Overview
The EPCOS – TDK Electronics B72220S0950K101 is a high-energy disc varistor designed for robust transient voltage suppression. Its primary function is to protect sensitive electronic components from damaging voltage spikes by shunting excess current. A critical design consideration is the trade-off between its surge current capability (6.5 kA) and its capacitance (2500 pF @ 1 kHz); while high surge handling is essential for power line protection, the inherent capacitance can impact high-frequency signal integrity, necessitating careful placement and potential filtering in sensitive RF applications.
Key Features
- Maximum AC Voltage Rating: 95 V
- Maximum DC Voltage Rating: 125 V
- Peak Surge Current: 6.5 kA (8/20µs)
- Energy Absorption: 50 J
- Capacitance: 2500 pF @ 1 kHz
- Package: 20mm Disc, Through Hole Mounting
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- AC power line surge protection for industrial equipment
- DC power bus transient clamping in automotive electronics
- Protection against lightning-induced surges in telecommunications infrastructure
- Overvoltage mitigation for consumer electronics power supplies
