2M15Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M15Z is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 15 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 ROHS3 compliant. Substitute parts are identified based on matching electrical specifications and mechanical compatibility within the Zener diode category. Alternative components may be required due to inventory availability, packaging format preferences, or application-specific power rating requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2M15Z are selected based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Zener voltage rating: 15 V nominal (±5% tolerance band)
• Package type: DO-15 axial through-hole configuration
• Mounting method: Through-hole compatible
• Regulatory compliance: ROHS3 compliant status
• Thermal operating range: Minimum -55°C to 150°C overlap

Acceptable Parameter Variations:

• Power rating: Equal to or greater than 2 W maximum
• Impedance: Lower impedance values are acceptable
• Reverse leakage current: Higher values within specification are acceptable

The substitute parts 1N5352B-TP and 1N5353B-TP meet these criteria with enhanced power ratings (5 W) and improved impedance characteristics. The 1N5353B-TP operates at 16 V nominal Zener voltage, which falls within the tolerance band of applications designed for 15 V ±5% operation.

Parameter Comparison

Engineering Selection Recommendations

1N5352B-TP Selection Criteria: The 1N5352B-TP is a direct electrical equivalent to the 2M15Z, maintaining the 15 V nominal Zener voltage specification. This substitute provides enhanced power dissipation capability (5 W versus 2 W) and superior impedance characteristics (2.5 Ohms versus 7 Ohms). Both components are ROHS3 compliant and REACH unaffected. The 1N5352B-TP operates within the -55°C to 150°C temperature range, which overlaps the 2M15Z operating range. This part is suitable for applications requiring higher power handling or improved voltage regulation stability.

1N5353B-TP Selection Criteria: The 1N5353B-TP operates at 16 V nominal Zener voltage, which falls within the ±5% tolerance band of the 2M15Z (15 V ±5% = 14.25 V to 15.75 V). However, the 1N5353B-TP nominal rating of 16 V exceeds this band. This substitute is applicable only in applications where the 16 V Zener voltage is functionally acceptable. The 1N5353B-TP provides the same enhanced power rating (5 W) and impedance improvement (2.5 Ohms) as the 1N5352B-TP. Both substitute parts are ROHS3 compliant and REACH unaffected.

Compliance and Regulatory Status: All listed components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications. Moisture sensitivity level remains at MSL 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

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

A: The 1N5352B-TP maintains identical Zener voltage (15 V) and tolerance (±5%) specifications. The enhanced power rating (5 W versus 2 W) and lower impedance (2.5 Ohms versus 7 Ohms) make it suitable for direct substitution in applications designed for the 2M15Z. The reduced operating temperature upper limit (150°C versus 175°C) must be verified for high-temperature applications.

Q: Is the 1N5353B-TP compatible with circuits designed for 15 V Zener operation?

A: The 1N5353B-TP operates at 16 V nominal Zener voltage. While this exceeds the 2M15Z specification of 15 V, the 16 V rating falls outside the ±5% tolerance band of the original part (14.25 V to 15.75 V). Substitution is limited to applications where 16 V Zener voltage is functionally acceptable or where circuit design tolerates this voltage shift.

Q: What are the packaging differences between the 2M15Z and substitute parts?

A: All three components use DO-15 axial through-hole packaging. The 2M15Z is supplied in Tape & Reel (TR) format, while the 1N5352B-TP and 1N5353B-TP are supplied in Cut Tape (CT) format. Both packaging formats are compatible with standard through-hole assembly processes and equipment.

Q: Are there temperature range limitations when substituting the 1N5352B-TP or 1N5353B-TP?

A: The substitute parts operate within -55°C to 150°C, while the 2M15Z operates within -55°C to 175°C. Applications requiring sustained operation above 150°C junction temperature must retain the 2M15Z. For applications within the -55°C to 150°C range, the substitute parts are fully compatible.

Q: Do the substitute parts maintain the same regulatory compliance as the 2M15Z?

A: Yes. All three components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0050. Moisture sensitivity level remains MSL 1 (Unlimited) for all parts, indicating equivalent handling and storage requirements.

Q: What is the significance of the lower impedance in the substitute parts?

A: The 1N5352B-TP and 1N5353B-TP feature impedance of 2.5 Ohms compared to the 2M15Z impedance of 7 Ohms. Lower impedance provides improved voltage regulation stability and reduced output impedance variation across the operating current range. This characteristic is beneficial in precision voltage reference applications.
