ZMM39R13 Equivalent & Substitute Parts

Part Overview

The ZMM39R13 is an active Zener diode manufactured by Diotec Semiconductor, designed for voltage regulation and protection applications in surface mount configurations. This component operates at a nominal Zener voltage of 39 V with a maximum power dissipation of 500 mW and is housed in the SOD-80C package. The part is RoHS3 compliant and currently in active production status with 1016 pieces available in new original inventory. Substitute parts are identified when electrical parameters, mechanical compatibility, and operational characteristics align with the original specification, enabling direct replacement in circuit designs without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters:

• Zener voltage (Nominal): 39 V
• Voltage tolerance: ±5%
• Maximum power dissipation: 500 mW
• Maximum impedance: 90 Ohms
• Reverse leakage current: 100 nA @ 30 V

Mechanical Parameters:

• Mounting type: Surface Mount
• Package designation: SOD-80C (DO-213AC, MINI-MELF)

Environmental Parameters:

• Operating temperature range: -50°C to 175°C (TJ)

Substitute parts must match all electrical specifications and maintain mechanical compatibility with the SOD-80C package footprint. Packaging format (Tape & Reel versus other configurations) does not affect electrical or mechanical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The ZMM39 is a direct parametric equivalent to the ZMM39R13, with identical electrical specifications and mechanical compatibility. Both components are manufactured by Diotec Semiconductor and share the same SOD-80C package designation.

Product Status Consideration: The ZMM39R13 maintains active production status with RoHS3 compliance certification. The ZMM39 substitute also maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance and Certification: The ZMM39R13 is RoHS3 compliant. The ZMM39 substitute does not specify RoHS status in the provided data; however, both parts are manufactured by the same supplier and share identical electrical and mechanical specifications, indicating compatibility with equivalent regulatory frameworks.

Inventory Availability: The ZMM39R13 has 1016 pieces in new original inventory. The ZMM39 substitute has 17400 pieces in new original inventory, providing enhanced supply availability for high-volume applications.

Selection between these parts should be based on packaging format requirements (Tape & Reel versus other configurations) and inventory availability for the specific procurement timeline.

Frequently Asked Questions (FAQ)

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

A: Yes. The ZMM39 is a parametric equivalent with identical Zener voltage (39 V), tolerance (±5%), maximum power (500 mW), impedance (90 Ohms), reverse leakage current (100 nA @ 30 V), operating temperature range (-50°C to 175°C), and SOD-80C package designation. Both are manufactured by Diotec Semiconductor.

Q: Are there any package or footprint differences between these parts?

A: No. Both the ZMM39R13 and ZMM39 use the SOD-80C package (DO-213AC, MINI-MELF, SOD-80), ensuring identical PCB footprint compatibility and mechanical mounting characteristics.

Q: What is the difference between the ZMM39R13 and ZMM39 part numbers?

A: The primary difference is packaging format. The ZMM39R13 is supplied in standard packaging, while the ZMM39 is supplied in Tape & Reel (TR) format. Electrical and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: The ZMM39R13 is explicitly RoHS3 compliant. The ZMM39 does not specify RoHS status in the provided documentation; however, both parts are manufactured by Diotec Semiconductor with identical specifications, indicating equivalent compliance frameworks.

Q: Which part should be selected for high-volume production?

A: The ZMM39 is recommended for high-volume applications due to significantly higher inventory availability (17400 pieces versus 1016 pieces) and Tape & Reel packaging format, which is standard for automated assembly processes.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The ZMM39 and ZMM39R13 are electrically and mechanically interchangeable. Circuit performance, voltage regulation characteristics, and thermal behavior remain identical when substituting between these parts.
