Key Features
- AEC-Q101 automotive qualification ensures reliable ESD protection in harsh vehicle environments up to 125°C
- Ultra-low 15 V clamping voltage with 2.5 A (8/20 µs) peak pulse capability shields sensitive 5 V and 3.3 V interfaces
- Tiny 2-pin X1SON package (1 mm × 0.6 mm) minimizes board area for space-constrained automotive and consumer designs
Applications
The TPD1E01B04DPYRQ1 is designed to protect automotive CAN bus, LIN, and sensor interface lines from electrostatic discharge and electrical fast transients. Its AEC-Q101 qualification and -40°C to 125°C operating range make it suitable for under-hood electronic control units and body control modules. Consumer and industrial designers also use it to guard USB, HDMI, and GPIO pins on microcontrollers against ESD events exceeding IEC 61000-4-2 Level 4 requirements.

Frequently Asked Questions
What peak pulse current can TPD1E01B04DPYRQ1 handle, and how does that relate to IEC 61000-4-5 surge testing?
The TPD1E01B04DPYRQ1 handles 2.5 A peak pulse current under the standard 8/20 µs surge waveform, which corresponds to the IEC 61000-4-5 test for conducted disturbances on signal lines. At that pulse level the clamping voltage stays at or below 15 V, protecting downstream ICs rated for 5 V operation.
Why would an automotive engineer choose TPD1E01B04DPYRQ1 over a general-purpose TVS for a CAN transceiver protection circuit?
The AEC-Q101 qualification of TPD1E01B04DPYRQ1 guarantees the device is screened for automotive reliability over the -40°C to 125°C temperature range required for under-hood environments. A general-purpose TVS lacks this qualification and may exhibit unacceptable leakage or parameter drift at the 125°C junction temperatures common in engine-bay ECUs.
How does the 6.4 V breakdown voltage of TPD1E01B04DPYRQ1 make it suitable for 5 V logic protection?
With a 6.4 V minimum breakdown voltage, the TPD1E01B04DPYRQ1 remains in reverse blocking mode during normal 5 V signal operation, adding only a few picofarads of capacitance to the line. Under an ESD strike the diode begins conducting above 6.4 V and clamps the transient to 15 V maximum, well within the absolute maximum ratings of most 5 V CMOS inputs.
What board footprint does the X1SON package of TPD1E01B04DPYRQ1 require, and how does that compare to SOD-523?
The 2-pin X1SON package of TPD1E01B04DPYRQ1 measures only 1.0 mm × 0.6 mm, occupying roughly 0.6 mm² of PCB area. A standard SOD-523 diode is about 1.6 mm × 0.8 mm (1.28 mm²), so the X1SON saves over 50% of board real estate in high-density automotive sensor modules.
