概述
Description
PESD12VL1BA is a single-line, ultra-low-capacitance ESD protection diode from the PESD family (Nexperia). It protects one data line from electrostatic discharge while adding minimal signal distortion for high-speed interfaces.
Key ideas:
- One-channel ESD protector with very low input capacitance (to preserve signal integrity on fast lines).
- Working voltage (VRWM) around 12 V; designed for data lines up to that range.
- Fast response, low leakage, suitable for protecting interfaces like USB, HDMI, MIPI, LCD data lines, etc.
- Available in a small package (suffix BA).
Regarding “,115”: that suffix isn’t a standard part code and may be a packaging, lot/date, or regional variant shown on a specific distributor or BOM. For exact electrical specs (HBM/CDM ratings, clamp voltages, capacitance) and package details, consult the official datasheet or distributor listing for your exact variant.
