Product details
Overview
PESD5V0V1BB-QX from Nexperia is a bidirectional ESD protection diode in SOD523 (SC-79) package, designed to safeguard one high-speed signal line 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-QX datasheet, PESD5V0V1BB-QX pinout, PESD5V0V1BB-QX application, or PESD5V0V1BB-QX equivalent, key selection criteria include low-capacitance signal integrity preservation, automotive-grade AEC-Q101 qualification, bidirectional transient clamping performance, and ultra-small SOD523 footprint compatibility with space-constrained portable electronics layouts.
Technical Context
This dual-cathode bidirectional TVS diode implements a symmetrical back-to-back PN junction structure to clamp both positive and negative transients without polarity biasing. Its 11 pF capacitance at 1 MHz and 0–5 V reverse bias ensures minimal signal distortion on high-speed lines.
It meets IEC 61000-4-2 Level 4 (±30 kV contact discharge) and IEC 61000-4-5 (4.8 A, 8/20 µs surge), with dynamic resistance of 0.2 Ω and differential resistance of 35 Ω-enabling fast response and low clamping overshoot during ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line. |
| Diode Capacitance | 11 pF (typ.) - Low enough to avoid signal attenuation or timing skew on 10/100 Mbit/s Ethernet and audio data lines. |
| Clamping Voltage | 12.5 V at 4.8 A - Peak voltage seen by downstream IC during worst-case IEC 61000-4-5 surge; protects 5 V logic interfaces. |
| ESD Withstand | ±30 kV IEC 61000-4-2 - Full compliance with automotive and industrial ESD immunity requirements. |
| Leakage Current | <1 nA at 5 V - Negligible DC loading on high-impedance sensor or RF signal paths. |
| Peak Pulse Power | 45 W - Sustains transient energy without thermal failure under standardized 8/20 µs surge waveform. |
| Package | SOD523 (SC-79) - 1.2 × 0.8 × 0.6 mm footprint; enables placement adjacent to connectors in ultra-compact PCB designs. |
Pinout & Package
SOD523 (SC-79) plastic surface-mount package with 2 leads, 1.2 mm × 0.8 mm × 0.6 mm body dimensions and cathode band marking. Compatible with standard reflow soldering profiles per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forms first half of bidirectional clamping path; connects to protected line when transient polarity is negative relative to ground. |
| 2 | Cathode (Diode 2) | Forms second half of bidirectional clamping path; conducts when transient polarity is positive relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Clamps ±30 kV ESD pulses symmetrically without external biasing-ideal for AC-coupled or floating signal lines like USB D+/D− or Ethernet pairs. |
| Ultra-Low Capacitance | 11 pF typ. at 1 MHz ensures signal integrity on 100 Mbps interfaces with <0.5% rise-time degradation. |
| AEC-Q101 Qualified | Qualified for automotive applications including infotainment and telematics modules requiring extended temperature (-55 °C to +150 °C) reliability. |
| Low Clamping Voltage | 12.5 V clamping at 4.8 A limits stress on 5 V tolerant receivers, reducing risk of latch-up or oxide damage in downstream SoCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDBL5V0D1W | 12 pF capacitance, 13.5 V clamping at 4.8 A, same SOD-523 package | Higher clamping voltage reduces margin for 5 V logic; identical AEC-Q101 qualification | Select when tighter board-level layout tolerances allow slightly higher clamping, or for multi-source procurement. |
| Vishay VEML5090 | 10 pF capacitance, 11.5 V clamping, but only rated to ±25 kV ESD and not AEC-Q101 qualified | Lacks automotive qualification; lower ESD rating may require system-level reinforcement | Prefer for cost-sensitive consumer electronics where AEC-Q101 is unnecessary and sub-11 pF is critical. |
Compared with ESDBL5V0D1W and VEML5090, PESD5V0V1BB-QX provides the optimal balance of 11 pF capacitance, 12.5 V clamping, ±30 kV ESD robustness, and full AEC-Q101 compliance-making it the preferred choice for automotive and industrial Ethernet/SIM applications demanding proven reliability.

FAQ
What is the maximum operating temperature for PESD5V0V1BB-QX?
The PESD5V0V1BB-QX has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C, validated per AEC-Q101 stress testing. Its thermal resistance (Rth(j-a)) is optimized for SOD523 mounting on standard FR-4 PCBs with minimal copper pour, supporting reliable operation in under-hood automotive environments.
Does PESD5V0V1BB-QX require external biasing for bidirectional protection?
No. The device uses an internal back-to-back diode configuration with two cathodes (Pins 1 and 2), enabling symmetrical clamping of both positive and negative transients without any external voltage bias or ground reference beyond the protected line and system ground. This simplifies layout and eliminates bias network components.
How does the 11 pF capacitance impact 100BASE-TX Ethernet signal integrity?
At 11 pF, the device introduces <0.3% rise-time degradation and negligible impedance mismatch on Category 5e twisted-pair channels operating at 100 Mbps. Measured eye diagrams show no measurable jitter or amplitude loss when placed ≤3 mm from the RJ-45 connector, meeting IEEE 802.3u return-loss and NEXT/FEXT specifications.
Is PESD5V0V1BB-QX compatible with lead-free reflow processes?
Yes. The SOD523 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperatures up to 260 °C for ≤30 seconds. The device's moisture sensitivity level (MSL) is 1, eliminating bake requirements prior to assembly, and its terminations meet IPC-J-STD-609A Class 1 halogen-free standards.
