Parameter table

Absolute Maximum Ratings（1）

At 25°C free-air temperature (unless otherwise noted)

Symbol	Parameter	Min	Max	Unit
VCC	Collector to emitter voltage		50	V
VR	Clamp diode reverse voltage(2)		50	V
VI	Input voltage(2)		30	V
ICP	Peak collector current		500	mA
IOK	Output clamp current		500	mA
ITE	Total emitter-terminal current		–2.5	A
TA	Operating free-air temperature range	–20	70	°C
θJA	Thermal Resistance Junction-to-Ambient(3)		63	°C/W
θJC	Thermal Resistance Junction-to-Case(4)		12	°C/W
TJ	Operating virtual junction temperature		150	°C
TSTG	Storage temperature range	–40	85	°C

Exceeding the absolute maximum rating may cause permanent damage to the chip. These are only maximum ratings and prolonged use at absolute maximum ratings may affect the reliability of the chip.
All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
Maximum power dissipation is a function of TJ(max), θJC, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJC. Operating at the absolute maximum TJ of 150°C can affect reliability.
