MAIN APPLICATIONS
Dedicated to dataline protection, this device provides a tripolar protection function. It ensures the
same protection capability with the same breakdown voltage in both common and differential
modes.
DESCRIPTION
The TPN3021 is a low capacitance transient
surge arrestor designed for protection of high
debit rate communication network. Its low capacitance avoids distorsion of the signal as it
has been designed for T1/E1 and Ethernet networks.
BENEFITS
Trisil technology is not subject to ageing and provides a fail safe mode in short circuit for a better
protection. They are used to help equipment to
meet main standards such as UL1950, IEC950 /
CSA C22.2 and UL1459. They have UL94 V0 approved resin. SO8 package is JEDEC registered.
Trisils comply with the following standards
GR-1089 Core, ITU-T-K20/K21, VDE0433,
VDE0878, IEC61000-4-2.

TEST PROCEDURE :
Pulse test duration (tp = 20ms):
- For bidirectional devices = switch K is closed
- For unidirectional devices = switch K is open
Vout selection
- Devices with Vbo < 200V: Vout = 250VRMS, R1 = 140Ω
- Devices with Vbo > 200V: Vout = 480VRMS, R2 = 240Ω

D.U.T
This is a GO-NOGO test which allows to confirm the holding current (IH) level in a functional test circuit.
Test procedure:
1- Adjust the current level at the IH value by short circuiting the DUT.
2- Fire the DUT with a surge current IPP = 10A, 10/1000 µs.
3- DUT must come back in off state within maximum 50ns.
