The 77.4 V maximum clamping voltage at the 7.7 A peak pulse current defines the voltage the downstream circuitry must survive during a surge. The 7.7 A peak pulse current is the current the diode shunts at the clamping voltage — a figure that scales with the surge waveform duration. The supplier device package is also SMB, confirming the same mechanical outline across Diodes Incorporated documentation. The junction temperature rating sets the derating curve for peak pulse power at elevated temperatures. The base product number is SMBJ48, which identifies the 48 V standoff variant within the SMBJ family.","metaTitle":"SMBJ48CA-13-F Diodes Inc TVS Diode, 48V, 600W, DO-214AA","metaDescription":"SMBJ48CA-13-F Zener TVS diode, 48V reverse standoff, 77.4V clamp, 600W peak pulse.
