Product Features
High Voltage Miniaturization
Achieves a 20KV blocking voltage in a standard HV axial package , significantly reducing PCB space compared to stringing multiple lower-voltage diodes together.
Ultra-Fast Recovery (100nS)
Optimized for high-frequency operation (typically up to 100kHz), drastically reducing reverse recovery losses (switching losses) compared to standard high-voltage diodes
Low Leakage & Stability
Extremely low reverse leakage current at high temperatures ensures stable performance in harsh environments and reduces thermal runaway risks.

Applications
This diode is specifically for systems requiring very high DC voltage from a small current source.
Medical Equipment
Electrotherapy: TENS units, muscle stimulators, and electrosurgical pencils require high voltage blocking to prevent patient leakage currents.
Portable Defibrillators: Used in high-voltage charging circuits for the energy storage capacitors.
Test & Measurement
HV Probes: Internal rectification for high-voltage differential probes and oscilloscope probes.
Insulation Testers (Megohmmeters): Generates the 5kV-10kV test voltages; this diode is used in the multiplier stage to step up to higher ranges.
Industrial & Scientific
Mass Spectrometry: Electron multiplier power supplies require ultra-stable 30kV rails.
Electrostatic Systems: Electrostatic precipitators (dust collection) and electrostatic painting/flocking guns.
Laser Power Supplies: Pre-ionization circuits for CO2 lasers or driving flash lamps in small YAG lasers.
HV Power Supplies
Cockcroft-Walton Multipliers: Ideal for the top stages of multipliers where voltage stress is highest but current demand is low.
