概要
Description
SZ1SMB5915BT3G is a surface‑mount transient-voltage-suppressor (TVS) diode in an SMB (DO-214AA) package. It’s designed to protect low‑voltage power rails (around 5 V) from surge and ESD events by clamping excess voltage quickly while remaining non‑conductive during normal operation. The “5915” and the BT3G suffix indicate the specific voltage rating and RoHS/lead‑free packaging within the SZ1S/SMB TVS family.
Typical use cases include protecting USB/power inputs, data lines, and other 5‑V logic rails in consumer electronics.
For precise electrical specifications (standoff voltage, breakdown and clamping voltages, peak pulse power, leakage, temperature range) and exact packaging details, consult the official datasheet from the manufacturer or trusted distributors (Digi‑Key, Mouser, etc.).
