Description/Applications

The HSMP-382x series is optimized for switch ing ap-

plications where ultra-low resistance is required. The

HSMP-482x diode is ideal for limiting and low induc-

tance switching applications up to 1.5 GHz.

A SPICE model is not available for PIN diodes as SPICE

does not provide for a key PIN diode characteristic, carrier

lifetime.

Microstrip Series Connection for HSMP-482x Series

In order to take full advantage of the low inductance

of the HSMP-482x series when using them in series

applications, both lead 1 and lead 2 should be connected

together, as shown in Figure 14.

Figure 16. Equivalent Circuit.

Co-Planar Waveguide Shunt Connection for HSMP-482x Series

Co-Planar waveguide, with ground on the top side of

the printed circuit board, is shown in Figure 17. Since

it eliminates the need for via holes to ground, it o ers

lower shunt parasitic inductance and higher maximum

attenuation when compared to a microstrip circuit. See

AN1050 for details.

Microstrip Shunt Connections for HSMP-482x Series

In Figure 15, the center conductor of the microstrip line

is interrupted and leads 1 and 2 of the HSMP-482x diode

are placed across the resulting gap. This forces the 0.5

nH lead inductance of leads 1 and 2 to appear as part of

a low pass  lter, reducing the shunt parasitic inductance

and increasing the maximum available attenuation.

The 0.3 nH of shunt inductance external to the diode

is created by the via holes, and is a good estimate for

0.032" thick material.

SMT Assembly

Reliable assembly of surface mount components is a

complex process that involves many material, process,

and equipment factors, including: method of heating

(e.g., IR or vapor phase re ow, wave soldering, etc.) circuit

board material, conductor thickness and pattern, type of

solder alloy, and the thermal conductivity and thermal

mass of components. Components with a low mass, such

as the SOT-323/-23 package, will reach solder re ow

temperatures faster than those with a greater mass.

Avago’s diodes have been quali ed to the time-

temperature pro le shown in Figure 21. This pro le is

representative of an IR re ow type of surface mount

assembly process.

After ramping up from room temperature, the circuit

board with components attached to it (held in place with

solder paste) passes through one or more preheat zones.

The preheat zones increase the temperature of the

board and components to prevent thermal shock and

begin evaporating solvents from the solder paste. The

re ow zone brie y elevates the temperature su ciently

to produce a re ow of the solder.

The rates of change of temperature for the ramp-up and

cool-down zones are chosen to be low enough to not

cause deformation of the board or damage to components

due to thermal shock. The maximum temperature in the

re ow zone (TMAX) should not exceed 260°C.

These parameters are typical for a surface mount

assembly process for Avago diodes. As a general

guideline, the circuit board and components should be

exposed only to the minimum temperatures and times

necessary to achieve a uniform re ow of solder.
