This is the voltage the TVS forces across the protected line during the surge — any IC rated for at least 24.4 V absolute maximum on its supply pin survives the event. The breakdown voltage (V_BR) is 16.7 V minimum, meaning the diode starts avalanche conduction between 16.7 V and the clamping ceiling. For shorter pulses (8/20 µs), the device can handle significantly higher peak current — the datasheet derating curve shows the power capability increases as pulse width decreases. ## DO-214AA SMB package — board integration and temperature range Housed in the DO-214AA (SMB) surface-mount package, the SMBJ15A-13 occupies a standard footprint for 600 W class TVS diodes. The operating junction temperature range spans -55 °C to +150 °C, covering the full industrial temperature envelope and extending into automotive under-hood zones. The wide TJ range means the TVS maintains its clamping characteristics across cold-start and hot-soak conditions without derating. ## Active production — current lifecycle for BOM stability The base product number is SMBJ15, covering the entire 15 V variant family across package options and channel configurations. The '-13' suffix denotes the tape-and-reel packaging format for automated pick-and-place assembly.","metaTitle":"SMBJ15A-13 TVS Diode, 600W, 15V Standoff, DO-214AA","metaDescription":"SMBJ15A-13 unidirectional TVS diode, 600W peak pulse power, 15V reverse standoff, 24.4V clamp at 24A.
