A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts .

pin二极管相比于普通二极管增加了一层本征层（i层），使得其用途及其广泛，尤其是在射频领域和光电探测方面。 因此，深入研究PIN二极管的原理和特性是很有意义的。

Infineon PIN diodes are ideal for a wide range of RF applications. Their low insertion loss and fast switching time makes them ideal for use in Rx-Tx antenna switches. They are offered in industry-standard 0201 and 0402 form factors as well as conventional industry packages and various junction diode configurations.

Microsemi PIN diodes offer a unique highly reliable package due to voidless construction, metallurically bonded pin structure, and an extremely rugged SOGO surface passivation. SOGO passivated devices may be driven into reverse voltage breakdown without the reverse voltage characteristic collapsing.

2016年12月28日 · PIN diode basics. A PIN diode behaves as a current-controlled resistor at radio and microwave frequencies. Like the conventional PN diode, it allows current flow in one direction when forward biased, but not in the other when it is reverse biased. This functionality is a simple and critical functional block of many circuits spanning DC to RF.

pin二极管是一种特殊半导体器件，由p-i-n三层结构组成，具有高阻抗和低噪声特性。其i层在施加不同直流电压时，载流子数量变化影响阻抗状态，可用于微波信号的通断控制。pin光电二极管在高速通信和传感系统中发挥关键作用，如光信号响应和安防系统应用。
