Product details
Overview
PESD36VL2BT-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 ±22 kV IEC 61000-4-2 ESD strikes, with 36 V reverse standoff voltage, 47 V clamping at 16 A, and 10 pF capacitance. It operates across –55 °C to +150 °C and is AEC-Q101 qualified.
For engineers reviewing the PESD36VL2BT-QR datasheet, PESD36VL2BT-QR pinout, PESD36VL2BT-QR application, or PESD36VL2BT-QR equivalent, key selection criteria include bidirectional clamping performance, low capacitance for high-speed bus integrity, AEC-Q101 qualification status, and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual unidirectional TVS configuration with shared cathode (Pin 3), enabling independent transient suppression on two signal lines (Pins 1 and 2) referenced to a common ground path. Its low dynamic resistance (0.8 Ω) ensures rapid voltage clamping during sub-100 ns ESD events.
The 10 pF diode capacitance at 0 V bias and stable clamping behavior up to 16 A (TLP) support reliable operation on 24 V board nets and high-speed protocols including CAN-FD (up to 5 Mbps) and SENT without signal distortion or timing skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Ensures no conduction during normal 24 V automotive bus operation, including load-dump transients. |
| Clamping Voltage | 47 V at 16 A (100 ns TLP) - Limits peak transient voltage to safe levels for downstream CAN transceivers rated ≤ 48 V abs max. |
| ESD Withstand | ±22 kV contact discharge (IEC 61000-4-2) - Meets stringent automotive ESD immunity requirements for exterior connectors and harness interfaces. |
| Diode Capacitance | 10 pF at 1 MHz, 0 V - Minimizes signal rise-time degradation on CAN-FD and SENT buses operating up to 2 Mbps. |
| Junction Temperature Range | –55 °C to +150 °C - Supports under-hood deployment in engine control units and body electronics modules. |
| AEC-Q101 Qualification | Qualified - Confirmed reliability for automotive applications per stress test standard for discrete semiconductors. |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm, 1.9 mm lead pitch), 3-terminal configuration with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Connects to first protected line (e.g., CANH); anode tied internally to Pin 3 for unidirectional clamping to ground. |
| 2 | K2 (Cathode of Diode 2) | Connects to second protected line (e.g., CANL); enables independent transient suppression on dual-bus architecture. |
| 3 | CC (Common Cathode) | Ground reference terminal; must be connected directly to low-inductance chassis or power ground for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection topology | Single SOT23 device protects two independent bus lines (e.g., CANH/CANL) with isolated cathodes and shared ground return. |
| Low clamping voltage | 47 V at 16 A TLP pulse ensures robust protection margin below absolute maximum ratings of automotive transceivers. |
| Automotive-qualified leakage | ≤50 nA reverse leakage at 36 V enables stable DC biasing without loading 24 V supply rails or sensor references. |
| High-speed bus compatibility | 10 pF capacitance preserves signal integrity on CAN-FD (5 Mbps) and SENT (125 kbps) without measurable edge rounding. |
Applications
| CAN-FD Bus Protection | FlexRay Physical Layer |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface of ADAS domain controller supporting CAN-FD up to 5 Mbps.

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 |
|---|---|---|---|
| ESD56051D05-2/TR | Higher capacitance (15 pF), lower clamping (40 V at 12 A), same SOT23-3L package | Better suited for lower-speed LIN or legacy CAN (125 kbps); less ideal for CAN-FD due to bandwidth limitation | Select when system-level ESD testing shows margin beyond 40 V clamping and bus speed ≤ 1 Mbps. |
| TPD2EUSB30DRYR | Lower standoff (5.5 V), higher capacitance (1.3 pF per line), optimized for USB 3.0, not AEC-Q101 qualified | Designed for consumer USB interfaces only; lacks automotive temperature range and qualification | Not recommended for automotive use; only consider for non-automotive prototypes requiring ultra-low capacitance. |
Compared with ES56051D05-2/TR and TPD2EUSB30DRYR, PESD36VL2BT-QR uniquely balances 36 V standoff, 10 pF capacitance, and AEC-Q101 qualification-making it the only option validated for CAN-FD and 24 V truck systems requiring simultaneous high-voltage tolerance and high-speed signal integrity.

FAQ
What is the maximum peak pulse current rating for PESD36VL2BT-QR?
The rated peak pulse current (IPPM) is 3.2 A under 8/20 µs waveform per IEC 61000-4-5. This value applies to each channel (Pin 1→3 and Pin 2→3) independently. The device is tested with ten non-repetitive ESD pulses at ±22 kV per IEC 61000-4-2, confirming robust single-event survivability beyond its rated IPPM.
Can PESD36VL2BT-QR be used for bidirectional signal lines like RS-485?
No - PESD36VL2BT-QR uses a dual unidirectional configuration (K1 and K2 anodes tied internally to CC), making it suitable only for single-ended or differential lines referenced to ground, such as CANH/CANL. It does not provide symmetrical clamping for true bidirectional buses like RS-485, which require dedicated bidirectional TVS arrays or specialized protection ICs.
Is the 10 pF capacitance measured per diode or total?
The 10 pF diode capacitance (Cd) is specified per diode - i.e., between Pin 1 and Pin 3, and separately between Pin 2 and Pin 3 - measured at 1 MHz and 0 V reverse bias. There is no coupling capacitance between Pins 1 and 2; inter-pin capacitance is not characterized and is negligible (<0.2 pF) per package parasitic modeling.
Does PESD36VL2BT-QR require a heatsink in typical automotive applications?
No heatsink is required. The device handles transient energy via short-duration pulse dissipation (≤100 ns), not steady-state power. Its 150 °C maximum junction temperature and low thermal resistance (RθJA ≈ 300 K/W for SOT23 on 1-in² 1-oz copper) ensure safe operation without additional thermal management under all specified surge and ESD conditions.
