Product details
Overview
ES1F R3G from Taiwan Semiconductor is a 1 A, 300 V super fast recovery surface-mount rectifier 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 ES1F R3G datasheet, ES1F R3G pinout, ES1F R3G application, or ES1F R3G equivalent, key selection criteria include repetitive peak reverse voltage (300 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 discrete silicon diode uses a glass-passivated PN junction to achieve super-fast switching performance with low stored charge. Its single-die configuration and DO-214AC package support automated placement and reflow soldering per J-STD-002.
The device operates across -55°C to +150°C junction temperature range, delivers 1 A average forward current with derating above 75°C, and maintains stable reverse characteristics up to 125°C with 100 µA max IR - critical for high-frequency switching and freewheeling in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or clamp circuits |
| IF(AV) | 1 A - continuous forward current rating at TA = 25°C; requires thermal derating above 75°C ambient |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching in SMPS designs |
| VF | 1.30 V max at IF = 1 A, TJ = 25°C - low conduction loss supports high-efficiency 12–48 V output converters |
| RθJL | 35 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour heat sinking without heatsink |
| IR | 5 µA max at VR = 300 V, TJ = 25°C - ensures minimal standby power loss in offline auxiliary supplies |
Pinout & Package
DO-214AC (SMA) surface-mount package with molded epoxy body (UL 94V-0), matte tin-plated leads, cathode band polarity marking, and 0.060 g typical weight.

|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter or transformer secondary) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or clamp capacitor; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Freewheeling path for stored inductor energy when drive signal turns off; must recover before next cycle. Use Value: 35 ns trr prevents cross-conduction in PWM-driven loads; 30 A IFSM withstands repeated inductive kick events without degradation. |
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-ES1FHM3/5A | Same DO-214AC package, 300 V VRRM, but 1.25 V VF typ (vs. 1.30 V max for ES1F R3G); 30 ns trr | Slightly lower conduction loss; preferred where <0.5 W dissipation is critical in thermally constrained layouts | Select VS-ES1FHM3/5A if VF reduction justifies tighter tolerance control and higher unit cost |
| ON Semiconductor ES1F | Identical electrical specs and DO-214AC package; differs only in marking (no "R3G" suffix) and tape/reel packaging (7,500 pcs vs. 10,000 pcs) | No functional difference; suitable for drop-in replacement where reel size or date-code traceability is not mandated | Choose ON Semi ES1F for legacy BOM alignment or distributor stock availability; verify reel quantity match |
Compared with VS-ES1FHM3/5A and ON Semi ES1F, the ES1F R3G offers verified J-STD-020 Level 1 MSL rating and halogen-free compliance per IEC 61249-2-21 - critical for automotive-qualified lighting and industrial control programs requiring full material declarations.

FAQ
What is the maximum junction temperature rating for ES1F R3G?
The ES1F R3G has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This allows use in high-ambient environments such as enclosed LED drivers or industrial power modules. Derating of forward current begins above 75°C ambient, per the forward current derating curve in the ES1A–ES1J datasheet. Thermal design must account for RθJL = 35 °C/W to ensure TJ remains within limit under full load.
Does ES1F R3G meet J-STD-020 moisture sensitivity requirements?
Yes, ES1F R3G is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can be exposed indefinitely to floor life conditions (≤30°C/85% RH) without baking prior to reflow. This eliminates pre-bake steps in standard SMT lines, reducing process complexity and cost. The device's glass-passivated junction and UL 94V-0 molding compound contribute to this robust MSL rating.
What is the reverse recovery time (trr) specification for ES1F R3G?
The ES1F R3G has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed across the ES1F–ES1J subgroup and enables efficient operation in switching power supplies operating up to 500 kHz. The fast trr minimizes switching losses and associated EMI, especially in high-density DC–DC converter designs where layout parasitics are critical.
Is ES1F R3G RoHS and halogen-free compliant?
Yes, ES1F R3G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The device uses halogen-free molding compound and matte tin-plated leads, satisfying environmental requirements for CE-marked consumer electronics, EU medical devices, and telecom infrastructure. Full material declarations and test reports are available upon request for compliance validation.
What does the "R3G" suffix indicate in ES1F R3G?
The "R3G" suffix in ES1F R3G denotes Taiwan Semiconductor's internal packaging and environmental coding: "R" indicates tape-and-reel packaging, "3" specifies 7,500 units per reel, and "G" confirms halogen-free construction. This distinguishes it from non-halogen variants and alternate reel quantities. The core electrical and thermal specifications remain identical to ES1F across all suffix variants.
