Product overview
Description
Transil diode arrays provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied IC’s.
The ITA series combines high surge capability against energetic pulses with high voltage performance against ESD.
-
All features
- ESD protection up to 15 kV
- High surge capability Transil array: IPP = 40 A (8/20 µs)
- Up to 5 bidirectional Transil functions
- Peak pulse power: 300 W (8/20 µs)
- Low leakage current
- Low clamping factor (VCL / VBR) at high current level
