1500 W peak pulse — the clamping ceiling that decides circuit survival
The 1.5KE62CA-E3/73: That 85 V clamp is the hard ceiling a downstream IC sees during a transient — if the protected rail is a 48 V telecom bus or a 53 V nominal supply, the margin between rail tolerance and clamp voltage is what keeps the board alive.
Breakdown window and temperature envelope
Minimum breakdown voltage is 58.9 V, setting the threshold where the device begins to conduct avalanche current. The reverse standoff of 53 V is the continuous DC rail voltage the diode can sit across without degrading — a 48 V supply with 5 % tolerance stays comfortably below this level. The wide Tj max of 175 °C means the device absorbs the rated 1500 W pulse without derating at elevated ambient, as long as the average power stays within the thermal limits of the DO-201AA package.
The DO-201AA (also known as DO-27) axial-lead through-hole package is the standard for 1.5 kW TVS diodes. Lead spacing and body diameter match legacy footprint patterns, and the axial leads handle manual or wave-solder insertion into plated through-holes on single-layer or multi-layer boards. The 1.5KE package marking is the supplier device code.
Active production — current lifecycle for a long-running TransZorb series
The TransZorb series has been in continuous production for decades, and the 1.5KE62CA-/73 remains a current, orderable line item.
