What is a Schottky diode vs normal?

Like other diodes, the Schottky diode controls the direction of current flow in a circuit. However, unlike standard diodes, the Schottky diode is known for its low forward voltage and fast switching ability. This makes them an ideal choice for radio frequency applications and any device with low voltage requirements.

Are Schottky diodes more expensive?

Schottky diodes are expensive. So, its a trade off among reverse voltage rating, speed, leakage current and price. So, for your case I would really see further down on the requirement of minimum battery voltage needed for the circuit to operate and battery life time expected.

What are the power Schottky diodes used for?

ST’s power Schottky diodes combine low voltage-drop characteristics with negligible or zero recovery. They range from 15 to 200 V and from 1 to 240 A, covering all application needs from low voltage OR-ing and 48 V converters, to higher voltage battery chargers and welding equipment. They are avalanche specified for improved ruggedness.

What can Schottky rectifiers be used for?

Recent 30 V to 60 V dual Schottky rectifiers in PSMC (TO-277A) will be used in automotive grade high-performance DC/DC converters through the integration of rectification and freewheeling diode into the same package, and in enhanced reverse polarity protection functions.

Which is the best package for power Schottky?

New packages such as the SMA Flat , SMB Flat and PSMC packages are encapsulations tailored for power Schottky rectifiers in slim equipment designs. SMA Flat and SMB Flat will be used in LED lighting, battery-powered equipment, consumer and harsh industrial environments power converters.

Are there power Schottky rectifiers for SMB PCB?

In addition, ST’s 40, 60, 100 V and 200V power Schottky rectifiers are now available in the new SMA Flat and SMB Flat packages providing even more power density in 1 mm thick only. They are fully compatible with SMA and SMB PCB footprints and even with SOD128 footprint.
