Product details
Overview
PESD24VV1BA-QX from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one low-speed signal line against IEC 61000-4-2 ESD events up to ±30 kV, with 24 V reverse stand-off voltage, 33 V clamping at 3.5 A peak pulse, and 14–17 pF capacitance - used in automotive infotainment data lines.
For engineers reviewing the PESD24VV1BA-QX datasheet, PESD24VV1BA-QX pinout, PESD24VV1BA-QX application, or PESD24VV1BA-QX equivalent, key selection criteria include bidirectional clamping performance, ultra-low leakage (<1 nA), AEC-Q101 qualification, and minimal capacitive loading for signal integrity on CAN, LIN, or sensor interfaces.
Technical Context
This device implements a symmetric dual-cathode TVS structure enabling bidirectional transient suppression without polarity constraints. It operates across –24 V to +24 V reverse stand-off range and delivers sub-33 V clamping under 3.5 A 8/20 µs surges per IEC 61000-4-5.
Its 14–17 pF capacitance at 0 V bias and <1 nA leakage at 24 V support high-fidelity analog and low-speed digital signals. The AEC-Q101 qualification confirms robustness for automotive ambient temperatures (–55 °C to +150 °C) and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 24 V - maximum continuous working voltage before conduction begins; ensures no interference during normal signal operation. |
| Clamping Voltage (VCL) | 33 V at IPP = 3.5 A - peak voltage seen by protected circuit during worst-case surge; limits downstream IC stress. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - withstands human-body-model-level ESD events without degradation. |
| Diode Capacitance (Cd) | 14–17 pF at 1 MHz, 0 V - low enough to avoid signal distortion on ≤10 Mbps interfaces like LIN or analog sensors. |
| Leakage Current (IRM) | <1 nA at VR = 24 V - negligible DC loading on high-impedance sensor or reference lines. |
| Dynamic Resistance (Rdyn) | 0.16 Ω - enables fast response and low-voltage overshoot during nanosecond-scale ESD transients. |
| Peak Pulse Current (IPPM) | 3.5 A (8/20 µs waveform) - supports industrial and automotive surge immunity requirements per IEC 61000-4-5. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to protected line; forms one half of symmetrical clamping path to ground. |
| 2 | K2 (cathode of diode 2) | Connects to ground; completes bidirectional clamp path for both positive and negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables single-device protection of AC-coupled or bipolar signal lines (e.g., LIN bus, analog sensor outputs) without external polarity biasing. |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin environments including thermal cycling, humidity, and mechanical shock per discrete semiconductor stress test standard. |
| Ultra-low leakage current | <1 nA at 24 V ensures minimal power loss and offset error in precision analog front-ends and battery-powered modules. |
| Low dynamic resistance | 0.16 Ω minimizes voltage overshoot during fast-rising ESD pulses (e.g., 0.6–1 ns rise time), improving protection margin. |
| Small-footprint SOD323 package | 1.7 mm × 1.25 mm footprint allows placement directly at board edge connectors with minimal PCB trace inductance. |
Applications
| Automotive LIN Bus Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN transceiver pins in body control modules exposed to ESD during service or assembly. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed between LIN PHY and connector, clamping ±30 kV ESD pulses within 1 ns.

| Consumer USB 2.0 ID Line Protection | Medical Patient Monitor Analog Inputs |
Use Scenario: ESD hardening of USB ID pin in OTG-capable portable devices where polarity switching occurs. IC Role / Device Role / Timing Role: Symmetric clamp on bidirectional ID line, operating across –24 V to +24 V without bias network. Use Value: Eliminates need for dual-diode array or resistor-divider biasing, reducing BOM count and layout area by 40%. |
Use Scenario: Safeguarding isolated analog front-end inputs in Class II medical monitors handling biopotential signals. IC Role / Device Role / Timing Role: First-stage ESD filter on differential electrode inputs, placed before instrumentation amplifier with <1 nA leakage. Use Value: Preserves common-mode rejection ratio (CMRR) and input impedance >10 GΩ while meeting IEC 61000-4-2 Level 4 immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC27AT3G | Unidirectional, higher VRWM (27 V), larger SMC package (7.1 mm × 6.2 mm), 100 pF capacitance. | Requires external series resistor for bidirectional use; unsuitable for high-speed or space-constrained layouts. | Select only if higher surge rating (1500 W) outweighs size and capacitance penalties in non-automotive industrial designs. |
| Vishay ESDBLE5.0D1W | Bidirectional, lower VRWM (5 V), 0.65 pF capacitance, same SOD323 footprint, but rated only to ±15 kV ESD. | Optimized for USB 2.0/3.0 data lines; insufficient for 24 V automotive supply-rail proximity. | Prefer for low-voltage, high-speed interfaces; avoid where 24 V system coupling or AEC-Q101 compliance is required. |
Compared with SZ1.5SMC27AT3G and ESDBLE5.0D1W, PESD24VV1BA-QX uniquely balances 24 V system compatibility, ±30 kV ESD robustness, AEC-Q101 qualification, and 15 pF loading - making it optimal for automotive LIN, sensor, and medium-voltage industrial I/O protection.

FAQ
Is PESD24VV1BA-QX unidirectional or bidirectional?
PESD24VV1BA-QX is a bidirectional ESD protection diode, confirmed by its symmetric V-I characteristics (Fig. 3), dual-cathode pinning (K1/K2), and explicit designation as "bidirectional" in the general description and application information sections of the datasheet.
What is the maximum junction temperature and storage temperature range?
The absolute maximum junction temperature (Tj) is 150 °C, and the storage temperature (Tstg) range is –65 °C to +150 °C, both specified in Table 5 (Limiting values) and validated under AEC-Q101 thermal cycling and high-temperature operating life tests.
Does PESD24VV1BA-QX require an external bias or series resistor?
No external bias or series resistor is required. Its bidirectional architecture allows direct placement between signal line and ground, as shown in Figure 12 (application diagram); the device conducts symmetrically for both polarities without auxiliary components.
How does its 14–17 pF capacitance affect signal integrity on a 100 kHz analog sensor line?
At 100 kHz, the capacitive reactance (Xc ≈ 100 kΩ for 15 pF) introduces negligible loading on typical sensor output impedances (<10 kΩ), resulting in <0.01 dB gain error and no measurable phase shift - verified by low-frequency impedance modeling in Nexperia's application notes.
