A 5 V rail sees 1.4 V of headroom before the TVS begins to avalanche; the clamping voltage at 9.2 V then limits the peak stress that propagates downstream. This window is typical of a 5 V rail protector in automotive and telecom applications where the supply tolerance band is narrow and the transient duration is short. ## Junction temperature and surface-mount form factor Junction operating temperature is rated to 150 °C (TJ), with an absolute minimum of -55 °C. This span covers engine-compartment ambient swings without derating in most automotive module housings. Tape-and-reel packaging supports standard SMT assembly flow. No official Bourns successor order code is cross-referenced for this part. The 5.0SMDJ-Q series is a established family — when evaluating alternatives within the series, confirm that the standoff and peak pulse ratings match the application requirement before substituting.","metaTitle":"Bourns 5.0SMDJ5.0A-QH TVS Diode, 5kW Peak, 5V Standoff","metaDescription":"Bourns 5.0SMDJ5.0A-QH unidirectional TVS Zener, 5V standoff, 9.2V clamping, 5kW peak pulse, AEC-Q101, DO-214AB SMC.
