LMSZ4678T1G Datasheet, PDF (1/6 Pages) Leshan Radio Company – 500 mW SOD−123 Surface Mount

LESHAN RADIO COMPANY, LTD.
Zener Voltage Regulators
500 mW SOD−123 Surface Mount
Three complete series of Zener diodes are offered in the convenient,
surface mount plastic SOD−123 package. These devices provide a
convenient alternative to the leadless 34−package style.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
1. FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint.
2. Thermal Resistance measurement obtained via infrared Scan Method.
