Bipolar transistors help shrink portable designs
Diodes has introduced what it says are the industry's first small signal bipolar transistors to be provided in the miniature DFN0806-3 package.
With a footprint of 0.48mm2 and an off-board profile of only 0.4mm, the devices are claimed to be 20% smaller than equivalent DFN1006, SOT883 and SOT1123 parts.
Targeted at smartphone, tablet and other space-critical portable product designs, they have a 400mW power dissipation capability.
Two complementary pairs of NPN and PNP transistors are initially being introduced by Diodes in the DFN0806-3 package, with pre-biased (digital) transistors to follow.
The NPN MMBT3904FA and PNP MMBT3906FA transistors are 40V VCE rated, handle a continuous current of 200mA and support a 500mA peak pulse current.
The NPN BC847BFA and PNP BC857BFA devices are 45V rated and have continuous current and pulse current handling capabilities of 100mA and 200mA, respectively.
