Product details
Overview
PESD2IVN27T-Q from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed for bidirectional transient suppression on two in-vehicle network lines. It features 27 V reverse standoff voltage, 36 V clamping voltage at 3 A, 13–17 pF diode capacitance, 0.1% capacitance matching, and AEC-Q101 qualification - enabling robust CAN, LIN, FlexRay, and SENT bus line protection.
For engineers reviewing the PESD2IVN27T-Q datasheet, PESD2IVN27T-Q pinout, PESD2IVN27T-Q application, or PESD2IVN27T-Q equivalent, key selection criteria include clamping performance under 8/20 µs surge, ultra-low leakage (<1 nA), matched capacitance for differential signal integrity, and ISO 10605/IEC 61000-4-2 30 kV ESD rating in automotive environments.
Technical Context
This device implements a common-cathode dual-diode architecture with pins 1 (K1) and 2 (K2) serving as independent cathodes for two protected lines, and pin 3 (CC) as the shared cathode return path. Its symmetrical V-I characteristics support bidirectional ESD clamping across both channels without polarity constraints.
It delivers low dynamic resistance (0.25 Ω) and tight capacitance matching (∆Cd/Cd = 0.1%) to preserve signal fidelity on high-speed automotive buses. The 27 V VRWM ensures compatibility with 24 V system rails while maintaining margin against transients per ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Blocks normal bus operation voltages up to 27 V while remaining non-conductive. |
| Clamping Voltage | 36 V at 3 A (8/20 µs) - Limits transient voltage seen by downstream transceivers during surge events. |
| ESD Rating | ±30 kV (IEC 61000-4-2 & ISO 10605) - Withstands contact discharge up to automotive-grade ESD stress levels. |
| Diode Capacitance | 13–17 pF at 1 MHz, 0 V - Minimizes signal distortion on CAN/FlexRay buses operating up to 5 Mbps. |
| Capacitance Matching | 0.1% ∆Cd/Cd - Ensures balanced loading on differential pairs, preserving common-mode rejection. |
| Leakage Current | <1 nA at 27 V - Prevents DC loading or battery drain in always-on vehicle networks. |
| Peak Pulse Current | 3 A (8/20 µs) - Handles repetitive surge energy per ISO 7637-3 without degradation. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body. RoHS-compliant, AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected IVN line (e.g., CANH); forms clamping path to CC during positive transients. |
| 2 | K2 (cathode of diode 2) | Connects to second protected IVN line (e.g., CANL); enables independent but matched protection per channel. |
| 3 | CC (common cathode) | Shared return path to ground or chassis; enables compact dual-line layout with single-point transient sink. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Clamps ±30 kV ESD pulses symmetrically on both channels without external biasing. |
| Matched Capacitance | 0.1% inter-channel capacitance deviation preserves differential signal timing and impedance balance. |
| Low-Leakage Protection | <1 nA reverse current avoids loading on low-power IVN nodes like LIN slave devices. |
| Automotive Qualification | AEC-Q101 qualified for junction temperatures up to 150 °C and storage down to −65 °C. |
| Surge Robustness | Withstands ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) without parametric shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUF2221MUTAG | 24 V VRWM, 33 V clamping at 3 A, 15 pF typical, no capacitance matching spec | Lower standoff voltage limits use in 24 V systems with tighter margins; lacks ∆Cd/Cd guarantee | Select when cost sensitivity outweighs need for matched capacitance on differential buses. |
| Vishay VEML6040X01 | 27 V VRWM, 40 V clamping at 3 A, 12 pF, AEC-Q101, but single-channel configuration | Requires two devices for dual-line protection, increasing PCB area and BOM count | Choose only if discrete placement flexibility is prioritized over space-constrained SOT23 integration. |
Compared with NUF2221MUTAG and VEML6040X01, PESD2IVN27T-Q uniquely combines matched capacitance, common-cathode dual-channel integration, and 36 V clamping in one SOT23 footprint - optimizing board space, signal balance, and surge margin for modern IVN architectures.

FAQ
What is the maximum operating temperature for PESD2IVN27T-Q?
The device supports continuous operation up to +150 °C junction temperature and ambient temperatures from −55 °C to +150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. This range covers under-hood ECU environments and powertrain module placements without derating.
Can PESD2IVN27T-Q protect both CANH and CANL simultaneously?
Yes - pins 1 and 2 connect independently to CANH and CANL, while pin 3 (CC) serves as the common cathode return. This configuration provides matched, bidirectional clamping on both lines with identical electrical behavior, preserving CAN differential signaling integrity.
Does PESD2IVN27T-Q require external biasing or series resistors?
No - it operates passively as a voltage-triggered clamp with no external components needed. Its 27 V VRWM ensures non-conduction during normal CAN/LIN bus operation (typically ≤12 V or 24 V), and its low leakage (<1 nA) eliminates need for pull-up/down resistors.
How does the 0.1% capacitance matching benefit differential bus performance?
This matching minimizes inter-channel capacitance skew, reducing differential-to-common-mode conversion and maintaining >30 dB common-mode rejection ratio (CMRR) on CAN/FlexRay buses. It prevents timing skew that could cause bit errors at data rates up to 10 Mbps.
