Product details
Overview
ES1G R3G from Taiwan Semiconductor is a 1 A, 400 V super fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 1 A and 25°C, and 5 µA max reverse leakage at rated VR and 25°C, used in DC-DC converters and snubber circuits.
For engineers reviewing the ES1G R3G datasheet, ES1G R3G pinout, ES1G R3G application, or ES1G R3G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), forward surge current rating (30 A), junction-to-lead thermal resistance (35 °C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This single-die silicon rectifier uses glass passivated junction technology to achieve super fast switching performance with low forward voltage drop and minimal reverse recovery charge. Its DO-214AC (SMA) package supports automated placement and meets UL 94V-0 flammability requirements.
The device operates across -55°C to +150°C junction temperature range, delivers 1 A average forward current with derating above 75°C, and exhibits 18 pF typical junction capacitance at 1 MHz and 4.0 V reverse bias - critical for high-frequency switching efficiency in SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage headroom in flyback or buck-derived topologies |
| IF(AV) | 1 A - continuous average forward current capability at 75°C case temperature; sets baseline conduction rating for power stage sizing |
| trr | 35 ns - measured under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation up to ~3 MHz switching frequencies |
| VF(max) | 1.30 V @ 1 A, 25°C - forward voltage drop directly impacts conduction loss and thermal design in high-duty-cycle applications |
| RθJL | 35 °C/W - junction-to-lead thermal resistance; determines temperature rise from die to PCB pad under steady-state conduction |
| IR(max) | 5 µA @ 400 V, 25°C - low leakage ensures minimal standby power loss in offline auxiliary supplies |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode indicated by molded band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in boost/flyback); polarity must align with schematic symbol |
| Cathode | Forward current exit / reverse blocking terminal | Marked by visible band; ties to higher-potential rail (e.g., output capacitor positive) in freewheeling paths |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable electrical parameters over time and humidity exposure; eliminates need for conformal coating in industrial environments |
| Super fast recovery (35 ns) | Reduces switching losses and EMI generation compared to standard rectifiers; supports >500 kHz SMPS designs |
| J-STD-020 Level 1 moisture sensitivity | Allows unlimited floor life before reflow; eliminates baking requirement and simplifies SMT line logistics |
| RoHS & halogen-free compliance | Fulfills IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; required for CE-marked industrial and consumer end equipment |
Applications
| DC–DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V/1 A flyback converter powering industrial sensors. IC Role / Device Role / Timing Role: Freewheeling rectifier conducting during transformer reset phase; handles 1 A average current with <1.3 V conduction loss. Use Value: 35 ns trr minimizes reverse recovery spikes that would otherwise stress primary MOSFET and increase EMI filter size. | Use Scenario: RC snubber network across MOSFET drain-source in 24 V input buck converter operating at 300 kHz. IC Role / Device Role / Timing Role: Clamp diode absorbing turn-off energy; conducts brief high-di/dt pulses during switching transitions. Use Value: Low VF and fast trr ensure rapid clamping action with minimal voltage overshoot and reduced snubber resistor dissipation. |
| Lighting Application | Switching Inverter |

IC Role / Device Role / Timing Role: Provides low-loss return path for inductive current when upper switches turn off; handles 30 A non-repetitive surge during fault events. Use Value: 30 A IFSM rating ensures robustness against motor stall currents without bond wire fusing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | Same 400 V VRRM and 1 A IF, but 50 ns trr and 1.35 V VF max; TO-220AC package | Requires through-hole mounting and heatsinking; unsuitable for space-constrained SMT designs | Select only if board layout allows TO-220 footprint and thermal mass supports higher VF-related losses |
| MBR140 | 40 V VRRM, Schottky structure, 0.55 V VF max; same DO-214AC package | Cannot replace in 400 V systems due to insufficient blocking voltage; limited to low-voltage DC-DC outputs | Use only in ≤40 V secondary-side rectification where ultra-low VF outweighs voltage limitation |
Compared with STTH1R04 and MBR140, ES1G R3G uniquely balances 400 V blocking, 35 ns speed, and SMT-compatible DO-214AC packaging - making it optimal for compact, high-efficiency 24–48 V input SMPS where both voltage margin and switching loss matter.

FAQ
What is the maximum repetitive peak reverse voltage rating for ES1G R3G?
The ES1G R3G has a maximum repetitive peak reverse voltage (VRRM) rating of 400 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version O2112). It defines the highest reverse voltage the diode can block repeatedly without breakdown under normal operating conditions. Exceeding this voltage risks avalanche failure or permanent damage to the ES1G R3G junction.
What is the forward voltage drop of ES1G R3G at 1 A and 25°C?
The ES1G R3G exhibits a maximum forward voltage (VF) of 1.30 V when conducting 1 A at 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss. At elevated temperatures or higher currents, VF may increase slightly, but remains within design margins for typical SMPS applications using the ES1G R3G.
Does ES1G R3G have a defined reverse recovery time, and how is it measured?
Yes, ES1G R3G has a specified reverse recovery time (trr) of 35 ns maximum. It is measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the Electrical Specifications section. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking, directly impacting switching losses and EMI in high-frequency converters using the ES1G R3G.
What package type does ES1G R3G use, and what are its key mechanical features?
The ES1G R3G uses the DO-214AC (SMA) surface-mount package. Key mechanical features include glass-molded construction meeting UL 94V-0 flammability rating, matte tin-plated leads compliant with J-STD-002 solderability, JESD 201 Class 2 whisker resistance, and polarity indicated by a visible cathode band. Its weight is approximately 0.060 g, and it supports automated placement per the ES1G R3G product documentation.
Is ES1G R3G compliant with environmental regulations such as RoHS and halogen-free standards?
Yes, ES1G R3G is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. These compliance statements appear in the FEATURES section of the official Taiwan Semiconductor datasheet (Version O2112). The halogen-free status confirms absence of chlorine and bromine-based flame retardants, while RoHS compliance certifies restriction of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE - all verified for the ES1G R3G production lot.
