Zetex Bipolar transistor value propositions
In saturated switching applications
“Smallest, low loss switches”
In pulsed linear operation, gate driving
“Smallest, highest current drivers”
In linear operation
“Smallest, high dissipation switches”
Be aware of inferior alternatives being offered
• Power Dissipation at different conditions
• Continuous Current x Vce(sat) higher than package Pd

Why do customers use Zetex transistors?
Understanding Our Product Value
Propositions
www.zetex.com
Why do customers use Zetex transistors?
 There are 3 areas where we can clearly demonstrate a benefit from
Zetex transistors
– When used as a Saturated Switch
– When used in pulse linear mode
– When used as a linear switch
 Depending how the transistor is to be used the product needs to be
promoted differently
i.e. different attributes need to be highlighted if the transistor is to be used
as a Gate Driver as opposed to a Motor driver

Saturated switching - circuit requirements
”Smallest, low loss switches”
Improved efficiency by:
• Reducing on state loss
• Reduced drive requirements
• Reduced switching loss
Cost effective solution:
• Reduced heat generation allowing smaller package
• Reduced heat generation requires less copper area
11

Zetex references to grow market share
 Released improved version of ZTL431 in SC70-6 and Used in power supplies
SOT23 and ZTL432 in SOT23
>= 5V
– Allows us to be market price competitive
Competes aggressively
– Allows us to grow market share
against TL431 in SOT23
– 20V stops us being used in notebook adapters
– Can offer in other packages but need high volume
 Released ZTLV431 (~ TLV431) in SOT23
– Market price competitive
– Smaller die version will allow other packages
 Released LM4040 and LM4041 in SOT23
– These command higher ASP than TL431
– All variants are in 1% and 0.5% tolerances
– Market price competitive
– Future die shrinks will allow SC70-5 variants
Used in low voltage

In summary for standard IC’s
 Tremendous potential revenue growth on current monitors
– All are design registerable
– Strong value propositions
• “Simplest Short-Circuit Detector”
• “3-pin sensing with low-side output”
• “Simplest, lowest IQ Gas-Gauge”
 Grow share of industry standard references and shunt regulators
