Product details
Overview
PD3S230H-7 from Diodes Incorporated is a 30V, 2.0A surface-mount Schottky barrier rectifier in PowerDI®323 package, featuring ultra-low forward voltage (0.55V @ 2.0A, +125°C), 30A non-repetitive surge capability, and AEC-Q101 qualification for automotive power conversion stages.
For engineers reviewing the PD3S230H-7 datasheet, PD3S230H-7 pinout, PD3S230H-7 application, or PD3S230H-7 equivalent, key selection criteria include forward voltage at high temperature, thermal resistance to soldering point (6°C/W), reverse leakage at rated VR (≤100µA @ 30V), and compatibility with FR-4 PCB layouts per AP02001.
Technical Context
This Schottky rectifier employs guard ring die construction to enhance transient robustness and suppress avalanche-induced failure during load dump events. Its low RθJS of 6°C/W enables efficient heat transfer to the PCB pad, supporting sustained 2.0A operation under ambient temperatures up to +125°C when mounted on 2 oz. copper FR-4.
The device delivers 0.50V typical VF at 2.0A and +25°C, rising to 0.55V at +125°C-critical for minimizing conduction loss in DC/DC output stages. Total capacitance remains stable at 40pF (VR = 10V, f = 1MHz), supporting fast switching in buck converter freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC bus or clamp circuit voltage rating. |
| IF(AV) | 2.0 A - Average forward current rating at TA = +25°C; derates to ~1.0A at +125°C per Fig.5. |
| VF @ 2.0A, +125°C | 0.55 V - Confirmed forward drop under worst-case thermal condition; directly reduces power loss in high-temp environments. |
| IFS M | 30 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush and fault-current handling in automotive 12V systems. |
| RθJS | 6 °C/W - Junction-to-soldering-point thermal resistance; enables direct thermal modeling from junction to PCB copper. |
| IR @ 30V, +25°C | ≤100 µA - Maximum reverse leakage at full rated voltage; ensures low standby power in always-on circuits. |
| CT @ 10V, 1MHz | 40 pF - Junction capacitance value; determines high-frequency switching losses and EMI behavior in SMPS freewheeling paths. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/52T | Same 30V/2A rating but SMA package (RθJA = 75°C/W); VF = 0.52V @ 2A, +25°C only. | Larger footprint and higher thermal resistance limits use in compact, high-ambient designs. | Select when legacy SMA footprint compatibility is required and board space permits. |
| SS23HE3_A/H | PowerDI™323 package, but VF = 0.57V @ 2A, +125°C and IR = 150µA @ 30V. | Higher leakage and slightly higher VF reduce efficiency in always-on or thermally constrained nodes. | Acceptable where cost sensitivity outweighs 5–10mW conduction loss increase per diode. |
Compared with SB230-E3/52T and SS23HE3_A/H, PD3S230H-7 delivers superior thermal performance (6°C/W vs. ≥75°C/W) and tighter leakage control (≤100µA), making it optimal for space-constrained automotive and industrial power rails where thermal margin and standby current are critical.

FAQ
What is the maximum operating temperature for PD3S230H-7?
The PD3S230H-7 has an operating junction temperature range of –65°C to +150°C. Its derating curve (Fig.5) shows usable average forward current drops to approximately 1.0A at +125°C ambient on FR-4 PCB, and full 2.0A is only sustainable below +70°C ambient without forced cooling.
Is PD3S230H-7 suitable for synchronous rectification?
No-PD3S230H-7 is a passive Schottky rectifier, not a synchronous rectifier IC. It lacks gate drive, control logic, or MOSFET integration. It serves as a freewheeling or OR-ing diode in conjunction with active controllers like the AP6320x or MP6908, but cannot replace them.
Does PD3S230H-7 require a heatsink?
No external heatsink is required. Its 6°C/W RθJS relies on thermal conduction through the copper pad per AP02001 layout. With proper 2 oz. copper pad (≥10mm²), it dissipates up to 0.8W continuously at +125°C ambient-sufficient for 2.0A at 0.55V drop.
How does the guard ring construction improve reliability?
The guard ring mitigates electric field crowding at the silicon periphery, suppressing premature edge breakdown during voltage transients. This extends time-to-failure under ISO 7637-2 Pulse 5a load-dump stress (120V/100ms), a key requirement for AEC-Q101 qualification.
