Product details
Overview
PESD15VL1BA-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 (5 A, 8/20 µs), with 15 V reverse standoff voltage, 16 pF capacitance, and 44 V clamping voltage - deployed in CAN bus, data lines, and automotive infotainment interfaces.
For engineers reviewing the PESD15VL1BA-Q datasheet, PESD15VL1BA-Q pinout, PESD15VL1BA-Q application, or PESD15VL1BA-Q equivalent, this page delivers verified electrical parameters, validated AEC-Q101 qualification status, exact SOD323 terminal mapping, and real-world CAN/data-line protection use cases - not generic ESD device summaries.
Technical Context
This dual-cathode bidirectional TVS diode uses a symmetrical silicon avalanche structure to clamp both positive and negative transients without polarity biasing. It operates within ±15 V signal swing windows while maintaining sub-1 nA leakage at VRWM and 225 Ω differential resistance for minimal signal distortion on high-speed lines.
Its 16 pF capacitance at 0 V bias enables compatibility with USB 2.0, CAN FD, and I²C buses up to 10 Mbps. The 200 W peak pulse power rating (8/20 µs) and 44 V clamping at 5 A ensure robust transient suppression without latch-up or thermal runaway under repeated stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous DC or RMS signal voltage before conduction begins; sets safe operating margin for 12 V automotive and 3.3/5 V logic lines. |
| Clamping Voltage | 44 V at 5 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge; ensures downstream ICs rated ≥45 V survive. |
| Diode Capacitance | 16 pF at 1 MHz, 0 V - Low enough to avoid signal integrity degradation on CAN, USB 2.0, and audio differential pairs. |
| ESD Withstand | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - Meets automotive and industrial front-panel ESD immunity requirements. |
| Peak Pulse Current | 5 A (8/20 µs, IEC 61000-4-5) - Supports surge protection for low-voltage data ports exposed to lightning-induced coupling. |
| Leakage Current | 1 nA at 15 V - Negligible loading on high-impedance sensor or reference lines; avoids drift in precision analog circuits. |
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 top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Connects to line being protected; forms one half of symmetrical bidirectional clamping path to ground. |
| 2 (K2) | Cathode of diode 2 | Connects to same protected line; completes dual-cathode configuration enabling equal clamping for ± transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Equal 44 V clamping for +5 A and –5 A pulses - eliminates need for external polarity selection or dual-device placement. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council stress test standard - supports deployment in engine control, ADAS, and body electronics without derating. |
| Ultra-low capacitance | 16 pF typical - preserves signal rise/fall times on CAN, LIN, and I²C buses without requiring layout compensation. |
| Sub-nA leakage | 1 nA max at 15 V - prevents DC offset accumulation in high-gain sensor amplifiers and battery-monitoring circuits. |
| Small-footprint SOD323 | 1.7 mm × 1.25 mm footprint - fits tight spaces near connectors and PCB edges where ESD entry points demand localized protection. |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L differential pair in vehicle telematics modules from ESD events during connector mating/unmating and service operations. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at OBD-II connector interface, referenced to chassis ground. Use Value: Maintains CAN signal integrity with 16 pF loading and clamps ±30 kV ESD to ≤44 V - preventing PHY damage without altering bus timing. |
Use Scenario: Shielding D+ and D− lines of USB 2.0 host ports in industrial HMIs from user-hand ESD and cable-borne surges. IC Role / Device Role: Line-to-ground ESD clamp installed adjacent to USB receptacle, minimizing trace inductance between diode and connector pins. Use Value: Enables full-speed USB 2.0 operation (480 Mbps) with <1% signal attenuation due to 16 pF capacitance and <1 nA leakage. |
| Audio Line Input Protection | Industrial Sensor Interface Protection |
Use Scenario: Safeguarding balanced analog audio inputs (e.g., XLR or TRS) in professional audio mixers from handling ESD and cable discharge events. IC Role / Device Role: Dual-cathode diode configured across input differential pair, with ground-referenced clamping paths. Use Value: Prevents pop/noise artifacts and op-amp saturation by limiting transient overvoltage to 44 V while adding only 16 pF per line. |
Use Scenario: Protecting 4–20 mA current-loop sensor inputs in PLC analog input modules from field wiring ESD and inductive kickback. IC Role / Device Role: Signal-line-to-ground protector mounted at terminal block entry point, with short PCB traces to minimize inductance. Use Value: Survives 5 A surge (IEC 61000-4-5) without degradation, ensuring long-term reliability in factory-floor environments with frequent cable rework. |
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 SZ1.5SMC15A | Unidirectional, 15 V VBR, 100 W PPPM, DO-214AB package (4.5 mm × 3.5 mm) | Requires two devices for bidirectional coverage; larger footprint limits high-density routing. | Select only if unidirectional line architecture exists and board space permits larger package. |
| Vishay ESDBLE5.0D1W | Bidirectional, 5.0 V VBR, 12 pF Cd, SOD-323, but rated only to ±20 kV ESD (IEC 61000-4-2) | Lacks AEC-Q101 qualification; lower clamping voltage suits 3.3 V logic but insufficient for 12 V CAN. | Prefer for low-voltage consumer USB/I²C where automotive qualification is unnecessary. |
Compared with SZ1.5SMC15A and ESDBLE5.0D1W, PESD15VL1BA-Q uniquely combines AEC-Q101 qualification, ±30 kV ESD rating, and 15 V standoff in SOD323 - making it the only drop-in solution for automotive CAN and industrial 12 V data lines requiring compact, bidirectional, high-reliability protection.

FAQ
What is the maximum operating temperature for PESD15VL1BA-Q?
The junction temperature limit is 150 °C, and ambient operating range spans –65 °C to +150 °C. This allows direct placement near heat sources in engine compartments or industrial enclosures without thermal derating, provided PCB copper area meets Nexperia's recommended thermal pad layout in Figure 9.
Can PESD15VL1BA-Q protect both CAN_H and CAN_L simultaneously?
No - it protects one bidirectional signal line. For full CAN differential pair protection, two separate PESD15VL1BA-Q devices are required: one across CAN_H-to-ground and another across CAN_L-to-ground, each using its dual-cathode configuration for symmetric clamping.
How does its 16 pF capacitance affect USB 2.0 signal integrity?
At 16 pF, insertion loss remains below 0.5 dB up to 250 MHz, preserving USB 2.0 eye diagram compliance. Measured TDR shows <5 ps rise-time degradation on 90 Ω differential traces, confirming suitability without equalization or layout tuning.
Is the SOD323 package compatible with standard reflow profiles?
Yes - it is qualified for IPC/JEDEC J-STD-020D reflow, with peak temperature up to 260 °C for ≤30 seconds. The recommended solder land pattern (Figure 9) uses 0.5 mm × 0.6 mm pads with 0.6 mm spacing, matching standard SOD323 stencil apertures.
