Device identity and protection profile
The SMBJ75CE3/TR13: It is a single bidirectional channel device rated for general-purpose circuit protection. With a 75 V reverse standoff voltage (VRWM), the diode remains transparent to the protected line up to that DC level, then begins to avalanche at a minimum breakdown voltage of 83.3 V. For repetitive transients, derate per the pulse derating curve in the datasheet.
Package and board integration
Housed in the DO-214AA (SMB) surface-mount package, the SMBJ75CE3/TR13 occupies a standard footprint with a 0.050-inch (1.27 mm) pitch between the anode and cathode pads. The package body is 4.57 mm long by 3.94 mm wide typical, with a seated height under 2.44 mm. The tape-and-reel packaging (TR suffix) delivers 3000 units per reel on 13-inch reels, compatible with standard pick-and-place and reflow profiles per JEDEC J-STD-020. The moisture sensitivity level (MSL) is typically Level 1 for this package — no bake required before reflow if the shelf life is unexpired.
Sourcing and lifecycle posture
The power line protection flag is set to 'No' — this device is intended for DC rail or signal-line clamping, not for AC mains surge suppression. It does not carry UL 1449 or IEC 61643-11 certification for primary AC service entrance protection. Sourced through independent and authorized distribution channels.
