Product details
Overview
PD3S130L-7 from Diodes Incorporated is a 30 V, 1.0 A surface-mount Schottky barrier rectifier in PowerDI®323 package, featuring ultra-low forward voltage (0.33 V at 0.7 A), high surge capability (22 A IFSM), and AEC-Q101 qualification for automotive power rail clamping and reverse polarity protection.
For engineers reviewing the PD3S130L-7 datasheet, PD3S130L-7 pinout, PD3S130L-7 application, or PD3S130L-7 equivalent, key selection criteria include VF vs. IF trade-off, thermal resistance (RθJS = 6.0 °C/W), junction temperature limits (–65 to +125 °C), and RoHS-compliant matte tin terminations on copper leadframe.
Technical Context
This Schottky diode uses guard ring die construction to suppress transient-induced avalanche breakdown and sustain reliable operation under repetitive 30 V reverse bias. Its low CT (40 pF at 10 V) and fast switching enable use in high-frequency DC/DC output rectification and EMI-sensitive automotive subsystems.
Thermal performance is defined by two distinct paths: junction-to-soldering-point (RθJS = 6.0 °C/W) for PCB-level thermal design, and junction-to-ambient (RθJA = 177 °C/W) under standard FR-4 layout per AP02001. Derating curves confirm full 1.0 A rating up to +75 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum non-repetitive reverse voltage before breakdown; sets safe operating limit for 24 V automotive systems with load dump margin. |
| IF(AV) | 1.0 A - Average forward current rating at TA = 25 °C; derates linearly to ~0.6 A at +100 °C per Fig. 5. |
| VF | 0.33 V @ 0.7 A - Low conduction loss enables >95% efficiency in 5–12 V buck converter outputs. |
| IFSM | 22 A - Peak non-repetitive surge current handling for cold-crank and jump-start transients. |
| RθJS | 6.0 °C/W - Junction-to-soldering-point thermal resistance; enables direct thermal coupling to copper pour for compact layouts. |
| CT | 40 pF @ 10 V - Low junction capacitance minimizes switching noise and improves EMI performance in SMPS. |
Pinout & Package
Package: PowerDI®323 - ultra-compact 2-pin surface-mount plastic package (2.5 × 1.9 × 0.13 mm), UL 94V-0 rated, moisture sensitivity Level 1, cathode-banded polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to input/source side; requires minimum 1.4 mm pad length for solder joint reliability per AP02001. |
| Cathode (banded) | Current exit terminal | Connected to ground/load; cathode band identifies polarity during automated optical inspection (AOI) and placement. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge leakage and prevents premature avalanche during voltage transients in automotive 12 V rails. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and UHAST - suitable for engine control and body electronics. |
| RoHS-compliant matte tin finish | Lead-free termination compatible with Pb-free reflow profiles; solderable per MIL-STD-202, Method 208. |
| Green molding compound | Halogen-free (no Br, Sb) encapsulant meeting IEC 61249-2-21; reduces toxic gas emission during board assembly or fire event. |
Applications
| Automotive Reverse Polarity Protection | DC/DC Converter Output Rectification |
|---|---|
Use Scenario: Protects infotainment head units and ADAS cameras from damage when battery leads are accidentally reversed during service. IC Role / Device Role / Timing Role: Unidirectional current gate placed between battery input and downstream LDO/PMIC; conducts only when anode > cathode by ≥0.25 V. Use Value: 0.33 V VF at 0.7 A limits power loss to <230 mW, avoiding thermal shutdown in sealed enclosures. | Use Scenario: Used in secondary-side synchronous rectification of 5 V/3 A buck converters powering microcontrollers and sensors. IC Role / Device Role / Timing Role: Freewheeling path during high-side FET off-time; recirculates inductor current with minimal voltage drop. Use Value: 40 pF junction capacitance reduces ringing and EMI emissions compared to higher-Ct alternatives like 1N5819. |
| USB Power Input Clamping | Industrial Sensor Signal Conditioning |
Use Scenario: Clamp circuit on USB Type-C VBUS line to prevent overvoltage from faulty chargers or hot-plug transients. IC Role / Device Role / Timing Role: Standby shunt element biased below 30 V; conducts only during >30 V excursions to divert surge energy. Use Value: 22 A IFSM withstands 10/1000 µs surges per IEC 61000-4-5 without degradation. | Use Scenario: Isolates analog sensor supply rails (e.g., 3.3 V pressure transducers) from shared 5 V system bus during brown-out events. IC Role / Device Role / Timing Role: Back-to-back blocking diode in dual-rail isolation network; prevents reverse current flow from 5 V to 3.3 V domain. Use Value: –65 to +125 °C operating range ensures stable leakage (<0.37 µA @ 5 V) across industrial temperature cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB130-E3/54 (Vishay) | Same 30 V / 1.0 A rating but TO-277 package (larger footprint, RθJA = 120 °C/W). | Less suitable for space-constrained automotive modules; better for manual repair due to larger pads. | Select if board rework accessibility outweighs size constraints. |
| SS13 (ON Semiconductor) | PowerDI™123 package (2.7 × 1.7 × 0.9 mm); VF = 0.45 V @ 1.0 A - 36% higher conduction loss. | Acceptable for lower-current sensor rails but not for 1 A continuous power paths. | Choose only where thermal budget allows higher VF and footprint is less critical than cost. |
Compared with SB130-E3/54 and SS13, PD3S130L-7 delivers the lowest thermal resistance (RθJS = 6.0 °C/W) and best VF performance in the smallest footprint, making it optimal for high-density automotive PCBs requiring AEC-Q101 compliance and minimal power loss.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PD3S130L-7 has a specified operating junction temperature range of –65 °C to +125 °C. Continuous operation at TJ = +125 °C is permitted only when thermal design ensures steady-state power dissipation stays within derated limits - e.g., ≤0.6 A at +100 °C ambient per Figure 5.
Does this part support lead-free reflow soldering?
Yes. The PD3S130L-7 features matte tin annealed over copper leadframe, qualified for Pb-free reflow profiles per J-STD-020D Level 1 moisture sensitivity. It meets MIL-STD-202, Method 208 for solderability and is RoHS compliant per EU Directive 2002/95/EC.
How does the guard ring construction improve reliability?
The guard ring die structure surrounds the active junction to suppress electric field crowding at chip edges, preventing localized avalanche breakdown during transient overvoltage events. This extends lifetime under repetitive 30 V reverse bias and improves robustness in automotive load-dump conditions.
Can PD3S130L-7 replace 1N5819 in existing designs?
Yes, with caveats: both are 30 V/1 A Schottky diodes, but PD3S130L-7 offers lower VF (0.33 V vs. 0.475 V @ 0.7 A) and smaller PowerDI®323 footprint vs. DO-27. Layout redesign is required; thermal performance improves due to lower RθJS (6.0 vs. ~20 °C/W).
