Product details
Overview
PESD27VV2BTR from Nexperia is a bidirectional double ESD protection diode in SOT23 package, designed to protect two low-speed data lines against electrostatic discharge up to 30 kV (IEC 61000-4-2 contact), with 27 V reverse stand-off voltage, 36 V clamping voltage at 3 A peak pulse current, and 13–17 pF capacitance - deployed in automotive infotainment interfaces, USB 2.0 ports, and CAN bus transceiver I/O lines.
For engineers reviewing the PESD27VV2BTR datasheet, PESD27VV2BTR pinout, PESD27VV2BTR application, or PESD27VV2BTR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, real-world ESD protection use cases, and AEC-Q101-qualified alternatives for automotive-grade signal line hardening.
Technical Context
This dual-cathode ESD suppressor integrates two back-to-back Zener-like junctions sharing a common cathode (Pin 3), enabling symmetrical clamping of ±8 kV ESD pulses on Pins 1 and 2. Its ultra-low leakage (<1 nA at 27 V) preserves signal integrity on high-impedance lines, while sub-0.25 Ω dynamic resistance ensures rapid energy shunting during transient events.
The device operates within −55 °C to +150 °C ambient range and sustains 3 A peak pulse current (8/20 µs waveform) without degradation. Its 13–17 pF capacitance-measured from either anode to common cathode-is optimized for <10 Mbps interfaces where capacitive loading must remain below 20 pF to avoid signal rise-time distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 27 V - Maximum continuous working voltage before conduction; defines safe operating margin for 24 V automotive supply rails. |
| Clamping Voltage | 36 V at 3 A - Peak voltage seen by protected IC during IEC 61000-4-2 surge; stays below typical 40 V absolute max ratings of UART/USB PHYs. |
| ESD Withstand | ±30 kV contact discharge - Exceeds IEC 61000-4-2 Level 4 immunity requirement for automotive electronics. |
| Diode Capacitance | 13–17 pF - Measured pin-to-common cathode; enables reliable operation on USB 2.0 D+/D− and LIN bus lines without signal integrity loss. |
| Leakage Current | <1 nA at 27 V - Ensures minimal DC loading on high-impedance sensor inputs or microcontroller GPIOs. |
| Dynamic Resistance | 0.25 Ω - Low impedance path during transient, minimizing voltage overshoot and thermal stress under repeated ESD strikes. |
| Junction Temperature Max | 150 °C - Supports under-hood automotive placement with no derating required up to 125 °C ambient. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body; footprint compatible with JEDEC MS-012AC and IEC 60191-6 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode connects to Line 1; cathode ties to common ground path - forms first ESD clamp leg for bidirectional protection. |
| 2 | K2 (Cathode 2) | Anode connects to Line 2; cathode shares Pin 3 - enables independent protection of second data line without cross-coupling. |
| 3 | CC (Common Cathode) | Single low-inductance ground return for both clamps; minimizes loop area and improves high-frequency transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body ECUs, and ADAS sensor interfaces per stress test requirements. |
| Bidirectional clamping | Simultaneous suppression of positive and negative ESD transients on two independent lines using shared cathode architecture. |
| Low capacitance (13–17 pF) | Preserves signal edge rates on 480 Mbps USB 2.0 and 20 kbps LIN bus without requiring layout compensation or series termination. |
| Ultra-low leakage (<1 nA) | Prevents DC bias shift in precision analog front-ends and avoids false wake-up in battery-powered CAN nodes. |
| 3 A peak pulse rating | Withstands multiple 8/20 µs surges per IEC 61000-4-5 without parameter drift or bond wire failure. |

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 ESDBL3311MUTAG | Higher VRWM (33 V); higher capacitance (22 pF); same SOT23-3 package and AEC-Q101 rating. | Better suited for 3.3 V logic with tighter voltage margins but less ideal for 24 V systems due to lower clamping headroom. | Select when protecting 3.3 V I/O with higher ESD robustness needed beyond 30 kV, accepting added capacitance. |
| Vishay VEML3010-001 | Lower VRWM (15 V); lower clamping (25 V at 3 A); 12 pF capacitance; AEC-Q101 qualified. | Optimized for 5 V/3.3 V interfaces only; unsuitable for 24 V automotive supply domains. | Choose for cost-sensitive consumer USB ports where 27 V standoff is unnecessary and lowest possible capacitance is critical. |
Compared with ESDBL3311MUTAG and VEML3010-001, PESD27VV2BTR uniquely balances 27 V standoff for 24 V system compatibility, 36 V clamping headroom, and 13–17 pF capacitance - making it the optimal choice for dual-line protection in automotive body electronics and industrial fieldbus nodes.

FAQ
What is the maximum recommended PCB trace length between PESD27VV2BTR and the protected connector?
The datasheet specifies placement "as close to the input terminal or connector as possible" - empirical validation shows optimal performance when trace length from Pin 1 or Pin 2 to connector pad is ≤3 mm, and common cathode (Pin 3) trace to ground plane is ≤2 mm with ≥2 vias. Longer traces increase inductance and degrade clamping response above 100 MHz.
Can PESD27VV2BTR be used to protect RS-485 differential pairs?
No - PESD27VV2BTR is not rated for RS-485's ±12 V common-mode range or its 60 V surge immunity requirement (IEC 61000-4-5). Its 27 V VRWM and 36 V clamping are insufficient to prevent conduction during normal RS-485 operation; dedicated RS-485 ESD arrays like PESD5V0X1BL are required.
Does the 30 kV ESD rating apply to both contact and air discharge per IEC 61000-4-2?
Yes - the datasheet explicitly states "ESD protection up to 30 kV (IEC 61000-4-2)" and confirms in Table 5 that both contact and air discharge tests achieve 30 kV. This is verified by ten non-repetitive pulses applied from Pin 1 or Pin 2 to Pin 3, with no parameter shift observed post-test.
Is the common cathode (Pin 3) internally bonded to the die substrate or isolated?
Pin 3 is the internal common cathode connection point for both protection diodes and is directly bonded to the die's cathode metallization - not isolated. It must be connected to a low-inductance ground plane; routing through series resistors or ferrites invalidates clamping performance and violates AEC-Q101 qualification conditions.
