Silicon Diodes – High-Performance Semiconductors for Your Applications
They are indispensable in modern electronics: silicon-based diodes.
These semiconductor components allow current to flow in one direction while blocking it in the opposite direction.
This property makes them essential building blocks in a wide range of applications - from simple rectification to complex switching circuits.
alfatec offers a broad selection of Si diodes. As a partner of Techsem, we provide various package types and performance classes. Our portfolio includes:
- Capsule Cell Diodes: Techsem’s diodes are known for their high current-carrying capacity up to 6800 A and robust construction. They are ideal for power electronics applications such as frequency converters, power supplies, and welding equipment, and can withstand voltages from 400 V to 2000 V.
- Power Modules: These modules contain multiple diodes in a single housing and offer high power density with voltage ratings from 1200 V to 2500 V and up to 570 A. They are commonly used in drive technology and renewable energy systems.

Technical Characteristics of This Diode Type
The Si diode is based on the semiconductor material silicon. Doping with foreign atoms creates regions with different charge carrier concentrations (p-type and n-type). At the junction of these regions - the pn-junction - an electric field forms that blocks current in reverse bias. In forward bias, charge carriers can overcome this barrier, allowing current to flow.
Semiconductors like silicon are the heart of modern electronics. Their ability to control electrical current enables a wide range of electronic devices and applications. In addition to silicon, other semiconductor materials such as germanium and gallium arsenide are used in specialized applications.
Key technical parameters of Si diodes include:
- Forward Voltage (VF): The voltage drop across the diode when operated in forward direction.
- Reverse Voltage (VR): The maximum voltage that can be applied in reverse direction without damaging the diode.
- Forward Current (IF): The maximum current that can flow through the diode in forward direction.
- Reverse Current (IR): The current that flows through the diode in reverse direction.
- Switching Frequency: The frequency at which the diode can switch between conducting and blocking states.
- Switching Losses: Energy losses that occur during the switching process.
The reverse voltage is a critical parameter for the safety and reliability of a semiconductor diode. Exceeding this value can damage or destroy the diode.
