The 1.5KE13AHE3_B/C: The 11.1 V reverse standoff is the maximum DC voltage the TVS can hold without conducting appreciable leakage — it sits on a 12 V battery line with margin. The 12.4 V minimum breakdown means the device starts clamping before the rail reaches 13 V, protecting downstream electronics rated for 16 V abs-max. The 18.2 V maximum clamping at 86 A is the worst-case voltage the load sees during a 10/1000 µs surge event.
Automotive qualification and compliance
AEC-Q101 qualification means this TVS diode has passed the stress tests (temperature cycling, HTRB, H3TRB, ESD) required for automotive-grade semiconductor components. The part is also listed for telecom applications, reflecting its use in 12 V telecom rectifiers and base-station power supplies.
Package and mounting note
Housed in a DO-201AA (DO-27) axial-lead through-hole package. The 1.5KE series uses a glass-passivated junction in a molded case. The axial leads require a 1.0 mm diameter hole in the PCB; the body diameter is about 5.3 mm, with a lead spacing of 8.9 mm typical. The through-hole form factor is preferred for high-reliability and high-temperature environments where surface-mount solder joints may fatigue under thermal cycling.
