Product details
Overview
ES1JFSH from Taiwan Semiconductor is a 600 V, 1 A super fast surface-mount rectifier in SOD-128 package, featuring 35 ns reverse recovery time, 1.15 V forward voltage at 1.0 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 ES1JFSH datasheet, ES1JFSH pinout, ES1JFSH application, or ES1JFSH equivalent, key selection criteria include peak reverse voltage (600 V), junction-to-lead thermal resistance (28 °C/W), reverse recovery time (≤35 ns), and AEC-Q101 qualification for automotive power systems.
Technical Context
This discrete silicon rectifier uses a glass-passivated PN junction optimized for fast switching with minimal stored charge. Its 35 ns trr and low CJ (15 pF at 1 MHz, 4 V) enable operation in 100–500 kHz DC/DC topologies without excessive switching loss or EMI generation.
The SOD-128 package provides enhanced thermal performance over standard SOD-123: RθJL = 28 °C/W and RθJC = 20 °C/W on a 5 mm × 5 mm Cu pad, supporting continuous 1 A conduction at TJ ≤ 150 °C in compact automotive and industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage; defines safe blocking capability in high-voltage DC bus or flyback clamp circuits |
| IF | 1 A - average forward current rating; supports continuous conduction in 12–48 V output DC/DC stages |
| trr | ≤35 ns - reverse recovery time; enables efficient operation above 200 kHz with reduced switching loss and ringing |
| VF @ 1A/25°C | 1.15 V - forward voltage drop; determines conduction loss (1.15 W at 1 A) and thermal load in freewheeling path |
| RθJL | 28 °C/W - junction-to-lead thermal resistance; allows direct thermal coupling to PCB copper for passive cooling without heatsink |
| CJ @ 1MHz/4V | 15 pF - junction capacitance; limits displacement current and EMI in high-dv/dt snubber applications |
Pinout & Package

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-1EWH06-M3/5AT | Same SOD-128 package, 600 V VRRM, but trr = 50 ns (vs. 35 ns), VF = 1.25 V @ 1 A/25°C | Higher conduction and switching loss; less suitable for >250 kHz designs | Acceptable where cost sensitivity outweighs efficiency targets and layout allows minor thermal margin |
| ON Semiconductor MUR160RLG | SOD-123 package (smaller footprint), 600 V VRRM, trr = 35 ns, but RθJA = 100 °C/W (vs. 67 °C/W) and no AEC-Q101 qualification | Limited thermal capability and non-automotive qualified; unsuitable for underhood deployment | Only for non-automotive, low-power, or space-constrained applications where qualification is not required |
Compared with VS-1EWH06-M3/5AT and MUR160RLG, ES1JFSH delivers superior high-frequency efficiency via lower trr and VF, better thermal dissipation in SOD-128, and automotive-grade reliability-making it the preferred choice for demanding 48 V automotive and industrial DC/DC systems.

FAQ
What is the maximum junction temperature rating for ES1JFSH?
The ES1JFSH has a maximum junction temperature (TJ MAX) of +150 °C, verified per absolute maximum ratings in the official datasheet. This rating enables operation in underhood automotive environments and enclosed industrial power modules. Derating curves confirm sustained 1 A forward current is supported up to this limit when mounted on a 5 mm × 5 mm Cu pad. The ES1JFSH must not exceed this temperature during steady-state or transient conditions to maintain reliability and AEC-Q101 compliance.
Is ES1JFSH pin-compatible with other parts in the ES1xFSH family?
Yes, all ES1xFSH variants-including ES1BFSH, ES1DFSH, ES1GFSH, and ES1JFSH-share identical SOD-128 package dimensions, pinout, and mechanical footprint. The only differences are VRRM (100–600 V), VF, and trr values. This allows design reuse across voltage grades without PCB layout changes, provided the selected variant meets the circuit's blocking and loss requirements. The ES1JFSH retains the same anode/cathode terminal assignment and polarity marking as the family.
Does ES1JFSH meet automotive qualification standards?
Yes, ES1JFSH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (UHAST), confirming suitability for automotive power electronics. The ES1JFSH is intended for underhood and cabin applications where reliability under thermal, humidity, and vibration stress is mandatory-not just for industrial use.
What is the reverse recovery time (trr) specification for ES1JFSH?
The ES1JFSH has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table and supports high-frequency switching up to 500 kHz with minimal switching loss and EMI. Unlike slower rectifiers, the ES1JFSH's 35 ns trr enables clean turn-off in buck, flyback, and snubber circuits-critical for maintaining efficiency in modern DC/DC converters.
What is the forward voltage drop of ES1JFSH at operating conditions?
The ES1JFSH exhibits a typical forward voltage (VF) of 1.15 V at 1.0 A and 25 °C, rising to 0.93 V at 1.0 A and 125 °C. At 0.5 A and 25 °C, VF is 1.04 V. These values are measured under pulsed conditions (PW = 0.3 ms) and define conduction loss behavior across the operating temperature range. The ES1JFSH's VF directly impacts thermal design, especially in high-duty-cycle freewheeling paths where power dissipation equals IF × VF.
