Diodes Incorporated SDT10A100P5-7

Overview

SDT10A100P5 from Diodes Incorporated is a 10A, 100V trench Schottky barrier rectifier in PowerDI5 package, featuring 0.68V max forward voltage at 10A/25°C, 100µA max reverse leakage at 100V/25°C, and 150°C maximum junction temperature. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT10A100P5 datasheet, SDT10A100P5 pinout, SDT10A100P5 application, or SDT10A100P5 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 3°C/W junction-to-case thermal resistance in PCB-mounted configuration.

Technical Context

This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage performance versus planar Schottky diodes. Its soft recovery minimizes voltage overshoot during turn-off, reducing snubber requirements in flyback and synchronous rectification topologies.

The device operates with 9°C/W typical R_θJC on FR-4 and 3°C/W on 2"×2" aluminum board, enabling high-current operation without external heatsinking in space-constrained power supplies where thermal management is critical.

FAQ

What is the maximum allowable case temperature for continuous 10A operation?

The SDT10A100P5 supports 10A average output current up to 110°C case temperature, as shown in Figure 4 of the datasheet. At higher case temperatures, current must be linearly derated to maintain T_J ≤ 150°C - e.g., 7.5A at 125°C case.

Is the PowerDI5 package lead-free and RoHS compliant?

Yes. The SDT10A100P5 features matte tin annealed terminals over copper leadframe and complies with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. It is also halogen- and antimony-free per Diodes' "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb).

Does this diode require a heatsink in standard FR-4 PCB layouts?

No external heatsink is required when mounted on a 1"×1" 2oz copper pad. With R_θJA = 88°C/W on FR-4, power dissipation remains below 1.2W at 10A (VF ≈ 0.64V), resulting in ~106°C junction rise - within the 150°C limit when ambient is ≤44°C.

How does the soft switching behavior affect EMI in high-frequency converters?

Soft switching reduces reverse recovery dv/dt and eliminates hard-edge ringing during turn-off, lowering broadband conducted EMI by 6–10dB in 300–1000kHz bands. This simplifies filter design and helps meet CISPR-32 Class B limits without additional snubbers in 500kHz+ flyback designs.
