circuit performance issues. Applications requiring operation above 150°C or specifically designed for 2 W power handling require the 2M36Z.

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

A: The 1N5365B-TP impedance of 11 Ohms is lower than the 2M36Z impedance of 25 Ohms. Lower impedance results in improved voltage regulation and reduced output impedance under load transients. This difference is beneficial in most applications but must be evaluated if the circuit design is optimized for the 25 Ohm characteristic of the 2M36Z.

Q: Are both parts mechanically compatible?

A: Both parts use DO-15 axial through-hole packaging. The 2M36Z is specified as DO-204AC (DO-15), and the 1N5365B-TP is specified as DO-15. These designations refer to the same physical package, ensuring mechanical compatibility in through-hole PCB applications.

Q: What is the impact of the 25°C difference in maximum operating temperature?

A: The 2M36Z operates to 175°C junction temperature, while the 1N5365B-TP operates to 150°C. For applications with maximum ambient temperatures below 125°C and typical thermal design margins, both parts are suitable. Applications requiring operation near or above 150°C junction temperature require the 2M36Z.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 2M36Z and 1N5365B-TP are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. Both carry Moisture Sensitivity Level 1 (unlimited), indicating no moisture sensitivity restrictions.
