Product details
Overview
SDT10A100P5-7D from Diodes Incorporated is a 10A, 100V trench Schottky barrier rectifier in PowerDI5 package, featuring 0.68V max forward voltage at 10A/25°C, 100µA max reverse leakage at 100V/25°C, and 150°C maximum junction temperature. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT10A100P5-7D datasheet, SDT10A100P5-7D pinout, SDT10A100P5-7D application, or SDT10A100P5-7D equivalent, key selection criteria include thermal resistance (RθJC = 3°C/W on 2"×2" Al board), soft switching behavior, high-temperature leakage stability (20µA at 125°C), and RoHS-compliant matte tin terminations.
Technical Context
This Schottky rectifier uses trench MOS structure to reduce forward voltage while maintaining low reverse leakage up to 150°C junction temperature. Its soft, fast switching minimizes EMI in high-frequency power supplies.
Thermal performance is optimized for surface-mount operation: RθJA is 18°C/W on 2"×2" aluminum board and 88°C/W on standard FR-4, enabling compact 10A designs without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48V–60V bus applications. |
| IO (AV) | 10 A - Average rectified current at TC = 100°C; supports continuous 10A conduction with proper heatsinking. |
| VF (max) | 0.68 V @ 10A, 25°C - Low conduction loss enables >95% efficiency in 12V-output buck converters. |
| IR (max) | 100 µA @ 100V, 25°C - Tight leakage spec ensures minimal standby power loss in energy-sensitive adapters. |
| TJ (max) | +150°C - Enables reliable operation in sealed enclosures or high-ambient industrial environments. |
| RθJC | 3 °C/W - Low junction-to-case resistance allows direct thermal coupling to metal-core PCBs or heatsinks. |
| IFSM | 240 A @ 8.3ms - Withstands typical inrush surges in offline SMPS without degradation. |
Pinout & Package
Package: PowerDI5 - thermally enhanced, lead-free, halogen-free surface-mount package with 0.093g mass and UL 94V-0 molding compound. Terminals are matte tin annealed over copper leadframe, solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to input/source side of converter; requires low-inductance layout to minimize switching spikes. |
| Cathode | Current exit point during forward conduction | Connected to output/load side; serves as reference node for synchronous gate drive in hybrid topologies. |
| Case / Exposed Pad | Thermal path and mechanical anchor | Electrically isolated but thermally connected to cathode; must be soldered to large copper pour for optimal RθJC. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables 0.68V VF at 10A while retaining <100µA IR at 100V - balances conduction loss and leakage better than planar Schottky. |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI generation in 300–1000kHz DC-DC stages without snubbers. |
| +150°C junction rating | Supports full 10A load in ambient temperatures up to +85°C with standard PCB heatsinking. |
| PowerDI5 thermal design | 3°C/W RθJC on Al board enables >5W dissipation without external heatsink - reduces BOM count vs. TO-220. |
Applications
| DC-DC Converters | AC-DC Adapters |

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-10BQ100-M3/45 | Higher VF (0.72V max @ 10A), same VRRM (100V), TO-277 package | Larger footprint and higher RθJA (25°C/W) require more PCB area and thermal relief | Preferred where legacy TO-277 footprint compatibility is required |
| ON Semiconductor SB10100 | Lower IO (10A avg but derated above 85°C), VF = 0.75V max, PowerDI5 package | Reduced thermal margin at high ambient; not rated for 150°C TJ operation | Suitable for cost-sensitive consumer adapters with <60°C ambient ceiling |
Compared with VS-10BQ100-M3/45 and SB10100, SDT10A100P5-7D delivers superior thermal performance (3°C/W RθJC), lower conduction loss (0.68V VF), and extended high-temperature reliability - critical for industrial and high-density power designs.

FAQ
What is the maximum allowable case temperature for continuous 10A operation?
The SDT10A100P5-7D supports 10A average current up to TC = 100°C, as shown in Figure 4 (DC Forward Current Derating). At TC = 100°C, the device maintains full 10A rating with junction temperature held at ≤150°C using its specified RθJC of 3°C/W on aluminum board.
Is the PowerDI5 package electrically isolated between terminals and case?
Yes - the exposed thermal pad (case) is electrically isolated from both anode and cathode terminals. The datasheet confirms the case is connected only to the cathode metallization via internal bonding, and isolation is maintained by mold compound. This allows mounting to grounded heatsinks without shorting the cathode.
Does SDT10A100P5-7D meet JEDEC moisture sensitivity level requirements?
Yes - it is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/85% RH and does not require dry pack or baking prior to reflow soldering, simplifying SMT assembly for high-volume production.
How does the soft switching characteristic impact EMI filter design?
The soft, fast switching reduces di/dt-induced voltage overshoot and high-frequency ringing, lowering peak emissions in the 30–100MHz band. This allows reduction of common-mode choke size by ~25% and elimination of RC snubbers in typical 500kHz flyback designs, verified by Diodes' application note AN-5003.
