Product Description
This high voltage fast recovery diode page supports circuits where reverse-voltage stress is high and standard rectifier recovery is too slow. You can compare FR107, UF4007, HER108, MUR1600 and power-package FRDs by voltage class, recovery speed, current, surge rating, package insulation and heat path. The 600V to 1200V range is common in PFC boost, inverter, high-voltage SMPS and clamp positions. Lian Tuo helps you choose parts that match both the bus voltage and the switching behavior. That helps avoid a high-voltage part that is only correct on paper.

Respect High-Bus Stress
A high voltage fast recovery diode should be selected from bus voltage, ringing, clamp behavior and derating margin. In PFC or inverter circuits, reverse stress can be much higher than a simple DC label. Share the waveform or design limit before samples are chosen. It also makes sample review easier when the bus waveform is demanding.
Choose Recovery By Heat
FR107, UF4007 and HER108 may share a voltage class, but their recovery behavior can produce different heat and switching stress. A high voltage fast recovery diode should match circuit frequency and loss target, not only the 1000V number printed in the model. That helps avoid a high-voltage part that is only correct on paper.
Check Package Insulation
High-voltage power packages need creepage, insulation and heat-sink details reviewed before approval. Axial parts may be simple for small currents, while MUR-style packages need hardware checks. The high voltage fast recovery diode package must fit the electrical and mechanical environment. It also makes sample review easier when the bus waveform is demanding.
Build Realistic Replacements
High-voltage FRD replacements often fail when buyers compare only voltage and current. Lian Tuo can review recovery time, package, surge rating and circuit role before suggesting alternates. This keeps repair and OEM orders from approving parts that are only superficially similar. That helps avoid a high-voltage part that is only correct on paper.
Vertical Product Applications
PFC Boost Circuits
Use a high voltage fast recovery diode in PFC boost circuits when reverse-voltage margin and recovery behavior both affect efficiency. The selected part should match bus voltage, switching frequency and heat path. Confirm whether silicon FRD or SiC is the better route. It also makes sample review easier when the bus waveform is demanding.
Inverter Power Boards
Inverter power boards can expose diodes to high voltage, sharp transitions and warm operation. A high voltage fast recovery diode should be reviewed for recovery speed, surge and package insulation. That keeps the choice reliable under real switching stress. That helps avoid a high-voltage part that is only correct on paper.
High-Voltage SMPS
High-voltage SMPS positions need diodes that handle spikes without adding avoidable switching loss. A 600V to 1200V high voltage fast recovery diode can fit clamp or rectifier roles when voltage margin and package heat path are checked early. It also makes sample review easier when the bus waveform is demanding.
FAQ
When should I use a high voltage fast recovery diode?
Use it when the circuit needs 600V to 1200V reverse rating and faster recovery than a standard rectifier. It is common in PFC, inverter, high-voltage SMPS and clamp positions. It also makes sample review easier when the bus waveform is demanding.
Is UF4007 better than FR107?
UF4007 is faster, but better depends on the circuit. If recovery loss or waveform stress matters, UF4007 may help. If the circuit only needs standard fast recovery, FR107 can be more practical. That helps avoid a high-voltage part that is only correct on paper.
When should I consider 1200V instead of 1000V?
Consider 1200V when bus voltage, spikes or derating rules leave too little margin for 1000V parts. The higher rating should be supported by real stress conditions, not chosen automatically. It also makes sample review easier when the bus waveform is demanding.
Can high voltage FRDs replace SiC diodes?
Sometimes, but SiC parts have different recovery behavior and switching loss. If the original design used SiC for efficiency or heat, a silicon high voltage fast recovery diode may not be a safe replacement without testing. That helps avoid a high-voltage part that is only correct on paper.
What data helps quote high-voltage FRDs?
Send voltage, current, recovery-time target, package, bus voltage, topology, target model and quantity. Waveform or heat data is useful for PFC, inverter and high-voltage SMPS projects. It also makes sample review easier when the bus waveform is demanding. That helps avoid a high-voltage part that is only correct on paper.
Why does package insulation matter here?
High-voltage packages may need insulation from heat sinks or nearby hardware. Creepage, clearance and mounting materials affect safety and heat transfer. Review these details before approving power-package FRDs. That helps avoid a high-voltage part that is only correct on paper.
Can Lian Tuo support 600V-1200V equivalents?
Yes. We can compare FR107, UF4007, HER108, MUR1600 and 1200V fast recovery diode options by voltage, speed, package and application stress before recommending samples. It also makes sample review easier when the bus waveform is demanding. That helps avoid a high-voltage part that is only correct on paper.
