UPS140e3
1.0 A Schottky Barrier Rectifier
DESCRIPTION
The Microsemi UPS140e3 Powermite
Schottky rectifier is RoHS
compliant and offers optimized forward voltage characteristics with reverse
blocking capabilities up to 40 Volt. They are ideal for surface mount
applications that operate at high frequencies.
In addition to its size advantages, Powermite
package features include a
full metallic bottom that eliminates possibility of solder flux entrapment
during assembly, and a unique locking tab acts as an efficient heat path
from die to mounting plane for external heat sinking with very low thermal
resistance junction to case (bottom). Its innovative design makes this
device ideal for use with automatic insertion equipment.

Options for screening in accordance with
MIL-PRF-19500 for JAN, JANTX, JANTXV,
and JANS are available by adding MQ, MX,
MV, or MSP prefixes respectively to part
numbers. For example, designate
MXUPS140e3 for a JANTX (consult factory
for Tin-Lead plating).
Optional 100% avionics screening available
by adding MA prefix for 100% temperature
cycle, thermal impedance and 24 hours
