What are the key features of BYT3400B?
- Fast recovery time minimizes switching losses at high frequencies in SMPS and inverter circuits handling up to 400 V reverse voltage
- Low forward voltage maximum 1.5 V reduces conduction losses, improving efficiency in rectifier bridge and freewheeling diode applications
- Low-noise silicon design suitable for sensitive power conversion stages where EMI from the rectifier stage must be minimized
What is BYT3400B used for?
The BYT3400B is used as an output rectifier or freewheeling diode in switched-mode power supplies and DC-DC converters operating up to 400 V. Its fast recovery characteristic reduces reverse-recovery switching losses in half-bridge and full-bridge topologies, improving efficiency at frequencies above 50 kHz. Industrial motor drive snubber circuits and UPS systems also use this diode to handle transient voltage spikes and provide reliable rectification under high forward current conditions.

Frequently Asked Questions
Which rectifier limits define BYT3400B selection?
The fast-recovery diode is rated for 3 A forward current and 400 V reverse voltage, with a listed maximum forward drop of 1.5 V.
Can this diode be used in switching power conversion?
Its fast-recovery and low-noise characteristics suit relevant converters, but designers should verify switching loss and recovery behavior at the intended 3 A load.
For PCB and sourcing approval, what package details matter?
The device uses a 2-pin through-hole package, so lead spacing, polarity, cathode marking, thermal mounting, and traceable manufacturer labeling require confirmation.
