Nexperia USA Inc. PESD5V0V1BB,115

Overview

PESD5V0V1BB from Nexperia is a bidirectional ESD protection diode in SOD523 (SC-79) package, designed to safeguard single high-speed signal lines against ±30 kV IEC 61000-4-2 ESD events and 4.8 A surge transients. It delivers 11 pF typical capacitance, 12.5 V clamping voltage at 4.8 A, and <1 nA leakage at 5 V, enabling use in 10/100 Mbit/s Ethernet and SIM card interfaces.

For engineers reviewing the PESD5V0V1BB datasheet, PESD5V0V1BB pinout, PESD5V0V1BB application, or PESD5V0V1BB equivalent, key selection criteria include low-capacitance line protection, bidirectional clamping symmetry, IEC 61000-4-2 Level 4 compliance, and ultra-small SOD523 footprint for space-constrained portable electronics layouts.

Technical Context

This dual-cathode bidirectional TVS diode integrates two anti-parallel silicon avalanche structures in one SOD523 package, enabling symmetrical clamping for AC-coupled or bipolar signal lines without polarity constraints. Its layout supports direct placement at I/O connectors with minimal trace inductance.

The device operates within a -55 °C to 150 °C ambient range, maintains <1 nA reverse leakage up to 5 V standoff, and achieves 12.5 V clamping under 4.8 A 8/20 µs surge pulses-meeting IEC 61000-4-5 requirements while preserving signal integrity on high-frequency data paths.

FAQ

What is the maximum working voltage this diode can protect?

The PESD5V0V1BB has a reverse standoff voltage (VRWM) of 5 V, meaning it remains non-conductive up to 5 V DC or peak AC signal voltage. This makes it suitable for protecting 3.3 V and 5 V logic interfaces, including USB 2.0, SIM cards, and Ethernet PHYs, without leakage or false triggering during normal operation.

How does its 11 pF capacitance impact high-speed signal integrity?

At 11 pF typical, the PESD5V0V1BB introduces negligible capacitive loading on 10/100 Mbit/s Ethernet and USB 2.0 signals-preserving rise/fall times, eye opening, and jitter margins. Measurement data confirms no measurable signal degradation up to 100 Mbps, verified via TDR and eye diagram testing per IEEE 802.3 and USB-IF standards.

Can it replace unidirectional ESD diodes in existing designs?

No-PESD5V0V1BB is strictly bidirectional and must be connected between signal and ground with no polarity orientation required. Unidirectional diodes require anode-to-ground or cathode-to-ground configuration and cannot substitute without circuit redesign, as their clamping behavior is asymmetric and incompatible with AC-coupled or floating lines.

Is this device qualified for automotive applications?

No-PESD5V0V1BB is not AEC-Q200 qualified and lacks automotive-specific validation (e.g., extended temperature cycling, humidity testing). Nexperia explicitly states non-automotive qualification in its legal disclaimers; for automotive infotainment or telematics, select AEC-Q200-rated alternatives such as PESD5V0S1BA or Automotive-grade equivalents.
