Product details
Overview
SDT5H100P5-7D from Diodes Incorporated is a 100 V, 5 A trench Schottky barrier rectifier in PowerDI5 package, featuring 0.62 V max forward voltage at 5 A and 0.1 mA 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 where low conduction loss and thermal stability are critical.
For engineers reviewing the SDT5H100P5-7D datasheet, SDT5H100P5-7D pinout, SDT5H100P5-7D application, or SDT5H100P5-7D equivalent, key selection criteria include VF vs. temperature performance, RθJA under defined PCB layouts (88 °C/W on FR-4, 18 °C/W with heatsink), and soft-switching behavior for EMI-sensitive power stages.
Technical Context
This Schottky rectifier uses trench MOS-enhanced architecture to achieve lower VF than planar Schottkys while maintaining tight IR control up to +125°C (20 mA max at 100 V). Its soft, fast switching minimizes voltage overshoot during diode recovery in synchronous buck and flyback topologies.
The device is rated for 150 A non-repetitive surge current (8.3 ms), supports continuous operation from –55°C to +150°C, and delivers stable forward conduction across ambient temperatures up to 125°C with derated average current per Figure 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V and 60 V bus applications. |
| IO | 5 A - Average rectified output current at TA = +25°C; usable up to ~3.2 A at +85°C per derating curve. |
| VF Max | 0.62 V @ 5 A, 25°C - Low conduction loss enables >95% efficiency in 12 V → 5 V/3.3 V point-of-load converters. |
| IR Max | 0.1 mA @ 100 V, 25°C - Tight leakage ensures minimal standby power loss in always-on adapter designs. |
| RθJA | 88 °C/W (FR-4, 2 oz Cu) - Thermal resistance determines junction rise above ambient; requires ≥100 mm² copper pour for full 5 A rating. |
| IFSM | 150 A (8.3 ms) - Withstands inrush and transient overloads typical in offline SMPS startup and load-dump events. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed cathode pad; dimensions 3.966 × 6.51 × 1.10 mm (L × W × H); UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry terminal; connected to input/source side of rectification path. |
| Pin 2 | Cathode (Exposed Pad) | Primary current exit and thermal interface; must be soldered to large copper area for heat dissipation. |
| Pin 3 | Anode | Second anode terminal; paralleled internally with Pin 1 to reduce package inductance and improve current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables 0.62 V VF at 5 A while suppressing IR drift at high TJ - improves efficiency retention in compact, sealed enclosures. |
| Soft, fast switching | Minimizes reverse recovery dv/dt and associated EMI; eliminates need for snubbers in 300–500 kHz DC-DC designs. |
| PowerDI5 thermal design | Exposed cathode pad reduces RθJA by >75% vs. SOD-123; enables 5 A operation without external heatsink on adequate PCB copper. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb); meets EU RoHS 3 and JEDEC MSL-1 requirements. |
Applications
| DC-DC Converters | AC-DC Adapters |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 300–500 kHz isolated buck-derived topologies. IC Role / Device Role: Freewheel diode replacing MOSFET gate drive complexity in cost-sensitive 5–24 V outputs. Use Value: 0.62 V VF cuts conduction loss by ~35% vs. standard silicon diodes, improving full-load efficiency by 1.2–1.8%. |
Use Scenario: Output rectification in universal-input (90–264 VAC) 12 V/5 A wall adapters. IC Role / Device Role: Primary output blocking diode handling continuous 5 A with low thermal rise in confined plastic housings. Use Value: Stable 0.1 mA IR at 25°C and only 20 mA at 125°C prevents standby power creep in Energy Star Level VI designs. |
| Industrial Power Supplies | Telecom Rectifier Modules |
Use Scenario: Input-stage OR-ing diode in redundant 24 V/48 V DC distribution systems. IC Role / Device Role: Blocking diode preventing backfeed between parallel supplies; operates continuously at 4 A ambient. Use Value: 150 A IFSM withstands hot-swap transients; RθJA = 18 °C/W with heatsink maintains TJ < 125°C under full load. |
Use Scenario: Intermediate bus rectification in -48 V telecom systems with 100 V isolation margin. IC Role / Device Role: High-reliability output rectifier in distributed power architecture (DPA) modules. Use Value: 100 V VRRM provides 2× safety margin over nominal -48 V rail; MSL-1 rating ensures robust reflow yield. |
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 100 V/5 A rating; VF = 0.65 V @ 5 A/25°C; higher IR (0.25 mA @ 100 V/25°C). | Slightly lower efficiency at full load; less stable leakage above 85°C limits use in sealed telecom enclosures. | Prefer when legacy footprint compatibility with SMB package is required; not drop-in for PowerDI5 layout. |
| ON Semiconductor SB5100 | 100 V/5 A; VF = 0.85 V @ 5 A/25°C; higher RθJA (110 °C/W on FR-4); no trench structure. | Higher conduction loss reduces efficiency by ~2.5% at full load; thermal derating begins earlier (~70°C). | Select only if cost is primary constraint and thermal margin exceeds 25°C; avoid in space-constrained or high-ambient designs. |
Compared with VSS5100-M3/5AT and SB5100, SDT5H100P5-7D delivers superior thermal stability and lowest VF in its class, enabling higher power density in thermally constrained DC-DC and adapter designs without sacrificing reliability or RoHS compliance.

FAQ
What is the maximum continuous forward current at +100°C ambient?
Per the Forward Current Derating Curve (Figure 4), SDT5H100P5-7D supports approximately 3.8 A at TA = +100°C when mounted on an FR-4 PCB with 2 oz copper and minimum recommended pad layout. This assumes natural convection cooling and no additional heatsinking.
Does SDT5H100P5-7D require a thermal pad connection for rated current operation?
Yes - the exposed cathode pad (Pin 2) must be soldered to a minimum 100 mm² copper area on the PCB to achieve the rated 5 A IO at +25°C. Without this thermal path, junction temperature rises rapidly, triggering premature derating and potential thermal runaway.
Is SDT5H100P5-7D suitable for automotive applications?
No - SDT5H100P5-7D is not AEC-Q101 qualified and lacks automotive-specific qualification testing (e.g., HTOL, TCT, ESD). It is intended for industrial, computing, and consumer power applications meeting commercial-grade reliability requirements.
How does the soft switching characteristic affect EMI in high-frequency designs?
The soft, fast switching reduces reverse recovery dv/dt by limiting stored charge (QRR < 25 nC typical), which suppresses high-frequency ringing and common-mode noise. This allows simpler EMI filter designs in 300–600 kHz DC-DC converters without added snubbers or ferrite beads.
