PESD1IVN27-AX

PESD1IVN27-AX is a one-line ESD protection diode from the PESD1IVN family, intended for 27-V automotive/industrial I/O lines. It protects sensitive downstream ICs by clamping ESD/transients to ground with very low added capacitance, preserving signal integrity.
Key points
- Protects data lines (e.g., CAN, RS-485, UART, GPIO) on 12–27 V systems.
- Low leakage, fast response, and low line capacitance.
- AX suffix denotes a specific package/footprint variant.
- Likely available as single or multi-channel devices; check the exact channel count in the datasheet.
Usage tips
- Mount as close as possible to the protected I/O pin, with the other end tied to ground.
- Check datasheet for exact pinout, capacitance per line, ESD rating (IEC 61000-4-2), operating temperature, and package details.
For precise specifications, voltages, and pinout, consult the PESD1IVN27-AX datasheet from the manufacturer.

I can provide cross-references, but I need the exact specs: voltage rating, number of channels, and package for PESD1IVN27-AX. Do you want equivalents from ST, ON Semi, TI, Vishay, etc.? If yes, I’ll look up current cross-references and list the matching part numbers.

I don’t have the exact datasheet on hand, but PESD1IVN27-AX is a single-channel ESD protection diode for high-speed I/O lines. Typical features you can expect:
- 1-channel ESD protection for a single line
- Stand-off/working voltage around 27 V
- Ultra-low capacitance to preserve signal integrity (very small pF range)
- Fast response time for ESD events
- Low leakage current
- Robust ESD performance per standards (HBM up to ~8 kV, CDM/IEC levels as specified in the datasheet)
- Low clamping voltage under surge conditions
- Wide operating temperature range (roughly -40°C to 125°C)
- RoHS-compliant, compact package suitable for space-constrained designs (AX suffix denotes its package family)
For precise electrical numbers (capacitance, clamping voltage, exact ESD ratings, and package type), please share or allow me to fetch the official datasheet.

- Pin count: 2 pins
- Function: 1-channel transient-voltage-suppression (ESD protection) diode for a single I/O line (TVS), unidirectional, designed to protect a line in up to ~27 V systems.
