GT(Tj)/ IGT(25˚C), versus junction temperature Tj.

Fig.8. Normalised latching current I

L(Tj)/ IL(25˚C),

versus junction temperature T

j.

Fig.9. Normalised holding current I

H(Tj)/ IH(25˚C),

versus junction temperature T

Fig.10. Typical and maximum on-state characteristic.

Fig.11. Transient thermal impedance Z

th j-mb, versus

pulse width t

p.

Fig.12. Typical commutation dV/dt versus junction

temperature, parameter commutation dI

T/dt. The triac

should commutate when the dV/dt is below the value

on the appropriate curve for pre-commutation dI

T/dt.
