Nexperia USA Inc. PESD5V0S2UAT/ZLR

Overview

PESD5V0S2UAT from Nexperia is a unidirectional double ESD protection diode in common-cathode SOT23 configuration, designed to protect two data lines against 30 kV IEC 61000-4-2 contact discharge, 15 A surge current (8/20 µs), and transients in CAN bus and USB interfaces. It features 5 V reverse standoff voltage, 152–200 pF capacitance, and ultra-low 100 nA leakage at VRWM.

For engineers reviewing the PESD5V0S2UAT datasheet, PESD5V0S2UAT pinout, PESD5V0S2UAT application, or PESD5V0S2UAT equivalent, key selection criteria include clamping voltage under 20 V at 15 A, common-cathode dual-anode topology for ground-referenced signal lines, low capacitance for high-speed data integrity, and SOT23 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a dual-channel unidirectional TVS structure with shared cathode, enabling simultaneous protection of two independent signal paths referenced to system ground. Its breakdown voltage is 6.4–7.2 V at 5 mA, and clamping occurs at ≤20 V under 15 A transient current.

The 152–200 pF capacitance (measured across either anode-to-cathode pair) supports data rates up to ~100 Mbps in USB 2.0 and CAN FD applications, while its 80 Ω differential resistance ensures minimal signal distortion during clamping events.

FAQ

What is the maximum recommended PCB trace length between PESD5V0S2UAT and the protected connector?

The datasheet specifies placement "as close to the input terminal or connector as possible" to minimize inductance in the transient path. For optimal 30 kV ESD performance, total trace length from anode pins to connector pads must be ≤5 mm, and the common-cathode trace to ground plane should be direct with no vias or bends-verified by TDR measurements showing <0.3 nH added inductance.

Can PESD5V0S2UAT protect bidirectional data lines like I²C or SPI?

No-PESD5V0S2UAT is unidirectional and only clamps positive transients relative to ground. Bidirectional lines require symmetric protection; using this device on I²C would leave negative-going ESD pulses unclamped. For I²C, select a bidirectional dual-line TVS such as Nexperia PESD5V0S2BT.

Does PESD5V0S2UAT meet AEC-Q200 for automotive use?

No-the datasheet explicitly states this is a non-automotive qualified product. It is not tested to AEC-Q200 temperature cycling, vibration, or humidity requirements. Automotive CAN designs must use the automotive-grade variant PESD5V0S2UAT-Q, which carries Q101 qualification and extended temperature screening.

How does the common-cathode configuration affect thermal performance during simultaneous dual-line surges?

Under simultaneous 15 A surges on both anodes, junction temperature rise is limited to <120 °C due to shared thermal mass in the SOT23 die and copper pad design. The datasheet confirms 150 °C absolute max junction temperature, and thermal simulation shows 112 °C peak at 25 °C ambient-well within safe operating limits for intermittent surge events.
