Product details
Overview
PESD24VL1BA,145 from Nexperia is a unidirectional ESD protection diode array designed for I/O line protection in portable electronics. It features 24 V working voltage, 15 kV contact ESD immunity per IEC 61000-4-2, 0.9 pF typical capacitance, and low clamping voltage of 44 V at 1 A, deployed in USB 2.0 data lines and HDMI interfaces.
For engineers reviewing the PESD24VL1BA,145 datasheet, PESD24VL1BA,145 pinout, PESD24VL1BA,145 application, or PESD24VL1BA,145 equivalent, key selection criteria include clamping performance under fast transient stress, signal integrity impact from junction capacitance, DC blocking capability, and compatibility with high-speed differential interfaces requiring sub-1 pF loading.
Technical Context
This device integrates two back-to-back configured unidirectional ESD protection diodes in a single SOD323 package, enabling bidirectional transient suppression on a single line pair. Its low leakage current (<10 nA at 24 V) ensures minimal impact on bias-sensitive analog or digital receivers.
The diode structure uses planar silicon technology with optimized junction geometry to achieve tight parameter distribution across temperature (−40 °C to +125 °C) and maintain stable clamping behavior during repetitive 8/20 µs surge events up to 12 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 24 V - Maximum continuous DC or RMS signal voltage the device blocks without conduction. |
| ESD Withstand (IEC 61000-4-2) | ±15 kV contact - Survives direct electrostatic discharge events at system-level ESD test severity. |
| Junction Capacitance | 0.9 pF @ 0 V - Minimal signal distortion and insertion loss on 480 Mbps USB 2.0 channels. |
| Clamping Voltage | 44 V @ 1 A - Limits transient overvoltage to safe levels for downstream 3.3 V or 5 V interface ICs. |
| Leakage Current | 5 nA @ 24 V - Prevents DC offset drift and battery drain in always-on sensor or communication ports. |
| Package | SOD323 - 2.1 mm × 1.35 mm footprint compatible with fine-pitch PCB assembly and automated optical inspection. |
Pinout & Package
SOD323 surface-mount package with gull-wing leads; moisture sensitivity level MSL3 per J-STD-020; RoHS-compliant, halogen-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input protection node for Line A | Connected to protected signal line; conducts transient current to ground when voltage exceeds breakdown threshold. |
| Cathode (Pin 2) | Common ground reference | Shared cathode ties both diodes to PCB ground plane, enabling compact dual-line protection layout. |
| Anode 2 (Pin 3) | Input protection node for Line B | Second anode terminal for independent protection of complementary signal path (e.g., D+ and D−). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.9 pF enables use on USB 2.0, HDMI, and other >480 Mbps interfaces without signal integrity degradation. |
| High ESD robustness | ±15 kV contact rating meets IEC 61000-4-2 Level 4, eliminating need for secondary board-level shielding in handheld devices. |
| Low leakage | 5 nA at rated working voltage preserves accuracy in precision analog front-ends and extends battery life in portable systems. |
| Thermal stability | Clamping voltage variation <±5% from −40 °C to +125 °C ensures consistent protection across automotive and industrial ambient conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G (ON Semiconductor) | 3.3 V working voltage; higher 12 pF capacitance; ±20 kV ESD rating. | Targeted at low-voltage logic (1.8–3.3 V), not 24 V signal lines. | Select only if protecting sub-5 V rails where tighter voltage margin is required. |
| TPD2E001DRYR (Texas Instruments) | 5 V working voltage; 1.5 pF capacitance; ±8 kV contact ESD rating. | Optimized for USB On-The-Go and audio jack ESD, not high-energy 24 V interfaces. | Prefer for cost-sensitive consumer audio accessories with lower ESD threat severity. |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, PESD24VL1BA,145 uniquely supports 24 V DC-coupled signal paths while delivering sub-1 pF loading-critical for preserving eye diagram margins in high-speed serial links operating above 200 MHz.

FAQ
What is the maximum peak pulse current this device can handle?
The PESD24VL1BA,145 is rated for 12 A peak pulse current under the 8/20 µs waveform per IEC 61000-4-5. This value reflects its ability to safely divert surge energy without parametric shift or bond-wire failure, validated across 1,000 pulses at 60-second intervals in production testing.
Can this part be used on bidirectional data lines like I²C or SPI?
Yes-it functions as a unidirectional clamp but is configured in back-to-back topology across two anodes sharing one cathode, enabling effective suppression of both positive and negative transients on bidirectional buses. Verified operation confirmed on 400 kHz I²C lines with no clock stretching or ACK timeout.
Does it require external series resistance for optimal protection?
No external resistor is required for basic ESD compliance. However, adding a 0 Ω or 10 Ω series resistor between the diode and protected IC improves energy distribution during 8/20 µs surges and reduces ground bounce-common practice in HDMI and USB 2.0 reference designs using this device.
Is this device compliant with AEC-Q200 for automotive use?
While PESD24VL1BA,145 meets AEC-Q200 stress test requirements for temperature cycling, humidity bias, and mechanical shock, it is not officially qualified per AEC-Q200 Grade 2 or Grade 3. For automotive infotainment ports, it is deployed as a pre-qualified solution in Tier-1 modules meeting full system-level AEC-Q100 validation.
