Product details
Overview
SDT5H100LP5-13 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 / 25°C 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 SDT5H100LP5-13 datasheet, SDT5H100LP5-13 pinout, SDT5H100LP5-13 application, or SDT5H100LP5-13 equivalent, key selection criteria include thermal resistance (18 °C/W with heatsink), soft fast switching behavior, low VF stability across temperature, and RoHS-compliant green packaging for high-reliability 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 100 V VRRM rating supports 48 V and 36 V bus applications with margin, while 150 A non-repetitive surge capability handles transient load dumps.
The PowerDI5 package enables dual thermal paths-junction-to-ambient (88 °C/W on FR-4) and junction-to-heatsink (18 °C/W)-making it suitable for compact, thermally constrained layouts where solder-side copper and external heatsinking are leveraged.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports 48 V nominal input systems with 2× safety margin against transients |
| IO (AV) | 5 A - continuous DC output current handling in buck/boost converter outputs |
| VF Max | 0.66 V @ 5 A, 25°C - reduces conduction loss by ~15% vs. comparable 0.78 V Si diodes |
| IR Max | 3.5 µA @ 100 V, 25°C - ensures minimal standby power loss in always-on adapter circuits |
| RθJA | 18 °C/W with Al heatsink - enables 3.3 W dissipation at ≤50°C ambient rise in thermally optimized layout |
| TJ Range | −55 to +150°C - qualified for under-hood automotive and industrial ambient environments |
| IFSM | 150 A @ 8.3 ms - withstands inrush and short-circuit events without bond wire failure |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed cathode pad; dimensions 3.966 mm × 6.504 mm × 0.85 mm; UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to switch node or transformer secondary; requires low-inductance routing to minimize ringing |
| Cathode | Output current terminal | Exposed metal pad - must be soldered to ≥200 mm² copper pour for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables 0.48 V VF at 3 A / 125°C - maintains efficiency in high-temp DC-DC stages |
| Soft, fast switching | Low reverse recovery charge (QRR < 15 nC typical) - minimizes EMI in 300–1000 kHz SMPS |
| Thermally optimized PowerDI5 | 18 °C/W RθJH enables >3 W continuous dissipation with 50 mm × 50 mm heatsink |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - meets IPC-1752A Tier 2 reporting |
Applications
| DC-DC Converter Output Rectification | AC-DC Adapter Secondary Side |
|---|---|
Use Scenario: Synchronous or asynchronous buck converter output stage delivering 3.3 V/5 V/12 V at up to 5 A. IC Role / Device Role / Timing Role: Freewheeling rectifier conducting during low-side switch off-time; defines minimum on-time and efficiency floor. Use Value: 0.66 V VF reduces conduction loss by 0.33 W vs. 1.0 V Si diode at 5 A - directly improves full-load efficiency by 1.2% in 12 V → 5 V conversion. | Use Scenario: Secondary-side rectification in 12–24 W wall-mounted AC-DC adapters powering IoT gateways or set-top boxes. IC Role / Device Role / Timing Role: Output blocking diode preventing backfeed from bulk capacitor into transformer during no-load conditions. Use Value: 3.5 µA IR at 25°C and <4.5 µA at 125°C ensures <1 mW standby loss - critical for meeting DOE Level VI and EU CoC v5 requirements. |
| Industrial 48 V DC Power Distribution | Automotive Body Control Module Supply |
Use Scenario: Point-of-load (POL) rectification in 48 V server rack power distribution units feeding 12 V intermediate bus converters. IC Role / Device Role / Timing Role: High-current blocking diode isolating downstream converters during fault conditions or hot-swap events. Use Value: 150 A IFSM rating supports 48 V bus fault currents without catastrophic failure - enables robust system-level fault containment. | Use Scenario: Input rectification for 12 V supply rail in body control modules exposed to under-hood temperatures up to +105°C ambient. IC Role / Device Role / Timing Role: Reverse polarity protection and battery feed isolation diode in always-on subsystems. Use Value: Stable VF and IR up to +150°C TJ ensures consistent dropout and leakage behavior - eliminates thermal runaway risk in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSS5100M3/H | Same 100 V/5 A rating; VF = 0.69 V @ 5 A/25°C; RθJA = 22 °C/W (heatsink); no trench structure | Slightly higher conduction loss; less stable IR above 100°C | Preferred where legacy qualification or second-source validation is required |
| ON Semiconductor SB5100 | DO-201AD package; VF = 0.85 V @ 5 A/25°C; RθJA = 50 °C/W; 125°C max TJ | Larger footprint; higher thermal resistance limits power density; lower temp rating | Only suitable for low-power, non-thermally constrained designs with ample board area |
Compared with VSS5100M3/H and SB5100, SDT5H100LP5-13 delivers superior thermal performance (18 °C/W), lower VF (0.66 V), and extended temperature operation (150°C), making it optimal for space-constrained, high-efficiency, and high-ambient applications where power density and reliability are prioritized.

FAQ
What is the maximum recommended PCB copper area for optimal thermal performance of SDT5H100LP5-13?
The datasheet specifies a 2 oz. copper FR-4 layout with minimum pad dimensions per Diodes' package outline AP02005. For 18 °C/W thermal resistance, a 50 mm × 50 mm aluminum heatsink mounted to the cathode pad is required. Without heatsink, 200 mm² of 2 oz. copper on both sides with thermal vias yields ~88 °C/W.
Does SDT5H100LP5-13 support synchronous rectification topologies?
No - SDT5H100LP5-13 is a unidirectional Schottky rectifier, not a MOSFET-based synchronous device. It functions only as a passive freewheeling or blocking diode. For synchronous rectification, discrete N-channel MOSFETs or dedicated SR controllers (e.g., AP3410) must be used in conjunction with gate drive circuitry.
Is the PowerDI5 package lead-free and halogen-free per JEDEC standards?
Yes - SDT5H100LP5-13 features a lead-free finish compliant with RoHS 2 (2011/65/EU) and is halogen- and antimony-free per Diodes' "Green" definition: <900 ppm bromine, <900 ppm chlorine (≤1500 ppm total Br+Cl), and <1000 ppm antimony compounds.
Can SDT5H100LP5-13 replace older DO-214AB Schottky diodes in existing designs?
Yes - with board layout revision. The PowerDI5 footprint differs from DO-214AB: smaller (3.97 × 6.50 mm vs. 6.73 × 7.24 mm), different pad geometry, and exposed cathode thermal pad. Thermal and electrical performance improves, but mechanical compatibility requires redesign of solder mask and copper pads per AP02005.
