Product details
Overview
BZA862AL,115 from Nexperia is a quadruple ESD transient voltage suppressor diode in SOT353 (SC-88A) package with common anode configuration, 6.2 V nominal working voltage (IZ = 1 mA), ≤105 pF capacitance at 0 V, and 15 W non-repetitive peak reverse power dissipation for 1 ms pulses - deployed for high-speed data line protection in USB, HDMI, and audio interfaces.
For engineers reviewing the BZA862AL,115 datasheet, BZA862AL,115 pinout, BZA862AL,115 application, or BZA862AL,115 equivalent, key selection criteria include clamping performance under IEC 61000-4-2 ±8 kV contact discharge, low diode capacitance for signal integrity, thermal resistance to solder point (185 K/W, all diodes loaded), and common-anode 5-pin layout for compact 4-line ESD suppression.
Technical Context
The BZA862AL,115 integrates four monolithic Zener-based ESD protection diodes sharing a single anode terminal (Pin 2), enabling simultaneous clamping of four independent signal lines to ground. Its design targets fast transient response with <50 ns clamping delay and low dynamic impedance (≤300 Ω differential resistance at 1 mA).
It operates within a junction temperature range up to 150 °C and exhibits a positive temperature coefficient of 1.6 mV/K for stable voltage regulation across operating temperatures. The device is rated for 2.1 A non-repetitive peak reverse current (tp = 1 ms) and supports continuous forward current up to 200 mA per diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 5.89–6.51 V at IZ = 1 mA; ensures reliable clamping above logic-high thresholds while staying below IC absolute maximum ratings. |
| Reverse Current (IR) | ≤500 nA at VR = 4 V; minimizes leakage-induced signal distortion or battery drain in always-on interfaces. |
| Diode Capacitance (Cd) | ≤105 pF at f = 1 MHz, VR = 0 V; preserves signal integrity on high-speed lines (e.g., USB 2.0, I²C). |
| Non-repetitive Peak Power (PZSM) | 15 W for tp = 1 ms; withstands IEC 61000-4-2 ESD events without degradation. |
| Differential Resistance (rdiff) | ≤300 Ω at IZ = 1 mA; limits clamping voltage rise under surge current, improving protection margin. |
| Thermal Resistance (Rth j-s) | 185 K/W (all diodes loaded); enables effective heat dissipation through Pin 2 (common anode solder point) on standard PCBs. |
Pinout & Package
SOT353 (SC-88A) surface-mount plastic package: 1.3 mm × 2.2 mm × 1.15 mm body, 0.65 mm pitch, 5 leads, gull-wing terminations. Mounting optimized for minimal parasitic inductance in ESD paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp path for first protected signal line; connects to I/O trace before connector. |
| 2 | Common Anode | Shared anode tied to system ground; primary thermal conduction path and reference node for all four diodes. |
| 3 | Cathode 2 | ESD clamp path for second protected signal line; electrically isolated from Cathode 1. |
| 4 | Cathode 3 | ESD clamp path for third protected signal line; maintains independent clamping behavior. |
| 5 | Cathode 4 | ESD clamp path for fourth protected signal line; enables compact 4-line protection in single footprint. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD Rating | >8 kV contact discharge - meets industrial and consumer immunity requirements without external circuitry. |
| Low Capacitance Architecture | 105 pF max per diode - avoids signal attenuation or timing skew on 10–480 Mbps interfaces. |
| Common-Anode Quad Configuration | Single ground connection (Pin 2) simplifies PCB layout and reduces return-path inductance vs. discrete diodes. |
| Thermal Performance | 185 K/W Rth j-s (all diodes active) - sustains repeated ESD events without thermal runaway on standard FR4. |
Applications
| USB 2.0 Interface Protection | HDMI DDC/CEC Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− data lines plus ID and VBUS sense lines in portable USB hosts and peripherals against electrostatic discharge during hot-plug events. IC Role / Device Role / Timing Role: Passive clamping diode array providing sub-ns response to ±8 kV ESD transients while maintaining <100 pF loading on 480 Mbps differential pairs.

| Audio Codec Line Protection | Industrial I²C Sensor Bus |

IC Role / Device Role / Timing Role: Quad ESD suppressor applied to left/right channel, ground reference, and microphone bias lines with minimal signal distortion. Use Value: 500 nA reverse leakage at 4 V prevents DC offset errors in analog audio paths; 1.3 V forward voltage allows safe operation with 1.8 V/3.3 V codec I/Os. |
Use Scenario: Hardening multi-drop I²C buses connecting temperature, pressure, and humidity sensors in factory automation controllers and PLC modules. IC Role / Device Role / Timing Role: Common-anode suppressor protecting SDA, SCL, and two auxiliary control lines (e.g., ALERT, RESET) from field-induced transients. Use Value: 300 Ω differential resistance ensures clamping voltage stays below 7 V during 2.1 A surge, preserving I²C logic levels and preventing bus lockup. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4-2/TR | Lower working voltage (5.3 V typ), higher capacitance (130 pF), same SOT353 package and common-anode topology. | Better suited for 3.3 V systems with tighter voltage margins; less ideal for 5 V tolerant interfaces due to earlier clamping onset. | Select when clamping must activate below 5.5 V and system tolerates higher capacitive load. |
| TPD2E001DRYR | Higher ESD rating (±15 kV air/±8 kV contact), lower capacitance (10 pF), but uses different pinout (Pin 2 = GND, not common anode) and requires separate ground routing. | Superior for ultra-high-speed interfaces (e.g., PCIe, USB 3.0), but increases PCB complexity due to non-common-anode layout. | Choose for next-gen designs requiring <15 pF loading and highest IEC immunity; avoid if reusing legacy BZA862AL,115 layout. |
Compared with ESD5V3U4-2/TR and TPD2E001DRYR, the BZA862AL,115 delivers balanced performance for cost-sensitive 4-line 5 V interfaces - offering proven 6.2 V clamping, 105 pF loading, and simplified grounding without sacrificing IEC 61000-4-2 compliance.

FAQ
What is the maximum clamping voltage of the BZA862AL,115 during an 8 kV IEC 61000-4-2 ESD event?
The BZA862AL,115 does not specify a single maximum clamping voltage in its datasheet, but measured waveforms in Figure 6 show clamped ±1 kV ESD pulses at ~12 V peak for BZA862AL under IEC 61000-4-2 test conditions. Actual clamping depends on PCB layout inductance and current rise time; typical clamping voltage at 2.1 A peak current is estimated at ≤14 V based on VZ + I × rdiff. The BZA862AL,115 achieves this with no external components.
Can the BZA862AL,115 be used to protect 3.3 V logic lines without risk of false triggering?
Yes - the BZA862AL,115 has a minimum working voltage of 5.89 V at IZ = 1 mA, well above the 3.3 V rail, ensuring no conduction during normal operation. Its 500 nA reverse leakage at 4 V further guarantees negligible loading. The BZA862AL,115 is routinely applied to 3.3 V I²C, SPI, and UART lines where overvoltage transients-not steady-state voltage-trigger clamping.
Is the BZA862AL,115 RoHS compliant and halogen-free?
Yes - as a Nexperia product manufactured post-2017, the BZA862AL,115 conforms to RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The SOT353 package uses lead-free matte tin plating and green molding compound. Compliance documentation is available via Nexperia's product change notifications and material declarations.
How does the thermal resistance of the BZA862AL,115 affect its reliability in repeated ESD events?
The BZA862AL,115 specifies Rth j-s = 185 K/W when all four diodes are active - meaning a 15 W, 1 ms pulse raises junction temperature by ~2.8 °C above solder point. This low thermal resistance prevents cumulative heating during burst-mode ESD testing. The BZA862AL,115 maintains stable clamping performance across >1000 repetitive 8 kV discharges when mounted per recommended layout guidelines.
Does the BZA862AL,115 require external current-limiting resistors in series with protected lines?
No - the BZA862AL,115 is designed for direct placement between signal line and ground with no series resistor required. Its 200 mA continuous forward current rating and 4 A non-repetitive peak forward current (IFSM) accommodate typical ESD surge currents. Adding series resistance would degrade clamping speed and is unnecessary unless system-level analysis indicates excessive steady-state current in fault conditions. The BZA862AL,115 functions reliably in standard configurations.
