Breakdown is guaranteed between 95 V and the 137 V maximum clamping point at the peak pulse current. That 42 V window between standoff and clamp gives the designer room to place the TVS after a fuse or a series resistor without the let-through voltage exceeding the downstream device's abs-max rating. The 1500 W rating is the headline figure, but the real-world clamping voltage depends on the actual surge current — the datasheet's V-I curve shows the clamp voltage at a fraction of the peak current is lower than the 137 V max. For a 24 V system this part is overkill; it belongs on 48 V telecom rectifiers, 60 V industrial bus supplies, or battery strings where the nominal rail sits below 85 V. ## DO-201AE axial — the through-hole package that survives repeated surge events The DO-201AE axial leaded package is a glass-passivated junction in a molded epoxy body, rated for continuous junction temperatures from -55 °C to 175 °C. That 175 °C Tj(max) is typical for silicon TVS diodes and means the part can absorb multiple surge events in quick succession as long as the average junction temperature stays below the limit — a single 1500 W pulse raises the die temperature by roughly 100 °C, so the repetition rate is limited by the thermal time constant of the leaded package and the PCB copper. Through-hole mounting on a 48 V power supply board means the axial leads are bent and inserted into plated through-holes — the lead diameter and hole size should follow the IPC-2222 land pattern for DO-201AE, with the body offset a few mm above the board to allow conformal coating flow underneath. The package itself is not hermetic, but the epoxy body meets the standard moisture sensitivity level for a molded device. ## Active production — no last-time-buy pressure The base product number 1.5KE100 covers both unidirectional and bidirectional variants; the CA suffix marks this as the bidirectional version with a single die that clamps both polarities. If the circuit only needs protection against positive transients with a ground reference, the unidirectional version (no CA suffix) has a lower clamping voltage for the same standoff because the Zener breakdown is in one direction only.","metaTitle":"Micro Commercial Co 1.5KE100CA-TP TVS Diode, 1500W","metaDescription":"1.5KE100CA-TP bidirectional TVS diode, 85.5V standoff, 1500W peak pulse power, DO-201AE axial package.
