Product details
Overview
ES1DLH from Taiwan Semiconductor is a 1A, 200V super fast surface-mount rectifier diode in Sub SMA package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A, and AEC-Q101 qualification for automotive use in DC-DC converters and freewheeling circuits.
For engineers reviewing the ES1DLH datasheet, ES1DLH pinout, ES1DLH application, or ES1DLH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward surge current rating (30 A), junction-to-lead thermal resistance (35 °C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The ES1DLH employs a glass-passivated single-die silicon junction optimized for high-speed switching in low-loss power conversion. Its 35 ns trr and 0.95 V VF at 1 A enable efficient operation in 100–500 kHz DC-DC topologies where reverse recovery losses must be minimized.
Designed for automotive-grade reliability, the ES1DLH meets AEC-Q101 stress test requirements and operates across –55°C to +150°C junction temperature range. Its Sub SMA package supports automated placement and provides 85 °C/W junction-to-ambient thermal resistance under standard PCB conditions.
Key Specifications

| IF | 1 A - continuous average forward current rating at TA = 75°C on FR-4 PCB |
| IFSM | 30 A - non-repetitive peak surge current handling capability (8.3 ms half-sine) |
| trr | 35 ns - reverse recovery time enabling high-frequency switching with low switching loss |
| VF @ 1 A | 0.95 V - forward voltage drop determining conduction loss in power path |
| CJ @ 4 V | 10 pF - junction capacitance affecting high-frequency noise and EMI behavior |
| RθJL | 35 °C/W - thermal resistance from junction to lead, critical for solder-joint reliability |

Applications
| Automotive DC-DC Converters | LED Driver Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in 12 V → 5 V/3.3 V buck converters for ADAS ECUs and infotainment modules. IC Role / Device Role / Timing Role: Fast-recovery output rectifier replacing Schottky diodes where higher VRRM and thermal stability are required. Use Value: 35 ns trr minimizes switching loss at 250 kHz; 200 V rating accommodates transient spikes in 12 V systems. | Use Scenario: Freewheeling path in constant-current LED drivers for automotive exterior lighting (DRL, turn signals). IC Role / Device Role / Timing Role: Clamp diode across inductive LED driver switch to absorb back-EMF during turn-off. Use Value: 30 A IFSM withstands high-energy inductive kickback; AEC-Q101 ensures lifetime reliability under vibration/thermal cycling. |
| Snubber Networks | Industrial Power Supplies |
Use Scenario: RC snubber across MOSFETs or IGBTs in motor drive inverters operating up to 20 kHz. IC Role / Device Role / Timing Role: Fast-recovery diode in series with snubber capacitor to control dV/dt and suppress ringing. Use Value: Low CJ (10 pF) reduces capacitive loading on switching node; 0.95 V VF limits snubber conduction loss. | Use Scenario: Output rectification in industrial AC-DC adapters rated for 230 VAC input and 24 V/1 A output. IC Role / Device Role / Timing Role: Primary rectifier in flyback or forward converter secondary stage. Use Value: 150°C TJ max and 35 °C/W RθJL support sustained 1 A operation without derating on compact heatsinks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02UF | VRRM = 200 V, trr = 30 ns, VF = 0.92 V @ 1 A, same Sub SMA package | Slightly faster recovery but lower IFSM (25 A vs. 30 A); no AEC-Q101 documentation | Preferred where ultra-low trr dominates over surge margin and automotive qualification is not required |
| ON Semi MUR120 | VRRM = 200 V, trr = 35 ns, VF = 0.98 V @ 1 A, DO-41 through-hole package | Through-hole mounting only; higher RθJA (~100 °C/W); no AEC-Q101 or MSL Level 1 | Acceptable for prototyping or non-automotive industrial use where board space and reflow are not constraints |
Compared with STTH1R02UF and MUR120, the ES1DLH uniquely combines AEC-Q101 qualification, J-STD-020 Level 1 handling, and 30 A surge rating in a low-profile Sub SMA package-making it the only option qualified for volume automotive production with zero bake requirement and validated thermal performance.

FAQ
What is the maximum junction temperature rating for ES1DLH?
The ES1DLH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 thermal stress testing. This allows continuous 1 A operation in automotive under-hood environments when mounted on standard FR-4 PCB with adequate copper area. Derating begins above 75°C ambient, per the forward current derating curve in the ES1DLH datasheet.
Is ES1DLH pin-compatible with other parts in the ES1xLH series?
Yes, all ES1xLH parts-including ES1ALH, ES1BLH, ES1CLH, ES1DLH, ES1FLH, ES1GLH, ES1HLH, and ES1JLH-share identical Sub SMA package dimensions, pinout, and mechanical footprint. Only VRRM, VF, and CJ vary across the series; the ES1DLH uses marking code "EDL" and is electrically distinct but mechanically interchangeable.
Does ES1DLH require baking before reflow soldering?
No, the ES1DLH is rated J-STD-020 Moisture Sensitivity Level 1, meaning it has unlimited floor life and does not require baking prior to reflow. This eliminates process overhead in high-volume SMT lines and supports just-in-time manufacturing without moisture-related popcorning risk.
What is the reverse recovery time (trr) specification for ES1DLH?
The ES1DLH 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 of the official ES1DLH datasheet and enables efficient operation in switching power supplies operating up to 500 kHz.
How does ES1DLH differ from standard fast recovery diodes like FR107?
The ES1DLH delivers significantly faster recovery (35 ns vs. ~500 ns for FR107), lower forward voltage (0.95 V vs. ~1.3 V), and AEC-Q101 qualification-making it suitable for high-frequency automotive power conversion where FR107 would incur excessive switching loss and lack automotive reliability validation. The ES1DLH also uses Sub SMA instead of DO-41 packaging.
