Product details
Overview
PESD24VV2BT-Q from Nexperia is a bidirectional double ESD protection diode in SOT23 package, designed to protect two low-speed data lines against IEC 61000-4-2 ESD events up to ±30 kV and 8/20 µs surges up to 3.5 A peak pulse current, with 24 V reverse stand-off voltage and 33 V clamping voltage at 3.5 A - deployed in automotive infotainment interfaces and CAN/LIN bus signal lines.
For engineers reviewing the PESD24VV2BT-Q datasheet, PESD24VV2BT-Q pinout, PESD24VV2BT-Q application, or PESD24VV2BT-Q equivalent, key selection criteria include bidirectional clamping performance, sub-17 pF line-to-ground capacitance, AEC-Q101 qualification, ultra-low 1 nA leakage at 24 V, and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual-channel, common-cathode ESD suppressor architecture where pins 1 and 2 serve as independent cathodes for two symmetrical bidirectional protection paths, each referenced to shared pin 3 (K). It operates without biasing and responds within <1 ns to ESD transients.
Clamping behavior is defined by dynamic resistance of 0.2 Ω and guaranteed VCL ≤33 V at IPPM = 3.5 A (8/20 µs), while maintaining low 14–17 pF capacitance per channel (measured pin-to-pin 1/2 vs. 3) to preserve signal integrity on lines up to 10 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 24 V - Maximum continuous working voltage before conduction; ensures no leakage during normal 24 V rail operation. |
| Clamping Voltage | 33 V at 3.5 A (8/20 µs) - Limits transient voltage seen by downstream ICs to safe levels below typical 36 V absolute max ratings. |
| ESD Withstand | ±30 kV contact discharge (IEC 61000-4-2) - Survives worst-case human-body-model ESD events without degradation. |
| Diode Capacitance | 14–17 pF (1 MHz, 0 V bias) - Low enough to avoid signal distortion on RS-485, LIN, or analog sensor lines. |
| Leakage Current | 1 nA at 24 V - Negligible power loss and minimal impact on high-impedance sensing circuits. |
| Peak Pulse Current | 3.5 A (8/20 µs waveform) - Handles surge energy from lightning-induced or inductive switching transients. |
| Package | SOT23 (TO-236AB) - 2.9 × 1.3 × 1.0 mm surface-mount footprint compatible with standard reflow processes. |
Pinout & Package
SOT23 plastic surface-mount package (TO-236AB), 3-terminal, 1.9 mm pitch, body dimensions 2.9 mm × 1.3 mm × 1.0 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line; forms bidirectional clamp path to common cathode (pin 3). |
| 2 | K2 (cathode of diode 2) | Connects to second protected line; forms independent bidirectional clamp path to common cathode (pin 3). |
| 3 | K (common cathode) | Shared return node tied to system ground; enables compact dual-line protection with single ground connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin environments (-55 °C to +150 °C junction temperature). |
| Bidirectional dual-channel topology | Protects two independent signal lines with one device, reducing PCB area versus discrete single-diode solutions. |
| Ultra-low capacitance (14–17 pF) | Preserves rise time and signal fidelity on low-speed buses such as LIN, SENT, or analog sensor outputs. |
| Sub-1 nA leakage at VRWM | Eliminates measurable loading on high-impedance voltage dividers or battery-monitoring inputs. |
Applications
| Automotive LIN Bus Protection | Industrial RS-485 Interface |
|---|---|
|
Use Scenario: Protecting LIN transceiver I/O pins in door modules and seat control units exposed to ESD during assembly and service. IC Role / Device Role: Bidirectional transient voltage suppressor placed between LIN bus line and transceiver input, referenced to chassis ground. Use Value: Prevents latch-up or damage to transceivers rated for only ±8 kV HBM by clamping ±30 kV contact ESD to ≤33 V. |
Use Scenario: Safeguarding RS-485 receiver inputs in factory automation PLC I/O modules subject to cable-borne surges. IC Role / Device Role: Line-to-ground ESD protector on differential pair, mounted adjacent to connector to minimize inductance. Use Value: Maintains signal integrity with 17 pF capacitance while limiting 3.5 A surge transients to safe voltage levels for 3.3 V or 5 V receivers. |
| Consumer USB 2.0 ID Line | Automotive Analog Sensor Interface |
|
Use Scenario: ESD protection for USB 2.0 ID pin in portable diagnostic tools connecting to vehicle OBD-II ports. IC Role / Device Role: Single-point protection on ID line referenced to system ground, leveraging low capacitance to avoid USB enumeration issues. Use Value: Enables robust hot-plug operation with <17 pF loading - well below USB 2.0's 120 pF total load limit. |
Use Scenario: Shielding NTC thermistor or pressure sensor output lines in engine control units from handling ESD. IC Role / Device Role: Ground-referenced clamp on analog voltage output line, placed directly at sensor connector entry point. Use Value: Adds <1 nA leakage - negligible error in 10 kΩ–100 kΩ sensor divider networks - while surviving repeated ±30 kV discharges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMF24AQT1G | Unidirectional, single-channel, higher 24 V VRWM but no dual-line integration; 35 V VCL at 3.5 A. | Requires two devices for dual-line protection; larger board area and higher BOM count. | Select when legacy unidirectional design exists or when higher surge rating (1500 W) outweighs layout efficiency. |
| Vishay VE14A24A | Bi-directional dual-channel like PESD24VV2BT-Q, but 20 pF capacitance and AEC-Q200 (not Q101) qualified. | Higher capacitance may degrade edge rate on >5 Mbps lines; Q200 qualification covers passive components, not discrete semiconductors. | Prefer for non-automotive industrial use where AEC-Q101 is not mandated and 20 pF is acceptable. |
Compared with SZ1.5SMF24AQT1G and VE14A24A, PESD24VV2BT-Q uniquely combines AEC-Q101 qualification, 14–17 pF capacitance, and integrated dual-channel topology - enabling smaller footprint, lower leakage, and automotive-grade reliability in a single SOT23 device.

FAQ
Is PESD24VV2BT-Q suitable for protecting high-speed USB 3.0 or HDMI lines?
No. Its 14–17 pF capacitance is optimized for low-speed interfaces (<10 Mbps), such as LIN, RS-485, or analog sensors. High-speed protocols like USB 3.0 or HDMI require sub-1 pF capacitance to prevent signal integrity loss - this device would cause excessive attenuation and jitter.
Can pin 3 be left floating or connected to a voltage rail instead of ground?
No. Pin 3 is the common cathode and must be connected directly to a low-inductance system ground plane. Floating or biasing it violates the device's clamping mechanism and prevents proper ESD current diversion, risking failure during transients.
What is the maximum recommended PCB trace length between PESD24VV2BT-Q and the protected connector?
Trace length should not exceed 3 mm from device to connector pad. Longer traces add inductance that degrades clamping response - measured TLP data shows >3 mm increases clamped voltage by ≥15 % at 3.5 A due to L·di/dt effects.
Does PESD24VV2BT-Q require external series resistors for optimal ESD protection?
No external resistor is required for basic ESD compliance. However, a 0 Ω or 10 Ω series resistor may be added upstream to limit peak current during very fast transients (<1 ns rise time), though this is rarely needed given its <1 ns response and 0.2 Ω dynamic resistance.
