Product details
Overview
PDS4150-13 from Diodes Incorporated is a 4A, 150V high-voltage Schottky barrier rectifier in PowerDI5 package, featuring 0.76V max forward voltage at 4A/25°C, <0.01mA reverse leakage at 150V/25°C, and AEC-Q101 qualification for automotive polarity protection and flyback diode applications.
For engineers reviewing the PDS4150-13 datasheet, PDS4150-13 pinout, PDS4150-13 application, or PDS4150-13 equivalent, key selection criteria include its low VF stability over temperature, 180A non-repetitive surge rating, junction-to-solder thermal resistance of 2.0°C/W, and guard ring die construction for transient robustness in 12V/24V automotive power rails.
Technical Context
This Schottky rectifier uses oxide-passivated, highly stable junction technology with guard ring die construction to suppress edge breakdown and improve transient immunity. Its low forward voltage drop is maintained across -65°C to +175°C operating range, supported by 175°C maximum junction temperature rating.
Thermal performance is optimized for surface-mount PCB mounting: RθJS = 2.0°C/W (junction-to-solder point), with RθJA varying from 40–90°C/W depending on pad layout (FR-4 vs. polyimide, cathode pad size). Reverse leakage remains below 0.4mA at 150V/125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (VRRM) | 150 V - Maximum repetitive reverse blocking voltage; supports 24V automotive systems with 3× safety margin against load dump transients. |
| IF(AV) | 4 A - Average rectified output current; rated for continuous conduction in DC-DC output stages or motor recirculation paths. |
| VF(max) | 0.76 V @ 4A/25°C - Low conduction loss enables >95% efficiency in 12V–24V buck converters and reduces thermal stress on PCB copper. |
| IR(max) | 0.01 mA @ 150V/25°C - Ultra-low leakage preserves battery standby life in always-on automotive modules. |
| IFSM | 180 A @ 8.3ms - Withstands motor stall surges and inductive kickback without degradation in engine control units. |
| TJ(max) | +175°C - Enables operation in under-hood environments without derating in high-ambient industrial or automotive enclosures. |
| RθJS | 2.0 °C/W - Enables direct thermal coupling to PCB copper pour for passive cooling in space-constrained modules. |
Pinout & Package
Package: PowerDI5 - Surface-mount plastic package with matte tin–annealed copper leadframe, UL 94V-0 rated molding compound, and 0.096g mass. Optimized for automated assembly and high-power density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V4P15-M3/86A | 150V, 4A, VF = 0.79V @ 4A/25°C; RθJA = 65°C/W (FR-4); no AEC-Q101 certification. | Qualified for industrial/commercial use only; not approved for automotive production. | Select when AEC-Q101 compliance is not required and higher VF is acceptable for cost-sensitive designs. |
| ON Semiconductor SB4150-T3 | 150V, 4A, VF = 0.75V @ 4A/25°C; RθJS = 2.5°C/W; AEC-Q101 qualified but with lower IFSM (120A). | Limited surge capability makes it unsuitable for high-inductance motor loads. | Select for low-VF priority in non-motor applications where 120A surge margin suffices. |
Compared with V4P15-M3/86A and SB4150-T3, PDS4150-13 uniquely combines AEC-Q101 qualification, 180A surge rating, and 2.0°C/W RθJS-making it optimal for thermally constrained, high-reliability automotive power nodes where both transient robustness and thermal efficiency are critical.

FAQ
Is PDS4150-13 suitable for synchronous rectification?
No. PDS4150-13 is a unidirectional Schottky rectifier, not a controlled switch. It lacks gate terminals or logic interface and cannot replace MOSFETs in synchronous rectifier topologies. Its role is strictly passive freewheeling or polarity protection.
What is the recommended PCB pad layout for thermal performance?
Per Diodes datasheet DS30473, use a 9.4mm × 7.2mm cathode pad and 2.7mm × 1.6mm anode pad on 2 oz. polyimide PCB. This achieves RθJA = 40°C/W. Smaller pads on FR-4 increase RθJA to 90°C/W and require derating above 65°C ambient.
Does PDS4150-13 have a built-in TVS function?
No. While its guard ring die construction improves transient immunity, it is not rated or tested as a TVS device. It does not meet IEC 61000-4-2/4-5 standards for ESD or surge suppression and must be paired with dedicated TVS diodes for system-level protection.
Can PDS4150-13 be used in AC line rectification?
No. With VR(RMS) = 106V, it is unsuitable for 120VAC or 230VAC full-wave rectification. Its 150V VRRM rating provides only ~1.4× margin over 106V RMS, insufficient for peak line voltages (170V/325V) and safety derating requirements in mains-connected equipment.
