7.1 Absolute Maximum Ratings⁽¹⁾

over operating free-air temperature range (unless otherwise noted)

	MIN	MAX	UNIT
Cathode voltage⁽²⁾, V_KA		37	V
Continuous cathode current, I_KA	–100	150	mA
Reference input current, I_I(ref)	–0.00005	10	mA
Operating virtual junction temperature⁽³⁾, T_J		150	°C
Lead temperature 1.6 mm (1/16 inch) from case for 10 s		260	°C
Storage temperature, T_stg	–65	150	°C

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) All voltage values are with respect to ANODE, unless otherwise noted.

(3) Long-term high-temperature storage and/or use at the absolute maximum ratings may result in a reduction of overall device life. See www.ti.com/ep_quality for additional information on enhanced plastic packaging.

7.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins⁽¹⁾	±4000	V
V_(ESD)	Electrostatic discharge	Charged device model (CDM), per JEDEC specification JESD22-C101, all pins⁽²⁾	±2000	V

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions

is defined as:

is positive or negative, depending on whether minimum V_I(ref) or maximum V_I(ref), respectively, occurs at the lower temperature.

(3) The output impedance is defined as:

When the device is operating with two external resistors (see Figure 9), the total dynamic impedance of the circuit is given by:
