This instrument effectively isolates individual diode branches from the others, allowing accurate capacitance measurement of each branch or each diode. The conditions are: 20 mV R.M.S. voltage at 1 MHz. Avago defines this measurement as “CM”, and it is equivalent to the capacitance of the diode by itself. The equivalent diagonal and adjacent capacitances can then be calculated by the formulas given below. In a quad, the diagonal capacitance is the capacitance between points A and B as shown in the figure below. The diagonal capacitance is calculated using the following formula C1 x C2 + _______ C3 x C4 CDIAGONAL = _______ C1 + C2 C3 C2 C4 C B The equivalent adjacent capacitance is the capacitance between points A and C in the figure below. This capacitance is calculated using the following formula 1 CADJACENT = C1 + ____________ 1 + –– 1 + –– 1 –– C2 C3 C4 This information does not apply to cross-over quad diodes.

The first step in choosing the right product is to select the diode type. All of the products in the HSMS-280x family use the same diode chip, and the same is true of the HSMS-281x and HSMS-282x families. Each family has a different set of characteristics which can be compared most easily by consulting the SPICE parameters in Table 1. A review of these data shows that the HSMS-280x family has the highest breakdown voltage, but at the expense of a high value of series resistance (Rs). In applications which do not require high voltage the HSMS-282x family, with a lower value of series resistance, will offer higher current carrying capacity and better performance. The HSMS-281x family is a hybrid Schottky (as is the HSMS-280x), offering lower 1/f or flicker noise than the HSMS-282x family. In general, the HSMS-282x family should be the designer’s first choice, with the -280x family reserved for high voltage applications and the HSMS-281x family for low flicker noise applications. 0.079 0.039 0.022 Dimensions in inches Figure 6.

Components with a low mass, such as the SOT package, will reach solder reflow temperatures faster than those with a greater mass. 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 reflow zone briefly elevates the temperature sufficiently to produce a reflow 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 reflow zone (TMAX) should not exceed 260°C. Avago’s SOT diodes have been qualified to the timetemperature profile shown in Figure 8. This profile is representative of an IR reflow type of surface mount assembly process. 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 reflow of solder. 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 tp Tp Critical Zone T L to Tp Ramp-up Temperature TL Ts Ts tL max min Ramp-down ts Preheat 25 t 25° C to Peak Time Figure 8.
