DO-214AB (SMC)

      1.5SMC Series have many  kinds of products, and we take DO-214AB (SMC) for example. DO-214AB (SMC) could be used in sensitive electronics protection against voltage transients induced by inductive load switching and lighting on ICs, MOSFET, signal lines of sensor units for consumer, computer, industrial, automotive and telecommunication.
      All of DO-214AB (SMC) have the following features:1. Low profile package; 2. Ideal for automated placement; 3. Glass passivated chip junction; 4. Available in uni-directional and bi-directional; 5.1500 W peak pulse power capability with a 10/1000 µs waveform, repetitive rate (duty cycle): 0.01 %; 6.Excellent clamping capability; 7.Very fast response time; 8. Low incremental surge resistance; 9. Meets MSL level 1, per -STD-020, LF maximum peak of 260 °C; 10.Solder dip 260 °C, 40 s; 11. Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC.
      Here are some manchnical data of DO-214AB (SMC) :Molding compound meets UL 94 V-0 flammability rating, Base P/N-E3 - RoHS compliant, commercial grade. Base P/NHE3 - RoHS compliant, high reliability/automotive grade (AEC Q101 qualified). Terminals: Matte tin plated leads, solderable per J-STD-002 and JESD22-B102 E3 suffix meets JESD 201 class 1A whisker test, HE3 suffix meets JESD 201 class 2 whisker test Polarity: For uni-directional types the band denotes cathode end, no marking on bi-directional types.
      When TA = 25 °C unless otherwise noted, maximum rating: 1. Peak power dissipation with a 10/1000 µs waveform (1)(2) (PPPM) is 1500W; 2. Peak pulse current with a 10/1000 µs waveform (1)(IPPM) is See next table. 3. Power dissipation on infinite heatsink TA = 50 °C (PD) is 6.5 W; 4. Peak forward surge current 8.3 ms single half sine-wave uni-directional only (2)(IFSN)is 200 A; 5.Operating junction and storage temperature range (TJ, TSTG) is - 65 to + 150°C. the notes are (1) Non-repetitive current pulse, per Fig. 3 and derated above TA = 25 °C per (2) Mounted on 0.31 x 0.31" (8.0 x 8.0 mm) copper pads to each terminal.
