The ESD12VAPH is engineered to protect sensitive equipment against ESD, EFT, and lightning-induced surges in harsh environments. Featuring a 12V reverse working voltage, breakdown range of 13.5–15.5V, and clamping voltage of approximately 17V at 1A and 22–28V at higher surge currents, it supports peak pulse power up to 500W and ±30kV IEC immunity. Its ultra-fast response and strong thermal stability make it ideal for industrial controllers, automotive modules, motor drives, and communication interfaces requiring robust long-term transient protection.
