1N5908RL4

The 1N5908RL4 is a 1500 watt Mosorb Zener transient voltage suppressor (TVS) diode from ON Semiconductor (onsemi). It is designed to protect sensitive electronic components from high-voltage, high-energy transients. The device features a working peak reverse voltage of 5V and a maximum clamping voltage of 8.5V at a peak pulse current of 120A. With a peak pulse power rating of 1500W, it offers robust surge protection. The response time is typically less than 1 ns, providing fast clamping action. The diode is unidirectional and comes in a void-free, transfer-molded DO-201AD axial lead package. It is suitable for through-hole mounting and can operate over a junction temperature range of -65°C to +175°C. The steady-state power dissipation is 5W, and the thermal resistance junction-to-lead is 20°C/W. Typical applications include communication systems, numerical controls, process controls, medical equipment, business machines, and power supplies, where protection of CMOS, MOS, and bipolar integrated circuits is required.
