Product details
Overview
PESD36VS1UJ-Q 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, 2.5 A peak pulse current (8/20 µs), 150 W peak pulse power, and <1 nA reverse leakage at 36 V - deployed on high-speed signal lines in automotive infotainment interfaces.
For engineers reviewing the PESD36VS1UJ-Q datasheet, PESD36VS1UJ-Q pinout, PESD36VS1UJ-Q application, or PESD36VS1UJ-Q equivalent, this page delivers verified electrical specs, validated automotive qualification status (AEC-Q101), real-world clamping behavior (80 V at 2.5 A), and layout-critical placement guidance for ESD-sensitive USB, HDMI, and CAN FD data paths.
Technical Context
This device operates as a single-line unidirectional TVS diode with avalanche breakdown at 39 V (typical), clamping to ≤80 V under 2.5 A transient stress, and dynamic resistance of 9.5 Ω - enabling fast response (<1 ns rise time per IEC 61000-4-2) while maintaining low capacitive loading (18–30 pF at 0 V).
Its SOD323F footprint supports compact routing near connectors, and its AEC-Q101 qualification confirms operation across −55 °C to +150 °C junction temperature, with thermal derating curves defined for pulse durations from 100 ns to 10 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - maximum continuous DC or RMS signal voltage the line can carry without diode conduction |
| Clamping Voltage | 80 V at 2.5 A (8/20 µs) - limits transient overvoltage seen by downstream ICs during surge events |
| Peak Pulse Power | 150 W - sustains 2.5 A surges without failure under standardized IEC 61000-4-5 waveform |
| Diode Capacitance | 18–30 pF at 1 MHz / 0 V - preserves signal integrity on high-speed lines (e.g., USB 2.0, audio codecs) |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - exceeds Level 4 immunity requirements for automotive ECUs |
| Leakage Current | <1 nA at 36 V - avoids DC loading on precision analog or battery-backed signal paths |
| Breakdown Voltage | 39 V (typical) at 2 mA - ensures reliable turn-on before protected IC's absolute maximum rating is exceeded |
Pinout & Package
Package: SOD323F (SC-90), surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.7 mm; cathode indicated by marking bar on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground; conducts transient current from protected line to GND when voltage exceeds VRWM |
| 2 (A) | Anode | Connected to signal line requiring protection; blocks reverse current below 36 V, avalanches above 39 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including engine control, ADAS sensors, and infotainment displays |
| Ultra-low capacitance | 18–30 pF enables deployment on 480 Mbps USB 2.0 and 25 MHz audio I²S buses without signal degradation |
| Low dynamic resistance | 9.5 Ω minimizes voltage overshoot during fast transients, improving clamping accuracy |
| Marking bar identification | Visible cathode indicator simplifies automated optical inspection (AOI) and manual assembly verification |
| Reflow-compatible footprint | SOD323F land pattern supports standard lead-free reflow profiles per J-STD-020 |
Applications
| Automotive Infotainment Display Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LVDS or FPD-Link II video data lines between head unit and TFT display in vehicles exposed to ESD during service or user interaction. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed at display connector to shunt ESD pulses directly to chassis ground before reaching timing controller IC. Use Value: Prevents latch-up or gate oxide damage in display driver ICs while adding only 25 pF loading to 100+ MHz pixel clock signals. |
Use Scenario: Safeguarding D+ and D− lines of USB 2.0 ports in telematics control units against hot-plug ESD and cable-induced surges. IC Role / Device Role / Timing Role: Single-line ESD suppressor mounted adjacent to USB receptacle, conducting transients within 1 ns of onset. Use Value: Maintains eye diagram integrity at 480 Mbps by limiting capacitance to ≤30 pF and clamping to ≤80 V at 2.5 A. |
| Automotive CAN FD Transceiver Interface | Portable Audio Codec Signal Path |
Use Scenario: Shielding CAN FD high-speed (5 Mbps) differential bus lines in ADAS domain controllers from ESD coupling via harness connectors. IC Role / Device Role / Timing Role: Discrete unidirectional TVS on CANH line referenced to vehicle ground, sized to handle ±30 kV contact discharge without degrading common-mode rejection. Use Value: Ensures CAN FD bit error rate remains <10⁻¹² after repeated ESD stress, with no impact on 5 Mbps signal edge rates. |
Use Scenario: Protecting analog audio input/output lines (e.g., headset jack, microphone bias) in Bluetooth earbuds against user-handling ESD. IC Role / Device Role / Timing Role: Low-leakage (≤1 nA) ESD clamp on biased audio path, preventing DC offset shift or pop-noise during transient events. Use Value: Eliminates audible click/pop artifacts during ESD events while preserving SNR >105 dB in 20 Hz–20 kHz band. |
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 pF capacitance, 1500 W PPPM | Suitable for board-level surge (IEC 61000-4-5 Level 4), not high-speed signal lines | Select when protecting power rails or low-frequency sensor lines where size and capacitance are secondary |
| Vishay ESDBLE36-2 | Same SOD323F package, 36 V VRWM, but bidirectional configuration and 22 pF typical capacitance | Required for AC-coupled or dual-polarity signal paths (e.g., RS-485, audio differential pairs) | Choose only if signal polarity reverses relative to ground; otherwise PESD36VS1UJ-Q offers lower leakage and tighter clamping |
Compared with SZ1.5SMC36AT3G and ESDBLE36-2, PESD36VS1UJ-Q uniquely balances ultra-low capacitance (18–30 pF), automotive qualification, and compact SOD323F footprint - making it optimal for space-constrained, high-speed unidirectional data lines where leakage and layout density are critical.

FAQ
What is the maximum operating temperature for PESD36VS1UJ-Q?
The device supports junction temperatures up to +150 °C and ambient storage from −65 °C to +150 °C, with full AEC-Q101 qualification confirming reliability across automotive under-hood and cabin environments.
Can PESD36VS1UJ-Q protect bidirectional signal lines like RS-232?
No - it is unidirectional and designed only for signals with fixed polarity relative to ground. For bidirectional lines, use a symmetric device such as Vishay ESDBLE36-2 or Nexperia PESD5V0S1BA.
How does the 9.5 Ω dynamic resistance affect clamping performance?
This value determines voltage overshoot during fast transients: VCL = VBR + IPP × RDYN. At 2.5 A, it contributes ~24 V of resistive drop, explaining why clamping reaches 80 V despite 39 V breakdown.
Is the SOD323F footprint compatible with automated optical inspection (AOI)?
Yes - the cathode marking bar is clearly visible under standard AOI lighting, and the 1.7 mm × 1.25 mm body meets IPC-A-610 Class 3 solder joint inspection criteria for fine-pitch SMT assemblies.
