Overvoltage Spark Gaps

CPI Electron Device Business’s Overvoltage Spark Gaps brochure presents a comprehensive overview of the OGP, PGP, and PB series—ceramic-metal, hermetically sealed switches designed for high-voltage surge protection and fast transient switching. These devices operate across a wide range of 500 V to 100 kV with peak current capabilities up to 50 kA. Ideal for “crowbar” circuit protection and capacitor switching, the OGP series supports both single-shot and repetitive switching, with operational lifespans ranging from 1,000 to over 5 million cycles depending on discharge severity.

The PGP and PB series specialize in high dv/dt conditions, with extremely fast response times. The PB series, designed for printed circuit boards, offers peak currents up to 1.5 kA and nanosecond-level current rise times, making them suitable for compact and space-sensitive environments. Both PGP and PB gaps maintain a dynamic breakdown voltage close to the static breakdown voltage even under rapid transient conditions, enhancing reliability in mission-critical applications.

Key features include fast switching, long operational life, no warm-up time, and high surge handling in compact footprints. The brochure also details comprehensive environmental and electrical specifications, such as operation from -54°C to +100°C, shock resistance up to 50 g, and capacitance as low as 3 pF.

With flexible configuration options and a global reputation for reliability, CPI’s spark gaps provide robust protection for aerospace, defense, industrial, and medical systems. For custom applications or detailed specifications, CPI recommends consulting their technical documentation or engineering support team.
