2M30Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M30Z is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 30 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 requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M30Z is permissible when the following electrical and mechanical criteria are met:

Primary Substitution Criteria:

• Zener voltage (Vz) must equal 30 V nominal
• Tolerance must be ±5% or tighter
• Reverse leakage current must not exceed 500 nA @ 22.8 V
• Package type must be DO-15 axial through-hole configuration
• RoHS3 compliance required
• Operating temperature range must encompass application requirements

Secondary Considerations:

• Power rating may exceed 2 W (higher power rating is acceptable for equivalent voltage regulation)
• Impedance (Zzt) may be lower than 20 Ohms (lower impedance provides improved regulation characteristics)
• Forward voltage specifications do not affect Zener diode substitution validity

The 1N5363B-TP meets all primary substitution criteria and provides enhanced performance characteristics through higher power rating and lower impedance.

Engineering Selection Recommendations

2M30Z Selection:

• Primary choice when 2 W power dissipation specification is exact requirement
• Preferred when tape and reel packaging is required for automated assembly
• Suitable for applications with maximum operating temperature requirement of 175°C

1N5363B-TP Selection:

• Acceptable substitute when power dissipation margin is beneficial
• Lower impedance (8 Ohms vs. 20 Ohms) provides superior voltage regulation stability
• Cut tape packaging suitable for manual or semi-automated assembly processes
• Operating temperature range of -55°C to 150°C is sufficient for most industrial applications
• Higher inventory availability (8901 pcs vs. 1067 pcs) supports supply chain continuity

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical Zener voltage and tolerance specifications. Selection between these parts is determined by power budget, impedance requirements, temperature operating range, and packaging format needs.

Frequently Asked Questions (FAQ)

Q: Can the 1N5363B-TP replace the 2M30Z in all applications?

A: The 1N5363B-TP is electrically compatible for Zener voltage regulation applications. The 5 W power rating and 8 Ohm impedance provide equivalent or superior performance to the 2 W, 20 Ohm specification. Verify that the application operating temperature does not exceed 150°C, as the 1N5363B-TP maximum operating temperature is 25°C lower than the 2M30Z.

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

A: Impedance (Zzt) affects voltage regulation quality under load changes. The 1N5363B-TP impedance of 8 Ohms is lower than the 2M30Z impedance of 20 Ohms, resulting in tighter voltage regulation and reduced output voltage variation during transient conditions.

Q: Are the packaging formats interchangeable?

A: Both parts use DO-15 axial through-hole packages and are mechanically compatible for PCB mounting. The 2M30Z is supplied in tape and reel format, while the 1N5363B-TP is supplied in cut tape format. This difference affects handling and assembly processes but does not impact electrical performance or board-level compatibility.

Q: Do both parts meet compliance requirements?

A: Both the 2M30Z and 1N5363B-TP are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0050. Moisture sensitivity level is 1 (unlimited) for both parts.

Q: What is the reverse leakage current specification?

A: Both parts specify 500 nA maximum reverse leakage current measured at 22.8 V. This parameter is identical across both components and does not differentiate substitution suitability.

Q: How does the Zener voltage tolerance affect circuit design?

A: Both parts maintain ±5% Zener voltage tolerance at 30 V nominal. This tolerance range (28.5 V to 31.5 V) must be accommodated in circuit design. No difference exists between the two parts in this specification.
