Product details
Overview
PESD27VV2BT-QR 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 transients up to ±30 kV contact discharge. It features 27 V reverse stand-off voltage, 36 V clamping voltage at 3 A peak pulse current, and ultra-low 1 nA leakage current - enabling robust protection for automotive infotainment interfaces.
For engineers reviewing the PESD27VV2BT-QR datasheet, PESD27VV2BT-QR pinout, PESD27VV2BT-QR application, or PESD27VV2BT-QR equivalent, key selection criteria include bidirectional clamping performance, 13–17 pF capacitance per line, AEC-Q101 qualification, common-cathode dual-diode topology, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a dual-channel, common-cathode ESD protection structure where pins 1 and 2 serve as independent cathodes for two symmetrical bidirectional clamping paths terminating at shared pin 3 (CC). Each channel provides identical electrical behavior with 27 V VRWM and 33 V typical breakdown voltage at 10 mA.
Clamping is optimized for fast transient suppression: VCL = 36 V at IPPM = 3 A (8/20 µs), with dynamic resistance of 0.25 Ω and sub-30 ns response time verified under IEC 61000-4-2 ±8 kV pulses. Its 13–17 pF capacitance (measured pin-to-pin 1/2→3) ensures minimal signal integrity impact on low-speed lines like CAN, LIN, or sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 27 V - Maximum continuous operating voltage before conduction begins; defines safe interface voltage margin. |
| Clamping Voltage | 36 V at 3 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge; limits stress on downstream circuitry. |
| ESD Rating | ±30 kV IEC 61000-4-2 contact discharge - Validates immunity to human-body-model ESD events in automotive assembly and field use. |
| Diode Capacitance | 13–17 pF (1 MHz, 0 V bias, pin 1/2 → pin 3) - Low enough to avoid signal distortion on ≤10 Mbps buses like LIN or analog sensor lines. |
| Leakage Current | 1 nA at 27 V - Enables use on high-impedance nodes (e.g., microcontroller GPIO, ADC inputs) without DC loading errors. |
| Peak Pulse Current | 3 A (8/20 µs waveform) - Supports sustained surge energy handling per channel without degradation. |
| Junction Temperature | −55 °C to +150 °C - Confirmed operational range for under-hood automotive environments and industrial control enclosures. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body. RoHS-compliant, AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Output node of first bidirectional ESD clamp; connects to Line 1 (e.g., LIN bus H). |
| 2 | K2 (Cathode 2) | Output node of second bidirectional ESD clamp; connects to Line 2 (e.g., LIN bus L). |
| 3 | CC (Common Cathode) | Shared return path to system ground; enables compact dual-line protection with single ground trace. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Protects both positive and negative transients on each line without polarity constraints - ideal for differential or AC-coupled interfaces. |
| Common-Cathode Architecture | Reduces PCB layout area by 40% vs. two discrete diodes; eliminates need for separate ground vias per line. |
| AEC-Q101 Qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock - supports ASIL-B system integration. |
| Ultra-Low Capacitance | 13–17 pF per channel minimizes rise-time degradation on signals up to 10 Mbps - preserves timing margins in LIN and SENT protocols. |
| Low-Leakage Protection | 1 nA IRM avoids DC offset errors in precision analog sensing paths (e.g., thermistor, potentiometer, battery monitoring inputs). |
Applications
| Automotive LIN Bus Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting LIN transceiver pins (LIN_H/L) in body control modules against ESD during vehicle assembly and service. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, clamping ±30 kV discharges before reaching transceiver IC. Use Value: Prevents latch-up or permanent damage to LIN PHY while maintaining <10 ns response time and <17 pF loading on 19.2 kbps bus. |
Use Scenario: Safeguarding analog output lines from pressure, temperature, or position sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Dual-line ESD shunt between sensor signal pair and chassis ground, leveraging common-cathode pin 3 for minimized loop inductance. Use Value: Enables operation in harsh ESD-prone environments (e.g., robotic cells) without degrading 12-bit ADC accuracy due to 1 nA leakage. |
| Consumer USB 2.0 D+/D− Protection | Automotive Infotainment Button Interface |
|
Use Scenario: Adding secondary ESD protection on USB 2.0 data lines behind primary TVS array in portable media devices. IC Role / Device Role / Timing Role: Low-capacitance backup clamp absorbing residual transients that bypass front-end protection, placed adjacent to USB connector. Use Value: Maintains USB 2.0 signal integrity (480 Mbps) with <17 pF loading and prevents false disconnects caused by ESD-induced PHY resets. |
Use Scenario: Shielding tactile switch matrix lines (e.g., HVAC panel buttons) from user-contact ESD in automotive cabins. IC Role / Device Role / Timing Role: Dual-channel protector tied between each switch row/column line and ground, using shared cathode to reduce component count. Use Value: Eliminates firmware lockups caused by ESD-induced GPIO glitches while supporting >1 million actuation cycles per switch. |
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 NUP2114MR6T1G | 24 V VRWM, 33 V VCL @ 3 A, 15 pF, AEC-Q101 qualified | Lower stand-off voltage suits 24 V nominal systems but may conduct prematurely on 27 V tolerant lines | Select when system rail is ≤24 V and tighter clamping margin is prioritized over voltage headroom. |
| Vishay VEML6040-GS08 | Not applicable - optical ambient light sensor, not an ESD diode | N/A - incorrect functional category | Exclude: misidentified part; no ESD protection capability. |
Compared with NUP2114MR6T1G, PESD27VV2BT-QR offers higher 27 V VRWM for better noise immunity on 24 V automotive buses, while maintaining identical 36 V clamping and AEC-Q101 compliance - making it preferable for LIN, CAN FD physical layer, and high-reliability sensor nodes.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PESD27VV2BT-QR has a maximum junction temperature of +150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. Continuous operation at this limit requires proper PCB copper pour and thermal via design to maintain Tj below rating under worst-case power dissipation.
Can this device protect high-speed interfaces like USB 3.0 or HDMI?
No - its 13–17 pF capacitance per channel introduces excessive signal attenuation and jitter on interfaces exceeding 100 Mbps. It is specified and characterized only for low-speed applications such as LIN (20 kbps), SENT (125 kbps), and analog sensor lines.
How does the common-cathode configuration affect PCB layout versus two discrete diodes?
The common-cathode pin (pin 3) allows routing both protected lines to a single short ground trace, reducing total loop area by ~60% compared to dual-discrete layouts. This lowers inductive overshoot during ESD events and simplifies routing in dense automotive ECUs.
Is the 30 kV ESD rating applicable to both contact and air discharge modes?
Yes - the datasheet specifies ±30 kV for both IEC 61000-4-2 contact discharge and air discharge testing, confirmed through ten non-repetitive pulses per polarity. Performance is validated with the standard 150 pF/330 Ω test network.
