Product details
Overview
PESD1IVN27-LSYL from Nexperia is a bidirectional automotive-grade ESD protection diode in DFN1006BD-2 (SOD882BD) package, designed for transient suppression on in-vehicle network lines. It delivers 27 V reverse standoff voltage, 36 V clamping at 3 A, 30 kV IEC 61000-4-2/ISO 10605 ESD immunity, <1 nA leakage, and 14–17 pF capacitance - enabling robust CAN/LIN/FlexRay/SENT bus line protection in harsh automotive environments.
For engineers reviewing the PESD1IVN27-LSYL datasheet, PESD1IVN27-LSYL pinout, PESD1IVN27-LSYL application, or PESD1IVN27-LSYL equivalent, this page provides verified technical context, validated pin functions, automotive-specific design meaning of key specs, and confirmed alternatives for IVN bus protection layouts requiring AEC-Q101 qualification and side-wettable flanks for solder joint inspection.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure optimized for low-capacitance, high-speed data line protection. Its VBR of 28–38 V at 10 mA and dynamic resistance of 0.3 Ω ensure fast clamping response to ESD pulses while maintaining signal integrity on 1 Mbps+ automotive serial buses.
The DFN1006BD-2 package with side-wettable flanks supports automated optical inspection (AOI) of solder joints - critical for zero-defect automotive manufacturing. Thermal limits (Tj ≤ 150 °C, Tamb = −55 to +150 °C) and 3 A 8/20 μs peak pulse rating align with ISO 7637-2 surge and IEC 61000-4-5 compliance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Ensures no conduction during normal 24 V automotive bus operation with margin. |
| Clamping Voltage | 36 V (typ.) at 3 A - Limits transient voltage to safe levels for LIN/CAN transceivers rated ≤ 40 V. |
| ESD Rating | ±30 kV (IEC 61000-4-2 & ISO 10605) - Meets automotive OEM ESD test requirements for connector-level stress. |
| Diode Capacitance | 14–17 pF at 0 V - Minimizes signal distortion on high-speed SENT and FlexRay lines up to 10 Mbps. |
| Leakage Current | <1 nA at 27 V - Prevents measurable power loss in always-on vehicle networks. |
| Package | DFN1006BD-2 (SOD882BD), 1.0 × 0.6 × 0.47 mm - Enables ultra-compact placement adjacent to connectors with AOI-compatible side-wettable flanks. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless ultra-small surface-mount package with side-wettable flanks, 0.65 mm pitch, and dimensions of 1.0 mm × 0.6 mm × 0.47 mm. The marking bar indicates cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to protected line (e.g., LIN bus); forms one half of bidirectional clamping path. |
| 2 | Cathode (Diode 2) | Connects to ground; completes symmetrical ESD current path during positive/negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−55 °C to +150 °C) and reliability testing per stress test conditions. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder fillets - essential for zero-defect automotive PCB assembly. |
| Bidirectional clamping | Protects against both polarities of ESD without external biasing; matches differential signaling on CAN/FlexRay. |
| Low dynamic resistance | 0.3 Ω typical - reduces voltage overshoot during fast transients and improves energy handling consistency. |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface on 12 V CAN FD networks in body control modules. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point before CAN transceiver. Use Value: Clamps 30 kV contact discharge to ≤36 V within nanoseconds, preventing transceiver latch-up or permanent damage. | Use Scenario: Protection of LIN slave node (e.g., door module actuator) exposed to human touch in cabin environment. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp between LIN line and chassis ground, minimizing signal rise-time degradation. Use Value: 14–17 pF capacitance preserves LIN's 19.2 kbps timing budget while blocking >30 kV ESD events. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Transient suppression on FlexRay A/B channels in powertrain gateways operating up to 10 Mbps. IC Role / Device Role / Timing Role: High-speed ESD diode mounted within 2 mm of connector pins to reduce inductive loop area. Use Value: Sub-1 nA leakage avoids DC offset errors; 0.3 Ω Rdyn ensures consistent clamping across multiple ESD strikes. | Use Scenario: Protecting SENT output of engine knock sensor from ESD during service port access. IC Role / Device Role / Timing Role: Single-line unidirectional-capable clamp (used in dual-diode configuration) on SENT signal path to microcontroller. Use Value: 27 V VRWM accommodates SENT's 12 V supply rail; 36 V VCL prevents overvoltage on MCU input pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Quad-channel, 5 V VRWM, higher 30 pF capacitance, SO-8 package | Designed for multi-line protection (e.g., USB + UART + I²C), not optimized for single high-speed IVN line | Select when protecting multiple low-speed interfaces on same board; avoid for CAN/FlexRay due to capacitance and package size |
| Vishay VEML6040-GS08 | Not applicable - optical sensor, unrelated function | N/A | Excluded: misidentified part; no functional equivalence |
Compared with PESD1IVN27-LSYL, NUP4105MR6T1G offers multi-line integration but sacrifices bandwidth and board space efficiency; no valid alternative matches its combination of 27 V rating, 17 pF, AEC-Q101, and DFN1006BD-2 footprint for single-line IVN protection.

FAQ
What is the maximum junction temperature rating for PESD1IVN27-LSYL?
The absolute maximum junction temperature is 150 °C, per IEC 60134 limiting values. This enables reliable operation in under-hood environments where ambient temperatures reach 125 °C and power dissipation remains low due to sub-nA leakage and minimal clamping energy absorption during transient events.
Does PESD1IVN27-LSYL support automated optical inspection (AOI)?
Yes - its DFN1006BD-2 package features side-wettable flanks, allowing AOI systems to verify solder fillet formation on both lateral edges. This meets automotive zero-defect manufacturing requirements and eliminates need for X-ray inspection in standard SMT lines.
Can PESD1IVN27-LSYL be used on 48 V automotive systems?
No - its 27 V reverse standoff voltage and 28–38 V breakdown range make it unsuitable for 48 V architectures. For 48 V buses, Nexperia's PESD1IVN48-LS (48 V VRWM) or equivalent AEC-Q101 devices with ≥50 V VBR must be selected to maintain sufficient margin above system rail.
How does the dual-cathode configuration enable bidirectional protection?
The two cathodes (Pin 1 and Pin 2) form a back-to-back diode pair: during positive transients, current flows from Pin 1 to Pin 2; during negative transients, current flows from Pin 2 to Pin 1. This symmetric structure provides identical clamping behavior for both polarities without external biasing or polarity constraints.
