LC6.5 thru LC170A, e3

1500 WATT LOW CAPACITANCE

TRANSIENT VOLTAGE SUPPRESSOR

DESCRIPTION

APPEARANCE

This hermetically sealed Transient Voltage Suppressor (TVS) product family

includes a rectifier diode element in series and opposite direction to achieve low

capacitance performance below 100 pF (see Figure 2). The low level of TVS

capacitance may be used for protecting higher frequency applications in inductive

switching environments or electrical systems involving secondary lightning effects

per IEC61000-4-5 as well as RTCA/DO-160D or ARINC 429 for airborne

avionics. With virtually instantaneous response, they also protect from ESD and

EFT per IEC61000-4-2 and IEC61000-4-4. If bipolar transient capability is

required, two of these low capacitance TVS devices may be used in parallel in

DO-13

(DO-202AA)

opposite directions (anti-parallel) for complete ac protection as shown in Figure 4.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

MAXIMUM RATINGS

MECHANICAL AND PACKAGING

• 1500 Watts at 10/1000 μs with repetition rate of 0.01% or

•

CASE: DO-13 (DO-202AA), welded, hermetically

sealed metal and glass

less* at lead temperature (T_L) 25^oC (see Figs. 1, 2, & 4)

• Operating & Storage Temperatures: -65^oto +175^oC

•

FINISH: All external metal surfaces are Tin-Lead

plated and solderable per MIL-STD-750 method 2026

• THERMAL RESISTANCE: 50^oC/W (Typical) junction to

lead at 0.375 inches (10 mm) from body or 110 ^oC/W

junction to ambient when mounted on FR4 PC board with

4 mm²copper pads (1 oz) and track width 1 mm, length

25 mm

POLARITY: Cathode connected to case as shown by

diode symbol (cathode positive for normal operation)

•

MARKING: Part number and polarity diode symbol

WEIGHT: 1.4 grams. (Approx)

• DC Power Dissipation*: 1 Watt at T_L< +125^oC 3/8” (10

mm) from body (see derating in Fig 3 and note below)

• Solder Temperatures: 260 ^oC for 10 s (maximum)

TAPE & REEL option: Standard per EIA-296 (add

“TR” suffix to part number)

•

See package dimension on last page

* TVS devices are not typically used for dc power dissipation and are instead operated < V_WM(rated standoff voltage) except for transients that briefly

drive the device into avalanche breakdown (V_BRto V_Cregion) of the TVS element. Also see Figures 3 and 4 for further protection details in rated peak

pulse power for unidirectional and bidirectional configurations respectively.
