Philips Semiconductors
9-fold ESD transient voltage suppressor
Product specification
BZA109
FEATURES
• ESD rating >8 kV, according to
IEC1000-4-2
• SOT163-1 surface mount package
• Common anode configuration
• Non-clamping range 0.5 to 6.8 V
• Maximum non-repetitive peak
reverse power dissipation: 25 W
at tp = 1 ms
• Maximum clamping voltage at peak
pulse current: 10 V at IZSM = 2.5 A.
APPLICATIONS
• For 9-bit wide undershoot/
overshoot clamping and fast ESD
transient suppression in:
– Computers and peripherals
– Audio and video equipment
– Business machines
– Communication systems
– Medical equipment.
DESCRIPTION
9-fold monolithic transient voltage
suppressor in an SO20; SOT163-1
surface mount package. The device is
ideal in situations where board space
is a premium.
