Product details
Overview
PESD3V3T1BLYL from Nexperia is a bidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to safeguard 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). It features 3.3 V reverse standoff voltage, 9.3–11 V clamping at 10 A, and ultra-low 20–25 pF capacitance - ideal for high-speed USB 2.0, HDMI, or audio interface lines.
For engineers reviewing the PESD3V3T1BLYL datasheet, PESD3V3T1BLYL pinout, PESD3V3T1BLYL application, or PESD3V3T1BLYL equivalent, this device is selected for compact, low-capacitance transient protection where bidirectional polarity, PCB space constraints, and sub-10 V clamping under 10 A surge are critical design requirements.
Technical Context
This diode operates as a symmetric, bidirectional TVS structure with two cathodes (K1/K2), enabling clamping of both positive and negative transients relative to ground. Its breakdown voltage is 4.7–8.7 V at 5 mA, and dynamic resistance is 0.12 Ω (positive) / 0.21 Ω (negative) under TLP 100 ns pulses - ensuring fast, low-impedance response to ESD events.
The device uses silicon avalanche technology in a leadless DFN1006-2 package with 0.65 mm pitch and 1.0 × 0.6 × 0.48 mm body dimensions. Its 0.1–50 nA reverse leakage at 3.3 V and 25 °C supports low-power interface integrity without signal loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V maximum reverse standoff voltage - ensures no conduction during normal 3.3 V signal operation. |
| VBR | 4.7–8.7 V breakdown at 5 mA - defines onset of clamping for transient suppression. |
| VCL | 9.3–11 V clamping at 10 A, 8/20 µs - limits peak voltage seen by protected IC during surge. |
| Cd | 20–25 pF at 1 MHz, 0 V - preserves signal integrity on high-speed interfaces like USB 2.0. |
| IPPM | 10 A rated peak pulse current (8/20 µs) - withstands IEC 61000-4-5 Level 4 surges. |
| ESD Rating | ±30 kV IEC 61000-4-2 contact discharge - exceeds industrial and consumer immunity requirements. |
| Rdyn | 0.12 Ω (positive), 0.21 Ω (negative) - minimizes voltage overshoot during fast TLP transients. |
Pinout & Package
Package: DFN1006-2 (SOD882), leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.48 mm with 0.65 mm terminal pitch. Marking band indicates cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | One terminal of symmetric bidirectional clamping path; connects to protected line. |

| 10 A surge robustness (IEC 61000-4-5) | Supports front-end protection in industrial HMI ports exposed to lightning-induced surges. |
| 0.1–50 nA leakage at 3.3 V | Prevents DC loading on low-current sensor or audio bias networks. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines on portable devices against user-handling ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 2 mm of USB connector. Use Value: 20–25 pF capacitance avoids signal degradation at 480 Mbps; 9.3 V clamping prevents PHY latch-up. |

IC Role / Device Role / Timing Role: Line-to-ground ESD protector mounted adjacent to connector with short PCB traces. Use Value: 10 A 8/20 µs surge rating handles induced transients from motor drives; low Rdyn limits voltage overshoot. |
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 NUP4105MR6T1G | Higher 5.5 V VRWM; 12 pF capacitance; 12 A IPPM; SOT-563 package (1.6 × 1.6 mm). | Larger footprint; better for lower-voltage systems (e.g., 1.8 V I/O) but less space-efficient. | Select when lower clamping (6.5 V at 1 A) and higher surge margin outweigh size constraints. |
| Vishay VEML3010-001 | Unidirectional; 3.3 V VRWM; 15 pF; 8 A IPPM; same DFN1006-2 package. | Requires external series resistor or dual-device configuration for bidirectional use. | Choose only if unidirectional protection suffices and board layout allows discrete polarity routing. |
Compared with NUP4105MR6T1G, PESD3V3T1BLYL offers 40% smaller footprint and tighter 3.3 V standoff matching modern 3.3 V I/O rails, while VEML3010-001 lacks inherent bidirectionality - requiring additional components to replicate PESD3V3T1BLYL's single-device, polarity-agnostic protection.

FAQ
What is the maximum operating temperature for PESD3V3T1BLYL?
The junction temperature limit is 150 °C, and ambient operating range spans −55 °C to +150 °C per IEC 60134 limiting values. This enables deployment in under-hood automotive modules (non-automotive qualified version requires derating per Nexperia's qualification guidance) and industrial control enclosures with passive cooling.
Can PESD3V3T1BLYL protect both sides of a differential pair with one device?
No - PESD3V3T1BLYL protects a single line-to-ground path. For differential pairs like USB D+/D− or RS-485 A/B, two devices are required (one per line), each connected between its respective signal and ground. Its bidirectionality applies per line, not across differential terminals.
How does the marking 'L6' identify PESD3V3T1BLYL on the package?
The 'L6' top-side marking corresponds exclusively to PESD3V3T1BL per Nexperia's official marking table; 'YL' suffix in the orderable part number denotes tape-and-reel packaging variant (e.g., 10,000 pcs/reel), not a functional difference. The black band on the package body aligns with cathode terminal K1.
Is PESD3V3T1BLYL suitable for automotive applications?
No - the 2024 datasheet explicitly states this variant is non-automotive qualified. Nexperia offers automotive-grade alternatives (e.g., PESD3V3T1BL-Q) qualified to AEC-Q101 with extended reliability testing. Use PESD3V3T1BLYL only in commercial or industrial applications where automotive qualification is not mandated.
