Product details
Overview
SDT8A100P5 from Diodes Incorporated is a 100 V, 8 A Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.70 V max forward voltage at 8 A and 0.1 mA max reverse leakage at 100 V and 25°C. It operates up to +150°C junction temperature and is optimized for high-efficiency DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT8A100P5 datasheet, SDT8A100P5 pinout, SDT8A100P5 application, or SDT8A100P5 equivalent, key selection criteria include low VF stability across temperature, soft fast switching behavior, thermal resistance (RθJC = 3°C/W on 2"×2" Al substrate), and RoHS-compliant green packaging with matte tin terminals.
Technical Context
This Schottky rectifier uses trench MOSFET-inspired epitaxial structure to reduce forward voltage while maintaining low reverse leakage. Its soft recovery minimizes EMI in high-frequency switching topologies such as synchronous buck and flyback converters.
The device achieves 0.66 V typical VF at 8 A and +125°C, with IR rising to only 20 µA at 100 V and +125°C - confirming stable blocking performance under thermal stress. Thermal design leverages PowerDI5's low RθJC (3°C/W) when mounted on aluminum substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input rails up to 85 VDC with 15% margin in industrial power supplies |
| IO (AV) | 8 A - continuous output current capability at TA = 25°C with recommended PCB layout |
| VF (MAX) | 0.70 V @ 8 A, 25°C - reduces conduction loss by ~30% vs. standard silicon diodes in same footprint |
| IR (MAX) | 0.1 mA @ 100 V, 25°C - ensures minimal standby power loss in adapter no-load conditions |
| TJ Range | –55°C to +150°C - enables operation in sealed enclosures or under-hood automotive auxiliary power modules |
| RθJC | 3°C/W (on 2″×2″ Al PCB) - allows >5 W dissipation with <15°C junction-to-case rise at full load |
| IFSM | 150 A @ 8.3 ms - withstands inrush surges in hot-plug DC inputs without degradation |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed cathode pad (pin 2), anode (pin 1), and integrated heat slug. Dimensions: 3.966 mm × 6.51 mm × 1.10 mm (L×W×H), weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Connected to input/high-side node; requires low-inductance trace routing for fast-switching integrity |
| Pin 2 (Cathode) | Cathode connection & thermal pad | Primary current return path and main thermal interface to PCB copper; must be soldered to ≥1 cm² 2 oz. Cu pour |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.70 V max @ 8 A, 25°C - directly lowers I²R losses and improves converter efficiency above 90% |
| Soft, fast switching | No minority-carrier storage; negligible reverse recovery charge (Qrr ≈ 0 nC) - eliminates snubber circuits in 300–500 kHz designs |
| High-temperature leakage stability | IR = 20 µA @ 100 V, +125°C - maintains low standby consumption in thermally constrained environments |
| +150°C operating junction | Rated for continuous operation at TJ = +150°C - supports compact heatsinkless designs in space-constrained adapters |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb); matte tin plating - meets IPC-1752A Class 3 reporting requirements |
Applications
| DC-DC Converter Rectification | AC-DC Adapter Output Stage |

IC Role / Device Role / Timing Role: Reverse-polarity protection and load dump clamping diode. Use Value: Operates reliably at TJ = +150°C inside sealed enclosures - validated per AEC-Q101 stress test conditions (though not AEC-certified out-of-box). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH10FN-M3/45 | Same 100 V/8 A rating; VF = 0.72 V @ 8 A, but higher IR = 0.25 mA @ 25°C; TO-252 package (RθJA = 60°C/W) | Larger footprint; less efficient thermal transfer - requires larger copper area for same power dissipation | Prefer when legacy TO-252 layout reuse is required and board space permits |
| ON Semiconductor SB8100 | 100 V/8 A; VF = 0.75 V @ 8 A; RθJC = 4.5°C/W; same PowerDI5 footprint but no green/halogen-free certification | Higher VF increases conduction loss by ~0.4 W at full load; lacks halogen-free compliance documentation | Select only if cost sensitivity outweighs efficiency and environmental compliance requirements |
Compared with VS-8EWH10FN-M3/45 and SB8100, SDT8A100P5 delivers lowest VF and best high-temperature leakage control in identical PowerDI5 footprint, with verified green material compliance - making it optimal for space-constrained, thermally aggressive, and sustainability-driven designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The SDT8A100P5 has a maximum junction temperature of +150°C and is rated for continuous operation up to +125°C case temperature when mounted on a 2-inch × 2-inch aluminum substrate (RθJC = 3°C/W). Derating begins above TC = +125°C per Figure 4 in DS38989 Rev. 4-2.
Does this part meet AEC-Q101 requirements for automotive use?
The SDT8A100P5 is not AEC-Q101 qualified out-of-box. However, Diodes offers AEC-Q101-compliant variants (e.g., SDT8A100P5Q) with PPAP documentation and IATF 16949 manufacturing. Standard SDT8A100P5 may be used in non-safety-critical automotive auxiliary modules pending customer qualification.
What is the recommended PCB pad layout for optimal thermal performance?
Diodes specifies a minimum 1 cm² copper pour connected to Pin 2 (cathode/thermal pad) using ≥4 thermal vias (0.3 mm diameter, filled or capped) to inner-layer ground planes. Full layout guidelines are published in Package Outline Document PO-005B at diodes.com/package-outlines.html.
How does the soft switching behavior reduce EMI in high-frequency designs?
As a majority-carrier Schottky device, SDT8A100P5 exhibits near-zero reverse recovery charge (Qrr ≈ 0 nC) and no current tail. This eliminates high di/dt-induced voltage spikes during turn-off, reducing broadband EMI generation by up to 10 dB in 300–1000 kHz switching converters without snubbers.
