Product details
Overview
ES2GAL from Taiwan Semiconductor is a 2 A, 400 V super fast surface-mount rectifier diode in a Thin SMA package, featuring 35 ns reverse recovery time, 0.97 V forward voltage at 2 A/25°C, and 27 pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the ES2GAL datasheet, ES2GAL pinout, ES2GAL application, or ES2GAL equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, low-profile Thin SMA footprint, thermal resistance (RθJL = 24 °C/W), and suitability for DC-DC converters requiring fast recovery and low conduction loss.
Technical Context
The ES2GAL employs a glass-passivated silicon junction optimized for super-fast recovery (trr ≤ 35 ns) and low forward voltage drop across temperature. Its single-die configuration and Thin SMA package support automated SMT assembly with J-STD-020 Level 1 moisture sensitivity.
Thermal performance is characterized with RθJL = 24 °C/W and RθJA = 72 °C/W on a 5 mm × 5 mm Cu pad PCB, enabling reliable operation up to TJ = 150 °C under continuous 2 A forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| DC-DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated flyback or forward converters operating at 100–300 kHz. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency AC from transformer secondary into regulated DC output. Use Value: 0.97 V VF minimizes conduction loss; 35 ns trr prevents reverse recovery shoot-through in multi-phase designs. | Use Scenario: Freewheeling path in H-bridge motor drive inverters for HVAC or industrial pumps. IC Role / Device Role / Timing Role: Clamp inductive kickback during PWM dead-time, preventing voltage spikes on power switches. Use Value: 400 V VRRM safely handles bus voltages up to 340 V DC; 50 A IFSM absorbs short-circuit energy. |
| AC-DC Adapters | LED Drivers |
Use Scenario: Output rectification in compact 12–24 V, 20–60 W offline adapters with universal input. IC Role / Device Role / Timing Role: Final-stage unidirectional current path after transformer isolation and filtering. Use Value: Thin SMA footprint saves board space; 27 pF CJ limits high-frequency ringing and EMI generation. | Use Scenario: Constant-current regulation loop rectification in isolated LED drivers for street lighting. IC Role / Device Role / Timing Role: High-efficiency rectifier in secondary-side feedback circuitry powering optocoupler or shunt regulator. Use Value: 150 °C TJMAX ensures reliability under sealed, thermally limited luminaire enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | 400 V VRRM, 2 A IF, 30 ns trr, DO-214AC package (SMA), VF = 0.92 V @ 2 A | Slightly faster recovery but higher forward voltage tolerance variation; same thermal resistance profile | Preferred where tighter trr tolerance is required; verify lead finish compatibility with reflow profile |
| SB240 | 40 V VRRM, 2 A IF, 35 ns trr, DO-214AA package (SMB), VF = 0.52 V @ 2 A | Lower voltage rating limits use to low-voltage outputs (<30 V); SMB package has larger footprint and higher RθJA | Only suitable for sub-40 V secondary rails; not interchangeable in 400 V systems due to blocking voltage mismatch |
Compared with STTH2R04 and SB240, the ES2GAL offers optimal balance of 400 V blocking, 35 ns recovery, and Thin SMA form factor-making it ideal for space-constrained, medium-voltage SMPS where thermal management via lead conduction is prioritized.

FAQ
What is the maximum repetitive peak reverse voltage rating for ES2GAL?
The ES2GAL has a specified VRRM of 400 V, meaning it can reliably block up to 400 V of repetitive reverse voltage without breakdown. This rating is validated per JEDEC test conditions and defines the upper limit for safe operation in rectifier or freewheeling configurations. Exceeding this voltage risks avalanche failure or parametric shift. The ES2GAL datasheet confirms this value in the Absolute Maximum Ratings table under the ES2GAL column.
What is the forward voltage drop of ES2GAL at 2 A and 25°C?
The ES2GAL exhibits a typical forward voltage (VF) of 0.97 V at 2 A and 25°C, with a maximum of 1.30 V under the same conditions. This value is measured per pulse test (PW = 0.3 ms) and directly impacts conduction loss and thermal design. At 125°C, VF drops to 0.81 V (typ) / 0.91 V (max), reflecting the negative temperature coefficient of silicon diodes. These values are specified in the Electrical Specifications table for ES2GAL.
Does ES2GAL have a defined reverse recovery time, and what is its value?
Yes, the ES2GAL has a specified reverse recovery time (trr) of ≤35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency applications such as DC-DC converters operating above 100 kHz. The trr value is confirmed in the Electrical Specifications section of the ES2GAL datasheet and distinguishes it as a "super fast" rectifier versus standard or fast recovery types.
What package type does ES2GAL use, and what are its key mechanical features?
The ES2GAL uses the Thin SMA package-a surface-mount variant of the DO-214AC outline with reduced height (max 2.2 mm). Key features include glass-passivated chip junction, matte tin-plated leads compliant with J-STD-002, J-STD-020 Level 1 moisture sensitivity, UL 94V-0 flammability rating, and cathode polarity indicated by a band. Its 0.029 g weight and 5 mm × 5 mm Cu pad thermal test condition are documented in the Mechanical Data section of the ES2GAL datasheet.
Is ES2GAL suitable for use in automotive applications?
The ES2GAL is not qualified to AEC-Q101 or automotive-grade reliability standards, and Taiwan Semiconductor explicitly states that its ES2xAL series is not designed for medical, life-saving, or life-sustaining applications-including automotive safety-critical systems. While the device operates from −55°C to +150°C and meets RoHS/halogen-free requirements, it lacks automotive-specific qualification testing (e.g., HTOL, TC, ESD). For automotive use, consult TSC's AEC-Q101-certified rectifier portfolio or perform full application-level validation before deployment.
