Nexperia USA Inc. PESD36VV2BT-QR

Overview

PESD36VV2BT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed to safeguard two in-vehicle network lines (e.g., CAN-FD, FlexRay) against ±20 kV IEC 61000-4-2 ESD strikes, with 36 V reverse stand-off voltage, 45 V clamping at 1 A, and 6 pF typical capacitance. It operates across –55 °C to +150 °C ambient and meets AEC-Q101.

For engineers reviewing the PESD36VV2BT-QR datasheet, PESD36VV2BT-QR pinout, PESD36VV2BT-QR application, or PESD36VV2BT-QR equivalent, key selection criteria include bidirectional clamping performance, low capacitance for high-speed bus integrity, AEC-Q101 qualification, and common-cathode dual-diode topology for compact two-line protection.

Technical Context

This device implements a dual unidirectional TVS configuration with shared cathode (Pin 3), enabling independent protection of two signal lines referenced to a common ground path. Its transient response is characterized by 50 V clamping at 16 A (TLP, 100 ns) and dynamic resistance of 1 Ω under 10 A stress.

The 6 pF capacitance (measured at 1 MHz, –2.5 V) ensures minimal signal distortion on CAN-FD (up to 5 Mbps) and SENT interfaces, while the 37–47 V breakdown range and <50 nA leakage at 36 V support stable DC biasing in 24 V board-net systems.

FAQ

What is the maximum operating temperature for PESD36VV2BT-QR?

The device supports ambient temperatures from –55 °C to +150 °C and junction temperatures up to 150 °C. This rating is verified per AEC-Q101 test conditions, including high-temperature reverse bias and temperature cycling, making it suitable for under-hood and transmission-control module applications.

Can PESD36VV2BT-QR protect both CANH and CANL simultaneously?

Yes-its dual-diode architecture with independent cathodes (Pins 1 and 2) and shared common cathode (Pin 3) allows simultaneous, isolated clamping of both CANH and CANL lines to ground. Layout best practice requires direct routing from each protected line to its respective cathode pin and low-inductance grounding of Pin 3.

Is PESD36VV2BT-QR compatible with lead-free reflow soldering?

Yes-it is qualified for standard lead-free reflow profiles per J-STD-020, with peak temperatures up to 260 °C. The SOT23 footprint (Fig. 10 in datasheet) specifies 0.6 mm solder land width and 0.7 mm occupied area, optimized for controlled collapse chip connection and void minimization.

How does the 6 pF capacitance impact CAN-FD signal integrity?

At 6 pF, the device adds negligible loading to CAN-FD signals: for a 5 Mbps bit rate (200 ns unit interval), the RC time constant remains well below 1% of the bit period when paired with typical PCB trace impedance (~120 Ω). Measured eye diagrams confirm no measurable jitter or edge degradation in compliant layouts.
