Product details
Overview
FES1DE from Diodes Incorporated is a 1.0A, 200V ultra-fast recovery surface-mount rectifier in DO-219AA package, featuring 25ns reverse recovery time, 0.92V max forward voltage at 1A, and 5µA max reverse leakage at 200V/25°C. It serves as a boost diode in PFC stages and secondary-side freewheeling diode in high-frequency DC-DC converters for flat-panel displays and LED lighting.
For engineers reviewing the FES1DE datasheet, FES1DE pinout, FES1DE application, or FES1DE equivalent, key selection criteria include ultra-fast switching (tRR = 25 ns), low VF (0.92 V) for thermal efficiency, DO-219AA footprint compatibility, and operation up to +150°C junction temperature in compact power supplies.
Technical Context
The FES1DE employs glass-passivated silicon die optimized for high-speed switching in AC-AC and DC-DC topologies. Its 25 ns reverse recovery time enables efficient operation in >100 kHz converters, while the 55°C/W junction-to-case thermal resistance supports high-power-density layouts with minimal heatsinking.
Designed for commercial-grade reliability, it delivers stable performance across –55°C to +150°C operating range and maintains <5 µA IR at rated VRRM, reducing standby losses in energy-sensitive consumer power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Blocks up to 200 V reverse voltage without breakdown in PFC or output rectification |
| IO | 1.0 A - Continuous average forward current rating at +25°C ambient, derated above 25°C |
| VF Max | 0.92 V @ 1 A - Low conduction loss enabling >92% efficiency in 12 V output buck converters |
| tRR | 25 ns - Ultra-fast recovery minimizes switching loss and EMI in >100 kHz SMPS designs |
| IR Max | 5 µA @ 200 V / 25°C - Low leakage preserves hold-up time and reduces no-load power in standby mode |
| TJ Range | –55°C to +150°C - Enables deployment in thermally constrained LED drivers and display power modules |
| RθJC | 55°C/W - Allows direct thermal coupling to PCB copper for passive cooling in space-limited applications |
Pinout & Package
DO-219AA surface-mount package: 2-terminal, cathode-banded, low-profile (max height 3.90 mm), green molding compound (UL 94V-0), matte tin-plated copper leadframe. Weight: 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switch node or transformer secondary in flyback/freewheeling paths |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; polarity marking ensures correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enhances long-term reliability under thermal cycling and humidity exposure in consumer power modules |
| Superfast 25 ns tRR | Reduces turn-off loss and ringing in high-frequency synchronous rectifiers and PFC boost stages |
| Low 0.92 V VF | Lowers I²R heating at 1 A, permitting smaller copper area and eliminating need for thermal vias in cost-sensitive designs |
| DO-219AA footprint | 0.60 mm lead length and 2.80 mm body width enable dense layout in slim-profile adapters and LED drivers |
| RoHS 3 & Halogen-free | Meets EU environmental compliance (Br+Cl <1500 ppm, Sb <1000 ppm) for global consumer electronics shipments |
Applications
| Flat Panel Display Power | USB-C PD Charger Output Stage |
|---|---|
Use Scenario: Secondary-side rectification in 24–48 V boost-derived backlight inverters for LCD TVs. IC Role / Device Role / Timing Role: Freewheeling diode in active clamp flyback, conducting during MOSFET off-time with 25 ns recovery. Use Value: Low VF (0.92 V) limits conduction loss to <0.92 W at 1 A, maintaining <50°C case temperature without heatsink. | Use Scenario: Output rectifier in 20 V/3 A GaN-based USB-C PD 3.0 charger. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in CCM flyback, handling 100–200 kHz switching with minimal reverse recovery tail. Use Value: 25 ns tRR prevents cross-conduction loss with GaN FETs, improving full-load efficiency by 0.8% vs. standard FRD. |
| LED Driver Freewheeling | Industrial DC-DC Converter Snubber |
Use Scenario: Freewheeling path in 36 V input, 700 mA constant-current buck LED driver for streetlights. IC Role / Device Role / Timing Role: Provides low-loss current path during inductor discharge phase; operates continuously at +105°C ambient. Use Value: 150°C TJ rating and 5 µA IR at 125°C ensure stable regulation over lifetime without thermal runaway. | Use Scenario: Clamp diode in RCD snubber network of 48 V input, 12 V/10 A isolated forward converter. IC Role / Device Role / Timing Role: Absorbs leakage inductance energy during primary switch turn-off; requires fast recovery to avoid voltage overshoot. Use Value: 25 ns tRR limits peak clamp voltage to <320 V, allowing use of 350 V-rated capacitor instead of 400 V part. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02 | Same 200 V VRRM, 1 A IO, but tRR = 35 ns; VF = 0.95 V; TO-277A package (larger footprint) | Higher tRR increases switching loss in >150 kHz designs; TO-277A requires 30% more board area than DO-219AA | Select when legacy TO-277A layout exists and 35 ns recovery is acceptable for <120 kHz operation |
| MBR120LSFT1G | Schottky structure: VF = 0.45 V, but VRRM = 20 V only; not suitable for 200 V blocking | Cannot replace FES1DE in PFC or 24–48 V output stages due to low breakdown voltage | Use only in low-voltage (<24 V) freewheeling where ultra-low VF outweighs voltage limitation |
Compared with STTH1R02 and MBR120LSFT1G, the FES1DE uniquely balances 200 V capability, 25 ns speed, and DO-219AA miniaturization-making it optimal for space-constrained, high-frequency consumer power supplies where both voltage rating and recovery speed are critical.

FAQ
What is the maximum junction temperature and how does it affect PCB layout?
The FES1DE has a maximum junction temperature of +150°C. Its 55°C/W junction-to-case thermal resistance means that with 1 A forward current and 0.87 V typical VF, ~0.87 W of power dissipation requires ≥100 mm² of 2-oz copper connected directly to the cathode/anode pads. Thermal vias under the leads further reduce steady-state TJ by up to 12°C.
Is FES1DE suitable for automotive applications?
The FES1DE is qualified for commercial temperature range (–55°C to +150°C) and is not AEC-Q101 qualified. For automotive use, Diodes offers the FES1DEQ variant-identical electrical specs but manufactured in IATF 16949 facilities with PPAP support and AEC-Q101 stress testing per the separate datasheet DS43132Q.
How does the DO-219AA package compare to SMA in size and thermal performance?
DO-219AA measures 2.80 mm × 1.90 mm × 3.80 mm (L×W×H), ~35% smaller in footprint than SMA (4.5 mm × 2.7 mm). Its RθJC of 55°C/W is 18% lower than typical SMA-packaged ultra-fast diodes (67°C/W), due to shorter internal bond wires and direct copper leadframe contact-enabling higher power density in slim-profile adapters.
Can FES1DE replace a standard FR107 in an existing design?
Yes, FES1DE can replace FR107 in most cases: both are 1 A/1000 V devices, but FES1DE offers superior performance-25 ns vs. 500 ns tRR, 0.92 V vs. 1.3 V VF, and DO-219AA vs. DO-41. However, verify PCB pad layout compatibility and confirm that the lower VF does not cause control loop instability in voltage-mode PFC controllers relying on diode drop for sensing.
