Most of HVC Capacitor’s customer use high voltage ceramic capacitor and high voltage diode to build Voltage multiplier, (CASCADE COCKCROFT-WALTON VOLTAGE MULTIPLIER) which is a basic circuit for X-ray, CT and NDT machine.
In 2018, HVC Capacitor partner with a local famous HV diode producer to win quite a lot of HV projects. Customers also approval the HVC brand diode. In this market, most clients using HVCA brand and EDI brands from the U.S.A, more famous names like Japanese Origin and Sanken. All of the above as world-class renown brands like Vishay, TDK, Murata. Since this is a specialized market and not a massive product market like home electronics and consumer electronics.
HVC hv diode widely used in aerospace, military weapons, mote vehicles, medical X-ray machine, electrostatic dedusting, a scientific research institute.
HVC HV diode peak working revere voltage(VRWM) from 1kv to 30kv, high voltage silicon stack voltage up to 500kv,Average Forward Current( IF(AV)) from 10MA to 20A, Reverse Recovery Time(trr) from 35ns to 2000ns,working frequency 50HZ to 200kHZ.
HVC high voltage diode with the following advantage feature:
1) Low leakage current, high surge, and high current shock resistance
2) High reverse voltage, low forward current and avalanche breakdown protection.
3) Fast response, high efficiency and ultra-fast recovery time.
4) High heat resistance, PN junction temperature up to 175℃
Above mention HVCA brand and EDI both have production bases in Northeastern and Southeastern China.HVC brand high voltage diode with the same quality standard to Chinese producer and already gaining more and more replacement projects in Europe and the American market.
Following is frequency search hv diode part number and HVC provides all alternative and replacement items to them.
1) UX-F0B,UX-C2B,UX-F15B,UX-F30B,UX-F2CL15,this UX-FOB is very popular use in high voltage X-ray machine.UX-FOB original from Japanese Sanken widely uses in high-frequency high voltage circuits. Datasheet show VRRM 8kv, “UX” means ultra-fast recovery time to 40ns, This means high respond and high efficiency for X-ray generator. this model withstands high frequency up to 300khz, surge current 20 Ampere.
From our experience, the UX-FOB diode can be found from famous medical X-ray client Konica Minolta (Mexico), VMI (Brazil) and CPI (Canada)’s (DR) Digital Radiography and much other copy PCB board from the famous name. So the usage of UX-FOB is hugh. This model original produce by Japanese brand Sanken (SK), and later SK stop production, and American diode company HVCA (Dean Technology) start to produce it and market it in the same part number “UX-F0B”.
It is the most popular model design-in to world-famous (high end) X-ray power source manufacturer’s PCB board, due to very fast recovery time and high frequency (300khz) feature. (This is very similar to most popular Murata high voltage ceramic capacitor (15kv 102 ZM material, DHR4E4C102K2FB) also used in the high-end X-ray power source.)
DHR4E4C102K2FB market demand can be one million pcs globally. since this UX-FOB model is super hot, some less famous Japanese component manufacturers even produce replacement models call “MD8CP5”.
HVC also offer alternative and replacement model to UX-FOB, HVC model call HVD-SL513G, which provide same 40ns respond and 13kv reverse voltage, higher voltage withstands can making component more reliable and customer can series connection less diode to achieve given value, and finally cost down to general PCB board.
UX-C2B is Sanken’s HV diode,8kv voltage, and 500ma current, widely use a microwave oven, the typical model is Panasonic’s Microwave Oven. We found HVCA also produce same name model before, but now already disappear from their catalog. HVC offers an alternative for HV diode UX-C2B with competitive cost.
2) 2CL2FL, 2CL2FM, 2CL2FP, HV diode in 15kv to 30kv current from 100ma to 140ma.
This is original HVCA and EDI part number, typical application like X-ray power supply, laser, voltage multiplier circuit, microwave transmission power supply, oil fume purification equipment, net dust removal equipment. HVC diode offers an alternative model.
3) VT1500, RVT1000, RVT1200, RVT1500, HVRT300, HVRT120, HVRT150, HVRT200, this original HVCA item, the major application is a medical device, laser power supply, and dust removal. CRT screen. HVC offers an alternative item to the above.
4) 2CL77, the voltage in 20kv and 5ma current, and similar model 2CL70, 2CL71, 2CL72, 2CL75, 2CL79, they are high voltage but low current diode, very popular and useful in the market.EDI part number, sure HVC offers replacement and alternative to the above item.
5) HVC also offer an alternative replacement for following hot HV diode model which use in a more general application, like:
