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
9
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

”Smallest, low loss switches”
Saturated switching - circuit requirements
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
