Product details
Overview
BZA868A,115 from Nexperia is a quadruple ESD transient voltage suppressor diode in SOT353 (SC-88A) package with common anode configuration, 6.8 V working voltage (VZ), ≤180 pF capacitance at 0 V, ≤200 Ω differential resistance, and >8 kV ESD rating per IEC 1000-4-2 - used for high-speed data line protection in USB, HDMI, and audio interfaces.
For engineers reviewing the BZA868A,115 datasheet, BZA868A,115 pinout, BZA868A,115 application, or BZA868A,115 equivalent, key selection criteria include clamping performance under ±1 kV IEC 61000-4-2 ESD pulses, low capacitance for signal integrity preservation, thermal derating above 25 °C, and common-anode layout compatibility with multi-line I/O protection.
Technical Context
The BZA868A,115 integrates four monolithic Zener-type ESD protection diodes sharing a single anode terminal, enabling compact 4-line suppression in one SOT353 footprint. Its clamping behavior is defined by VZ = 6.8 V (typ.), rdiff = 200 Ω (max), and IZSM = 2.6 A (1 ms pulse), with junction temperature limited to 150 °C.
Designed for low-capacitance interface protection, it delivers Cd = 180 pF (max) at 0 V reverse bias and exhibits a positive temperature coefficient of +3 mV/K, ensuring stable clamping across operating temperatures. Thermal resistance Rth j-a is 370 K/W with all diodes loaded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 6.8 V (typ.) at IZ = 1 mA - defines minimum clamping threshold for ESD transients on protected lines. |
| Reverse Leakage (IR) | 200 nA max at VR = 4.3 V - ensures negligible standby current in battery-powered or low-power I/O circuits. |
| Diode Capacitance (Cd) | 180 pF max at f = 1 MHz, VR = 0 - preserves signal integrity on high-speed digital lines (e.g., USB 2.0, I²C). |
| Differential Resistance (rdiff) | 200 Ω max at IZ = 1 mA - determines dynamic clamping voltage rise (ΔV = rdiff × ΔI) during fast ESD events. |
| ESD Rating | >8 kV contact discharge per IEC 61000-4-2 - meets industrial and consumer equipment immunity requirements. |
| Peak Pulse Power (PZSM) | 24 W (1 ms square pulse) - supports robust transient energy absorption without thermal runaway. |
| Junction Temperature (Tj) | 150 °C max - sets upper limit for continuous operation and derating curve (Fig.5). |
Pinout & Package
SOT353 (SC-88A) surface-mount plastic package: 5-lead, 1.3 mm × 1.8 mm × 1.1 mm body, 0.65 mm pitch, gull-wing leads. Thermal resistance Rth j-a = 370 K/W when all diodes are loaded.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected line 1 connection; reverse-biased during ESD event to clamp voltage to VZ. |
| 2 | Common Anode | Shared anode node tied to system ground or reference plane - enables compact 4-line protection routing. |
| 3 | Cathode 2 | Protected line 2 connection; electrically isolated but thermally coupled to other cathodes in monolithic die. |
| 4 | Cathode 3 | Protected line 3 connection; identical electrical characteristics to pins 1 and 3 per datasheet specs. |
| 5 | Cathode 4 | Protected line 4 connection; allows simultaneous protection of quad-data buses (e.g., parallel I/O, address lines). |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD compliance | >8 kV contact discharge - eliminates need for external ESD test failure rework in end-equipment certification. |
| Low diode capacitance | 180 pF max - prevents signal distortion and timing skew on 480 Mbps USB 2.0 or 25 MHz I²C buses. |
| Common anode architecture | Single ground return path for 4 channels - reduces PCB trace count and minimizes loop area vs. discrete diode solutions. |
| Thermally optimized monolithic die | Rth j-a = 370 K/W with full loading - enables sustained operation up to 85 °C ambient without derating below 200 mW Ptot. |
| Stable temperature coefficient | +3 mV/K - ensures predictable VZ drift over -40 °C to +125 °C, critical for automotive infotainment I/O protection. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
|
Use Scenario: Protection of D+ and D− differential pair plus ID and VBUS detect lines in portable USB hosts/peripherals. IC Role / Device Role / Timing Role: Quad-channel ESD clamp placed within 3 mm of USB connector, with common anode grounded to chassis.

Use Scenario: ESD protection of HDMI Display Data Channel (DDC) clock/data and Consumer Electronics Control (CEC) lines. IC Role / Device Role / Timing Role: Single-device solution for three low-speed bidirectional lines, minimizing board space vs. three discrete suppressors. Use Value: 180 pF capacitance avoids violating HDMI 1.4a's 100 pF max per line requirement when combined with PCB parasitics. |
| Industrial I/O Terminals | Audio Codec Interface |
|
Use Scenario: Transient suppression on RS-485/RS-232 control lines and sensor input channels in PLC modules. IC Role / Device Role / Timing Role: Common-anode configuration simplifies grounding to isolated logic ground while referencing analog ground via TVS array. Use Value: 24 W peak power rating handles multiple 1 kV ESD strikes without degradation, supporting 10-year field reliability. |
Use Scenario: Protection of stereo I²S data, word clock, and left-right clock lines between codec and SoC in smart speakers. IC Role / Device Role / Timing Role: Low-leakage (200 nA) operation prevents DC offset shift in high-impedance audio bias networks. Use Value: 6.8 V working voltage aligns with 3.3 V I/O rail, ensuring clamping occurs before downstream ESD-sensitive amplifier inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | Lower VZ = 6.1 V (typ.), higher Cd = 220 pF, same SOT353 package and common-anode pinout. | Better for 3.3 V systems requiring tighter clamping margin; less suitable for high-speed lines due to +40 pF capacitance penalty. | Select ESDA6V1SC6 when clamping voltage headroom is critical and signal bandwidth ≤10 MHz. |
| TPD4E001DQAR | Higher VZ = 7.5 V (min), lower Cd = 12 pF, same 5-pin SOT353 footprint but different pin assignment (anode on pin 3). | Superior for >100 MHz interfaces (e.g., MIPI D-PHY); requires PCB layout revision due to non-identical pinout. | Choose TPD4E001DQAR only if redesigning for ultra-low capacitance and accepting pinout change. |
Compared with ESDA6V1SC6 and TPD4E001DQAR, the BZA868A,115 offers the optimal balance of clamping voltage (6.8 V), capacitance (180 pF), and drop-in compatibility - making it preferred for cost-sensitive, high-volume USB and industrial I/O designs where layout reuse is mandatory.

FAQ
What is the maximum clamping voltage of the BZA868A,115 during an 8 kV IEC 61000-4-2 ESD event?
The BZA868A,115 does not specify a single "maximum clamping voltage" for 8 kV ESD events in its datasheet. Instead, clamping voltage depends on peak current (IZSM = 2.6 A) and differential resistance (rdiff ≤ 200 Ω), yielding a typical clamping level of ~12 V at 2.6 A. Actual measured clamping must be validated per Fig.6 test setup using the IEC 1000-4-2 network.
Is the BZA868A,115 RoHS compliant and halogen-free?
Yes, the BZA868A,115 is RoHS compliant and halogen-free per Nexperia's product compliance documentation. It meets EU Directive 2011/65/EU and IEC 61249-2-21:2011 standards, with lead-free terminations and no brominated flame retardants in the molding compound.
Can the BZA868A,115 be used to protect 5 V logic lines?
Yes, the BZA868A,115 is suitable for protecting 5 V logic lines. Its 6.8 V working voltage provides sufficient margin above the 5 V rail while ensuring reliable clamping before damage occurs to downstream 5 V-tolerant ICs, provided layout follows Nexperia's guidelines for minimal trace inductance.
Does the BZA868A,115 require external series resistors for optimal ESD protection?
No, the BZA868A,115 does not require external series resistors for basic ESD protection. However, adding small resistors (e.g., 10–33 Ω) between the protected line and the BZA868A,115 cathode can reduce di/dt-induced overshoot and improve clamping consistency - especially in high-speed applications like USB 2.0.
What is the storage temperature range for the BZA868A,115?
The BZA868A,115 has a specified storage temperature range of −65 °C to +150 °C, as defined in the Limiting Values table. This allows safe long-term storage in uncontrolled environments and compatibility with standard reflow soldering profiles including peak temperatures up to 260 °C for 10 seconds.
