The 78V reverse standoff voltage (VRWM) means the part conducts negligible leakage below that level — it sits across the rail without loading it. When a transient exceeds 86.7V (minimum breakdown), the Zener avalanche clamps the surge to 126V, shunting up to 4.7A peak pulse current to ground. ## Package and board-fit for field replacement The SMB body is large enough to hand-solder with tweezers and a fine tip, so a field swap on a populated board is practical without a reflow oven. The wide range also means the part survives soldering thermal shock without parametric shift. ## Active lifecycle and sourcing posture The base product number SMBJ78 covers both unidirectional and bidirectional variants — the CA suffix in SMBJ78CA-13-F specifically denotes the bidirectional channel.","metaTitle":"SMBJ78CA-13-F Diodes Inc TVS, 78V, 600W, DO-214AA","metaDescription":"SMBJ78CA-13-F bidirectional TVS diode, 78V reverse standoff, 600W peak pulse, DO-214AA SMB.
