Diodes Incorporated DSC06065FP

Overview

DSC06065FP from Diodes Incorporated is a 650 V, 6 A silicon carbide Schottky diode in ITO220AC (Type WX-NC) package, designed as a high-efficiency rectifier or freewheeling diode for power conversion stages. It delivers low forward voltage (1.7 V max at 6 A, 25°C), ultra-low reverse leakage (0.59 µA at 650 V, 25°C), and stable operation up to +175°C junction temperature-enabling use in industrial motor drives and UPS systems.

For engineers reviewing the DSC06065FP datasheet, DSC06065FP pinout, DSC06065FP application, or DSC06065FP equivalent, key selection criteria include its SiC-based zero-recovery switching, thermal resistance (R_θJC = 7 °C/W), surge capability (36 A IFSM), and compatibility with high-frequency PFC and inverter topologies requiring minimal conduction loss and high-temperature reliability.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-efficiency AC/DC and DC/DC converters. Its unipolar structure eliminates minority-carrier storage, enabling near-zero reverse recovery charge (QC = 15 nC) and eliminating switching tail current-critical for reducing EMI and MOSFET turn-off losses in totem-pole PFC and three-phase inverters.

The device operates with a positive temperature coefficient on VF, improving current sharing in parallel configurations. Its rated VRRM of 650 V supports 400 V AC input systems with margin, while R_θJL = 5 °C/W enables direct mounting to copper heatsinks without thermal interface material in many industrial designs.

FAQ

Is DSC06065FP pin-compatible with standard ITO220AC silicon diodes?

Yes-DSC06065FP uses the industry-standard ITO220AC (Type WX-NC) outline with identical mechanical dimensions and lead spacing. The cathode is connected to the isolated metal tab, matching conventional layout practices for heat sinking and isolation. No PCB redesign is needed for drop-in replacement.

What is the maximum allowable case temperature for continuous 6 A operation?

Per the forward current derating curve (Fig.1), DSC06065FP supports 6 A average current only up to TC = 25°C. At TC = 100°C, the rated IO drops to approximately 3.5 A. Thermal design must ensure case temperature stays within this limit using appropriate heatsinking and airflow.

Does DSC06065FP require a gate driver or control signal?

No-DSC06065FP is a passive two-terminal device with no control inputs. It conducts when anode voltage exceeds cathode voltage by >VF and blocks when reverse biased. Unlike MOSFETs or IGBTs, it requires no gate drive circuitry, simplifying implementation in rectifier and freewheeling roles.

Why is DSC06065FP marked "not recommended for new designs"?

Diodes Incorporated has superseded DSC06065FP with DSC06A065FP, which features improved VF, lower IR, and enhanced process consistency. While DSC06065FP remains fully functional and supported, new designs should adopt the newer variant to benefit from performance gains and long-term supply assurance.
