Product details
Overview
PD3S230LQ-7 from Diodes Incorporated is a 30V, 2.0A surface-mount Schottky barrier rectifier in the POWERDI®323 package, featuring ultra-low forward voltage (0.36V at 2.0A/125°C), 30A non-repetitive surge capability, and AEC-Q101 qualification for automotive power rail clamping and DC-DC converter output rectification.
For engineers reviewing the PD3S230LQ-7 datasheet, PD3S230LQ-7 pinout, PD3S230LQ-7 application, or PD3S230LQ-7 equivalent, this device delivers verified low VF performance in high-density power supplies, battery protection circuits, and automotive body electronics where thermal efficiency and space-constrained layout are critical.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient voltage immunity and supports continuous operation from –65°C to +125°C junction temperature. Its 6.0°C/W junction-to-solder-point thermal resistance enables efficient heat transfer to PCB copper when mounted per recommended pad layout.
The device exhibits 40pF total capacitance at 10V reverse bias and maintains ≤0.45V forward voltage at 2.0A/25°C, enabling high-efficiency synchronous rectifier replacement in low-voltage DC-DC stages without gate drive complexity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24V automotive and 5–12V industrial power rails. |
| IF(AV) | 2.0 A - Average forward current rating; supports continuous conduction mode in compact buck converters and OR-ing diode applications. |
| VF @ 2.0A/25°C | 0.36 V - Measured forward voltage drop; reduces conduction loss by ~40% vs. standard silicon diodes, improving system efficiency. |
| IFSM | 30 A - Non-repetitive peak surge current (8.3ms half-sine); withstands load dump transients in automotive 12V systems. |
| RθJS | 6.0 °C/W - Junction-to-solder-point thermal resistance; enables direct thermal coupling to PCB copper for passive cooling in space-limited designs. |
| CT @ 10V | 40 pF - Total junction capacitance; minimizes switching noise and EMI in high-frequency (>1MHz) DC-DC topologies. |
Pinout & Package
Package: POWERDI®323 - ultra-small surface-mount plastic package (2.50 × 1.90 × 0.13 mm), UL 94V-0 rated, with matte tin-plated copper leadframe and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side (e.g., switch node in buck converter); requires minimum 0.60 mm pad width per AP02001. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output rail or ground return; serves as primary heat path to PCB copper pour. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB330-E3/57T (Vishay) | Same 30V/2A rating but TO-277 package (3.5×2.7×1.0mm); VF = 0.45V @ 2A/25°C; RθJA = 100°C/W. | Larger footprint and higher thermal resistance limit use in ultra-thin or high-density layouts. | Select when legacy TO-277 compatibility or higher surge margin (40A IFSM) is required over size reduction. |
| SS23 (ON Semiconductor) | SOD-323 package (1.7×1.3×0.9mm); VF = 0.35V @ 2A/25°C; but only 20A IFSM and no AEC-Q101 qualification. | Not suitable for automotive transients; lower surge rating risks failure during cold-crank events. | Prefer for cost-sensitive consumer wearables where AEC-Q101 is unnecessary and 0.2mm height saving is critical. |
Compared with SB330-E3/57T and SS23, PD3S230LQ-7 uniquely balances ultra-compact POWERDI323 size, AEC-Q101 compliance, and 30A surge robustness-making it optimal for next-gen automotive and portable medical power paths where space, reliability, and transient resilience are co-constrained.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PD3S230LQ-7 has a specified operating junction temperature range of –65°C to +125°C. Continuous operation at +125°C is permitted when thermal design meets the 6.0°C/W RθJS limit and ambient conditions stay within derated IF(AV) per Figure 5. Exceeding this temperature risks accelerated parametric drift and reduced lifetime.
Is the POWERDI323 package compatible with standard reflow profiles?
Yes-the PD3S230LQ-7 is qualified for lead-free reflow per JEDEC J-STD-020, with moisture sensitivity level 1. It supports peak temperatures up to 260°C for ≤60 seconds and ramp rates ≤3°C/s, provided the recommended pad layout (AP02001) and 2 oz. copper thermal relief are implemented.
How does the guard ring construction improve real-world reliability?
The guard ring die structure suppresses edge breakdown during voltage transients, reducing reverse leakage growth after repeated 30V+ surges. This extends operational life in automotive environments subject to ISO 7637-2 pulses and improves long-term stability in battery-powered devices exposed to thermal cycling.
Can PD3S230LQ-7 replace a standard PN junction diode in an existing 12V power supply?
Yes-its 30V VRRM and 2.0A IF(AV) match common 1N5819 replacements, while its 0.36V VF at 2.0A/125°C lowers conduction loss by ~0.25W per diode versus typical 0.55V silicon diodes, directly improving efficiency and reducing thermal stress on adjacent components.
