Product details
Overview
SDT5A100P5 from Diodes Incorporated is a 5A, 100V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.66V max forward voltage at 5A and 50µA max reverse leakage at 100V/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 SDT5A100P5 datasheet, SDT5A100P5 pinout, SDT5A100P5 application, or SDT5A100P5 equivalent, key selection criteria include thermal resistance (RθJC = 3°C/W with heatsink), soft fast switching behavior, low VF stability across -55°C to +150°C, and RoHS-compliant green packaging.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage control versus planar Schottky diodes. Its 0.59V typical VF at 5A/25°C and 0.63V at 5A/125°C enables higher efficiency in compact power supplies.
The PowerDI5 package delivers RθJA = 18°C/W with heatsink and RθJC = 3°C/W, supporting 5A continuous current at case temperatures up to 100°C per derating curve. Junction capacitance is 1000pF at 4V reverse bias, enabling fast recovery without hard reverse recovery spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks full-wave rectified 70V RMS input or 100V DC bus without breakdown |
| IO | 5 A - supports continuous output current in 25–60W DC-DC stages with proper PCB copper area |
| VF Max | 0.66 V @ 5A/25°C - reduces conduction loss to ≤3.3W, critical for thermally constrained adapters |
| IR Max | 50 µA @ 100V/25°C - ensures minimal standby power loss in energy-efficient designs |
| TJ Max | +150°C - allows operation in sealed enclosures or high-ambient industrial environments |
| RθJC | 3°C/W - enables direct mounting to heatsink for sustained 5A load without thermal throttling |
| CJ | 1000 pF @ 4V - limits capacitive turn-on current and EMI in high-frequency SMPS |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed cathode pad, 0.093g mass, UL 94V-0 rated molding compound, and matte tin terminals solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSS5100-M3/5AT | Same 100V/5A rating; VF = 0.69V max @ 5A; RθJC = 4.5°C/W; PowerPAK SO-8 package | Larger footprint; requires different PCB layout; slightly higher conduction loss | Preferred when existing SO-8 footprint is fixed and thermal margin ≥5°C/W is available |
| ON Semiconductor SB5100 | 100V/5A; VF = 0.85V max @ 5A; TO-220AC package; RθJC = 4°C/W | Through-hole mounting; 3× larger board area; 30% higher conduction loss | Selected only for legacy through-hole assembly or where forced-air cooling permits higher VF penalty |
Compared with VSS5100-M3/5AT and SB5100, SDT5A100P5 delivers lowest VF and best thermal resistance in smallest footprint, making it optimal for space-constrained, high-efficiency DC-DC outputs where thermal performance directly impacts reliability.

FAQ
What is the maximum allowable case temperature for continuous 5A operation?
The SDT5A100P5 supports 5A average output current up to 100°C case temperature, as shown in Figure 5's derating curve. At 100°C TC, junction temperature remains within the +150°C absolute maximum when mounted on a 50mm × 50mm × 23mm aluminum heatsink (RθJC = 3°C/W).
Does this diode require a minimum reverse voltage to achieve specified leakage current?
No - the 50µA maximum IR is measured at full rated VRRM = 100V. Leakage increases with both voltage and temperature: typical values are 4µA at 100V/25°C and 15µA at 100V/125°C, per Electrical Characteristics table.
Can SDT5A100P5 replace a standard silicon PN rectifier in an existing design?
Yes - it can directly replace 100V/5A silicon diodes (e.g., 1N5408) with significant efficiency gain. However, verify layout compatibility: PowerDI5's exposed cathode pad requires thermal copper connection, unlike through-hole leads, and its lower VF may increase peak currents in unregulated circuits.
Is the PowerDI5 package compatible with standard reflow profiles for lead-free soldering?
Yes - the device is qualified for Pb-free reflow per J-STD-020, with moisture sensitivity level 1. Recommended peak temperature is 260°C for ≤30 seconds; preheat ramp rate ≤3°C/s and time above 217°C should be 60–150 seconds per JEDEC standards.
