Product details

Overview

MM3Z13VC from onsemi is a 13 V ±5% Zener diode in SOD−323FL package, rated for 200 mW power dissipation, with 28 Ω zener impedance at 5 mA test current and 0.09 µA reverse leakage at 8 V, used for precision voltage regulation and reference in low-power analog circuits.

For engineers reviewing the MM3Z13VC datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance, thermal resistance (595 °C/W), junction temperature limit (150 °C), and SOD−323FL footprint compatibility in space-constrained PCB designs.

Technical Context

This device operates as a two-terminal voltage reference, conducting in reverse breakdown at nominal 13 V with ±5% initial tolerance. It maintains regulation across 1 mA to 10 mA operating current range and exhibits low dynamic impedance (28 Ω) under standard 5 mA test conditions.

The SOD−323FL package enables surface-mount integration with minimal board area. Its matte tin finish ensures solderability, and the device complies with RoHS and Pb-free requirements without derating for lead-free reflow profiles.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-B13	Same 13 V ±5%, but SOD-323 package with 400 mW rating and higher 30 Ω Z_ZT	Higher power handling supports 10 mA continuous operation; less suitable for ultra-low-leakage designs	Select when higher surge current capability is required and board layout allows same footprint
MMSZ4686	13 V ±5%, SOD-123 package, 500 mW rating, 30 Ω Z_ZT, 0.1 µA I_R at 8 V	Larger footprint increases PCB area by ~2.5×; better thermal performance but incompatible with SOD−323FL land pattern	Choose when thermal margin is critical and layout revision accommodates larger package

Compared with BZX384-B13 and MMSZ4686, the MM3Z13VC offers the smallest footprint and lowest leakage among 13 V ±5% Zeners, making it optimal for miniaturized, battery-powered systems where board space and quiescent current are constrained.

FAQ

What is the nominal Zener voltage and tolerance of MM3Z13VC?

The MM3Z13VC has a nominal Zener voltage of 13.0 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 12.35 V and 13.65 V when tested at I_ZT = 5 mA. This tolerance is confirmed in the onsemi datasheet Rev. 3 (August 2023) under Electrical Characteristics. The MM3Z13VC achieves this specification using process-controlled silicon doping and laser trimming during final test.

What package type does MM3Z13VC use and what are its key mechanical features?

MM3Z13VC uses the SOD−323FL package (case outline 477AB), a 2-pin ultra-thin surface-mount device with matte tin finish, Pb-free construction, and RoHS compliance. Its dimensions are optimized for high-density layouts, and the cathode is marked with a band on pin 2. The MM3Z13VC's thermal resistance is 595 °C/W when mounted on minimum PCB land pad, per onsemi's thermal characterization.

What is the maximum power dissipation and how does it affect thermal design?

The MM3Z13VC has a maximum power dissipation of 200 mW at T_A = 25 °C. Due to its 595 °C/W junction-to-ambient thermal resistance, even 100 mW dissipation raises junction temperature by ~59.5 °C above ambient-requiring careful derating above 25 °C. The MM3Z13VC must be operated below 200 mW in still-air conditions unless additional copper pour or airflow is provided.

How does the reverse leakage current of MM3Z13VC compare to similar Zener diodes?

The MM3Z13VC specifies 0.09 µA maximum reverse leakage (I_R) at V_R = 8 V, which is lower than many competing 13 V Zeners such as the BZX384-B13 (0.1 µA) and MMSZ4686 (0.1 µA). This low leakage minimizes error in high-impedance reference divider networks. The MM3Z13VC achieves this via optimized epitaxial layer design and controlled diffusion processes.

Can MM3Z13VC be used in place of older through-hole Zener diodes like 1N4742A?

No-MM3Z13VC is not a direct replacement for 1N4742A due to fundamental differences: the 1N4742A is a 13 V, 1 W through-hole device in DO-41 package, while MM3Z13VC is a 13 V, 200 mW SOD−323FL surface-mount part. Their power ratings, thermal paths, and footprints are incompatible. The MM3Z13VC serves modern miniaturized designs; legacy through-hole applications require package- and power-matched alternatives.
