AEC-Q101 TVS for 5V signal-line protection
The D5V0M1U2S9Q-7 is a unidirectional TVS diode from Diodes Incorporated, AEC-Q101 qualified for automotive applications. It clamps fast overvoltage transients on 5V signal lines used in HDMI, USB, and general automotive interfaces. Rated for a peak pulse power of 108W (8/20µs waveform) and a clamping voltage of 12V at 9A, it protects downstream ICs from ESD and surge events on data and control lines. The 54pF capacitance at 1MHz is low enough to preserve signal integrity on high-speed buses.
Voltage and temperature envelope
This window keeps the protected line below the abs-max of most 5V-tolerant ASICs and MCUs. Operating junction temperature spans -65°C to +150°C, matching the automotive underhood and powertrain thermal requirements.
Sourcing and compliance
As an AEC-Q101 qualified part, it ships with the standard Diodes Incorporated RoHS/REACH compliance documentation. The base product number D5V0M1 covers the family; the -7 suffix denotes the specific packaging variant.
