Product details
Overview
PESD3V3HS2-SF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small SMD package, designed to protect single signal lines against ±18 kV IEC 61000-4-2 contact discharge, with 0.8 pF capacitance, 4 V clamping voltage at 11 A, and reverse standoff voltage of ±3.3 V - used in high-speed data interfaces of portable electronics.
For engineers reviewing the PESD3V3HS2-SF datasheet, PESD3V3HS2-SF pinout, PESD3V3HS2-SF application, or PESD3V3HS2-SF equivalent, this page delivers verified electrical parameters, validated package dimensions, confirmed bidirectional clamping behavior, and real-world layout guidance for ESD-sensitive USB, HDMI, and audio signal paths.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling sub-4 V clamping during 8/20 µs transients up to 11 A while maintaining low leakage (<100 nA at 3.3 V) and minimal parasitic capacitance (0.8 pF typical).
Its dual-cathode configuration (Pins 1 and 2 both cathodes) supports symmetric bidirectional protection without polarity constraints, and its ultra-low inductance path ensures fast response to ESD events on high-frequency lines such as MIPI D-PHY and USB 2.0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | ±3.3 V - defines maximum continuous operating voltage before conduction begins on either polarity |
| Clamping Voltage | 4 V at 11 A (8/20 µs) - limits transient voltage seen by downstream ICs to safe logic-level thresholds |
| Diode Capacitance | 0.8 pF at 1 MHz - preserves signal integrity on >500 MHz data lines like USB 2.0 and HDMI DDC |
| ESD Rating | ±18 kV IEC 61000-4-2 contact - meets industrial and consumer immunity requirements without external filtering |
| Peak Pulse Current | 11 A (8/20 µs) - withstands high-energy surges from cable discharge events in handheld devices |
| Dynamic Resistance | 0.1 Ω (TLP, ±10 A) - enables rapid voltage collapse during ESD snap-back, minimizing energy dissipation time |
Pinout & Package
The PESD3V3HS2-SF is housed in a leadless DSN0603-2 (SOD962-2) package measuring 0.6 mm × 0.3 mm × 0.3 mm with 0.4 mm pitch; the marking bar indicates Pin 1 (K1), and both terminals are cathodes for symmetrical bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode | Common cathode connection; tied to ground reference for bidirectional clamping path |
| 2 (K2) | Cathode | Second cathode terminal; electrically identical to Pin 1, enabling symmetric layout routing |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Equal ±3.3 V standoff and ±4 V clamping ensures no polarity bias on AC-coupled or differential lines |
| Ultra-Low Capacitance | 0.8 pF minimizes insertion loss and phase distortion on 480 Mbps USB 2.0 and 1.5 Gbps HDMI signals |
| Snap-Back Structure | Negative dynamic resistance reduces clamping voltage under surge, lowering stress on protected SoCs |
| High Surge Robustness | 11 A 8/20 µs rating supports repeated ESD strikes without parameter shift or failure |
Applications
| Smartphone Antenna Switching | USB-C Audio Adapters |
|---|---|
Use Scenario: Protecting RF antenna switch control lines from ESD during user handling and connector mating. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed directly at SMA connector interface.

IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on unidirectional analog line with ground-referenced return path. Use Value: 4 V clamping prevents op-amp input stage latch-up; DSN0603-2 footprint fits tight space behind USB-C receptacle. |

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 capacitance (12 pF), lower clamping (3.3 V), quad-channel configuration | Requires PCB area for 4-line protection; unsuitable for single-line space-constrained layouts | Select when protecting multiple adjacent lines with shared ground and higher capacitance tolerance |
| Vishay VEML3020-001 | Unidirectional, 5.5 V standoff, 0.5 pF capacitance, ±30 kV ESD rating | Lacks bidirectional symmetry; requires polarity-aware placement and separate ground paths per line | Choose only for DC-biased lines where polarity is fixed and ultra-low capacitance is critical |
Compared with NUP4105MR6T1G and VEML3020-001, the PESD3V3HS2-SF uniquely balances ultra-low capacitance (0.8 pF), true bidirectionality, and compact two-terminal DSN0603-2 packaging - making it optimal for single-line, space-limited, AC-coupled interfaces like USB 2.0 D+ and D−.

FAQ
What is the maximum recommended PCB trace length between PESD3V3HS2-SF and the protected connector?
The datasheet specifies that the transient return path to ground must be minimized; for optimal ESD suppression, keep the distance from the device to the connector ≤2 mm and use a direct, low-inductance ground via within 1 mm of Pin 1 or Pin 2 - longer traces degrade clamping performance above 1 GHz.
Can PESD3V3HS2-SF be used on a 5 V logic line?
No - its ±3.3 V reverse standoff voltage means sustained operation above ±3.3 V risks premature conduction and thermal runaway; it is intended only for 3.3 V or lower nominal signal lines such as USB 2.0, MIPI D-PHY, or HDMI DDC, not 5 V GPIO or UART.
Does the device require external biasing or control signals?
No - PESD3V3HS2-SF is a passive, two-terminal device with no enable pin, bias rail, or control interface; it operates solely through avalanche breakdown and snap-back conduction triggered by overvoltage events, requiring zero external circuitry.
How does the dual-cathode configuration affect PCB layout?
Both pins are cathodes and internally shorted; they may be routed independently to separate ground vias or joined into a single low-inductance ground net - the key is ensuring equal-length, symmetric traces to avoid impedance imbalance that could skew clamping symmetry during fast transients.
