Product details
Overview
PESD5V0X1BT from Nexperia is an ultra-low-capacitance bidirectional ESD protection diode in SOT23 package, designed to protect one high-speed signal line (e.g., USB 2.0 or RF antenna trace) against IEC 61000-4-2 level 4 ESD events up to ±9 kV, with 0.9 pF typical capacitance at 0 V, 5 V reverse standoff voltage, and 1 nA leakage current at 5 V.
For engineers reviewing the PESD5V0X1BT datasheet, PESD5V0X1BT pinout, PESD5V0X1BT application, or PESD5V0X1BT equivalent, this device is selected for high-frequency signal integrity preservation in USB, Ethernet, SIM card, and RF front-end protection where sub-1 pF capacitance and low clamping voltage are critical.
Technical Context
This dual-cathode, common-anode ESD diode supports two distinct configurations: bidirectional protection across pins 1–2 (for AC-coupled or bipolar signal lines), and unidirectional protection across pins 1–3 or 2–3 (for two independent positive-only signal paths). Its symmetrical V-I characteristics enable robust clamping under both polarities of transient stress.
The device operates within −55 °C to +150 °C ambient range, features 100 Ω differential resistance at 1 mA, and maintains stable capacitance (<1.3 pF) up to 5 V reverse bias-enabling minimal signal distortion on 10/100/1000 Mbit/s Ethernet and high-speed data interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction; ensures no interference with 3.3 V or 5 V logic signaling. |
| Diode Capacitance (bidir) | 0.9 pF (typ.) at 1 MHz, 0 V - Preserves signal integrity on >500 MHz RF traces and USB 2.0 differential pairs. |
| ESD Withstand (IEC 61000-4-2) | ±9 kV contact discharge - Meets industrial and consumer end-equipment immunity requirements without external circuitry. |
| Reverse Leakage Current | 1 nA (typ.) at 5 V - Prevents DC loading on sensitive analog or RF bias networks. |
| Breakdown Voltage | 7.5 V (typ.) at 5 mA - Defines onset of clamping; enables safe margin above 5 V VRWM for transient suppression. |
| Differential Resistance | 100 Ω (max.) at 1 mA - Limits voltage overshoot during fast transients, supporting low-clamp performance. |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected signal line in bidirectional mode or first unidirectional line; forms low-impedance path to common anode during ESD event. |
| 2 | K2 (cathode of diode 2) | Connects to second protected signal line in unidirectional mode or same line as K1 in bidirectional configuration; enables dual-line or single-line protection flexibility. |
| 3 | CA (common anode) | Ground reference terminal; must be connected directly to low-inductance system ground plane to ensure effective transient shunting and minimal clamping voltage rise. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional single-line protection | Enables ESD hardening of AC-coupled or differential signals (e.g., USB D+/D−) without polarity constraints. |
| Unidirectional dual-line capability | Allows protection of two independent positive-rail signal paths (e.g., SIM CLK & SIM I/O) using one device and shared ground return. |
| 0.9 pF typical capacitance | Minimizes insertion loss and phase distortion on 480 Mbps USB 2.0 and 1 Gbps Ethernet channels. |
| 1 nA max reverse leakage | Prevents signal degradation in high-impedance RF detector or antenna tuning circuits. |
| IEC 61000-4-2 level 4 compliance | Validated for ±9 kV contact discharge-meets EN 61000-6-2 and FCC Part 15 Class B immunity requirements. |
Applications
| USB 2.0 Interface Protection | RF Antenna Front-End Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (3.5 pF typ.), higher leakage (50 nA), but rated for ±15 kV ESD. | Better suited for lower-speed interfaces (e.g., UART, I²C) where clamping robustness outweighs capacitance sensitivity. | Select when ESD threat exceeds ±9 kV and signal bandwidth <100 MHz. |
| Vishay VEML6030X01 | Not applicable - optical sensor, not ESD diode; excluded from valid alternatives. | N/A | Not a functional alternative; omitted due to incorrect device category. |
Compared with NUP4105MR6T1G, PESD5V0X1BT delivers superior high-frequency performance (0.9 pF vs. 3.5 pF) and lower leakage (1 nA vs. 50 nA), making it optimal for USB 2.0, RF, and Gigabit Ethernet; NUP4105MR6T1G trades capacitance for higher ESD rating in cost-sensitive, lower-bandwidth applications.

FAQ
What is the maximum operating temperature for PESD5V0X1BT?
The PESD5V0X1BT supports operation from −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. This range accommodates deployment in automotive under-hood modules, industrial gateways, and handheld devices with internal thermal dissipation constraints.
Can PESD5V0X1BT protect two independent signal lines simultaneously?
Yes-when used in unidirectional configuration, pins 1–3 and 2–3 each form independent ESD protection paths to the common anode (pin 3), enabling simultaneous safeguarding of two positive-rail signals such as SIM CLK and SIM I/O, provided both share the same ground reference.
How does PESD5V0X1BT's capacitance vary with applied voltage?
Capacitance remains stable at 0.9 pF (typ.) from 0 V to 5 V reverse bias in bidirectional mode; in unidirectional mode, it rises to 1.7–2.3 pF over the same range. This behavior is documented in Figures 2 and 3 of the official Nexperia datasheet v.3 (April 2023).
Is PESD5V0X1BT qualified for automotive applications?
No-per Revision History section 13, PESD5V0X1BT was changed to non-automotive qualification in v.3 (April 2023). For automotive use, Nexperia offers the PESD5V0X1BQ variant, which undergoes AEC-Q101 stress testing and is explicitly designated for automotive-grade systems.
