Product specication
18-fold ESD transient voltage suppressor
BZA100
FEATURES
SO20 SMD package allows 18
separate voltage regulator diodes
in a common anode configuration
Working voltage: typ. 6.8 V
Forward voltage: max. 1.3 V
Maximum reverse peak power
dissipation: 27.5 W at tp =1ms
Maximum clamping voltage at peak
pulse current: 11 V at 2.5 A
Low leakage current: max. 2 A
ESD rating >8 kV, according
IEC 801-2.
APPLICATIONS
Where transient overvoltage
protection in voltage and ESD
sensitive equipment is required
such as:
– Computers
– Printers
– Business machines
– Communication systems
– Medical equipment.
DESCRIPTION
18-fold monolitic transient voltage
suppressor. Its 18-fold junction
common anode design protects 18
separate lines using only one
package. This device is ideal for
situations where board space is a
premium.
