Product details
Overview
SDT10A45P5 from Diodes Incorporated is a 10A, 45V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.47V max forward voltage at 10A/25°C, 0.3mA max reverse leakage at 45V/25°C, and 150°C max junction temperature. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters.
For engineers reviewing the SDT10A45P5 datasheet, SDT10A45P5 pinout, SDT10A45P5 application, or SDT10A45P5 equivalent, key selection criteria include low VF for conduction loss reduction, thermal stability up to 150°C, soft switching behavior for EMI control, and PowerDI5's 18°C/W RθJA on aluminum substrate.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower VF and higher current density than planar Schottky diodes. Its soft recovery minimizes voltage ringing during turn-off, reducing snubber requirements in synchronous buck outputs.
Thermal performance is optimized for surface-mount power delivery: RθJC = 2°C/W (on 2"×2" Al substrate) enables high-current operation without external heatsink, while 10A average current rating assumes FR-4 PCB with 2oz copper and minimum recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse blocking voltage; defines safe operating range in DC-DC secondary-side or AC-DC input bridge configurations. |
| IO (AV) | 10 A - Continuous average forward current at TA = 25°C; derates to ~6.5A at TA = 85°C per Figure 4. |
| VF (max) | 0.47 V @ 10A, 25°C - Low conduction loss enables >95% efficiency in 12V→5V/3.3V point-of-load converters. |
| IR (max) | 0.3 mA @ 45V, 25°C - Ultra-low leakage preserves standby power in always-on systems; rises to 80 µA at 125°C. |
| TJ (max) | +150°C - Enables operation in thermally constrained enclosures without forced air cooling. |
| RθJA | 18 °C/W - Measured on 2"×2" aluminum substrate; supports 5.6W continuous dissipation at ΔT = 100°C. |
| Capacitance | 1000 pF @ 0V - Low junction capacitance reduces switching loss and improves high-frequency rectification fidelity. |
Pinout & Package
Package: PowerDI5 - Surface-mount, thermally enhanced plastic package with exposed cathode pad; 3.966 mm × 6.51 mm footprint; 1.10 mm height; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to switch node (e.g., buck converter high-side FET drain); requires low-inductance routing. |
| Cathode | Current exit terminal & thermal path | Large exposed metal pad; must be soldered to ≥200 mm² copper pour for optimal RθJA = 18°C/W. |
| Case (exposed pad) | Thermal interface only | Electrically isolated from internal die; serves solely as heat spreader to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables 0.47V VF at 10A - 15–20% lower than comparable planar Schottky diodes, directly reducing I²R losses. |
| Soft, fast switching | Minimal reverse recovery charge (QRR < 10 nC typical) - suppresses voltage overshoot and EMI in high-dV/dt environments. |
| +150°C junction rating | Supports full 10A current in sealed industrial enclosures with ambient up to +85°C without derating. |
| PowerDI5 thermal design | 2°C/W RθJC - allows >90% of die heat to transfer directly to PCB, eliminating need for discrete thermal vias in many designs. |
Applications
| DC-DC Converters | AC-DC Adaptors |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 48V→12V telecom power supplies. IC Role / Device Role / Timing Role: Freewheel diode replacing MOSFET gate driver complexity; conducts during low-side FET off-time. Use Value: 0.47V VF cuts conduction loss by 300 mW vs. 0.77V Si diode at 10A, improving full-load efficiency by 0.8%. | Use Scenario: Output rectification in compact 65W laptop adapters. IC Role / Device Role / Timing Role: Output blocking diode in flyback secondary winding. Use Value: 0.3mA IR at 25°C ensures <10 µW standby loss; stable leakage at 125°C maintains Energy Star compliance. |
| Industrial Motor Drives | LED Lighting Drivers |
Use Scenario: Freewheel path for 24V BLDC gate driver bootstrap circuits. IC Role / Device Role / Timing Role: Clamp diode across inductive gate drive transformer secondary. Use Value: Soft recovery prevents 100V+ ringing spikes that could damage level-shift ICs or cause false triggering. | Use Scenario: Constant-current regulation loop rectifier in 100W streetlight LED drivers. IC Role / Device Role / Timing Role: High-side current sense shunt bypass diode during PWM off-cycle. Use Value: 150°C TJ rating allows placement near LED heatsink without thermal derating, simplifying board layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V10P45-M3/86A | Same 45V/10A rating; VF = 0.52V max @ 10A; RθJA = 25°C/W on FR-4. | Higher VF increases conduction loss by ~0.5W; less suitable for thermally dense 12V→5V converters. | Prefer when cost sensitivity outweighs 0.05V VF advantage and thermal margin is ample. |
| ON Semiconductor SB1045-TB | TO-277 package; VF = 0.50V max; RθJA = 35°C/W; no exposed thermal pad. | Larger footprint and inferior thermal resistance limit usable current to ≤7A in same PCB area. | Select only if legacy TO-277 footprint compatibility is required and space permits larger outline. |
Compared with V10P45-M3/86A and SB1045-TB, SDT10A45P5 delivers lowest system-level thermal resistance and highest efficiency density due to PowerDI5's 2°C/W RθJC and 0.47V VF-critical for miniaturized, fanless power supplies.

FAQ
What is the maximum allowable PCB pad size for optimal thermal performance?
The datasheet specifies a minimum recommended pad layout on its package outline page. For RθJA = 18°C/W, use a 2-inch × 2-inch aluminum substrate; for FR-4, apply ≥200 mm² copper pour connected via ≥6 thermal vias (0.3mm diameter, 0.8mm pitch) under the exposed cathode pad. Larger pads improve heat spreading but do not reduce RθJC below 2°C/W.
Does SDT10A45P5 have a built-in guard ring or field plate?
No. The device uses a trench Schottky structure without discrete guard ring or field plate. Edge termination relies on mesa isolation and passivation layers, validated by 100% wafer-level high-potential testing at 1.5×VRRM (67.5V) per production lot.
Can SDT10A45P5 replace a silicon PN rectifier in an existing design?
Yes-if reverse voltage does not exceed 45V and surge current remains below 180A. Replace with direct footprint compatibility, but verify reduced VF does not cause control-loop instability in voltage-mode controllers due to faster current rise times and lower output impedance.
Is the PowerDI5 package lead-free and halogen-free per JEDEC standards?
Yes. SDT10A45P5 meets J-STD-020 moisture sensitivity Level 1, has lead-free finish per RoHS 3 (2015/863/EU), and is halogen-free (<900ppm Br, <900ppm Cl, <1000ppm Sb), certified "Green" per Diodes Incorporated's specification document G-01-001.
