Product details
Overview
ES2GA-T from Taiwan Semiconductor is a 2A, 400V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 1.09V max forward voltage at 2A/25°C, 35ns reverse recovery time, and 19pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the ES2GA-T datasheet, ES2GA-T pinout, ES2GA-T application, or ES2GA-T equivalent, key selection criteria include its 400V VRRM, thermal resistance of 14°C/W (junction-to-lead), low leakage (<5µA at 25°C), and compatibility with automated SMT placement per J-STD-020 Level 1 moisture sensitivity.
Technical Context
The ES2GA-T employs a glass-passivated silicon die optimized for high-speed switching, delivering fast reverse recovery (trr ≤ 35ns) with controlled soft recovery characteristics to minimize EMI in DC-DC converters. Its single-die configuration supports unidirectional conduction with cathode-band polarity marking.
Thermal performance is characterized with RθJL = 14°C/W on a 5mm × 5mm copper pad, enabling reliable operation up to TJ = 150°C. The device meets RoHS and halogen-free requirements per IEC 61249-2-21, with matte tin-plated leads solderable per J-STD-002.

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 | 400V VRRM, 2A IF, trr = 30ns, VF = 1.15V @ 2A, DO-214AC | Slightly higher VF increases conduction loss; tighter trr tolerance aids ultra-high-frequency designs | Prefer when <30ns trr is required and 0.06V higher VF is acceptable |
| MBR240 | 40V VRRM, 2A IF, Schottky, VF = 0.52V @ 2A, DO-214AC | Lower VF but insufficient VRRM for 400V bus applications; unsuitable for AC-DC primary-side or 400V DC links | Select only for low-voltage (<60V) DC-DC where ultra-low VF outweighs voltage rating needs |
Compared with STTH2R04 and MBR240, the ES2GA-T provides optimal balance of 400V rating, 35ns recovery, and 1.09V VF in a standard SMA package-making it suitable for cost-sensitive, thermally constrained 400V switching power stages where Schottky limitations or tighter trr tolerances are not critical.

FAQ
What is the maximum junction temperature rating for ES2GA-T?
The ES2GA-T has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version D2111. This rating allows continuous operation in thermally demanding environments such as enclosed LED drivers or industrial power modules, provided thermal design respects RθJL = 14°C/W and PCB copper area guidelines. Derating curves confirm usable current down to –55°C ambient.
Does ES2GA-T support automated SMT placement without pre-baking?
Yes, ES2GA-T is rated J-STD-020 Level 1 for moisture sensitivity, meaning it can be placed directly onto PCBs using standard reflow profiles without prior baking. This eliminates process steps and reduces risk of moisture-induced popcorning during soldering-critical for high-throughput manufacturing lines producing power adapters or industrial controls where ES2GA-T is commonly deployed.
How does the forward voltage of ES2GA-T compare across temperature?
At 2A, ES2GA-T's forward voltage drops from 1.09V at 25°C to 0.92V at 125°C (max), reflecting negative temperature coefficient behavior typical of silicon PN junctions. This reduction lowers conduction loss at elevated temperatures, aiding thermal stability in sealed enclosures. Data is confirmed in the Electrical Specifications table of the Taiwan Semiconductor ES2DA-T–ES2JA-T datasheet (Version D2111).
What is the reverse recovery time specification for ES2GA-T?
The ES2GA-T has a maximum reverse recovery time (trr) of 35ns, measured under conditions IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is specified in the Electrical Specifications section of the official Taiwan Semiconductor datasheet and enables reliable operation in switching power supplies operating up to 300 kHz without excessive switching loss or voltage overshoot.
Is ES2GA-T RoHS and halogen-free compliant?
Yes, ES2GA-T is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor ES2DA-T–ES2JA-T datasheet (Version D2111). The molding compound meets UL 94V-0 flammability standards, and terminals use matte tin plating qualified per J-STD-002-ensuring environmental compliance and solderability in regulated markets.
