Product details
Overview
PESD48VV2BTR from Nexperia is a dual-channel unidirectional ESD protection diode array in SOT23 package, designed to safeguard two 48 V signal lines against IEC 61000-4-2 (±30 kV contact) and ISO 10605 transients. It features 48 V reverse stand-off voltage, 67 V clamping at 3.5 A, 7.1 pF typical capacitance, <1 nA leakage, and matched capacitance tolerance of ±0.5 % - enabling robust transient suppression in high-voltage USB-C EPR interfaces.
For engineers reviewing the PESD48VV2BTR datasheet, PESD48VV2BTR pinout, PESD48VV2BTR application, or PESD48VV2BTR equivalent, key selection criteria include 48 V line compatibility, low clamping voltage under 8/20 µs surge, sub-8 pF capacitance for high-speed signal integrity, dual-line symmetry, and SOT23 footprint constraints in space-constrained USB-C connector layouts.
Technical Context
This device implements two independent silicon avalanche diodes with a shared cathode (Pin 3), forming a common-cathode dual-diode configuration optimized for bidirectional transient suppression on two separate 48 V lines. Each channel provides precise 48 V standoff and fast response to ESD events without forward conduction during normal operation.
Clamping occurs at 67 V (typ.) under 3.5 A 8/20 µs pulse, with dynamic resistance of 0.55 Ω measured via TLP at 100 ns, ensuring minimal voltage overshoot. Capacitance matching (∆Cd/Cd = 0.5 %) supports differential signaling integrity in CC/SBU pairs of USB Type-C EPR implementations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 48 V - Ensures no conduction during normal 48 V line operation; defines maximum continuous working voltage before breakdown. |
| Clamping Voltage (VCL) | 67 V at IPPM = 3.5 A - Limits transient voltage seen by downstream ICs to safe levels during 8/20 µs surges. |
| Diode Capacitance (Cd) | 7.1 pF at 1 MHz, 0 V - Preserves signal integrity on high-speed USB-C CC/SBU lines without excessive loading. |
| Capacitance Matching (∆Cd/Cd) | 0.5 % - Enables balanced transient response across dual channels, critical for differential pair protection. |
| ESD Withstand Rating | ±30 kV per IEC 61000-4-2 (contact) - Meets industrial and consumer-grade ESD immunity requirements without external circuitry. |
| Leakage Current (IRM) | <1 nA at VRWM = 48 V - Prevents DC power loss and avoids interference with high-impedance sensing or bias networks. |
| Peak Pulse Current (IPPM) | 3.5 A (8/20 µs) - Supports robust surge handling while maintaining low clamping and thermal stability in SOT23 package. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; optimized for automated placement and reflow soldering near high-density USB-C connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode, Diode 1) | Connects to first protected line (e.g., USB-C CC1); anode tied internally to Pin 3 for unidirectional clamping to ground. |
| 2 | K2 (Cathode, Diode 2) | Connects to second protected line (e.g., USB-C SBU1); enables independent transient suppression on dual 48 V paths. |
| 3 | K (Common Cathode) | Shared cathode node - must be connected directly to system ground plane with minimal inductance for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel 48 V standoff | Enables simultaneous protection of two independent 48 V lines (e.g., CC and SBU) without cross-talk or shared impedance issues. |
| Sub-8 pF capacitance | Maintains signal rise/fall times & impedance continuity on USB-C sideband use (SBU) and configuration channel (CC) lines. |
| 0.5 % capacitance matching | Ensures symmetrical transient response across both channels - essential for differential signaling integrity in EPR applications. |
| 0.55 Ω dynamic resistance | Minimizes voltage overshoot during fast transients (TLP 100 ns), improving protection margin for sensitive 48 V interface ICs. |
| Low leakage & thermal stability | <1 nA IR at 48 V and 150 °C junction rating support long-term reliability in automotive-adjacent and industrial 48 V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel 48 V ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | 42 V VRWM, higher 85 V VCL at 3.5 A, 12 pF capacitance | Not suitable for strict 48 V line operation; higher clamping risks downstream IC stress | Select only if system operates ≤42 V and capacitance tolerance >12 pF is acceptable |
| Vishay VEML6035X01 | Single-channel, 48 V VRWM, but lacks dual-line integration and capacitance matching | Requires two devices + layout balancing for dual-line use, increasing board area and skew risk | Use only when discrete layout control justifies added complexity and cost over integrated dual solution |
Compared with NUP4202MR6T1G and VEML6035X01, PESD48VV2BTR uniquely delivers true 48 V standoff, matched 7.1 pF capacitance, and monolithic dual-channel integration - reducing component count, PCB area, and inter-channel timing skew in USB-C EPR and industrial 48 V data interfaces.

FAQ
Is PESD48VV2BTR suitable for bidirectional signal lines like USB-C CC?
Yes - though internally unidirectional (cathode-referenced), its common-cathode SOT23 configuration allows bidirectional transient suppression when Pin 3 is grounded. The 48 V VRWM ensures no conduction during normal CC line voltage swings (±1.2 V), while clamping activates only during positive transients on either line relative to ground.
What is the recommended PCB layout for optimal ESD performance?
Place PESD48VV2BTR within 3 mm of the USB-C connector, route protected lines directly to Pins 1 and 2 with minimum trace length, connect Pin 3 to a solid ground plane using ≥2 vias, and avoid routing unprotected traces parallel to protected ones. Follow Nexperia's sot023_fr footprint for reflow reliability.
Does PESD48VV2BTR meet automotive qualification standards?
No - this device is not AEC-Q200 qualified. Its 150 °C junction rating and 48 V capability support automotive-adjacent applications (e.g., mild hybrid ECUs), but it lacks formal automotive qualification, stress testing, or PPAP documentation required for safety-critical vehicle systems.
How does capacitance matching impact USB-C SBU pair performance?
The 0.5 % ∆Cd/Cd ensures near-identical transient response on both SBU1 and SBU2 lines, preventing differential skew during ESD events. This preserves eye diagram integrity for sideband-use protocols (e.g., DisplayPort Alt Mode) and avoids false detection in high-speed link training sequences.
