Product details
Overview
PESD1IVN27L-Q from Nexperia is a bidirectional ESD protection diode in DFN1006-2 (SOD882) package, designed for automotive in-vehicle network bus lines. It delivers 27 V reverse stand-off voltage, 36 V clamping at 3 A, 30 kV IEC 61000-4-2 ESD immunity, 1 nA leakage, and 14–17 pF capacitance - enabling robust transient suppression on CAN, LIN, FlexRay, and SENT interfaces.
For engineers reviewing the PESD1IVN27L-Q datasheet, PESD1IVN27L-Q pinout, PESD1IVN27L-Q application, or PESD1IVN27L-Q equivalent, this device supports high-reliability automotive signal line protection where low capacitance, fast response, AEC-Q101 qualification, and ultra-small footprint are critical selection criteria.
Technical Context
This dual-cathode bidirectional TVS diode uses a symmetrical silicon avalanche structure to clamp both positive and negative transients without polarity dependence. Its 14–17 pF capacitance at 0 V ensures minimal signal distortion on high-speed IVN buses up to 1 Mbps (LIN) and 5 Mbps (CAN FD).
The device operates with a dynamic resistance of 0.3 Ω under 10 ns TLP pulses, enabling rapid energy diversion away from sensitive transceivers. Junction temperature rating up to 150 °C and storage range from −65 °C to +150 °C support under-hood deployment in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 27 V - Ensures stable operation below bus operating voltage without leakage-induced signal degradation |
| Clamping Voltage | 36 V at 3 A (8/20 µs) - Limits transient voltage seen by downstream transceiver to safe level during surge events |
| ESD Withstand | 30 kV per IEC 61000-4-2 contact discharge - Meets automotive OEM ESD immunity requirements for connector-level stress |
| Capacitance | 14–17 pF at 1 MHz, 0 V - Preserves signal integrity on LIN/CAN lines without added timing skew or attenuation |
| Leakage Current | 1 nA at 27 V - Prevents DC loading or battery drain in always-on vehicle networks |
| Package | DFN1006-2 (SOD882), 1.0 × 0.6 × 0.48 mm - Enables placement directly at board edge connectors with minimal PCB area |
Pinout & Package
DFN1006-2 (SOD882) is a leadless, ultra-small surface-mount plastic package with 2 terminals, 0.65 mm pitch, and dimensions of 1.0 mm × 0.6 mm × 0.48 mm. The marking bar indicates cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides low-impedance path to ground for positive transients on protected line |
| 2 | Cathode (Diode 2) | Provides low-impedance path to ground for negative transients - enables bidirectional clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Symmetrical 27 V standoff and sub-36 V clamping for ± transients - eliminates need for external polarity management |
| AEC-Q101 qualification | Qualified per Automotive Electronics Council stress test standard - validated for under-hood thermal cycling and humidity exposure |
| Ultra-low capacitance | 14–17 pF at 0 V - maintains signal rise/fall times on 1–5 Mbps IVN buses without reflection or jitter |
| Low dynamic resistance | 0.3 Ω measured via TLP at 100 ns pulse - ensures fast energy shunting before transceiver damage threshold is exceeded |
| Minimal leakage | 1 nA max at rated VRWM - avoids cumulative current draw across multiple nodes in battery-sensitive systems |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed Controller Area Network (CAN) physical layer against ESD events at vehicle harness connectors. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between CAN_H/CAN_L differential pair and ground. Use Value: Clamps 30 kV contact ESD pulses to ≤36 V while adding only 14–17 pF loading - preserves CAN FD timing margins and common-mode noise rejection. |
Use Scenario: Safeguarding Local Interconnect Network (LIN) slave node transceivers from ESD during service port access or module replacement. IC Role / Device Role / Timing Role: Low-capacitance, bidirectional clamp on single-wire LIN bus line referenced to chassis ground. Use Value: Maintains LIN's 19.2 kbps signaling integrity with <1 nA leakage - prevents false wake-up or communication timeout in sleep-mode operation. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Shielding FlexRay communication channels in powertrain control units from electrostatic discharge during assembly or field maintenance. IC Role / Device Role / Timing Role: Dual-cathode TVS placed at FlexRay connector entry point to suppress ± transients on both channel wires. Use Value: Sub-36 V clamping at 3 A peak pulse ensures transceiver ICs remain within absolute maximum ratings during 8/20 µs surge events. |
Use Scenario: Securing Single Edge Nibble Transmission (SENT) sensor outputs in engine bay modules exposed to repeated ESD during diagnostic probing. IC Role / Device Role / Timing Role: Signal-line ESD clamp on SENT data line between pressure/temperature sensor and microcontroller input. Use Value: 1 nA leakage prevents DC offset accumulation on SENT's precise pulse-width encoded signals - avoids misinterpretation of nibble values. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC27A | Unidirectional, 27 V VRWM, 300 W peak power, DO-214AB package (4.5 × 3.5 mm) | Requires two devices for bidirectional protection; larger footprint limits routing near connectors | Select when higher surge rating (300 W vs. 100 W) is prioritized over size and bidirectionality |
| Vishay ESDBLE27-2 | Bidirectional, 27 V VRWM, 30 kV ESD, 15 pF, SOD-882 package - identical form factor and key specs | Same mechanical and electrical fit; minor parametric variation in VCL (37 V typ. vs. 36 V) | Drop-in alternative with identical layout compatibility and AEC-Q101 qualification for second-source assurance |
Compared with SZ1.5SMC27A, PESD1IVN27L-Q offers true bidirectional protection in half the PCB area; versus ESDBLE27-2, it provides tighter clamping (36 V vs. 37 V) and lower leakage (1 nA vs. 5 nA), enhancing reliability in low-power IVN nodes.

FAQ
Is PESD1IVN27L-Q qualified for automotive use?
Yes. PESD1IVN27L-Q is fully qualified to AEC-Q101 standards for discrete semiconductors, including temperature cycling, humidity testing, and ESD robustness validation. It is recommended for automotive in-vehicle network applications including CAN, LIN, FlexRay, and SENT, with operational junction temperature up to 150 °C.
What is the significance of the dual-cathode pinning?
The dual-cathode configuration (Pin 1 = K1, Pin 2 = K2) enables intrinsic bidirectional clamping: each cathode connects to ground, allowing the internal diodes to conduct during both positive and negative transients on the protected line. This eliminates external polarity constraints and simplifies PCB layout versus unidirectional alternatives.
How does its 14–17 pF capacitance affect CAN or LIN signal integrity?
At 14–17 pF, PESD1IVN27L-Q introduces negligible capacitive loading on CAN (up to 1 Mbps) and LIN (19.2 kbps) buses. Measured rise/fall time degradation remains below 5% - well within specification margins - ensuring reliable bit error rate performance and avoiding signal reflection or timing violations.
Can PESD1IVN27L-Q replace older Nexperia PESD1CAN series parts?
No direct drop-in replacement exists: PESD1CAN parts target 12 V CAN systems with 12–15 V VRWM, whereas PESD1IVN27L-Q is optimized for 27 V IVN lines like LIN and SENT. Substituting requires verifying bus voltage margin, clamping headroom, and ESD test compliance - not a generic upgrade.
