Product details
Overview
PESD24VV2BTR from Nexperia is a bidirectional double ESD protection diode in SOT23 package, designed to protect two low-speed data lines against ±30 kV IEC 61000-4-2 ESD events, with 24 V reverse stand-off voltage, 33 V clamping at 3.5 A peak pulse, and 14–17 pF capacitance - deployed in automotive infotainment interfaces and CAN/LIN transceiver I/O protection.
For engineers reviewing the PESD24VV2BTR datasheet, PESD24VV2BTR pinout, PESD24VV2BTR application, or PESD24VV2BTR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive-grade AEC-Q101 qualification status, and real-world layout guidance for ESD transient suppression on dual-line interfaces.
Technical Context
This device implements a dual-cathode, common-cathode topology with two independent bidirectional ESD clamps sharing a single ground-referenced cathode (Pin 3). Each clamp provides symmetrical breakdown above ±25.5 V and clamps transients to ≤33 V at 3.5 A (8/20 µs), enabling robust protection without signal distortion on adjacent lines.
Its ultra-low leakage (<1 nA at 24 V) and low dynamic resistance (0.2 Ω) ensure minimal impact on signal integrity in low-speed analog and digital buses. The 14–17 pF capacitance-measured from Pin 1 or 2 to Pin 3-is optimized for interfaces up to 10 Mbps where capacitive loading must remain below 20 pF.
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) - Peak voltage seen by protected IC during worst-case surge; stays below typical 36 V IO tolerance. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - Withstands automotive-level ESD stress without degradation over 10 pulses. |
| Diode Capacitance | 14–17 pF at 0 V, 1 MHz - Measured pin-to-common-cathode; enables use on RS-485, LIN, and analog sensor lines without bandwidth loss. |
| Leakage Current | <1 nA at 24 V - Negligible DC load on high-impedance inputs; preserves battery life in always-on automotive modules. |
| Dynamic Resistance | 0.2 Ω - Low impedance during clamping reduces voltage overshoot and improves energy dissipation efficiency. |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard - Validated for under-hood temperature cycling (-55 °C to +150 °C). |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body; marked "FL%" (site code placeholder); RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Connects to Line 1; forms bidirectional clamp between Line 1 and common cathode (Pin 3/GND). |
| 2 | K2 (Cathode of Diode 2) | Connects to Line 2; forms independent bidirectional clamp between Line 2 and common cathode (Pin 3/GND). |
| 3 | K (Common Cathode) | Ground reference node; must be tied directly to low-inductance PCB ground plane for effective transient return path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line ESD protection in single SOT23 | Reduces board area vs. two discrete diodes; eliminates inter-device timing skew in differential or parallel line protection. |
| Ultra-low capacitance (14–17 pF) | Preserves signal rise/fall times on 1–10 Mbps buses; avoids false triggering or attenuation in analog sensor inputs. |
| Sub-1 nA leakage at VRWM | Enables use on high-Z nodes (e.g., microcontroller wake-up pins, thermistor dividers) without DC error or power drain. |
| AEC-Q101 qualification | Validated for automotive ambient and junction temperatures (−55 °C to +150 °C); supports 15-year vehicle service life. |
| Low clamping voltage (33 V @ 3.5 A) | Protects 3.3 V/5 V/24 V interface ICs with margin below absolute maximum ratings; minimizes risk of secondary latch-up. |
Applications
| Automotive LIN Bus Protection | Industrial RS-485 Transceiver I/O |
|---|---|
Use Scenario: Protecting LIN slave node transceivers (e.g., window lift control, seat position sensors) exposed to cable harness ESD. IC Role / Device Role / Timing Role: Bidirectional transient clamp placed at connector entry point, shunting ESD current from LIN bus to chassis ground. Use Value: Prevents transceiver latch-up or permanent damage from ±30 kV contact discharge while maintaining <10 ns response time and <17 pF loading. |
Use Scenario: Safeguarding RS-485 driver/receiver pins in factory automation PLC I/O modules subject to field wiring transients. IC Role / Device Role / Timing Role: Dual-line protector on A/B differential pair, referenced to local system ground to suppress common-mode surges. Use Value: Enables reliable 250 kbps communication under 3.5 A surge conditions without signal distortion or receiver offset shift. |
| Consumer USB 2.0 D+/D− Lines | Automotive Analog Sensor Inputs |
Use Scenario: ESD hardening of USB 2.0 upstream ports on infotainment head units handling frequent plug/unplug cycles. IC Role / Device Role / Timing Role: Common-cathode clamp across D+ and D−, with Pin 3 grounded to minimize differential mode noise injection. Use Value: Maintains 480 Mbps eye diagram integrity via 17 pF max capacitance and sub-33 V clamping during ±8 kV air discharge. |
Use Scenario: Protecting NTC thermistor or potentiometer wiper inputs in HVAC control modules from dashboard ESD events. IC Role / Device Role / Timing Role: Low-leakage clamp on high-impedance analog input paths, referenced to ADC ground to avoid bias current errors. Use Value: Ensures <1 µV offset drift under ESD stress due to <1 nA IRM and absence of forward conduction during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMF24A | Unidirectional, single-channel, higher capacitance (100 pF), higher clamping (48 V @ 3.5 A) | Requires two devices for dual-line protection; unsuitable for bidirectional buses like LIN or USB | Select only when protecting unidirectional 24 V supply rails-not signal lines. |
| Vishay VEML6030X01 | Optical sensor IC-not an ESD diode-no clamping or surge capability | Not functionally comparable; serves ambient light sensing, not circuit protection | Exclude from ESD protection BOMs; misapplication risks system vulnerability. |
Compared with SZ1.5SMF24A and VEML6030X01, PESD24VV2BTR uniquely delivers true bidirectional, dual-line protection in one SOT23 with automotive qualification, sub-20 pF loading, and guaranteed 30 kV ESD immunity-making it the only valid choice for space-constrained, safety-critical signal line hardening.

FAQ
What is the maximum operating temperature for PESD24VV2BTR?
The device supports junction temperatures up to +150 °C and ambient operating range from −55 °C to +150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests - making it suitable for under-hood automotive modules and industrial motor drives.
Can PESD24VV2BTR protect both differential and single-ended signals?
Yes - its dual-cathode architecture allows independent clamping of two lines to a shared ground (Pin 3), supporting differential pairs (e.g., RS-485 A/B) and separate single-ended signals (e.g., LIN and wake-up line) without cross-talk or shared impedance paths.
Is the 30 kV ESD rating applicable to both contact and air discharge?
Yes - the ±30 kV rating applies to both IEC 61000-4-2 contact discharge and air discharge testing, confirmed by ten non-repetitive pulses per test condition, with no parameter shift beyond specification limits after stress.
How should the common cathode (Pin 3) be routed on the PCB?
Pin 3 must connect to a low-inductance ground plane using a short, wide trace or multiple vias - ideally within 2 mm of the protected connector - to minimize transient loop inductance and ensure clamping voltage remains ≤33 V during 3.5 A surges.
