The 2N682 is a high-reliability silicon controlled rectifier (SCR) housed in a TO-48 / TO-208AA stud-mount metal package, engineered for dependable power control and switching in demanding industrial, aerospace, and defense environments. It is a member of the 2N68x–2N69x family of reverse-blocking SCRs (2N681–2N692), offering a range of voltage ratings to meet diverse power application needs.
The 2N682 provides a repetitive peak off-state voltage (V_DRM / V_RRM) of approximately 500 V, an RMS on-state current of 25 A, and a non-repetitive surge current up to 150 A. Devices are available as standard 2N682 or qualified to JAN / JANTX standards per MIL-PRF-19500/108, ensuring outstanding reliability and consistent performance under extreme conditions.
When a gate signal is applied, the SCR conducts current from anode to cathode and remains on until current drops below the holding current. This makes it ideal for controlled rectification, power regulation, and switching.
