500 mW Rating on FR−4 or FR−5 Board
Wide Zener Reverse Voltage Range − 1.8 V to 43 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
We declare that the material of product
compliance with RoHS requirements.
Mechanical Characteristics:
CASE: Void-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 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.
