2M30ZH Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M30ZH is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 30 V nominal Zener voltage and 2 W maximum power dissipation. This component is packaged in DO-204AC (DO-15) axial through-hole configuration and is qualified to AEC-Q101 automotive standards. Substitute parts are identified when equivalent electrical parameters and mechanical compatibility exist, enabling component sourcing flexibility while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M30ZH is permissible when the alternative component meets the following criteria:

Critical Electrical Parameters (Must Match):

• Voltage - Zener (Nom): 30 V
• Tolerance: ±5%
• Current - Reverse Leakage @ Vr: 500 nA @ 22.8 V

Compatible Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15 (Axial)

Compliance Requirements:

• RoHS3 Compliant status
• Active product status

The 1N5363B-TP satisfies these substitution criteria. While the 1N5363B-TP provides higher maximum power dissipation (5 W versus 2 W) and lower impedance (8 Ohms versus 20 Ohms), these represent performance enhancements rather than deviations. The substitute maintains identical Zener voltage, tolerance, reverse leakage characteristics, and through-hole axial packaging, ensuring direct functional compatibility in circuits designed for the 2M30ZH.

Engineering Selection Recommendations

2M30ZH Selection Criteria:

• Automotive-grade applications requiring AEC-Q101 qualification
• Circuits with strict 2 W power dissipation limits
• Designs requiring operating temperature range to 175°C
• Applications where higher impedance (20 Ohms) is specified

1N5363B-TP Selection Criteria:

• General-purpose 30 V Zener applications
• Circuits benefiting from higher power handling (5 W)
• Designs where lower impedance (8 Ohms) improves regulation
• Operating temperature requirements up to 150°C
• Applications where automotive qualification is not mandated

Both components are active-status products with ROHS3 compliance and identical Zener voltage and tolerance specifications. The 1N5363B-TP provides enhanced thermal performance through higher power rating and improved dynamic impedance characteristics, making it suitable for higher-dissipation circuit topologies while maintaining electrical equivalence at the 30 V Zener point.

Frequently Asked Questions (FAQ)

Q: Can the 1N5363B-TP directly replace the 2M30ZH in an automotive circuit?

A: The 1N5363B-TP is electrically equivalent at the 30 V Zener voltage and tolerance level. However, the 2M30ZH carries AEC-Q101 automotive qualification, while the 1N5363B-TP does not. Automotive applications requiring AEC-Q101 certification must use the 2M30ZH.

Q: What is the significance of the 2 W versus 5 W power rating difference?

A: The 2M30ZH is rated for maximum 2 W power dissipation, while the 1N5363B-TP handles 5 W. In circuits where the Zener diode dissipates power below 2 W, both components function identically. Circuits requiring dissipation between 2 W and 5 W require the 1N5363B-TP.

Q: Are the DO-204AC and DO-15 packages identical?

A: DO-204AC and DO-15 refer to the same axial through-hole package configuration. Both the 2M30ZH and 1N5363B-TP use this package type, ensuring mechanical compatibility in PCB layouts.

Q: How do the impedance values affect circuit performance?

A: Impedance (Zzt) affects Zener regulation quality. The 1N5363B-TP has lower impedance (8 Ohms versus 20 Ohms), resulting in better voltage regulation under load changes. For applications requiring tighter regulation, the 1N5363B-TP provides superior performance.

Q: What is the operating temperature difference between these parts?

A: The 2M30ZH operates from -55°C to 175°C, while the 1N5363B-TP operates from -55°C to 150°C. Applications requiring operation above 150°C must use the 2M30ZH.

Q: Are both parts RoHS compliant?

A: Yes, both the 2M30ZH and 1N5363B-TP are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and distribution.

Q: What does the reverse leakage specification indicate?

A: Both components specify 500 nA reverse leakage at 22.8 V, indicating identical leakage characteristics. This parameter affects standby current in circuits and is critical for low-power applications.
