Product details
Overview
PD3S0230-7 from Diodes Incorporated is a surface-mount Schottky barrier diode in POWERDI®323 package, rated for 30 V reverse voltage, 200 mA continuous forward current, and 0.485 V max forward voltage at 100 mA. It serves as a polarity protection or recirculating diode in low-voltage DC power rails of portable electronics and USB-powered devices.
For engineers reviewing the PD3S0230-7 datasheet, PD3S0230-7 pinout, PD3S0230-7 application, or PD3S0230-7 equivalent, key selection criteria include ultra-low VF at low IF, fast 5.0 ns reverse recovery time, 2.0 µA max leakage at 25 V, thermal resistance of 242 °C/W, and compatibility with automated SMT assembly on FR-4 boards.
Technical Context
This Schottky diode uses a planar epitaxial structure with PN junction guard ring to suppress ESD and transient overstress. Its low barrier height enables sub-0.5 V forward drop at 100 mA while maintaining 30 V blocking capability.
Designed for high-efficiency, space-constrained DC/DC output stages and battery protection circuits, it operates across –65 °C to +125 °C ambient and delivers stable performance up to 100 mA without thermal runaway under typical PCB pad layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 30 V - Maximum DC blocking voltage before breakdown; sets upper limit for input rail protection in 3.3 V/5 V systems. |
| IF Continuous (mA) | 200 mA - Sustained forward current rating; supports load currents in USB peripherals and sensor nodes. |
| VF Max @ 100 mA (V) | 0.485 V - Low conduction loss ensures >95% efficiency in 3.3 V supply paths with <16 mW dissipation. |
| IR Max @ 25 V (µA) | 2.0 µA - Minimal leakage preserves battery life in always-on standby circuits. |
| trr (ns) | 5.0 ns - Fast switching enables use in 1–10 MHz flyback snubbers and synchronous rectifier auxiliary paths. |
| RθJA (°C/W) | 242 - Thermal resistance on standard FR-4; requires minimal copper area for self-heating <10 °C at 100 mA. |
| Package | POWERDI®323 - 2.5 × 1.9 mm footprint; compatible with 0603 reflow profiles and high-density routing. |
Pinout & Package
POWERDI®323 is a 2-terminal surface-mount package with cathode band marking. Terminals are matte tin–annealed copper leadframe, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to positive supply or switch node; accepts up to 600 mA non-repetitive surge. |
| Cathode (banded) | Forward current exit / reverse blocking terminal | Connected to load ground or return path; blocks 30 V reverse bias with <2 µA leakage. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF ≤ 0.485 V @ 100 mA reduces power loss by >40% vs. standard silicon diodes in 3.3 V rails. |
| Fast switching speed | trr ≤ 5.0 ns minimizes switching loss in high-frequency DC/DC feedback loops and clamp circuits. |
| PN junction guard ring | ESD protection per IEC 61000-4-2 Level 4 (±15 kV air) and robust transient immunity in automotive load-dump environments. |
| Ultra-small surface-mount package | POWERDI®323 (2.5 × 1.9 mm) saves >50% board area vs. SOD-123 while maintaining thermal performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Higher VF (0.52 V @ 100 mA); SOT-23 package (larger footprint, higher RθJA = 300 °C/W) | Less suitable for ultra-thin wearables due to taller profile and lower thermal efficiency | Prefer when existing SOT-23 layout reuse is required and 0.035 V higher VF is acceptable |
| NSR0230HT1G | Same VF spec (0.485 V), but 0.7 mm wider package (2.5 × 2.6 mm); 3.0 µA IR @ 25 V | Marginally higher leakage may impact multi-year battery life in low-power IoT nodes | Choose if board space allows larger footprint and leakage sensitivity is low |
Compared with SBAT54LT1G and NSR0230HT1G, PD3S0230-7 delivers best-in-class thermal performance (242 °C/W) and lowest leakage (2.0 µA) in the smallest 2.5 × 1.9 mm footprint-critical for miniaturized USB-C accessories and medical patch monitors.

FAQ
What is the maximum junction temperature for PD3S0230-7?
The absolute maximum junction temperature is +125 °C, with continuous operation supported from –65 °C to +125 °C ambient. Derating begins above +25 °C ambient per Figure 4 in DS30722 Rev.10, where usable IF drops linearly to zero at +125 °C on standard FR-4.
Is PD3S0230-7 suitable for automotive applications?
PD3S0230-7 meets AEC-Q200 stress test requirements for passive components and features a PN guard ring for ESD robustness. While not AEC-Q101 qualified as a discrete diode, it is used in non-safety-critical automotive infotainment and body-control modules with proper system-level validation.
Does PD3S0230-7 have a specified moisture sensitivity level?
Yes, PD3S0230-7 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/85% RH and is safe for standard SMT reflow without baking prior to assembly.
How does the POWERDI®323 package compare to SOD-123 in thermal performance?
POWERDI®323 achieves RθJA = 242 °C/W on FR-4, outperforming typical SOD-123 (RθJA ≈ 320–350 °C/W) due to its exposed copper leadframe and optimized thermal pad layout, enabling 25% higher continuous current in same board area.
