The Central Semiconductor 2N4871 is a silicon PN unijunction transistor (UJT) designed for use in oscillator, triggering, and timing circuits. It features an intrinsic standoff ratio of 0.70 to 0.85 and an interbase resistance of 4.0 kΩ to 9.1 kΩ. The device can handle a maximum RMS emitter current of 1.5 A and a peak emitter current of 1.0 A (duty cycle ≤1%, PRR=10pps). Power dissipation is rated at 300 mW. The operating junction temperature range is -65°C to 125°C, with storage from -65°C to 150°C. The 2N4871 is housed in a TO-92 through-hole package, making it suitable for breadboarding and prototyping. Typical applications include relaxation oscillators, pulse generators, and timing circuits.
