Mechanical shock	Mil-STD-883D, Method 2002.3, 1 msec, 1/2 sine, mounted		500	G
Mechanical vibration	Mil-STD-883D, Method 2007.2, 20-2000Hz		20	G

(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.

(2) The ambient temperature is the air temperature of the surrounding environment. The junction temperature is the temperature of the internal power IC when the device is powered. Operating below the maximum ambient temperature, as shown in the safe operating area (SOA) curves, ensures that the maximum junction temperature of any component inside the module is never exceeded.

6.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±2500	V
V_(ESD)	Electrostatic discharge	Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±1500	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.

T_J	Operating IC junction temperature ⁽¹⁾	–40	125	°C
T_A	Operating ambient temperature ⁽¹⁾	–40	85	°C

(1) The ambient temperature is the air temperature of the surrounding environment. The junction temperature is the temperature of the internal power IC when the device is powered. Operating below the maximum ambient temperature, as shown in the safe operating area (SOA) curves, ensures that the maximum junction temperature of any component inside the module is never exceeded.

6.4 Thermal Information

THERMAL METRIC⁽¹⁾		TPSM84A21	UNIT
		MOJ (QFM)
		20 PINS
R_θJA	Junction-to-ambient thermal resistance ⁽²⁾	14.9	°C/W
ψ_JT	Junction-to-top characterization parameter ⁽³⁾	2.2	°C/W
ψ_JB	Junction-to-board characterization parameter ⁽⁴⁾	5.7	°C/W

(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953.

(2) The junction-to-ambient thermal resistance, Θ_JA, applies to devices soldered directly to a 50 mm x 100 mm double-sided PCB with 2 oz. copper and natural convection cooling. Additional airflow reduces Θ_JA.

(3) The junction-to-top board characterization parameter, Θ_JT, estimates the junction temperature, T_J, of a device in a real system, using a procedure described in JESD51-2A (section 6 and 7). T_J = ψ_JT * Pdis + T_T; where Pdis is the power dissipated in the device and TT is the temperature of the top of the device.

(4) The junction-to-board characterization parameter, ψ_JB, estimates the junction temperature, T_J, of a device in a real system, using a procedure described in JESD51-2A (sections 6 and 7). T_J = ψ_JB * Pdis + T_B; where Pdis is the power dissipated in the device and T_B is the temperature of the board 1mm from the device.
