Its 45 ns reverse recovery time places it well inside the Fast Recovery =< 500ns class, making it suitable for switching power supply output rectification, flyback snubber clamps, and PFC boost stages where reverse-recovery charge drives switching loss. The 1.7 V forward drop at 1 A is the on-state voltage the thermal budget accounts for; at lower currents the drop scales down, but the 1.7 V figure is the worst-case for junction temperature calculation. ## Obsolete — no official successor listed STMicroelectronics lists the STTH106 as Obsolete on its product status. No direct replacement order code is provided in the lifecycle record. The base product number STTH10 covers the family, but the specific 600 V / 1 A variant in DO-41 has been phased out. For new designs, a functional alternative from the same STTH10x family with matching voltage and current ratings in a similar package should be evaluated. ## 1 µA leakage at 600 V — blocking performance Reverse leakage is specified at 1 µA maximum with 600 V applied across the junction. This low leakage is typical for fast-recovery epitaxial diodes in this voltage class and keeps standing power loss negligible in off-state periods. The junction temperature rating of 175°C maximum sets the thermal limit for the die; the axial lead and body must be derated per the thermal resistance of the mounting, but the 175°C Tj ceiling is the hard stop for the silicon.","metaTitle":"STTH106 Fast Recovery Rectifier, 600V 1A DO-41, 45ns trr","metaDescription":"ST STTH106 fast recovery rectifier: 600V Vrrm, 1A Io, 45ns trr, DO-41 axial package.
