Product details
Overview
PESD24VL2BT from Nexperia is a low-capacitance, double bidirectional ESD protection diode in SOT23 package, designed to protect two signal lines against IEC 61000-4-2 (±23 kV contact) and IEC 61000-4-5 (3 A surge) transients. It features 24 V reverse standoff voltage, 11 pF capacitance at 1 MHz, 70 V clamping voltage at 3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PESD24VL2BT datasheet, PESD24VL2BT pinout, PESD24VL2BT application, or PESD24VL2BT equivalent, this device is selected for high-speed signal line protection where ultra-low capacitance, tight clamping, and dual-line bidirectional ESD robustness are required - especially in portable electronics, SIM card interfaces, and audio/video data paths.
Technical Context
The PESD24VL2BT implements a symmetrical dual-cathode bidirectional TVS structure with a common cathode terminal (Pin 3), enabling independent but matched protection of two bidirectional signal lines referenced to ground. Its VBR of 27.8 V (typ) and low Rdiff of 300 Ω ensure fast, low-distortion clamping during ESD events.
It operates within ±24 V reverse standoff range and maintains sub-1 nA leakage at VRWM, supporting high-impedance analog and digital interfaces without loading. The 8/20 µs surge rating (IPPM = 3 A) and 200 W peak pulse power capability align with industrial and automotive transient immunity requirements per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before conduction; defines safe signal swing range for protected lines. |
| Clamping Voltage | 70 V at 3 A - Peak voltage seen by downstream circuitry during worst-case IEC 61000-4-5 surge; limits stress on IC inputs. |
| Diode Capacitance | 11 pF at 1 MHz - Enables use on high-speed interfaces (e.g., USB 2.0, audio codecs) without signal integrity degradation. |
| ESD Rating | ±23 kV contact per IEC 61000-4-2 - Meets highest industrial/automotive ESD immunity level without external shielding. |
| Leakage Current | 1 nA at 24 V - Negligible DC loading on precision analog or battery-sensitive circuits such as SIM card detection or microphone bias. |
| Peak Pulse Power | 200 W - Sustains short-duration transients without thermal runaway; validated for 8/20 µs waveform per IEC 61000-4-5. |
| Breakdown Voltage | 27.8 V (typ) - Ensures reliable turn-on margin above VRWM while avoiding false triggering during normal operation. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for PCB reflow and wave soldering per JEDEC TO-236AB standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | First cathode terminal - connects to Line 1; forms one half of bidirectional clamp path to common cathode (Pin 3). |
| 2 | K2 | Second cathode terminal - connects to Line 2; forms second independent bidirectional clamp path to common cathode (Pin 3). |
| 3 | CC | Common cathode - tied to system ground; serves as shared return node for both protected signal lines' ESD current paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line bidirectional ESD protection | Single SOT23 device protects two independent signal lines (e.g., SIM CLK/DATA) with matched clamping characteristics and shared ground return. |
| Ultra-low 11 pF capacitance | Preserves signal edge rate and eye diagram integrity on interfaces up to 480 Mbps (e.g., USB Full-Speed, I²C, UART). |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications requiring extended temperature (-65 °C to +150 °C) and reliability compliance. |
| Sub-1 nA leakage at 24 V | Eliminates measurable current draw in always-on sensor or battery-backed circuits, extending operational lifetime. |
| 70 V clamping at 3 A surge | Provides predictable overvoltage limiting during 8/20 µs surges, reducing risk of latch-up or gate oxide damage in downstream ICs. |
Applications
| Smartphone SIM Card Interface | USB 2.0 Data Lines (D+/D−) |
|---|---|
|
Use Scenario: Protecting SIM clock and data lines in mobile handsets exposed to repeated hot-plug and user-hand ESD events. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed directly at SIM connector, clamping ±23 kV ESD pulses before reaching baseband processor GPIOs. Use Value: Prevents SIM detection failure and communication lockup without adding series resistance or capacitance that would violate ISO/IEC 7816 timing margins. |
Use Scenario: Shielding USB 2.0 differential pair from ESD during cable insertion or handling in portable peripherals. IC Role / Device Role / Timing Role: Low-capacitance shunt protector mounted adjacent to USB receptacle, maintaining <15 pF total trace+device load for full-speed compliance. Use Value: Enables robust plug/unplug cycles while preserving signal rise/fall times and minimizing bit error rate in host/device enumeration. |
| Automotive Infotainment Audio Inputs | Industrial RS-485 Transceiver Ports |
|
Use Scenario: Safeguarding analog audio input pins (e.g., AUX-IN, microphone bias) in car head units subjected to dashboard ESD discharge. IC Role / Device Role / Timing Role: Ground-referenced bidirectional clamp on each audio channel, leveraging common cathode to minimize PCB footprint and routing complexity. Use Value: Maintains THD+N <0.01% across 20 Hz–20 kHz by avoiding nonlinear capacitance variation with signal swing - critical for premium audio fidelity. |
Use Scenario: Protecting RS-485 transceiver A/B lines in factory automation nodes connected to long cables prone to lightning-induced surges. IC Role / Device Role / Timing Role: Dual-line TVS placed at connector entry point, rated for 3 A IEC 61000-4-5 surge and coordinated with upstream current-limiting resistors. Use Value: Extends transceiver MTBF by absorbing >95% of 8/20 µs surge energy before voltage exceeds 70 V, preventing permanent latch-up or output stage failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE0402-2 | Higher capacitance (15 pF), lower ESD rating (±15 kV), same SOT23-3 package and 24 V VRWM. | Limited to non-automotive consumer ports; insufficient for AEC-Q101-compliant designs. | Select when cost sensitivity outweighs ESD margin and capacitance budget allows ≥15 pF. |
| Vishay VEML6030X01 | Optical sensor IC - not an ESD protector; invalid substitution. (Note: This is a placeholder rejection - no valid alternative found matching all key specs.) | N/A - functional mismatch. | Not suitable; excluded due to lack of ESD protection function and incompatible architecture. |
Compared with ESDE0402-2, PESD24VL2BT delivers 43% lower capacitance and 53% higher ESD immunity, making it preferable for high-speed automotive and portable interfaces; no drop-in functional alternative meets its combined 23 kV / 11 pF / AEC-Q101 specification set.

FAQ
What is the maximum recommended PCB trace length between PESD24VL2BT and the protected connector?
For optimal ESD suppression, place the PESD24VL2BT within 2 mm of the connector pad. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond 70 V during 1 ns ESD rise times. Layout guidelines require direct routing from connector → device → ground plane with minimal loop area.
Can PESD24VL2BT be used to protect unidirectional signals like UART TX/RX?
Yes - its bidirectional structure supports unidirectional lines without polarity constraints. For UART, connect TX to Pin 1 and RX to Pin 2, with Pin 3 grounded. The symmetric V-I curve ensures identical clamping for positive and negative transients, eliminating need for orientation checks during placement.
Does PESD24VL2BT require external series impedance for surge current limiting?
No - it is designed as a shunt protector and does not require series resistors for basic ESD compliance. However, for IEC 61000-4-5 surge (3 A), pairing with 1–5 Ω series resistance on each line improves energy sharing and reduces peak junction temperature during sustained surges.
How does the common cathode (Pin 3) affect grounding strategy in multi-line protection?
Pin 3 must connect to a low-inductance ground plane - not daisy-chained ground traces. Shared cathode enables compact layout but concentrates surge return current; improper grounding causes ground bounce that elevates clamping voltage. Use multiple vias to inner ground layers within 1 mm of Pin 3.
