Product details
Overview
SDM8M100P5 from Diodes Incorporated is a single silicon Schottky barrier rectifier in PowerDI5 package, rated for 100 V peak reverse voltage, 8 A average forward current, and 0.85 V max forward voltage at 8 A and +25°C. It delivers low conduction loss and stable <1.5 µA reverse leakage at 100 V and +25°C, enabling high-efficiency DC/DC output rectification in automotive power modules.
For engineers reviewing the SDM8M100P5 datasheet, SDM8M100P5 pinout, SDM8M100P5 application, or SDM8M100P5 equivalent, key selection criteria include thermal resistance (RθJC = 3 °C/W), +175°C maximum junction temperature, soft fast switching behavior, and compatibility with high-temperature PCB layouts requiring minimal heatsinking.
Technical Context
This Schottky diode uses a planar metal–semiconductor junction optimized for low VF and controlled reverse recovery. Its 3 °C/W junction-to-case thermal resistance enables direct mounting to copper pour or heatsinked pads without thermal vias in 8 A continuous operation.
The device exhibits <0.74 V typical VF at 8 A and +125°C, and maintains <2.0 µA IR at 100 V and +125°C - critical for maintaining efficiency in under-hood automotive power supplies where ambient temperatures exceed 105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V DC or peak AC reverse voltage without breakdown |
| IO (AV) | 8 A - supports continuous forward current up to 8 A at +25°C ambient with appropriate PCB copper area |
| VF Max | 0.85 V @ 8 A, +25°C - minimizes conduction loss in high-current output stages |
| IR Max | 1.5 µA @ 100 V, +25°C - ensures low standby power loss in polarity protection circuits |
| RθJC | 3 °C/W - enables efficient heat transfer from die to PCB copper or heatsink |
| TJ Max | +175°C - supports operation in engine control units and under-dash power converters |
| CJ | 168 pF @ 4 V, +25°C - limits capacitive loading in high-frequency switching nodes |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed copper heat sink pad on bottom side; terminals are matte tin-annealed over copper leadframe; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; must be connected to PCB copper pour for thermal management |
| Right Pin | Cathode | Current exit terminal; electrically tied to exposed heat sink pad on bottom side |
| Bottom Pad | Thermal Heat Sink / Cathode Extension | Exposed copper pad provides primary thermal path; soldered directly to PCB ground or power plane |
Key Features
| Feature | Design Value |
|---|---|
| Low Forward Voltage Drop | 0.73 V typ @ 4 A, +25°C - reduces I²R losses by >30% vs. standard PN rectifiers at same current |
| +175°C Operating Junction Temperature | Rated for full electrical performance up to TJ = +175°C - eliminates derating in sealed automotive enclosures |
| Soft, Fast Switching Capability | No reverse recovery tail current - prevents voltage overshoot and EMI in synchronous buck freewheel paths |
| Lead-Free & Halogen-Free "Green" Construction | RoHS 3 compliant with <900 ppm Br/Cl and <1000 ppm Sb - meets automotive ELV and OEM chemical restrictions |
Applications
| Automotive Engine Control Unit (ECU) Power Supply | Industrial DC/DC Converter Output Rectification |
|---|---|

Use Value: Soft switching behavior suppresses voltage spikes >40 V, eliminating need for TVS clamping in cost-sensitive designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBR8M100P5 | Same PowerDI5 package, but higher VF (0.89 V max @ 8 A) and higher IR (3.0 µA @ 100 V, +25°C) | Lower efficiency in high-temp environments; not recommended for new designs per Diodes' notice | Select only for legacy board reuse where SDM8M100P5 is unavailable |
| SS8P10L | 8 A/100 V Schottky in PowerDI5; VF = 0.79 V max @ 8 A, +25°C; RθJC = 4.5 °C/W | Higher thermal resistance requires larger PCB copper area for same power dissipation | Prefer when sourcing flexibility is prioritized over minimal thermal footprint |
Compared with SBR8M100P5 and SS8P10L, SDM8M100P5 offers the lowest VF and best thermal resistance - making it optimal for space-constrained, high-temperature automotive power rails where efficiency and reliability are co-prioritized.

FAQ
Is SDM8M100P5 qualified to AEC-Q101?
No - the SDM8M100P5 is not AEC-Q101 qualified. Diodes Incorporated explicitly states that automotive-grade parts meeting AEC-Q101 require specific change control, PPAP capability, and IATF 16949 manufacturing certification. Customers needing AEC-Q101 compliance should contact Diodes directly for qualified alternatives such as the SBR8M100Q5.
What is the recommended PCB pad layout for thermal performance?
Diodes specifies a minimum 10 mm² exposed copper pad connected to internal ground/power planes via ≥4 thermal vias (0.3 mm diameter, spaced ≤2 mm apart). The suggested layout includes 1.84 mm center-to-center spacing between left and right pins, with 3.054 mm pad width for the cathode-side terminal per the PowerDI5 outline drawing.
Can SDM8M100P5 replace a standard PN junction rectifier in existing designs?
Yes - it can replace PN rectifiers like 1N5408 or MUR8100 in most cases, provided layout accommodates the PowerDI5 footprint and thermal path. Key advantages include lower VF (reducing heat generation) and zero reverse recovery charge, but note its lower reverse voltage margin (100 V vs. 1000 V for MUR8100), so verify system transient requirements.
Why is SDM8M100P5 marked "Not Recommended for New Design" alongside SBR8M100P5?
That marking applies only to SBR8M100P5, not SDM8M100P5. The datasheet clearly labels SBR8M100P5 as "NOT RECOMMENDED FOR NEW DESIGN" due to obsolescence planning. SDM8M100P5 remains the active, preferred replacement with improved VF and IR specs, and is fully supported for new designs.
