SA5.0 – SA170CA
Available
5.0 to 170 Volts, 500 Watts
Transient Voltage Suppressors
DESCRIPTION
This Transient Voltage Suppressor is a high value commercial product that offers protection to
voltage sensitive components. The response time of their clamping action is virtually
instantaneous (less than 100 ps for unidirectional and less than 5 ns for bidirectional). They
have a peak pulse power rating of 500 watts at 10/1000µs as depicted in figures 1 and 2.
They are also virtually identical to power ratings and electrical features of the P5KE5.0 through
P5KE170CA series that had also been earlier defined for this same package.
Important: For the latest information, visit our website http://www.microsemi.com.
FEATURES
Available in both unidirectional and bi-directional construction.
5.0 to 170 volts stand-off voltage availability.
500 watts Peak Pulse Power dissipation.
RoHS compliant versions available.
APPLICATIONS / BENEFITS
Economical series.
Flexible axial-lead mounting terminals.
Quick response.

SYMBOLS & DEFINITIONS
Definition
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK).
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Maximum Zener Surge Current: The non-repetitive peak value of Zener surge current at a specified wave form.
Reverse Voltage: The reverse voltage dc value, no alternating component.
Zener Voltage: The Zener voltage the device will exhibit at a specified current (IZ) in its breakdown region.
Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a
specified rms current modulation (typically 10% of IZT or IZK) and superimposed on IZT or IZK respectively.
