Microchip MP4KE170A

DESCRIPTION

This family of high-reliability, plastic packaged Transient Voltage Suppressors offer high reliability at an affordable price. Standoff voltage values range from 5.8 to 342 volts and 5% or 10% tolerance options are available. Source control is standard and three increasingly stringent screening options for enhanced reliability are available.

FEATURES

• High reliability controlled devices with wafer fabrication and assembly lot traceability.
• All devices 100% surge tested.
• Optional screening in reference to MIL-PRF-19500 is also available. Refer to High Reliability NonHermetic Product portfolio for more details on Microsemi screening options.
• Moisture classification is level 1 with no dry pack required per IPC/JEDEC J-STD-020B.
• 3σ lot norm screening performed on standby current (ID).
• RoHS compliant versions available.
