Product Description
Vishay SMA6F28A-M3/H Uni-Directional TVS Diode is a robust transient voltage suppressor delivering 600 W peak pulse power designed for protecting sensitive electronic devices against transient voltage spikes. It incorporates a 2-pin DO-221 package type with a compact form factor suitable for automated PCB assembly.
Featuring a minimum breakdown voltage of 31.1 V and a reverse stand-off voltage of 28 V, this diode effectively clamps voltage peaks up to 45.5 V, preventing damage during electrical surges such as those caused by inductive load switching and lightning strikes.
The device supports a maximum peak pulse current of 68 A and is optimized for use in single-element, uni-directional configurations. Its operating temperature range from -55°C to 175°C supports durability under harsh industrial and commercial environments.
With a low profile height of approximately 1 mm and precise dimensions (length 4.35 mm, width 2.7 mm), it fits compact designs and meets Moisture Sensitivity Level 1 per J-STD-020 standards, making it ideal for automated surface-mount production with lead-free soldering requirements.
Low leakage current (1 μA) ensures energy efficiency, while its ESD protection capabilities safeguard integrated circuits, MOSFETs, sensor units, and signal lines in consumer electronics, computing, telecommunications, industrial automation, and manufacturing plants.
Applications include voltage transient suppression in sensitive electronics, industrial control systems, and telecommunication infrastructure to enhance reliability and lifespan of critical equipment.
The diode provides excellent clamping voltage performance ensuring voltage spikes are safely limited. Uni-directional polarity is ideal for circuits requiring single-direction voltage suppression. Compact DO-221 packaging supports space-constrained PCB layouts with automated assembly.
The diode is rated for harsh industrial and commercial use with wide temperature tolerance. Low leakage current and high peak pulse power dissipation offer effective protection with minimal power wastage. Meets Moisture Sensitivity Level 1 (MSL 1) for robust manufacturing and handling processes.
Ideal for diverse industrial, laboratory, telecommunications, and consumer electronics environments. Explore more TVS Diode solutions at EnvMart for advanced transient voltage protection needs.
