ZMM39R13 Equivalent & Substitute Parts

Part Overview

The ZMM39R13 is a Zener diode manufactured by Diotec Semiconductor, designed for voltage regulation and protection applications requiring a 39 V nominal Zener voltage with 500 mW power dissipation capability. This component is classified as an active product and is available in surface mount packaging (SOD-80C). The ZMM39R13 is supplied in individual packaging format.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Alternative part numbers may be necessary due to inventory availability, packaging format requirements, or supply chain considerations while maintaining identical functional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZMM39R13 is determined by equivalence across the following critical parameters:

• Zener Voltage (Nominal): 39 V
• Voltage Tolerance: ±5%
• Maximum Power Dissipation: 500 mW
• Dynamic Impedance: 90 Ohms (maximum)
• Reverse Leakage Current: 100 nA @ 30 V
• Operating Temperature Range: -50°C to 175°C
• Package Type: SOD-80C (DO-213AC, MINI-MELF)
• Mounting Technology: Surface Mount

The ZMM39 is classified as a parametric equivalent to the ZMM39R13. Both components are manufactured by Diotec Semiconductor and share identical electrical specifications and mechanical compatibility. The primary distinction between these parts is the packaging format: the ZMM39R13 is supplied in individual packaging, while the ZMM39 is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both the ZMM39R13 and ZMM39 are active products manufactured by Diotec Semiconductor with identical electrical and mechanical specifications. Selection between these components is based on packaging and supply requirements:

ZMM39R13 is appropriate for applications requiring individual component packaging or lower-volume procurement where tape and reel format is not necessary.

ZMM39 is appropriate for high-volume manufacturing environments where Tape & Reel (TR) packaging format is standard for automated assembly processes. This part number offers significantly higher inventory availability (17,400 pieces in stock versus 975 pieces for ZMM39R13).

Both components are classified as Active products and maintain identical compliance status. The selection between these parts does not affect circuit performance, thermal characteristics, or electrical behavior. The choice is determined solely by procurement format and manufacturing process requirements.

Frequently Asked Questions (FAQ)

Q: Can ZMM39 be used as a direct replacement for ZMM39R13?

A: Yes. The ZMM39 is a parametric equivalent with identical electrical specifications (39 V nominal Zener voltage, 500 mW power rating, ±5% tolerance, 90 Ohms maximum impedance) and mechanical compatibility (SOD-80C package, surface mount). The only difference is packaging format (Tape & Reel versus individual packaging).

Q: What is the difference between ZMM39R13 and ZMM39?

A: The electrical and mechanical specifications are identical. The ZMM39R13 is supplied in individual packaging, while the ZMM39 is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but not component performance.

Q: Are there any thermal or operating condition differences between these parts?

A: No. Both components share identical operating temperature ranges (-50°C to 175°C junction temperature), maximum power dissipation (500 mW), and reverse leakage characteristics (100 nA @ 30 V).

Q: Which part should be selected for automated assembly?

A: The ZMM39 in Tape & Reel format is designed for automated pick-and-place assembly processes. The ZMM39R13 in individual packaging is suitable for manual assembly or lower-volume applications.

Q: Do both parts meet the same compliance standards?

A: Both components share identical compliance status. RoHS Status is Not Applicable for both parts. ECCN classification is EAR99 for both components.

Q: Is there a performance difference in circuit applications?

A: No. Both parts deliver identical performance in voltage regulation and protection circuits. Circuit behavior, voltage stability, and transient response are equivalent across all operating conditions within the specified temperature range.
