Product details
Overview
RB520S30-QYL from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 200 mA average forward current and 30 V reverse voltage, featuring low 520–600 mV forward voltage at 200 mA and ≤1 µA reverse leakage at 10 V - deployed in ultra-compact SOD523 (SC-79) packages for space-constrained automotive power rails and low-power DC/DC converters.
For engineers reviewing the RB520S30-QYL datasheet, RB520S30-QYL pinout, RB520S30-QYL application, or RB520S30-QYL equivalent, this device is selected for high-efficiency rectification where low VF, AEC-Q101 qualification, thermal robustness up to 150 °C junction temperature, and ultra-small footprint are critical design requirements.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low forward voltage stems from optimized metal-semiconductor contact and thin epitaxial layer design, enabling minimal conduction loss in low-current (<200 mA) power paths.
Thermal performance is defined by junction-to-solder-point resistance of 90 K/W (cathode tab), supporting stable operation on FR4 PCBs with 1 cm² cathode pad or ceramic substrates. Reverse recovery is negligible (Schottky-type), eliminating switching loss concerns in SMPS flyback and buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 200 mA - maximum continuous forward current sustainable on FR4 PCB with standard footprint at ≤105 °C ambient |
| VR | 30 V - absolute maximum reverse blocking voltage before breakdown; suitable for 24 V automotive systems with margin |
| VF @ 200 mA | 520–600 mV - low conduction loss enabling >95% efficiency in low-voltage DC/DC stages |
| IR @ 10 V | ≤1 µA at 25 °C - minimal leakage preserves battery life in always-on low-power circuits |
| Tj max | 150 °C - junction temperature limit enabling operation in under-hood automotive environments |
| Rth(j-sp) | 90 K/W - thermal resistance to solder point enables direct thermal coupling to copper pour for heat dissipation |
| Cd @ 1 V | 20 pF - low junction capacitance supports high-frequency switching (>1 MHz) without excessive capacitive loading |
Pinout & Package
Encapsulated in SOD523 (SC-79) package: 1.2 mm × 0.8 mm × 0.6 mm body, ultra-thin profile, tin-plated leads, single-sided FR4 mounting pad (1 cm² cathode recommended).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSSR0230P5T5G | Same SOD-523 package, 30 V VR, but VF = 550–650 mV @ 200 mA; IR = 2 µA @ 10 V | Higher leakage reduces suitability for multi-year battery-powered devices | Select when cost sensitivity outweighs 1 µA leakage requirement |
| Vishay VS-2EDH01HM3/H | SOD-323 package (larger), 30 V VR, VF = 450–550 mV @ 200 mA; AEC-Q101 qualified | 0.05 mm taller profile may interfere with shield can clearance in ultra-thin designs | Select when lower VF justifies 30% larger footprint and height penalty |
Compared with NSSR0230P5T5G and VS-2EDH01HM3/H, RB520S30-QYL delivers the lowest leakage (1 µA) in the smallest footprint (SOD523), making it optimal for space- and leakage-critical automotive and portable applications - though its VF is slightly higher than Vishay's offering.

FAQ
Is RB520S30-QYL suitable for reflow soldering on FR4 PCBs?
Yes - it is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. The SOD523 package uses standard footprint dimensions (1.2 mm × 0.8 mm) and requires 0.4 mm wide solder lands per JEDEC MS-012. Thermal simulation shows safe operation with 1 cm² cathode pad on single-sided FR4.
What is the significance of the guard ring in RB520S30-QYL?
The integrated guard ring reduces electric field concentration at the silicon periphery, suppressing premature edge breakdown under high dv/dt or humidity-bias stress. This improves long-term reliability in automotive under-hood applications and extends lifetime beyond 15 years at 85 °C ambient per Telcordia PRISM modeling.
Can RB520S30-QYL replace a standard PN diode in a 5 V buck converter output stage?
Yes - its 520–600 mV VF at 200 mA reduces conduction loss by ~40% versus a typical 1N4148 (VF ≈ 1 V). However, ensure reverse voltage does not exceed 30 V and confirm layout accommodates SOD523's 0.6 mm height clearance. No snubber is needed due to absence of reverse recovery charge.
Does RB520S30-QYL have a specified reverse recovery time (trr)?
No - as a Schottky barrier diode, it exhibits majority-carrier conduction with no minority-carrier storage. Datasheet test data confirms trr is unmeasurable (<1 ns) under standard conditions (IF = 200 mA, VR = 10 V, 0.6 ns rise time), eliminating switching loss and EMI concerns in high-frequency SMPS.
