High Voltage Diodes & Assemblies

PPM supplies high voltage diodes and assemblies from Dean Technology (incorporating CKE and HVCA).

Discrete Diodes suitable for applications such as:

High voltage power supplies
X-ray systems
AC rectifiers

Diode Assemblies for use in high voltage and high current applications such as:

Induction heating
Power supplies
Inverters

CKE & HVCA Products

The CKE product line includes high voltage and high power silicon rectifiers, metal oxide varistor modules (MOVs), selenium suppressors, silicon carbide varistors, and assemblies. These products are particularly suited to applications such as power generation, resistance welding and RF power systems.

The HVCA product line includes high voltage diodes, ceramic capacitors, bridge rectifiers and assemblies. Advanced diffusion and manufacturing techniques mean a wide range of diodes and rectifier products.

Customised Products

All products can be customised and are offered with a variety of packaging and connector options, usually with short lead times. Dean Technology has expertise in high voltage assembly and encapsulation so replication of most any competitive or discontinued part is possible.
