Product details
Overview
PESD24VL1BA-Q from Nexperia is a bidirectional ESD protection diode in SOD323 package, designed to protect single signal lines against IEC 61000-4-2 level 4 (±23 kV contact) and IEC 61000-4-5 surge transients (3 A, 8/20 µs). It features 24 V reverse standoff voltage, 11 pF capacitance at 1 MHz, and 70 V clamping voltage at 3 A, making it suitable for high-speed CAN bus and data line protection in automotive electronics.
For engineers reviewing the PESD24VL1BA-Q datasheet, PESD24VL1BA-Q pinout, PESD24VL1BA-Q application, or PESD24VL1BA-Q equivalent, key selection criteria include low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, bidirectional clamping capability, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a transient voltage suppression (TVS) diode with symmetrical bidirectional clamping behavior, enabling protection of AC-coupled or dual-polarity signal lines without polarity constraints. Its silicon avalanche structure delivers fast response (<1 ns) to ESD events and maintains stable clamping performance across junction temperatures up to 150 °C.
The diode is optimized for low-capacitance interfaces: its 11 pF typical capacitance minimizes signal distortion on high-frequency lines such as CAN FD, USB 2.0, or audio differential pairs, while its 300 Ω differential resistance ensures minimal insertion loss under normal operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse voltage before leakage exceeds 1 nA; defines safe operating range for protected line. |
| Cd | 11 pF - Capacitance at 1 MHz and 0 V bias; enables use on data lines up to ~300 Mbps without significant rise-time degradation. |
| VCL @ 3 A | 70 V - Clamping voltage during 8/20 µs surge; limits transient energy delivered to downstream ICs. |
| PPPM | 200 W - Peak pulse power handling per IEC 61000-4-5; supports robust surge immunity in harsh environments. |
| ESD Rating | ±23 kV - Contact discharge per IEC 61000-4-2 level 4; exceeds automotive ESD immunity requirements. |
| IRM | <1 nA - Reverse leakage at VRWM; prevents DC loading or battery drain in always-on systems. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked with bar on end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | One terminal of symmetrical bidirectional avalanche junction; connects to protected line. |
| 2 (K2) | Cathode 2 | Second terminal of same junction; connects to system ground or reference plane. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or polarity-agnostic lines (e.g., CAN H/L, RS-485) without external biasing. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, infotainment, and ADAS sensor interfaces. |
| Ultra-low leakage | <1 nA at 24 V ensures negligible current draw in battery-powered or low-power wake-up circuits. |
| Small SOD323 footprint | Minimizes PCB area and parasitic inductance-critical for effective ESD suppression near connectors. |
Applications
| CAN Bus Protection | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protecting CAN H and CAN L differential pair in automotive ECUs against ESD events during connector mating or cable handling. IC Role / Device Role / Timing Role: Bidirectional TVS diode placed directly at connector entry point to clamp transients before reaching CAN transceiver. Use Value: Maintains signal integrity with 11 pF capacitance while meeting ISO 10605 and AEC-Q101 requirements for automotive durability. | Use Scenario: Shielding D+ and D− lines of USB 2.0 ports in industrial HMIs or medical devices from user-induced ESD.

| Audio Line Inputs | Industrial Sensor Interfaces |
Use Scenario: Safeguarding balanced analog audio inputs (e.g., XLR or TRS) in professional audio equipment exposed to handling ESD. IC Role / Device Role / Timing Role: Symmetrical clamping device protecting both hot and cold signal paths relative to chassis ground. Use Value: Eliminates audible pop/click artifacts caused by transient coupling while preserving wideband frequency response. | Use Scenario: Protecting 4–20 mA or 0–10 V analog sensor outputs in factory automation systems subject to field wiring surges. IC Role / Device Role / Timing Role: Standoff-rated TVS element placed between sensor output and PLC input to absorb induced transients.

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 | Lower VRWM (3.3 V), higher Cd (100 pF), unidirectional configuration | Requires series resistor for bidirectional line protection; unsuitable for 24 V systems | Select only for low-voltage logic lines where clamping voltage must be <5 V. |
| TPD2E001DRYR | 2-channel array, 10 pF per line, ±8 kV ESD rating, no AEC-Q101 qualification | Lacks automotive qualification and 23 kV ESD margin; intended for consumer-grade USB/HDMI | Prefer for cost-sensitive non-automotive designs needing multi-line integration. |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, PESD24VL1BA-Q uniquely combines 24 V standoff, 23 kV ESD immunity, AEC-Q101 qualification, and 11 pF capacitance-making it the only option validated for robust CAN bus protection in automotive Grade 2 environments.

FAQ
What is the maximum operating temperature for PESD24VL1BA-Q?
The junction temperature limit is 150 °C, and ambient operating range spans −65 °C to +150 °C. Thermal derating applies above 25 °C ambient: peak pulse power drops to ~70% at 125 °C junction per Figure 4 in the datasheet. PCB layout must ensure adequate thermal relief via copper pour or vias to maintain reliability under repeated surge stress.
Can PESD24VL1BA-Q protect DC power rails?
No-it is explicitly not designed for DC supply line protection. The device lacks sufficient power dissipation capability and clamping characteristics for sustained overvoltage events. Its 24 V VRWM and 70 V VCL are optimized for signal-level transients, not continuous overvoltage. Use dedicated TVS arrays or polymeric PPTCs for power rail protection.
How does the SOD323 package affect PCB layout for optimal ESD performance?
Placement within 3 mm of the protected connector and direct routing to ground via short, wide traces (≥0.5 mm) is essential. Avoid vias in the protection path; use solid ground plane beneath the device. Footprint dimensions (1.7 × 1.25 mm) require precise stencil aperture (0.5 mm × 0.6 mm) for reflow to prevent tombstoning and ensure mechanical stability under thermal cycling.
Is PESD24VL1BA-Q compatible with lead-free reflow processes?
Yes-it is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. Recommended profile uses ramp rate ≤3 °C/s, preheat 150–200 °C for 60–120 s, soak 200–220 °C for 60–120 s, and peak at 245–260 °C for ≤10 s. Solder paste volume must match SOD323 footprint in Figure 9 of the datasheet.
