Product details
Overview
PESD5V0L1BA-Q from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 5 V reverse standoff voltage, 75 pF capacitance at 1 MHz, 33 V clamping voltage at 15 A surge, and AEC-Q101 qualification for automotive CAN bus protection.
For engineers reviewing the PESD5V0L1BA-Q datasheet, PESD5V0L1BA-Q pinout, PESD5V0L1BA-Q application, or PESD5V0L1BA-Q equivalent, this device is selected for low-capacitance, high-reliability transient suppression on bidirectional data lines where leakage (<0.01 µA), compact footprint, and automotive-grade robustness are critical.
Technical Context
This dual-cathode ESD diode implements a symmetrical back-to-back PN junction configuration enabling bidirectional clamping without polarity constraints. It operates within ±5 V signal swing envelopes while maintaining sub-80 Ω differential resistance and stable 75 pF capacitance across 0–5 V reverse bias.
Its 8/20 µs surge rating of 15 A and 500 W peak pulse power align with IEC 61000-4-5 requirements, and its 150 °C max junction temperature supports under-hood automotive deployment when mounted per recommended PCB layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before leakage rises significantly; defines safe signal swing range. |
| Clamping Voltage | 33 V at 15 A - Peak voltage seen by protected circuit during worst-case 8/20 µs surge; limits stress on downstream ICs. |
| Diode Capacitance | 75 pF at 1 MHz, 0 V - Low enough for USB 2.0, CAN FD, and audio line protection without signal integrity degradation. |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 level 4 - Withstands repeated human-body ESD events without parametric shift or failure. |
| Peak Pulse Current | 15 A (8/20 µs) - Supports industrial surge immunity per IEC 61000-4-5 up to 1 kV line-to-ground. |
| Leakage Current | 0.01 µA at 5 V - Ensures minimal DC loading on high-impedance sensor or communication lines. |
| Package | SOD323 (SC-76) - 1.7 × 1.25 × 0.95 mm surface-mount outline compatible with standard reflow profiles. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to protected line; forms one half of symmetrical clamping path to ground. |

| AEC-Q101 qualified | Validated for automotive use including engine control units, body electronics, and infotainment interfaces. |
| Ultra-low leakage | 0.01 µA ensures no measurable DC offset or battery drain in always-on sensor or LIN bus applications. |
| Low 75 pF capacitance | Maintains signal rise/fall times <1 ns on 50 Ω lines-critical for high-speed data integrity in USB and audio paths. |
| 500 W peak pulse power | Handles multiple surge events without thermal runaway, supporting long-term reliability in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (120 pF), lower clamping (27 V at 12 A), same SOD-323 package. | Better for low-voltage logic protection but unsuitable for USB 2.0 due to excessive capacitance. | Select when clamping voltage priority outweighs speed; verify signal bandwidth impact. |
| Vishay VEML5010-001 | Single-diode unidirectional configuration; 5.5 V VRWM; 100 pF; not AEC-Q101 qualified. | Limited to DC-biased lines; lacks automotive qualification and bidirectional capability. | Only for cost-sensitive non-automotive consumer designs with fixed-polarity signals. |
Compared with NUP4105MR6T1G and VEML5010-001, PESD5V0L1BA-Q uniquely balances ultra-low capacitance, automotive qualification, and true bidirectional operation-making it the only choice for CAN FD, USB 2.0, and AEC-compliant sensor interfaces requiring zero polarity assumptions.

FAQ
What is the maximum operating temperature for PESD5V0L1BA-Q?
The PESD5V0L1BA-Q has a maximum junction temperature of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal performance is validated per AEC-Q101, making it suitable for under-hood automotive locations where PCB temperatures may exceed 125 °C during extended operation.
Can PESD5V0L1BA-Q protect both CAN_H and CAN_L simultaneously?
No-PESD5V0L1BA-Q protects a single bidirectional line. For full CAN bus protection, two devices are required: one placed between CAN_H and ground, and another between CAN_L and ground. Each device uses its dual-cathode structure to clamp both polarities of that individual line.
Is the 75 pF capacitance measured at zero bias or operating voltage?
The 75 pF typical capacitance is measured at 1 MHz with 0 V reverse bias and 25 °C ambient temperature. Capacitance decreases slightly with increasing reverse voltage (e.g., ~50 pF at 5 V), as confirmed in Figure 5 of the datasheet, ensuring optimal high-frequency performance across its operating range.
Does PESD5V0L1BA-Q require external series impedance for optimal ESD performance?
No external series resistor is required for basic ESD clamping. However, placing a small ferrite bead or 0 Ω resistor between the diode and protected IC improves high-frequency filtering and reduces ringing. Layout best practices-especially minimizing trace length to ground-matter more than added components for effective IEC 61000-4-2 compliance.
