These elements may be passive or active. For low & medium power applications, a series resistor & zener clamp offer several attractive features: 1. Simplicity of design. 2. High reliability. 3. Fast response time. The 1N5610 series will suppress the following transients (defined by MIL-S-704A) without using any series limiting resistance; (except as noted in line #3 below) 1. All 600 V transients (category 1 in chart below). 2. All 80 V transients except those generated by the main voltage regulator (category 2 in chart below). 3. Over-voltage transients from the main voltage regulator (category 3 in chart below) will be suppressed if: a. A 20 ohm series limiting resistor is used, orb. No series resistance is used & the zener is protected within 500 µ s, using (for example) an SCR crowbar. The above statements are based on the source impedances & dv/dt characteristics as given in ARINC* spec# 413; entitled “Guidance for Aircraft Electrical Power Utilization & Transient Protection. This report further defines MIL-STD-704A in regard to large aircraft electrical systems. These surge suppressors are useful in a varierty of other applications where semiconductor devices must function in an environment subject to extremely high, but short term surges. * ARINC stands for Aeronautical Radio Incorporated; Annapolis, Maryland 21401 MSC1061.PDF 5-21-99 Category # Source of Trans.
