Product details
Overview
PESD15VL2BT from Nexperia is a low-capacitance, double bidirectional ESD protection diode in SOT23 package, designed to safeguard two signal lines against ±30 kV IEC 61000-4-2 ESD and 5 A IEC 61000-4-5 surge transients. 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 data line protection in portable electronics.
For engineers reviewing the PESD15VL2BT datasheet, PESD15VL2BT pinout, PESD15VL2BT application, or PESD15VL2BT equivalent, key selection criteria include bidirectional clamping symmetry, sub-20 V breakdown (17.1–20.3 V), ultra-low leakage for battery-sensitive designs, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a dual-cathode, symmetric bidirectional TVS structure-pins 1 and 2 serve as independent cathodes, while pin 3 is the shared cathode node-enabling simultaneous protection of two differential or independent signal paths without polarity constraints. Its clamping behavior is characterized by 44 V max at 5 A (8/20 µs) and 25 V at 1 A.
The diode operates within a 15 V reverse standoff range (VRWM), exhibits 225 Ω differential resistance at 1 mA, and maintains stable performance across −65 °C to +150 °C ambient and junction temperatures. Capacitance remains flat (<16 pF) up to 10 V reverse bias, critical for USB 2.0, HDMI, and SIM card interface integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous operating voltage before conduction begins; ensures no interference with 12 V or 15 V logic/signal rails. |
| Breakdown Voltage | 17.1–20.3 V @ 5 mA - Defined turn-on threshold for transient suppression; guarantees early clamping onset during fast ESD events. |
| Clamping Voltage | 44 V @ 5 A (8/20 µs) - Peak voltage seen by protected circuit under worst-case surge; limits stress on downstream ICs. |
| Diode Capacitance | 16 pF @ 1 MHz, 0 V - Enables use on high-speed interfaces (e.g., USB 2.0, audio codecs) without signal integrity degradation. |
| Leakage Current | 1 nA @ 15 V - Minimizes standby power loss in battery-powered devices such as handsets and wearables. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - Meets industrial and consumer immunity requirements without external shielding. |
| Surge Rating | 5 A (8/20 µs, IEC 61000-4-5) - Withstands lightning-induced surges on communication ports and peripheral connectors. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for reflow soldering per JEDEC MS-012 (TO-236AB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | First cathode terminal - connects to Line 1; forms one half of the bidirectional clamp path to common cathode (pin 3). |
| 2 | K2 | Second cathode terminal - connects to Line 2; forms second independent clamp path to common cathode (pin 3). |
| 3 | CC | Common cathode - ties both K1 and K2 to system ground or reference plane; enables dual-line protection with single return path. |
Key Features
| Feature | Design Value |
|---|---|
| Double bidirectional protection | Simultaneously guards two independent signal lines (e.g., D+ and D−, or SIM CLK and SIM I/O) with matched clamping characteristics. |
| Ultra-low 16 pF capacitance | Preserves signal rise/fall times on >480 Mbps interfaces without added jitter or attenuation. |
| 1 nA reverse leakage | Reduces quiescent current drain in always-on mobile peripherals, extending battery life in sleep-mode operation. |
| 200 W peak pulse power | Handles repetitive ESD events without parameter shift or thermal runaway under standard board-level test conditions. |
| IEC 61000-4-2/4-5 certified | Validated to full compliance for end-equipment CE/FCC/UL certification without additional external filtering. |
Applications
| USB 2.0 Data Lines | SIM Card Interface |
|---|---|
|
Use Scenario: Protection of D+ and D− pins on smartphone USB ports exposed to frequent hot-plug and electrostatic handling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point to shunt ESD energy before reaching USB PHY. Use Value: 16 pF capacitance avoids signal distortion at 480 Mbps; 44 V clamping prevents damage to 3.3 V tolerant PHY inputs. |
Use Scenario: Guarding SIM clock, data, and reset lines in mobile handsets where space and leakage are critical constraints. IC Role / Device Role / Timing Role: Dual-line ESD clamp sharing ground return, minimizing PCB real estate versus discrete diodes. Use Value: 1 nA leakage preserves battery runtime during SIM card presence detection; ±30 kV rating exceeds EN 61000-4-2 requirements. |
| Audio Codec Interfaces | Industrial Sensor Signal Lines |
|
Use Scenario: Protecting analog audio input/output paths (e.g., headset jack mic/bias lines) in tablets and smart speakers. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp preventing pop/noise injection and amplifier latch-up during user handling. Use Value: Flat 16 pF vs. voltage ensures consistent frequency response; 225 Ω dynamic resistance minimizes signal attenuation. |
Use Scenario: Shielding RS-485 or analog sensor outputs (e.g., temperature, pressure) in factory automation equipment subject to cable-borne surges. IC Role / Device Role / Timing Role: Primary front-end surge limiter on field-side signal traces, coordinated with PCB layout best practices. Use Value: 5 A IEC 61000-4-5 rating handles induced transients from nearby motor switching; −65 °C to +150 °C rating supports extended industrial temperature operation. |
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 NUP4201MR6T1G | Higher capacitance (30 pF), lower ESD rating (±15 kV), same SOT23-3 package and dual-line topology. | Less suitable for >100 Mbps interfaces; acceptable for lower-speed UART or GPIO protection. | Select when cost sensitivity outweighs speed requirements and 30 kV ESD immunity is not mandated. |
| Vishay ESDBLE5.0D1W | Lower clamping (27 V @ 5 A), higher leakage (5 nA), identical 15 V VRWM and 16 pF capacitance. | Better for low-voltage 3.3 V systems needing tighter clamping; trade-off is increased standby current. | Prefer for battery-constrained IoT sensors where 27 V clamping improves margin over 3.3 V rail, accepting 5× leakage. |
Compared with NUP4201MR6T1G and ESDBLE5.0D1W, PESD15VL2BT uniquely balances 30 kV ESD immunity, 16 pF capacitance, and 1 nA leakage-making it optimal for high-speed, low-power portable interfaces where all three parameters are simultaneously constrained.

FAQ
What is the maximum operating temperature for PESD15VL2BT?
The PESD15VL2BT has a maximum junction temperature of 150 °C and an ambient operating range of −65 °C to +150 °C, validated per IEC 60134 limiting values. Thermal derating applies above 25 °C ambient, with peak pulse power dropping to ~70% at 100 °C junction temperature per Figure 4 in the datasheet.
Can PESD15VL2BT protect AC-coupled or bipolar signal lines?
Yes-the symmetric bidirectional structure (K1–CC and K2–CC) allows protection of signals swinging above and below ground, including AC-coupled USB D+/D−, audio differential pairs, and SIM card clock/data lines. No DC bias is required; clamping activates equally for positive and negative transients.
How does the SOT23 footprint impact PCB layout for ESD performance?
Optimal ESD performance requires placing the PESD15VL2BT within 3 mm of the protected connector, routing protected traces directly to pins 1 and 2 with minimal stub length, and connecting pin 3 to a low-inductance ground plane via multiple vias-per Nexperia's layout guidelines in Section 10 of the datasheet.
Is PESD15VL2BT qualified for automotive applications?
No-this variant is non-automotive qualified, as confirmed in the revision history (Section 13). For automotive use, Nexperia offers the PESD15VL2BT-Q series, which undergoes AEC-Q101 qualification and includes extended temperature testing, enhanced robustness validation, and PPAP documentation support.
