Microchip Technology MSMLJ18A

DESCRIPTION

The MSMLG(J)5.0A through MXLSMLG(J)170A series of high-reliability Transient Voltage Suppressors (TVSs) protect circuits from voltage spikes containing up to 3000 W (10/1000 µs model pulse. The SMLG gull-wing design in the DO-215AB package allows for visible solder connections. The SMLJ J-bend design in the DO-214AB package allows for greater PC board mounting density. Selections include unidirectional and bidirectional as well as RoHS compliant versions. These are available with a variety of upscreening options for enhanced reliability. They protect against the secondary effects of lightning per IEC61000-4-5 and against voltage pulses from inductive switching environments and induced by RF radiation. Since their response time is virtually instantaneous, they can also be used in protection from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

FEATURES

• High reliability devices with fabrication and
assembly lot traceability for all M prefix devices
• All devices are 100% surge tested
• 3σ lot norm screening performed on standby current (ID) for all M prefix devices
• Available in both unidirectional and bidirectional versions
• Moisture classification is “Level 1” with no dry pack required
per IPC/JEDEC J-STD-020B for all M prefix devices.
• Enhanced reliability screening options with M prefix are available
in reference to MIL-PRF-19500.
Refer to High Reliability Up-Screened Plastic Products Portfolio
for more details on the screening options.
(See part nomenclature for all available options.)
• RoHS compliant versions available
• Axial-lead equivalent packages for thru-hole mounting are available
as M5KP5.0A to M5KP110CA with 5000 W rating
(contact Microsemi for other surface mount options).
