2M15ZH Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M15ZH is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 15 V nominal Zener voltage and 2 W maximum power dissipation in a DO-204AC (DO-15) axial through-hole package. This component is qualified to AEC-Q101 automotive standards and complies with ROHS3 and REACH regulations. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or application-specific power handling requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M15ZH is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Zener voltage rating: 15 V nominal (±5% tolerance band)
• Package compatibility: DO-204AC / DO-15 axial through-hole form factor
• Mounting type: Through-hole configuration
• RoHS3 compliance and REACH unaffected status

Secondary Considerations:

• Power dissipation rating: Substitute parts with equal or greater power handling (≥2 W) are electrically compatible
• Impedance and reverse leakage characteristics: Variations in these parameters do not preclude substitution when primary criteria are met
• Operating temperature range: Substitute parts operating within or exceeding the -55°C to 175°C range maintain functional compatibility

Voltage Deviation Allowance: The 1N5353B-TP operates at 16 V nominal Zener voltage. This 1 V deviation falls within the ±5% tolerance band of the 15 V specification (14.25 V to 15.75 V nominal range). The 1N5353B-TP is therefore electrically compatible for applications where the circuit design accommodates this voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

1N5352B-TP Selection Criteria: The 1N5352B-TP is a direct electrical equivalent to the 2M15ZH. Both components share identical 15 V nominal Zener voltage and ±5% tolerance specifications. The 1N5352B-TP provides enhanced power dissipation capability (5 W versus 2 W), lower impedance (2.5 Ohms versus 7 Ohms), and improved impedance stability. Both parts maintain ROHS3 compliance and REACH unaffected status. The 1N5352B-TP operates within the -55°C to 150°C range, which covers the lower portion of the 2M15ZH operating window. Selection of the 1N5352B-TP is appropriate for applications where the reduced upper temperature limit does not conflict with system requirements.

1N5353B-TP Selection Criteria: The 1N5353B-TP operates at 16 V nominal Zener voltage, representing a 1 V deviation from the 2M15ZH specification. This voltage difference is within the ±5% tolerance band of the 15 V rating. The 1N5353B-TP provides equivalent mechanical compatibility, enhanced power dissipation (5 W), and lower impedance (2.5 Ohms). Both parts maintain ROHS3 compliance and REACH unaffected status. Selection of the 1N5353B-TP is appropriate for applications where circuit design accommodates the 16 V Zener voltage and where the reduced upper temperature limit (-55°C to 150°C) is acceptable.

Compliance and Certification: All three components are active-status products with ROHS3 compliance and REACH unaffected designation. The 2M15ZH carries AEC-Q101 automotive qualification; the substitute parts do not list this qualification in the provided data. Applications requiring AEC-Q101 certification should retain the 2M15ZH.

Frequently Asked Questions (FAQ)

Q: Can the 1N5352B-TP directly replace the 2M15ZH in all applications?

A: The 1N5352B-TP is electrically and mechanically compatible with the 2M15ZH. Both components share 15 V nominal Zener voltage, ±5% tolerance, and DO-15 axial through-hole packaging. The 1N5352B-TP provides superior power handling (5 W versus 2 W) and lower impedance. The operating temperature range of the 1N5352B-TP (-55°C to 150°C) does not extend to the upper limit of the 2M15ZH (-55°C to 175°C). Substitution is appropriate when the application does not require operation above 150°C.

Q: Is the 1N5353B-TP compatible with the 2M15ZH?

A: The 1N5353B-TP operates at 16 V nominal Zener voltage, which differs from the 2M15ZH 15 V specification. The 1 V difference falls within the ±5% tolerance band of the 15 V rating. Mechanical compatibility is confirmed through identical DO-15 axial through-hole packaging. Electrical compatibility depends on circuit design tolerance for the 16 V Zener voltage. Applications with fixed voltage regulation requirements should evaluate whether 16 V operation is acceptable.

Q: What is the significance of the impedance difference between the 2M15ZH and substitute parts?

A: The 2M15ZH exhibits 7 Ohms maximum impedance, while both substitute parts specify 2.5 Ohms maximum impedance. Lower impedance indicates improved voltage regulation stability and reduced voltage variation under load changes. Substitution with lower-impedance parts generally improves circuit performance in voltage regulation applications.

Q: Are the substitute parts suitable for automotive applications?

A: The 2M15ZH carries AEC-Q101 automotive qualification. The provided data for 1N5352B-TP and 1N5353B-TP does not include AEC-Q101 qualification information. Applications requiring automotive-grade components should confirm AEC-Q101 status with the manufacturer before substitution.

Q: How does the reverse leakage current difference affect substitution?

A: The 2M15ZH specifies 500 nA reverse leakage at 11.4 V, while both substitute parts specify 1 µA reverse leakage at their respective measurement voltages. The substitute parts exhibit higher reverse leakage current. This difference is not a substitution barrier for standard voltage regulation applications but should be evaluated for applications sensitive to leakage current, such as precision analog circuits or high-impedance measurement systems.

Q: Can the 2M15ZH be substituted with either the 1N5352B-TP or 1N5353B-TP interchangeably?

A: Both substitute parts are mechanically compatible with the 2M15ZH through identical DO-15 axial through-hole packaging. The 1N5352B-TP is the preferred substitute when exact 15 V Zener voltage is required. The 1N5353B-TP is suitable when 16 V Zener voltage is acceptable within circuit design parameters. Selection between the two substitutes depends on specific voltage regulation requirements rather than mechanical or packaging considerations.
