Description

The T1R is a series of fast silicon thyristors of 1 A listed in the Agenda radioelectronistului (2nd edition, 1989) among the thyristors made in Romania by IPRS Băneasa, in six voltage classes from 50 V (T1R-05) to 800 V (T1R-8) in a TO-126 / TO-39 (SOT-32) package [1]. The values of each code are in the Variants table.

Coded as (IPRS Băneasa code for thyristors) [2]:

Part Meaning
T thyristor
1 on-state current IT = 1 A
R fast (short turn-off time tq)
05…8 repetitive peak reverse voltage VRRM in hundreds of volts (05 = 50 V … 8 = 800 V)

IT(AV)M at Tc = 100 °C; ITRM at Tc = 100 °C; ITSM for 10 ms; VRRM (= VDRM) at Tc = 125 °C; dV/dt at Tc = 125 °C [1].
