1N5555P-1N5558P
1500 WATT
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 as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix.
MAXIMUM RATINGS
1500 Watts for 10/1000µs with repetition rate of 0.01% or less* at lead temperature (TL) 25°C
Operating and Storage Temperatures
-65 to +175°C
Thermal Resistance
50°C/W junction to lead at 0.375” from body or 110°C/W junction to ambient when mounted
on FR4 PC board with 4 mm2 copper pads and track width 1mm, length 25mm
DC Power Dissipation *
1 Watt @ TL = 25°C 3/8 from body
Forward Surge Current
200 Amps for 8.3 ms half-sine wave @ TA = 25°C
Solder Temperatures
260°C for 10 s (maximum)
* TVS devices are not typically used for dc power dissipation and are instead operated at or less than their rated standoff voltage (VWM) except
for transients that briefly drive the device into avalanche breakdown (VBR to VC region).

Type
(note 1)
Note 1: A TVS is normally selected according to the rated “Standoff Voltage” VWM that should be equal to or greater than the dc or continuous
peak operating voltage level.
SYMBOLS AND DEFINITIONS
VWM
Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition
V(BR)
Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25°C
VC
Maximum Clamping Voltage: The maximum peak voltage appearing across the TVS when subjected to the peak pulse current in
a one millisecond time interval. The peak pulse voltage is the combination of voltage rise due to both the series resistance and
thermal rise and positive temperature coefficient (αV(BR))
IPP
Peak Pulse Current: The peak current during the impulse
PPP
Peak Pulse Power: The pulse power as determined by the product of VC and IPP
ID
Standby Current: The current at the standoff voltage (VWM)
I(BR)
Breakdown Current: The current used for measuring breakdown voltage (V(BR))
