1N6267-1N6303A  
1500W TRANSIENT VOLTAGE SUPPRESSOR  
High-reliability discrete products  
and engineering services since 1977  
FEATURES:  
Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number  
Available Non-RoHS (standard) or RoHS compliant (add PBF suffix)  
Available in both Unidirectional and Bidirectional (add C or CA suffix for bidirectional)  
Voltages from 6.8 to 180 V Breakdown (VBR)  
Suppresses transients up to 1500 watts @ 10/1000 μs (see Figure 1)  
Power rating = 1500 watts  
MAXIMUM RATINGS  
Peak Pulse Power Dissipation at 25°C:  
1500 watts @ 10/1000μs (see Figures 1, 2, & 3)  
Impulse Repetition Rate (duty factor):  
tclamping (0 volts to V(BR) min:  
0.01%  
<100 ps theoretical for unidirectional and <5 ns for bidirectional  
-65°C to +150°C  
Operating and Storage Temperature:  
Thermal Resistance:  
22°C/W junction to lead at 3/8”(10mm) from body, or 82°C/W junction to  
ambient when mounted on FR4 PC board with 4mm2 copper pads (1oz)  
and track width 1mm, length 25mm  
Steady-State Power Dissipation:  
Forward Surge:  
5 watts at TL=40°C or 1.52 watts @ TA=25°C when mounted on FR4 PC  
board described for thermal resistance  
200 Amps peak impulse of 8.3ms half-sine wave at 25°C (unidirectional  
only)  
Solder Temperature:  
260°C for 10 s (maximum)
