Product details
Overview
SDT8A100P5-13D from Diodes Incorporated is a 100 V, 8 A Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.7 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 serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT8A100P5-13D datasheet, SDT8A100P5-13D pinout, SDT8A100P5-13D application, or SDT8A100P5-13D equivalent, key selection criteria include low VF stability across temperature, soft fast switching for EMI control, thermal resistance (RθJC = 3°C/W on 2"×2" Al substrate), and RoHS-compliant green packaging with matte tin terminations.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage performance versus planar Schottky diodes. Its soft recovery minimizes voltage overshoot during turn-off in inductive switching circuits.
The PowerDI5 package enables low thermal resistance (RθJA = 18°C/W on aluminum substrate) and supports high-current operation without external heatsinking in space-constrained power stages. Junction-to-case thermal path is optimized via direct die attach to exposed copper leadframe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or buck output stage. |
| IO(AV) | 8 A - Continuous average forward current rating at TC = 115°C; supports compact 12–24 V DC-DC outputs. |
| VF(MAX) | 0.70 V @ IF = 8 A, TJ = 25°C - Low conduction loss improves efficiency in high-frequency synchronous rectification alternatives. |
| IR(MAX) | 0.1 mA @ VR = 100 V, TJ = 25°C - Tight leakage spec ensures stable biasing in high-impedance feedback networks. |
| TJ(max) | +150°C - Enables operation in thermally demanding environments like enclosed power adapters or automotive under-hood modules. |
| RθJC | 3°C/W - Confirmed on 2"×2" aluminum PCB; allows precise junction temperature estimation for thermal design margining. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed copper leadframe for low RθJC and high power density. Dimensions: 3.966 mm × 6.51 mm × 1.10 mm (L×W×H), weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point under forward bias | Connected to switch node (e.g., MOSFET drain) in buck/flyback secondary side; requires low-inductance layout. |
| Cathode (Pin 2) | Current exit point under forward bias | Connected to output rail; large copper pour required for heat spreading and low ESR return path. |
| Exposed Pad (Pin 3) | Thermal & electrical ground connection | Internally tied to cathode; must be soldered to ≥200 mm² copper area for optimal RθJA and mechanical reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~0.15 V vs. planar Schottky at 8 A, directly lowering conduction loss in 500 kHz–1 MHz converters. |
| Soft, fast switching | Reverse recovery time < 20 ns with minimal ringing; reduces EMI filter component count in Class B/C power supplies. |
| +150°C junction rating | Enables derated operation at 115°C case temperature without thermal runaway-critical for sealed adapter enclosures. |
| Green, halogen-free molding compound | UL 94V-0 rated, <900 ppm Br/Cl, <1000 ppm Sb; meets IPC-1752A reporting requirements for automotive Tier 1 BOMs. |
Applications
| DC-DC Buck Converter Output Rectifier | AC-DC Adapter Secondary Side |
|---|---|
Use Scenario: High-frequency (500 kHz–1 MHz) non-synchronous buck converter delivering 5–12 V/6–8 A to FPGA or ASIC core rails. IC Role / Device Role / Timing Role: Freewheel diode conducting during low-side switch off-time; defines minimum on-time and ripple amplitude. Use Value: 0.7 V VF at 8 A reduces conduction loss by >1.2 W vs. standard Schottky, enabling smaller heatsink or higher ambient rating. | Use Scenario: 24 W wall-mounted AC-DC adapter with universal input (90–264 VAC) and regulated 12 V/2 A output. IC Role / Device Role / Timing Role: Output rectifier in flyback secondary winding; handles peak currents up to 150 A surge during startup. Use Value: 0.1 mA IR at 100 V prevents output voltage drift during no-load standby, meeting DOE Level VI efficiency requirements. |
| Industrial Motor Drive Snubber | LED Driver Constant-Current Loop |
Use Scenario: IGBT snubber network in 24 V BLDC motor controller handling 10 A continuous phase current. IC Role / Device Role / Timing Role: Clamping diode absorbing inductive kickback energy during IGBT turn-off; operates in unidirectional pulse mode. Use Value: Soft recovery limits dv/dt-induced gate oscillation, reducing false triggering risk in high-noise motor environments. | Use Scenario: Constant-current LED driver for architectural lighting (36 V string, 700 mA) with PWM dimming at 1–10 kHz. IC Role / Device Role / Timing Role: Blocking diode isolating current sense resistor from reverse polarity transients during PWM edge transitions. Use Value: 3°C/W RθJC allows direct mounting to aluminum heat sink, maintaining ±1% current regulation over –40°C to +85°C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS810H-TP (Micro Commercial) | Same 100 V/8 A rating but VF = 0.85 V @ 8 A; RθJC = 4.5°C/W; no AEC-Q200 qualification path. | Limited to commercial-grade power supplies; not recommended for automotive or industrial temp-cycled environments. | Select only if cost sensitivity outweighs 0.15 V VF penalty and thermal margin is >15°C. |
| SB8100-E3/54 (Vishay) | DO-201AD package; VF = 0.82 V @ 8 A; RθJA = 40°C/W; leads require wave soldering or hand assembly. | Suitable for through-hole prototyping or legacy board rework; incompatible with fine-pitch SMT lines. | Choose only when PowerDI5 footprint is unavailable and manual assembly is acceptable. |
Compared with SS810H-TP and SB8100-E3/54, SDT8A100P5-13D delivers superior thermal performance (3°C/W vs. ≥4.5°C/W), lower conduction loss (0.7 V vs. ≥0.82 V), and automated SMT compatibility-making it optimal for high-density, high-reliability power modules.

FAQ
What is the maximum allowable case temperature for continuous 8 A operation?
The datasheet specifies IO = 8 A at TC = 115°C. Derating begins above this point per Figure 4: at TC = 125°C, max IF(AV) drops to ~7.2 A. Operation beyond TC = 135°C is not recommended without active cooling or reduced load.
Does SDT8A100P5-13D meet AEC-Q101 for automotive use?
No-this part is not AEC-Q101 qualified. Diodes offers AEC-Q101 variants (e.g., SDT8A100Q5) with PPAP documentation and IATF 16949 manufacturing. SDT8A100P5-13D is rated for industrial/commercial applications only.
How does the PowerDI5 package improve thermal performance over SMA or SMB?
PowerDI5's exposed cathode pad achieves RθJC = 3°C/W on aluminum substrate-nearly 3× better than SMA (RθJC ≈ 8.5°C/W). This enables 30–40% higher power density in same PCB area and eliminates need for thermal vias in many designs.
Can SDT8A100P5-13D replace a 100 V/10 A Schottky in an existing design?
Only with verification: its 8 A rating is 20% lower than 10 A parts. Check peak current margins, thermal rise under worst-case load, and transient surge capability (IFSM = 150 A). If design operates ≤8 A RMS with ≥15°C thermal headroom, replacement is viable.
