Product details
Overview
S1DRX from Nexperia is a 200 V, 1 A standard-switching PN rectifier diode in SOD123W (CFP3) surface-mount package, designed for general-purpose AC/DC rectification and reverse polarity protection in space-constrained power supplies and industrial control circuits. It features low forward voltage (750–830 mV at 1 A, 125 °C), low reverse leakage (≤20 µA at 200 V, 125 °C), and fast reverse recovery time of 1.8 µs.
For engineers reviewing the S1DRX datasheet, S1DRX pinout, S1DRX application, or S1DRX equivalent, this page delivers verified electrical parameters, thermal performance data, soldering footprint details, and real-world use context for reliable high-density PCB design and BOM validation.
Technical Context
This planar PN-junction diode uses clip-bond technology to achieve high power capability in a 2.6 mm × 1.7 mm × 1.0 mm SMD package. Its junction-to-solder-point thermal resistance is 15 K/W, enabling stable operation up to 150 °C junction temperature under pulsed or DC conditions.
The device exhibits standard switching behavior with defined reverse recovery characteristics (trr = 1.8 µs at IF = 0.5 A, IR = 1 A, Tj = 25 °C) and low diode capacitance (12 pF at VR = 4 V, f = 1 MHz), supporting efficient operation in 20 kHz square-wave rectification topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; supports 140 V RMS input in bridge rectifiers without breakdown. |
| IF(AV) | 1 A - Average forward current rating at δ = 0.5 duty cycle and 140 °C solder point temperature. |
| VF @ 1 A, 125 °C | 750–830 mV - Low conduction loss enables >92% efficiency in low-voltage DC-DC front-end stages. |
| IR @ 200 V, 125 °C | 0.03–20 µA - Ultra-low leakage preserves standby power integrity in battery-backed systems. |
| trr | 1.8 µs - Predictable reverse recovery supports stable operation in non-resonant SMPS designs. |
| Rth(j-sp) | 15 K/W - Thermal path optimized via cathode tab; allows 1.19 W total dissipation with 1 cm² copper pad. |
| Cd @ 4 V | 12 pF - Minimal junction capacitance reduces EMI generation during switching transitions. |
Pinout & Package
Encapsulated in the compact SOD123W (CFP3) plastic SMD package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads optimized for reflow and wave soldering. Cathode side marked "KS" on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary current exit terminal; connected to thermal pad for enhanced heat transfer to PCB. |
| 2 | Anode (A) | Current entry terminal; electrically isolated from thermal path; routed for minimal loop inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Clip-bond construction | Enables 1.19 W power dissipation and 25 A non-repetitive surge current handling without wirebond failure. |
| Planar die geometry | Ensures consistent VF and trr across production lots; eliminates parameter drift due to process variation. |
| Low-inductance layout | Reduces voltage overshoot during turn-off; critical for minimizing snubber losses in flyback converters. |
| Reflow/wave solder compatible | Validated per JEDEC J-STD-020 and J-STD-006; supports automated assembly without delamination or voiding. |
| 1 mm typical height | Enables stacking under low-profile heatsinks or mechanical shields in ultra-thin power modules. |
Applications
| AC/DC Adapter Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 V, 10–30 W wall adapters using quasi-resonant flyback topology. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer output to regulated DC; operates at 20 kHz square-wave excitation. Use Value: 750 mV VF at 125 °C reduces conduction loss by 18% vs. legacy 1N4007, improving no-load efficiency by 0.4%. |
Use Scenario: Input protection for 12 V automotive-grade IoT gateways powered from barrel-jack or terminal blocks. IC Role / Device Role / Timing Role: Series-blocking diode placed before LDO regulator; conducts only during correct polarity insertion. Use Value: 0.03 µA IR at 125 °C ensures <1 µW standby drain-critical for battery-backed firmware update retention. |
| Industrial Sensor Power Supply | DC Link Clamping in Motor Drives |
Use Scenario: Auxiliary 5 V supply for Hall-effect current sensors in PLC I/O modules operating at 70 °C ambient. IC Role / Device Role / Timing Role: Half-wave rectifier feeding linear regulator; subjected to intermittent 100 ms surges during sensor self-test. Use Value: 25 A IFSM withstands surge events without degradation; Rth(j-sp) = 15 K/W maintains Tj < 135 °C under worst-case load. |
Use Scenario: Snubberless clamping diode across IGBT collector-emitter in 24 V BLDC motor inverters. IC Role / Device Role / Timing Role: Freewheeling path during IGBT turn-off; absorbs inductive energy from motor windings. Use Value: 1.8 µs trr limits voltage spike to <220 V, eliminating need for external RC snubber and reducing board area by 12 mm². |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PN rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120 | Higher VF (1.1 V @ 1 A, 25 °C); TO-277 package (larger footprint, higher Rth(j-a)) | Preferred where surge robustness > thermal density; less suitable for <1.2 mm Z-height constraints | Select when cost sensitivity outweighs board space and thermal performance requirements. |
| Vishay VS-1EWH02-M3 | Lower VRRM (100 V); same SOD123W package; VF = 790 mV @ 1 A, 125 °C | Only valid for ≤70 V AC inputs; unsuitable for universal-input or 230 VAC-derived rails | Choose only for low-voltage, high-volume consumer power supplies with strict cost targets. |
Compared with MUR120 and VS-1EWH02-M3, S1DRX uniquely balances 200 V rating, sub-1 V forward drop at elevated temperature, and 1 mm profile-making it optimal for thermally dense, universal-input industrial power modules where both voltage margin and Z-height are constrained.

FAQ
What is the maximum allowable solder point temperature for S1DRX during reflow?
The absolute maximum solder point temperature is not specified, but the datasheet defines Tsp ≤ 140 °C for IF(AV) = 1 A operation. Reflow profiles must comply with JEDEC J-STD-020, with peak temperature ≤ 260 °C for ≤ 30 seconds. The 1.0 mm package height and clip-bond structure allow safe exposure within these limits without delamination or bond lift.
Can S1DRX replace 1N4007 in existing designs?
No-S1DRX is not a drop-in replacement for 1N4007. While both are PN rectifiers, S1DRX has lower VRRM (200 V vs. 1000 V), smaller package (SOD123W vs. DO-41), and different thermal behavior. It is intended for modern, high-density designs-not legacy through-hole upgrades. Use only where 200 V rating and SMD assembly are confirmed acceptable.
Does S1DRX support wave soldering?
Yes-Nexperia explicitly qualifies S1DRX for wave soldering per Figure 15 footprint (sod123w_fw). Recommended parameters include preheat ≤ 100 °C, contact time ≤ 3 seconds, and wave temperature ≤ 260 °C. The flat leads and clip-bond construction prevent tombstoning and ensure wetting on both terminals.
What is the significance of the "KS" marking on the S1DRX body?
"KS" is the manufacturer-specific marking code for the S1DRX type, per Table 4 of the datasheet. It identifies the device as a 200 V, 1 A PN rectifier in SOD123W package and indicates cathode orientation-the "K" side corresponds to Pin 1 (cathode), which must be routed to the more negative potential in circuit layout.
