DESCRIPTION
This Transient Voltage Suppressor (TVS) series for 1N5555 thru 1N5558 are JEDEC
registered selections for unidirectional devices. All have the same high Peak Pulse
Power rating of 1500 W with extremely fast response times. They are also available in
military qualified selections as described in the Features section herein. They are most
often used for protecting against transients from inductive switching environments,
induced RF effects, or induced secondary lightning effects as found in lower surge levels
of IEC61000-4-5. They are also very successful in protecting airborne avionics and
electrical systems. Since their response time is virtually instantaneous, they can also
protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

¾ Inherently radiation hard as described in Microsemi MicroNote 050
MAXIMUM RATINGS
¾ 1500 Watts for 10/1000 μs with repetition rate of 0.01% or less* at lead temperature (TL) 25oC (see Figs 1, 2, & 4)
¾ Operating & Storage Temperatures: -65o to +175oC
¾ THERMAL RESISTANCE: 50oC/W junction to lead at 0.375 inches (10 mm) from body or 110oC/W junction to
ambient when mounted on FR4 PC board with 4 mm2 copper pads (1oz) and track width 1 mm, length 25 mm
¾ DC Power Dissipation*: 1 Watt at TL = +25oC 3/8” (10 mm) from body (see derating in Fig 3)
¾ Forward surge current: 200 Amps for 8.3ms half-sine wave at TA = +25oC
¾ Solder Temperatures: 260 o C for 10 s (maximum)
MECHANICAL AND PACKAGING
¾ CASE: DO-13 (DO-202AA), welded, hermetically sealed metal and glass
¾ FINISH: All external metal surfaces are Tin-Lead plated and solderable per MIL-STD-750 method 2026
¾ POLARITY: Cathode connected to case and polarity indicated by diode symbol
¾ MARKING: Part number and polarity diode symbol
¾ WEIGHT: 1.4 grams. (Approx)
¾ TAPE & REEL option: Standard per EIA-296 (add “TR” suffix to part number)
¾ See package dimension on last page
* 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).
