  • tp = 16.7 ms, F = 60 Hz:The Triac can tolerate a maximum surge current of 168 A if the frequency is increased to 60 Hz with a somewhat shorter pulse width of 16.7 ms.

I2t Value for Fusing (dl/dt)

  • tp = 10 ms: The I2t value is 144 A2s, which is the amount of energy necessary to blow a fuse in 10 ms. This setting is critical in applications where fuses must be protected from excessive current.

Critical Rate of Rise of On-State Current (dl/dt)

  • Tj = 125 °C, IG = 2 x IGT, tr = 100 ns, F = 120 Hz: Under these conditions, the critical rate of rise of on-state current, dl/dt, is 50 A/s. When the gate current is double the gate trigger current (IGT), this value specifies how quickly the on-state current can climb.

Non-Repetitive Surge Peak Off-State Voltage (VDSM/VRSM)

  • Tj = 25 °C, tp = 10 ms: The Triac can tolerate a maximum non-repetitive surge peak off-state voltage of +100 V for a 10 ms pulse at 25 °C.

Peak Gate Current (IGM)

  • tp = 20 s, Tj = 125 °C: The maximum gate current that the T1635-600G-TR can take for a 20 s pulse at 125 °C is 4 A.

Average Gate Power Dissipation (PG(AV))

  • Tj = 125 °C: At a junction temperature of 125 °C, the average gate power dissipation is limited to 1 W. This value specifies the maximum power that can be safely applied to the Triac’s gate.

Storage and Operating Temperature Ranges

  • Temperature Range for Storage Junction: The Triac can be securely stored at temperatures ranging from -40 to +150 °C.
  • Operating Junction Temperature Range: The Triac should be utilized within an operating junction temperature range of -40 to +125 °C for normal operation.
