Automotive-grade transient suppression for 48V rails
The 1.5KE68CAHB0G: It clamps at 92V maximum with a 58.1V reverse standoff voltage, making it suited for protecting 48V nominal DC buses and similar power rails in automotive and industrial systems. AEC-Q101 qualification confirms the device meets automotive-grade stress and reliability requirements, including temperature cycling and ESD robustness, for deployment in engine compartments and chassis-mounted modules.
Clamping parameters and pulse handling
The 1500W peak pulse rating at 10/1000µs waveform covers common surge events like load dump and inductive kickback.
Package and board integration
Housed in a DO-201AA (DO-27) axial-lead package, the device is through-hole mounted with a DO-201 supplier package designation. The axial body suits point-to-point wiring, terminal block assembly, or PCB through-hole layouts where surface-mount TVS diodes are impractical due to thermal or mechanical constraints. The bidirectional configuration (single channel) eliminates orientation concerns during assembly — the device clamps equally on positive and negative transients, simplifying inventory management for unipolar and bipolar rail protection.
