Product details
Overview
PESD1LIN from Nexperia is a dual-cathode automotive-grade ESD protection diode in SOD323 (SC-76) package, designed specifically to protect a single LIN bus line against IEC 61000-4-2 ESD (up to 23 kV contact), IEC 61000-4-5 surge (3 A, 8/20 µs), and EMI-induced transients in vehicle ECUs. It features asymmetrical configuration, 15 V or 24 V reverse standoff voltage options, <1 nA leakage, and clamping voltage of 25 V (1 A) for 15 V variant and 40 V (1 A) for 24 V variant.
For engineers reviewing the PESD1LIN datasheet, PESD1LIN pinout, PESD1LIN application, or PESD1LIN equivalent, this device is selected for LIN physical layer transient suppression where low capacitance (13–17 pF), AEC-Q101 qualification, and precise clamping behavior under fast-rising ESD pulses are critical design requirements.
Technical Context
The PESD1LIN implements an asymmetrical dual-diode topology with separate cathodes for 15 V and 24 V variants-enabling optimized EMI filtering and differential transient suppression on LIN signal lines. Its breakdown voltage is 18.9 V (typ.) for the 15 V version and 27.8 V (typ.) for the 24 V version, ensuring robust margin above nominal LIN bus voltages (12 V or 24 V systems).
It delivers 160 W peak pulse power at 8/20 µs waveform while maintaining ultra-low junction capacitance (13–17 pF @ 1 MHz) and differential resistance ≤225 Ω (15 V) or ≤300 Ω (24 V), preserving signal integrity on low-speed (20.2 kbps) LIN communication without distortion or timing skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V or 24 V - defines maximum continuous operating voltage before conduction; matches LIN bus nominal levels in 12 V or 24 V automotive architectures. |
| Clamping Voltage | 25 V @ 1 A (15 V variant); 40 V @ 1 A (24 V variant) - limits transient overvoltage seen by downstream LIN transceiver during ESD events. |
| Peak Pulse Power | 160 W @ 8/20 µs - sustains high-energy surges per IEC 61000-4-5 without failure, enabling single-device protection for LIN node-level compliance. |
| Diode Capacitance | 13–17 pF @ 0 V, 1 MHz - minimizes signal loading on LIN bus, avoiding rise/fall time degradation or reflection issues in daisy-chained networks. |
| ESD Withstand | 23 kV contact discharge per IEC 61000-4-2 Level 4 - exceeds automotive OEM requirements for human-body ESD immunity at connector interfaces. |
| Leakage Current | <1 nA @ VRWM - prevents DC loading on LIN bias network, preserving wake-up sensitivity and low-power sleep mode operation. |
| AEC-Q101 Qualified | Qualified for automotive discrete semiconductors - ensures reliability across −65 °C to +150 °C junction temperature range in engine bay and cabin modules. |
Pinout & Package
Supplied in SOD323 (SC-76) surface-mount plastic package: 2.3 mm × 1.35 mm × 0.95 mm body, 0.95 mm lead pitch, gull-wing terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (15 V variant) | Anode tied to LIN bus line; cathode connects to ground - forms unidirectional clamp for positive transients in 12 V system designs. |
| 2 | Cathode (24 V variant) | Anode tied to LIN bus line; cathode connects to ground - provides higher-voltage clamping for 24 V commercial vehicle applications. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical dual-diode configuration | Enables optimized EMI filtering and directional transient suppression on LIN bus, reducing common-mode noise coupling into ECU ground planes. |
| Ultra-low leakage current | <1 nA ensures no measurable impact on LIN bus pull-up/pull-down resistors, preserving wake-up detection and low-power idle current budgets. |
| Low clamping voltage at 1 A | 25 V (15 V variant) / 40 V (24 V variant) protects LIN transceivers rated for ≤40 V absolute maximum, preventing latch-up or oxide damage. |
| 13–17 pF capacitance | Maintains LIN signal edge integrity up to 20.2 kbps without overshoot or ringing, supporting reliable multi-node arbitration and error detection. |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin environments, including thermal cycling, humidity, and mechanical shock per AEC stress test plan. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN-bus ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1U2 | Single-line 6.1 V clamping diode; lower VRWM (6.1 V), higher Cd (30 pF); not AEC-Q101 qualified. | Targeted at non-automotive industrial LIN nodes; unsuitable for 12 V/24 V bus voltage margins. | Select only for cost-sensitive non-automotive LIN gateways where bus voltage remains below 7 V. |
| TPD1E05U06DPYR | Single-channel 5.5 V clamping; 0.5 pF Cd; AEC-Q101 qualified but rated for 12 kV ESD (IEC 61000-4-2), not 23 kV. | Used in infotainment LIN sub-nodes; lacks surge rating (no IEC 61000-4-5 compliance). | Choose when ultra-low capacitance is prioritized over surge immunity, e.g., LIN-to-MCU debug interfaces. |
Compared with ESDALC6V1-1U2 and TPD1E05U06DPYR, PESD1LIN uniquely combines AEC-Q101 qualification, 23 kV ESD rating, 3 A surge capability, and dual-voltage option-all within the same SOD323 footprint-making it the only drop-in solution for production automotive LIN ECU front-end protection.

FAQ
What is the difference between PESD1LIN (15 V) and PESD1LIN (24 V) variants?
The PESD1LIN is offered in two voltage grades: the 15 V variant has VRWM = 15 V and VBR = 17.1–20.3 V, intended for 12 V automotive systems; the 24 V variant has VRWM = 24 V and VBR = 25.4–30.3 V, designed for 24 V commercial vehicle applications. Both share identical SOD323 package, pinout, and AEC-Q101 qualification.
Can PESD1LIN protect against both ESD and surge events?
Yes-PESD1LIN is certified to IEC 61000-4-2 Level 4 (23 kV contact discharge) and IEC 61000-4-5 (3 A, 8/20 µs surge), delivering 160 W peak pulse power. Its clamping performance is characterized at both 1 A and 3 A, enabling single-device protection against both fast ESD transients and slower surge waveforms on LIN bus lines.
How should PESD1LIN be placed on the PCB for optimal protection?
Per Nexperia application guidance, PESD1LIN must be placed within 2 mm of the LIN connector, with minimal trace length between its anode and the protected line, and shortest possible ground return path to the local ground plane. Avoid shared ground paths and parallel routing with unprotected signals to prevent coupling.
Is PESD1LIN compatible with automated optical inspection (AOI) after reflow?
Yes-the SOD323 package features gull-wing leads with defined solder land patterns (0.6 mm × 0.5 mm per pad) and 0.95 mm pitch, fully compatible with standard AOI systems. The marking "AM" is laser-etched and legible under 20× magnification, supporting traceability and defect detection in high-volume automotive manufacturing.
