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. Specification Features

  • 500 mW Rating on FR−4 or FR−5 Board
  • Wide Zener Reverse V oltage Range − 2.4 V to 56 V
  • Package Designed for Optimal Automated Board Assembly
  • Small Package Size for High Density Applications
  • ESD Rating of Class 3 (>16 kV) per Human Body Model
  • Peak Power − 225 W (8 X 20 s) 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 Rating Symbol Max Unit Peak Power Dissipation @ 20 s (Note 1) @ T L ≤ 25°C Ppk 225 Watts Total Power Dissipation on FR−5 Board, (Note 2) @ TL = 75°C Derated above 75°C PD 500 6.7 mW mW/ °C Thermal Resistance − Junction−to−Ambient (Note 3) R JA 340 °C/W Thermal Resistance − Junction−to−Lead (Note 3) R JL 150 °C/W Junction and Storage Temperature Range TJ, Tstg −55 to +150 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. Nonrepetitive current pulse per Figure 11 2.

Tolerance and Voltage Designation: Zener Voltage (VZ) is measured with the Zener Current applied for PW = 1 ms. 6. ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for IZ(AC) = 0.1 IZ(DC), with the AC frequency = 1 kHz.
