Product details
Overview
ES1GRX from Nexperia is a hyperfast PN-junction rectifier diode rated for 400 V repetitive peak reverse voltage and 1 A average forward current, featuring 25 ns maximum reverse recovery time (trr), 1050 mV typical forward voltage at 1 A/25 °C, and low 14 pF junction capacitance - deployed in high-frequency DC/DC converters and freewheeling paths in switch-mode power supplies.
For engineers reviewing the ES1GRX datasheet, ES1GRX pinout, ES1GRX application, or ES1GRX equivalent, this device is selected for designs requiring fast switching, low forward loss, and compact SMD integration in space-constrained industrial and consumer power stages.
Technical Context
This PN-rectifier uses platinum-doped lifetime control to achieve hyperfast recovery with minimal tail current, enabling efficient operation in 20–500 kHz switching topologies. Its planar die structure and clip-bond packaging ensure low thermal resistance (105 K/W junction-to-solder-point) and stable performance up to 150 °C junction temperature.
The device operates with defined reverse recovery behavior under ramp and step conditions (trr = 16 ns typ. ramp, 10–25 ns step), exhibits low reverse leakage (≤200 µA at 125 °C/400 V), and maintains consistent VF across -40 °C to +150 °C ambient range - critical for thermally demanding offline and automotive auxiliary power designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification in universal AC/DC front-ends up to 280 VRMS. |
| IF(AV) | 1 A - delivers continuous output current in compact 5–15 W SMPS without forced cooling. |
| trr | ≤25 ns - minimizes switching losses and EMI in high-frequency flyback and buck-derived topologies. |
| VF @ 1 A, 25 °C | 1050 mV typ. - reduces conduction loss and thermal load vs. standard fast recovery diodes. |
| Cd @ 4 V | 14 pF - limits capacitive turn-on current and improves noise immunity in gate-drive snubbers. |
| Rth(j-sp) | 105 K/W - enables direct thermal coupling to PCB copper pour for passive heatsinking. |
| IR @ 400 V, 125 °C | ≤200 µA - ensures low standby power loss in always-on auxiliary rails. |
Pinout & Package
ES1GRX is housed in a CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads optimized for reflow and wave soldering, with cathode-side thermal pad for enhanced heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit path; connected to thermal pad for low Rth(j-sp) and PCB copper pour heatsinking. |
| 2 | Anode (A) | Current entry point; routed to switching node or AC input; low-inductance layout critical for trr performance. |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast recovery | trr ≤25 ns enables >300 kHz operation without excessive switching loss or ringing. |
| Pt-doped lifetime control | Eliminates minority-carrier tail current, reducing EMI and improving efficiency over silicon fast recovery diodes. |
| Clip-bond construction | Increases current-carrying capacity and thermal robustness vs. wire-bonded equivalents in same footprint. |
| Low-profile SOD123W package | 1.0 mm max height allows use in ultra-thin power adapters and LED drivers with strict Z-axis constraints. |
| Reflow/wave solder compatible | Qualified per J-STD-020 and J-STD-002 - supports high-volume automated assembly without lead damage. |
Applications
| AC/DC Adapter Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Input bridge rectification in 5–12 W wall adapters with universal AC input (90–264 VAC). IC Role / Device Role / Timing Role: Primary-side unidirectional current path; handles 50/60 Hz line frequency and high-frequency ripple from PFC stage. Use Value: Low VF and 400 V rating reduce conduction loss and improve no-load efficiency; compact size saves board area. |
Use Scenario: Series protection on 3.3 V/5 V/12 V DC input rails of microcontroller-based modules. IC Role / Device Role / Timing Role: Unidirectional blocking element; conducts only during correct polarity insertion. Use Value: 1 A rating supports typical IoT node loads; 25 ns trr prevents latch-up during hot-plug transients. |
| Freewheeling Diode in Buck Converters | Snubber Network in Flyback Controllers |
|
Use Scenario: Output-stage freewheeling path in 300–500 kHz synchronous buck regulators powering FPGAs or ASICs. IC Role / Device Role / Timing Role: Provides low-loss return path during high-side MOSFET off-time; recovers before next cycle. Use Value: 14 pF capacitance and 25 ns trr minimize voltage overshoot and reduce snubber component count. |
Use Scenario: RC-snubber clamp across primary-side MOSFET in 65–130 kHz flyback converters for LED lighting. IC Role / Device Role / Timing Role: Absorbs inductive energy spike during MOSFET turn-off; must recover before next switching event. Use Value: Fast trr and low VFRM (2.35 V) limit clamping voltage and suppress ringing-induced EMI. |
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 VRRM (200 V), but lower 200 ns trr; TO-220AC package; higher VF (1.15 V). | Requires heatsink; unsuitable for >100 kHz or space-constrained layouts. | Select when cost-sensitive, low-frequency (<100 kHz), and board space is not constrained. |
| Vishay VS-1EWH04-M3 | Same CFP3 package, 400 V, 1 A, but 35 ns trr; higher VF (1.1 V typ.); 200 µA IR at 125 °C. | Slightly slower recovery increases switching loss in >250 kHz designs. | Choose if dual-sourcing required and minor trr degradation is acceptable in existing layouts. |
Compared with MUR120 and VS-1EWH04-M3, ES1GRX offers superior high-frequency efficiency due to its 25 ns trr and 1050 mV VF, while maintaining identical SOD123W footprint - making it optimal for miniaturized, high-efficiency power conversion where thermal and EMI margins are tight.

FAQ
What is the maximum allowable junction temperature for ES1GRX?
The absolute maximum junction temperature is 150 °C, verified per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of Pt-doped lifetime control and increased reverse leakage. Derating curves in Figures 8–10 define safe IF(AV) versus ambient or solder-point temperature under defined PCB mounting conditions.
Can ES1GRX be used in automotive applications?
No - ES1GRX is not AEC-Q101 qualified and lacks automotive-grade screening, traceability, or extended temperature validation beyond 150 °C junction. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use in automotive systems requires formal qualification and carries full customer liability.
How does the CFP3 (SOD123W) package improve thermal performance over standard SOD-123?
The CFP3 variant features an exposed cathode thermal pad and clip-bond interconnect, achieving Rth(j-sp) = 105 K/W - 30% lower than standard SOD-123 (typically ~150 K/W). This allows direct thermal coupling to large PCB copper areas, reducing junction temperature rise by up to 15 °C at 1 A DC under identical layout conditions.
Is ES1GRX suitable for zero-voltage switching (ZVS) circuits?
Yes - its 25 ns trr and low stored charge (Qr not specified but implied by trr <25 ns and Pt doping) enable reliable soft-switching in resonant LLC and phase-shifted full-bridge topologies. However, ZVS timing margins must be validated against measured Qr and circuit parasitics, as datasheet does not publish Qr or reverse recovery charge values.
