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 delivers soft, fast switching for DC-DC converter output rectification.
For engineers reviewing the SDT8A100P5 datasheet, SDT8A100P5 pinout, SDT8A100P5 application, or SDT8A100P5 equivalent, key selection criteria include low VF stability across temperature, thermal resistance (RθJC = 3°C/W on Al substrate), reverse leakage behavior at 125°C, and compatibility with high-density power supply layouts using the 3.966 mm × 6.51 mm PowerDI5 footprint.
Technical Context
This Schottky rectifier uses trench MOS structure to reduce forward voltage while maintaining low reverse leakage-critical for high-efficiency 12 V/48 V intermediate bus converters. Its RθJC of 3°C/W on 2″×2″ aluminum PCB enables sustained 8 A conduction without forced air cooling.
The device exhibits soft recovery with negligible reverse recovery charge (Qrr), eliminating snubber circuits in synchronous buck secondary-side rectification. Reverse leakage remains ≤20 µA at 125°C and 100 V, supporting stable operation in thermally constrained industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands continuous DC blocking up to 100 V in AC-DC adapters and PoE injectors |
| IO (AV) | 8 A - Sustains full-load current in 60–100 W DC-DC converters without derating at TC ≤ 85°C |
| VF (max) | 0.70 V @ 8 A, 25°C - Reduces conduction loss by ≥15% vs. planar Schottky diodes in 12 V output rails |
| IR (max) | 0.1 mA @ 100 V, 25°C - Ensures minimal standby power loss in energy-efficient power supplies |
| TJ range | −55°C to +150°C - Supports operation in automotive under-hood and industrial motor drive environments |
| RθJC | 3°C/W - Enables direct thermal coupling to heatsinked PCBs for compact 8 A rectifier designs |
Pinout & Package

| High-temperature leakage stability | IR ≤ 20 µA at 125°C/100 V prevents thermal runaway in enclosed power modules |
| Soft, fast switching | Negligible Qrr eliminates voltage spikes during turn-off, reducing EMI filter size in Class B designs |
| +150°C junction rating | Enables use in sealed enclosures with ambient temperatures up to +85°C without airflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V8P10HM3/H | Same 100 V/8 A rating; VF = 0.72 V @ 8 A; RθJC = 4.5°C/W; TO-277 package | Larger footprint (6.7 mm × 4.2 mm) and higher thermal resistance limit power density | Select when legacy TO-277 layout reuse is required; avoid in space-constrained designs |
| ON Semiconductor SB8100 | 100 V/8 A; VF = 0.75 V @ 8 A; RθJC = 5.0°C/W; PowerFLAT 5×6 package | Higher VF increases conduction loss by 0.12 W; larger thermal pad area needed for equivalent cooling | Prefer only if PowerFLAT 5×6 footprint already standardized; inferior thermal performance vs. PowerDI5 |
Compared with V8P10HM3/H and SB8100, SDT8A100P5 delivers lowest thermal resistance (3°C/W) and tightest VF spec (0.70 V), enabling higher power density in compact DC-DC converters where board area and thermal headroom are constrained.

FAQ
What is the maximum continuous forward current for SDT8A100P5 at 100°C case temperature?
At TC = 100°C, SDT8A100P5 supports 5.2 A average forward current per Figure 4 derating curve. This is determined by its RθJC = 3°C/W and thermal limit of +150°C junction temperature, ensuring safe operation without exceeding TJ(max) under natural convection on aluminum substrate.
Does SDT8A100P5 require a heatsink in standard FR-4 PCB applications?
No external heatsink is required when mounted on FR-4 with minimum recommended pad layout (2 oz copper, 200 mm² thermal pad). At 8 A and TA = 25°C, junction temperature reaches ~115°C-within the +150°C rating-due to RθJA = 18°C/W on optimized PCB.
Is SDT8A100P5 qualified for automotive applications per AEC-Q101?
SDT8A100P5 is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., SDT8A100Q5) with PPAP documentation and IATF 16949 manufacturing; this part is intended for industrial and commercial power supplies only.
How does the PowerDI5 package improve thermal performance over SMC or SMA packages?
PowerDI5's exposed cathode pad provides direct thermal path to PCB copper, achieving RθJC = 3°C/W-up to 60% lower than SMA (RθJC ≈ 7.5°C/W). Its 3.966 mm × 6.51 mm footprint also allows tighter layout spacing than SMC (7.11 mm × 6.22 mm), increasing power density in multi-rail converters.
