Active production — 1500 W bidirectional transient suppressor
The 1.5KE27CA A0G: It clamps transients at 37.5 V maximum, with a 23.1 V reverse standoff voltage — meaning the protected DC rail can sit at 23.1 V continuously without the diode conducting leakage.
Breakdown, clamp, and thermal envelope
Minimum breakdown voltage is 25.7 V, ensuring the diode starts conducting before the protected circuit's absolute-max rating is reached. The 42 A peak pulse current (10/1000 µs) at the 37.5 V clamp level defines the surge capacity — useful for sizing the TVS against expected transient energy in industrial or automotive 24 V bus applications.
DO-201 axial package — through-hole board fit
Housed in the DO-201AA (DO-27) axial-lead package, the diode mounts through-hole and requires a 0.052-inch diameter lead hole on the PCB. The axial form factor is standard for high-power transient suppressors — the leads carry the 42 A surge without trace heating at the board interface.
