CeraDiodes represent a series of ceramic components suitable for protection from voltage surges in audio and video systems, telecommunications, computers, USB, MP3, HDD, notebooks, printers. Particularly, low values of capacitance are normal for such components, that allows to provide maximal protection from electrical discharge and minimal signal dissipation in data link. CeraDiodes are characterised by nonlinear ratio voltage/current, that allows to suppress effectively the voltage surges and to support the stability of electrical features in the working temperature range from -40°С up to +85°С. Thanks to success of Epcos in the field of miniaturization and functionality growth the increasing of demands for compact and complicated electronic equipment is being noted.
The advantages of cera diodes:
- Extra low values of capacity at high speed of data transmission
- Low cost
- Compact
- High data throughput for audio signals (0 Decibell up to 1 MHz)
- Short response time < 0.5 ns
- The ability to withstand high values of peak surge current
Cera diodes features:
- DC voltage: 5.6...30 V
- Capacitance: 0.6...470 pF
- Working temperatures:-40...+85°С
- RoHS
- The protection from static electrical spark corresponds the requirements ESD IEC 61000-4-2, 4 level
- The ability to withstand high values of peak current
During operating the internal resistance of ceradiode is rather high, and it confines the current's flowing through it. However, the increasing of resistance is possible up to predetermined limit. When ahcieving of the defined voltage value (Vleak, V) leackage current flowing can be noticed (I leak, А). These characteristics should be taken in consideration when choosing ceradiodes.
