Product details
Overview
ES1D-LS from Diodes Incorporated is a surface-mount super fast rectifier diode rated for 200 V repetitive peak reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current, with 0.92 V forward voltage at 1.0 A DC and 25 ns maximum reverse recovery time. It features glass passivation, AEC-Q101 qualification, and RoHS-compliant lead-free packaging for automotive and industrial power conversion.
For engineers reviewing the ES1D-LS datasheet, ES1D-LS pinout, ES1D-LS application, or ES1D-LS equivalent, this device serves as a high-efficiency, low-leakage rectifier in compact DC/DC converters, auxiliary power supplies, and LED driver input stages where fast switching, thermal robustness, and automotive-grade reliability are required.
Technical Context
This super fast rectifier uses a planar epitaxial silicon junction structure optimized for minimal reverse recovery charge (Qrr) and low forward conduction loss. Its 25 ns trr and 0.92 V VF at 1.0 A enable high-frequency operation up to 100 kHz in flyback and boost topologies.
The SMA package provides a thermal resistance of 90°C/W (junction-to-ambient), supporting continuous 1.0 A operation at TL ≤ 110°C per derating curve. AEC-Q101 Rev_C qualification confirms suitability for under-hood automotive environments with operating junction temperatures from –55°C to +150°C.

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 | Same 200 V VRRM, but VF = 0.95 V @ 1 A and trr = 30 ns; TO-277 package (lower RthJC) | Higher thermal performance in high-ambient industrial drives; not AEC-Q101 qualified | Select when board-level thermal resistance dominates over qualification needs |
| MBR120LSFT1G | Schottky architecture: VF = 0.45 V @ 1 A, but VRRM = 20 V only; no reverse recovery | Only suitable for low-voltage (<24 V) outputs; cannot replace ES1D-LS in 200 V blocking roles | Choose only for ultra-low-loss 12 V secondary-side rectification, not primary-side replacement |
Compared with STTH1R02UF and MBR120LSFT1G, ES1D-LS uniquely balances AEC-Q101 compliance, 200 V blocking, and 25 ns trr in the compact SMA footprint-making it optimal for automotive and space-constrained industrial rectification where qualification and speed are jointly critical.

FAQ
What is the maximum junction temperature for continuous operation of ES1D-LS?
The ES1D-LS is rated for continuous operation with junction temperature ranging from –55°C to +150°C. Its thermal resistance (RthJA = 90°C/W) requires adequate PCB copper area to maintain TJ ≤ 150°C at 1.0 A average current. Derating begins at TL = 110°C per Figure 1 in the datasheet.
Is ES1D-LS pin-compatible with other SMA-packaged rectifiers like ES1B or ES1G?
Yes - ES1D-LS shares the identical SMA (DO-214AC) package outline and anode/cathode terminal layout with ES1B, ES1G, and ES1J. All use the same polarity marking (cathode band) and mechanical dimensions, enabling direct PCB footprint reuse across the ES1x series for voltage-scaling designs.
Does ES1D-LS support reflow soldering per J-STD-020?
Yes - ES1D-LS is qualified for standard Pb-free reflow soldering per J-STD-020, with a peak temperature of 260°C for 30 seconds. Its UL 94V-0 molding compound and glass passivation ensure integrity through multiple thermal cycles without delamination or parameter shift.
How does the 25 ns reverse recovery time impact EMI in switching power supplies?
The 25 ns trr reduces high-frequency ringing during diode turn-off, lowering radiated EMI in the 30–100 MHz band. This allows smaller input filter components and eases EMC compliance in automotive and industrial converters without requiring snubbers or additional shielding.
