Product details
Overview
FES1DE-7 from Diodes Incorporated is a 1.0A, 200V ultra-fast surface-mount rectifier in DO-219AA package, optimized as a boost diode in PFC circuits and for secondary rectification/freewheeling in high-frequency DC-DC converters. It delivers 25ns reverse recovery time, 0.92V max forward voltage at 1A, and 5µA max reverse leakage at 200V and +25°C, enabling high-efficiency operation in flat-panel display power supplies.
For engineers reviewing the FES1DE-7 datasheet, FES1DE-7 pinout, FES1DE-7 application, or FES1DE-7 equivalent, key selection criteria include ultra-fast recovery (25ns), low VF (0.92V), thermal resistance (RθJA = 115°C/W), RoHS/Green compliance, and DO-219AA package compatibility with space-constrained consumer power designs.
Technical Context
The FES1DE-7 employs glass-passivated silicon die to achieve stable reverse blocking up to 200V and sub-30ns recovery performance under IF = 0.5A / IR = 1.0A conditions. Its junction-to-lead thermal resistance of 45°C/W supports reliable operation at TJ up to +150°C in thermally dense layouts.
Designed for high-switching-frequency topologies, it maintains low capacitance (20pF at 4V/1MHz) and minimal stored charge, reducing switching losses in PFC boost stages and synchronous rectifier freewheel paths where fast turn-off minimizes cross-conduction risk.

FAQ
What is the maximum junction temperature for continuous operation?
The FES1DE-7 has an operating junction temperature range of -55°C to +150°C. For continuous 1A DC operation, thermal design must ensure junction temperature remains ≤+150°C using the specified RθJA = 115°C/W and appropriate PCB copper area or airflow.
Is the FES1DE-7 suitable for automotive applications?
No-the FES1DE-7 is commercial-grade. An automotive-qualified version, FES1DEQ, is available separately and qualified to AEC-Q101 with PPAP capability and IATF 16949 manufacturing.
How does the DO-219AA package compare to SMA in thermal performance?
DO-219AA offers lower RθJL (45°C/W) than SMA (typically ~60°C/W) due to its exposed lead-frame structure, improving heat transfer to PCB copper. Its smaller footprint and 0.6mm height also reduce board space versus SMA's 2.3mm height.
Can FES1DE-7 replace a standard FR107 in a 65kHz flyback?
Yes-its 25ns tRR and 200V rating exceed FR107's 500ns tRR and 1000V rating, but derating is required: FES1DE-7's lower VRRM (200V vs. 1000V) restricts use to circuits with peak reverse voltage ≤200V, such as low-input-voltage flybacks.
