STTA1206D

STTA1206D Description

The STTA1206D from STMicroelectronics is a high-performance 600V, 12A general-purpose diode belonging to the TURBOSWITCH™ series. Designed for fast recovery applications (≤500ns), it features an ultra-low reverse recovery time (trr) of 55ns, making it ideal for high-efficiency power conversion. Encased in a TO-220AC through-hole package, this diode is RoHS3 compliant and operates reliably up to 150°C junction temperature. Its low forward voltage drop (1.75V @ 12A) and minimal reverse leakage current (100µA @ 600V) ensure reduced power losses and improved thermal management.

STTA1206D Features

• Fast Recovery: Optimized for ≤500ns recovery, suitable for high-frequency switching.
• High Voltage/Current Rating: 600V DC reverse voltage and 12A average rectified current.
• Low Power Dissipation: 1.75V max forward voltage enhances efficiency.
• Robust Construction: TO-220AC package ensures mechanical durability and heat dissipation.
• Compliance: RoHS3, REACH Unaffected, EAR99, and MSL1 (Unlimited) for broad industrial use.
• Low Leakage: 100µA @ 600V minimizes standby losses.
