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 (V_BR)

•

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):

t_clamping(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 4mm²copper pads (1oz)

and track width 1mm, length 25mm

Steady-State Power Dissipation:

Forward Surge:

5 watts at T_L=40°C or 1.52 watts @ T_A=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)
