3N187 Description

Short technical summary and product information.

The 3N187 is an N-channel JFET (Junction Field-Effect Transistor) from Harris Semiconductor. It is designed for general-purpose analog switching and amplification circuits. Key electrical specifications include a maximum drain-source voltage (Vds) of 20V and a typical drain current (Idss) of 5mA at Vds=15V. The device features a low input capacitance (Ciss) of 8.5pF maximum at 15V, making it suitable for high-frequency applications. The gate-source cutoff voltage (Vgs(off)) is 6.5V. Power dissipation is rated at 330mW, and the operating junction temperature range spans from -65°C to 175°C.

 

The 3N187 is housed in a through-hole TO-206AF / TO-72-4 Metal Can package, with the supplier device package designated as TO-72. This robust metal can package provides excellent thermal performance and reliability. The component is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited).

 

As a JFET, the 3N187 offers high input impedance and low noise, making it suitable for use in low-level signal processing, analog switches, and voltage-controlled resistors. Its wide operating temperature range allows use in harsh environments.
