Product details
Overview
SDT5A100P5-7D 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 junction temperature rating. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT5A100P5-7D datasheet, SDT5A100P5-7D pinout, SDT5A100P5-7D application, or SDT5A100P5-7D equivalent, key selection criteria include low VF stability across -55°C to +150°C, thermal resistance of 3°C/W junction-to-case (with heatsink), soft switching behavior, and RoHS-compliant green packaging for space-constrained power stages.
Technical Context
This Schottky rectifier uses trench MOS-based anode structure to achieve lower forward voltage and reduced reverse recovery charge versus planar Schottky diodes. Its 0.63V typical VF at 5A/125°C enables higher efficiency in thermally stressed 12V–48V output rails.
The device exhibits soft reverse recovery with no minority-carrier tail, eliminating snubber requirements in synchronous buck secondary-side rectification. Junction capacitance is 1000pF at 4V reverse bias, supporting stable high-frequency operation up to 1MHz without excessive capacitive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage before avalanche; supports 48V bus designs with 2× safety margin |
| IO (AV) | 5 A - Continuous DC current rating at 25°C ambient with recommended PCB layout |
| VF (max) | 0.66 V @ 5A, 25°C - Enables <3.3W conduction loss per device in 5A output stage |
| IR (max) | 50 µA @ 100V, 25°C - Low leakage preserves efficiency in standby and light-load modes |
| TJ (max) | +150°C - Allows operation in sealed enclosures or high-ambient industrial environments |
| RθJC | 3 °C/W - With external heatsink, supports >4W dissipation without exceeding TJ limit |
| Package | PowerDI5 - Surface-mount, thermally enhanced 3-pin outline with 0.093g mass and UL 94V-0 rating |
Pinout & Package
PowerDI5 is a 3-terminal surface-mount package with anode (pin 1), cathode (pin 2), and exposed thermal pad (pin 3) tied to cathode internally. The thermal pad must be soldered to a ≥50mm² copper area for rated current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to switching node or transformer secondary |
| Pin 2 | Cathode | Output terminal; ties directly to output capacitor and thermal pad |
| Pin 3 (Pad) | Cathode Thermal Plane | Internally connected to cathode; requires full-solder coverage to PCB for RθJC = 3°C/W |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~12% vs. planar Schottky at 5A, lowering conduction loss in 12V–48V outputs |
| Soft, fast switching | No reverse recovery tail current; eliminates need for RC snubbers in buck converter freewheel paths |
| +150°C operating junction | Enables use in sealed power supplies where case temperatures exceed 100°C |
| Halogen & antimony free | Meets IEC 61249-2-21 "Green" standard (<900ppm Br/Cl, <1000ppm Sb) |
| Matte tin terminals | Solderable per MIL-STD-202 Method 208; compatible with lead-free reflow profiles (peak 260°C) |

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-50SQ030NTR-M3 | 30V VRRM, 5A IO, 0.42V VF @ 5A - lower voltage rating, lower VF | Only suitable for ≤30V output rails; not interchangeable in 48V systems | Select only when VRRM margin <2× system voltage and ultra-low VF is critical |
| ON Semiconductor SB5100 | 100V VRRM, 5A IO, 0.85V VF @ 5A - higher VF, TO-220 package | Larger footprint, higher thermal resistance (RθJC ≈ 5°C/W), requires heatsink clip | Choose when legacy through-hole assembly or mechanical robustness outweighs size/efficiency needs |
Compared with VS-50SQ030NTR-M3 and SB5100, SDT5A100P5-7D uniquely balances 100V blocking, sub-0.66V VF, PowerDI5 thermal performance, and green compliance-making it optimal for modern surface-mount 48V-output power supplies where board space and thermal density are constrained.

FAQ
What is the maximum continuous forward current for SDT5A100P5-7D at 100°C case temperature?
At TC = 100°C, the device supports 2.5A average forward current per Figure 5 (DC Forward Current Derating). This is derived from the linear derating curve starting at 5A at TC = 25°C and reaching 0A at TC = 150°C, with slope −0.05A/°C.
Does SDT5A100P5-7D require a heatsink for 5A operation?
Yes - sustained 5A operation requires the thermal pad (Pin 3) to be soldered to a ≥50mm² copper area on a 2oz FR-4 PCB with an attached 50mm × 50mm × 23mm aluminum heatsink, achieving RθJA = 18°C/W per Note 7. Without heatsink, derating to ~2.2A is required at 25°C ambient.
Is SDT5A100P5-7D suitable for automotive under-hood applications?
No - while rated for −55°C to +150°C junction temperature, it is not AEC-Q101 qualified. Diodes Incorporated does not specify automotive-grade qualification, stress testing, or PPAP documentation for this part; use only in industrial or commercial environments.
How does the PowerDI5 package compare thermally to SMA or SMB packages?
PowerDI5 delivers RθJC = 3°C/W with heatsink - over 2× better than SMA (RθJC ≈ 7°C/W) and 3× better than SMB (RθJC ≈ 9°C/W). Its exposed cathode pad enables direct thermal path to PCB, whereas SMA/SMB rely on leadframe conduction only.
