Diodes Incorporated SDT10100P5-7

Overview

SDT10100P5 from Diodes Incorporated is a 10A, 100V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.70 V max forward voltage at 10 A and 80 µA max reverse leakage at 100 V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters, operating up to +150°C junction temperature.

For engineers reviewing the SDT10100P5 datasheet, SDT10100P5 pinout, SDT10100P5 application, or SDT10100P5 equivalent, key selection criteria include low VF stability across temperature, thermal resistance (RθJC = 3°C/W on Al board), soft switching behavior, and RoHS-compliant green packaging with matte tin terminals.

Technical Context

This Schottky diode employs trench MOS structure to reduce forward voltage while maintaining tight IR control at elevated temperatures. Its 0.64–0.70 V VF range at 10 A (25–125°C) and <18 µA IR at 100 V/125°C reflect optimized metal-semiconductor interface design for high-frequency power conversion.

The PowerDI5 package enables dual thermal paths: RθJA = 18°C/W on 2"×2" aluminum board and RθJC = 3°C/W, supporting high-current operation without external heatsinking in compact DC-DC modules and adapter secondary-side rectification.

FAQ

What is the maximum recommended PCB copper area for optimal thermal performance?

The SDT10100P5 achieves its specified RθJC = 3°C/W when the cathode thermal pad is soldered to a minimum 2"×2" (50 mm × 50 mm) aluminum board or ≥100 mm² of 2-oz copper on FR-4. Smaller copper areas increase RθJA significantly-e.g., 1"×1" FR-4 yields ~88°C/W per datasheet Note 6.

Does SDT10100P5 have a specified reverse recovery time (trr)?

No-Schottky diodes like the SDT10100P5 are majority-carrier devices with no minority-carrier storage, so trr is not defined. Instead, datasheet Figure 2 confirms soft, fast switching via near-zero reverse recovery charge (Qrr ≈ 0), verified by absence of tail current in oscilloscope waveforms at 500 kHz.

Can SDT10100P5 replace a standard silicon PN rectifier in an existing design?

Yes-if the original design uses a 100 V/10 A PN diode (e.g., 10BQ100), SDT10100P5 reduces forward loss by ~0.4 V at 10 A, cutting conduction loss by ~4 W. However, verify that reverse voltage transients remain below 100 V, as Schottky devices have lower VRRM margin than PN counterparts.

Is the PowerDI5 package compatible with standard SMT reflow profiles?

Yes-the PowerDI5 package is qualified for JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak reflow temperatures up to 260°C. Its matte tin finish ensures compatibility with both leaded and lead-free solder pastes, and the 0.85 mm nominal lead height prevents tombstoning during placement.
