Product details
Overview
ES3FB R5G from Taiwan Semiconductor is a 400V, 3A super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.98V forward voltage at 3A/25°C, and 100A surge current capability - deployed in high-frequency switching power supplies and LED drivers.
For engineers reviewing the ES3FB R5G datasheet, ES3FB R5G pinout, ES3FB R5G application, or ES3FB R5G equivalent, key selection criteria include VRRM = 400V, IF = 3A, trr = 35ns, thermal resistance RθJA = 84°C/W, and SMB package compatibility with automated SMT assembly.
Technical Context
This discrete silicon rectifier uses a glass-passivated PN junction optimized for high-efficiency SMPS operation. Its super-fast recovery (trr ≤ 35ns) minimizes switching losses in 50–500 kHz converters, while the low-profile DO-214AA package supports dense PCB layouts and reflow-compatible lead finish.
The device operates across –55°C to +150°C junction temperature range, with 10µA max reverse leakage at 25°C and 100µA at 125°C. Junction-to-lead thermal resistance of 24°C/W enables effective heat transfer to copper pads under continuous 3A conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage before breakdown; defines safe operating ceiling in bridge or flyback clamp circuits |
| IF | 3 A - average forward current rating; supports continuous output stages in 30–60W AC/DC adapters |
| trr | 35 ns - reverse recovery time; enables efficient operation up to ~500 kHz without excessive diode switching loss |
| VF @ 3A, 25°C | 0.98 V - forward voltage drop; contributes ~2.94W conduction loss at full load, requiring thermal pad design |
| CJ @ 4V, 1MHz | 41 pF - junction capacitance; limits high-frequency noise coupling and affects EMI filter design in PFC stages |
| RθJA | 84 °C/W - junction-to-ambient thermal resistance on 10mm × 10mm Cu pad; determines required board copper area for thermal management |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode indicated by band, polarity-critical for series/bridge configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node return) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or capacitor positive; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and moisture resistance (MSL Level 1), eliminating need for conformal coating in humid environments |
| Super-fast recovery (trr ≤ 35ns) | Reduces reverse recovery charge (Qrr) and associated switching loss in high-frequency DC/DC converters |
| DO-214AA (SMB) package | Enables automated pick-and-place placement and supports 3A current with minimal footprint (4.5 × 3.2 mm) |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives for environmentally regulated industrial and consumer electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH04-M3/45 | VRRM = 400V, IF = 3A, trr = 35ns, same DO-214AA package but 0.93V VF @ 3A/25°C | Slightly lower forward drop improves light-load efficiency; identical thermal profile and surge rating | Preferred where <0.1V VF reduction justifies dual-sourcing |
| ON Semiconductor MUR340G | VRRM = 400V, IF = 3A, trr = 50ns, DO-201AD package (larger, axial-leaded) | Slower recovery increases switching loss above 200 kHz; through-hole mounting requires different PCB layout | Only suitable for legacy through-hole designs or lower-frequency (<150 kHz) applications |
Compared with VS-3EYH04-M3/45 and MUR340G, ES3FB R5G offers identical voltage/current ratings and recovery speed to the Vishay part but with Taiwan Semiconductor's MSL Level 1 moisture sensitivity and halogen-free construction, while differing from MUR340G in package type, thermal performance, and frequency suitability.

FAQ
What is the maximum junction temperature rating for ES3FB R5G?
The ES3FB R5G has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This allows reliable use in enclosed industrial enclosures or high-ambient environments when mounted on a 10mm × 10mm copper pad per datasheet test conditions. Thermal derating must be applied above 75°C ambient to maintain safe TJ for ES3FB R5G.
Does ES3FB R5G support automated SMT placement?
Yes, ES3FB R5G is qualified for automated surface-mount placement. Its DO-214AA (SMB) package features matte tin-plated leads compliant with J-STD-002 solderability standards and MSL Level 1 moisture sensitivity per J-STD-020 - enabling uninterrupted reflow processing without baking. The low-profile design also prevents tombstoning during reflow for ES3FB R5G.
What is the reverse leakage current of ES3FB R5G at elevated temperature?
At 125°C junction temperature and rated reverse voltage (400V), ES3FB R5G exhibits a maximum reverse leakage current (IR) of 100 µA. At 25°C, it is limited to 10 µA. These values are measured under pulse conditions (PW = 30 ms) and define worst-case DC blocking performance in high-temperature power supply hold-up or standby circuits using ES3FB R5G.
Is ES3FB R5G halogen-free and RoHS compliant?
Yes, ES3FB R5G meets both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. Full compliance documentation is available upon request for ES3FB R5G.
What is the surge current rating for ES3FB R5G?
ES3FB R5G is rated for a non-repetitive peak forward surge current (IFSM) of 100 A, tested per 8.3 ms single half-sine wave per JEDEC standards. This enables robust handling of inrush currents during cold-start or output short-circuit events in power supplies where ES3FB R5G serves as the output rectifier.
