Product details
Overview
RB520CS30L,315 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-current, high-efficiency rectification in space-constrained PCBs. It delivers 100 mA average forward current, 30 V reverse voltage rating, and ultra-low 330 mV typical forward voltage at 10 mA - enabling high-efficiency DC-DC conversion in automotive and portable power rails.
For engineers reviewing the RB520CS30L,315 datasheet, RB520CS30L,315 pinout, RB520CS30L,315 application, or RB520CS30L,315 equivalent, key selection criteria include its AEC-Q101 qualification, SOD882 leadless package footprint, sub-0.5 μA reverse leakage at 10 V, and thermal resistance of 220 K/W on FR4 with cathode pad - critical for thermally sensitive low-power designs.
Technical Context
This MEGA Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface engineering, not barrier height reduction alone - preserving low IR while minimizing conduction loss.
Thermal performance is defined by mounting-dependent Rth(j-a): 395 K/W (free air), 220 K/W (FR4, 1 cm² cathode pad), or 145 K/W (Al₂O₃ ceramic). Junction temperature must be limited to 150 °C, and reflow soldering is the only qualified assembly method per Nexperia's process specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 100 mA - maximum continuous forward current at ≤135 °C ambient or ≤145 °C solder point, enabling stable operation in compact power rails |
| VR | 30 V - peak repetitive reverse voltage; suitable for 24 V automotive systems with margin against load-dump transients |
| VF @ 10 mA | 330–450 mV - low conduction loss improves efficiency in battery-powered DC-DC stages and reverse polarity protection |
| IR @ 10 V | 0.14–0.5 μA - minimal leakage preserves battery life in always-on circuits and low-power sensor nodes |
| Cd @ 1 V | 10 pF - low junction capacitance supports fast switching in high-frequency SMPS (≥1 MHz) without excessive ringing |
| Rth(j-sp) | 70 K/W - thermal resistance from junction to cathode solder point, critical for thermal design when using copper pour |
| AEC-Q101 | Qualified - validated for automotive applications including engine control modules and body electronics |
Pinout & Package
Encapsulated in a leadless SOD882 plastic package (1.0 × 0.6 × 0.5 mm), the RB520CS30L,315 uses a two-terminal surface-mount configuration with cathode identified by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Output terminal for forward conduction; requires dedicated thermal pad (1 cm² minimum) on PCB for rated IF(AV) |
| 2 | Anode | Input terminal; connects to source side of rectification path; no thermal pad requirement |
Key Features
| Feature | Design Value |
|---|---|
| MEGA Schottky architecture | Planar die with integrated guard ring - prevents premature edge breakdown under voltage stress, improving long-term reliability in automotive environments |
| Ultra-low VF | 330 mV typ. at 10 mA - reduces power loss by >40% vs. standard Schottkys in 3.3 V/5 V rail clamping and reverse protection |
| SOD882 package | 1.0 × 0.6 mm footprint - saves >60% board area vs. SOD323, enabling dense power management in wearables and ECUs |
| AEC-Q101 qualification | Stress-tested per automotive discrete standard - ensures robustness across −40 °C to +125 °C operating range with thermal cycling and HTRB validation |
| Reflow-only assembly | Validated for JEDEC J-STD-020D reflow profile - eliminates risk of voiding or delamination during automated PCB assembly |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Clamp |
|---|---|
|
Use Scenario: Reverse polarity protection on 12 V supply input to microcontroller-based door module. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection. Use Value: 0.45 V max VF limits voltage drop to <1.5% at 100 mA, preserving brown-out margin for 5 V LDO regulator input. |
Use Scenario: Output clamp in 5 V/3 A USB-C PD sink circuit to prevent backfeed into upstream controller during hot-plug. IC Role / Device Role / Timing Role: Fast-recovery Schottky rectifier isolating VBUS path during state transitions. Use Value: 10 pF junction capacitance minimizes signal integrity impact on CC line communication timing. |
| Industrial Sensor Node Power Rail | Low-Power IoT Wireless Transceiver |
|
Use Scenario: Input rectification for energy-harvesting circuit powered by piezoelectric transducer (peak 50 mA, 20 V). IC Role / Device Role / Timing Role: AC-to-DC converter front-end with minimal quiescent loss. Use Value: 0.14 μA typ. IR at 10 V extends battery-less operation time by >200 hours per μJ harvested. |
Use Scenario: Reverse current isolation between coin-cell battery and buck-boost PMIC in BLE beacon. IC Role / Device Role / Timing Role: Leakage-suppressing diode in battery backup path. Use Value: Sub-0.5 μA IR prevents >1.2 μA parasitic drain - extending shelf life beyond 5 years at 25 °C. |
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); VF identical, but Rth(j-a) = 420 K/W on FR4 | Less thermal margin in high-density layouts; unsuitable for sustained 100 mA without copper pour | Select when board area allows larger footprint and thermal constraints are relaxed |
| NSR0230HT1G | 0.2 A IF(AV), 30 V VR, VF = 370 mV @ 10 mA; 12 pF Cd; AEC-Q101 qualified; SOD-923 (1.0 × 0.6 mm) | Higher current rating enables shared use across multiple rails; slightly higher VF increases conduction loss by ~12% | Choose when future-proofing for 150–200 mA loads or multi-rail consolidation is required |
Compared with RB520S30T2R, the RB520CS30L,315 offers superior thermal performance on FR4 via its optimized SOD882 cathode pad layout; versus NSR0230HT1G, it trades 200 mA capability for lower VF and tighter leakage - favoring ultra-low-power over headroom.

FAQ
Is RB520CS30L,315 suitable for reflow soldering only?
Yes - Nexperia explicitly qualifies RB520CS30L,315 for reflow soldering per JEDEC J-STD-020D only. Wave soldering, hand soldering, or infrared methods are not validated and may cause delamination or interfacial failure due to thermal mismatch in the SOD882 leadless structure.
What is the maximum allowable junction temperature during operation?
The absolute maximum junction temperature is 150 °C. Operation above this limit risks irreversible degradation of the Schottky barrier. Derating curves in the datasheet show that at 100 mA IF(AV), ambient temperature must remain ≤135 °C on FR4 with 1 cm² cathode pad to maintain Tj ≤150 °C.
How does the guard ring affect reliability in automotive applications?
The integrated guard ring mitigates electric field crowding at the die edge, raising the effective breakdown voltage under mechanical stress (e.g., thermal cycling, vibration). This directly improves long-term stability in AEC-Q101 tests like HTRB and TC1000, reducing infant mortality in BCM and lighting modules.
Can RB520CS30L,315 replace RB520S30 in existing designs?
No - RB520S30 uses SOD-323 packaging (1.7 × 1.25 mm) with different thermal pad geometry and solder land pattern. While electrical specs overlap, the SOD882 footprint of RB520CS30L,315 requires PCB redesign; direct replacement would cause solder joint voiding and thermal derating.
