The axial form factor allows the body to sit above the board surface, improving convective cooling around the junction during repetitive surge events. The lead spacing matches standard 0.100-inch pitch layouts common in power-supply and telecom protection stages. The bidirectional configuration (single channel) means no polarity marking is needed — the device clamps equally on positive and negative transients, simplifying assembly verification. ## Active lifecycle and sourcing posture No pin-compatible second-source is recorded on this specific order code, but the 1.5KE39 family shares the same DO-201AE footprint and 1500W rating across manufacturers — cross-reference verification is straightforward.","metaTitle":"1.5KE39CA-TP TVS Diode, 1500W, 33.3V Standoff, DO-201AE","metaDescription":"Micro Commercial Co 1.5KE39CA-TP bidirectional TVS, 1500W peak pulse, 33.3V standoff, DO-201AE axial.
