With a peak pulse power rating of 1500 W and a clamping voltage of 33.3 V at 45 A, it protects downstream silicon from surges without needing a series fuse or additional steering diodes. ## Voltage window and surge current Breakdown occurs at 22.8 V minimum, ensuring the diode remains off below the rail tolerance. The 33.3 V clamp ceiling limits the voltage the protected load sees during a 45 A pulse — a critical number for selecting downstream capacitor voltage ratings and MOSFET Vds margins. The bidirectional structure means polarity-insensitive installation: either lead can connect to the rail or ground, which simplifies PCB layout for AC-coupled or floating supplies. ## Thermal range and package realities The B Axial through-hole package requires a drilled hole and solder wave — not a reflow footprint — so factor in manual assembly or selective solder for prototype runs. ## Production status and sourcing posture Listed as Active with no announced EOL or NRND notice. Microchip continues to manufacture the 1N6151A in the B Axial package.
