PESD12VL1BA,115

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.

Key features of PESD12VL1BA,115:
- 1-channel, low-capacitance ESD protection diode for a single data line
- Stand-off voltage: 12 V (unidirectional)
- Ultra-low capacitance: ~0.6 pF typ (preserves high-speed signal integrity)
- Very low leakage; fast response to ESD events
- Clamps ESD spikes to safe levels (typical clamping around ~20 V at 1 A)
- Wide operating temperature: -40°C to +125°C
- Small, RoHS-compliant, Pb-free surface-mount package
- Suitable for protecting interfaces such as USB, CAN, RS-485, HDMI, and other low-voltage/high-speed lines

Pin count: 3 pins (SOD523-style).
Pin functions:
- Pin 1: Protected I/O terminal (connected to pin 3 internally/pad pair)
- Pin 2: Ground (anode)
- Pin 3: Protected I/O terminal (same as pin 1)
Device function: single‑channel, unidirectional ESD/TVS protector for one data line to ground (low‑capacitance surge clamp for IEC 61000‑4‑2 ESD protection of high‑speed interfaces).

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (headquartered in Nijmegen, Netherlands) that designs and produces discrete components, logic ICs, MOSFETs and protection devices (including ESD diodes like the PESD series).
