SCHOTTKY RECTIFIERS (continued) There are many other standard features in Motorola Schottky rectifiers that give added performance and reliability. 1. GUARDRINGS are included in all Schottky die for reverse voltage stress protection from high rates of dv/dt to virtually eliminate the need for snubber networks. The guardring also operates like a zener and avalanches when subjected to voltage transients. 2. MOLYBDENUM DISCS on both sides of the die minimize fatigue from power cycling in all metal product. The plastic TO-220 devices have a special solder formulation for the same purpose. 3. QUALITY CONTROL monitors all critical fabrication operations and performs selected stress tests to assure constant processes. lo, AVERAGE FORWARD RECTIFIED CURRENT (A) 15 16 20 25 30 CASE 56-02 221B-01 221A-02 6-02 221A-02 11-03 340-01 Plastic Plastic Metal Plastic Metal p- fe y |} - o tt : f aes / Y VARM ~~ Do4 T0220AC T0220AB* T0220AB8 T03* TO0-21BAC* 20 1N5826 1N5829 30 1N5827 1N5830 1N6095 35 MBR1635 | MBR2035CT MBR2535CT | MBR3035CT | MBR3035PT 40 1N5828 1N5831 IN6096 $D241 45 MBR1645_ | MBR2045CT MBR2545CT | MBR3045CT | MBR3045PT IFSM (A) 500 300 150 800 400 300 400 200 Tj or Tc at rated yess 80 125 135 lo (C) 85 70 125 105 Tj MAX 125 150 150 125 150 150 150 150 BARRIER METAL; CHROME PLATINUM CHROME PLATINUM Ve MAX at lo (V) -50 -60 72 48 58 73 .65 72 (*) lo is total device output.
