Product details
Overview
PD3S230L-7 from Diodes Incorporated is a 30V, 2.0A surface-mount Schottky barrier rectifier in the POWERDI®323 package, featuring ultra-low forward voltage (0.37V at 2.0A, 25°C), high surge capability (30A IFSM), and AEC-Q101 qualification for automotive reliability. It serves as a primary output rectifier in low-voltage DC/DC converters for infotainment power supplies.
For engineers reviewing the PD3S230L-7 datasheet, PD3S230L-7 pinout, PD3S230L-7 application, or PD3S230L-7 equivalent, key selection criteria include forward voltage at rated current, thermal resistance (RθJS = 6.0°C/W), reverse leakage at 30V (≤250μA), and compatibility with high-density PCB layouts using the 2.5mm × 1.9mm POWERDI323 footprint.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress avalanche-induced failure during load dump events. Its low RθJS enables direct thermal coupling to copper pads without heatsinks in space-constrained automotive modules.
The device operates across –65°C to +125°C junction temperature and maintains ≤0.45V VF at 2.0A and +125°C-critical for maintaining efficiency in under-hood power rails where ambient temperatures exceed 85°C.
Key Specifications

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 SOD-123 package; RθJA = 200°C/W; VF = 0.45V @ 2A. | Larger footprint (3.7mm × 1.6mm); higher thermal resistance limits power density. | Choose when legacy SOD-123 layout reuse is required and space is not constrained. |
| SS23 (ON Semiconductor) | SAME POWERDI323 package; VF = 0.42V @ 2A; IFSM = 25A; no AEC-Q101 qualification. | Lacks automotive qualification; higher VF increases conduction loss by 135mW at 2A. | Acceptable for commercial-grade consumer power supplies where AEC-Q101 is not mandated. |
Compared with SB230-E3/54 and SS23, PD3S230L-7 delivers superior thermal performance (6.0°C/W RθJS), lowest VF (0.37V), and automotive qualification-making it optimal for space-limited, high-reliability 24V system rails where efficiency and transient immunity are critical.

FAQ
What is the maximum operating temperature for PD3S230L-7?
The PD3S230L-7 has a specified junction temperature range of –65°C to +125°C. Its thermal resistance (RθJS = 6.0°C/W) allows full 2.0A operation at +125°C junction temperature when soldered to a properly sized 2oz copper pad, making it suitable for under-hood automotive environments.
Does PD3S230L-7 require a heatsink in typical applications?
No heatsink is required. With RθJS = 6.0°C/W and RθJA = 177°C/W on standard FR-4, the device dissipates ≤0.74W at 2.0A/25°C ambient. At 2.0A and +85°C ambient, junction temperature remains below 125°C using only the recommended 2.5mm × 1.9mm copper pad-no thermal vias or external heatsinking needed.
Is PD3S230L-7 compatible with lead-free reflow processes?
Yes. PD3S230L-7 features a matte tin annealed finish over copper leadframe and is qualified for lead-free reflow per JEDEC J-STD-020. Its MSL Level 1 rating permits unlimited floor life at ≤30°C/60% RH, eliminating bake requirements before assembly.
How does the guard ring construction improve reliability?
The guard ring die structure prevents edge breakdown during voltage transients by controlling electric field distribution at the silicon periphery. This enables reliable operation during ISO 7637-2 Pulse 5a load dump events (up to 100V) and improves ESD robustness-verified by AEC-Q101 HBM testing ≥2kV.
