SW-1634DA-CJ on stock Figure Al shows the classical protection circuit using the LCP152 crowbar concept. This topology has been developed to protect the new high voltage SLIC's. It allows to program the negative firing threshold while the positive clamping value is fixed at GND. When a negative su rge occurs on one wire (L1 for example) a current IG flows through the base of the tran- sistor Tl and then injects a current in the gate of the thyristor Thl. Thl fires and all the surge current flows through the ground. After the surge when the current flowing through Thl becomes less negative than the holding current IH, then Thl switches off. When a positive surge occurs on one wire (L1 for example) the diode Dl conducts and the surge current flows through the ground. 1. Index area: A notch or a pin one identification mark shall be locat- ed adjacent to pin one and shall be located within the shaded area shown. The manufacturer's identification shall not be used as a pin one identification mark. 2. The maximum limits of lead dimensions b and c or M shall be measured at the centroid of the finished lead surfaces, when solder dip or tin plate lead finish is applied. 3. Dimensions bl and cl apply to lead base metal only. Dimension M applies to lead plating and finish thickness. 4. Corner leads (1, N, N/2, and N/2+1) may be configured with a partial lead paddle. For this configuration dimension b3 replaces dimension b2. |
