It is the industry wide RAD tolerant replacement for the LH0002. The device is ideal for use with an operational amplifier in a closed loop configuration to increase current output. The MSK 0002RH is designed with a symmetrical output stage that provides low output impedances to both the positive and negative portions of output pulses. The MSK 0002RH is packaged in a hermetic 8 lead low profile T0-5 header and is specified over the full military temperature range.

RΘSA = ((TJ - TA)/PD) - (RΘJC) - (RΘCS) = ((125°C - 80°C) / 0.36W) - 55°C/W - 0.15°C/W = 125 - 55.15 = 69.9°C/W This heat sink in this example must have a thermal resistance of no more than 69.9°C/W to maintain a junction temperature of no more than +125°C. Thermal Model: Typical Applications: Governing Equation: TJ=PD X (RΘJC +RΘCS +RΘSA) +TA Where TJ=Junction Temperature PD=Total Power Dissipation RΘJC=Junction to Case Thermal Resistance RΘCS=Heat Sink to Ambient Thermal Resistance TC=Case Temperature TA=Ambient Temperature TS=Sink Temperature Example: This example demonstrates a worst case analysis for the buffer output stage. This occurs when the output voltage is 1/2 the power supply voltage. Under this condition, maximum power transfer occurs and the output is under maximum stress. Conditions: VCC= ±12VDC Vo= ±6Vp Sine Wave, Freq. = 1KHz RL= 100Ω For a worst case analysis we will treat the ±6Vp sine wave as an 6 VDC output voltage. 1.) Find Driver Power Dissipation PD= (Vcc-Vo) (Vo/RL) = (12V-6V) (6V/100Ω) = 360mW 2.) For conservative design, set TJ=+125°C Max. 3.) For this example, worst case TA=+80°C 4.) RΘJC = 55° C/W from MSK 0002RH Data Sheet 5.) RΘCS = 0.15° C/W for most thermal greases 6.) Rearrange governing equation to solve for RΘSA 3 Rev. A 4/07 TYPICAL PERFORMANCE CURVES 4 Rev.
