New SMD Signal, Rectifier and TVS Diodes Now Available

2026-08-06

We have expanded our portfolio with new signal, rectifier and TVS diodes

Our offer has been expanded with new models of signal, rectifier and TVS diodes designed for a wide range of electronic and industrial applications. The new products include fast and ultra-fast switching diodes, high-voltage rectifier diodes, as well as TVS diodes providing protection against transient overvoltages and the effects of ESD events. The components are characterized by high reliability, compact SMD packages and availability in Tape & Reel packaging, making them suitable for both prototyping and series production.

MDD (Microdiode Semiconductor) is a semiconductor component manufacturer specializing in the design and production of diodes, transistors, MOSFETs, bridge rectifiers and SiC solutions. The company has been developing semiconductor technologies for over a decade and provides solutions for various industrial sectors.

Key features:

  • Wide range of signal, rectifier and TVS diodes,
  • Reverse voltages up to 1000V and forward currents up to 1A (for selected models),
  • Switching time below 4ns (for selected signal diode models),
  • TVS diodes with pulse power ratings of 400W and 600W,
  • Unidirectional and bidirectional versions,
  • TVS diode operating voltage range from 5V to 36V,
  • Selected models designed for operation at temperatures from -55°C to +150°C,
  • Compact SMD packages for surface-mount assembly,
  • Tape & Reel packaging enabling automated assembly,
  • Selected models are replacements for the SM6T and P6SMB series (after parameter verification),

Applications:

  • Protection of electronic circuits against transient overvoltages and selected ESD events,
  • Fast signal switching in digital and analog circuits,
  • Voltage rectification in switching power supplies and power systems,
  • Industrial electronics and automation systems,
  • Telecommunication and networking equipment,
  • Consumer electronics and household appliances,
  • IoT modules and embedded systems,
  • Controllers, communication modules and input/output interfaces,
  • Automotive electronics,
  • Devices requiring reliable surge protection and fast response of semiconductor protection solutions.
