Product details
Overview
PESD36VU2BT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed to safeguard two in-vehicle network lines (e.g., CAN-FD, FlexRay) against ±15 kV IEC 61000-4-2 ESD events, with 36 V reverse standoff voltage, 4.3 pF capacitance, and 65 V clamping at 16 A TLP pulse.
For engineers reviewing the PESD36VU2BT-QR datasheet, PESD36VU2BT-QR pinout, PESD36VU2BT-QR application, or PESD36VU2BT-QR equivalent, key selection criteria include AEC-Q101 qualification, low clamping voltage under high-current transients, bidirectional protection architecture, and layout-critical placement near connectors for CAN/FlexRay bus integrity.
Technical Context
This device implements a common-cathode dual-diode topology (K1/K2 → CC), enabling symmetrical bidirectional clamping on two independent signal lines referenced to a shared ground return path. Its design targets fast transient suppression with sub-1 ns rise time response and dynamic resistance of 1.3 Ω under 10 A TLP stress.
It operates within automotive ambient temperature range (−55 °C to +150 °C), supports 24 V board net systems, and meets ISO 10605 (15 kV, 150/330 pF) and IEC 61000-4-5 surge immunity requirements-critical for robustness in truck and passenger vehicle ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Ensures no conduction during normal 24 V bus operation with margin against ripple and load dump. |
| Clamping Voltage (16 A TLP) | 65 V - Limits peak transient voltage seen by downstream CAN transceiver I/O pins during ESD events. |
| Diode Capacitance | 4.3 pF - Minimizes signal distortion and timing skew on high-speed CAN-FD (5 Mbps) and FlexRay (10 Mbps) buses. |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact - Meets automotive OEM ESD immunity requirements without external shielding or filtering. |
| AEC-Q101 Qualified | Yes - Validated for automotive use per stress test standard, including temperature cycling, HTRB, and ESD reliability testing. |
| Peak Pulse Current (8/20 µs) | 1.5 A - Supports basic surge immunity per IEC 61000-4-5 Level 3 (1 kV line-to-ground) in compact SOT23 footprint. |
Pinout & Package
SOT23 plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height. RoHS-compliant, lead-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line (e.g., CANH); forms cathode-side clamp path to common cathode. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line (e.g., CANL); enables independent clamping on dual bus signals. |
| 3 | CC (common cathode) | Single ground-return node for both diodes; must be routed to low-inductance chassis or system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional dual-line protection | Two independent ESD paths share one ground terminal-reduces PCB area vs. discrete diodes and avoids asymmetry in clamping behavior. |
| Low dynamic resistance | 1.3 Ω - Enables faster energy dissipation and lower clamping overshoot during nanosecond-scale ESD pulses. |
| Ultra-low capacitance | 4.3 pF - Preserves signal integrity on high-speed differential buses without degrading eye diagram or increasing bit error rate. |
| AEC-Q101 qualification | Validated across temperature cycling, high-temp reverse bias, and ESD reliability tests-ensures long-term field reliability in engine bay and ADAS modules. |
Applications
| CAN-FD Bus Protection | FlexRay Network Protection |
|---|---|
Use Scenario: Protecting CAN-FD transceivers in ADAS domain controllers exposed to ESD during service port access or connector mating. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at OBD-II or module connector, clamping ESD before it reaches transceiver I/O pins. Use Value: Maintains 5 Mbps data integrity by limiting clamping voltage to ≤65 V while adding only 4.3 pF loading per line. | Use Scenario: Safeguarding FlexRay physical layer in powertrain control units where electromagnetic noise and ESD coexist in harsh under-hood environments. IC Role / Device Role / Timing Role: Dual-line ESD clamp referenced to common ground, ensuring matched clamping thresholds on both FRAY+ and FRAY− lines. Use Value: Prevents latch-up or damage in FlexRay PHY ICs during ±15 kV contact discharge, validated per ISO 10605. |
| 24 V Truck Network Protection | SENT Sensor Interface Protection |
Use Scenario: ESD hardening of LIN/CAN gateways in commercial vehicle telematics modules operating on 24 V board nets with wide voltage tolerance. IC Role / Device Role / Timing Role: Reverse-biased protection diode pair handling transients up to 36 V standoff, compatible with 24 V nominal supply with ±20 % variation. Use Value: Eliminates need for higher-voltage TVS arrays; reduces BOM count and PCB space versus discrete solutions. | Use Scenario: Shielding single-wire SENT (SAE J2716) sensor interfaces in engine management systems from ESD coupling via harness routing near ignition coils. IC Role / Device Role / Timing Role: Low-capacitance clamp on SENT signal line referenced to chassis ground, preserving <1 µs pulse timing accuracy. Use Value: Enables reliable 12-bit sensor resolution by preventing ESD-induced pulse edge jitter or false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD321-2W5 | Higher VRWM (32 V), lower VCL (55 V @ 16 A), same SOT23-3L package and AEC-Q101 rating. | Better suited for 12 V systems; less margin for 24 V bus ripple; identical layout compatibility. | Select when tighter clamping is prioritized over 36 V standoff headroom in 12 V domains. |
| TPD2EUSB30DRYR | Lower capacitance (1.1 pF), USB 3.0 optimized, not AEC-Q101 qualified, different pinout (2-channel, no common cathode). | Not suitable for automotive; intended for consumer USB/MIPI; requires redesign for ground referencing. | Reject for automotive use-lacks qualification, different topology, and insufficient surge rating for ISO 10605. |
Compared with ESD321-2W5 and TPD2EUSB30DRYR, PESD36VU2BT-QR uniquely balances 36 V standoff for 24 V truck systems, AEC-Q101 compliance, and common-cathode dual-line integration-making it optimal for CAN-FD and FlexRay where bus voltage margin and layout simplicity are critical.

FAQ
What is the maximum junction temperature rating for PESD36VU2BT-QR?
The absolute maximum junction temperature is 150 °C, consistent with AEC-Q101 qualification requirements. This allows operation in under-hood environments where ambient temperatures reach 125 °C, provided PCB thermal design maintains junction-to-ambient thermal resistance below 20 K/W.
Can PESD36VU2BT-QR protect both CANH and CANL simultaneously?
Yes-its common-cathode dual-diode structure (pins 1 and 2 as independent cathodes, pin 3 as shared cathode) enables simultaneous, matched clamping on both differential lines. Each channel clamps independently to the same reference, preserving differential signal integrity during ESD events.
Is the 4.3 pF capacitance measured at DC bias or AC signal conditions?
The 4.3 pF typical capacitance is measured at 1 MHz with −2.5 V reverse bias and 25 °C ambient temperature, per Table 6. It remains stable across the −36 V to 0 V operating range, making it suitable for high-frequency CAN-FD and FlexRay signaling without introducing phase shift or attenuation.
Does PESD36VU2BT-QR require external series impedance for optimal performance?
No external series resistor is required for ESD protection function. However, layout best practices mandate placing the device within 2 mm of the connector, using short direct traces to pins 1/2, and connecting pin 3 to a low-inductance ground plane-no added impedance improves clamping speed or effectiveness.
