Product details
Overview
ES2GFL from Taiwan Semiconductor is a 2 A, 400 V super fast surface-mount rectifier in SOD-123FL package, featuring 1.09 V forward voltage at 2 A / 25°C, 35 ns reverse recovery time, and 15 pF junction capacitance - optimized for high-frequency switching in DC/DC converters and freewheeling paths.
For engineers reviewing the ES2GFL datasheet, ES2GFL pinout, ES2GFL application, or ES2GFL equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, low leakage (≤5 µA @ 25°C), thermal resistance (RθJA = 116 °C/W), and compatibility with automated SMT assembly on standard PCB pads.
Technical Context
The ES2GFL employs a glass-passivated silicon junction to achieve fast recovery (trr ≤ 35 ns) and stable operation up to 150 °C junction temperature. Its single-die configuration and SOD-123FL package support high-density board layouts while maintaining robust surge capability (IFSM = 40 A at 8.3 ms).
Designed for high-efficiency power conversion, it delivers low forward voltage (VF = 1.09 V typ. @ 2 A, 25°C) and minimal capacitive loading (CJ = 15 pF @ 1 MHz, 4 V), reducing switching losses in SMPS and inverters operating above 50 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MURS240T3G | Same 400 V VRRM, 2 A IF, but 25 ns trr; VF = 1.25 V @ 2 A, 25°C | Marginally faster recovery but higher forward drop increases conduction loss | Prefer when ultra-low trr dominates over VF in >300 kHz designs |
| Vishay VS-ES2G-M3/5BT | Identical VRRM, IF, trr, and VF specs; same SOD-123FL package and marking | No functional deviation - direct second-source option with identical thermal and electrical behavior | Recommended for supply chain diversification without design revalidation |
Compared with MURS240T3G and VS-ES2G-M3/5BT, the ES2GFL offers the lowest forward voltage among 400 V super fast rectifiers in SOD-123FL, making it optimal for thermally constrained, medium-frequency power stages where conduction loss is dominant.

FAQ
What is the maximum junction temperature rating for the ES2GFL?
The ES2GFL has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version B2103. This rating applies under continuous operation with proper PCB thermal management - specifically using a 5 mm × 5 mm copper pad - and enables reliable use in industrial ambient environments up to +85°C. The ES2GFL maintains specified electrical performance within this thermal envelope.
Does the ES2GFL have a cathode band marking, and how is polarity identified?
Yes, the ES2GFL uses a visible cathode band on the SOD-123FL package body to indicate polarity, consistent with JEDEC-standard diode marking conventions. The banded end corresponds to the cathode terminal, which must be connected toward the higher-potential node in forward-biased operation. This marking is confirmed in the "MECHANICAL DATA" and "MARKING DIAGRAM" sections of the ES2DFL–ES2JFL datasheet (Version B2103), and is essential for correct orientation during automated placement and manual inspection of the ES2GFL.
What is the reverse recovery time (trr) of the ES2GFL, and under what test conditions is it measured?
The ES2GFL has a reverse recovery time (trr) of ≤35 ns, measured under the condition: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the "ELECTRICAL SPECIFICATIONS" table of the Taiwan Semiconductor datasheet (Version B2103). This value reflects the device's super fast switching capability and is critical for minimizing switching losses in high-frequency power converters. The ES2GFL's trr remains stable across its rated temperature range.
Is the ES2GFL suitable for use in automotive applications?
The ES2GFL is not qualified to AEC-Q101 or automotive-grade reliability standards, and Taiwan Semiconductor explicitly states in the datasheet notice that these products "are not designed for use in medical, life-saving, or life-sustaining applications." While its –55°C to +150°C operating range overlaps with some automotive ambient requirements, the ES2GFL lacks automotive-specific qualification, stress testing, and PPAP documentation. For automotive systems, a formally AEC-Q101-qualified alternative should be selected instead of the ES2GFL.
What is the junction-to-ambient thermal resistance (RθJA) of the ES2GFL, and how is it measured?
The ES2GFL has a junction-to-ambient thermal resistance (RθJA) of 116 °C/W, measured on a standard test board with a 5 mm × 5 mm copper pad per the "THERMAL PERFORMANCE" section of the Taiwan Semiconductor datasheet (Version B2103). This value assumes natural convection cooling and defines the worst-case thermal gradient from die to ambient air under standardized PCB layout conditions. Real-world RθJA for the ES2GFL will improve with larger copper areas, internal planes, or forced airflow.
