MZT2970

The MZT2970 Series is a 10 Watt zener transient suppressors, it's designed to product voltage sensitive components from high voltage energy transients. MZT2970 have low zener impedance and fast response time. The highly reliable TO-220 package features low thermal resistance and high heat dissipation. This series is ideally suited for use in communication systems, numerical controls, process controls, medical equipment, business machines, power supplies and numerous other industrial/consumer applications.

Here are some feature of the the MZT2970 Series. The first one is: the Voltage Range of 6.8 to 200 Volts. The second one is: the Silicon Oxide Passivated junctions. The third one is: 600 Watts Peak Power Rating @1.0ms.  And the last one is: TO-220 Package.

The  MZT2970 Series has some important  parameters, whose symbol and absolute maximum ratings are as follows: one is the Steady State Power Dissipation PD, is 10 Watts @ Tc=120 and 333 mW/ Derate above Tc-120. The another parameter is Operating and Storage Junction Temperature Range, Tj,Tstg is -65 to +150.

Next are some application notes for you. Special Devices: matched sets and back-to-back configurations for bidirectional applications can be ordered upon special request, Contact your nearest Motorola representative. Response Time: in most applications, the transient suppressor device is placed in parallel with equipment or component to be protected. In this situation ,there is a time delay associated with the capacitance of the device and an overshoot condition associated with the inductance of the connection method. And some notes about the parameters of MZT2970. The maximum zener current ratings are based on maximum voltage of 20% tolerance unit.For closer tolerance units(10% or 5%) or units where the actual zener voltage (Vz) id known at the operating point, the maximum zener current may be increased and is limited by the derating curve.
