Product details
Overview
SDT15H100P5 from Diodes Incorporated is a 15A, 100V Trench Schottky Barrier Rectifier in PowerDI5 package, featuring 0.66V max forward voltage at 15A/25°C and 250µA max reverse leakage at 100V/25°C. It serves as a high-efficiency rectifier, freewheel diode, or blocking diode in compact DC/DC converters and AC/DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT15H100P5 datasheet, SDT15H100P5 pinout, SDT15H100P5 application, or SDT15H100P5 equivalent, key selection criteria include low VF stability across temperature, soft fast switching for EMI reduction, thermal resistance (RθJC = 3°C/W on heatsink), and RoHS-compliant green packaging with 12mm tape & reel delivery.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and superior high-temperature leakage control versus planar Schottky devices. Its soft recovery minimizes voltage ringing during turn-off in synchronous buck and flyback topologies.
The PowerDI5 package enables dual thermal paths: 14°C/W RθJA on aluminum heatsink PCB and 90°C/W on standard FR-4, supporting high-power density designs where case-to-heatsink conduction dominates thermal management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V15PM10-M3/86A | Same 100V/15A rating but higher VF (0.72V max @ 15A) and larger TO-277 package | Lower thermal performance (RθJC = 5.5°C/W); requires larger PCB area | Prefer when legacy TO-277 footprint compatibility is required over thermal density |
| ON Semiconductor SB15100L | Lower IF rating (10A), same VF spec, PowerDI5 package, but only rated to +125°C TJ | Not suitable for sustained +150°C environments; limited surge robustness (IFSM = 200A) | Select only for cost-sensitive consumer adapters with ambient <60°C and no thermal margin constraints |
Compared with V15PM10-M3/86A and SB15100L, SDT15H100P5 delivers superior thermal efficiency (3°C/W RθJC), extended temperature capability (+150°C), and lower conduction loss-making it optimal for space-constrained, high-reliability industrial and telecom power designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The SDT15H100P5 has a maximum junction temperature of +150°C and a typical RθJC of 3°C/W on an aluminum heatsink. Using the derating curve in Figure 4, continuous operation at 15A requires TC ≤ +115°C to maintain TJ ≤ +150°C. For FR-4 PCBs (RθJA = 90°C/W), ambient must be kept below +45°C at full load.
Is the PowerDI5 package lead-free and halogen-free?
Yes. The SDT15H100P5 features a lead-free finish compliant with RoHS 2 (2011/65/EU) and is halogen- and antimony-free per Diodes' "Green" definition: <900ppm bromine, <900ppm chlorine (total Br+Cl <1500ppm), and <1000ppm antimony compounds.
How does the dual-anode configuration improve performance?
The PowerDI5's Pin 1 and Pin 3 are both anodes, providing two parallel current paths that reduce effective series resistance and trace inductance. This lowers conduction loss and improves high-frequency transient response-especially beneficial in multi-phase or high-di/dt synchronous rectifier layouts.
Can SDT15H100P5 replace older Schottky diodes like SB15100 in existing designs?
Yes, with qualification. While pin-compatible in PowerDI5 footprint, SDT15H100P5 offers lower VF (0.66V vs. 0.75V typical), better high-temperature leakage (250µA vs. 500µA at 125°C), and +150°C rating vs. +125°C. Thermal validation and surge testing are recommended before drop-in replacement in mission-critical systems.
