Key Features
- 14V DC maximum continuous voltage with 33V clamping at 8/20µs pulse for precise transient suppression
- 5.4J energy absorbing capacity handles repetitive surge events without degradation
- Flame-proof surface-mount construction in a compact 5.7×2.5mm rectangular body for automated PCB assembly
Applications
The B72540T0110K062 is designed to clamp transient overvoltages on low-voltage DC and AC signal lines in consumer electronics, industrial control interfaces, and telecommunications equipment. Its 11V RMS rating and 5.4J energy capacity make it suitable for protecting microcontroller I/O ports, sensor inputs, and power-supply input rails from electrostatic discharge and line surges. The surface-mount flame-proof package enables compact, high-density PCB layouts that meet safety compliance requirements.

Frequently Asked Questions
What is the clamping voltage of the B72540T0110K062 under an 8/20µs surge pulse?
The B72540T0110K062 clamps transients to a maximum of 33V under an 8/20µs surge waveform, which is the standard test pulse for surge immunity. This 33V clamp level ensures that downstream components rated above 33V remain protected during typical ESD and line-surge events on 11V RMS signal or power lines.
How much energy can the B72540T0110K062 absorb, and what surge scenarios does that cover?
The B72540T0110K062 absorbs up to 5.4J of energy per surge event. This capacity is sufficient for IEC 61000-4-5 Level 2 surge tests (0.5 kV/1 kV) on signal lines and covers typical ESD surges defined by IEC 61000-4-2. Repeated surges within the rated energy budget do not degrade the varistor's clamping characteristics.
Which PCB footprint and mounting style does the B72540T0110K062 use, and does it fit standard pick-and-place assembly?
The B72540T0110K062 uses a surface-mount rectangular package measuring 5.7mm long by 2.5mm high, compatible with standard SMT pick-and-place equipment and reflow soldering. The flame-proof body construction meets UL and IEC safety standards, making it suitable for consumer and industrial boards where flammability ratings are required without adding discrete fusing components.
