PESD30VF1BLYL

PESD30VF1BLYL is a single-channel transient-voltage-suppressor (ESD protection diode) from Nexperia’s PESD family. It protects a single I/O line from electrostatic discharges by clamping fast transients to safe levels. It has a 30 V stand-off voltage, making it suitable for lines that can swing up to about 30 V while preserving signal integrity with very low capacitance. The device is intended to be placed between the protected line and system ground, near connectors or entry points, to divert ESD away from sensitive ICs. It provides fast response (nanosecond-scale) and low leakage. The part is offered in a compact surface-mount package appropriate for mobile and embedded boards. For exact specs—capacitance, leakage, clamp voltage, package type, and pinout—consult the datasheet and follow recommended PCB layout to maximize ESD protection.

PESD30VF1BLYL features (concise):
- Single-line ESD protection diode (TVS) with 30 V working voltage (VRWM)
- Ultra-low capacitance suitable for high-speed interfaces (sub-pF range)
- Very fast response to ESD events; clamps to protect downstream ICs
- Low leakage in normal operation
- Robust protection against ESD surges (HBM/IEC stress levels per datasheet)
- Small, lead-free, RoHS-compliant package (LYL)
- Compact footprint suitable for portable/high-density designs
Note: for exact electrical specs (clamp voltage, leakage, test standards), please refer to the official datasheet.

- Pin count: 3 pins (SOT-23-3 package).
- Function: 1-channel unidirectional TVS diode for ESD protection of a single I/O line; clamps transient voltages to ground, protecting the protected circuitry (30 V stand-off voltage as indicated by the part number).

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (headquartered in the Netherlands) that specializes in high-volume discrete semiconductors, MOSFETs, logic and analog ICs and protection devices (including TVS/ESD diodes like the PESD30VF1BLYL).

PESD30VF1BLYL is a unidirectional ESD protection diode for a single I/O line with a 30 V working voltage. It shields sensitive IC inputs from ESD surges on external connectors while preserving signal integrity on high-speed lines (low capacitance, fast clamp).
Typical application areas:
- Protection for USB, HDMI, MIPI-CSI/DSI, LVDS interface lines
- Camera sensors, display panels, microcontroller I/O
- Memory card interfaces, audio jacks, and other external connectors
- Used in portable consumer devices and in automotive/industrial electronics with exposed I/O lines.
