Product details
Overview
ES2DVRX from NXP Semiconductors is a hyperfast PN-junction rectifier in SOD123W package, rated for 200 V repetitive peak reverse voltage and 2 A average forward current, with 25 ns maximum reverse recovery time and 890 mV typical forward voltage at 2 A/25 °C - deployed in high-frequency DC-DC converter freewheeling paths.
For engineers reviewing the ES2DVRX datasheet, ES2DVRX pinout, ES2DVRX application, or ES2DVRX equivalent, key selection criteria include trr ≤ 25 ns for reduced switching loss, VF ≤ 950 mV at 2 A/25 °C for thermal efficiency, Rth(j-sp) = 15 K/W for cathode-tab thermal management, and SOD123W footprint compatibility with space-constrained power stages.
Technical Context
This device uses planar die construction with platinum doping for precise lifetime control, enabling hyperfast recovery without soft-recovery trade-offs. Its clip-bond packaging achieves low inductance and high power density while maintaining 1 mm profile height.
The diode operates with defined junction temperature limits (Tj ≤ 150 °C), supported by validated thermal resistance values: Rth(j-a) = 170 K/W on standard FR4 and Rth(j-sp) = 15 K/W to cathode solder point - critical for pulsed-current reliability in SMPS output stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input rectification up to 140 VRMS or 200 VDC bus rails without avalanche stress |
| IF(AV) | 2 A - delivers continuous output current in 20 kHz square-wave SMPS designs with Tsp ≤ 139 °C |
| trr | ≤ 25 ns - minimizes reverse recovery charge (Qr) and associated switching losses in hard-switched topologies |
| VF @ 2 A, 25 °C | 890–950 mV - enables low conduction loss and <1.2 W total dissipation at full load on standard PCB |
| Rth(j-sp) | 15 K/W - allows direct thermal coupling to large copper pour via cathode tab, improving transient thermal response |
| IR @ 200 V, 125 °C | 1.5–20 µA - ensures low leakage in high-temp hold-up or reverse-polarity protection circuits |
| Cd @ 4 V | 20 pF - reduces capacitive turn-on loss and EMI generation during high-dV/dt commutation |
Pinout & Package
SOD123W surface-mount plastic package with 1 mm typical height, 2.4 × 3.7 mm body, and flat leads optimized for reflow soldering per IPC-7095 guidelines. Cathode tab provides primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Main current exit terminal and primary thermal interface - connects to PCB copper pour for heat extraction |
| 2 | A (anode) | Current entry terminal - routed with minimal loop area to reduce EMI in high-dI/dt freewheeling paths |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast recovery | trr ≤ 25 ns enables operation in 500 kHz+ switch-mode supplies without excessive ringing or loss |
| Clip-bond construction | Reduces package inductance below 1.5 nH and increases current-carrying capacity vs. wire-bond equivalents |
| Pt-doped lifetime control | Ensures consistent trr across temperature and batch, eliminating need for external snubbers in most applications |
| Low-profile SMD package | 1 mm height allows integration into ultra-thin power modules and stacked PCB assemblies |
Applications
| DC-DC Converter Freewheeling | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in synchronous or asynchronous buck converters operating at 20–500 kHz. IC Role / Device Role / Timing Role: Freewheeling diode conducting during high-side switch off-time; defines minimum on-time capability via trr. Use Value: 25 ns trr and 890 mV VF reduce conduction + recovery losses by >15% vs. standard fast recovery diodes at 2 A/100 kHz. |
Use Scenario: Input protection circuit blocking reverse battery connection in 12–48 V industrial power supplies. IC Role / Device Role / Timing Role: Series-blocking diode placed before main regulator; conducts only during correct polarity insertion. Use Value: 200 V VRRM withstands load-dump transients; 1.5 µA IR at 125 °C prevents battery drain in hot environments. |
| High-Frequency Rectification | Snubberless Flyback Clamp |
|
Use Scenario: Output rectification in isolated flyback or forward converters where compact size and low VF are critical. IC Role / Device Role / Timing Role: Main output rectifier handling continuous 2 A DC load with 20 kHz square-wave excitation. Use Value: 2 A IF(AV) rating and 105 K/W Rth(j-sp) enable stable operation without heatsink on 1 cm² cathode pad. |
Use Scenario: Clamp diode in RCD snubber networks for MOSFET drain protection in offline SMPS. IC Role / Device Role / Timing Role: Fast-turn-off clamp path absorbing transformer leakage energy during MOSFET turn-off. Use Value: 930 mV VFRM peak forward recovery voltage limits voltage overshoot; 20 pF Cd reduces capacitive coupling to gate drive. |
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 MURS220T3G | Same SOD123W package, 200 V/2 A rating, but trr = 35 ns (vs. 25 ns) and VF = 950 mV @ 2 A/25 °C | Acceptable in ≤200 kHz designs; higher trr increases Qrr-related loss in high-frequency flybacks | Select when cost sensitivity outweighs 10 ns trr advantage and thermal margin is ample |
| Vishay VSKY220HM3/H | 200 V/2 A, trr = 20 ns, but VF = 1.05 V @ 2 A/25 °C and Rth(j-a) = 190 K/W (vs. 170 K/W) | Better recovery speed but higher conduction loss; less effective thermal spreading on standard FR4 | Prefer where trr dominates system loss budget and board layout allows larger thermal pad |
Compared with MURS220T3G and VSKY220HM3/H, ES2DVRX offers optimal balance of trr (≤25 ns), VF (≤950 mV), and Rth(j-sp) (15 K/W), making it especially suitable for thermally constrained, high-frequency freewheeling in compact DC-DC modules.

FAQ
What is the maximum allowable junction temperature for ES2DVRX?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Pt-doped silicon structure and accelerated IR drift. Derating curves in Figures 8–10 define safe IF(AV) limits based on ambient or solder-point temperature.
Does ES2DVRX require a heatsink in typical 2 A applications?
No external heatsink is required when mounted on an FR4 PCB with a 1 cm² cathode thermal pad, as Rth(j-sp) = 15 K/W enables sufficient heat transfer. At 2 A/25 °C ambient, junction temperature rise is ~45 °C (2 A² × 0.9 Ω × 15 K/W ≈ 54 °C), well within the 150 °C limit.
How does the SOD123W package compare to SMA in thermal performance?
SOD123W offers lower Rth(j-sp) (15 K/W) than standard SMA (≈25–30 K/W) due to its clip-bond cathode tab design, enabling more direct thermal conduction to PCB copper. Its 1 mm height also improves airflow clearance in stacked power modules where SMA's 2.3 mm profile causes interference.
Can ES2DVRX replace a Schottky diode in 24 V input rectification?
Only if reverse voltage exceeds 100 V - ES2DVRX's 200 V VRRM supports higher bus voltages than typical 45 V Schottkys, but its 890 mV VF is higher than Schottky's ~450 mV. It is preferred over Schottky where high-temperature stability (IR < 20 µA at 125 °C) or 200 V surge tolerance is required.
