Product details
Overview
PNE20040EP-QX from Nexperia is a hyperfast switching recovery rectifier optimized for automotive-grade power conversion, featuring 200 V repetitive peak reverse voltage, 4 A average forward current, ≤30 ns reverse recovery time, and AEC-Q101 qualification. It serves as a freewheeling or reverse polarity protection diode in high-frequency DC/DC stages of Engine Control Units (ECUs) and other under-hood electronics.
For engineers reviewing the PNE20040EP-QX datasheet, PNE20040EP-QX pinout, PNE20040EP-QX application, or PNE20040EP-QX equivalent, key selection criteria include trr ≤30 ns at 25 °C, VF = 720–780 mV @ 4 A / 125 °C, IR ≤10 µA @ 200 V / 125 °C, and CFP5 (SOD128) surface-mount package compatibility with high-power-density layouts.
Technical Context
This planar-doped, Pt-lifetime-controlled silicon rectifier uses clip-bond technology to achieve low thermal resistance (Rth(j-sp) = 115 K/W on 1 cm² cathode pad) and high surge capability (IFSM = 80 A). Its hyperfast recovery is defined by step-recovery trr ≤30 ns and ramp-recovery trr ≤17 ns under standardized test conditions (IF = 0.5 A, IR = 1 A, dIF/dt = 100 A/µs).
The device operates across –55 °C to +175 °C junction temperature, with derated VRRM down to ~140 V at Tj = 125 °C and full 200 V rating only at Tj ≤25 °C. Reverse leakage remains tightly controlled: IR ≤1 µA @ 200 V / 25 °C and ≤10 µA @ 200 V / 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage sustainable without breakdown; defines safe blocking range in 24 V automotive systems. |
| IF(AV) | 4 A - Average forward current at δ = 0.5, f = 20 kHz square wave, Tsp ≤158 °C; supports continuous operation in high-duty-cycle freewheeling paths. |
| trr | ≤30 ns - Measured step-recovery time at IF = 0.5 A, IR = 1 A, Tj = 25 °C; enables >1 MHz switching in synchronous rectification and snubberless designs. |
| VF @ 4 A / 125 °C | 720–780 mV - Forward voltage drop under elevated temperature; directly impacts conduction loss and thermal design margin in ECU power rails. |
| IR @ 200 V / 125 °C | 1.5–10 µA - Reverse leakage current at max rated voltage and high junction temperature; critical for low-power standby and battery-disconnect integrity. |
| Rth(j-sp) | 115 K/W - Thermal resistance from junction to solder point on 1 cm² cathode pad; enables efficient heat extraction in compact SMT layouts. |
| Qrr | 9 nC - Reverse recovery charge at dIF/dt = 100 A/µs, IF = 1 A, VR = 30 V, Tj = 25 °C; determines turn-off switching loss and EMI generation. |
Pinout & Package
Encapsulated in a CFP5 (SOD128) surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm with 4 mm lead pitch, the PNE20040EP-QX features a flat, low-inductance construction optimized for high-frequency PCB layout and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; electrically and thermally connected to large internal clip; requires ≥1 cm² copper pad for optimal thermal performance. |
| 2 (A) | Anode | Current entry terminal; smaller metallization area; routed with minimal loop inductance for fast-switching node integrity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use per stress test standard; supports functional safety-aware system design without additional qualification effort. |
| trr ≤30 ns | Enables high-frequency (>500 kHz) operation in buck-derived converters while minimizing switching loss and EMI during diode turn-off transitions. |
| Clip-bond construction | Reduces parasitic inductance and improves thermal transfer vs. wire-bonded equivalents; supports higher IFSM (80 A) and stable power cycling. |
| Low VF drift with temperature | VF increases only ~140 mV from 25 °C to 125 °C at 4 A; simplifies thermal compensation in closed-loop power supplies. |
| CFP5 (SOD128) footprint | Standardized 2-pin SMD outline compatible with JEDEC MS-012AC; allows drop-in replacement in existing high-density automotive PCB designs. |
Applications
| Engine Control Unit (ECU) Power Stage | Automotive DC/DC Converter Freewheeling |
|---|---|
|
Use Scenario: High-efficiency 12 V → 5 V/3.3 V buck converter supplying microcontroller core and sensor interfaces in engine bay environments. IC Role / Device Role / Timing Role: Freewheeling diode conducting during low-side switch off-time; must recover before next cycle to prevent shoot-through and voltage spikes. Use Value: trr ≤30 ns ensures clean commutation at 1 MHz switching, reducing output ripple and EMI filter size while maintaining <1% efficiency penalty at full load. |
Use Scenario: 48 V → 12 V bidirectional DC/DC stage in mild hybrid vehicle energy management systems. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed upstream of main converter input; blocks fault currents during battery reversal or jump-start events. Use Value: VRRM = 200 V provides 4× safety margin over nominal 48 V bus, while IR ≤10 µA at 125 °C prevents excessive quiescent drain in parked-state monitoring circuits. |
| On-Board Charger (OBC) Snubber Network | Automotive Lighting Driver Clamp |
|
Use Scenario: Passive RCD snubber across IGBTs in OBC AC/DC front-end to suppress voltage overshoot during turn-off. IC Role / Device Role / Timing Role: Fast recovery clamp diode that conducts transient energy into snubber capacitor; must reset rapidly before next switching edge. Use Value: Qrr = 9 nC minimizes stored charge dissipation in snubber resistor, lowering thermal stress and enabling smaller, lower-cost snubber components. |
Use Scenario: LED headlamp driver with inductive load switching, requiring flyback energy clamping during PWM dimming transitions. IC Role / Device Role / Timing Role: Hyperfast clamp diode absorbing inductive kickback from LED string when MOSFET turns off. Use Value: VF = 720–780 mV @ 125 °C ensures predictable clamping voltage and low conduction loss during brief flyback pulses, preserving LED lifetime and thermal stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06S | 600 V VRRM, 4 A IF(AV), trr = 35 ns, TO-277 package | Higher voltage rating suits 48 V+ systems but larger footprint and higher VF (1.15 V @ 4 A / 125 °C) increases conduction loss | Select when >200 V blocking is required and board space permits TO-277 mounting. |
| ON Semiconductor MUR420 | 200 V VRRM, 4 A IF(AV), trr = 35 ns, DO-214AC (SMA) package | Non-AEC-Q101; higher Rth(j-a) = 50 K/W limits power density; VF = 950 mV @ 4 A / 25 °C degrades at temperature | Acceptable for non-automotive industrial use where qualification and thermal performance are secondary. |
Compared with STTH4L06S and MUR420, the PNE20040EP-QX delivers superior thermal performance (Rth(j-sp) = 115 K/W), tighter VF consistency across temperature, and automotive qualification-making it the preferred choice for space-constrained, high-reliability ECU and OBC designs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PNE20040EP-QX has a maximum junction temperature (Tj) rating of 175 °C, validated per AEC-Q101. Continuous operation at this limit requires strict thermal management: Rth(j-sp) ≤115 K/W on a 1 cm² cathode pad and ambient temperature control to avoid exceeding Tj in steady-state conditions.
Is the CFP5 (SOD128) package compatible with standard reflow profiles?
Yes-the CFP5 package is qualified for lead-free reflow per J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. The symmetric 2-pin layout and low mass enable uniform heating and minimize tombstoning risk in automated assembly.
How does reverse recovery charge (Qrr) impact EMI in high-frequency converters?
Qrr = 9 nC directly contributes to high di/dt during turn-off, generating broadband EMI. Lower Qrr reduces the amplitude and spectral content of switching noise, easing compliance with CISPR 25 Class 5 requirements common in automotive power supplies without adding snubber complexity.
Can PNE20040EP-QX replace slower rectifiers like 1N5822 in existing designs?
Yes-if board layout accommodates the CFP5 footprint and thermal design accounts for its lower VF (720–780 mV vs. ~850 mV for 1N5822 at 4 A). The faster trr (≤30 ns vs. ~100 ns) improves efficiency above 200 kHz but may require gate drive tuning to avoid cross-conduction in synchronous topologies.
