Diodes Incorporated SDT10H50P5-13

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 rating-optimized for high-efficiency DC/DC converters and AC/DC adapters.

For engineers reviewing the SDT10H50P5 datasheet, SDT10H50P5 pinout, SDT10H50P5 application, or SDT10H50P5 equivalent, this device offers verified thermal performance (R_θJC = 3°C/W with heatsink), soft fast switching behavior, and RoHS-compliant lead-free construction suitable for industrial power supply design and automotive-grade derivative evaluation.

Technical Context

This Schottky rectifier uses trench MOS-based anode structure to achieve low VF and stable IR across temperature-VF remains ≤0.45V up to +125°C and IR stays ≤0.30mA at 50V bias and +125°C. Its 320A non-repetitive surge rating supports transient load handling in switch-mode topologies.

The PowerDI5 package enables dual thermal paths: R_θJA = 25°C/W when mounted on a 2"×2" aluminum heatsink, and R_θJC = 3°C/W confirms efficient junction-to-case conduction-critical for compact, high-power-density designs where ambient cooling is limited.

FAQ

What is the thermal resistance from junction to case (R_θJC) for SDT10H50P5, and under what conditions is it measured?

The typical R_θJC is 3°C/W, measured when the device is mounted on a 2-inch × 2-inch aluminum heatsink per Note 7 in the datasheet. This value reflects direct conduction from die to heatsink via the exposed cathode pad and is critical for accurate junction temperature estimation in high-power layouts.

Can SDT10H50P5 replace standard silicon rectifiers in existing 50V designs?

Yes-it can directly replace 50V silicon diodes (e.g., 1N5408) in most cases, delivering lower V_F (0.45V vs. ~0.9V), reduced conduction loss, and faster recovery. However, verify reverse voltage margin and thermal layout, as Schottky leakage rises with temperature and requires adequate heatsinking at high ambient.

Is SDT10H50P5 qualified for automotive applications per AEC-Q101?

No-the SDT10H50P5 is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., SDT10H50Q5) with PPAP documentation and IATF 16949 manufacturing; contact their automotive team for qualified alternatives meeting AEC requirements.

What does the "P5" suffix in SDT10H50P5 indicate?

The "P5" denotes the PowerDI5 package variant-distinct from TO-220, SMA, or SMC versions. It confirms the 3-terminal surface-mount outline with exposed cathode pad, standardized dimensions (e.g., D = 3.966 mm, E = 6.51 mm), and thermal performance characteristics defined in DS40260 Rev. 4-2.
