6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
IR Reverse current 30 mA
IF Forward current 10 mA
TJ Operating virtual junction temperature 150 °C
Tstg Storage temeprature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000
(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.

6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
IZZ Reference current 0.01 20 mA
TA Operating free-air temperature 0 70 °C

αVZ Average temperature coefficient of reference voltage(3) IZ = I(min) to 20 mA(2) Full range ±20 ppm/°C
ΔVZ Change in reference voltage with current IZ = I(min) to 1 mA(2) 25°C 1 mV
Full range 1.5
IZ = I(min) to 20 mA 25°C 20
Full range 30
ΔVZ/Δt Long-term change in reference voltage IZ = 100 µA 25°C ±20 ppm/khr
IZ(min) Minimum reference current Full range 8 15 µA
ZZ Reference impedance IZ = 100 µA, f = 25 Hz 25°C 0.4 1 Ω
Full range 1.5
Vn Broadband noise voltage IZ = 100 µA, f = 10 Hz to 10 kHz 25°C 60 µV
(1) Full range is −40°C to 85°C for the LM385-1.2-MIL.
(2) I(min) = 15 μA for the LM385-1.2-MIL.
(3) The average temperature coefficient of reference voltage is defined as the total change in reference voltage divided by the specified temperature range.
