Product details
Overview
PESD5V0L1BA-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 (±30 kV contact), IEC 61000-4-5 surge (15 A, 8/20 µs), with 5 V reverse standoff voltage, 75 pF capacitance, and 33 V clamping voltage at 15 A. It is qualified to AEC-Q101 for automotive CAN bus and data line 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 interfaces where leakage (<0.01 µA), clamping performance, and automotive qualification are critical design constraints.
Technical Context
This dual-cathode, bidirectional TVS diode implements a symmetrical clamp structure across two anti-parallel diodes sharing a common cathode configuration (K1/K2), enabling protection of AC-coupled or bipolar signal lines without polarity sensitivity. Its layout supports direct placement at I/O connectors with minimal trace inductance.
The device operates within a junction temperature range of –65 °C to 150 °C and maintains stable clamping (VCL ≤ 33 V at IPPM = 15 A) and ultra-low leakage (IRM = 0.01 µA at VRWM = 5 V), meeting stringent requirements for high-speed data lines including CAN FD and USB 2.0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction; defines safe signal swing margin for 3.3 V/5 V buses. |
| Clamping Voltage | 33 V at 15 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge; ensures downstream ICs remain below absolute max ratings. |
| Diode Capacitance | 75 pF at 1 MHz, 0 V - Low enough to avoid signal integrity degradation on CAN, I²C, and UART lines up to 1 Mbps. |
| ESD Withstand | ±30 kV contact (IEC 61000-4-2 Level 4) - Full immunity to human-body ESD events at connector-level exposure points. |
| Peak Pulse Power | 500 W (8/20 µs) - Sustains high-energy transients without thermal runaway, validated per IEC 61000-4-5. |
| Leakage Current | 0.01 µA at 5 V - Negligible DC loading on high-impedance sensor or reference lines; avoids measurement drift. |
| Breakdown Voltage | 7.6 V typical (5 mA) - Ensures clean turn-on above normal signal excursions while avoiding false triggering. |
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 end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Forms one half of symmetrical bidirectional clamp; connects to protected line when used in standard dual-cathode configuration. |
| 2 (K2) | Cathode of Diode 2 | Completes anti-parallel pair; both cathodes tied to ground in standard layout, enabling clamping for ± transients on a single line. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Single-device solution for AC-coupled or reversible signal paths (e.g., CAN H/L, RS-485, audio differential pairs). |
| AEC-Q101 Qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress-enables use in infotainment, ADAS sensor interfaces. |
| Ultra-Low Capacitance | 75 pF enables <1% signal distortion on 10 MHz digital signals; suitable for USB 2.0 D+/D– and MIPI D-PHY lanes. |
| Low Clamping Ratio | VCL/VBR ≈ 4.3 - Efficient energy diversion with minimal overvoltage overshoot during fast transients. |
| Sub-µA Leakage | 0.01 µA at rated VRWM - Preserves battery life in always-on automotive modules and avoids bias shift in precision analog front-ends. |
Applications
| CAN Bus Protection | Automotive Sensor Interface |
|---|---|
|
Use Scenario: Protecting CAN H and CAN L lines in vehicle ECUs against ESD from cable harness handling and load dump coupling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at OBD-II connector or module header, clamping ±30 kV ESD pulses to <33 V. Use Value: Prevents CAN controller latch-up or PHY damage while maintaining <75 pF loading to preserve bit timing integrity at 500 kbps–1 Mbps. |
Use Scenario: Shielding LIN or SENT sensor outputs (e.g., pressure, temperature) from board-level ESD during assembly and field service. IC Role / Device Role / Timing Role: Low-leakage (0.01 µA) standoff protector on unidirectional analog/digital sensor lines, grounded via K1/K2 tie point. Use Value: Eliminates false triggers and offset errors caused by leakage-induced voltage drop across high-impedance sensor pull-ups. |
| USB 2.0 Data Line Protection | Industrial HMI Touch Interface |
|
Use Scenario: Safeguarding D+ and D– lines in automotive infotainment USB ports against hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Dual-cathode ESD array (one device per line) with 75 pF capacitance, placed within 3 mm of USB connector pins. Use Value: Maintains eye diagram compliance at 480 Mbps by limiting capacitive loading and ensuring sub-35 V clamping during ±15 kV air discharge. |
Use Scenario: Protecting projected capacitive (PCAP) touch controller I²C lines and reset inputs in factory HMIs exposed to operator ESD. IC Role / Device Role / Timing Role: Standoff-rated (5 V) clamp on 3.3 V I²C SDA/SCL, leveraging bidirectional symmetry to handle both logic-high and logic-low transients. Use Value: Avoids I²C bus lockup during ESD events while adding <1 ns propagation delay-no firmware intervention required. |
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 SZ1.5SMC5.0AT3G | Unidirectional, higher VRWM (5.0 V), higher VCL (11.2 V @ 100 A), larger SMC package (7.1 mm × 6.2 mm) | Requires external series resistor for bidirectional use; unsuitable for space-constrained PCBs or high-speed lines due to >100 pF capacitance | Select only if peak surge current >15 A is required and board area permits SMC footprint. |
| Vishay ESDBLE5.0D1W | Bidirectional, same SOD323 package, lower VCL (14.5 V @ 12 A), but higher Cd (110 pF) and no AEC-Q101 qualification | Acceptable for consumer USB/I²C, but not certified for automotive environments requiring AEC-Q101 traceability | Prefer for cost-sensitive non-automotive designs where clamping voltage priority outweighs leakage and qualification needs. |
Compared with SZ1.5SMC5.0AT3G and ESDBLE5.0D1W, PESD5V0L1BA-Q uniquely balances AEC-Q101 compliance, 75 pF capacitance, and 33 V clamping in SOD323-making it optimal for automotive CAN, LIN, and USB 2.0 where size, speed, and qualification are jointly constrained.

FAQ
What is the maximum operating temperature for PESD5V0L1BA-Q?
The PESD5V0L1BA-Q has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of –65 °C to 150 °C. Its thermal resistance (Rthj-a) is optimized for SOD323 mounting on standard FR-4 PCBs with recommended solder land patterns per Figure 10 of the datasheet.
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 for CAN H and one for CAN L, each installed with K1/K2 tied to ground and the anode side connected to the respective line.
Does this device require a series impedance for optimal ESD performance?
No external series resistor is required. The device's differential resistance (Rdiff = 80 Ω typical) and low clamping voltage enable direct connection between protected line and ground. Layout best practice mandates placement within 3 mm of the connector with minimized ground path inductance.
How does the 75 pF capacitance impact 100 Mbps Ethernet PHY lines?
75 pF exceeds typical Ethernet PHY tolerance (≤5 pF for 100BASE-TX), making PESD5V0L1BA-Q unsuitable for Ethernet physical layer protection. It is validated for CAN, LIN, USB 2.0, I²C, and audio lines where bandwidth ≤10 MHz and capacitance ≤100 pF are acceptable.
