Product details
Overview
PESD1IVN27-AX from Nexperia is a bidirectional automotive-grade ESD protection diode in SOD323 package, designed to safeguard in-vehicle network (IVN) bus lines against ±30 kV IEC 61000-4-2 and ISO 10605 transients. It features 27 V reverse stand-off voltage, 36 V clamping voltage at 3 A, <1 nA leakage, and AEC-Q101 qualification for CAN, LIN, FlexRay, and SENT interfaces.
For engineers reviewing the PESD1IVN27-AX datasheet, PESD1IVN27-AX pinout, PESD1IVN27-AX application, or PESD1IVN27-AX equivalent, this page delivers verified electrical parameters, automotive transient compliance data, dual-cathode pin mapping, and validated alternatives for IVN line protection design-in.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure optimized for low-capacitance (14–17 pF) and fast response to ESD events on differential or single-ended IVN buses. Its 0.2 Ω dynamic resistance ensures minimal voltage overshoot during 8/20 μs surge pulses up to 3 A.
It meets ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V), supports junction temperatures up to 150 °C, and maintains stable clamping performance across −55 °C to +150 °C ambient range - critical for under-hood and body-control module deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 27 V - Maximum continuous operating voltage before conduction; sets bus line compatibility with 24 V automotive systems. |
| Clamping Voltage | 36 V at 3 A - Peak voltage seen by protected IC during 8/20 μs surge; ensures downstream transceivers remain within safe ABSMAX limits. |
| ESD Withstand | ±30 kV per IEC 61000-4-2 & ISO 10605 - Validated immunity to contact discharge with 330 pF/330 Ω network; exceeds automotive OEM requirements. |
| Diode Capacitance | 14–17 pF at 0 V - Low parasitic loading preserves signal integrity on high-speed IVN buses like CAN FD and SENT. |
| Leakage Current | <1 nA at 27 V - Negligible DC load on bus lines; avoids battery drain in always-on vehicle modules. |
| Dynamic Resistance | 0.2 Ω - Enables rapid energy shunting with minimal IR drop during transient events. |
Pinout & Package
Package: SOD323 (SC-76), surface-mounted, 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch. Cathode-bar marking denotes Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to protected line (e.g., CAN_H or LIN); forms one half of bidirectional clamp path. |
| 2 | Cathode (Diode 2) | Connects to same protected line; enables symmetrical clamping for both positive and negative ESD polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Single-device protection against ±8 kV contact discharge without external polarity management. |
| AEC-Q101 Qualified | Validated for automotive temperature cycling, humidity, and mechanical stress - suitable for engine bay and chassis-mounted ECUs. |
| Low Capacitance (14–17 pF) | Minimizes signal distortion on 1 Mbps CAN and 100+ kbps SENT lines without requiring layout compensation. |
| Ultra-Low Leakage (<1 nA) | Eliminates measurable current draw on always-active IVN nodes - critical for low-power sleep-mode operation. |
| ISO 7637-3 Compliance | Withstands repetitive load-dump and inductive-switching transients (Pulse a/b) without degradation. |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines in powertrain control units exposed to ESD during service or assembly. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: Limits clamped voltage to ≤36 V during 3 A surge, keeping TJA1042/TJA1051 transceivers within safe operating area. | Use Scenario: Shielding LIN slave nodes (e.g., door modules, sensors) from ESD coupling via harness connectors. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on single-wire LIN bus, mounted adjacent to transceiver input. Use Value: 14–17 pF capacitance avoids timing skew on 19.2 kbps LIN frames; <1 nA leakage prevents battery drain in parked state. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Safeguarding FlexRay physical layer in ADAS domain controllers where ESD-induced bit errors must be eliminated. IC Role / Device Role / Timing Role: Dual-cathode TVS on differential FlexRay A/B lines, minimizing common-mode impedance imbalance. Use Value: Symmetrical clamping preserves differential signal fidelity at 10 Mbps; 0.2 Ω Rdyn ensures sub-10 ns response to ESD onset. | Use Scenario: Protecting SENT output pins of pressure/temperature sensors in engine compartments subject to repeated handling ESD. IC Role / Device Role / Timing Role: Point-of-entry ESD suppressor on SENT signal line, placed before series resistor to MCU input. Use Value: 27 V VRWM matches typical SENT supply rails; 36 V VCL prevents latch-up in NXP MC33771 or similar analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC27A | Unidirectional, higher clamping (47 V @ 3 A), larger SMC package (7.1 mm × 6.2 mm) | Requires two devices for bidirectional protection; unsuitable for space-constrained IVN nodes | Select only if board area permits and unidirectional-only protection suffices. |
| Vishay VMM10MT27 | Bidirectional, same 27 V VRWM, but higher capacitance (35 pF) and no AEC-Q101 certification | Not qualified for automotive use; limited to industrial or consumer IVN derivatives | Use only in non-automotive designs where AEC-Q101 is not mandated. |
Compared with SZ1.5SMC27A and VMM10MT27, PESD1IVN27-AX uniquely combines AEC-Q101 qualification, SOD323 footprint, bidirectional 36 V clamping, and 14–17 pF capacitance - making it the only drop-in solution for space- and reliability-critical automotive IVN nodes.

FAQ
What is the maximum peak pulse current rating for PESD1IVN27-AX?
The rated peak pulse current (IPPM) is 3 A under 8/20 μs exponential decay waveform per IEC 61000-4-5. This value is validated in limiting values Table 5 and confirmed in Characteristics Table 6 for clamping voltage testing at exactly 3 A.
Does PESD1IVN27-AX support bidirectional ESD protection with a single device?
Yes - its dual-cathode SOD323 configuration enables symmetrical clamping for both positive and negative ESD transients without external components. Pin 1 and Pin 2 serve as independent cathodes tied to the same protected line, forming an integrated bidirectional TVS path.
Is PESD1IVN27-AX qualified for under-hood automotive environments?
Yes - it is AEC-Q101 qualified and rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to +150 °C. Its construction and test validation per ISO 7637-3 Pulse a/b confirm suitability for engine compartment and transmission control unit deployments.
How does the 14–17 pF capacitance impact CAN FD signal integrity?
This capacitance range introduces negligible rise-time degradation on CAN FD (up to 5 Mbps): measured propagation delay increase is <0.5 ns over 1 m trace, well within ISO 11898-2 margin. Layout best practices (short traces, ground plane) maintain signal eye opening >85% at 2 Mbps.
