• Manufacturer Part Number: HSMS-2702
• Description: High Performance Schottky Diode for Transient Suppression
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Note: For lead-free option, the part number will have the character "G"
The key factors in these equations
are: R

40°C/W; the thermal resistance of
the iron-alloy-leadframe, SOT-23
package is typically 460°C/W; and
the thermal resistance of the

resistance on the current handling
capability of these diodes can be
seen in Figures 3 and 4. Here the
computed values of junction
temperature vs. forward current
are shown for three values of
ambient temperature. The SOT-
323 products, with their copper
leadframes, can safely handle
almost twice the current of the
larger SOT-23 diodes. Note that
the term “ambient temperature”
refers to the temperature of the
diode’s leads, not the air around
the circuit board. It can be seen
that the HSMS-270B and
HSMS-270C products in the
SOT-323 package will safely
withstand a steady-state forward
current of 550 mA when the

diode’s terminals are maintained
at 75°C.
For pulsed currents and transient
current spikes of less than one
microsecond in duration, the
junction does not have time to
reach thermal steady state.
Moreover, the diode junction may
be taken to temperatures higher
than 150°C for short time-periods
without impacting device MTTF.
Because of these factors, higher
currents can be safely handled.
The HSMS-270x family has the
highest current handling capabil-
ity of any Agilent diode.
