AV / AVY Series — Automotive SMD Varistors
Description
Almost all electronic systems in internal-combustion powered vehicles, e.g, anti-lock brakes,
direct ignition, airbag control, wiper motors, etc. are susceptible to damage from destructive
voltage transients.
AV varistors are TVS chips that have suppression characteristics enabling protection from
-55°C to +125°C (+150°C for AVY). These multilyer varistors offer excellent transient energy
absorption in a small package due to improved internal energy distribution. AV series parts
require significantly smaller space and pad area than silicon TVS diodes, offering greater
circuit board layout flexibility for designer.
Features
• AC operating voltage range (Vrms) from 14V to 35V
• DC operating voltage (Vdc) from 16V to 42V
• Power supply voltages (Vdc) 12V, 24V and 42V
• Broad range of current and energy handling capabilities
• 6 model sizes available 1206, 1210, 1812, 2220,
and 3225
• No plastic coating guarantees better flammability rating
• Dimensional and weight savings on PC board
• AgPd end terminations
• Ultra-low inductance, leadless chip guarantees the
fastest response time to transient surges
