What is 1N6114US and what does it protect?
The 1N6114US is a single-channel bidirectional Zener TVS diode from Microchip Technology, designed to clamp transients on signal or power lines. It provides 500W peak pulse power per the 10/1000µs waveform, with a reverse standoff voltage of 16.7V and a maximum clamping voltage of 32.03V at 15.58A peak pulse current. The bidirectional configuration (1 channel) means it can sink both positive and negative transients, making it suitable for AC-coupled or bipolar signal lines where polarity is not fixed.
Temperature range and environment suitability
The 175°C ceiling allows for high-temperature PCB regions near power stages without derating the surge capability. The SQ-MELF package (B, SQ-MELF per supplier device package) provides a hermetic-like glass-passivated body with low thermal resistance to the board, critical for dissipating the 500W pulse without junction runaway.
Lifecycle and supply posture
No successor or cross-reference is listed — this is the current production part. Sourced per RFQ against the BOM quantity. The SQ-MELF package is a standard surface-mount footprint, compatible with reflow assembly processes used in high-reliability builds.
