Product details
Overview
SDT5H100LP5-7D from Diodes Incorporated is a 100 V, 5 A trench Schottky barrier rectifier in PowerDI5 package, featuring 0.66 V max forward voltage at 5 A and 3.5 µA max reverse leakage at 100 V/25°C. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT5H100LP5-7D datasheet, SDT5H100LP5-7D pinout, SDT5H100LP5-7D application, or SDT5H100LP5-7D equivalent, key selection criteria include low VF stability across temperature, thermal resistance (18 °C/W with heatsink), soft switching behavior, and RoHS-compliant green packaging for compact power conversion designs.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage control versus planar Schottky devices. Its soft, fast switching minimizes EMI in high-frequency switching topologies such as synchronous buck and flyback converters.
The PowerDI5 package provides dual thermal paths-junction-to-ambient (88 °C/W on FR-4) and junction-to-heatsink (18 °C/W)-enabling higher power density than SOD-123 or SMA packages at comparable current ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 48 V and 60 V bus applications. |
| IO (AV) | 5 A - Average forward current rating at 25°C ambient; derates to ~3.5 A at 85°C ambient per Figure 4. |
| VF (max) | 0.66 V @ 5 A, 25°C - Enables <3.3 W conduction loss at full load; critical for >90% efficiency targets in 12 V–48 V outputs. |
| IR (max) | 3.5 µA @ 100 V, 25°C - Low leakage preserves standby power in always-on systems; rises to 4.5 µA at 125°C. |
| RθJA | 18 °C/W - With aluminum heatsink; allows 3.3 W dissipation with ≤60°C temperature rise above ambient. |
| TJ Range | −55 to +150°C - Supports operation in automotive under-hood and industrial motor drive environments. |
| CT | ~100 pF @ 0 V - Low junction capacitance reduces switching losses and ringing in >500 kHz converters. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed cathode pad; dimensions 4.0 × 6.5 × 0.85 mm; UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to input rail or switch node; requires low-inductance layout to minimize voltage spikes during turn-off. |
| Cathode | Output current terminal / thermal pad | Primary current output path and main thermal conduction path to PCB copper; must be soldered to ≥25 mm² 2 oz. copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~0.1 V vs. planar Schottky at 5 A, directly lowering conduction loss in high-current paths. |
| Soft, fast switching | Minimizes reverse recovery dv/dt-induced EMI; eliminates need for snubbers in 300–1000 kHz DC-DC stages. |
| Thermal resistance (RθJA = 18 °C/W) | Enables 3.3 W continuous dissipation with modest heatsinking-supports compact 12 V/5 A adapter designs without forced air. |
| Halogen- and antimony-free "Green" compound | Meets IEC 61249-2-21; contains <900 ppm Br, <900 ppm Cl, <1000 ppm Sb-complies with strict environmental mandates. |
Applications
| DC-DC Converters | AC-DC Adapters |
|---|---|
Use Scenario: Output rectification in 400 kHz synchronous buck converter delivering 12 V/5 A from 48 V input. IC Role / Device Role / Timing Role: Freewheel diode replacing body diode of low-side MOSFET; conducts during low-side FET off-time. Use Value: 0.61 V VF at 5 A/125°C reduces conduction loss by 0.5 W vs. standard Schottky, improving full-load efficiency by 0.8%. | Use Scenario: Secondary-side rectification in 65 W laptop adapter with active clamp flyback topology. IC Role / Device Role / Timing Role: Output blocking diode preventing reverse current flow during transformer reset phase. Use Value: 3.5 µA IR at 25°C ensures <1 mW standby loss; stable leakage up to 125°C maintains no-load compliance. |
| Industrial Motor Drives | Telecom Power Supplies |
Use Scenario: Brake energy recirculation path in 24 V BLDC controller with regenerative braking. IC Role / Device Role / Timing Role: Reverse-polarity protection and freewheeling path for inductive back-EMF pulses. Use Value: −55 to +150°C operating range supports unheated enclosure deployment; soft switching suppresses voltage overshoot on 40 V transients. | Use Scenario: OR-ing diode in redundant 48 V telecom rectifier module with hot-swap capability. IC Role / Device Role / Timing Role: Unidirectional current gate isolating parallel power inputs while minimizing insertion loss. Use Value: 0.55 V VF at 3 A/25°C yields <1.7 W loss per diode-critical for maintaining <20 mV droop across 100 A system bus. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS5H100FL-7 | Same VRRM (100 V), IO (5 A), but VF = 0.72 V max @ 5 A/25°C; RθJA = 22 °C/W (heatsink). | Slightly higher conduction loss; less suitable for thermally constrained 500 kHz+ designs. | Prefer SDT5H100LP5-7D where VF < 0.66 V and RθJA ≤ 18 °C/W are required. |
| MBR5H100FCT | TO-220AC package; VF = 0.69 V max @ 5 A/25°C; RθJA = 50 °C/W (no heatsink); larger footprint. | Requires mechanical mounting and heatsink; unsuitable for ultra-thin or double-sided PCBs. | Choose SDT5H100LP5-7D for surface-mount, space-constrained, or automated assembly applications. |
Compared with SS5H100FL-7 and MBR5H100FCT, SDT5H100LP5-7D delivers the lowest VF and best thermal performance in a compact SMT package-making it optimal for high-density, high-efficiency 5 A rectification where board area and thermal headroom are limited.

FAQ
What is the maximum junction temperature and how does it affect reliability?
The SDT5H100LP5-7D has a maximum junction temperature of +150°C. Operating continuously near this limit accelerates parametric drift and reduces long-term reliability; design guidelines recommend limiting TJ to ≤135°C using thermal modeling and proper PCB copper area. Derating curves in Figure 4 show usable current drops to ~3.5 A at 85°C ambient with standard FR-4 layout.
Is the PowerDI5 package compatible with standard reflow profiles?
Yes-the PowerDI5 package is qualified for lead-free reflow per J-STD-020, with moisture sensitivity level 1. Recommended peak temperature is 260°C for ≤10 seconds; preheat ramp rate ≤3°C/s; time above 217°C should be 60–150 seconds. The green molding compound remains stable under these conditions without delamination or popcorning.
How does the soft switching characteristic reduce EMI in DC-DC designs?
Soft switching refers to the absence of abrupt reverse recovery current (Irr) and low di/dt during turn-off. In SDT5H100LP5-7D, this eliminates high-frequency ringing caused by parasitic L-C oscillation between circuit inductance and diode junction capacitance-reducing conducted EMI by 5–10 dB in the 30–100 MHz band without added snubbers or ferrites.
Can SDT5H100LP5-7D replace older Schottky diodes like SB5100 in existing designs?
Yes, with validation: SDT5H100LP5-7D matches SB5100's 100 V/5 A rating but improves VF by ~0.15 V and offers superior high-temperature leakage stability. Layout adaptation is required due to PowerDI5's different footprint and thermal pad requirements; thermal simulation is recommended to confirm junction temperature remains within spec under identical operating conditions.
