Absolute Maximum Ratings (TA = 25C unless otherwise noted) Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

*Typical values at TA = 25C Notes: 2. Test voltage must be applied within dv/dt rating. 3. All devices are guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating IF lies between max IFT (15mA for MOC3081M, 10mA for MOC3082M, 5mA for MOC3083M) and absolute max IF (60mA). 4. This is static dv/dt. See Figure 9 for test circuit. Commutating dv/dt is a function of the load-driving thyristor(s) only. 5. Isolation surge voltage, VISO, is an internal device dielectric breakdown rating. For this test, Pins 1 and 2 are common, and Pins 4, 5 and 6 are common.

800V Vdc
1. The mercury wetted relay provides a high speed repeated pulse to the D.U.T.
RTEST 10 k CTEST
2. 100x scope probes are used, to allow high speeds and voltages. 3. The worst-case condition for static dv/dt is established by triggering the D.U.T. with a normal LED input current, then removing the current. The variable RTEST allows the dv/dt to be gradually increased until the D.U.T. continues to trigger in response to the applied voltage pulse, even after the LED current has been removed. The dv/dt is then decreased until the D.U.T. stops triggering. RC is measured at this point and recorded.

Typical circuit for use when hot line switching is required. In this circuit the "hot" side of the line is switched and the load connected to the cold or neutral side. The load may be connected to either the neutral or hot line. Rin is calculated so that IF is equal to the rated IFT of the part, 15mA for the MOC3081M, 10mA for the MOC3082M, and 5mA for the MOC3083M. The 39 resistor and 0.01F capacitor are for snubbing of the triac and may or may not be necessary depending upon the particular triac and load use.

Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
