Microchip M15KP78CA

DESCRIPTION

This Transient Voltage Suppressor series of M15KP22A – M15KP280CA offers an extended voltage range and also provides a variety of high reliability, uni- and bi-directional options as well. RoHS compliant versions are also available. These devices have the ability to clamp dangerous high voltage transients such as secondary effects of lightning strikes, providing circuit protection to several class levels in the IEC61000-4-5 specification. Clamping time is virtually instantaneous. It also provides protection from transients caused by inductive load dumps, RFI, and ESD, providing protection to IEC61000-4-2 and -4-4.

FEATURES

● Available in both unidirectional and bidirectional configurations
● 3σ lot norm screening performed on standby current ID
● 100% surge tested devices
● Suppresses transients up to 15 kW @ 10/1000 s and 100 kW @ 8/20 s (see Figure 1)
● Various screenings in reference to MIL-PRF-19500 are available. Refer to Hirel Non-Hermetic
Product Portfolio for more details on the screening options.
