A simplified example is shown in Fig.7. handbook, full pagewidth keyboard, terminal, printer, etc. A B C D I/O FUNCTIONAL DECODER BZA900A GND MGW316 Fig.7 Computer interface protection. Device placement and printed-circuit board layout Circuit board layout is of extreme importance in the suppression of transients. The clamping voltage of the BZA900A is determined by the peak transient current and the rate of rise of that current (di/dt). Since parasitic inductances can further add to the clamping voltage (V = L di/dt) the series conductor lengths on the printed-circuit board should be kept to a minimum. This includes the lead length of the suppression element. In addition to minimizing conductor length the following printed-circuit board layout guidelines are recommended: 1. Place the suppression element close to the input terminals or connectors 2. Keep parallel signal paths to a minimum 3. Avoid running protection conductors in parallel with unprotected conductors 4. Minimize all printed-circuit board loop areas including power and ground loops 5. Minimize the length of the transient return path to ground 6. Avoid using shared transient return paths to a common ground point. 2001 Sep 03 6 Philips Semiconductors Product specification Quadruple ESD transient voltage suppressor BZA900A-series PACKAGE OUTLINE Plastic surface mounted package; 5 leads SOT665 D E A X Y S S HE 5 4 A 1 2 e1 c 3 bp w M A Lp e detail X 0 1 2 mm scale DIMENSIONS (mm are the original dimensions) UNIT A bp c D E e e1 HE Lp w y mm 0.6 0.5 0.27 0.17 0.18 0.08 1.7 1.5 1.3 1.1 1.0 0.5 1.7 1.5 0.3 0.1 0.1 0.1 OUTLINE VERSION REFERENCES IEC JEDEC EIAJ ISSUE DATE 01-01-04 01-08-27 SOT665 2001 Sep 03 EUROPEAN PROJECTION 7 Philips Semiconductors Product specification Quadruple ESD transient voltage suppressor BZA900A-series DATA SHEET STATUS DATA SHEET STATUS(1) PRODUCT STATUS(2) DEFINITIONS Objective data Development This data sheet contains data from the objective specification for product development.
