The Vishay General Semiconductor - Diodes Division PAR® series P4KA9-1AHE3-73 is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust protection. This device features a reverse standoff voltage of 7.78V and a breakdown voltage of 8.65V (minimum). It provides effective clamping at 13.4V for a peak pulse current (Ipp) of 29.9A, with a peak pulse power rating of 400W. The P4KA9-1AHE3-73 is housed in a DO-204AL (DO-41) axial package, suitable for through-hole mounting. Qualified to AEC-Q101 for automotive applications, it operates within a junction temperature range of -65°C to 185°C. This component is commonly employed in automotive electronics, industrial control systems, and telecommunications equipment where transient overvoltage protection is critical. It is supplied in Tape & Box packaging.
