Programmable Unijunction Transistor

Programmable Unijunction Transistor Triggers

Designed to enable the engineer to “program’’ unijunction characteristics such as RBB, η, IV, and IP by merely selecting two resistor values. Application includes thyristor−trigger, oscillator, pulse and timing circuits. These devices may also be used in special thyristor applications due to the availability of an anode gate. Supplied in an inexpensive TO−92 plastic package for high−volume requirements, this package is readily adaptable for use in automatic insertion equipment.

Features

• Programmable − RBB, η, IV and IP

• Low On−State Voltage − 1.5 V Maximum @ IF = 50 mA

• Low Gate to Anode Leakage Current − 10 nA Maximum

• High Peak Output Voltage − 11 V Typical

• Low Offset Voltage − 0.35 V Typical (RG = 10 kΩ)

• Pb−Free Packages are Available*

2N6028属于分立半导体产品 > 晶体管 - 可编程单结。安森美半导体公司制造生产的2N6028晶体管 - 可编程单结可编程单结晶体管 (PUT) 与可控硅整流器 (SCR) 器件非常相近，其特性行为类似于具有用户可配置阈值电压的单向 DIAC。该器件虽适用于构建低频振荡器和定时功能、SCR 触发应用等，但可满足此类需求的替代技术得到了更多用户青睐。
