Product details
Overview
PESD12VS1UA-Q from Nexperia is a unidirectional ESD protection diode in SOD323 package, designed to safeguard single signal lines against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (22.5 A, 8/20 µs). It features 12 V reverse standoff voltage, 27 V clamping at 22.5 A, and 160–180 pF capacitance - ideal for high-speed USB, HDMI, or automotive infotainment data lines.
For engineers reviewing the PESD12VS1UA-Q datasheet, PESD12VS1UA-Q pinout, PESD12VS1UA-Q application, or PESD12VS1UA-Q equivalent, key selection criteria include clamping voltage under 22.5 A surge, sub-200 pF capacitance for signal integrity, AEC-Q101 qualification for automotive use, and cathode-anode polarity alignment in compact SOD323 layout.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below 12 V reverse standoff (VRWM), breaks down at 13.3–15.75 V (VBR @ 5 mA), and clamps transients to ≤27 V at 22.5 A peak pulse current. Its low 1 nA leakage at 12 V ensures minimal loading on sensitive analog or digital signal paths.
The device uses silicon PN-junction architecture with differential resistance of 5–100 Ω, enabling fast response (<1 ns rise time per IEC 61000-4-2) and stable clamping across temperature. Thermal resistance junction-to-solder point is 90 K/W, supporting reliable operation up to 150 °C junction temperature in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V reverse standoff voltage - defines maximum continuous operating voltage before conduction begins. |
| VBR | 13.3–15.75 V breakdown voltage at 5 mA - ensures predictable turn-on during overvoltage events. |
| VCL | 27 V clamping voltage at 22.5 A (8/20 µs) - limits downstream IC stress during IEC 61000-4-5 surges. |
| Cd | 160–180 pF capacitance at 1 MHz, 0 V - preserves signal integrity on high-speed interfaces like USB 2.0. |
| IPP | 22.5 A peak pulse current (IEC 61000-4-5) - withstands automotive-level lightning-induced transients. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial and automotive ESD immunity requirements. |
| IRM | 1 nA max reverse leakage at 12 V - avoids DC bias shift or power loss in battery-powered systems. |
Pinout & Package
Package: SOD323 - surface-mounted plastic package, 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch. Marking band indicates cathode (Pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode | Connected to protected line; conducts transient current to ground when forward-biased by positive overvoltage. |
| 2 (A) | Anode | Connected to system ground; completes shunt path during ESD/surge events on unidirectional positive-polarity signals. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, infotainment, and ADAS sensor interfaces. |
| 600 W peak pulse power | Handles high-energy transients without degradation - supports robust design margin in harsh environments. |
| Low 160–180 pF capacitance | Minimizes signal distortion on 480 Mbps USB 2.0 or 720p video lines without requiring impedance tuning. |
| 1 nA reverse leakage | Enables use in ultra-low-power IoT sensors and always-on automotive modules without battery drain. |
| Cathode-marked SOD323 | Ensures correct orientation during automated placement - critical for unidirectional protection functionality. |
Applications
| Automotive Infotainment | USB 2.0 Data Lines |
|---|---|
|

| Medical Sensor Interfaces | Industrial CAN FD Transceivers |
|
Use Scenario: Shielding analog front-end inputs of portable ECG or pulse oximeter devices from handling ESD. IC Role / Device Role: Low-leakage (1 nA) protector on biopotential signal paths to preserve DC accuracy. Use Value: Prevents baseline shift or amplifier saturation during clinical handling without adding noise or offset. |
Use Scenario: Adding secondary ESD protection on CAN_H/CAN_L lines upstream of AEC-Q100-compliant transceivers.

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 NUP4105MR6T1G | Higher 33 V clamping at 24 A; 30 pF lower capacitance (130–150 pF); same SOD-323 package. | Better suited for lower-capacitance USB 3.0 Gen1 lanes but less effective for 12 V rail protection due to higher VBR (15.5 V min). | Select when signal bandwidth > 500 MHz and VRWM margin allows ≥15 V standoff. |
| Vishay VEML3020X01 | Lower 20 V clamping at 20 A; 220 pF capacitance; AEC-Q101 qualified; same footprint. | Higher capacitance limits use to <100 Mbps interfaces; tighter clamping benefits 3.3 V logic protection. | Prefer for cost-sensitive 12 V automotive body electronics where speed is secondary to clamping performance. |
Compared with NUP4105MR6T1G and VEML3020X01, PESD12VS1UA-Q delivers optimal balance of 12 V VRWM compatibility, 27 V clamping, and 160–180 pF for USB 2.0 and infotainment links - making it the default choice for AEC-Q101-compliant 12 V signal-line protection.

FAQ
What is the maximum operating temperature for PESD12VS1UA-Q?
The PESD12VS1UA-Q supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to 150 °C. Its thermal resistance junction-to-solder point is 90 K/W, enabling reliable operation in under-hood automotive environments when mounted per recommended PCB footprint.
Can PESD12VS1UA-Q protect bidirectional signal lines?
No - PESD12VS1UA-Q is unidirectional and protects only positive-polarity transients relative to ground. For bidirectional lines such as USB D+/D− or RS-485, a dual-diode array like PESD5V0S1BA-Q is required to clamp both polarities.
How does the 1 nA leakage current impact low-power designs?
At 1 nA maximum reverse leakage (IRM) under 12 V VRWM, the device adds negligible current draw - less than 0.1 µW power loss - making it suitable for always-on battery-powered sensors, wearables, and automotive wake-up circuits without compromising standby life.
Is the SOD323 footprint compatible with standard reflow profiles?
Yes - Nexperia specifies a standard reflow soldering footprint for SOD323 (Figure 11), with 0.5 mm pad width and 1.5 mm pad length. The device complies with JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for 30 seconds.
