Product details
Overview
PESD2IVN24T-Q from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed to safeguard two in-vehicle network (IVN) bus lines-specifically CAN, LIN, FlexRay, and SENT-from ±30 kV IEC 61000-4-2 and ISO 10605 transients, with 24 V reverse standoff voltage, 33 V clamping at 3.5 A, and 14–17 pF typical diode capacitance per channel.
For engineers reviewing the PESD2IVN24T-Q datasheet, PESD2IVN24T-Q pinout, PESD2IVN24T-Q application, or PESD2IVN24T-Q equivalent, key selection criteria include bidirectional clamping performance, matched capacitance (<0.1% ΔCd/Cd), ultra-low leakage (1 nA), AEC-Q101 qualification, and common-cathode SOT23 layout for compact IVN interface protection.
Technical Context
This device implements a dual-channel, common-cathode TVS diode architecture optimized for high-speed automotive serial buses. Each channel provides symmetrical bidirectional clamping with breakdown voltage of 25.5–35.5 V and dynamic resistance of 0.2 Ω, enabling fast response to ESD pulses (tr < 1 ns) while maintaining signal integrity on differential pairs.
It meets ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) surge immunity requirements and supports operation across −55 °C to +150 °C ambient, with junction temperature rated up to 150 °C. The matched capacitance ensures minimal skew between protected lines-critical for timing-sensitive protocols like SENT and FlexRay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before conduction; sets upper limit for bus line DC bias compatibility (e.g., 24 V CAN FD or 12 V LIN). |
| Clamping Voltage | 33 V (typ.) at 3.5 A - Peak voltage seen by protected IC during 8/20 µs surge; ensures downstream transceivers remain below absolute maximum ratings. |
| ESD Rating | ±30 kV (IEC 61000-4-2 & ISO 10605) - Full system-level ESD robustness without external spark gaps or RC filters. |
| Diode Capacitance | 14–17 pF @ 1 MHz, 0 V - Low, balanced capacitance preserves signal rise/fall times on high-speed IVN lines (e.g., >2 Mbps CAN FD). |
| Capacitance Matching | ΔCd/Cd = 0.1 % - Ensures <0.1% inter-channel capacitance mismatch, minimizing differential skew and common-mode noise injection. |
| Leakage Current | 1 nA (typ.) @ 24 V - Negligible DC loading on bus lines; avoids false wake-up or voltage droop in low-power sleep modes. |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Confirms reliability for under-hood and infotainment module deployment. |
Pinout & Package
SOT23 plastic surface-mounted package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; optimized for automated placement and reflow soldering on dense automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected IVN line (e.g., CANH); forms anode-to-cathode path for negative transients on Channel 1. |
| 2 | K2 (Cathode 2) | Connects to second protected IVN line (e.g., CANL); enables independent clamping per line with shared cathode reference. |
| 3 | K (Common Cathode) | Ground return path for both channels; must be routed to low-inductance chassis or power ground to minimize clamping overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode topology | Enables compact, symmetric protection of differential bus pairs (e.g., CANH/CANL) using single-component footprint and shared ground path. |
| Ultra-low capacitance matching | 0.1% ΔCd/Cd ensures sub-picosecond timing skew between channels-essential for SENT pulse-width modulation accuracy and FlexRay bit timing. |
| Low clamping with high current handling | 33 V clamping at 3.5 A (8/20 µs) delivers 115 W peak pulse power while limiting voltage stress on 3.3 V/5 V transceiver I/O pins. |
| AEC-Q101 qualified & automotive-graded | Validated for −55 °C to +150 °C operation and 1000-cycle temperature cycling-meets requirements for engine control, ADAS, and body electronics modules. |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: ESD protection at OBD-II connector or gateway ECU interface where CANH/CANL lines are exposed to service personnel handling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, shunting ESD energy to chassis ground before reaching CAN transceiver. Use Value: Prevents latch-up or permanent damage to TJA1042/TJA1057 transceivers during 8 kV contact discharge events-verified per ISO 10605 test setup. | Use Scenario: Protecting LIN slave nodes (e.g., door modules, sensors) connected via long harnesses susceptible to cable-borne ESD coupling. IC Role / Device Role / Timing Role: Low-capacitance clamp on LIN bus line (single-wire, 12 V biased), preserving 19.2 kbps signaling integrity during transient events. Use Value: Maintains <1% signal distortion at 19.2 kbps due to 14–17 pF capacitance and <0.1% channel mismatch-enabling reliable frame synchronization. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: High-reliability protection of FlexRay A/B channels in x-by-wire systems (e.g., steer-by-wire ECUs) where deterministic timing is safety-critical. IC Role / Device Role / Timing Role: Dual-channel clamp ensuring matched propagation delay and voltage limiting on both differential pairs to avoid skew-induced protocol errors. Use Value: 0.1% capacitance matching limits inter-pair skew to <10 ps-within FlexRay's 50 ps jitter budget for 10 Mbps data rates. | Use Scenario: Protecting SENT output lines from pressure/temperature sensors in powertrain applications where ESD may occur during sensor replacement or harness mating. IC Role / Device Role / Timing Role: Clamp on SENT signal line (0–5 V swing, 125 kHz carrier) with minimal capacitive loading to preserve pulse-width resolution. Use Value: 14–17 pF capacitance introduces <0.5% duty cycle error at 125 kHz-maintaining <1% total measurement error for 12-bit sensor resolution. |
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 NUP2114 | Higher clamping voltage (40 V at 3.5 A); 22 pF capacitance; no capacitance matching spec. | Less suitable for high-speed SENT/FlexRay due to higher C and no ΔCd/Cd guarantee. | Select when cost sensitivity outweighs timing-critical bus requirements and 40 V clamping is acceptable for 5 V transceivers. |
| Vishay VEML6040 | Single-channel device; requires two units; 12 pF capacitance; AEC-Q101 qualified but not IVN-optimized. | Increases board area and BOM count; lacks integrated dual-channel symmetry for differential buses. | Prefer only if existing design uses discrete single-channel layout and cannot accommodate common-cathode footprint. |
Compared with NUP2114 and VEML6040, PESD2IVN24T-Q uniquely combines matched low capacitance, 33 V clamping, and dual-channel common-cathode integration-making it the optimal choice for space-constrained, timing-sensitive automotive IVN interfaces requiring single-component ESD hardening.

FAQ
What is the maximum peak pulse current rating for PESD2IVN24T-Q?
The rated peak pulse current (IPPM) is 3.5 A for an 8/20 µs waveform per IEC 61000-4-5. This value is measured from either pin 1 or pin 2 to pin 3 and represents the highest non-repetitive surge the device can safely clamp without degradation. It supports compliance with ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) test levels when used with proper PCB layout.
Does PESD2IVN24T-Q support bidirectional ESD protection on both channels?
Yes-each channel (pin 1–pin 3 and pin 2–pin 3) provides full bidirectional clamping, with symmetrical breakdown (25.5–35.5 V) and clamping behavior for both positive and negative transients. This is confirmed by V-I characteristic curves in Figures 3–6 of the datasheet and validated per IEC 61000-4-2 contact discharge testing in both polarities.
How is the common cathode (pin 3) intended to be connected in layout?
Pin 3 must be connected to a low-inductance ground plane-preferably via multiple vias directly beneath the SOT23 pad-to minimize transient loop inductance. Routing should avoid sharing this return path with noisy digital or power grounds. Layout guidelines in Section 10 specify placement within 2 mm of the protected connector and shortest possible trace lengths to maintain clamping effectiveness.
Is PESD2IVN24T-Q compatible with 3.3 V automotive transceivers?
Yes-the 24 V reverse standoff voltage and 33 V clamping ensure safe operation with 3.3 V transceivers (e.g., TCAN1042HV, STGM101) when used with appropriate series impedance. The 1 nA leakage prevents interference with bias networks, and 14–17 pF capacitance introduces negligible loading on 3.3 V differential receivers operating up to 5 Mbps.
