Product details
Overview
ES2FH from Taiwan Semiconductor is a 2A, 400V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES2FH datasheet, ES2FH pinout, ES2FH application, or ES2FH equivalent, key selection criteria include peak reverse voltage (400V), surge current rating (50A), junction-to-lead thermal resistance (20°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The ES2FH employs a glass passivated silicon die in a single-die configuration, optimized for high-frequency switching in DC-DC converters and automotive lighting. Its 35ns trr and low CJ (20pF at 1MHz/4V) minimize switching losses and EMI generation during rapid polarity transitions.
Thermally, the device supports continuous operation up to TJ = 150°C with RθJL = 20°C/W and RθJA = 75°C/W, enabling reliable performance in compact, convection-cooled layouts without forced airflow.

Applications
| Automotive LED Lighting | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: High-brightness LED headlamp modules requiring efficient, compact, and AEC-Q101-compliant rectification in buck-derived constant-current drivers. IC Role / Device Role / Timing Role: Freewheeling diode providing current path during MOSFET off-time and clamping inductive kickback. Use Value: 35ns trr minimizes switching loss and audible noise; 400V VRRM accommodates load-dump transients up to ISO 7637-2 Pulse 5a. | Use Scenario: Secondary-side rectification in isolated 12V–48V industrial DC-DC converters operating at 200–500 kHz. IC Role / Device Role / Timing Role: Uncontrolled rectifier converting transformer secondary AC to regulated DC output. Use Value: Low VF (1.30V) reduces conduction loss; 20pF CJ limits high-frequency ringing and EMI filter burden. |
| Snubber Network Diode | Freewheeling in Automotive Solenoid Drivers |
Use Scenario: RCD snubber across MOSFETs or IGBTs in motor control inverters handling 42V battery systems. IC Role / Device Role / Timing Role: Fast recovery diode directing transient energy into RC network during switching transitions. Use Value: 35ns trr ensures clean turn-off and prevents snubber inefficiency due to slow recovery tail current. | Use Scenario: Inductive load flyback protection in 12V automotive solenoid valve drivers (e.g., transmission shift actuators). IC Role / Device Role / Timing Role: Freewheeling path for coil current decay when driver FET turns off. Use Value: 50A IFSM withstands repeated inductive surges; AEC-Q101 qualification ensures robustness over vehicle lifetime. |
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-ES2FH-M3/5BT | Identical VRRM (400V), IF (2A), trr (35ns); same DO-214AA package; minor VF variation (1.25V typ vs 1.30V max) | Same automotive and industrial DC-DC use cases; validated in Vishay's AEC-Q101 test report | Select for dual-source supply chain resilience where identical electrical specs and footprint are required |
| ON Semiconductor MUR240RLG | Higher VRRM (400V same), but slower trr (60ns); VF = 1.25V typ; same SMB package and IF rating | Suitable for lower-frequency (<100 kHz) converters where reduced recovery speed is acceptable | Choose when cost sensitivity outweighs high-frequency efficiency needs; verify snubber design impact from longer trr |
Compared with VS-ES2FH-M3/5BT, the ES2FH offers tighter VF max specification and direct Taiwan Semiconductor AEC-Q101 documentation; versus MUR240RLG, ES2FH delivers 42% faster recovery for improved high-frequency efficiency and reduced EMI, at marginally higher VF.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES2FH?
The ES2FH has a VRRM of 400 V, meaning it can reliably block up to 400 volts of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor ES2AH–ES2JH datasheet (Version A2102). The ES2FH is part of a series where the letter 'F' explicitly denotes the 400V variant.
Is ES2FH qualified for automotive applications?
Yes, ES2FH is AEC-Q101 qualified, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing, making ES2FH suitable for under-hood and lighting applications in passenger vehicles and commercial vehicles.
What is the forward voltage drop of ES2FH at rated current?
The ES2FH has a maximum forward voltage (VF) of 1.30 V at IF = 2 A and TJ = 25°C, per the Electrical Specifications table. This value represents the worst-case conduction loss under nominal conditions and is used for thermal and efficiency calculations in power supply designs using the ES2FH.
What package type does ES2FH use, and what are its key mechanical attributes?
ES2FH uses the DO-214AA (SMB) surface-mount package. Key attributes include a low-profile molded case meeting UL 94V-0 flammability, matte tin-plated leads compliant with J-STD-002 solderability, JESD201 Class 2 whisker resistance, and polarity indicated by a visible cathode band. Its weight is approximately 0.090 g.
What is the reverse recovery time (trr) of ES2FH, and why does it matter?
The ES2FH has a reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery minimizes switching losses and prevents cross-conduction in bridge or synchronous rectifier topologies, directly improving efficiency and reducing EMI in high-frequency DC-DC converters where ES2FH is deployed.
