Diodes Incorporated is
introducing a range of 84 new
automotive-compliant transient
voltage suppressors (TVS)
packaged in a choice of SMA,
SMB or SMC packages.
Designed to protect sensitive
electronic circuits from
powerline transients generated
by inductive switching, these
devices target a wide range of
automotive applications
including pumps, HVAC,
infotainment, navigation and
ADAS.
Featuring a choice of reverse
stand-off voltage from 14V to
36V these new automotivecompliant TVS are offered as
unidirectional or bidirectional
devices and are able to
dissipate up to 400W (SMA),
600W (SMB) and 3000W
(SMC) per 10/1000µs pulse
transient.
All devices comply with the
automotive load dump standard
ISO7637-2 (pulses 1, 2a, 2b, 3)
and ESD standard ISO10605.
The Diodes Advantage
AEC-Q101 Qualified and PPAP Supported
These devices are qualified to high reliability qualification standards in
accordance with AEC-Q101 and supported by a production part approval
procedure (PPAP).
ISO 10605 Compliance
These parts are suitable to protect sensitive automotive circuits against
electrostatic discharges according to ISO10605.
ISO 7637-2 Compliance
These parts are suitable to protect sensitive automotive circuits against surges
defined in ISO7637-2 (pulses 1,2a, 2b and 3).
High Forward Surge Current Capability and Excellent Clamping
Capability
The high forward surge overload rating and excellent clamping capability
ensures more rugged applications and improves device reliability.
Applications
Advanced Driver Assistance
Systems (ADAS)
Infotainment
Navigation
HVAC (Heating, Ventilation &
Air Conditioning)
Body Control Modules

Circuit Function
Powerline protection of automotive Electronic Control Units (ECU) is important to avoid surge voltages,
generated by the alternator or other inductive loads (motors), passing through to sensitive electronics.
Thus powerline protection is required for almost all automotive electronics.
