DESCRIPTION
This Transient Voltage Suppressor (TVS) series for 1N6358 through 1N6372 are JEDEC registered
selections for both unidirectional and bidirectional devices. The 1N6358 through 1N6364 are
unidirectional and the 1N6366 through 1N6372 are bidirectional where they all provide a very low
specified clamping factor for minimal clamping voltages (V
C
) above their respective breakdown
voltages (V
BR
) as specified herein. They are most often used in protecting sensitive components
from inductive switching transients 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.

Notes:
1. When mounted on FR4 PC board with 4 mm
2
copper pads (1 oz) and track width 1 mm, length 25 mm.
2. At 10/1000
µs
with repetition rate of 0.01% or less (see
figures 1, 2, & 4).
3. At 3/8 inch (10 mm) from body (see derating in
figure 5).
TVS devices are not typically used for dc
power dissipation and are instead operated at or less than their rated standoff voltage (V
WM
) except for
transients that briefly drive the device into avalanche breakdown (V
BR
to V
C
region).

SYMBOLS & DEFINITIONS
Definition
Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition.
o
Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25 C.
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 (α
V(BR)
).
Peak Pulse Current: The peak current during the impulse. (See
figure 2)
Peak Pulse Power: The pulse power as determined by the product of V
C
and I
PP
.
Standby Current: The current at the standoff voltage (V
WM
).

NOTE 1:
TVS devices are normally selected according to the reverse “standoff voltage” (V
WM
) which should be equal to or greater than the DC or
continuous peak operating voltage level.
* The minimum breakdown voltage as shown takes into consideration the + volt tolerance normally specified for power supply regulation on
most integrated circuit manufacturers data sheets. Similar devices are available with reduced clamping voltages where tighter regulated
power supply voltages are employed.
