Philips ECG ECG4943, 39.0V DC Surge Clamping, Overvoltage Transient Suppressor, Bidirectional ~ Axial Lead (NTE4943)

The 4900 series of silicon Transient Suppressors designed to protect voltage sensitive components from high energy voltage transients. Transient over voltage suppressor devices have become very important as a consequence of their high surge capability, extremely fast response time, and low incremental surge resistance (Rs).
