In the United States, telephone manufacturers achieve this compensation with silicon carbide varistors that consume any excess current from a short loop (see fig. 2). ❋ Cameron, J.M. (1980)
Highlights of Vishay's line of resistors will include high-voltage devices, Power Metal Strip® resistors, wirewound resistors for pulsing applications, stainless steel crowbar devices, AEC-Q200-qualified thin film resistors, metal oxide high-surge varistors for transient and overvoltage protection applications, and mini lug temperature sensors for power electronics thermal management applications.
VSH - News, we are advised by the company that varistors and temperature sensors were incorrectly listed among the inductor products on view in Vishay's exhibit at APEC 2012.
In the corrected version, the varistors and temperature sensors are listed among the resistor products on view.

Maxim Integrated Products MAX14527 and MAX14528: Overvoltage protectors guard against 28V faults Texas Instruments TPS2552 / 3: Power-distribution switches have high accuracy On Semiconductor NP0080, NP0120, and NP0160: Thyristor-surge-protection devices have low capacitance AVX Corp UltraGuard: Multilayer ceramic varistors have low leakage current OnChip Devices OC1214-01TR: Diode array protects RF antennas from ESD events VPT VPTi10-28: EMI-filter and transient-suppression module meets avionics, military specifications
Note also that both the clamping voltage and the residual current are much higher with varistors.
ESD diodes and suppressor/varistors have different performance.
