Product details
Overview
PESD1V2Y1BSF 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 IEC 61000-4-2 Level 4 ESD events. It delivers 0.26 pF typical capacitance, 1.2 V reverse standoff voltage, and 3.4 V TLP trigger voltage for high-speed interfaces including USB 3.2 data lines.
For engineers reviewing the PESD1V2Y1BSF datasheet, PESD1V2Y1BSF pinout, PESD1V2Y1BSF application, or PESD1V2Y1BSF equivalent, key selection criteria include clamping voltage under 8 A TLP, sub-1 nA leakage at 1.2 V, cathode-to-cathode dual-terminal configuration, and placement between AC coupling capacitors and transceivers in high-frequency signal paths.
Technical Context
This device employs a snap-back clamping structure with negative dynamic resistance, enabling low-voltage triggering (Vt1 = 3.4 V TLP) and reduced clamping during ESD transients. Its bidirectional operation supports signal lines with both positive and negative polarity relative to ground.
The ultra-low inductance path to ground and 0.26 pF capacitance preserve signal integrity on high-speed lines up to 10 Gbps. The DSN0603-2 package's 0.4 mm pitch and 0.6 mm × 0.3 mm footprint minimize PCB trace inductance and parasitic coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | ±1.2 V - Ensures no conduction during normal operation of low-voltage I/O such as USB 3.2 Gen 1/2 receivers. |
| Diode Capacitance | 0.26 pF typ. at 1 MHz, 0 V - Enables minimal signal distortion on >5 Gbps differential links without equalization overhead. |
| TLP Trigger Voltage | 3.4 V at 100 ns pulse - Activates clamping before sensitive transceiver input stages exceed absolute maximum ratings. |
| Clamping Voltage | <8.5 V at 8 A TLP - Limits transient overvoltage to levels compatible with 1.2 V I/O rail tolerance. |
| Leakage Current | <1 nA typ. at 1.2 V - Prevents DC loading and bias shift in precision analog or low-power sensor interfaces. |
| Package | DSN0603-2 (SOD962-2), 0.6 mm × 0.3 mm × 0.3 mm - Supports ultra-dense routing near board edges and connectors. |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, two-terminal surface-mount package with cathode-marked top side. Body dimensions are 0.6 mm × 0.3 mm × 0.3 mm, pitch is 0.4 mm, and terminals are co-planar solder pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode | Connected to protected signal line; forms one half of symmetrical bidirectional clamping path. |
| 2 (K2) | Cathode | Connected to system ground; completes low-inductance transient return path during ESD event. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Protects AC-coupled lines with ± polarity swings without polarity-sensitive placement. |
| Snap-back dynamic resistance | Reduces clamping voltage by >40% vs. standard TVS during 8 A TLP pulses. |
| Ultra-low capacitance | 0.26 pF preserves signal rise/fall times and eye diagram integrity on USB 3.2 Gen 2 lanes. |
| Sub-1 nA leakage at VRWM | Eliminates measurable DC offset in high-impedance sensor or reference voltage nodes. |
Applications
| USB 3.2 Gen 1/2 Data Lines | High-Speed HDMI Interface |

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 ESDE0402E01200 | 0.35 pF capacitance, 1.2 V VRWM, 3.8 V TLP trigger | Higher clamping voltage (9.2 V @ 8 A) limits use in 1.2 V rail systems | Prefer when board layout allows slightly higher capacitance and system tolerates +0.7 V clamping margin. |
| Vishay VEML6030X01 | 0.22 pF capacitance but unidirectional; requires dual-device implementation | Not suitable for true bidirectional lines without added series components | Select only if signal polarity is fixed and space permits two devices per line. |
Compared with ESDE0402E01200 and VEML6030X01, PESD1V2Y1BSF uniquely combines true bidirectionality, 0.26 pF capacitance, and sub-8.5 V clamping in a single 0.6 mm × 0.3 mm device-enabling direct replacement in USB 3.2 and HDMI 2.0+ layouts without redesign.

FAQ
What is the maximum recommended trace length between PESD1V2Y1BSF and the protected connector?
Maximum recommended PCB trace length from the device to the connector is 2 mm. Longer traces increase inductance and degrade clamping performance during 15 kV ESD events. Placement must follow the "as close as possible" rule per Figure 1 in the short data sheet, with ground return path minimized using multiple vias to inner ground planes.
Can PESD1V2Y1BSF be used on 3.3 V I/O lines?
No-PESD1V2Y1BSF has a 1.2 V reverse standoff voltage and is rated only for systems where the signal swing remains within ±1.2 V of ground. Using it on 3.3 V lines risks permanent conduction due to exceeding VRWM, leading to increased leakage and potential thermal failure. Select PESD5V0Y1BSF for 3.3 V applications.
Does PESD1V2Y1BSF require external series impedance for proper snap-back operation?
No external series resistor is required. The device's intrinsic snap-back behavior activates reliably at 3.4 V TLP without added current limiting. However, system-level series impedance (e.g., PCB trace resistance or driver output impedance) must remain below 5 Ω to ensure full clamping voltage compliance under 8 A TLP conditions.
Is reflow profile compatibility documented for the DSN0603-2 package?
Yes-the official Nexperia footprint and reflow guidelines specify a recommended stencil thickness of 0.1 mm, solder paste volume control, and peak reflow temperature of 260 °C for 10 seconds. Figure 3 in the short data sheet provides exact land pattern dimensions: 0.256 mm × 0.256 mm pads with 0.4 mm center-to-center spacing.
