2N1597 Description

Short technical summary and product information.

The 2N1597 from NJS is a silicon thyristor, also known as a silicon controlled rectifier (SCR). This industrial-type, low-current device is housed in a TO-39 package, making it suitable for printed-circuit board applications.

Key electrical specifications include a maximum forward current of 1.6 amperes RMS and a peak surge current capability of 15 amperes for one cycle at 60Hz. The device can handle a peak reverse blocking voltage of up to 400V and a peak forward blocking voltage of 400V. Its operating junction temperature range is from -65°C to +125°C.

Additional electrical characteristics include a typical gate trigger current of 2mA and a typical gate trigger voltage of 0.7V. The forward on-voltage is typically 1.1V at 1A, with a maximum of 2V. Turn-on time is a rapid 0.8µs, and turn-off time is typically 10µs under specified conditions.

The TO-39 package has dimensions of 6.25mm (A) by 13.59mm (B), with a diameter of 9.24mm (C). The pinout includes Cathode (Pin 1), Gate (Pin 2), and Anode (Pin 3). This component is ideal for various industrial control applications requiring reliable switching.
