MM5Z13VT1 Equivalent & Substitute Parts

Part Overview

The MM5Z13VT1 is a Zener diode rated at 13 V nominal voltage with 100 mW maximum power dissipation in a surface mount SOD-523 package. Manufactured by onsemi, this component is classified as obsolete product status. Due to its obsolete designation, sourcing original stock presents supply chain challenges. Equivalent and substitute parts with active product status provide viable alternatives for new designs and production requirements while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM5Z13VT1 is determined by the following critical parameters:

Electrical Parameters (Must Match or Exceed):

• Voltage - Zener (Nom): 13 V
• Tolerance: ±6% or better
• Power - Max: 100 mW or greater
• Impedance (Max): 30 Ohms or lower
• Current - Reverse Leakage @ Vr: 100 nA @ 8 V or lower
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA or lower
• Operating Temperature Range: -65°C ~ 150°C or equivalent

Mechanical Parameters (Must Match or Be Compatible):

• Mounting Type: Surface Mount
• Package / Case: SOD-523 or compatible surface mount packages (SOD-323, SOD-323F, 0603/SOD-523F, EMD2)

Substitute parts are grouped into three categories based on their relationship to the main part:

1. Direct Manufacturer Equivalent: Same manufacturer (onsemi), identical electrical specifications, different package with higher power rating
2. Similar Manufacturer Parts: Different manufacturers, matching nominal voltage and core electrical characteristics, alternative packages with enhanced specifications
3. Parametric Equivalent: Different manufacturer, matching electrical specifications and power rating, same package type

Engineering Selection Recommendations

MM3Z13VT1G (onsemi)

This part is the direct manufacturer equivalent from onsemi with active product status. It maintains identical electrical specifications (13 V, ±6% tolerance, 100 mW minimum power rating) and operates across the same temperature range. The primary difference is the package format (SOD-323 versus SOD-523), which is a standard surface mount variant. This part is ROHS3 compliant and represents the preferred choice for designs requiring onsemi sourcing continuity.

BZX84J-C13,115 (Nexperia USA Inc.)

This part exceeds the electrical requirements of the MM5Z13VT1 with 550 mW power rating and superior impedance characteristics (10 Ohms). It carries AEC-Q101 automotive qualification and ROHS3 compliance. The SOD-323F package is a standard surface mount variant. This selection is appropriate for applications requiring automotive-grade components or enhanced thermal performance.

CZRU52C13 (Comchip Technology)

This part meets the core electrical specifications with 150 mW power rating and ±5% tolerance. It is ROHS3 compliant with active product status. The operating temperature range (-55°C ~ 125°C) is narrower than the original specification. The 0603/SOD-523F package is a standard surface mount format. This selection is suitable for commercial applications where the reduced temperature range is acceptable.

EDZVFHT2R13B (Rohm Semiconductor)

This part provides superior tolerance (±2.23%) and carries AEC-Q101 automotive qualification with ROHS3 compliance. The 150 mW power rating exceeds the original specification. The package format (EMD2) is compatible with SOD-523 footprints. This selection is appropriate for automotive applications or designs requiring tighter voltage tolerance.

BZT52C13T-TP (Micro Commercial Co)

This part is a parametric equivalent with matching electrical specifications (13 V, 100 mW, ±5% tolerance) and identical SOD-523 package. It is ROHS3 compliant with active product status and operates across the full temperature range (-65°C ~ 150°C). This selection provides direct functional replacement with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can MM3Z13VT1G be used as a direct replacement for MM5Z13VT1?

A: Yes. Both parts are manufactured by onsemi with identical electrical specifications (13 V nominal, ±6% tolerance, 100 mW minimum power). The primary difference is the package format (SOD-323 versus SOD-523). Both are surface mount packages with compatible footprints for most applications. Verify PCB layout compatibility before implementation.

Q: What is the difference between SOD-523 and SOD-323 packages?

A: SOD-523 and SOD-323 are both surface mount diode packages with different physical dimensions. SOD-323 is larger than SOD-523. Both packages are standard surface mount formats. PCB layout and component placement must accommodate the specific package dimensions. Consult package datasheets for exact measurements.

Q: Why is BZX84J-C13,115 rated for 550 mW when the original part is 100 mW?

A: The higher power rating indicates greater thermal dissipation capability. This part can safely handle higher power levels without exceeding maximum junction temperature. For applications requiring only 100 mW, this part operates well within its specifications and provides design margin. The higher rating does not affect electrical performance at lower power levels.

Q: Is EDZVFHT2R13B suitable for non-automotive applications?

A: Yes. EDZVFHT2R13B is qualified to AEC-Q101 automotive standards, which means it meets stringent reliability and quality requirements. These qualifications exceed typical commercial-grade requirements. This part is suitable for any application, including non-automotive designs, where enhanced reliability is beneficial.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials. The original MM5Z13VT1 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, making them suitable for applications and regions with RoHS requirements.

Q: Can BZT52C13T-TP replace MM5Z13VT1 in existing designs?

A: Yes. BZT52C13T-TP is a parametric equivalent with matching electrical specifications (13 V, 100 mW, ±5% tolerance) and identical SOD-523 package. It operates across the same temperature range (-65°C ~ 150°C). This part provides direct functional replacement with improved product status (active) and ROHS3 compliance.

Q: Why does CZRU52C13 have a narrower operating temperature range?

A: CZRU52C13 operates from -55°C ~ 125°C, compared to the original -65°C ~ 150°C range. This narrower range reflects the component's design specifications. For applications operating within the -55°C ~ 125°C window, this part is fully compatible. Applications requiring the full -65°C ~ 150°C range should select alternative parts.

Q: What is impedance (Zzt) and why does it matter for substitution?

A: Impedance (Zzt) is the dynamic impedance of the Zener diode at specified operating conditions. Lower impedance indicates better voltage regulation characteristics. The original part specifies 30 Ohms maximum. Substitute parts with equal or lower impedance (such as BZX84J-C13,115 at 10 Ohms) provide equivalent or superior performance. Higher impedance values may affect voltage regulation.
