Nexperia USA Inc. PESD5V0S1BB,115

Overview

PESD5V0S1BB from Nexperia is a bidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (12 A), with 5 V reverse standoff voltage, 14 V clamping voltage at 12 A, and 35–45 pF capacitance - deployed in high-speed data lines of portable consumer electronics.

For engineers reviewing the PESD5V0S1BB datasheet, PESD5V0S1BB pinout, PESD5V0S1BB application, or PESD5V0S1BB equivalent, key selection criteria include bidirectional clamping capability, ultra-low leakage (5 nA), low capacitance for signal integrity, and compact SOD523 footprint for space-constrained PCB layouts near connectors.

Technical Context

This dual-cathode, bidirectional TVS diode implements a symmetrical back-to-back PN junction configuration across pins 1 and 2, enabling clamping of both positive and negative transients without polarity dependence. It operates within a −55 °C to +150 °C ambient range and supports non-repetitive 8/20 µs surge pulses up to 130 W peak power.

The device achieves ESD robustness via low dynamic impedance (≤50 Ω) and fast response (<1 ns rise time per IEC 61000-4-2), with clamping performance validated at 12 A peak pulse current and thermal stability confirmed up to 150 °C junction temperature.

FAQ

What is the maximum operating temperature for PESD5V0S1BB?

The PESD5V0S1BB has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (R_θJA) is not published, but the SOD523 package supports reliable operation in handheld devices under typical power dissipation conditions during ESD events.

Does PESD5V0S1BB require external biasing or control signals?

No. PESD5V0S1BB is a passive, two-terminal device with no power supply or enable pin. It operates automatically: conducting only during overvoltage transients exceeding its breakdown threshold (~5.5 V), remaining high-impedance (5 nA leakage) during normal 0–5 V signal operation.

Can PESD5V0S1BB be used on differential pairs like HDMI or MIPI?

Yes - but only per individual line (e.g., TMDS clock+ and clock− each require separate PESD5V0S1BB units). Its 35–45 pF capacitance is compatible with HDMI 1.4 (max 100 pF per line) and MIPI D-PHY v1.2 (max 50 pF), provided layout maintains symmetry and minimizes stub length.

How does the L7 marking correlate to pin 1 orientation?

The "L7" laser marking on the SOD523 body aligns with the cathode band, which identifies Pin 1. When viewed from top with marking visible and cathode band at left, Pin 1 is the left terminal and Pin 2 is the right terminal - consistent with SC-79 mechanical drawings and Nexperia's package outline Figure 9.
