Housed in the DO-204AC (DO-15) axial-lead package, it mounts through-hole and suits point-of-use transient suppression on power entry boards, industrial control inputs, and telecom rectifier outputs where the 1.1 A peak pulse current (Ipp) at 548 V clamping is sufficient for secondary-side protection. ## Clamping voltage and temperature envelope For a 380 VDC bus, this clamping margin of ~168 V above the standoff gives the downstream MOSFETs or capacitors enough headroom to survive without avalanche breakdown, provided their Vds or Vr ratings exceed 548 V. The 175°C TJ max means the device can be placed near hot components or in sealed enclosures without derating the peak pulse power at elevated ambient — the 600 W rating holds up to 25°C, then derates linearly per the datasheet curve. ## Active lifecycle and sourcing posture The bidirectional configuration (single device replaces two unidirectional diodes in anti-series) simplifies PCB layout and reduces component count on the rail.","metaTitle":"P6KE400CA-B Diodes Inc TVS, 600W, 342V, DO-15","metaDescription":"P6KE400CA-B bidirectional Zener TVS, 600W peak pulse, 342V standoff, DO-15 axial.
