Schottky Diodes
As an important member of the semiconductor device family, Schottky diodes play a critical role in power management, rectifier circuits, and high-speed switching applications due to their low forward voltage drop and ultra-fast switching speed. Schottky diodes are renowned for their high performance and reliability, and are widely used in automotive electronics, industrial control, and consumer electronics fields.
ESD Protection Diode
ESD protection diodes play a critical role in modern electronic devices, particularly in interface protection and high-speed data line protection.
ON's ultra-low junction capacitance ESD protection diodes feature extremely low junction capacitance (typically below 0.5 pF), enabling reliable ESD protection for high-speed data interfaces (such as USB 3.0, HDMI, DisplayPort, etc.) without compromising signal integrity. ESD protection diodes are specifically designed for automotive electronic systems, capable of withstanding harsh operating environments and higher ESD surges.
Zener Diodes
Zener diodes (also known as voltage regulator diodes) are commonly used as voltage references and overvoltage protection devices in electronic circuits. Zener diodes cover a wide range of applications from low power to high power.
ON Zener diodes include:
Low-voltage Zener diodes: With voltage regulation values ranging from 2.4V to 5.6V, they are commonly used as voltage references and voltage regulators in low-voltage digital circuits.
Medium-voltage Zener diodes: with voltage regulation values ranging from 6.2V to 24V, suitable for general power supply voltage regulation circuits
High-voltage Zener diodes: with voltage regulation values ranging from 27V to 200V, used in high-voltage power supplies and special industrial applications
High-precision Zener diodes: featuring strict voltage tolerances and temperature coefficients, suitable for precision electronic equipment
RF diodes
RF diodes play an indispensable role in high-frequency applications such as wireless communication, radar systems, and satellite communication. ON offers a variety of RF diode products, including Gunn diodes, PIN diodes, Schottky diodes, and varactor diodes.
Gunn diodes are important active components in the microwave frequency band, featuring ultra-low phase noise and 1/f noise characteristics, with a frequency range covering the Ku band. These diodes are commonly used in high-reliability, ultra-low phase noise systems such as transmitters, receivers, beacons, radar systems, radiometers, and precision instruments. Due to the complex production process of Gunn diodes and relatively limited market supply, their recycling value remains at a high level. Mingjiada Electronics, with its professional testing equipment and technical team, can accurately assess the performance and residual value of different models of Gunn diodes.
PIN diodes, as core components of RF switches and attenuators, hold a significant position in ON's product line.
PIN diodes include:
Ultra-low junction capacitance (Cj) PIN diodes: Suitable for high-frequency switching applications with extremely low insertion loss
Wideband bandgap PIN diodes: Covering a broad frequency range, suitable for multi-band applications
High-power switching/attenuating PIN diodes: capable of handling higher RF power, used in applications such as transmitter protection
Radiation detection PIN diodes: featuring a larger sensitive volume, used for radiation detection and measurement
RF Schottky diodes are specially optimised for high-frequency applications compared to standard Schottky diodes. ON RF Schottky diodes are available in two material types: silicon (Si) and gallium arsenide (GaAs), and are offered in various forms, including flip-chip, surface-mount, and standard packages. These diodes feature a unique structural design that provides high breakdown voltage and true Schottky characteristics, and are renowned for their fast switching and low on-voltage, making them widely used in RF circuits such as mixers, detectors, limiters, and pulse shapers.
Varactor diodes are critical tuning components in RF circuits. ON's varactor diodes offer multiple packaging styles, as well as bare die, steep, and ultra-steep Si and GaAs varactor diodes, featuring high tuning ratio and high Q-factor at high frequencies. ON varactor diodes are primarily used in circuits such as voltage-controlled oscillators (VCOs), phase-locked oscillators, and high-Q tunable filters.
