Frequently Asked Questions
What is the voltage and current rating of the UPS5817E3/TR7 and what circuit function is it primarily designed for?
The UPS5817E3/TR7 is rated for 20 V reverse voltage and 1 A continuous forward current, and is specifically designed as a free-wheeling diode for inductive loads such as motors, relays, and solenoids where low power loss Schottky switching reduces heat dissipation compared to standard PN junction rectifiers.
Why is the Schottky junction of UPS5817E3/TR7 advantageous in high-frequency switching power supply rectification?
The Schottky junction of the UPS5817E3/TR7 has a lower forward voltage drop (typically 0.3 V to 0.4 V) and near-zero reverse recovery time compared to standard PN diodes, which reduces switching losses at frequencies above 100 kHz and improves overall converter efficiency in buck and boost DC-DC topologies.
For a compact motor control PCB, how does the DO-216AA Powermite package of UPS5817E3/TR7 compare in size to a standard SOD-123?
The DO-216AA Powermite package of the UPS5817E3/TR7 is a very small surface-mount outline measuring approximately 1.6 mm x 1.2 mm, which is comparable to SOD-323 micro-packages and smaller than standard SOD-123, enabling tight placement near switching transistors on compact motor control PCBs.
How does the 24-week factory lead time affect procurement planning for UPS5817E3/TR7 in production runs?
With a 24-week factory lead time, procurement teams should place orders approximately 6 months ahead of production start dates and consider maintaining a safety stock of at least 8 weeks of consumption to buffer against supply disruptions, particularly for continuous production programs in automotive or industrial equipment manufacturing.
