600W bidirectional Zener TVS in a DO-214AA SMB package
The SMBJ110CA-13: Packaged in a standard DO-214AA (SMB) surface-mount package, it is intended for general-purpose overvoltage protection on a 110V rail — the standoff voltage is the maximum DC or AC peak the protected line can carry without the TVS conducting appreciably.
Voltage ratings and what they mean for rail protection
The 110V reverse standoff (V_RWM) is the working voltage: a 110V DC bus or 110VAC peak (about 78V RMS) can ride on this line without the diode leaking beyond spec. The breakdown voltage (V_BR) is 122V minimum — that is where the device starts to avalanche. The 600W peak pulse rating means it can absorb a 3.4A, 10/1000µs surge without failing; for shorter pulses (8/20µs) the peak power capability is higher, though the datasheet's pulse-derating curve governs the actual limit.
Temperature range and package for field service
The DO-214AA SMB package is a standard two-lead footprint; on a rework bench or in a field kit, it swaps with a conventional soldering iron and tweezers, no hot-air station required. Power line protection is marked 'No' — this is a signal- or low-power-rail TVS, not a primary mains suppressor.
Active production and sourcing posture
Diodes Incorporated lists the SMBJ110CA-13 as Active (current production). The base product number is SMBJ110, so the -13 suffix denotes the reel packaging variant — the bare die and electrical specs are identical across the SMBJ110 family.
