Problems solved by technology
[0003] Fast recovery diodes are important components in switching circuits or modulation circuits. However, after the existing fast recovery diodes are damaged, the circuit board needs to be removed, and then the damaged fast recovery diodes can only be taken out by heating the solder joints with a soldering iron. , and then replace with a new fast recovery diode, not only the operation is troublesome, but also other electronic components are easy to be damaged during the process of taking out the circuit board

The invention discloses a patch fast-recovery diode. The patch fast-recovery diode comprises a mounting base, a patch type fast-recovery diode body, a connecting lug, a fixed screw, a first pin, a conductive plate, a pressing head, a pressing block, an elastic metal sheet, a small-sized screwing nut and a second pin; a groove is formed in the top of the mounting base; the patch fast-recovery diode body is arranged in the groove of the mounting base; the connecting lug is arranged at the bottom of the patch fast-recovery diode body; and a mounting hole is formed in the connecting lug. Compared with the prior art, the patch fast-recovery diode has the beneficial effects of scientific and reasonable design; the installation between the patch fast-recovery diode and a circuit board is very convenient; when the diode body needs to be replaced, the patch fast-recovery diode body can be taken out by only rotating the small-sized screwing nut and the fixed screw; and then a new patch fast-recovery diode is inserted into the mounting base, without detaching the circuit board, so that unnecessary trouble can be avoided.
Description
technical field [0001] The invention relates to a diode, in particular to a patch fast recovery diode. Background technique [0002] Fast recovery diode (FRD for short) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in electronic circuits such as switching power supplies, PWM pulse width modulators, and frequency converters. Freewheeling diodes or damping diodes are used. The internal structure of the fast recovery diode is different from the ordinary PN junction diode. It belongs to the PIN junction diode, that is, the base region I is added between the P-type silicon material and the N-type silicon material to form a PIN silicon chip. [0003] Fast recovery diodes are important components in switching circuits or modulation circuits. However, after the existing fast recovery diodes are damaged, the circuit board needs to be removed, and then the damaged fast recovery diodes can only be taken out by heating t...
