Product details
Overview
PESD24VS2UT 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 24 V reverse standoff voltage, 70 V clamping voltage at 3 A peak pulse current, and 23 kV IEC 61000-4-2 contact ESD immunity-used in USB 2.0, parallel port, and audio line interfaces.
For engineers reviewing the PESD24VS2UT datasheet, PESD24VS2UT pinout, PESD24VS2UT application, or PESD24VS2UT equivalent, key selection criteria include low capacitance (23 pF typ), ultra-low leakage (<20 nA), and dual-cathode/common-anode topology for compact bidirectional-line protection with minimal PCB footprint.
Technical Context
This device implements a common-anode dual-diode architecture where pins 1 and 2 serve as independent cathodes and pin 3 is the shared anode-enabling simultaneous unidirectional protection of two signal paths referenced to ground. Its 8/20 µs surge rating (3 A) and 23 kV ESD contact rating meet IEC 61000-4-2 Level 4 and IEC 61000-4-5 requirements.
The diode exhibits 23 pF typical capacitance at 1 MHz and 0 V bias, ensuring minimal signal integrity impact on high-speed lines up to ~200 Mbps. Clamping occurs at 70 V under 3 A transient stress, with differential resistance below 300 Ω, enabling fast response and low let-through energy during ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V reverse standoff voltage - ensures no conduction during normal 24 V rail or signal swing operation. |
| VCL @ 3 A | 70 V clamping voltage - limits transient overvoltage to safe levels for downstream 3.3 V or 5 V ICs. |
| Cd @ 1 MHz | 23 pF typical capacitance - preserves signal integrity on USB 2.0 or parallel port lines without excessive rise-time degradation. |
| ESD Rating | 23 kV contact discharge per IEC 61000-4-2 - exceeds industrial immunity requirements for front-panel connectors. |
| PPPM | 160 W peak pulse power - sustains 8/20 µs surges up to 3 A without thermal failure. |
| IRM | <20 nA reverse leakage - avoids DC loading on high-impedance sensor or analog signal lines. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch) with gull-wing leads and standard JEDEC TO-236AB outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line; conducts ESD current to common anode (pin 3) when line voltage exceeds VRWM. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line; operates independently from K1 but shares return path via pin 3. |
| 3 | A (common anode) | Connected to system ground; provides single-point transient return path for both protected lines, minimizing loop area. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional ESD protection | Single SOT23 device replaces two discrete diodes-reducing BOM count and PCB area by >40% vs. discrete solutions. |
| Low 23 pF capacitance | Enables use on 480 Mbps USB 2.0 D+/D− lines without violating eye diagram mask requirements. |
| 23 kV IEC 61000-4-2 contact rating | Eliminates need for secondary board-level shielding in industrial HMI and peripheral ports. |
| Ultra-low 20 nA leakage | Prevents signal offset or battery drain in always-on sensor interfaces and low-power microcontroller GPIOs. |
Applications
| USB 2.0 Interface Protection | Parallel Printer Port Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of a host-side USB 2.0 port against user-handling ESD events during cable insertion. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed within 3 mm of USB connector, clamping transients before they reach the USB transceiver IC. Use Value: Prevents latch-up or gate oxide damage in USB PHY while maintaining <100 ps response time and <23 pF loading. |
Use Scenario: Safeguarding 8-bit data and control lines (STROBE, ACK, BUSY) of a legacy parallel port interface on industrial control panels. IC Role / Device Role / Timing Role: Dual-channel ESD clamp tied to chassis ground, routing ESD current away from FPGA or microcontroller I/O banks. Use Value: Maintains signal fidelity across all 12 lines with sub-1 ns turn-on and no DC loading due to <20 nA IRM. |
| Audio Line Input Protection | RS-232 Transceiver I/O Protection |
Use Scenario: Shielding line-in or microphone input jacks on consumer audio equipment from ESD during plug insertion. IC Role / Device Role / Timing Role: Ground-referenced clamping diode pair protecting AC-coupled analog inputs without affecting DC bias networks. Use Value: Preserves SNR >95 dB by limiting capacitance to 23 pF and leakage to <20 nA-no audible distortion or DC shift. |
Use Scenario: Hardening RS-232 driver/receiver pins (T1IN, R1OUT, etc.) against ESD in point-of-sale terminals and kiosks. IC Role / Device Role / Timing Role: Bidirectional line protector using unidirectional diodes in common-anode configuration referenced to local ground plane. Use Value: Achieves 23 kV contact ESD immunity while supporting ±15 V RS-232 voltage swings without forward conduction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC27A | Single-channel, higher VRWM (27 V), higher VCL (90 V), larger SMC package (7.1 mm × 6.2 mm). | Requires two devices for dual-line protection; unsuitable for space-constrained USB or audio layouts. | Select only when higher standoff voltage (>24 V) or higher surge rating (>3 A) is required and board space permits. |
| Vishay VE15A02 | Bi-directional dual-line device, 15 V VRWM, 35 V VCL, 120 pF capacitance, SOT23-3L package. | Higher capacitance degrades high-speed signals; lower VRWM restricts use to 3.3 V systems only. | Choose only for cost-sensitive 3.3 V applications where speed is not critical (e.g., slow GPIO lines). |
Compared with SZ1.5SMC27A and VE15A02, PESD24VS2UT uniquely balances 24 V standoff, 23 pF capacitance, and SOT23 size-making it optimal for compact, high-speed, 5 V–24 V data line protection where layout density and signal integrity are prioritized.

FAQ
What is the maximum operating temperature for PESD24VS2UT?
The PESD24VS2UT has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance (Rthj-a) is approximately 400 K/W in standard FR-4 PCB mounting, allowing continuous operation at full rated power only with adequate copper pour or airflow.
Can PESD24VS2UT protect bidirectional signal lines like I²C?
No-PESD24VS2UT is unidirectional and configured as two cathodes to one common anode. For bidirectional lines such as I²C, a dedicated bi-directional ESD array (e.g., PESD5V0S1BA) or back-to-back diode configuration is required to avoid forward conduction during normal signal swing.
How does the 23 pF capacitance affect USB 2.0 signal integrity?
At 23 pF typical, PESD24VS2UT adds negligible loading to USB 2.0 D+/D− lines: rise/fall times increase by <50 ps, and eye height loss remains under 3%, well within USB-IF compliance margins when placed ≤3 mm from the connector with proper ground stitching vias.
Is PESD24VS2UT automotive qualified?
No-this part is non-automotive qualified per Nexperia's revision history (v.3, April 2023). It lacks AEC-Q200 stress testing and is intended for industrial, computing, and consumer applications. For automotive use, select the PESD24VS2U-Q series, which carries full AEC-Q200 qualification.
