Key Features
- 100 J energy absorbing capacity for robust protection against high-energy transient surges
- 21 V RMS maximum circuit voltage rating for low-voltage AC and DC power line protection
- Disk package through-hole design with 23 mm body length for easy PCB and panel mounting
- RoHS-compliant and REACH-compliant construction for global regulatory compliance
Applications
The V33ZA70P is used as a primary transient voltage suppressor in AC power supply inputs, motor drives, and industrial control panels operating below 21 V RMS. Its 100 J energy rating handles repeated lightning-induced or switching transients without degrading clamping performance. The radial leaded through-hole package allows direct board mounting or chassis-level installation in panel-mounted surge protection circuits.

Frequently Asked Questions
How much energy can the V33ZA70P absorb during a single transient surge event?
The V33ZA70P is rated for a maximum energy absorption of 100 J per transient pulse. This capacity is sufficient to clamp 8/20 µs waveform surges commonly caused by lightning strikes or inductive load switching on 21 V RMS circuits without thermal runaway or physical damage to the varistor disk.
What is the maximum continuous AC voltage for safely deploying the V33ZA70P on a power line?
The V33ZA70P supports a maximum circuit RMS voltage of 21 V AC, which corresponds to a peak voltage of approximately 30 V. Using it above this rating risks thermal degradation from continuous current draw. For 24 V AC lines, engineers should select a higher-voltage MOV variant to maintain proper derating margin.
How does the V33ZA70P physically fit in a through-hole PCB design and what lead spacing is typical?
The V33ZA70P uses a disk package body of 23 mm diameter and 26.5 mm height with radial leads. Standard Littelfuse ZA-series disk varistors use 7.5 mm or 10 mm lead pitch, allowing placement in common through-hole PCB holes. Its large disk size accommodates the 100 J energy rating while the radial format suits both vertical and horizontal PCB orientations.
