Product details
Overview
PDS1045Q-13D from Diodes Incorporated is a 10A, 45V Schottky barrier rectifier in PowerDI5 package, featuring 0.51V max forward voltage at 10A/25°C, 0.6mA max reverse leakage at 45V/125°C, and 275A non-repetitive surge capability. It serves as a low-loss freewheeling diode in automotive DC-DC converters and polarity protection circuits.
For engineers reviewing the PDS1045Q-13D datasheet, PDS1045Q-13D pinout, PDS1045Q-13D application, or PDS1045Q-13D equivalent, key selection criteria include its AEC-Q101 qualification, 18°C/W thermal resistance on 2"×2" aluminum board, guard ring die construction for transient robustness, and RoHS-compliant green molding compound.
Technical Context
This Schottky rectifier uses planar guard ring die architecture to suppress edge breakdown and improve surge immunity. Its low VF (0.45V typ. @10A/25°C) and high IFSM (275A) enable efficient operation in high-frequency switching topologies with minimal conduction loss.
Thermal performance is defined by dual RθJA ratings: 85°C/W on standard FR-4 and 18°C/W on 2"×2" Al board-enabling design flexibility across consumer, industrial, and automotive ambient conditions up to +125°C junction temperature.

| Vishay VS-10BQ040-M3/45 | 40V VRRM, 0.49V VF max @10A/25°C, TO-277 package | Lacks AEC-Q101 qualification; not PPAP-capable | Select when automotive qualification is unnecessary and TO-277 footprint compatibility is required. |
| ON Semiconductor SB1040 | 40V VRRM, 0.55V VF max @10A/25°C, SMA package | SMA package has higher RθJA (≥65°C/W); limited to ≤5A continuous in same thermal environment | Choose for cost-sensitive industrial designs where 40V rating suffices and space constraints favor SMA. |
Compared with VS-10BQ040-M3/45 and SB1040, PDS1045Q-13D delivers higher reverse voltage margin (45V vs. 40V), automotive-grade reliability, and superior thermal performance in PowerDI5-making it optimal for safety-critical 12V/24V vehicle subsystems requiring long-term stability.

FAQ
What is the maximum junction temperature for continuous operation?
The PDS1045Q-13D is rated for continuous operation from –55°C to +150°C junction temperature. At 10A DC current and 25°C ambient on a 2"×2" aluminum board, junction temperature remains below 125°C due to its 18°C/W RθJA, satisfying AEC-Q101 thermal stress requirements.
Is the PowerDI5 package lead-free and RoHS compliant?
Yes. The PDS1045Q-13D uses matte tin annealed over copper leadframe and green molding compound meeting EU RoHS 3 (2015/863/EU), with bromine and chlorine each <900ppm and antimony <1000ppm-fully documented in Diodes' Green Product Definitions.
How does the guard ring die construction improve reliability?
The guard ring structure surrounds the active junction to distribute electric field gradients, preventing premature edge breakdown during voltage transients like ISO 7637-2 pulse 5a (load dump). This extends device lifetime in automotive environments where 100V+ spikes occur routinely.
Can PDS1045Q-13D replace traditional silicon rectifiers in existing designs?
Yes-provided reverse voltage requirements stay within 45V. Its lower VF reduces conduction loss by ~0.3V versus 1N5822-type silicon diodes at 10A, lowering thermal stress and potentially eliminating heatsinks. Layout must accommodate PowerDI5's exposed cathode pad for optimal thermal performance.
