eee x | _1500 Watt Voidiess (TZS) Transient Zener Suppressors Applications - Overvoitage transient voltage protection against static (ESD), power and lightening. The hard glass voidiess construction is especially suited for the hostile environments in aerospace and military equipment applications where performance and a small footprint are important. BKC can produce generic equivalents to JAN / TX / TXV and JANS levels per MIL-S-19500 / 552 with internal source control drawings. Use HR, HRX, HRV HRS suffixes for cost effective high reliability parts or use your own SCD. Features .
