Zenamic Z21D
Zenamic is Semitec’s registered trademark for
metal oxide varistors which are transient
voltage surge absorbers. Zenamic features large
surge current and transient overvoltage handling
capabilities. It is produced by sintering a ZnO
based metal oxide mix at temperatures ranging
from 1200 to 1400℃.
Applications
- Semiconductor device protection: Diodes,
transistors, thyristors, IC etc.
- Home electronics protection: TVs, air
conditioners, refrigerators, microwave
ovens, etc.
- Office automation equipment protection:
PPC copiers, fax machines, PCs, etc.
- Industrial equipment protection: Robots,
water heaters, machining equipment, etc.
- Inrush surge protection: Electromagnetic
clutches/brakes, relay control devices,
circuit breakers etc.
- Others: Automotive electronics circuits,
vending machines, communication/broadcasting
equipment, etc.
