Product details
Overview
ES1DH from Taiwan Semiconductor is a 1A, 200V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 1A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES1DH datasheet, ES1DH pinout, ES1DH application, or ES1DH equivalent, key selection criteria include repetitive peak reverse voltage (200V), junction-to-lead thermal resistance (35°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for high-reliability automotive power conversion.
Technical Context
The ES1DH belongs to Taiwan Semiconductor's ES1xH super fast rectifier family with single-die construction and glass-passivated junction. It delivers low forward voltage drop and ultra-fast switching (trr ≤ 35ns) to minimize switching losses in high-frequency DC-DC converters and automotive lighting drivers.
Its DO-214AC (SMA) package supports automated placement and meets UL 94V-0 flammability rating, while the cathode-band polarity marking and matte tin-plated leads ensure reliable solderability per J-STD-002 and JESD 201 Class 2 whisker resistance.

Applications
| Automotive LED Lighting Driver | DC-DC Buck Converter Output Rectification |
|---|---|
Use Scenario: High-brightness LED headlamp module with PWM dimming and thermal foldback protection. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck controller output stage, conducting during low-side switch off-time. Use Value: 35ns trr minimizes reverse recovery charge (Qrr), reducing voltage spikes and MOSFET stress during transition-critical for 200kHz+ switching in space-constrained lamp housings. | Use Scenario: 12V-to-5V/3.3V point-of-load converter in infotainment head unit power supply. IC Role / Device Role / Timing Role: Output rectifier in non-synchronous buck topology, handling continuous 1A load with minimal conduction loss. Use Value: 0.95V VF at 1A lowers average power dissipation to <1W, enabling use without heatsink on 1oz copper layers-reducing BOM cost and board area. |
| Automotive Snubber Network | Engine Control Unit (ECU) Inductive Load Clamp |
Use Scenario: RCD snubber across primary-side MOSFET in isolated flyback auxiliary supply for body control module. IC Role / Device Role / Timing Role: Fast recovery diode clamping transient energy during MOSFET turn-off, absorbing voltage overshoot. Use Value: 200V VRRM and 30A IFSM withstand repeated 400V spikes; 35ns trr ensures rapid turn-on before voltage peaks, limiting ring amplitude and EMI. | Use Scenario: Solenoid driver circuit controlling fuel injector or idle air control valve in gasoline engine ECU. IC Role / Device Role / Timing Role: Freewheeling diode across inductive coil, providing current recirculation path when driver FET turns off. Use Value: AEC-Q101 qualification guarantees operation over full automotive temperature range (-40°C to +125°C ambient); glass passivation prevents corrosion-induced failure in humid under-hood conditions. |
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-1EWH02-M3/5AT | Same DO-214AC package, 200V VRRM, but VF = 0.93V (typ) and trr = 25ns (typ); slightly lower leakage (IR = 3µA max) | Better suited for ultra-high-efficiency 500kHz+ converters where Qrr reduction is prioritized over cost | Prefer VS-1EWH02-M3/5AT if layout allows tighter thermal margin and design targets <10mW conduction loss reduction |
| ON Semiconductor ES1DHE3/5BT | Identical electrical specs (200V/1A/35ns/0.95V), same AEC-Q101 grade, but uses different molding compound and date-code marking format | No functional difference; validated for identical automotive applications including lighting and ECU clamping | ES1DHE3/5BT is a direct second-source option with identical performance and qualification-ideal for dual-sourcing risk mitigation |
Compared with VS-1EWH02-M3/5AT and ES1DHE3/5BT, the ES1DH offers optimal balance of cost, AEC-Q101 assurance, and proven field reliability in DO-214AC footprint-making it preferred for volume automotive production where qualification continuity and supply chain stability are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for ES1DH?
The ES1DH has a VRRM rating of 200 V, meaning it can reliably block up to 200 volts of reverse voltage in repetitive applications such as DC-DC converter freewheeling paths or snubber networks. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor ES1AH–ES1JH datasheet Version B2112, and applies exclusively to the ES1DH variant within the family.
Is ES1DH qualified for automotive applications?
Yes, ES1DH is AEC-Q101 qualified per the manufacturer's documentation, confirming its suitability for automotive use cases including engine control units, LED lighting drivers, and body electronics. The qualification covers temperature cycling, mechanical shock, and humidity testing-ensuring reliability under real-world vehicle operating conditions from -40°C to +125°C ambient.
What is the forward voltage drop (VF) of ES1DH at rated current?
The ES1DH exhibits a maximum forward voltage drop of 0.95 V at 1 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This VF value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss and thermal performance in high-duty-cycle applications like automotive power supplies.
Does ES1DH have a defined reverse recovery time (trr)?
Yes, ES1DH has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultra-fast recovery characteristic enables high-frequency switching in DC-DC converters and reduces switching losses and EMI generation compared to standard fast recovery diodes.
What package type does ES1DH use, and is it compatible with automated assembly?
ES1DH uses the DO-214AC (SMA) surface-mount package, which is explicitly noted as ideal for automated placement in the manufacturer's features list. Its matte tin-plated leads comply with J-STD-002 solderability standards, and its J-STD-020 Level 1 moisture sensitivity rating allows indefinite floor life-eliminating pre-bake steps in SMT production lines.
