Product details
Overview
SDT10H50P5 from Diodes Incorporated is a 10A, 50V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.45V max forward voltage at 10A/25°C, 0.30mA max reverse leakage at 50V/125°C, and 150°C junction temperature rating. It serves as a high-efficiency freewheel or output rectifier in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SDT10H50P5 datasheet, SDT10H50P5 pinout, SDT10H50P5 application, or SDT10H50P5 equivalent, key selection criteria include low VF stability across temperature, thermal resistance to case (3°C/W with heatsink), soft switching behavior, and RoHS-compliant green packaging for space-constrained power stages.
Technical Context
This Schottky rectifier uses trench MOSFET-inspired process technology to achieve lower forward voltage and superior high-temperature leakage control versus planar Schottkys. Its unidirectional conduction path supports continuous 10A DC output current with derating above 25°C ambient.
The device operates up to +150°C junction temperature and exhibits soft reverse recovery-critical for reducing EMI in high-frequency switching topologies like synchronous buck converters. Thermal resistance junction-to-case is 3°C/W when mounted on a 2"×2" aluminum heatsink, enabling high-power density designs without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum blocking voltage before breakdown; sets upper limit for input/output rail separation in isolated/non-isolated converters |
| IO(AV) | 10 A - Continuous DC output current capability at 25°C ambient; derates to ~6.5A at 70°C per Figure 3 |
| VF(max) | 0.45 V @ 10A, 25°C - Low conduction loss enables >95% efficiency in 5–12V output stages |
| IR(max) | 0.30 mA @ 50V, 125°C - Stable leakage ensures minimal standby power loss in always-on adapter designs |
| TJ(max) | +150°C - Enables operation in sealed enclosures or high-ambient industrial environments without thermal shutdown |
| RθJC | 3°C/W - With heatsink mounting, allows ~3.3W dissipation before reaching 150°C junction limit |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced 3-pin plastic package with exposed cathode pad; dimensions 3.966mm × 6.51mm × 1.10mm (L×W×A); UL 94V-0 rated molding compound; matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to switch node or transformer secondary in flyback/buck topologies |
| Pin 2 | Cathode (Exposed Pad) | Main current return path and primary thermal interface; must be soldered to large copper pour or heatsink |
| Pin 3 | Anode | Second anode connection; paralleled internally with Pin 1 to share 10A current and reduce bondwire resistance |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables 0.45V VF at 10A while maintaining <0.3mA IR at 125°C-unachievable with planar Schottky diodes of same rating |
| Soft, fast switching | No minority-carrier storage; eliminates reverse recovery spikes-reduces EMI filter size and snubber losses in 300–1000kHz converters |
| PowerDI5 thermal design | Exposed cathode pad delivers 3°C/W RθJC with heatsink-supports 3.3W continuous dissipation without fan or heat pipe |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); meets IEC 61249-2-21 and JEDEC JS709C requirements |

FAQ
What is the maximum continuous forward current rating for SDT10H50P5-13D at 70°C ambient?
At 70°C ambient temperature, the SDT10H50P5-13D supports approximately 6.5A average rectified output current, based on the derating curve in Figure 3 of DS40260 Rev. 4–2. This assumes use of the recommended minimum PCB pad layout on FR-4 with 2oz copper; performance improves with heatsink mounting.
Does SDT10H50P5-13D have a documented AEC-Q101 qualification for automotive use?
No-SDT10H50P5-13D is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; those are offered under separate part numbers (e.g., SDT10H50Q5 series) and must be requested directly from Diodes Incorporated.
How does the PowerDI5 package improve thermal performance compared to SMA or SMB packages?
The PowerDI5 package features an exposed cathode pad that serves as both electrical terminal and primary thermal path. With RθJC = 3°C/W (vs. >20°C/W for SMA), it transfers heat directly to PCB copper or heatsink-enabling 3× higher power dissipation than SMA-encapsulated Schottkys at the same footprint.
Can SDT10H50P5-13D replace a standard 10A silicon rectifier like 10BQ015 in a 5V/10A SMPS?
Yes-SDT10H50P5-13D can replace 10BQ015 in 5V-output SMPS, delivering immediate efficiency gains: its 0.45V VF reduces conduction loss by ~4.5W versus 10BQ015's typical 0.55V, lowering thermal stress and eliminating need for snubbers due to absence of reverse recovery charge.
