概要
Description
5.0SMDJ16A is a 5V-rated surface-mount TVS diode (SMDJ series) used to clamp transient voltages on a 5V rail. The "16A" indicates its peak pulse current rating of about 16 A. It is available in the SMDJ (DO-214AB) package and can be unidirectional or bidirectional depending on variant. It protects circuits from inductive switching, ESD, and other surges; common uses include USB, data lines, and 5V logic supplies. When selecting: ensure the working standoff voltage (VRWM) is slightly above normal operation, the peak pulse current rating covers the expected surge, and the clamped voltage stays within your devices’ limits. Proper mounting close to the protected node and appropriate PCB layout are important; use the correct reverse orientation and follow reflow guidelines. Note: values vary by manufacturer; consult the datasheet for VRWM, VBR, Vclamp, and package variant.
Equivalent
5.0SMDJ16A is a 5.0 V standoff TVS diode in the SMDJ package with 16 A peak pulse current. Equivalents are other 5.0 V TVS diodes in the SMDJ family from major brands (Vishay, Littelfuse, Bourns, ProTek, ST). For exact substitutes, use brand cross-reference tools (search 5.0 SMDJ16A or 5.0 V SMDJ) and compare Vrm, Vclamp, and package.
