Product details
Overview
PD3S230HQ-7 from Diodes Incorporated is a 30V, 2.0A surface-mount Schottky barrier rectifier in PowerDI®323 package, featuring 0.60V max forward voltage at 2.0A and 0.1mA max reverse leakage at 30V. It is AEC-Q101 qualified for automotive polarity protection, recirculation, and switching applications with guard ring die construction and high surge capability (30A IFSM).
For engineers reviewing the PD3S230HQ-7 datasheet, PD3S230HQ-7 pinout, PD3S230HQ-7 application, or PD3S230HQ-7 equivalent, key selection criteria include low VF for efficiency-critical 12V automotive rails, thermal resistance (RθJA = 128°C/W on polyimide PCB), AEC-Q101 qualification, and PowerDI®323 footprint compatibility with space-constrained ECU and body control modules.
Technical Context
This Schottky rectifier uses platinum-silicide or similar low-barrier metal-semiconductor junction to achieve fast switching (no minority-carrier storage) and low forward conduction loss. Its guard ring die structure enhances transient voltage immunity-critical for load dump and inductive kickback suppression in 12V automotive systems.
Thermal performance is defined by two RθJA values: 177°C/W on FR-4 and 128°C/W on polyimide PCBs, reflecting layout-dependent dissipation limits. The 6°C/W RθJS enables direct junction-to-solder-point thermal modeling for board-level reliability analysis under continuous 2.0A operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (VRRM) | 30 V - Maximum repetitive reverse voltage; defines safe blocking capability in 12V automotive circuits with ±25% supply tolerance and load dump transients. |
| IF(AV) | 2.0 A - Average forward current rating; supports continuous DC output in auxiliary power supplies and LED drivers without forced air cooling. |
| VF max | 0.60 V @ 2.0A, +25°C - Low conduction loss reduces power dissipation to ≤1.2W at full load, easing thermal design in sealed enclosures. |
| IR max | 100 µA @ 30V, +25°C - Tight leakage spec ensures minimal standby current drain in always-on vehicle modules. |
| IFSM | 30 A @ 8.3ms - Withstands motor stall or solenoid de-energization surges without degradation. |
| RθJA | 128 °C/W - Achievable on polyimide PCB with recommended pad layout; allows ~1.1W max power dissipation at +85°C ambient. |
Pinout & Package
Package: PowerDI®323 - ultra-small surface-mount plastic package (2.5 × 1.9 × 0.9 mm), RoHS-compliant, halogen-free, with matte tin-plated copper leadframe and cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current input | Connected to source-side of protected circuit; accepts up to 2.0A DC with <0.6V drop. |
| Cathode | Forward current output / Reverse blocking terminal | Connected to load ground or return path; blocks up to 30V reverse while leaking <100µA at rated VR. |
Key Features
| Feature | Design Value |
|---|---|

| PowerDI®323 footprint | 0.006g mass and 2.5mm × 1.9mm area reduce board space by >40% vs. SMA, enabling dense placement in ADAS sensor modules. |
| Lead-free & "Green" compliance | Meets RoHS 2 and halogen/antimony thresholds (<900ppm Br/Cl, <1000ppm Sb), satisfying EU automotive material declarations. |
Applications
| Body Control Module (BCM) Polarity Protection | Engine Control Unit (ECU) Recirculation Diode |
|---|---|
Use Scenario: Prevents damage from reverse battery connection in 12V-powered BCMs handling door locks, lighting, and HVAC controls. IC Role / Device Role / Timing Role: Unidirectional current gate placed between battery input and main DC-DC converter input. Use Value: 0.60V VF minimizes voltage drop across protection path, preserving ≥11.4V input to downstream regulators during cold-crank conditions. | Use Scenario: Suppresses inductive kickback from fuel injector solenoids during PWM switching in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Freewheeling path for coil current decay; must respond within nanoseconds to prevent MOSFET drain overvoltage. Use Value: Schottky architecture enables <10ns recovery, limiting VDS spikes to <35V and eliminating need for snubber networks. |
| ADAS Camera Power Supply | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Provides clean, low-noise 5V/3.3V bias rail for CMOS image sensors and ISP processors in rear-view and surround-view cameras. IC Role / Device Role / Timing Role: Output rectifier in secondary-side synchronous buck or flyback converter. Use Value: 40pF CT at 10V minimizes high-frequency coupling into analog sensor paths, reducing image noise and EMI emissions. | Use Scenario: Clamps back-EMF during regenerative braking and motor phase commutation in 12V EPS H-bridge drivers. IC Role / Device Role / Timing Role: Bidirectional clamp diode integrated into half-bridge power stage layout. Use Value: 30A IFSM rating handles repeated 25A motor current reversals without thermal runaway, extending MOSFET lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/54 (Vishay) | Same 30V/2A rating but SMA package (larger footprint, higher RθJA ≈ 180°C/W); VF = 0.55V typical at 2A. | Not AEC-Q101 qualified; intended for industrial/commercial use only. | Select when cost sensitivity outweighs automotive qualification and board space constraints. |
| SS23HE3/52T (Vishay) | PowerDI®323 package, AEC-Q101 qualified, but VF = 0.52V typ at 2A and IR = 200µA max at 30V. | Higher leakage may increase standby current in always-on modules like telematics units. | Select when lower VF is prioritized and leakage budget allows ≥200µA at 30V. |
Compared with SB230-E3/54 and SS23HE3/52T, PD3S230HQ-7 uniquely balances AEC-Q101 compliance, PowerDI®323 miniaturization, and tight 100µA leakage-making it optimal for space- and reliability-constrained automotive modules where both thermal density and quiescent current matter.

FAQ
What is the maximum junction temperature for continuous operation?
The PD3S230HQ-7 has an operating junction temperature range of −55°C to +150°C. For continuous 2.0A DC operation, thermal design must ensure TJ does not exceed +150°C-achievable with ≤128°C/W RθJA on polyimide PCB and ≤+85°C ambient, per Fig. 5 derating curve.
Is the PowerDI®323 package compatible with standard reflow profiles?
Yes-the PowerDI®323 package is rated for moisture sensitivity level 1 (J-STD-020) and supports standard Pb-free reflow profiles. Its matte tin finish ensures reliable solderability per MIL-STD-202, Method 208, with peak temperatures up to 260°C.
How does the guard ring die construction improve reliability?
The guard ring structure surrounds the active junction to suppress edge breakdown under high dv/dt or ESD stress. In automotive environments, this increases immunity to load dump transients (ISO 7637-2 Pulse 5a) and improves long-term stability of reverse leakage current over 15-year vehicle lifetimes.
Can PD3S230HQ-7 replace SMA-package Schottkys in existing designs?
Direct replacement requires PCB pad redesign due to PowerDI®323's smaller 2.5mm × 1.9mm outline versus SMA's 4.3mm × 2.6mm. Thermal performance improves (lower RθJA), but layout validation is required to confirm solder joint integrity and current-carrying capacity of new traces.
