Product details
Overview
PESD24VS5UD,115 from Nexperia is a five-channel unidirectional ESD protection diode array in SOT457 (SC-74) package, designed to protect signal lines with 24 V reverse standoff voltage, 23 kV IEC 61000-4-2 contact ESD rating, 45–70 pF diode capacitance at 1 MHz, and clamping voltage of 52 V at 4 A surge current. It is deployed in SIM card interfaces, high-speed data lines, and portable electronics where low capacitance and robust transient suppression are critical.
For engineers reviewing the PESD24VS5UD,115 datasheet, PESD24VS5UD,115 pinout, PESD24VS5UD,115 application, or PESD24VS5UD,115 equivalent, key selection criteria include per-line 24 V VRWM, sub-70 pF capacitance for signal integrity, 52 V clamping at 4 A IPP, ultra-low 50 pA leakage, and compatibility with IEC 61000-4-2 Level 4 and IEC 61000-4-5 surge standards.
Technical Context
This device implements five independent unidirectional TVS diodes sharing a common anode (Pin 2), enabling compact protection of five separate signal paths against ESD and surge transients. Its architecture supports both positive- and negative-polarity signals relative to ground without requiring bidirectional devices.
Each channel features a silicon avalanche structure optimized for fast response (<1 ns rise time), low clamping voltage under high-current stress (52 V at 4 A), and stable leakage performance (≤15 nA at 24 V, 25 °C). The 8/20 µs surge waveform compliance and 200 W peak pulse power rating per line confirm its suitability for industrial-grade interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous operating voltage before conduction; ensures no interference with 24 V logic or analog signal rails. |
| VCL @ IPP = 4 A | 52 V - Clamped voltage during 8/20 µs surge; limits downstream IC stress to safe levels for 24 V systems. |
| Cd @ 1 MHz, 0 V | 45–70 pF - Low capacitance preserves signal integrity on high-speed lines (e.g., USB 2.0, SIM I/O). |
| VESD (IEC 61000-4-2) | 23 kV contact - Highest ESD immunity in the PESDxS5UD series for demanding handheld environments. |
| IRM @ VRWM = 24 V | 0.05–15 nA - Ultra-low leakage prevents battery drain and signal offset in always-on portable circuits. |
| IPP (max) | 4 A - Peak surge current handling per diode; defines maximum transient energy absorption capability. |
| PPP (8/20 µs) | 200 W - Peak pulse power per channel; enables robust protection against lightning-induced surges. |
Pinout & Package
SOT457 (SC-74) is a 6-pin surface-mount plastic package measuring 3.1 × 1.7 × 1.3 mm, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Channel 1) | Protected signal input/output node for first line; connects to trace requiring ESD suppression. |
| 2 | Common Anode | Shared return path to system ground or bias rail; must be routed with minimal inductance. |
| 3 | Cathode (Channel 2) | Second protected signal line; electrically isolated from other cathodes but shares anode reference. |
| 4 | Cathode (Channel 3) | Third independent protection channel; supports multi-line interfaces like SIM card data buses. |
| 5 | Cathode (Channel 4) | Fourth protected line; enables full coverage of 4-wire serial interfaces or parallel control signals. |
| 6 | Cathode (Channel 5) | Fifth channel cathode; allows simultaneous protection of all five lines in compact space-constrained designs. |
Key Features
| Feature | Design Value |
|---|---|
| Five-channel unidirectional protection | Enables single-device safeguarding of up to five independent signal lines-reducing BOM count and board area vs. discrete diodes. |
| 23 kV IEC 61000-4-2 contact ESD rating | Exceeds Level 4 requirements and exceeds lower-voltage variants in the same family for enhanced ruggedness in handheld applications. |
| 45–70 pF capacitance per channel | Minimizes signal distortion and timing skew on high-frequency lines such as SIM clock/data, UART, or GPIO. |
| Common anode configuration | Simplifies PCB routing by consolidating one return path; avoids ground loop issues when protecting multiple grounded-referenced signals. |
| Ultra-low 50 pA typical IRM | Prevents measurable leakage current in battery-powered devices, extending operational life in always-on SIM or sensor interfaces. |
Applications
| Subscriber Identity Module (SIM) Card Interface | Industrial Serial Communication Port |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDR05V52D | 5 V VRWM, 12 V clamping at 1 A, 100 pF capacitance - lower voltage rating and higher capacitance than PESD24VS5UD,115. | Targeted at 3.3–5 V logic; unsuitable for 24 V signal rails or high-speed lines requiring sub-70 pF loading. | Select only for low-voltage digital interfaces where 24 V standoff is unnecessary and higher capacitance is acceptable. |
| TPD4E05U06DQAR | 5.5 V VRWM, 14 V clamping at 1 A, 0.5 pF typical Cd - much lower capacitance but incompatible with 24 V operation. | Optimized for USB 3.0/PCIe; lacks surge rating and voltage headroom for industrial 24 V signal protection. | Choose for ultra-high-speed (>5 Gbps) applications where capacitance dominates design priority, not voltage or surge robustness. |
Compared with ESDR05V52D and TPD4E05U06DQAR, PESD24VS5UD,115 uniquely balances 24 V standoff, 23 kV ESD immunity, and sub-70 pF capacitance-making it the only option among the three suitable for ruggedized 24 V signal protection in portable and industrial equipment.

FAQ
What is the maximum operating temperature for PESD24VS5UD,115?
The junction temperature limit is 150 °C, and ambient operating range spans −65 °C to +150 °C. This wide thermal envelope supports deployment in automotive engine bays, industrial enclosures, and sealed medical housings without derating under normal conditions.
Can PESD24VS5UD,115 protect bidirectional signal lines?
No-it is a unidirectional diode array with a common anode configuration, intended for signals referenced to ground with defined polarity. For bidirectional lines like USB D+/D−, a dedicated bidirectional array (e.g., PESD5V0S5UD) or dual-rail design is required.
How does the 23 kV ESD rating compare to other parts in the PESDxS5UD series?
PESD24VS5UD,115 has the lowest ESD rating (23 kV contact) in the series due to its higher breakdown voltage (25.5–29 V); lower-voltage variants (e.g., PESD5V0S5UD) achieve 30 kV by virtue of faster avalanche triggering at lower voltages.
Is the common anode (Pin 2) internally connected to ground or left floating?
Pin 2 is the common anode terminal and must be externally connected-to system ground for standard protection, or to a positive bias rail if used in negative-rail protection schemes. It is not internally tied to any potential and requires deliberate PCB routing.
