2000 Volt & 3000 Volt PIN Diodes

MA4PK200X & MA4PK300X

Rev. 10

Features

Description

M/A-COM Technology Solutions KILOVOLT™ PIN

diode series utilize modern semiconductor and

packaging technology that assures low loss, low

distortion, and reliable performance in multi-kilowatt

switch applications at frequencies as low as 1 MHz.

The PIN chips employed have low resistance, high

power dissipation and very high stand-off voltage

capability. KILOVOLT™ PIN diodes employ ultra high

resistively, long carrier lifetime, float zone material

onto which P+ and N+ regions are deposited using an

epitaxial process designed by M/A-COM Technology

Solutions for high voltage PIN diodes. This process

results in better preservation of the carrier lifetime and

superior layer to layer interface when compared to a

conventional double diffused process. The processing

of the I-region width is tightly controlled using modern

lapping techniques. KILOVOLT™ PIN diode chips

utilize M/A-COM Technology Solutions proprietary

Cermachip™ glass passivation. The hard glass covers

all exposed junction and intrinsic surfaces. This results

in a hermetically sealed, passivated chip that has been

used in many high reliability military and commercial

programs.

Applications

The KILOVOLT™ PIN diode series is designed for use

as high power switching elements in multi-kilowatt HF

and VHF applications. These PIN diodes have been

extensively characterized for their electrical and

thermal properties to assure predictable, low loss, high

power handling and low distortion performance. Some

typical applications are as follows:

 Filter Switches

 Antenna Couplers

 Power Amplifier By-pass Switches

 MRI Switches

Packaging

The metal-ceramic packages were developed

specifically for the KILOVOLT™ PIN diode series.

The packages are designed to withstand extremely

high voltages and currents. The packages meet the

environmental requirements of MIL-STD-202 and

MIL-STD750. The PIN diode chip is bonded to the

package and the anode strap is bonded to the chip

at temperatures exceeding 300°C. The anode strap

has a unique, large cross-sectional area allowing

for high current carrying capability. The packages

are sealed using a projection welding technique in

an inert environment. KILOVOLT™ PIN diodes are

available with a solder lug on the anode electrode

to allow for a convenient and reliable wrap-around
