Product details
Overview
PDS1040-13 from Diodes Incorporated is a 10A, 40V Schottky barrier rectifier in PowerDI®5 package, featuring 0.45V forward voltage at 8A/25°C, 275A non-repetitive surge capability, and <0.02mA reverse leakage at 35V/25°C. It serves as a low-loss freewheeling diode in DC-DC converters and polarity protection switch in 12V automotive power rails.
For engineers reviewing the PDS1040-13 datasheet, PDS1040-13 pinout, PDS1040-13 application, or PDS1040-13 equivalent, key selection criteria include thermal resistance (RθJS = 1.5°C/W), junction temperature range (–65°C to +150°C), and RoHS-compliant matte tin annealed terminals with J-STD-020 Level 1 moisture sensitivity.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche breakdown and sustain high surge current without degradation. Its low VF and ultra-low IR are achieved via optimized platinum-silicide metallization and epitaxial anode design.
Thermal performance depends critically on PCB layout: RθJA ranges from 50°C/W (large copper pads) to 95°C/W (minimum FR-4 pad), requiring explicit thermal pad sizing per Diodes' recommended footprint for 10A continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 40 V - blocks up to 40V DC or peak AC before breakdown; sets max input voltage in buck converter output stage |
| Forward Voltage | 0.45 V @ 8A/25°C - reduces conduction loss to ≤3.6W at full load, enabling compact thermal design |
| Surge Current | 275 A @ 8.3ms - withstands inrush and fault currents in automotive load-dump scenarios |
| Reverse Leakage | 0.02 mA @ 35V/25°C - minimizes standby power loss in always-on battery-connected circuits |
| Junction-to-Solder Point RθJS | 1.5 °C/W - enables direct thermal coupling to PCB copper pour for efficient heat extraction |
| Operating Junction Temp | –65°C to +150°C - supports under-hood automotive environments with 80% VRRM derating above +125°C |
Pinout & Package
Package: PowerDI®5 - surface-mount, 3-terminal molded plastic case (UL 94V-0), 0.096g mass, lead-free matte tin over copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Low-inductance terminal for high-di/dt switching nodes; requires 2.7mm × 1.6mm minimum copper pad |
| Pin 2 (Cathode) | Cathode connection | Main current return path; designed for 9.4mm × 7.2mm thermal pad to achieve RθJA = 75°C/W |
| Pin 3 (Cathode) | Cathode connection | Second cathode terminal for parallel current paths and enhanced thermal spreading |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche during voltage transients, improving reliability in noisy automotive environments |
| Low forward voltage drop | 0.45V at 8A/25°C - cuts conduction loss by ≥40% vs. standard silicon rectifiers at same current |
| High surge current rating | 275A single half-sine - eliminates need for external TVS in many 12V supply protection designs |
| Halogen & antimony free | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets automotive OEM green material specifications |
Applications
| DC-DC Converter Freewheeling | Automotive Polarity Protection |
|---|---|
Use Scenario: Used as synchronous rectifier or freewheeling diode in 12V-to-5V/3.3V buck converters for infotainment ECUs. IC Role / Device Role / Timing Role: Freewheeling diode conducting during low-side switch off-time to maintain inductor current continuity. Use Value: 0.45V VF reduces power loss by ~2.2W vs. 0.7V Si diode at 10A, lowering heatsink requirements. | Use Scenario: Placed in series with battery input to prevent damage from reverse battery connection in telematics modules. IC Role / Device Role / Timing Role: Unidirectional current gate blocking reverse polarity while passing normal 12V supply. Use Value: 275A IFSM handles jump-start surges without failure; <0.02mA IR avoids battery drain in sleep mode. |
| Low-Voltage Inverter Output | Industrial Power Supply OR-ing |
Use Scenario: Output rectification in 24V AC-DC inverters for LED drivers and motor controls. IC Role / Device Role / Timing Role: High-frequency rectifier converting high-frequency AC from H-bridge to DC output. Use Value: Low junction capacitance (<1000pF @ 0V) minimizes switching losses at 50–100kHz operation. | Use Scenario: OR-ing diode in redundant 48V telecom power supplies to isolate failed rails. IC Role / Device Role / Timing Role: Forward-biased conduction path enabling hot-swap redundancy without backfeed. Use Value: 10A IO rating supports >95% efficiency at full load; RθJS = 1.5°C/W allows direct PCB thermal anchoring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS1040-13 (Diodes Inc.) | Same 40V/10A rating but in SMA package; RθJA = 120°C/W; VF = 0.52V @ 10A | Limited to ≤3A continuous in open air; unsuitable for high-power density layouts | Select when board space permits larger footprint and thermal budget allows higher VF loss |
| MBR1045CT (ON Semiconductor) | 45V/10A dual common-cathode; VF = 0.55V @ 10A; TO-220AC package; RθJA = 50°C/W | Requires through-hole mounting and heatsink; dual configuration enables center-tap rectification | Select for legacy through-hole designs or dual-output rectification where discrete cathodes are needed |
Compared with SS1040-13 and MBR1045CT, PDS1040-13 delivers superior thermal performance in SMT form factor (RθJS = 1.5°C/W), lower VF for reduced conduction loss, and automotive-qualified robustness-making it optimal for space-constrained, high-efficiency 12V/24V systems.

FAQ
What is the maximum continuous forward current for PDS1040-13 at 100°C ambient?
At 100°C ambient temperature on a FR-4 PCB with minimum recommended pad layout (Note 5), the derated average forward current is approximately 5.5A. This is derived from Figure 6, which shows linear derating from 10A at 25°C to 0A at ~135°C for that layout condition.
Is PDS1040-13 qualified for automotive use?
No-only the PDS1040Q-13 variant is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. The PDS1040-13 is industrial-grade and lacks automotive change control documentation and qualification testing.
How does the PowerDI®5 package improve thermal performance over SMA?
The PowerDI®5's dual cathode terminals and exposed thermal pad enable direct solder attachment to large PCB copper areas, achieving RθJS = 1.5°C/W-over 4× better than SMA's typical RθJA of 70°C/W-allowing 10A operation without a heatsink in properly laid out designs.
Can PDS1040-13 replace a 40V/8A Schottky in an existing design?
Yes-its 10A rating provides 25% headroom over 8A requirements, and its 0.45V VF at 8A matches or exceeds most 8A-rated Schottkys. Verify thermal pad layout compatibility with PowerDI®5 footprint and ensure cathode pad area meets ≥9.4mm × 7.2mm for target RθJA.
