5-channel Zener array in SOT-363 — active production part
The SMF15CT1G from onsemi is a 5-channel unidirectional Zener diode array in a 6-TSSOP / SC-88 / SOT-363 surface-mount package. It is rated for 100W peak pulse power with a 15V reverse standoff voltage, clamping at 29V max under an 8/20 µs pulse of 5A. Capacitance is 33pF at 1MHz, low enough to leave high-speed data lines (USB, HDMI, LVDS) with minimal signal degradation, though the part is not rated for power-line protection — it is a signal-line clamp.
Package and footprint — SOT-363
The SOT-363 (also known as SC-88 or SC-70-6) is a 6-lead package. The small footprint saves board space when protecting multiple signal lines.
