What is the HVC alternative for Diotec 2CL/BY/DD/HV series high voltage diodes?

HVC Capacitor provides comprehensive replacement solutions covering Diotec Semiconductor's complete high-voltage diode portfolio — including the ubiquitous 2CL multiplier stacks, BY high-voltage rectifiers, DD fast recovery diodes, and HV ultra-high-voltage series.

|---------------|------|---------|---------|----------------|-------------|

2CL71 / 2CL73 / 2CL75 / 2CL77	Voltage Multiplier Stack	10kV – 35kV	10mA – 100mA	HVD-Multiplier Stack	✅ Higher PD immunity
BY Series (BY299/BY399 etc.)	HV Rectifier	1kV – 8kV	0.5A – 3A	HVD-BY Equivalent	✅ Faster trr
DD Series (DDxxN)	Fast Recovery	2kV – 6kV	0.2A – 1A	HVD-Fast Recovery	✅ 30% lower Qrr
HV Series (HV08-HV24)	Ultra-HV Rectifier	8kV – 24kV	50mA – 200mA	HVD-UltraHV	✅ Extended to 50kV+

Diotec's 2CL series is the industry-standard building block for Cockcroft-Walton voltage multiplier cascades used in:

* Medical X-ray and CT imaging high-voltage generators

* NDT (Non-Destructive Testing) X-ray inspection equipment

* Electrostatic precipitator power supplies

* Scientific instrumentation (mass spectrometers, electron microscopes)

HVD-Multiplier Stack advantages over 2CL:

* Partial Discharge Inception Voltage (PDIV): HVD achieves >80% of rated voltage before PD onset vs Diotec's typical 60-70%

* Thermal Stability: Junction temperature coefficient reduced by 25%, enabling higher ambient operation without derating

* Surge Withstand: 2x higher IFSM (Forward Surge Non-Repetitive Maximum) rating

* Long-Term Reliability: MTBF projection >500,000 hours under nominal conditions (vs Diotec's ~300,000 hours)
