Product details
Overview
PESD5V2S2UT from Nexperia is a unidirectional double ESD protection diode in SOT23 package, designed to protect two data or transmission lines against electrostatic discharge. It delivers 30 kV IEC 61000-4-2 contact ESD immunity, clamps at 20 V under 15 A surge, and exhibits 152 pF typical capacitance at 1 MHz - enabling use on high-speed USB 2.0 and parallel port interfaces.
For engineers reviewing the PESD5V2S2UT datasheet, PESD5V2S2UT pinout, PESD5V2S2UT application, or PESD5V2S2UT equivalent, key selection criteria include reverse standoff voltage (5.2 V), clamping voltage at 15 A (20 V), diode capacitance (152–200 pF), peak pulse power (260 W), and SOT23-compatible layout for compact PCB protection.
Technical Context
This dual-cathode, common-anode ESD suppressor operates as two independent unidirectional protection paths between pins 1–3 and 2–3. Its low 80 Ω differential resistance and sub-1 µA reverse leakage at 5.2 V support signal integrity on low-voltage, high-impedance lines.
The device complies with IEC 61000-4-2 Level 4 (±30 kV contact) and IEC 61000-4-5 (15 A, 8/20 µs surge), with clamping performance validated across junction temperatures up to 150 °C and ambient ranges from –65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.2 V - Ensures no conduction during normal 5 V logic operation; defines maximum working voltage before breakdown. |
| Clamping Voltage | 20 V at 15 A - Limits transient voltage seen by downstream ICs during IEC 61000-4-5 surge events. |
| Diode Capacitance | 152–200 pF at 1 MHz - Low enough for USB 2.0 (480 Mbps) and parallel port signaling without signal degradation. |
| Peak Pulse Power | 260 W at 8/20 µs - Sustains high-energy transients without failure per IEC 61000-4-5 compliance. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - Exceeds industrial immunity requirements for connector-level ESD robustness. |
| Breakdown Voltage | 6.4–7.2 V at 5 mA - Confirms reliable turn-on margin above 5.2 V standoff, preventing false triggering. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for reflow and wave soldering per Figures 10–11 in Nexperia's datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line; current flows from line to common anode (pin 3) during overvoltage. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line; enables independent protection of two unidirectional signals sharing ground return. |
| 3 | A (common anode) | Connected to system ground; serves as shared surge return path for both protection channels. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Two independent cathodes (pins 1 & 2) with shared anode (pin 3) enable discrete routing for separate data lines without cross-talk. |
| Low clamping voltage | 20 V at 15 A ensures downstream 5 V logic ICs remain within absolute maximum ratings during surge events. |
| Ultra-low leakage | <150 nA at 5.2 V minimizes standby current draw and avoids loading of high-impedance sensor or analog inputs. |
| High ESD immunity | 30 kV contact discharge rating exceeds IEC 61000-4-2 Level 4, supporting ruggedized industrial and peripheral designs. |
| Controlled capacitance | 152 pF typical allows placement on 480 Mbps USB 2.0 D+/D− lines without measurable eye diagram degradation. |
Applications
| USB 2.0 Interface Protection | Parallel Port ESD Hardening |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of a USB 2.0 host controller against connector-induced ESD. IC Role / Device Role: Unidirectional transient voltage suppressor placed directly at the USB receptacle. Use Value: 152 pF capacitance preserves signal integrity at 480 Mbps; 20 V clamping prevents damage to PHY transceivers rated for 5.5 V absolute max. |
Use Scenario: Shielding bidirectional data bus (D0–D7) and control lines (STROBE, ACK) of a legacy parallel printer port. IC Role / Device Role: Dual-channel clamp limiting transient voltages on two critical signal pairs simultaneously. Use Value: Common-anode architecture reduces component count vs. two discrete diodes; 30 kV ESD rating meets EN 61000-6-2 industrial immunity requirements. |
| Audio Line Input Protection | Industrial Sensor Signal Conditioning |
|
Use Scenario: Safeguarding line-in inputs of consumer audio codecs against handling ESD during cable insertion. IC Role / Device Role: Low-leakage (0.15 µA) clamp preserving DC bias stability of AC-coupled analog inputs. Use Value: Sub-1 µA IR ensures minimal offset shift in high-gain preamp stages; 5.2 V VRWM aligns with 5 V rail-powered audio ICs. |
Use Scenario: Protecting analog output lines (e.g., 4–20 mA transmitter outputs) in PLC I/O modules exposed to field wiring surges. IC Role / Device Role: Surge-rated protector mounted at terminal block entry point, shunting transients to chassis ground. Use Value: 260 W peak pulse power handles IEC 61000-4-5 15 A surges; 150 °C max junction temperature supports operation in enclosed industrial enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Higher VRWM (5.3 V), lower clamping (18 V at 15 A), 120 pF capacitance | Better suited for 5.3 V systems with tighter clamping margin; lower capacitance benefits >1 Gbps interfaces | Select when optimizing for ultra-low capacitance and tighter clamping in 5.3 V domains; verify marking compatibility in automated assembly. |
| TPD2E001DRYR | Bi-directional configuration, 10 pF capacitance, 12 V clamping at 1 A (not rated at 15 A) | Designed for low-capacitance USB Type-C CC lines; lacks IEC 61000-4-5 surge rating | Choose only for low-voltage, low-energy signal lines where bi-directional protection and <15 pF are mandatory; not suitable for 15 A surge environments. |
Compared with ESD5V3U2U-2/TR and TPD2E001DRYR, PESD5V2S2UT offers balanced trade-offs: verified 15 A surge capability, 30 kV ESD rating, and 152 pF capacitance - making it optimal for cost-sensitive, industrial-grade USB 2.0 and parallel port protection where robustness outweighs ultra-low capacitance needs.

FAQ
What is the maximum operating temperature for PESD5V2S2UT?
The PESD5V2S2UT has a maximum junction temperature of 150 °C and an ambient operating range from –65 °C to +150 °C. Thermal derating follows Figure 4 in the datasheet: peak pulse power drops to ~80% at 100 °C junction temperature, requiring layout attention for sustained surge conditions.
Can PESD5V2S2UT protect bidirectional data lines like RS-232 or CAN?
No - PESD5V2S2UT is unidirectional only, with cathodes on pins 1 and 2 and a common anode on pin 3. It cannot clamp negative transients on lines referenced to ground. For bidirectional protection, a dedicated bi-directional device such as PESD5V0S1BA must be used instead.
How should PESD5V2S2UT be laid out on a PCB for optimal ESD performance?
Place PESD5V2S2UT within 2 mm of the protected connector, route protected traces directly to pins 1 and 2 with minimum stub length, connect pin 3 to a low-inductance ground plane via multiple vias, and avoid routing unprotected signals adjacent to protected ones - per guidelines in Section 10 of the Nexperia datasheet.
Is PESD5V2S2UT qualified for automotive applications?
No - the April 2023 datasheet explicitly states this part is non-automotive qualified (Revision History, Section 13). It lacks AEC-Q200 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends the PESD5V2S2UT-Q variant or other Q-qualified members of the PESDXS2UT series.
