Product details

Overview

SDT5A100P5-13D from Diodes Incorporated is a 5A, 100V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.66V max forward voltage at 5A/25°C, 50µA max reverse leakage at 100V/25°C, and 150°C maximum junction temperature - deployed as freewheel or output rectifier in DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT5A100P5-13D datasheet, SDT5A100P5-13D pinout, SDT5A100P5-13D application, or SDT5A100P5-13D equivalent, key selection criteria include low VF stability across -55°C to +150°C, soft-switching behavior for EMI reduction, thermal resistance of 3°C/W (junction-to-case), and compatibility with high-density PCB layouts using 12mm tape on 13-inch reel.

Technical Context

This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and reduced reverse recovery charge versus planar Schottkys. Its soft, fast switching minimizes voltage overshoot during diode turn-off in synchronous buck topologies.

The device operates up to 150°C junction temperature with stable IR <15µA at 100V/125°C, enabled by optimized metal-semiconductor interface and low R_θJC (3°C/W) when mounted on an aluminum heatsink per Note 7.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MBR5100FCT-ND (ON Semi)	5A/100V, VF = 0.75V @ 5A, 25°C; TO-220AC package; R_θJC = 4°C/W	Requires through-hole mounting and heatsink; higher VF increases conduction loss by ~140mW at 5A	Preferred where board space permits discrete heatsinking and legacy TO-220 footprint is required
SS5P10 (Vishay)	5A/100V, VF = 0.69V @ 5A, 25°C; PowerPAK SO-8 package; R_θJC = 4.5°C/W	SO-8 footprint lacks exposed thermal pad; limited to ≤3.5A continuous in same PCB layout	Selected when existing SO-8 layout must be reused and peak current stays below 3.5A

Compared with MBR5100FCT-ND and SS5P10, SDT5A100P5-13D delivers lowest VF and best thermal performance in compact surface-mount form, enabling higher power density in space-constrained DC-DC modules without sacrificing efficiency or thermal margin.

FAQ

What is the recommended PCB pad layout for optimal thermal performance?

For R_θJC = 3°C/W, Diodes specifies a minimum 50mm × 50mm × 23mm aluminum heatsink attached to the exposed pad via ≥25 mm² copper pour on 2oz FR-4. The pad layout must follow the PowerDI5 outline in DS40875 Figure 6, including thermal vias spaced ≤1.2mm apart under the pad to inner-layer copper planes.

Does SDT5A100P5-13D support reflow soldering per JEDEC J-STD-020?

Yes - the device is rated Moisture Sensitivity Level 1 (MSL-1), meaning it may be stored indefinitely at ≤30°C/60% RH and subjected to standard Pb-free reflow profiles (peak 260°C, 30 sec max above 217°C) without baking or special handling.

How does its soft switching behavior reduce EMI in high-frequency converters?

Unlike abrupt-recovery diodes, the SDT5A100P5 exhibits gradual reverse recovery with near-zero reverse recovery charge (Q_rr), minimizing high-frequency ringing at switch-node nodes. This reduces conducted EMI in 500kHz–2MHz buck converters, easing compliance with CISPR-22 Class B limits.

Is the 100V V_RRM rating sufficient for use in 48V input DC-DC converters?

Yes - the 100V rating provides 2× safety margin over nominal 48V input (including 100V transients per ISO 7637-2 Pulse 1/2), and remains valid up to 150°C junction temperature, ensuring reliable blocking during cold-crank or load-dump events in automotive auxiliary supplies.
