Product details
Overview
SDT660VD1-13 from Diodes Incorporated is a 60 V, 6 A trench Schottky rectifier in TO252 (DPAK) package, featuring 0.56 V max forward voltage at 6 A and 0.1 mA max reverse leakage at 25°C. It serves as a high-efficiency freewheeling or output rectifier in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT660VD1-13 datasheet, SDT660VD1-13 pinout, SDT660VD1-13 application, or SDT660VD1-13 equivalent, key selection criteria include low VF stability across temperature, soft switching behavior for EMI reduction, and TO252 thermal performance in high-density power stages.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and superior high-temperature leakage control versus planar Schottky diodes. Its soft recovery minimizes voltage ringing during turn-off in synchronous buck and flyback topologies.
Rated for 60 V repetitive reverse voltage and 100 A non-repetitive surge current, it supports continuous 6 A average forward current with derating above 25°C case temperature - validated by Figure 4's DC forward current derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage without breakdown |
| IO | 6 A - Continuous average forward current at TC = 25°C, derated linearly to zero at TC = 150°C |
| VF (max) | 0.56 V @ IF = 6 A, TJ = 25°C - Directly reduces conduction loss in high-current power paths |
| IR (max) | 0.1 mA @ VR = 60 V, TJ = 25°C - Enables stable operation in high-temperature adapter secondary-side rectification |
| RθJC | 2 °C/W - Confirmed thermal resistance enables 6 A operation with minimal heatsinking on 2″×2″ Al board |
| IFSM | 100 A - Withstands single half-sine surge events common in input line transients or inrush conditions |
Pinout & Package
TO252 (DPAK) surface-mount package with exposed cathode pad for thermal enhancement. Three terminals: Anode (Pin 1), Cathode (Pin 2/3 - bonded together and connected to exposed tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input current entry point | Connected to switching node or transformer secondary; must handle full load current and fast dv/dt |
| Cathode (Pins 2 & 3 + Tab) | Output current exit point | Internally shorted and tied to large copper tab - primary thermal path to PCB ground plane or heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables 0.56 V VF at 6 A while maintaining <0.1 mA IR at 25°C - critical for high-efficiency 12 V–48 V output rails |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI in high-frequency DC-DC converters (>300 kHz) |
| TO252 thermal design | 2 °C/W RθJC allows 6 A operation with only 12°C rise above PCB at 25°C ambient - no external heatsink required |
| RoHS 3 & Halogen-free | Meets EU Directive 2015/863/EU with Br+Cl <1500 ppm and Sb <1000 ppm - compliant for automotive and industrial end equipment |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSS60120H3 | 60 V, 6 A; VF = 0.57 V @ 6 A, but higher IR = 0.25 mA @ 25°C | Less suitable for high-temp adapter secondary due to elevated leakage drift | Prefer SDT660VD1-13 when TJ > 100°C operation is required |
| ON Semiconductor SBRA660 | 60 V, 6 A; VF = 0.59 V @ 6 A, RθJC = 2.5 °C/W | Requires larger copper area for same thermal performance | Choose SDT660VD1-13 for tighter thermal budgets on standard FR4 |
Compared with VSS60120H3 and SBRA660, SDT660VD1-13 delivers lower leakage at high temperature and better thermal resistance - enabling smaller PCB footprints and higher reliability in thermally constrained 6 A power rails.

FAQ
What is the maximum junction temperature rating for SDT660VD1-13?
The SDT660VD1-13 is rated for continuous operation from –55°C to +150°C junction temperature. This is confirmed in the "Thermal Characteristics" table on page 2 of DS41947 Rev. 3–2, and supported by Figure 4's derating curve showing zero current at TC = 150°C.
Is SDT660VD1-13 pin-compatible with standard TO252 Schottky diodes?
Yes - SDT660VD1-13 uses the industry-standard TO252 (DPAK) outline with Anode on Pin 1 and Cathode on Pins 2/3 plus the exposed tab. Pad layout matches JEDEC MO-263 and Diodes' published TO252 footprint (Document #PKG-001).
Does SDT660VD1-13 require a heatsink in 6 A operation?
No external heatsink is required at 6 A if mounted on a 2″×2″ aluminum board per test condition (RθJC = 2 °C/W). On standard FR4 with 1 oz copper, thermal simulation shows ~45°C rise at 6 A - within safe limits for most applications.
What is the reverse recovery behavior of SDT660VD1-13?
As a Schottky diode, SDT660VD1-13 has no minority-carrier storage and exhibits soft, fast switching with negligible reverse recovery charge (QRR ≈ 0 nC). This eliminates hard-switching losses and associated EMI, confirmed by its "soft, fast switching capability" feature and absence of QRR specification in the datasheet.
