Transient protection for 48V bus lines
The 1.5KE51CA-TP is a 1500W bidirectional TVS diode from Micro Commercial Co designed to clamp transients on DC power rails or signal lines with a nominal operating voltage up to 43.6V. The 48.5V minimum breakdown voltage ensures the device stays off during normal operation, while the 70.1V maximum clamping voltage limits the peak voltage seen by downstream components during a surge event.
1500W peak pulse power in DO-201AE
Rated for 1500W of peak pulse power dissipation (10/1000 µs waveform), this device absorbs substantial transient energy without failing. The DO-201AE axial leaded package supports through-hole mounting on boards where the lead bend and body clearance must be accounted for in the layout. A single bidirectional channel protects AC-coupled or bipolar signal lines without needing two diodes back-to-back, simplifying the BOM and board layout.
Active production, available through distribution
Micro Commercial Co lists the 1.5KE51CA-TP as Active in production, meaning it remains a standard catalog item with ongoing manufacturing support. The base product number 1.5KE51 covers the full family; the -TP suffix denotes the tape-and-reel packaging variant.
