Bourns® Bidirectional Power TVS Diode – PTVS2-xxxC-H SeriesHigh Current PTVS Diodes in an Industry-First Surface Mount DFN Package

INTRODUCTION

Bourns is pleased to announce the new
Model PTVS2-xxxC-H series bidirectional
Power Transient Voltage Suppressor (PTVS)
diodes, capable of handling 2 kA (8/20 μs)
surge current as per IEC 61000-4-5. As theworld's first PTVS devices in a compact
surface mount DFN package, eight RoHScompliant* models are available with amaximum repetitive standoff voltage (VWM)
between 22 V and 86 V.

FEATURES

BENEFITS• 2 kA, 8/20 µs surge-handling capability• Surface mount DFN package• Excellent performance over temperature

MARKET TRENDS

Reliable protection is increasingly requiredagainst high energy surge events in PoE ports,
Remote Radio Units (RRUs), BaseBand Units(BBUs) and high-power DC bus applications.
Bourns has designed its entire PTVS2-xxxC-H
portfolio to meet or exceed IEC 61000-4-5
Level 4 (2 kV, 2 kA) requirements. This new PTVS
series, in a DFN package, is engineered to satisfy
customer needs for a cost-efficient and compact
2 kA option.

APPLICATIONSBourns® PTVS diodes are built using
semiconductor technology, deliveringenhanced surge protection and high reliability
for rated surges compared to an equallysized MOV. The block diagram shown above
illustrates using Model PTVS2-076C-H in a
Remote Radio Unit (RRU) application.

In the circuit above, Bourns® Model PTVS2076C-H is able to withstand a 2 kA surge
under 8/20 μs conditions and has a maximum
working voltage of 76 V. The compact 8 mm x6 mm x 2.5 mm DFN package provides a spacesaving option for today’s dense board designs,
and is capable of replacing larger legacy
through-hole PTVS devices where space-saving
and/or automated pick-and-place assembly isdesired.
