Product details
Overview
ES2HA R3G from Taiwan Semiconductor is a 2A, 600V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 1.70V max forward voltage at 2A/25°C, 35ns reverse recovery time, and 20pF junction capacitance - deployed in snubber networks and high-frequency DC-DC converters.
For engineers reviewing the ES2HA R3G datasheet, ES2HA R3G pinout, ES2HA R3G application, or ES2HA R3G equivalent, key selection criteria include repetitive peak reverse voltage (600V), thermal resistance (RθJL = 20°C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and cathode-band polarity marking.
Technical Context
This discrete silicon rectifier uses a glass-passivated PN junction to achieve super-fast recovery (trr ≤ 35 ns) with low stored charge, enabling efficient operation in switching-mode power supplies operating above 100 kHz. Its single-die configuration and DO-214AC package support automated placement and reflow soldering.
The device sustains 50A non-repetitive surge current (8.3 ms half-sine) and operates across –55°C to +150°C junction temperature range. Thermal performance is defined by RθJL = 20°C/W and RθJA = 75°C/W, with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage without breakdown |

| trr | 35 ns - reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions |
| VF | 1.70 V max - forward voltage drop at 2A and 25°C junction temperature |
| RθJL | 20 °C/W - junction-to-lead thermal resistance, critical for heatsinking via PCB copper pour |

Applications
| DC–DC Converter Output Rectification | Snubber Network Clamp Diode |
|---|---|
Use Scenario: High-efficiency 48V-to-12V isolated buck-derived converter in telecom power supply. IC Role / Device Role / Timing Role: Output rectifier conducting during transformer secondary conduction phase; handles 2A average current with minimal conduction loss. Use Value: 1.70V VF and 35ns trr reduce total power loss vs. standard recovery diodes, improving efficiency by ≥0.8% at full load. | Use Scenario: RCD snubber across MOSFET drain-source in 65kHz flyback converter. IC Role / Device Role / Timing Role: Clamp diode that conducts only during MOSFET turn-off transient to absorb leakage inductance energy. Use Value: Low CJ (20 pF) and fast trr minimize capacitive loading and reverse recovery ringing, suppressing voltage overshoot by up to 15V. |

IC Role / Device Role / Timing Role: Primary-side rectifier converting reflected flyback voltage to DC output; blocks 600V reverse stress during MOSFET on-time. Use Value: 600V VRRM provides 2× safety margin over 300V bus, eliminating need for series stacking or derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06U (STMicroelectronics) | Same 2A/600V rating; VF = 1.7V typ (2A/125°C); trr = 30ns; DO-214AC package | Slightly faster trr but higher VF at elevated temperature; identical mounting footprint | Select when prioritizing minimum reverse recovery charge over low-temperature VF. |
| SS26 (Good-Ark) | 2A/600V; VF = 1.75V max (2A/25°C); trr = 50ns; DO-214AC package; no J-STD-020 MSL rating published | Slower recovery increases switching loss in >200kHz designs; lacks documented moisture sensitivity classification | Acceptable for cost-sensitive industrial lighting where MSL Level 1 and sub-40ns trr are not required. |
Compared with STTH2R06U and SS26, ES2HA R3G offers tighter trr specification (≤35 ns), verified J-STD-020 Level 1 handling, and lower typical VF at room temperature - making it preferred for high-reliability, high-frequency DC-DC and snubber use cases requiring consistent parametric stability.

FAQ
What is the maximum junction temperature rating for ES2HA R3G?
The ES2HA R3G has a maximum junction temperature (TJ) rating of +150°C, with an operational range spanning –55°C to +150°C. This rating enables reliable deployment in thermally demanding environments such as enclosed LED drivers and industrial power supplies. Derating curves in the official TSC datasheet define allowable average forward current versus lead temperature, ensuring safe operation within this thermal envelope. The ES2HA R3G must be mounted on adequate copper area to maintain TJ ≤ 150°C under full load.
Does ES2HA R3G support lead-free reflow soldering?
Yes, ES2HA R3G supports lead-free reflow soldering per J-STD-002 requirements. Its matte tin-plated leads are fully compatible with Pb-free SAC305 alloy profiles, including peak temperatures up to 260°C for ≤10 seconds. The DO-214AC (SMA) package's UL 94V-0 molding compound withstands multiple reflow cycles without delamination or cracking. The ES2HA R3G is also classified as J-STD-020 Level 1, meaning it requires no floor-life baking prior to assembly.
What is the reverse recovery time test condition for ES2HA R3G?
The reverse recovery time (trr) for ES2HA R3G is measured under the condition: forward current IF = 0.5A, reverse current IR = 1.0A, and reverse recovery current Irr = 0.25A, per the TSC datasheet. This standardized test reflects real-world behavior in hard-switched topologies. The specified maximum value is 35 ns, confirming its suitability for high-frequency applications like 200 kHz+ flyback and LLC converters. The ES2HA R3G's trr remains stable across temperature due to its glass-passivated junction.
Is ES2HA R3G pin-compatible with other devices in the ES2xx series?
Yes, all ES2xx devices - including ES2AA through ES2JA - share identical DO-214AC (SMA) package dimensions, pinout, and mechanical footprint. The ES2HA R3G uses the same anode/cathode terminal arrangement and cathode band polarity marking as ES2FA, ES2GA, and ES2JA. This allows direct substitution based on required VRRM without PCB layout changes, provided thermal and electrical design margins accommodate differences in VF and leakage.
What does the 'R3G' suffix indicate in ES2HA R3G?
The 'R3G' suffix in ES2HA R3G denotes tape-and-reel packaging: R3 = 7,500 units per reel, G = green compound (halogen-free molding material per IEC 61249-2-21). This matches the ordering code structure defined in the TSC datasheet. The ES2HA R3G is not a functional variant - electrical and thermal specifications are identical to ES2HA in alternate packaging formats. The 'R3G' designation confirms compliance with environmental and logistics requirements for high-volume SMT production.
