Intersil's 400-Volt Ignition IGBT Features Increased Clamp Voltage

Intersil's 400-Volt Automotive Ignition IGBT Features Increased Clamp Voltage; IGBT Meets the Requirements of Coil on Plug Applications; Qualified According To the Latest Automotive Standards

    PALM BAY, Fla., Oct. 15-- Intersil Corporation introduced the newest product in its portfolio of advanced automotive ignition
IGBTs.  Intersil's latest N-Channel IGBT is a MOS gated, logic level device,
engineered for use as a coil driver in automotive ignition circuits.
    The HGT1S14N40G3VLS is a 400V/14A 300mJ device featuring an increased
clamp voltage of 400V to meet the requirements of coil on plug applications.
Coil on plug systems integrate pencil coils into the spark plug fixture.
Enabling this integration requires a reduction in the overall size of the
coils, typically achieved by reducing the coil turn ratio.  Clamp voltage must
be increased to maintain the energy level necessary to trigger a spark
ignition with a reduced coil turn ratio.
    The device successfully completed qualifications according to the latest
automotive standards.  Special attention was paid to repetitive self clamped
inductive switching (SCIS) life testing under open secondary conditions.  The
HGT1S14N40G3VLS features an active voltage clamp between the collector and the
gate, providing SCIS capability in ignition circuits.  Internal diodes provide
electrostatic discharge (ESD) protection for the logic level gate, and both a
series resistor and a shunt resistor are provided in the gate circuit.
    "Intersil has years of field experience designing IGBTs for automotive
ignition applications, and we have proven that we can deliver high quality in
large volumes," said Peter Blumenroether, marketing manager for automotive
discretes at Intersil.  "It's no coincidence that as Intersil continues to
develop and introduce more advanced IGBTs, the company increases its market
share.  Customers trust our devices in their applications, and count on
Intersil as a development partner for their future ignition system designs.
Intersil is continuously investing in new technology and product development
for automotive ignition applications, and expects to release devices with
clamp voltages of 410V and 450V later this year."

    Pricing and Availability
    The HGT1S14N40G3VLS is immediately available in the TO263 package for high
volume production and is individually priced at $2.28 each in 1000-piece
quantities.
