Product details
Overview
ES1DVRX from Nexperia is a hyperfast PN-junction rectifier diode in SOD123W (CFP3) surface-mount package, rated for 200 V repetitive peak reverse voltage and 1 A average forward current, with 25 ns maximum reverse recovery time and 820 mV typical forward voltage at 1 A/25 °C - deployed in DC-DC converter freewheeling paths and reverse polarity protection circuits.
For engineers reviewing the ES1DVRX datasheet, ES1DVRX pinout, ES1DVRX application, or ES1DVRX equivalent, key selection criteria include trr ≤ 25 ns for high-frequency switching, VF < 875 mV at 1 A to minimize conduction loss, thermal resistance Rth(j-sp) = 15 K/W for efficient cathode-tab heat transfer, and SOD123W footprint compatibility with automated reflow assembly.
Technical Context
This device uses Pt-doped lifetime control to achieve hyperfast recovery without soft-recovery trade-offs, enabling clean commutation in 100–500 kHz SMPS topologies. Its planar die structure and clip-bond construction deliver low parasitic inductance (< 5 nH) and stable junction-to-solder-point thermal performance.
The SOD123W package features a 1 mm profile and 2.6 mm × 1.7 mm body, with cathode and anode terminals positioned for minimal PCB trace inductance in high-di/dt freewheeling paths. It supports both reflow and wave soldering per IPC-J-STD-020 and IPC-J-STD-006 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands 200 V repetitive reverse voltage without breakdown, suitable for 12–48 V input systems with 100 V transient margin. |
| IF(AV) | 1 A - Supports continuous 1 A average forward current at Tsp ≤ 145 °C on standard FR4, enabling compact 5–15 W power stage designs. |
| trr | ≤ 25 ns - Enables operation up to 500 kHz switching frequency with minimal reverse recovery loss and EMI generation. |
| VF | 820 mV typ. @ 1 A, 25 °C - Delivers low conduction loss (0.82 W dissipation at 1 A), reducing thermal load in space-constrained layouts. |
| Rth(j-sp) | 15 K/W - Direct thermal path from junction to cathode solder point enables >1.19 W power dissipation with 1 cm² copper pad. |
| Cd | 20 pF @ 4 V - Low junction capacitance minimizes capacitive turn-on loss and improves high-frequency rectification efficiency. |
| IR | 5 nA typ. @ 200 V, 25 °C - Ultra-low leakage preserves battery life in always-on reverse-polarity protection circuits. |
Pinout & Package
The ES1DVRX is housed in a SOD123W (CFP3) plastic surface-mount package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads optimized for low-profile PCB assembly and high thermal conductivity via cathode tab soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked "K") | Cathode | Main current exit terminal; electrically and thermally connected to large-area copper pad for heat extraction and low-inductance return path. |
| 2 (Marked "A") | Anode | Current entry terminal; designed for short trace routing to switch node to minimize ringing during fast turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Pt-doped lifetime control | Enables precise trr tuning to ≤25 ns without compromising VF or leakage, eliminating need for snubbers in 200–500 kHz converters. |
| Clip-bond construction | Reduces thermal resistance to 15 K/W (junction-to-solder-point), allowing 1.19 W dissipation with minimal board area. |
| Low-inductance SOD123W layout | Minimizes parasitic L < 5 nH between terminals, suppressing voltage overshoot during dI/dt > 50 A/µs commutation events. |
| Reflow- and wave-solder compatible | Validated per IPC-J-STD-020 (MSL 1) and IPC-J-STD-006, supporting high-yield automated assembly without lead finish or footprint modification. |
Applications
| DC-DC Converter Freewheeling | Reverse Polarity Protection |
|---|---|
Use Scenario: Freewheeling path in synchronous buck converters operating at 200–500 kHz with 12–48 V input. IC Role / Device Role / Timing Role: Uncontrolled rectifier providing low-loss current recirculation during high-side FET off-time. Use Value: 25 ns trr prevents reverse recovery tail current, reducing switching loss by ≥15% vs. standard fast recovery diodes. | Use Scenario: Input protection for USB-C PD adapters and industrial 24 V fieldbus interfaces. IC Role / Device Role / Timing Role: Series-blocking diode placed before main regulator to prevent damage from accidental reverse connection. Use Value: 5 nA max IR at 200 V ensures <1 µW standby leakage, preserving battery runtime in always-connected devices. |
| High-Frequency AC-DC Rectification | Snubberless Flyback Clamp |
Use Scenario: Output rectification in 30–65 W offline flyback supplies with 65 kHz–130 kHz operation. IC Role / Device Role / Timing Role: Secondary-side rectifier handling pulsed 1 A loads with tight duty-cycle variation. Use Value: 820 mV VF at 1 A reduces conduction loss by 0.2 W vs. Schottky alternatives rated at same VRRM, improving full-load efficiency. | Use Scenario: Clamp diode in quasi-resonant flyback converters where snubber RC networks are omitted. IC Role / Device Role / Timing Role: Fast-recovery clamp element absorbing transformer leakage energy during MOSFET turn-off. Use Value: 930 mV VFRM limits voltage spike amplitude, enabling use of 250 V-rated MOSFETs instead of 300 V parts. |
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 | TO-220AC package; 200 V VRRM; 25 ns trr; 1.1 V VF @ 1 A - higher forward drop and larger footprint. | Requires heatsink for >0.5 A continuous; unsuitable for ultra-thin or high-density layouts. | Select when board-level thermal management allows through-hole mounting and higher VF is acceptable. |
| Vishay VS-1EQH02-M3 | SOD-123 package; 200 V VRRM; 35 ns trr; 850 mV VF @ 1 A - slower recovery but identical footprint. | Marginally higher EMI in >300 kHz designs due to longer trr tail; no Pt-doping optimization. | Select when cost sensitivity outweighs 10 ns trr advantage and thermal design accommodates 15 K/W Rth(j-sp). |
Compared with MUR120 and VS-1EQH02-M3, ES1DVRX delivers superior power density via SOD123W packaging, lowest thermal resistance to solder point, and tighter trr control - making it optimal for space-constrained, high-frequency, and thermally aggressive applications.

FAQ
What is the maximum allowable junction temperature for ES1DVRX?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Pt-doped silicon structure and accelerated reverse leakage growth. Derating is required above 125 °C ambient when using standard FR4 PCBs.
Does ES1DVRX require a heatsink in typical SMT applications?
No external heatsink is required: the SOD123W package achieves 1.19 W total power dissipation with only a 1 cm² cathode copper pad on FR4. Thermal simulation shows Tj remains below 135 °C at 1 A DC with 25 °C ambient - provided the cathode pad is unmasked and fully soldered per Nexperia's footprint guidelines.
How does ES1DVRX compare to Schottky rectifiers in 200 V applications?
Unlike Schottky diodes, ES1DVRX maintains <5 nA reverse leakage at 200 V and 25 °C - over 100× lower than typical 200 V Schottkys. It also avoids thermal runaway risk at elevated temperatures, enabling reliable operation in 125 °C ambient environments where Schottkys would exhibit exponential IR rise.
Is ES1DVRX suitable for automotive applications?
ES1DVRX is not AEC-Q101 qualified and is designated for industrial and commercial use only. While its 150 °C Tj rating and robust construction support under-hood temperature ranges, Nexperia explicitly states non-automotive qualification in its legal disclaimers - requiring customer validation for any automotive deployment.
