Product details
Overview
SDT5A100P5 from Diodes Incorporated is a 5A, 100V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.66V max forward voltage at 5A/25°C, 50µA max reverse leakage at 100V/25°C, and 150°C maximum junction temperature. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT5A100P5 datasheet, SDT5A100P5 pinout, SDT5A100P5 application, or SDT5A100P5 equivalent, key selection criteria include low VF stability across temperature, thermal resistance (RθJC = 3°C/W with heatsink), soft switching behavior, and RoHS-compliant green packaging for space-constrained power stages.
Technical Context
This Schottky diode employs trench MOS structure to reduce forward voltage while maintaining tight IR control up to +150°C junction temperature. Its soft recovery minimizes EMI in high-frequency switching topologies like synchronous buck converters.
Thermal performance is defined by two RθJA values: 88°C/W on standard FR-4 (2oz Cu) and 18°C/W with a 50mm × 50mm × 23mm aluminum heatsink - enabling scalable thermal design for both board-level and heatsink-mounted deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 12–48V output DC-DC stages |
| IO(AV) | 5 A - Continuous average forward current rating at TA = 25°C; derates to ~3.5A at TC = 100°C per Figure 5 |
| VF Max | 0.66 V @ 5A, 25°C - Low conduction loss enables >95% efficiency in 5–12V output rails |
| IR Max | 50 µA @ 100V, 25°C - Tight leakage ensures minimal standby power loss in always-on adapter designs |
| TJ Max | +150°C - Enables operation in sealed enclosures or high-ambient industrial environments without forced cooling |
| RθJC | 3 °C/W - Confirmed with 2″×2″ Al substrate + heatsink; supports <10W dissipation with <30°C rise above case |
| Package | PowerDI5 - Surface-mount, thermally enhanced plastic package with exposed cathode pad for PCB heat spreading |
Pinout & Package
PowerDI5 is a 3-terminal surface-mount package with an exposed cathode pad (terminal 2) for thermal conduction. The anode (terminal 1) and cathode (terminal 2) are electrically isolated via molded compound; terminal 3 is the cathode tab connected internally to terminal 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Soldered to input/high-side node; carries full load current into device |
| 2 (Cathode) | Cathode connection | Main cathode terminal; electrically tied to exposed metal pad (terminal 3) for thermal path |
| 3 (Cathode Pad) | Thermal & electrical cathode | Exposed copper pad on bottom surface; must be soldered to large copper area for RθJC = 3°C/W performance |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~15% vs. planar Schottky at 5A, improving converter efficiency without increasing die size |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0); eliminates switching spikes and reduces snubber requirements in 300–1000kHz designs |
| +150°C junction rating | Enables use in sealed power supplies where ambient exceeds +85°C without derating or airflow |
| Halogen & antimony free | Meets IEC 61249-2-21 "Green" standard (<900ppm Br/Cl, <1000ppm Sb); supports eco-label compliance programs |
| Matte tin terminals | Lead-free, RoHS-compliant finish with MIL-STD-202 solderability; compatible with leaded and lead-free reflow profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSS5100-M3/5AT | Same 100V/5A rating; VF = 0.69V @ 5A/25°C; RθJC = 4.5°C/W; no halogen-free certification stated | Higher VF increases conduction loss by ~0.15W; slightly lower thermal performance limits peak power density | Preferred where cost sensitivity outweighs 3% efficiency gain and green compliance requirements |
| ON Semiconductor SB5100 | 100V/5A; VF = 0.72V @ 5A/25°C; RθJC = 5.0°C/W; lead-free but not halogen-free per datasheet | Higher VF and thermal resistance reduce usable current by ~0.8A at 100°C case temp | Acceptable for non-green-certified consumer adapters with relaxed thermal margins |
Compared with VSS5100-M3/5AT and SB5100, SDT5A100P5 delivers the lowest VF and best thermal resistance among 100V/5A Schottkys, with verified halogen-free compliance - making it optimal for high-density, thermally constrained, and eco-regulated power designs.

FAQ
What is the maximum allowable case temperature for continuous 5A operation?
The SDT5A100P5 supports 5A average forward current up to TC = 100°C, as shown in Figure 5. Beyond that, current must be linearly derated: at TC = 125°C, IO drops to ~2.5A. Operation above TC = 125°C requires active cooling or reduced load to maintain TJ ≤ 150°C.
Is the PowerDI5 package compatible with standard reflow soldering profiles?
Yes - the SDT5A100P5 uses matte tin terminals qualified to MIL-STD-202, Method 208, and supports both leaded and lead-free reflow. Peak temperature must not exceed 260°C for ≤10 seconds; preheat ramp rate ≤3°C/s; and time above 217°C ≤60 seconds per J-STD-020.
Does this diode have a specified reverse recovery time (trr)?
No - as a Schottky barrier device, the SDT5A100P5 has no minority-carrier storage, so trr is not applicable. Its switching is governed by junction capacitance (CT ≈ 400pF at 4V) and circuit inductance, resulting in soft, low-noise turn-off without reverse recovery spikes.
Can SDT5A100P5 replace a 100V/5A silicon PN rectifier in an existing design?
Yes - it offers direct drop-in replacement with significant benefits: ~0.4V lower VF reduces conduction loss by >2W at 5A, eliminates reverse recovery losses, and lowers EMI. Ensure layout provides adequate cathode pad copper area to realize RθJC = 3°C/W thermal performance.
