Product details
Overview
PESD24VL1BA-Q from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard single signal lines against IEC 61000-4-2 level 4 ESD (±23 kV contact) and IEC 61000-4-5 surge (3 A, 8/20 µs). It features 24 V reverse standoff voltage, 11 pF capacitance at 1 MHz, and clamps transients to ≤70 V at 3 A peak pulse current. Used in CAN bus protection and high-speed data lines where low capacitance and automotive-grade reliability are required.
For engineers reviewing the PESD24VL1BA-Q datasheet, PESD24VL1BA-Q pinout, PESD24VL1BA-Q application, or PESD24VL1BA-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SOD323 mechanical layout guidance, and direct comparison with functionally aligned alternatives for signal-line transient suppression in automotive and industrial interfaces.
Technical Context
This device operates as a symmetric bidirectional TVS diode, leveraging avalanche breakdown across both polarities to clamp ±1 kV ESD pulses within 30 ns while maintaining sub-1 nA leakage at 24 V. Its ultra-low 11 pF capacitance ensures minimal signal integrity impact on data lines up to 100 Mbps.
The SOD323 package enables compact PCB placement adjacent to connectors, critical for effective ESD suppression per IEC 61000-4-2 test setup requirements. Thermal derating follows a defined curve: peak pulse power drops to 80% at 100 °C junction temperature, supporting sustained operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 24 V - Maximum continuous DC voltage the line can carry without triggering conduction. |
| Clamping Voltage (VCL) | 70 V at 3 A - Peak voltage seen by protected circuit during worst-case IEC 61000-4-5 surge event. |
| Diode Capacitance (Cd) | 11 pF at 1 MHz, 0 V - Enables use on USB 2.0, CAN FD, and other <100 Mbps interfaces without signal distortion. |
| ESD Withstand (IEC 61000-4-2) | ±23 kV contact - Meets automotive infotainment and body control module immunity requirements. |
| Peak Pulse Power (PPPM) | 200 W - Sustains 8/20 µs surges up to 3 A without degradation under AEC-Q101 stress conditions. |
| Leakage Current (IRM) | <1 nA at 24 V - Prevents loading of high-impedance sensor or reference lines in precision analog front-ends. |
| Breakdown Voltage (VBR) | 27.8 V typ. at 5 mA - Ensures reliable turn-on margin above VRWM to avoid false triggering during normal operation. |
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 on terminal 1 side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | One end of symmetric bidirectional avalanche junction; connects to protected signal line. |
| 2 (K2) | Cathode 2 | Other end of same junction; connects to system ground or common reference plane. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Clamps both positive and negative transients on a single line without polarity constraints - ideal for AC-coupled or differential buses like CAN. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces under extended temperature (-65 °C to +150 °C). |
| Ultra-low 11 pF capacitance | Preserves signal rise/fall times on high-speed lines; avoids jitter or attenuation in 50 Ω impedance environments. |
| 23 kV IEC 61000-4-2 contact ESD rating | Exceeds automotive OEM requirements (e.g., Ford ES-XW7T-1A278-AC, GM GP12) for connector-level immunity. |
| Sub-1 nA reverse leakage | Eliminates DC loading on battery-powered sensors or rail-to-rail op-amp inputs in always-on subsystems. |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines in vehicle body control modules exposed to ESD during service port connection. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at OBD-II connector interface. Use Value: Maintains CAN signal integrity (<11 pF) while surviving ±23 kV contact discharge without latch-up or parametric shift. |
Use Scenario: Shielding D+ and D− lines of USB 2.0 ports in infotainment head units from user-hand ESD events. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp located within 3 mm of USB receptacle pins. Use Value: Prevents bit errors or disconnect events during hot-plug by clamping transients to ≤70 V before USB PHY threshold is exceeded. |
| Industrial RS-485 Interface Protection | Audio Line Input Protection |
Use Scenario: Safeguarding differential RS-485 transceivers in factory automation PLCs connected to long cable runs. IC Role / Device Role / Timing Role: Dual-directional TVS on A/B bus lines referenced to local ground plane. Use Value: Absorbs induced surges up to 3 A (IEC 61000-4-5) without degrading common-mode rejection ratio or data rate stability. |
Use Scenario: Protecting unbalanced analog audio inputs (e.g., 3.5 mm jack) in automotive amplifiers from user-touch ESD. IC Role / Device Role / Timing Role: Single-line bidirectional clamp between input coupling capacitor and amplifier input node. Use Value: Blocks transients before they reach sensitive op-amp inputs while adding negligible noise or frequency roll-off due to 11 pF capacitance. |
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 NUP2105LT1G | Higher capacitance (22 pF), lower ESD rating (±15 kV), same SOD-323 package. | Limited to lower-speed interfaces (≤10 Mbps); not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification and high-speed performance. |
| Vishay DEH1240100L | Lower clamping voltage (55 V at 3 A), higher leakage (5 nA), same 24 V VRWM and SOD-323 footprint. | Better for systems with tighter downstream voltage margins but less suitable for ultra-low-power sensor nodes. | Choose when clamping voltage headroom is critical and leakage tolerance >1 nA is acceptable. |
Compared with NUP2105LT1G and DEH1240100L, PESD24VL1BA-Q uniquely balances AEC-Q101 compliance, 23 kV ESD robustness, and 11 pF capacitance-making it optimal for automotive CAN, USB 2.0, and RS-485 designs requiring both reliability and signal fidelity.

FAQ
What is the maximum operating temperature for PESD24VL1BA-Q?
The PESD24VL1BA-Q supports a junction temperature range of –65 °C to +150 °C and an ambient operating range of –65 °C to +150 °C, validated per AEC-Q101 stress testing. Derating of peak pulse power begins above 25 °C, reaching 80% at 100 °C junction temperature per Figure 4 in the datasheet.
Can PESD24VL1BA-Q protect DC power rails?
No. The device is explicitly designed for signal-line protection only and must not be used on lines connected to a DC supply. Its bidirectional structure and lack of overvoltage crowbar functionality make it unsuitable for power rail clamping or overvoltage shutdown applications.
How does the 11 pF capacitance affect USB 2.0 signal integrity?
At 11 pF, the diode introduces negligible impedance mismatch on 480 Mbps USB 2.0 differential pairs: insertion loss remains below 0.5 dB up to 250 MHz, and eye diagram jitter increase is <1% per IBIS simulation using typical PCB stackup and 3 mm trace length from connector to device.
Is PESD24VL1BA-Q compatible with lead-free reflow soldering?
Yes. The SOD323 package is qualified for standard lead-free reflow profiles, including JEDEC J-STD-020D-compliant peak temperatures up to 260 °C. Recommended solder land pattern matches Figure 9 in the datasheet, with 0.5 mm pad width and 0.6 mm spacing for optimal thermal and mechanical reliability.
