Product details
Overview
PESD1LIN,135 from Nexperia is a dual-cathode asymmetrical ESD protection diode in SOD323 (SC-76) package, designed specifically for single-line automotive LIN bus protection. It delivers 23 kV IEC 61000-4-2 contact ESD immunity, 160 W peak pulse power (8/20 µs), and clamps to 40 V at 1 A surge current-enabling robust transient suppression in LIN transceiver interfaces of body control modules and door ECUs.
For engineers reviewing the PESD1LIN,135 datasheet, PESD1LIN,135 pinout, PESD1LIN,135 application, or PESD1LIN,135 equivalent, key selection criteria include reverse standoff voltage (15 V or 24 V variant), ultra-low leakage (<1 nA), 13–17 pF capacitance, AEC-Q101 qualification, and dual-cathode configuration for optimized EMI suppression on bidirectional LIN signal lines.
Technical Context
The PESD1LIN,135 implements an asymmetrical dual-diode architecture with separate cathodes (Pin 1 for 15 V variant, Pin 2 for 24 V variant), enabling independent optimization of forward conduction and reverse clamping for LIN bus polarity tolerance. Its low differential resistance (≤300 Ω) and fast response ensure sub-100 ns clamping during ESD events.
It meets IEC 61000-4-2 Level 4 (±23 kV contact), IEC 61000-4-5 surge (3 A, 8/20 µs), and MIL-STD-883 HBM (10 kV), with junction temperature rated to 150 °C-making it suitable for under-hood and cabin-mounted automotive electronics operating across −65 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V or 24 V - defines maximum continuous line voltage before leakage rise; selects variant per LIN system supply (12 V or 24 V nominal) |
| Clamping Voltage | 40 V at 1 A (24 V variant) - ensures LIN transceiver I/O remains below absolute max rating during surge |
| Peak Pulse Power | 160 W (8/20 µs) - sustains high-energy transients without thermal failure in automotive load-dump or coupling scenarios |
| Diode Capacitance | 13–17 pF at 0 V, 1 MHz - preserves LIN signal integrity (20.2 kbaud) with minimal edge distortion or timing jitter |
| ESD Withstand | 23 kV contact discharge (IEC 61000-4-2) - exceeds automotive OEM requirements for connector-level ESD robustness |
| Leakage Current | <1 nA at VRWM - prevents DC loading of LIN bias networks and avoids false wake-up in sleep-mode ECUs |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - validates reliability for automotive production use |
Pinout & Package
Package: SOD323 (SC-76), surface-mount plastic package with 2 leads, 0.95 mm pitch, footprint per Nexperia ref. sod323_fr; dimensions 2.7 × 1.6 × 1.1 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (15 V variant) | Connected to LIN bus line when using 15 V-rated version; provides low-impedance path to ground during positive transients |
| 2 | Cathode (24 V variant) | Connected to LIN bus line when using 24 V-rated version; enables same footprint support for dual-system voltage architectures |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical dual-cathode topology | Enables independent optimization of clamping for positive/negative LIN transients while sharing one anode to GND |
| Ultra-low capacitance (13–17 pF) | Maintains LIN signal rise/fall time compliance (<1 µs) without degrading bus timing margins or causing bit errors |
| Sub-1 nA reverse leakage | Eliminates parasitic current draw on LIN pull-up resistors, preserving sleep current budget in battery-sensitive nodes |
| 160 W peak pulse power handling | Withstands coupled surges from adjacent 12 V/24 V power domains without degradation over lifetime |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity, mechanical shock, and long-term reliability per industry standard |

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 | Unidirectional, single-cathode, 6.1 V VRWM, higher capacitance (35 pF) | Designed for generic low-voltage data lines-not optimized for LIN's 12/24 V swing or bidirectional signaling | Select only if system uses external voltage translation or operates below 8 V; not recommended for direct LIN bus placement. |
| TPD2E001DRYR | Two-channel unidirectional, 5.5 V VRWM, 12 pF, no AEC-Q101 qualification | Targeted at consumer USB/IO protection; lacks automotive surge rating and temperature range validation | Acceptable for non-automotive LIN prototypes; unsuitable for production vehicles due to missing AEC-Q101 and IEC 61000-4-5 compliance. |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, PESD1LIN,135 uniquely combines dual-voltage standoff selection (15 V/24 V), asymmetrical clamping, AEC-Q101 qualification, and LIN-specific capacitance-making it the only drop-in solution validated for production automotive LIN nodes.

FAQ
What is the difference between the PESD1LIN (15 V) and (24 V) variants?
The PESD1LIN,135 corresponds to the 24 V variant, with reverse standoff voltage of 24 V and breakdown voltage of 25.4–30.3 V at 5 mA. The 15 V variant has VRWM = 15 V and VBR = 17.1–20.3 V. Both share identical SOD323 package and pinout but differ in internal doping and junction design to match respective LIN system supply rails.
Can PESD1LIN,135 be used on a 5 V LIN-like bus?
No-PESD1LIN,135 is not recommended for 5 V buses. Its 24 V VRWM causes excessive leakage and poor clamping margin below 12 V operation. For sub-12 V interfaces, Nexperia's PESD1CAN series or ESDALC6V1-1U2 are better matched, though neither supports LIN's bidirectional transient profile.
How does the asymmetrical cathode configuration improve EMI suppression?
The dual-cathode layout allows independent tuning of forward and reverse conduction paths: Pin 1 handles positive transients (anode-to-Pin1), Pin 2 handles negative transients (anode-to-Pin2). This reduces common-mode noise injection into ground and improves radiated emissions performance in LIN ECUs by >6 dB compared to symmetrical diodes.
Is PESD1LIN,135 compatible with lead-free reflow soldering profiles?
Yes-PESD1LIN,135 is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Its SOD323 package uses matte tin termination and withstands three reflow cycles. Recommended footprint matches Nexperia's sod323_fr drawing: 0.95 mm pad length, 0.6 mm width, 0.5 mm solder mask clearance.
