Product details
Overview
PESD3V3T1BLD from Nexperia is a bidirectional ESD protection diode designed to safeguard one signal line against electrostatic discharge (ESD) up to 30 kV (IEC 61000-4-2 contact) and surge transients (8/20 µs, IPP = 10 A). It features a 3.3 V reverse standoff voltage (VRWM), 9.3–11 V clamping voltage at 10 A, and ultra-low 20–25 pF capacitance - enabling high-speed interface protection in space-constrained applications such as USB 2.0 or I²C lines.
For engineers reviewing the PESD3V3T1BLD datasheet, PESD3V3T1BLD pinout, PESD3V3T1BLD application, or PESD3V3T1BLD equivalent, this device delivers verified bidirectional clamping performance, side-wettable flanks for automated optical inspection (AOI), and precise low-capacitance transient suppression critical for signal integrity in portable and industrial electronics.
Technical Context
This diode operates symmetrically across both polarities, with breakdown voltage (VBR) of 4.7–8.7 V at 5 mA and dynamic resistance (Rdyn) of 0.12 Ω (positive) / 0.21 Ω (negative) under TLP conditions. Its bidirectional architecture eliminates polarity dependency, making it suitable for AC-coupled or dual-rail data lines.
The SOD882D (DFN1006D-2) package enables placement within 1 mm of connectors, minimizing inductance in the transient path. With IRM ≤ 50 nA at 3.3 V and junction temperature rated to 150 °C, it supports robust operation in extended ambient environments without thermal derating concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - ensures no leakage or conduction during normal 3.3 V signal operation. |
| VCL @ 10 A | 9.3–11 V clamping voltage (8/20 µs) - limits transient voltage to safe levels for downstream ICs. |
| IPP | 10 A peak pulse current (8/20 µs) - withstands IEC 61000-4-5 surge events without failure. |
| Cd | 20–25 pF capacitance at 1 MHz, 0 V - preserves signal integrity on high-speed interfaces like USB 2.0. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - exceeds industrial ESD immunity requirements. |
| Rdyn | 0.12 Ω (positive), 0.21 Ω (negative) - ensures fast, low-impedance clamping response to fast transients. |
Pinout & Package

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 VRWM (5.0 V), higher Cd (35 pF), larger SOT-563 package (2.2 × 1.35 mm). | Less suitable for 3.3 V high-speed lines due to higher capacitance and voltage margin. | Select when higher standoff voltage is required and board space allows larger footprint. |
| Vishay VEML6030X01 | Not applicable - this is an ambient light sensor, not an ESD diode; excluded from valid alternatives. | N/A | Not a functional alternative; invalid cross-reference. |
Compared with NUP4105MR6T1G, PESD3V3T1BLD offers tighter 3.3 V standoff matching, 40% lower capacitance, and 55% smaller footprint - making it superior for compact, high-speed 3.3 V interfaces where signal fidelity and layout density are critical.

FAQ
What is the maximum operating temperature for PESD3V3T1BLD?
The PESD3V3T1BLD has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. This allows deployment in uncooled industrial enclosures and automotive-adjacent environments without thermal derating, provided PCB copper area and layout follow Nexperia's recommended thermal guidelines.
Does PESD3V3T1BLD require external biasing or control signals?
No. PESD3V3T1BLD is a passive, bidirectional Zener-like clamp with no power supply, enable pin, or control logic. It operates automatically during overvoltage events, conducting only when line voltage exceeds its breakdown threshold (4.7–8.7 V), and remains fully transparent during normal 3.3 V signal operation.
How does the side-wettable flank design aid manufacturing?
The SOD882D package's side-wettable flanks allow automated optical inspection (AOI) systems to verify solder fillet formation on the 0.65 mm pitch terminals - eliminating reliance on X-ray for process validation and reducing post-reflow defect escape in high-volume SMT lines.
Can PESD3V3T1BLD protect against IEC 61000-4-5 surges?
Yes. It is rated for 10 A peak pulse current (IPPM) under the 8/20 µs waveform per IEC 61000-4-5, with typical clamping voltage of 9.3–11 V. This provides validated protection for Level 3 (1 kV) and Level 4 (2 kV) surge immunity testing when placed within 2 mm of the connector per layout best practices.
