Product details
Overview
ES1DRX from Nexperia is a hyperfast PN-junction rectifier diode rated for 200 V repetitive peak reverse voltage and 1 A average forward current, featuring 25 ns maximum reverse recovery time and low forward voltage drop (845–930 mV at 1 A, 25 °C), housed in a compact SOD123W (CFP3) surface-mount package with 1 mm typical height-used in high-frequency switching power supplies and freewheeling paths.
For engineers reviewing the ES1DRX datasheet, ES1DRX pinout, ES1DRX application, or ES1DRX equivalent, this page delivers verified electrical parameters, thermal performance data, soldering footprint details, and real-world use context for fast-switching rectification in space-constrained DC/DC converters and protection circuits.
Technical Context
This device employs planar die construction with platinum doping for precise lifetime control, enabling hyperfast recovery (trr ≤ 25 ns) and low stored charge-critical for minimizing switching losses in high-frequency (>100 kHz) topologies. Its clip-bond packaging ensures low thermal resistance (Rth(j-sp) = 15 K/W) and high power capability despite its small 2.6 mm × 1.7 mm footprint.
The diode operates across –55 °C to +150 °C junction temperature range, supports both reflow and wave soldering per IPC-J-STD-020/001, and maintains stable reverse leakage (<20 µA at 125 °C, 200 V) and capacitance (17 pF at 4 V) under dynamic bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive reverse voltage up to 200 V without breakdown, suitable for 100 V AC input rectification with safety margin. |
| IF(AV) | 1 A - Sustains continuous forward current of 1 A at Tsp ≤ 140 °C, enabling use in compact 5–12 W SMPS outputs. |
| trr | ≤25 ns - Ultra-fast reverse recovery minimizes turn-off loss and EMI in hard-switched flyback and buck converters. |
| VF | 845–930 mV @ 1 A, 25 °C - Low conduction loss improves efficiency in low-voltage output stages (e.g., 3.3 V/5 V rails). |
| Rth(j-sp) | 15 K/W - Low junction-to-solder-point thermal resistance enables direct heat transfer to PCB copper, supporting high-power density layouts. |
| Cd | 17 pF @ 4 V, 1 MHz - Low junction capacitance reduces capacitive switching loss and noise coupling in high-dv/dt environments. |
| IR | ≤20 µA @ 200 V, 125 °C - Controlled leakage ensures stable blocking behavior in elevated-temperature industrial applications. |
Pinout & Package
The ES1DRX is packaged in the SOD123W (CFP3) surface-mount plastic case: 2.6 mm × 1.7 mm × 1.0 mm body size, flat leads, single-sided copper-compatible footprint, optimized for automated assembly and thermal dissipation via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to internal N-type region; serves as primary heat path to PCB via large-area solder pad; polarity reference for forward conduction. |
| 2 | Anode (A) | Connected to internal P-type region; carries forward current into the device; smaller thermal contribution than cathode terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast recovery | trr ≤ 25 ns enables operation in >500 kHz switching converters without excessive loss or ringing. |
| Clip-bond construction | Reduces bond wire inductance and improves thermal conduction from die to cathode tab, enhancing reliability under surge conditions. |
| Pt-doped lifetime control | Ensures consistent trr and Qr across temperature and lot, critical for predictable EMI and efficiency in production designs. |
| Low-profile SMD package | 1 mm max height allows integration beneath low-clearance heatsinks or in ultra-thin power modules. |
| Reflow/wave solder compatible | Validated per IPC-J-STD-020 and J-STD-001, eliminating need for special process qualification in high-volume manufacturing. |
Applications
| AC-DC Adapter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 W offline flyback adapters powering IoT sensors and USB-C accessories. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer secondary AC to regulated DC; switches at 65–130 kHz with minimal reverse recovery loss. Use Value: 25 ns trr and 845 mV VF reduce conduction and switching losses by ~12% vs. standard FR1 diodes, improving no-load efficiency and thermal margin. | Use Scenario: Input protection for 12 V/24 V industrial controllers exposed to field wiring errors or battery reversal. IC Role / Device Role / Timing Role: Series-blocking element placed before LDO or DC/DC converter input; conducts only during correct polarity, clamping reverse faults. Use Value: 200 V VRRM provides 2× safety margin over 24 V systems; low VF limits voltage drop to <0.9 V at 1 A, preserving input headroom. |
| Freewheeling Diode in Buck Converters | Snubberless Flyback Clamp |
Use Scenario: Freewheel path in 3–12 V, 1–3 A synchronous buck regulators for FPGA I/O rails and microcontroller cores. IC Role / Device Role / Timing Role: Provides low-impedance return path for inductor current during high-side switch off-time; recovers before next cycle begins. Use Value: 10 ns step-recovery trr prevents shoot-through risk in high-frequency (≥1 MHz) operation and reduces snubber component count. | Use Scenario: Clamp diode in discontinuous-mode flyback converters where RCD snubbers are omitted for cost and size reduction. IC Role / Device Role / Timing Role: Absorbs transformer leakage energy during MOSFET turn-off; must recover rapidly to avoid voltage doubling on subsequent cycles. Use Value: 930 mV VFRM peak forward recovery voltage limits clamp overshoot; 17 pF Cd minimizes capacitive feedthrough into control circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120 | Same 200 V VRRM, 1 A IF(AV), but trr = 35 ns (vs. 25 ns); TO-220AC package (vs. SOD123W). | Requires through-hole mounting and larger board area; higher thermal mass slows transient response. | Select when legacy through-hole layout exists or when higher surge rating (IFSM = 50 A) is required. |
| Vishay VS-1EWH02-M3 | 200 V VRRM, 1 A IF(AV), trr = 20 ns; same SOD123W package; VF = 950 mV @ 1 A, 25 °C. | Marginally faster recovery but higher forward drop increases conduction loss in high-duty-cycle apps. | Select when trr < 20 ns is mandatory and 150 mV higher VF is acceptable for thermal budget. |
Compared with MUR120 and VS-1EWH02-M3, ES1DRX offers the best balance of speed (25 ns), low VF (845 mV), and ultra-compact SMD form factor-making it optimal for modern high-density, high-efficiency power supplies where board space and thermal management are constrained.

FAQ
What is the maximum allowable junction temperature for ES1DRX?
The absolute maximum junction temperature is 150 °C, as defined in the limiting values table. Operation above this threshold risks permanent degradation of the PN junction and accelerated parameter drift. Derating curves in Figures 8–10 show that sustained 1 A average current requires ambient temperatures below 75 °C on standard FR4 PCBs.
Does ES1DRX support lead-free reflow soldering profiles?
Yes-ES1DRX is qualified for lead-free reflow per IPC-J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The SOD123W package outline and recommended footprint (Figure 16) ensure reliable wetting and mechanical integrity under standard JEDEC profiles.
How does the Pt-doping affect reverse recovery behavior?
Platinum doping controls carrier lifetime in the silicon bulk, reducing stored charge (Qr) and enabling tightly controlled, low-dispersion reverse recovery (trr ≤ 25 ns). This results in lower switching loss and reduced EMI compared to gold-doped or non-doped alternatives, especially at elevated temperatures.
Can ES1DRX replace a standard 1N4007 in a 24 V power supply?
No-while both handle 1 A average current, the 1N4007 has 30 µs trr and 1000 V VRRM, making it unsuitable for high-frequency switching. ES1DRX's 25 ns trr and low VF are optimized for SMPS, not line-frequency rectification; substituting it into 50/60 Hz circuits offers no benefit and risks overstress due to higher dv/dt sensitivity.
