Germanium diode is an AT93C66B-SSHM-T diode made of germanium (Ge) material. Germanium is a common semiconductor material with a lower bandgap (about 0.67 eV), which was used earlier than silicon (Si) to manufacture semiconductor devices. Below, we will provide a detailed introduction to the basic structure, performance parameters, working principle, application examples, differences from silicon diodes, and development history of germanium diodes
Varactor diode, also known as a capacitive diode, is a special type of diode that has the characteristic of variable capacitance. Its working principle is based on the reverse bias of the PN junction, which changes the capacitance value by altering the reverse voltage. Varactor diodes are widely used in fields such as RF circuits, oscillators, filters, etc. Their functions and characteristics are as follows
Selecting the appropriate diode model is a highly technical process that involves a deep understanding of the working principle of diodes, different types of diodes, and their applications in circuits. Here are several key factors to consider when selecting diodes:
A bidirectional trigger diode (also known as a bidirectional thyristor, bidirectional thyristor, or DIAC) is an electronic component that can conduct electricity in two directions. Unlike unidirectional trigger diodes (DIACs), bidirectional trigger diodes do not have an "anode" and a "cathode", but instead have two electrodes, commonly referred to as A1 and A2 or MT1 and MT2. Its characteristic is that it has similar electrical characteristics in both directions. Bidirectional trigger diodes ar
A relay is an electronic device that primarily controls larger currents or voltages by inputting small currents or voltages into a circuit. This device mainly consists of an electromagnetic coil, a switch, and a spring. When current passes through a coil, it generates a magnetic field that attracts the switch and causes it to close. In this way, larger currents or voltages can flow through the switch. When the current stops flowing, the spring will push the switch back to its original position a
Three phase bridge rectifier circuit is a common power electronic circuit, mainly used in scenarios where AC power is converted to DC power. This circuit uses three-phase power supply, which can provide a more stable and efficient DC power supply than single-phase rectification circuits.
