Overview
The P4SMA series is designed to protect sensitive electronic equipment from voltage transients caused by lightning strikes and other transient voltage events.
Applications
- TVS devices are ideal for protecting I/O interfaces, VCC buses, and other susceptible circuits in telecommunications, computing, industrial, and consumer electronics applications.
Key features
- 400W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycle) of 0.01%
- SMD low-profile surface mount package, minimizing PCB footprint
- Typical failure mode is short circuit due to overvoltage or overcurrent
- Whisker testing per Table 4a and 4c of JEDEC JESD201A, passing Level 1 and Level 2
- IEC 61000-4-2 ESD: 30kV (air), 30kV (contact)
- Glass passivated chip junction
- Low dynamic resistance
- VBR@TJ = VBR@25°C × (1 + G̅T̅ × (T̅J̅ - 25)) (αT: temperature coefficient, typical value 0.1%)
- UL94 V-0 flammability rated approved compound
- Halogen-free and RoHS compliant
- Lead-free E3: second-level interconnect lead-free, terminal finish material tin (Sn) (per IPC/JEDEC J-STD-609A.01)
- Recognized by UL 497B as isolated loop circuit protector
- Products manufactured outside China available (parts with E suffix)
