DiodesZetex MMBZ5242B-7-F is a 12 V nominal Zener diode featuring a single diode configuration housed in a surface mount SOT-23 package. It is engineered for voltage regulation and protection in sensitive electronic circuits where stable voltage reference is required. With a maximum power dissipation of 350 mW, this general purpose Zener diode effectively limits voltage spikes and maintains constant voltage levels in semiconductor applications.
The device features a maximum Zener impedance of 30 Ω and a low reverse leakage current of 1 μA, making it suitable for precision voltage reference and protection in a variety of environments. Its operating temperature range from -65°C to 150°C allows use in both industrial and automotive electronics, further emphasized by compliance with the international RoHS directive and automotive AEC-Q101 qualification.
The compact dimensions of 3 mm length and 1.1 mm height facilitate its use in high-density PCB assemblies, supporting surface mount technology manufacturing processes. The 3-pin configuration ensures ease of integration in modern electronic designs requiring voltage stabilization and transient suppression.
Nominal Zener voltage of 12 V with ±5% tolerance for accurate voltage regulation. Designed for surface mounting in a compact SOT-23 package. Rated for maximum power dissipation of 350 mW to handle typical voltage spikes.
Capable of operation in harsh temperature ranges (-65°C to 150°C). Low maximum leakage current reduces power loss and increases efficiency. Meets RoHS environmental compliance and automotive standard AEC-Q101 for quality assurance.
Maximum Zener impedance of 30 Ω ensures voltage stability under load. Ideal for use in automotive, industrial, and general electronic voltage reference applications.
This Zener diode is essential for industrial, automotive, and electronic circuit design applications requiring reliable voltage regulation and protection in compact form factors. EnvMart offers this DiodesZetex product to support demanding environments and precision electronics manufacturing.
