Product details
Overview
PDS1045-13 from Diodes Incorporated is a 10A, 45V Schottky barrier rectifier in POWERDI®5 package, featuring 0.45V forward voltage at 10A/25°C, 275A non-repetitive surge capability, and AEC-Q101 qualification for automotive-grade reliability-used in low-voltage DC-DC freewheeling paths and polarity protection circuits.
For engineers reviewing the PDS1045-13 datasheet, PDS1045-13 pinout, PDS1045-13 application, or PDS1045-13 equivalent, key selection criteria include forward voltage at rated current, thermal resistance under defined PCB layouts (RθJA = 50–85°C/W), reverse leakage at elevated temperature, and guard ring–enabled transient robustness in high-frequency switching environments.
Technical Context
This Schottky rectifier employs guard ring die construction to suppress edge breakdown and improve surge immunity during inductive load commutation. Its low VF (0.45V max @ 10A, 25°C) minimizes conduction loss in 12V/24V automotive and industrial power rails.
Thermal performance is layout-dependent: RθJA ranges from 50°C/W (large cathode pad on polyimide) to 85°C/W (FR-4 baseline), with RθJS fixed at 0.8°C/W-enabling accurate junction temperature estimation when solder-point temperature is monitored.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 36V nominal systems. |
| IO | 10 A - Average rectified output current; sustained DC conduction rating under specified thermal conditions. |
| VF @ 10A, 25°C | 0.45 V - Forward voltage drop; determines power loss (4.5W) and thermal load at full rated current. |
| IFSM | 275 A - Non-repetitive peak surge current (8.3ms half-sine); supports motor startup and inductive turn-off transients. |
| RθJS | 0.8 °C/W - Junction-to-solder-point thermal resistance; enables precise thermal modeling when board-level cooling is controlled. |
| IR @ 45V, 125°C | 150 µA - Reverse leakage at max rated voltage and high temperature; impacts standby power in always-on systems. |
Pinout & Package
Package: POWERDI®5 - surface-mount, single-diode configuration with exposed cathode pad for enhanced thermal dissipation; molded green compound, UL 94V-0 rated, 0.096g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point | Connected to input/source side; requires minimal copper area (2.7mm × 1.6mm recommended). |
| Cathode | Current exit point / heat sink node | Primary thermal path; large pad (9.4mm × 7.2mm minimum) required for RθJA = 50°C/W performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB1040-TB | 40V VRRM, 0.55V VF @ 10A - lower voltage rating, higher conduction loss. | Not suitable for 45V transient-tolerant designs; limited to ≤36V nominal systems. | Select only if system max reverse voltage stays below 40V and thermal margin allows +0.1V VF penalty. |
| SS1045S-13-F | Same 45V/10A rating but SMB package - RθJA ≈ 100°C/W, no exposed thermal pad. | Limited to lower-power applications; unsuitable for sustained 10A without forced air or oversized copper. | Choose only for space-constrained layouts where POWERDI®5 footprint is unavailable and thermal load is <5A average. |
Compared with SB1040-TB and SS1045S-13-F, PDS1045-13 delivers superior thermal performance via its exposed cathode pad and tighter VF spec, making it the preferred choice for automotive and industrial 10A freewheeling or protection where reliability and efficiency are co-prioritized.

FAQ
What is the maximum junction temperature for continuous operation?
The PDS1045-13 supports continuous operation up to +150°C junction temperature when reverse voltage is held at ≤50% of VRRM (i.e., ≤22.5V). At full 45V blocking, the max continuous TJ is +125°C. Derating curves in Figure 6 define allowable ambient temperature versus applied reverse voltage.
Is the POWERDI®5 package lead-free and RoHS-compliant?
Yes. The PDS1045-13 uses matte tin annealed over copper leadframe and green molding compound, meeting EU RoHS 2 (2011/65/EU) requirements and Diodes Incorporated's Halogen- and Antimony-Free "Green" definition (<900ppm Br/Cl, <1000ppm Sb).
How does the guard ring construction improve reliability?
The guard ring mitigates electric field crowding at the silicon periphery, preventing premature edge breakdown during voltage transients. This extends device lifetime in inductive switching applications like motor drives and DC-DC converters where dV/dt stress is common.
Can PDS1045-13 replace a standard silicon rectifier in an existing design?
Yes-if the circuit operates below 45V reverse voltage and benefits from lower forward drop. However, Schottky devices exhibit higher reverse leakage than silicon, especially at elevated temperatures; verify that 150µA @ 125°C does not impact system standby power or sensing accuracy before substitution.
