The 2N692 is a high-reliability silicon controlled rectifier (SCR) built for precision power control and switching in the most demanding aerospace, defense, and industrial systems. It comes in a rugged TO-48 / TO-208AA stud-mount metal package, ensuring outstanding thermal performance, mechanical integrity, and long-term operational reliability. As a key member of the 2N68x–2N69x family of reverse-blocking SCRs (2N681–2N692), it delivers reliable operation across a range of high-voltage and high-power applications.
The 2N692 provides a repetitive peak off-state voltage (V_DRM / V_RRM) of approximately 1200 V, an RMS on-state current of 25 A, and a non-repetitive surge current rating up to 150 A. It is available as standard, JAN, or JANTX-qualified per MIL-PRF-19500/108, guaranteeing consistent, mission-critical reliability for harsh environments and extended service life.
A positive gate trigger signal switches the SCR from a non-conductive to a conductive state between the anode and cathode. It remains latched on until the current falls below its holding threshold, making it ideal for controlled power regulation and rectification.
