This high power Transient Voltage Suppressor and Zener is designed for applications requiring protection of voltage-sensitive electronic devices that may be damaged by high power or high energy voltage transientsincluding lightning per IEC61000-4- 5 and classes 1-4 with various source impedances described herein. Individual cells are matched to ensure current - sharing under high current pulse conditions and for continuous operation as a Zener when required.

FEATURES:

• Peak Surge power capacity give from 0.1 ms to 10 seconds.
• Low clamping Factor
• Negligible power loss
• Small size and weight for 350W DC rating
• Low Thermal Resistance junction to base plate
• Transient Peak Pulse Power: 40 kW at 0.1 ms (see Figure 1)
• DC Power Dissipation: 350 Watts @ TC = 25°C (Derate 2.33 W/°C above 25°C)
• Operating junction & storage temperature range: -65°C to +175°C
   

Electrical Characteristics (TA = 25°C, VF = 1.5 V max @ 10 A for all types):

• Rated Standoff Voltage (Note 1): 28 Vwm Vdc / 20 Vwm Vrms
• Maximum Device Clamping Factor CF=Vz@Iz (pulse) ÷ Vz@Izt (Note 2): 1.25
• Minimum Zener Voltage: 32 Vz (min) Vdc @ 0.2 Izr Adc
• Maximum Zener Voltage Pulse Width = 1.0 ms: 50 Vz (max) Vdc @ 100 Iz (pulse) Adc
• Maximum Standby Current Id @ Vwm µAdc: 50
• Typical Capacitance C (typ) @ Vwm µF: 0.011

Note 1: Rated Standoff Voltage (Vwm) is defined as normal input voltage to device for non-oerating condition.  If non-sinusoidal wave or dc input is present, the peak operating voltage input values for Vwm should be used to select device type.
