SILICON SURGE ABSORBER @ OKAYA M

RSSA

The Silicon Surge Absorber is available in five series that support the countermeasure against a wide range of surge from low to high, including electrostatic discharges and lightning surges. The device may also be used as a constant voltage device where high voltage or high power is required.

• Breakdown Voltage (Vbr)

Voltage at which avalanche current may begin to flow, normally the voltage between the surge absorber's leads when 1mA of current is applied.

* Standoff Voltage (Vwm)

A maximun voltage that can be applied to the surge absorber continuously.

• Reverse Leakage Current (Ir)

A maximum current flowing through the surge absorber when the standoff voltage is applied to the surge absorber.

* Peak Surge Current (I ppm )

A maximum surge current that can flow through the surge absorber, but not repetitively. The waveforn in the table is 8/20p,sec.

* Peak Clamp Voltage (Vcl)

a maximum voltage that may be generated between the surge absorber's leads when the peak surge current is applied to the surge absorber.

• Mavimum Allowable Power (Pppm )

(Pppm)= (Vppm)x (Vcl)

• Fast response to rapid surge (1fJ-¹²sec).

• Almost no performance degradation against repetitive surge.

• Very low internal resistance during operation.

• Very small leak current.

• Mesa chip design provides high invulnerability to impulse surges.
