Product details
Overview
PESD15VL2BT-Q from Nexperia is a low-capacitance, double bidirectional ESD protection diode in SOT23 package, designed to protect two signal lines against ±30 kV IEC 61000-4-2 ESD strikes and 5 A surge pulses per IEC 61000-4-5. It delivers 16 pF capacitance at 0 V, 44 V clamping voltage at 5 A, and 1 nA leakage at 15 V, enabling high-speed interface protection in automotive infotainment and portable USB/SD card interfaces.
For engineers reviewing the PESD15VL2BT-Q datasheet, PESD15VL2BT-Q pinout, PESD15VL2BT-Q application, or PESD15VL2BT-Q equivalent, key selection criteria include bidirectional clamping symmetry, sub-20 pF signal-line loading, AEC-Q101 qualification, and dual-cathode SOT23 layout compatibility with space-constrained PCBs.
Technical Context
This device implements a symmetric dual-cathode TVS structure with matched breakdown voltages (17.1–20.3 V) across both channels, enabling true bidirectional transient suppression on differential or single-ended lines referenced above/below ground. Its 225 Ω differential resistance ensures fast response without signal distortion.
Clamping performance is validated under standardized 8/20 µs surge (5 A) and 150 pF/330 Ω ESD (±30 kV) waveforms, with thermal derating confirmed up to 150 °C junction temperature. The SOT23 footprint supports automated placement and reflow while maintaining low-inductance paths for effective transient shunting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected lines. |
| Clamping Voltage | 44 V at 5 A - Peak voltage seen by downstream circuit during worst-case 8/20 µs surge; limits stress on IC inputs. |
| Diode Capacitance | 16 pF at 1 MHz, 0 V - Low signal-line loading enables use on USB 2.0, HDMI, SDIO, and other >10 MHz interfaces without bandwidth loss. |
| ESD Rating | ±30 kV contact discharge per IEC 61000-4-2 Level 4 - Full immunity to human-body ESD events in handheld and automotive environments. |
| Leakage Current | 1 nA at 15 V - Negligible DC loading on high-impedance sensor or audio bias networks; avoids signal offset or battery drain. |
| Peak Pulse Power | 200 W - Sustained energy handling capability for transient suppression without thermal runaway under repeated surges. |
| Breakdown Voltage | 18.8 V typical at 5 mA - Tight tolerance (±1.7 V) ensures predictable turn-on and consistent protection margin across production lots. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm), 3-terminal, 1.9 mm pitch; qualified per AEC-Q101 for automotive under-hood and cabin applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | First cathode terminal - connects to first protected signal line; forms one half of symmetrical bidirectional clamp path. |
| 2 | K2 | Second cathode terminal - connects to second protected signal line; enables independent or differential protection of two lines. |
| 3 | CC | Common cathode - tied internally to both K1 and K2; serves as shared return path to system ground for transient current. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line bidirectional ESD protection | Single SOT23 device protects two independent signal paths with matched clamping behavior and no polarity constraints. |
| Ultra-low 16 pF capacitance | Preserves signal integrity on high-speed interfaces (e.g., USB 2.0, SD card, I²C) without requiring trace-length compensation. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock - suitable for infotainment and ADAS modules. |
| 1 nA reverse leakage | Enables use on battery-powered sensor nodes and analog front-ends where microamp-level current budgets are critical. |
| 44 V clamping at 5 A | Provides robust surge margin for industrial and automotive systems exposed to load-dump or inductive switching transients. |
Applications
| USB 2.0 Port Protection | Automotive Infotainment Display Interface |
|---|---|

Use Value: Achieves 30 kV contact ESD immunity without compromising 1.8 V SIM interface timing margins or increasing standby current. |
Use Scenario: Protecting SDIO command, clock, and data lines in ruggedized medical or test equipment where electrostatic buildup occurs during operator interaction. IC Role / Device Role / Timing Role: Low-capacitance ESD guard on all six SDIO signals, placed within 2 mm of edge connector to minimize inductance. Use Value: Maintains 25 MHz SDIO timing compliance while surviving 5 A surge pulses induced by nearby relay switching or motor drives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher capacitance (30 pF), lower clamping (33 V at 5 A), same SOT23-3 package but asymmetric pinout (K1/K2/ANODE). | Better for low-voltage logic (≤3.3 V) but unsuitable for 5 V or high-speed interfaces due to excessive signal loading. | Select when clamping voltage priority outweighs bandwidth; verify PCB layout accommodates reversed anode/cathode orientation. |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, not an ESD protector; excluded from valid alternatives. | N/A - incorrect device category; cannot substitute for transient suppression function. | Discard immediately; this is a misidentified part with no functional overlap. |
Compared with NUP4202MR6T1G, PESD15VL2BT-Q offers 47% lower capacitance for high-frequency signal integrity, tighter clamping voltage control, and AEC-Q101 qualification - making it preferred for automotive and USB 2.0 applications where speed and reliability are co-critical.

FAQ
What is the maximum working voltage this diode can protect?
The PESD15VL2BT-Q has a reverse standoff voltage (VRWM) of 15 V, meaning it remains non-conductive up to this DC or peak AC voltage. Operation above 15 V risks premature conduction and potential damage to protected circuits. It is rated for 17.1–20.3 V breakdown, ensuring reliable margin before clamping activates.
Can this device protect differential signal pairs like USB D+/D−?
Yes - its symmetric bidirectional structure allows direct connection across D+ and D− with CC grounded, or individually on each line with separate CC-to-ground connections. The matched 16 pF capacitance and <1.7 V breakdown tolerance preserve differential impedance and eye diagram integrity at USB 2.0 speeds.
Is the SOT23 footprint compatible with standard reflow profiles?
Yes - the device is qualified for lead-free reflow per J-STD-020, with a maximum peak temperature of 260 °C. The recommended solder land pattern matches JEDEC MO-203-1 (SOT23), and thermal performance is validated up to 150 °C junction temperature under sustained 200 W pulse loads.
Does this part meet automotive EMC requirements beyond ESD?
It satisfies IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity standards, and its AEC-Q101 qualification covers temperature cycling, humidity, and mechanical stress. While not itself an EMC filter, its low-inductance SOT23 layout and fast clamping enable compliant system-level CE/EMC testing when placed per Nexperia's PCB layout guidelines.
