Product details
Overview
PD3S130LQ-7 from Diodes Incorporated is a 30 V, 1.0 A surface-mount Schottky barrier rectifier in PowerDI®323 package, optimized for automotive polarity protection and flyback recirculation. It delivers low forward voltage (0.42 V max at 1.0 A), ultra-low leakage (1.5 mA max at 30 V), and AEC-Q101 qualification for under-hood reliability.
For engineers reviewing the PD3S130LQ-7 datasheet, PD3S130LQ-7 pinout, PD3S130LQ-7 application, or PD3S130LQ-7 equivalent, key selection criteria include reverse voltage rating, surge current capability (22 A IFSM), thermal resistance (6.0 °C/W junction-to-solder point), and RoHS-compliant green packaging with matte tin terminations.
Technical Context
This Schottky diode employs guard ring die construction to enhance transient immunity and supports high-reliability automotive operation across –65 °C to +125 °C junction temperature range. Its low RθJS (6.0 °C/W) enables efficient heat transfer to PCB copper, critical for space-constrained engine control modules.
The device exhibits soft reverse recovery and minimal capacitance (40 pF at 10 V), making it suitable for high-frequency switching topologies where EMI and switching loss must be minimized-especially in DC/DC converters and load-dump protected power rails.

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, 3.5 × 2.5 mm); VF = 0.5 V @ 1 A | Less suitable for ultra-dense layouts; higher thermal resistance (RθJA ≈ 190 °C/W) | Prefer when legacy TO-277 footprint compatibility is required over size or efficiency |
| SS13 (ON Semiconductor) | PowerDI323 package, but only AEC-Q200 qualified (not Q101); VF = 0.45 V @ 1 A; IR = 2.0 mA @ 30 V | Limited to non-safety-critical cabin applications due to lower qualification level | Select only for cost-sensitive interior modules where full AEC-Q101 is not mandated |
Compared with SB130-E3/54 and SS13, PD3S130LQ-7 uniquely combines AEC-Q101 qualification, PowerDI323 miniaturization, and lowest VF (0.42 V) in its class-making it optimal for next-gen ECU and ADAS power stages demanding size, reliability, and efficiency.

FAQ
What is the maximum junction temperature for continuous operation?
The PD3S130LQ-7 has an operating junction temperature range of –65 °C to +125 °C. For reliable long-term operation at full 1.0 A average forward current, ambient temperature must be derated per Figure 5 in the datasheet-e.g., maximum TA drops to ~75 °C on standard FR-4 with 2 oz copper.
Is the PD3S130LQ-7 suitable for use in DC/DC converter output rectification?
Yes-it is commonly used in synchronous and asynchronous buck converter outputs due to its low VF (0.42 V max), fast switching, and low capacitance (40 pF). Its 30 V VR rating supports 12 V input systems, and AEC-Q101 qualification ensures stability in automotive converter designs.
Does the PowerDI323 package require special reflow profile considerations?
No special profile is needed beyond standard lead-free reflow. The device is rated for moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30 °C/60% RH and processed with JEDEC J-STD-020-compliant peak temperatures up to 260 °C.
How does the guard ring construction improve real-world performance?
The guard ring die structure suppresses edge breakdown and enhances transient voltage immunity-particularly against ISO 7637-2 pulse 1 and pulse 5a load-dump events. This reduces need for external clamping components and improves field failure rates in harsh automotive environments.
