MMSZ5221BT1 Series

Preferred Device

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.

Features

?500 mW Rating on FR?4 or FR?5 Board

?Wide Zener Reverse V oltage Range ? 2.4 V to 110 V ?Package Designed for Optimal Automated Board Assembly ?Small Package Size for High Density Applications ?General Purpose, Medium Current

?ESD Rating of Class 3 (>16 kV) per Human Body Model

?Pb?Free Packages are Available

Mechanical Characteristics

CASE:V oid-free, transfer-molded, thermosetting plastic case FINISH:Corrosion resistant finish, easily solderable

MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES: 260°C for 10 Seconds

POLARITY:Cathode indicated by polarity band FLAMMABILITY RATING:UL 94 V?0

MAXIMUM RATINGS

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.

See specific marking information in the device marking column of the Electrical Characteristics table on page 3 of this data sheet.

ELECTRICAL CHARACTERISTICS (T A = 25°C unless

otherwise noted, V

= 0.95 V Max. @ I = 10 mA)

4.Nominal Zener voltage is measured with the device junction in thermal equilibrium at T L = 30°C $1°C.

5.Z ZT and Z ZK are measured by dividing the AC voltage drop across the device by the ac current applied.

The specified limits are for I Z(AC) = 0.1 I Z(dc) with the AC frequency = 1 KHz.
