Product details
Overview
FES2DE-7 from Diodes Incorporated is a 2.0A, 200V ultra-fast surface-mount rectifier in DO-219AA package, optimized for boost-stage PFC and secondary-side rectification in high-frequency DC-DC converters. It delivers 25ns reverse recovery time, 0.92V max forward voltage at 2A, and 5µA max reverse leakage at 200V/25°C - enabling high-efficiency operation in compact LED drivers and flat-panel display power supplies.
For engineers reviewing the FES2DE-7 datasheet, FES2DE-7 pinout, FES2DE-7 application, or FES2DE-7 equivalent, key selection criteria include ultra-fast tRR (25ns), low VF (0.92V), thermal resistance (RθJA = 70°C/W), RoHS/Green compliance, and DO-219AA footprint compatibility with space-constrained consumer power designs.
Technical Context
The FES2DE-7 employs glass-passivated silicon die to achieve stable reverse characteristics up to 150°C junction temperature and supports repetitive surge current of 50A (8.3ms half-sine). Its 32pF typical junction capacitance at 4V/1MHz enables minimal switching loss in >100kHz topologies.
Designed for freewheeling and output rectification in AC-AC and DC-DC converters, it operates reliably under high-temperature conditions (–55°C to +150°C) with cathode-band polarity marking and matte tin-plated copper lead-frame for MIL-STD-202-compliant solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200V - blocks full AC line transients in universal-input SMPS without breakdown |
| IO (AV) | 2.0A - sustains continuous output current in 15–30W LED drivers and charger secondaries |
| tRR | 25ns - minimizes switching losses and EMI in 200–500kHz PFC and LLC stages |
| VF (max) | 0.92V @ 2A - reduces conduction loss to ≤1.84W, easing thermal design in sealed enclosures |
| IR (max) | 5µA @ 200V/25°C - ensures low standby power in always-on display bias rails |
| RθJA | 70°C/W - allows 2A operation at +85°C ambient on standard 1-in² FR4 with 2oz copper |
| Package | DO-219AA - 1.90mm × 2.80mm footprint fits <2.0mm board height constraints |
Pinout & Package
DO-219AA is a low-profile, surface-mount plastic package with two terminals: anode and cathode. Cathode identified by molded band; terminals are matte tin over copper, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point during forward conduction | Connects to switching node (e.g., MOSFET drain in boost) or transformer secondary center-tap |
| Cathode | Output current exit point during forward conduction | Connects to output capacitor positive rail; marked with visible cathode band on package body |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable IR and V(BR)R across –55°C to +150°C, eliminating passivation-related early-life failure |
| Superfast 25ns tRR | Reduces turn-off energy loss by >40% vs. standard fast recovery diodes in 300kHz PFC circuits |
| Low VF (0.92V) | Lowers I²R heating at 2A, enabling smaller heatsinks or no heatsink in <25°C ambient LED modules |
| DO-219AA package | 0.6mm profile and 1.9×2.8mm footprint support ultra-thin flat-panel display power boards |
| Halogen & antimony free | Meets IEC 61249-2-21:2017 with Br+Cl <1500ppm, supporting EU EcoDesign and Japan J-Moss compliance |
Applications
| Flat Panel Display Power | USB-C PD Charger Secondary |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | Same 200V/2A rating; tRR = 35ns (slower); VF = 0.95V; DO-214AC package (larger, 4.6×2.8mm) | Less suitable for height-constrained designs; higher tRR increases EMI filtering burden | Select if DO-214AC footprint already qualified and 10ns slower recovery is acceptable |
| MBR220LSFT1G | Schottky construction; VF = 0.52V but VRRM = 20V only; unsuitable for 200V blocking | Cannot replace in PFC or primary-side rectification; limited to low-VOUT DC-DC outputs | Only viable where reverse voltage ≤20V and ultra-low VF is prioritized over blocking capability |
Compared with STTH2R02DJF and MBR220LSFT1G, the FES2DE-7 uniquely balances 200V blocking, 25ns speed, and sub-2mm height - making it the only option for thermally demanding, space-limited 200V rectification where Schottky devices fail and larger packages violate mechanical constraints.

FAQ
What is the maximum junction temperature rating for the FES2DE-7?
The FES2DE-7 has an operating junction temperature range of –55°C to +150°C, verified per JEDEC JESD22-A108. Its glass-passivated die and DO-219AA package enable sustained 2A operation at +125°C ambient when mounted on 1-in² 2oz copper with minimal airflow, as confirmed by thermal characterization in DS43133 Rev. 4-2.
Is the FES2DE-7 suitable for automotive applications?
The FES2DE-7 is not AEC-Q101 qualified. Diodes offers the automotive-grade variant FES2DEQ (same electrical specs, AEC-Q101 tested) for under-hood and infotainment systems. FES2DE-7 is intended for consumer-grade applications including displays, chargers, and lighting where extended temperature and qualification are not required.
How does the DO-219AA package compare to SMA in thermal performance?
DO-219AA provides lower RθJA (70°C/W) than standard SMA (typically 90–100°C/W) due to its shorter thermal path and exposed copper lead-frame. In identical PCB layouts, DO-219AA runs ~12°C cooler at 2A, enabling higher power density without added copper area or thermal vias.
Can the FES2DE-7 be used as a freewheeling diode in a 48V DC-DC buck converter?
Yes - with 200V VRRM and 25ns tRR, the FES2DE-7 safely clamps inductive kickback in 48V buck converters switching up to 1MHz. Its 0.92V VF yields lower conduction loss than 100V Schottkys in this voltage range, and its 150°C TJ rating supports operation in enclosed industrial enclosures.
