Product details
Overview
ESD862DBZR from Texas Instruments is a 2-channel, bidirectional ESD protection diode in SOT-23 (DBZ) package, rated for ±18kV IEC 61000-4-2 contact/air discharge, 3.1A IEC 61000-4-5 (8/20µs) surge current, and 2.6pF typical line capacitance - designed for USB-PD VBUS and industrial I/O line protection.
For engineers reviewing the ESD862DBZR datasheet, ESD862DBZR pinout, ESD862DBZR application, or ESD862DBZR equivalent, this page delivers verified electrical specs, real-world clamping behavior, thermal resistance data, and precise SOT-23 pin mapping to support robust transient protection design in CAN-FD, factory automation, and USB power delivery systems.
Technical Context
The ESD862DBZR implements a dual-channel, symmetric bidirectional TVS structure with snapback-triggered clamping, enabling low-voltage overshoot during ±18kV ESD events. Its 0.49Ω dynamic resistance ensures minimal voltage rise under 3.1A surge current.
Operating at ±36V working voltage with 50nA max leakage at ±36V, it maintains signal integrity on high-speed industrial interfaces while meeting IEC 61000-4-5 Level 3 surge immunity. The SOT-23 package supports AOI-compatible assembly and provides 313.5°C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±36V - defines maximum continuous DC or peak AC signal swing before leakage rises significantly. |
| ESD Rating (IEC 61000-4-2) | ±18kV contact / ±18kV air - validated system-level ESD immunity for industrial and USB-PD ports. |
| Surge Current (IEC 61000-4-5) | 3.1A (8/20µs) - withstands repetitive lightning-induced surges on protected lines without degradation. |
| Clamping Voltage | 61V at 3.1A - limits downstream IC stress to safe levels during worst-case transient events. |
| Line Capacitance | 2.6pF typical - preserves signal rise/fall times on USB-PD and CAN-FD buses up to 5 Mbps. |
| Leakage Current | 50nA max at ±36V - avoids loading of high-impedance sensor or reference circuits. |
| Dynamic Resistance | 0.49Ω - enables fast, low-overshoot clamping response critical for protecting sensitive transceivers. |
Pinout & Package
SOT-23 (DBZ) package: 3-pin, surface-mount, leaded plastic case with 1.12mm max height, optimized for automatic optical inspection (AOI) and reflow compatibility (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Channel A | Bidirectionally protected signal line - connects to USB-PD VBUS or CANH/CANL. |
| 2 | I/O Channel B | Second protected signal line - used for IO pair protection or redundant path. |
| 3 | GND | Low-inductance return path for ESD current - must be tied directly to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of both positive and negative transients on same line without polarity constraints. |
| 2.6pF typical capacitance | Minimizes signal distortion on USB-PD CC lines and CAN-FD differential pairs operating below 5 Mbps. |
| ±18kV IEC 61000-4-2 rating | Meets industrial-grade ESD immunity requirements for factory automation and communication equipment interfaces. |
| 313.5°C/W RθJA | Supports operation up to +150°C ambient in enclosed enclosures without derating under typical PCB layout conditions. |
| Leaded SOT-23 package | Enables reliable AOI inspection and eliminates solder joint voiding risks common in no-lead packages. |
Applications
| USB Power Delivery (VBUS Protection) | Industrial CAN-FD Bus Protection |
|---|---|
Use Scenario: Protecting USB-PD VBUS lines against hot-plug transients and ESD during cable insertion. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between VBUS and chassis ground to shunt surge energy away from controller ICs. Use Value: 61V clamping at 3.1A prevents overvoltage damage to USB-PD source/sink controllers during 8/20µs surges. |
Use Scenario: Safeguarding CANH/CANL differential pair in automotive or factory automation gateways exposed to ESD and load dump. IC Role / Device Role / Timing Role: Dual-channel TVS connected across CANH–GND and CANL–GND to clamp common-mode transients. Use Value: 2.6pF capacitance avoids signal edge degradation on 5 Mbps CAN-FD links while sustaining ±18kV contact ESD. |
| Factory Automation I/O Protection | Communication Equipment Data Lines |
Use Scenario: Shielding digital input/output lines on PLC modules from ESD events during field wiring or maintenance. IC Role / Device Role / Timing Role: Two independent I/O protection paths sharing one GND terminal - ideal for isolated sensor or actuator interfaces. Use Value: 50nA leakage ensures compatibility with high-impedance analog input conditioning stages upstream of ADCs. |
Use Scenario: Securing RS-485 or Ethernet PHY data lanes in telecom infrastructure against electrostatic discharge during board handling. IC Role / Device Role / Timing Role: Low-capacitance ESD suppressor placed at connector interface to divert transients before reaching transceiver IC. Use Value: 0.49Ω dynamic resistance achieves sub-65V clamping even under 3.1A surge, preserving PHY latch-up immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD852DBZR | Higher ESD rating (±25kV), higher surge current (4.3A), 2.8pF capacitance, same SOT-23 package. | Better suited for USB-PD VBUS where higher surge margin is required; slightly higher capacitance may affect >10 Mbps signals. | Select ESD852DBZR when system-level testing requires ≥±25kV contact ESD immunity or 4.3A surge headroom. |
| TPD2E001DRSR | 2-channel, ±12kV IEC 61000-4-2, 1.5A IEC 61000-4-5, 1.5pF capacitance, DFN1006-3 package. | Lower ESD/surge ratings but lower capacitance - optimized for high-speed data lines like USB 2.0 or HDMI. | Choose TPD2E001DRSR only for space-constrained designs needing <2pF capacitance and where ±12kV ESD suffices. |
Compared with ESD852DBZR, ESD862DBZR trades 7kV ESD margin and 1.2A surge capacity for reduced capacitance (2.6pF vs. 2.8pF), making it optimal for cost-sensitive industrial I/O where ±18kV meets compliance. TPD2E001DRSR offers smaller footprint and lower capacitance but lacks the robustness needed for USB-PD VBUS or CAN-FD bus protection.

FAQ
What is the maximum continuous operating voltage for ESD862DBZR?
The ESD862DBZR has a reverse stand-off voltage (VRWM) of ±36V, meaning it can continuously block up to ±36V DC or peak AC signals without significant leakage. This rating ensures compatibility with USB-PD VBUS (up to 20V nominal, 48V max) and industrial 24V control lines while maintaining 50nA max leakage at full rating.
Does ESD862DBZR support bidirectional signal protection?
Yes, ESD862DBZR is a fully bidirectional ESD protection diode - each I/O pin (pins 1 and 2) conducts equally in both polarities relative to GND (pin 3). This allows it to protect AC-coupled or differential signals like CANH/CANL without polarity concerns, and eliminates need for external series resistors or directional biasing.
What is the clamping voltage of ESD862DBZR under IEC 61000-4-5 surge conditions?
Under IEC 61000-4-5 8/20µs surge waveform at 3.1A peak current, the ESD862DBZR clamps to 61V (typical) from I/O to GND. This value is measured per device specification and ensures protected downstream ICs see less than 65V transient stress - critical for safeguarding 3.3V/5V logic and transceivers in industrial environments.
Can ESD862DBZR be used for USB-C CC line protection?
Yes, ESD862DBZR is suitable for USB-C configuration channel (CC) line protection due to its 2.6pF typical capacitance, ±36V working voltage, and ±18kV IEC 61000-4-2 rating. Its low capacitance avoids skew or attenuation on the 300kHz CC signaling, and its bidirectional behavior matches the dual-role nature of CC pins in source/sink negotiation.
What is the thermal resistance of ESD862DBZR in standard PCB layout?
The ESD862DBZR in SOT-23 (DBZ) package has a junction-to-ambient thermal resistance (RθJA) of 313.5°C/W under standard JEDEC test conditions (1sq-in 2oz copper). In typical 4-layer PCB layouts with 2cm² ground pour under the device, actual RθJA improves to ~120–150°C/W, supporting reliable operation up to +125°C ambient without derating.
