clamping voltage

clamping voltage

The voltage at which a surge suppressor performs its suppression tasks such as diverting the power line to ground or absorbing the excessive energy. For 120-volt AC power, the clamping voltage is around 135 volts. For 5 volt DC systems, the clamping voltage is typically 7.5 volts.

The four-line, 3.3V RClamp3324P offers designers increased protection margin by offering an exceptionally low ESD clamping voltage while minimizing loading capacitance to protect high-speed data interfaces, including LVDS, Ethernet and USB 3.x.
Vendors offer AV surge protectors with indicator lights, UL rating, clamping voltage, joule rating, response time, and others.
Most whole-house surge suppressors use MOV (metal oxide varistors) components that absorb the electrical energy from the surge when it gets above a certain level (clamping voltage).
The new PAM8S series provides an industry best combination of surpassing ISO 16750-2:2010(E) load dump testing while also delivering an industry-leading lowest clamping voltage at 48.4 volts.
The voltage of the tested input EMP is above the clamping voltage of each protection device.
They support an operating temperature range of -40 ?C to +85 ?C, and each have a clamping voltage of 32 volts (V), which typically is at least thirty times better than existing ceramic solutions.
The device features small 0201 standard package (0.6mmx0.3mm); bi-directional +/- 30kV contact discharge ESD protection per IEC61000-4-2 standard; low clamping voltage of +/- 8.6V; and low dynamic resistance, typically 0.4 Ohm.
Check the technical specifications for these minimum features: 330 volts (or less) clamping voltage, 5 nanoseconds (or less) clamping speed and 500 joules (or more) energy dissipation.
-- 40% reduction in peak clamping voltage -- 15-40% reduction in peak residual current -- 100 Ohm differential impedance matching with no external compensation required -- Straight through routing for improved layout -- Compact 16 pin TDFN package for reduced board space
The proper selection is a function of the performance of the device under transient conditions with an ideal transient voltage suppressor reaching its clamping voltage in zero time.
