Product details
Overview
ES2JFSH from Taiwan Semiconductor is a 2 A, 600 V super fast surface-mount rectifier in SOD-128 package, featuring 35 ns reverse recovery time, 1.24 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-frequency DC/DC converters where low switching loss and thermal robustness are critical.
For engineers reviewing the ES2JFSH datasheet, ES2JFSH pinout, ES2JFSH application, or ES2JFSH equivalent, key selection criteria include its 600 V VRRM, 50 A IFSM surge rating, 24 °C/W RθJL, J-STD-020 Level 1 moisture sensitivity, and cathode-band polarity marking-essential for automotive power supply and industrial converter designs.
Technical Context
The ES2JFSH employs a glass-passivated silicon junction optimized for super-fast recovery (trr ≤ 35 ns), enabling efficient operation in high-frequency switching topologies. Its single-die configuration and SOD-128 low-profile package support automated placement while maintaining thermal performance with RθJL = 24 °C/W on a 5 mm × 5 mm Cu pad.
Electrical behavior is characterized by voltage-dependent forward voltage: 1.24 V at 2 A/25°C rising to 1.14 V max at 2 A/125°C, and leakage current limited to 1 µA at 25°C and 25 µA at 125°C under rated reverse voltage. Junction capacitance is 21 pF at 1 MHz/4 V.
Key Specifications

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-ES2JHM3 | Same SOD-128 package, 600 V VRRM, but trr = 50 ns (max); VF = 1.3 V @ 2 A/25°C | Higher recovery time increases switching loss above 200 kHz; suitable for lower-frequency industrial SMPS | Select when cost sensitivity outweighs high-frequency efficiency needs |
| ON Semiconductor MUR260 | TO-220AC package, 600 V VRRM, trr = 35 ns, but larger footprint and higher RθJA (50 °C/W) | Requires heatsinking for >1 A continuous; not suitable for space-constrained automotive modules | Select only when through-hole assembly or legacy board compatibility is mandatory |
Compared with VS-ES2JHM3 and MUR260, the ES2JFSH delivers superior high-frequency efficiency via tighter trr control and lower thermal resistance in a compact, AEC-Q101-qualified SMD package-making it optimal for next-gen automotive and dense industrial power supplies.

FAQ
What is the maximum junction temperature rating for ES2JFSH?
The ES2JFSH has a maximum junction temperature (TJ) of +150°C, verified across its full operating range from –55°C to +150°C. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves confirm 2 A continuous current is maintainable up to 125°C ambient when mounted on a 5 mm × 5 mm Cu pad. The ES2JFSH must not exceed this limit to ensure long-term parametric stability and AEC-Q101 compliance.
Is ES2JFSH compatible with lead-free reflow soldering processes?
Yes, the ES2JFSH is fully compatible with lead-free reflow soldering per J-STD-020 Level 1 moisture sensitivity-no pre-baking is required. Its matte tin-plated leads meet J-STD-002 solderability standards, and the UL 94V-0 molding compound withstands peak reflow temperatures up to 260°C. The ES2JFSH's thermal performance (RθJL = 24 °C/W) also helps mitigate thermal stress during repeated reflow cycles.
How does the forward voltage of ES2JFSH vary with temperature?
The ES2JFSH exhibits negative temperature coefficient behavior: VF decreases as junction temperature rises-1.24 V at 2 A/25°C drops to 1.01 V typical at 2 A/125°C. This improves thermal stability in high-power-density designs. The ES2JFSH datasheet specifies max VF = 1.70 V at 2 A/25°C and 1.14 V at 2 A/125°C, ensuring predictable conduction loss across its full operating range.
Does ES2JFSH have automotive qualification?
Yes, the ES2JFSH is explicitly AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor datasheet revision B2103. This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock-validating suitability for automotive powertrain, chassis, and body electronics. The ES2JFSH's glass-passivated junction and J-STD-020 Level 1 rating further reinforce its automotive readiness.
What is the reverse recovery time specification for ES2JFSH?
The ES2JFSH has a maximum reverse recovery time (trr) of 35 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A. This value is guaranteed across temperature and process variation, enabling efficient operation in high-frequency DC/DC converters up to 500 kHz. The ES2JFSH's trr is tighter than many competing 600 V rectifiers, reducing switching losses and EMI generation.
