Product Description
This medium voltage fast recovery diode page covers the 200V to 600V range used across many adapter supplies, lighting drivers and industrial auxiliary power boards. You can compare FR104-FR106, UF4004-UF4006, HER105-HER107 and ES1G by recovery time, reverse voltage, current, package, surge rating and assembly method. This range is often the practical middle ground between low-voltage FRDs and 1000V class parts. Lian Tuo helps you choose enough margin without making the replacement larger or faster than the circuit needs. That gives the buyer a practical middle-ground option.

Find The Middle Ground
A medium voltage fast recovery diode is often the sensible choice when a low-voltage part lacks margin but a 1000V diode is unnecessary. The 200V to 600V range fits many offline auxiliary and driver circuits. Choose from actual reverse stress, not habit. It also keeps the quote connected to the supply your team is building.
Compare Families Carefully
FR104-FR106, UF4004-UF4006 and HER105-HER107 may overlap in voltage but differ in speed, loss and package behavior. A medium voltage fast recovery diode should be selected by waveform, recovery need and board temperature, not only by voltage number. That gives the buyer a practical middle-ground option. It also keeps the quote connected to the supply your team is building.
Protect Production Layouts
Adapter and lighting boards often keep fixed footprints for several product cycles. A medium voltage fast recovery diode replacement should match lead spacing or SMD land pattern before it is approved. That keeps sourcing changes from forcing board changes. It also keeps the quote connected to the supply your team is building.
Review Surge And Heat
Switching supplies can create repeated pulses that stress the diode beyond average current. Lian Tuo can help compare surge rating, recovery time and package heat path so the medium voltage fast recovery diode sample has practical operating margin. That gives the buyer a practical middle-ground option. It also keeps the quote connected to the supply your team is building.
Vertical Product Applications
Adapter Power Supplies
Use a medium voltage fast recovery diode in adapter supplies when 200V to 600V reverse margin and moderate recovery speed are both needed. The chosen model should fit the existing package and thermal space before entering production approval. It also keeps the quote connected to the supply your team is building.
LED Lighting Drivers
LED lighting drivers run in warm housings and often need practical FRD choices for auxiliary or clamp positions. A medium voltage fast recovery diode should be checked for recovery loss, surge and enclosure temperature before samples are released. That gives the buyer a practical middle-ground option. It also keeps the quote connected to the supply your team is building.
Industrial Auxiliary Power
Industrial auxiliary power boards need reliable replacement paths across long service periods. A medium voltage fast recovery diode gives common voltage coverage without jumping to oversized parts. Confirm model family and package before building maintenance stock. It also keeps the quote connected to the supply your team is building. That gives the buyer a practical middle-ground option.
FAQ
When should I use a medium voltage fast recovery diode?
Use it when your circuit needs 200V to 600V reverse rating with recovery faster than a general rectifier. This range is common in adapters, lighting drivers and industrial auxiliary supplies. It also keeps the quote connected to the supply your team is building.
What models are common from 200V to 600V?
Common references include FR104-FR106, UF4004-UF4006, HER105-HER107 and ES1G. The right model depends on recovery speed, current, package, board heat and how much voltage margin your design needs. That gives the buyer a practical middle-ground option. It also keeps the quote connected to the supply your team is building.
Can FR106 replace UF4006?
Not automatically. FR106 and UF4006 may share voltage class, but recovery speed and switching loss can differ. Check the circuit frequency and heat condition before approving a slower or faster replacement. It also keeps the quote connected to the supply your team is building.
Why is 600V common in power supplies?
Many offline or auxiliary circuits see higher reverse stress than their output voltage suggests. A 600V diode gives useful margin in common supply designs, but the exact rating should still follow measured or calculated stress. That gives the buyer a practical middle-ground option.
What data helps quote medium-voltage FRDs?
Send voltage, current, recovery-time target, package, old model, circuit role and quantity. If the product runs warm, include temperature notes so leakage and heat margin can be reviewed. It also keeps the quote connected to the supply your team is building.
Should I choose HER or UF series?
It depends on recovery speed, loss, package and availability. HER parts may fit some efficiency-focused axial needs, while UF parts are often compared for faster recovery. The circuit role decides the better direction. That gives the buyer a practical middle-ground option.
Can Lian Tuo support 200V-600V equivalents?
Yes. We can compare FR, UF, HER and SMD medium voltage fast recovery diode options by rating, speed, package and sourcing practicality before recommending samples. It also keeps the quote connected to the supply your team is building. That gives the buyer a practical middle-ground option.
