SURGE ABSORBERS
KIT prfessors & GIGA president K.Tachibana reported microgap absorber on IEEE, please look
GIGA CORP can make good quality surge absorbers .We can make only glass sealded discharge type but this products can work same speed with semiconducter type.solid PNPNP type can work after free electron born at PN junction.usualy discharge type absorbers can work after thermal electron bornand this thermal electron can born after kathode temperature increase >2000℃so this type need some delay time befor work .usualy more than 1micro sec. Our absorber can work after field emission electron born.from micro-gap. Field emission electron can born very quickly same as solid free electron.and our absorber electrode temperature don't increase , so very stable and strong.

you can get same quality as PNPNP type with low cost.

This photo is typically our surge-absorber out look. length is less than 4mm.out side is less than 2.5mm


all made by PUNSUMI ( India biggest absorber company)
this photo is box type high voltage absorbers. from 1000V to 5000V DC.
High surge current 10*560us 100A 4KV, Huge insulating resister> 10GΩ,low capacitor<2pF,
Low cost , now start using big quantity at India CTV market and China Air-conditioner & ADSL
and Japan Gas control systems.
please order to giga sales manager

This circuit can protect from surge which come from Anntena or AC P/S
