Product details
Overview
RB520CS3002LYL from Nexperia is a 200 mA, 30 V AEC-Q101-qualified Schottky barrier rectifier in DFN1006-2 (SOD882) package, featuring low 330–450 mV forward voltage at 10 mA and ≤0.5 µA reverse leakage at 10 V. It serves as a high-efficiency unidirectional current switch in space-constrained DC/DC converters and automotive power rails.
For engineers reviewing the RB520CS3002LYL datasheet, RB520CS3002LYL pinout, RB520CS3002LYL application, or RB520CS3002LYL equivalent, key selection criteria include its ultra-low VF for minimal conduction loss, AEC-Q101 qualification for under-hood use, thermal resistance of 145 K/W on ceramic PCB, and cathode-marked DFN1006-2 footprint compatibility with automated SMT assembly.
Technical Context
This MEGA Schottky diode uses planar junction technology with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its low barrier height enables sub-450 mV forward voltage while maintaining <0.5 µA IR at 10 V - critical for battery-powered systems where leakage directly impacts standby life.
The device operates up to 150 °C junction temperature and delivers 200 mA average forward current under square-wave conditions (δ = 0.5, f = 20 kHz) on FR4 PCB with 1 cm² cathode pad. Thermal performance varies significantly by board material: Rth(j-a) is 395 K/W on standard FR4 but improves to 145 K/W on Al₂O₃ ceramic - enabling higher power density in thermally demanding automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 200 mA average forward current - supports continuous operation in low-power SMPS output stages without forced cooling |
| VR | 30 V reverse voltage - suitable for 24 V automotive systems with transient margin |
| VF @ 10 mA | 330–450 mV - reduces conduction loss by >40% vs. standard silicon diodes in 3.3 V/5 V buck converters |
| IR @ 10 V | 0.14–0.5 µA - ensures <1 µW reverse power dissipation at 10 V bias, critical for battery backup circuits |
| Cd @ 1 V | 10 pF - minimizes switching noise and EMI in high-frequency (>1 MHz) DC/DC topologies |
| Rth(j-sp) | 70 K/W - enables direct thermal coupling to PCB copper via cathode solder point for improved heat extraction |
| AEC-Q101 | Qualified - validated for automotive applications including engine control units and body electronics |
Pinout & Package
DFN1006-2 (SOD882) is a leadless, ultra-small surface-mount plastic package measuring 1.02 × 0.62 × 0.30 mm, with exposed cathode pad for thermal and electrical connection. The marking bar on top indicates cathode polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; electrically and thermally connected to exposed bottom pad - must be routed to large copper area for thermal management |
| 2 (A) | Anode | Current entry terminal; smaller top-side metallization - designed for minimal trace inductance in high-speed switching paths |
Key Features
| Feature | Design Value |
|---|---|
| MEGA Schottky architecture | Planar junction with integrated guard ring - prevents premature edge breakdown during voltage transients in automotive load-dump events |
| Ultra-low VF | 330 mV typical at 10 mA - cuts forward power loss by ~65% versus comparable 1N5819-type Schottkys, extending battery runtime in portable devices |
| Low IR | 0.14 µA typical at 10 V - eliminates measurable leakage impact on Li-ion battery self-discharge in always-on sensor nodes |
| AEC-Q101 qualification | Stress-tested per automotive discrete semiconductor standard - validated for temperature cycling, HTRB, and ESD (HBM ≥2 kV) required in vehicle ECUs |
| DFN1006-2 footprint | 0.62 mm width - enables placement in tight spaces such as USB-C PD adapter secondary side or LED driver IC bypass paths |
Applications
| Automotive Body Control Module | USB-C Power Delivery Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S30T2R | Same die, but in SOD-523 package (1.2 × 0.8 mm) - 2× larger footprint, 250 mW Ptot rating vs. 315 mW in DFN1006-2 | Less suitable for ultra-dense layouts; lower thermal performance due to higher Rth(j-a) ≈ 450 K/W on FR4 | Select when legacy SOD-523 reflow profile is fixed and board real estate allows 30% larger area |
| PMEG2005AEA | 20 V VR, 500 mA IF(AV), 310 mV VF @ 10 mA - higher current rating but lower voltage margin | Not rated for 24 V automotive systems; lacks AEC-Q101 qualification | Prefer only in non-automotive 3.3 V/5 V consumer power rails where 20 V VR suffices and cost-per-amp is prioritized |
Compared with RB520S30T2R, RB520CS3002LYL offers superior thermal performance and space savings; versus PMEG2005AEA, it trades current headroom for automotive-grade reliability and 30 V system compatibility - making it optimal for safety-critical, thermally constrained 12–24 V embedded power designs.

FAQ
Is RB520CS3002LYL compatible with lead-free reflow profiles?
Yes. The DFN1006-2 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C for 30 seconds. Recommended profile includes ramp rate ≤3 °C/s, preheat 150–200 °C for 60–120 s, and time above liquidus (217 °C) of 60–90 s - matching standard Type 3 solder paste specifications.
What is the maximum allowable solder point temperature during rework?
The absolute maximum solder point temperature is 260 °C for ≤10 seconds per joint, as defined by Nexperia's rework guidelines. Exceeding this risks delamination of the die attach or intermetallic formation at the cathode pad interface, which degrades thermal resistance and long-term reliability.
Does the cathode marking bar indicate polarity during automated optical inspection (AOI)?
Yes. The laser-marked bar on the top surface aligns with Pin 1 (cathode) and is detectable by standard AOI systems using contrast-based algorithms. Its position relative to the DFN1006-2 outline (0.55 mm from left edge, centered vertically) provides unambiguous orientation verification prior to reflow.
How does thermal resistance change when mounted on 2-layer vs. 4-layer PCBs?
Rth(j-a) improves from 395 K/W (FR4, single-sided, 1 cm² pad) to ~280 K/W on 2-layer boards with internal ground plane, and further to ~220 K/W on 4-layer boards with dedicated thermal vias under the cathode pad - verified per Nexperia's thermal characterization data in Table 6.
