These SCRs have a low gate current trigger level of 6mA or 15mA maximum at approximately 1.5V, with a sensitive version of this series having a gate trigger current less than 200µA. The sensitive gate SCR version is easily triggered by sense coils, proximity switches, and microprocessors. ## **Features & Benefits** [Po - Voltage capability up • 150°C maximum junction to 600 V temperature **==> picture [245 x 204] intentionally omitted <==** **----- Start of picture text -----**

Good design practice should limit the maximum continuous current through the main terminals to 75% of the component rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors. Correct mounting, soldering, and forming of the leads also help protect against component damage. ## **Part Numbering System** **==> picture [244 x 119] intentionally omitted <==** **----- Start of picture text -----**
