Product details
Overview
PDS4150Q-13 from Diodes Incorporated is an AEC-Q101-qualified 4A, 150V 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 180A non-repetitive surge capability - deployed as polarity protection and freewheeling diode in automotive power modules.
For engineers reviewing the PDS4150Q-13 datasheet, PDS4150Q-13 pinout, PDS4150Q-13 application, or PDS4150Q-13 equivalent, key selection criteria include automotive-grade reliability (AEC-Q101), low VF for efficiency-critical 12V/24V systems, thermal resistance of 2.0°C/W (junction-to-solder point), and PowerDI5 footprint compatibility with high-density PCB layouts.
Technical Context
This discrete Schottky rectifier uses oxide-passivated, guard-ring die construction to suppress transient-induced junction failure and sustain operation up to +175°C junction temperature. Its low-leakage design (<0.4mA at 150V/125°C) enables stable blocking in high-temperature engine-bay environments.
The device delivers 4A average rectified current with derating curves defined for FR-4 (90°C/W), polyimide (60°C/W), and enhanced polyimide (40°C/W) PCBs - enabling thermal optimization based on board material and pad layout per Diodes' recommended footprint.
Key Specifications

Applications
| Engine Control Unit (ECU) Polarity Protection | Electric Power Steering (EPS) Freewheeling Diode |
|---|---|
Use Scenario: Installed between battery input and ECU main power rail to prevent damage from reverse battery connection. IC Role / Device Role / Timing Role: Discrete polarity protection diode - blocks reverse current while conducting forward current with minimal voltage drop. Use Value: 0.76V VF limits power loss to <3W at 4A, reducing thermal stress on PCB traces and connectors. | Use Scenario: Placed across H-bridge motor winding to clamp inductive kickback during PWM commutation. IC Role / Device Role / Timing Role: Recirculating (freewheeling) diode - provides low-impedance return path for stored inductive energy. Use Value: 180A IFSM withstands repeated motor stall surges; 0.01mA IR prevents battery drain during vehicle sleep mode. |
| Body Control Module (BCM) Load Dump Clamping | ADAS Camera Power Supply Output Rectification |
Use Scenario: Used in conjunction with TVS diodes to absorb residual energy after primary clamping in 12V supply lines. IC Role / Device Role / Timing Role: Secondary energy-dissipation diode - conducts sustained post-clamp current without thermal runaway. Use Value: +175°C TJ(max) and 2.0°C/W RθJS allow reliable operation during extended load-dump events (ISO 16750-2). | Use Scenario: Rectifies switched-mode power supply output feeding image sensor and ISP in rear-view camera modules. IC Role / Device Role / Timing Role: Output rectifier in synchronous buck converter - delivers clean, low-noise DC with minimal ripple. Use Value: Low VF and low IR ensure >92% conversion efficiency at 3.3V/2A output, extending module runtime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB4150-TB | Same 150V/4A rating, but TO-277 package; RθJA ≈ 50°C/W on FR-4 vs. PowerDI5's 90°C/W. | Larger footprint; less suitable for ultra-thin automotive modules requiring low profile. | Choose when legacy TO-277 layout reuse is prioritized over thermal performance density. |
| SS5P15L | 150V/5A, but VF = 0.82V @ 5A/25°C; not AEC-Q101 qualified; RθJS = 2.5°C/W. | Higher current rating but lower reliability assurance for automotive production programs. | Acceptable for industrial prototypes where AEC-Q101 is not mandated and 1A headroom is needed. |
Compared with SB4150-TB and SS5P15L, PDS4150Q-13 uniquely combines AEC-Q101 qualification, PowerDI5's superior thermal resistance (2.0°C/W), and lowest VF in its class - making it optimal for space-constrained, high-reliability automotive power rails.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PDS4150Q-13 has a rated maximum junction temperature of +175°C, verified per AEC-Q101 stress testing. Continuous operation at this temperature requires adherence to the derating curve in Figure 5 and proper PCB thermal design - specifically, use of the recommended PowerDI5 pad layout on polyimide substrate with 2 oz. copper to achieve RθJA ≤ 40°C/W.
Is the PowerDI5 package compatible with standard reflow profiles?
Yes - the PowerDI5 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260°C. The matte tin annealed finish ensures reliable wetting, and moisture sensitivity level is rated at Level 1, eliminating bake requirements prior to assembly.
How does the guard ring structure improve reliability in automotive applications?
The guard ring die construction electrically isolates the active junction periphery, preventing premature avalanche breakdown at chip edges during fast-rising transients like ISO 7637-2 Pulse 1 and Pulse 5a. This extends device lifetime in noisy 12V systems where voltage spikes exceed nominal ratings.
Can PDS4150Q-13 replace PDS4150-13 in standard applications?
Yes - both share identical electrical and thermal specifications. The "Q" suffix denotes AEC-Q101 qualification and PPAP capability; the standard PDS4150-13 is functionally identical but lacks automotive-specific test documentation and traceability. For non-automotive designs, either may be used interchangeably.
