Product details
Overview
PESD36VS1UJ from Nexperia is a unidirectional ESD protection diode in SOD323F (SC-90) package, rated for 36 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact discharge, 150 W peak pulse power, and 18–30 pF capacitance - deployed to safeguard single-ended signal lines in high-speed portable interfaces.
For engineers reviewing the PESD36VS1UJ datasheet, PESD36VS1UJ pinout, PESD36VS1UJ application, or PESD36VS1UJ equivalent, key selection criteria include clamping voltage at 2.5 A (≤80 V), ultra-low leakage (<1 nA at 36 V), dynamic resistance (9.5 Ω), and compact 1.7 mm × 1.25 mm footprint for space-constrained USB, audio, and antenna line protection.
Technical Context
This device operates as a unidirectional transient voltage suppressor optimized for low-capacitance signal integrity preservation. Its silicon avalanche structure delivers precise clamping at 80 V under 2.5 A (8/20 µs surge), with breakdown voltage tightly specified at 38.2–39.8 V (2 mA test current).
Designed for single-line protection where polarity relative to ground is fixed (positive or negative), it avoids bidirectional conduction path complexity while maintaining sub-1 nA reverse leakage at VRWM = 36 V - critical for battery-powered sensor and RF front-end circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line |
| Clamping Voltage | 80 V at IPP = 2.5 A - limits transient overvoltage seen by downstream IC during IEC 61000-4-5 surge events |
| Diode Capacitance | 18–30 pF at 1 MHz, 0 V - enables use on USB 2.0, HDMI, and audio lines without signal distortion |
| ESD Rating | ±30 kV contact discharge per IEC 61000-4-2 - exceeds Level 4 immunity requirements for handheld consumer devices |
| Peak Pulse Power | 150 W - sustains 2.5 A surge current (8/20 µs) without degradation in compact SOD323F package |
| Dynamic Resistance | 9.5 Ω - determines voltage overshoot during fast transients; lower value improves clamping response |
Pinout & Package
Package: SOD323F (SC-90), surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.7 mm with 2 leads and cathode-marked body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or reference node; marking bar on package identifies this terminal |
| 2 | Anode (A) | Connected to signal line requiring ESD protection; forward-biased during negative transients |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low leakage current | <1 nA at 36 V - minimizes standby power loss and prevents DC bias shift in high-impedance sensor inputs |
| Tight clamping performance | 80 V max at 2.5 A - ensures downstream logic-level ICs (e.g., 3.3 V or 5 V microcontrollers) remain within absolute maximum ratings |
| Low capacitance tolerance | 18–30 pF - maintains signal rise/fall time integrity on data lines up to 480 Mbps (USB 2.0) |
| Compact SOD323F footprint | 1.7 mm × 1.25 mm - enables placement directly at board edge connectors without routing detours |
Applications
| USB 2.0 Data Lines | Smartphone Audio Jacks |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 interfaces against ESD during cable insertion/removal and handling. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal trace and ground, activated only during positive transients on D+ or D−. Use Value: 18–30 pF capacitance preserves 480 Mbps data eye integrity; 80 V clamping prevents damage to USB transceiver PHY. | Use Scenario: Shielding 3.5 mm TRRS audio jack contacts (mic, left/right, ground) from user-handling ESD in smartphones and earbuds. IC Role / Device Role / Timing Role: Single-line protector per contact, oriented to clamp positive transients toward ground while blocking DC leakage. Use Value: Sub-1 nA leakage avoids microphone bias drift; 30 kV rating covers worst-case human-body-model discharge events. |
| RF Antenna Switch Paths | Industrial Sensor Signal Inputs |
Use Scenario: Guarding antenna switch control lines and RF front-end bias paths against ESD-induced latch-up in cellular modules. IC Role / Device Role / Timing Role: Low-capacitance shunt element on DC bias lines feeding GaAs or SOI switches, grounded via shortest possible path. Use Value: 9.5 Ω dynamic resistance ensures rapid clamping response (<1 ns), preventing gate oxide stress in sensitive RF switches. | Use Scenario: Securing analog input pins of 24-bit delta-sigma ADCs in industrial temperature or pressure sensors exposed to field wiring. IC Role / Device Role / Timing Role: First-stage transient suppressor on sensor output line, placed immediately after connector before RC filter network. Use Value: 36 V standoff matches common 24 V industrial supply rails; 150 W pulse rating handles induced surges from nearby relay switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC36AT3G | Higher VRWM (36 V), but larger SMC package (7.1 mm × 6.2 mm); 100 W PPPM; 100 pF Cd | Suitable for board-level surge (IEC 61000-4-5), not high-speed signal lines | Select when PCB space allows and higher surge energy handling is prioritized over capacitance |
| Vishay ESDBLE5.0D1W | Lower VRWM (5.0 V), bidirectional, 0.5 pF Cd, 30 kV ESD rating | Targeted at ultra-high-speed digital lines (e.g., PCIe Gen4, USB 3.2), not 36 V signal rails | Select only for low-voltage, bidirectional, ultra-low-C applications - not a functional substitute for 36 V unidirectional use |
Compared with SZ1.5SMC36AT3G and ESDBLE5.0D1W, PESD36VS1UJ uniquely balances 36 V standoff, 18–30 pF capacitance, and SOD323F size - making it optimal for compact, medium-voltage, unidirectional signal protection where both ESD robustness and signal fidelity matter.

FAQ
Is PESD36VS1UJ suitable for bidirectional signal lines like RS-485 or CAN?
No. PESD36VS1UJ is unidirectional and conducts only when anode voltage exceeds cathode by ≥38.2 V. Bidirectional lines require symmetrical clamping - use Nexperia's PESD5V0S1BA or similar dual-diode configurations instead.
What is the maximum recommended PCB trace length between PESD36VS1UJ and the protected connector?
Trace length should be ≤3 mm from diode cathode to ground plane and ≤2 mm from anode to protected line entry point. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond 80 V during fast ESD events.
Does PESD36VS1UJ meet automotive AEC-Q200 requirements?
No. Per Nexperia's revision history, PESD36VS1UJ was explicitly changed to non-automotive qualification in v.3 (2023). For automotive applications, select the -Q qualified variant PESD36VS1UJ-Q or equivalent AEC-Q200-compliant parts.
How does the 9.5 Ω dynamic resistance affect real-world clamping performance?
Dynamic resistance contributes directly to clamping voltage rise: VCL ≈ VBR + IPP × Rdyn. At 2.5 A, 9.5 Ω adds ~23.8 V above breakdown - consistent with the datasheet's 80 V max clamping (39 V typical VBR + 23.8 V = 62.8 V, well within margin). Lower Rdyn improves consistency across production lots.
