Duration of applied current < 300ms, duty cycle < 2%. + Utilizing a pulse which decays exponentially to 50% of the peak value in ims. See graph $ Peak Sinusoidal surge current of 8.3ms duration, non-repetitive. APPLICATIONS Voltage transients can be suppressed with series elements, shunt elements, or a combination of both. These elements may be passive or active. For low and medium power applications, a series resistor and zener clamp offer several attractive features: 1. Simplicity of design 2. High reliability 3. Fast response time The 1N5610 series of surge suppressors will suppress the following transients defined by MIL-S-704A without the use of any series limiting resistance beyond that provided by the source: 1. All 600V transients (category #1 on chart below) _ 2. All 80V transients except those generated by the main voltage regulator (category #2 on chart below) 3. The overvoltage transients generated by the main voltage regulator (category #3 on chart below) will also be suppressed by the 1N5610 series if: a. A20 ohm series limiting resistor is used, or b. No series resistance is used but the zener is protected within 500 us by using, for example, an SCR crowbar The above statements are based on the source impedances and dv/dt characteris- tics as given in ARINC* Specification #413. This report entitted Guidance for Aircraft Electrical Power Utilization and Transient Protection serves to further define M/L-STD-704A for large aircraft electrical systems. category | Seurcect |) Maximum | puration | Mn Source | avat 1, Inductive 600 V <10us 50 ohms Switching 2.
