1N5907 and 1N5908
1500 WATT LOW VOLTAGE TRANSIENT
VOLTAGE SUPPRESSOR

DESCRIPTION
APPEARANCE
This pair of unidirectional low voltage Transient Voltage Suppressor (TVS)
devices for the 1N5907 and 1N5908 JEDEC registrations with different
packages have the same high Peak Pulse Power rating of 1500 W with
extremely fast response times. The 1N5907 is available in a military qualified
version 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 surge levels of
IEC61000-4-5 described herein. They are also very successful in protecting
airborne avionics and electrical systems when low voltage is required. Since
their response time is virtually instantaneous, they can also protect from ESD
and EFT per IEC61000-4-2 and IEC61000-4-4.
DO-13
CASE 1
Both hermetic seal and molded types are available.

* 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).
