Product details
Overview
PESD3V3T1BL-Q from Nexperia is a bidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to protect one signal line against IEC 61000-4-2 contact discharge up to ±30 kV and IEC 61000-4-5 surges up to 10 A (8/20 µs), with clamping voltage ≤11 V at 10 A and reverse standoff voltage of 3.3 V - deployed in automotive USB, HDMI, and CAN FD interface lines.
For engineers reviewing the PESD3V3T1BL-Q datasheet, PESD3V3T1BL-Q pinout, PESD3V3T1BL-Q application, or PESD3V3T1BL-Q equivalent, this page delivers verified electrical parameters, validated AEC-Q101 qualification status, SOD882 footprint layout guidance, and real-world interface protection use cases - all grounded in Nexperia's official 2023 product data sheet.
Technical Context
This device implements a symmetric bidirectional TVS structure with dual cathodes (K1/K2), enabling clamping for both positive and negative transients on a single line without polarity constraints. Its low dynamic resistance (0.12 Ω positive / 0.21 Ω negative, TLP 100 ns) ensures rapid voltage suppression during sub-ns ESD events.
It operates within a -55 °C to +150 °C ambient range and maintains <50 nA reverse leakage at 3.3 V, supporting high-impedance signal integrity in low-power automotive interfaces. The 20–25 pF capacitance at 0 V bias enables compatibility with high-speed data lines up to 480 Mbps (USB 2.0).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 3.3 V - Ensures no conduction during normal 3.3 V logic-level operation, preserving signal fidelity. |
| Clamping Voltage (VCL) | 9.3–11 V at 10 A (8/20 µs) - Limits transient voltage to safe levels for downstream 12 V-tolerant receivers. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact discharge - Meets automotive EMC requirements for infotainment and ADAS ports. |
| Peak Pulse Current (IPPM) | 10 A (8/20 µs) - Handles surge energy from lightning-induced coupling or load dump transients. |
| Diode Capacitance (Cd) | 20–25 pF at 1 MHz, 0 V - Low enough for USB 2.0 and I²C without signal rise-time degradation. |
| Dynamic Resistance (Rdyn) | 0.12 Ω (positive), 0.21 Ω (negative), TLP 100 ns - Enables fast clamping response under nanosecond-scale ESD pulses. |
| Leakage Current (IRM) | 0.1–50 nA at VRWM = 3.3 V - Prevents DC loading on high-impedance sensor or communication lines. |
Pinout & Package
DFN1006-2 (SOD882) ultra-small leadless plastic package: 1.0 mm × 0.6 mm × 0.48 mm body, 0.65 mm pitch, with transparent top view and marking band indicating cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |

| SOD882 footprint compatibility | Matches industry-standard DFN1006-2 land pattern (0.7 mm pad length, 0.3 mm width, 0.65 mm pitch), easing PCB layout reuse. |
| 30 kV ESD robustness | Exceeds ISO 10605 and IEC 61000-4-2 requirements for automotive electronics, reducing field failure risk. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
|
Use Scenario: Protecting USB 2.0 D+ and D− lines in automotive head units against hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at the USB connector, clamping ±8 kV ESD pulses before they reach the USB PHY. Use Value: Prevents latch-up or damage to USB transceivers while maintaining <1 ns response time and <25 pF loading for 480 Mbps signaling. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SCL/SDA) in vehicle infotainment displays from ESD during panel assembly and end-user handling. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on 5 V-tolerant I²C bus lines, positioned adjacent to HDMI receptacle to minimize loop inductance. Use Value: Enables compliance with HDMI 1.4a ESD immunity requirements without degrading 100 kHz I²C timing margins or increasing bus pull-up load. |
| CAN FD Transceiver Protection | Automotive Sensor Interface Protection |
|
Use Scenario: Shielding CAN FD high-speed (5 Mbps) differential pairs in ADAS domain controllers from ESD induced by chassis grounding mismatches or service port contact. IC Role / Device Role / Timing Role: Symmetric TVS diode across CAN_H and CAN_L, referenced to chassis ground, providing balanced clamping for common-mode and differential transients. Use Value: Maintains CAN FD signal edge integrity (tr < 1 ns) and avoids bit error rate increase due to added capacitance (<25 pF per line). |
Use Scenario: Protecting analog outputs of automotive pressure or temperature sensors (e.g., 0–5 V ratiometric signals) exposed to harness-level ESD during vehicle assembly or maintenance. IC Role / Device Role / Timing Role: Standoff-voltage-matched protector on sensor output line, placed between ADC input and connector to limit transient overvoltage to <11 V. Use Value: Preserves 12-bit ADC accuracy by limiting leakage current to <50 nA and avoiding offset drift from parasitic conduction during normal operation. |
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 NUP4201MR6T1G | Higher VRWM (5.0 V), higher Cd (35 pF), lower ESD rating (±15 kV), same SOD-523 package. | Not AEC-Q101 qualified; suitable for consumer-grade USB but not automotive CAN or HDMI. | Select only for cost-sensitive non-automotive designs where 5 V standoff and relaxed ESD margin are acceptable. |
| Vishay ESDE03-2 | Lower VRWM (3.0 V), identical Cd (25 pF), same ±30 kV ESD rating, but rated for only 6 A IPPM (8/20 µs). | Limited surge robustness makes it unsuitable for under-hood CAN FD or industrial Ethernet ports with coupled lightning surges. | Prefer only for space-constrained consumer audio interfaces where peak surge exposure is limited to ESD-only events. |
Compared with NUP4201MR6T1G and ESDE03-2, PESD3V3T1BL-Q uniquely combines AEC-Q101 qualification, 3.3 V standoff matching modern MCU I/O rails, 10 A surge capability, and 25 pF capacitance - making it the only option qualified for automotive USB 2.0, HDMI DDC, and CAN FD front-end protection in production vehicles.

FAQ
Is PESD3V3T1BL-Q compatible with reflow soldering per J-STD-020?
Yes. It is qualified for standard lead-free reflow profiles with peak temperatures up to 260 °C, matching JEDEC J-STD-020D. The DFN1006-2 package uses SnAgCu solder paste and requires a footprint per Figure 14 in the datasheet: 0.7 mm × 0.3 mm pads with 0.65 mm center-to-center spacing and thermal relief vias recommended for ground plane attachment.
What is the meaning of the 'L6' marking on the device top?
The 'L6' laser marking identifies the PESD3V3T1BL-Q variant per Nexperia's internal coding system and confirms authenticity. The black marking band adjacent to pin 1 indicates the cathode side, aligning with the K1 terminal designation in the pinning diagram - critical for correct orientation during placement.
Can this device protect a 5 V logic line?
No. With a 3.3 V reverse standoff voltage (VRWM), it begins conducting above ~4.7 V (typical VBR), risking false triggering on 5 V nominal lines. For 5 V interfaces, Nexperia recommends PESD5V0X1BL-Q (VRWM = 5.0 V) or similar higher-VRWM variants to avoid DC leakage and signal distortion.
How does its dynamic resistance affect clamping performance?
Its measured dynamic resistance of 0.12 Ω (positive) and 0.21 Ω (negative) under TLP 100 ns pulses directly determines voltage overshoot: VCL = VBR + IPP × Rdyn. This low Rdyn enables tighter clamping (e.g., 9.3 V at 10 A) versus alternatives with >0.5 Ω, reducing stress on downstream ICs during fast ESD events.
