Product details
Overview
BZA868AL,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 (IZ = 1 mA), ≤90 pF capacitance at 0 V, and 14 W non-repetitive peak reverse power dissipation - designed for high-speed data line protection in USB, HDMI, and audio interfaces.
For engineers reviewing the BZA868AL,115 datasheet, BZA868AL,115 pinout, BZA868AL,115 application, or BZA868AL,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 (Rth j-a = 410 K/W), and common-anode 5-pin layout for compact 4-line ESD protection.
Technical Context
The BZA868AL,115 integrates four monolithic Zener-type ESD protection diodes sharing a single anode terminal (Pin 2), enabling simultaneous suppression of transients on four independent signal lines. Its design targets fast clamping response to sub-nanosecond ESD pulses per IEC 61000-4-2, with specified VZSM derived from measured IZSM and PZSM curves.
Electrical behavior is defined by Zener breakdown characteristics: 6.8 V nominal working voltage (6.46–7.14 V min/max), 200 Ω max differential resistance, and +2.2 mV/K temperature coefficient - ensuring stable clamping across industrial temperature range (−65 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 6.8 V at IZ = 1 mA - sets minimum clamping threshold for reliable protection of 5 V logic and analog interfaces |
| Reverse Current (IR) | ≤100 nA at VR = 4.3 V - ensures negligible leakage in standby, critical for battery-powered sensor I/O |
| Diode Capacitance (Cd) | ≤90 pF at f = 1 MHz, VR = 0 - preserves signal integrity on high-speed lines up to ~100 MHz |
| Peak Reverse Power (PZSM) | 14 W at tp = 1 ms - supports robust handling of IEC 61000-4-2 ESD events without degradation |
| Thermal Resistance (Rth j-a) | 410 K/W - defines maximum allowable ambient temperature rise under full-load dissipation |
| ESD Rating | >8 kV contact discharge per IEC 61000-4-2 - certified immunity level for end-equipment compliance testing |
Pinout & Package
SOT353 (SC-88A) surface-mount package: 5-lead plastic package with 1.3 mm × 1.8 mm body, 0.65 mm pitch, and 1.1 mm height - optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD protection path for first signal line; connects to protected I/O trace |
| 2 | Common Anode | Shared ground return for all four diodes; must connect directly to low-inductance system ground |
| 3 | Cathode 2 | ESD protection path for second signal line; electrically isolated from Cathode 1 |
| 4 | Cathode 3 | ESD protection path for third signal line; independent clamping node |
| 5 | Cathode 4 | ESD protection path for fourth signal line; enables 4-bit parallel bus protection in one footprint |
Key Features
| Feature | Design Value |
|---|---|
| Quadruple Common-Anode Structure | Four independent ESD paths share one anode terminal - reduces PCB area by ~75% vs discrete diodes and eliminates routing complexity for multi-line interfaces |
| Low Capacitance (≤90 pF) | Minimizes signal distortion and timing skew on high-speed digital lines such as USB 2.0 D+/D− and I²C buses |
| High ESD Robustness (>8 kV Contact) | Guarantees survival and functional integrity after repeated IEC 61000-4-2 stress events - extends field reliability in consumer electronics |
| Stable Zener Temperature Coefficient (+2.2 mV/K) | Ensures predictable clamping voltage shift over temperature - simplifies margining for automotive and industrial operating ranges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4-2/TR | Lower working voltage (5.3 V), higher capacitance (120 pF), same SOT353 package and common-anode topology | Better suited for 3.3 V logic protection; less ideal for 5 V tolerant interfaces due to earlier conduction onset | Select when protecting low-voltage microcontroller GPIO banks where tighter clamping margin is required |
| TPD4E05U06DBVR | Higher ESD rating (±15 kV contact), lower capacitance (5.5 pF), but uses different SOT-23-6 package and requires separate ground connections per channel | Superior for ultra-high-speed interfaces (e.g., PCIe Gen3); incompatible pinout prevents drop-in replacement | Choose for next-generation designs prioritizing signal fidelity over footprint compatibility with legacy layouts |
Compared with ESD5V3U4-2/TR and TPD4E05U06DBVR, the BZA868AL,115 delivers optimal balance of 6.8 V clamping headroom, 90 pF capacitance, and proven SOT353 manufacturability - making it preferred for cost-sensitive, high-volume USB and audio applications requiring IEC 61000-4-2 compliance without redesign.

FAQ
What is the working voltage specification for BZA868AL,115?
The BZA868AL,115 has a nominal working voltage (VZ) of 6.8 V at test current IZ = 1 mA, with a guaranteed range of 6.46 V to 7.14 V. This value defines the minimum reverse voltage at which the diode begins conducting significantly, establishing the clamping threshold for protected signal lines. The BZA868AL,115's 6.8 V rating makes it suitable for safeguarding 5 V-tolerant interfaces while maintaining margin above typical logic high levels.
Does BZA868AL,115 meet IEC 61000-4-2 ESD immunity requirements?
Yes, the BZA868AL,115 is rated for >8 kV contact discharge per IEC 61000-4-2, verified through standardized testing using the 150 pF/330 Ω network. Its clamping performance under fast-rising ESD pulses is documented in the datasheet's waveform figures, confirming effective suppression of both positive and negative transients. The BZA868AL,115 achieves this while maintaining low parasitic capacitance - a key factor in real-world system-level compliance.
What is the maximum non-repetitive peak reverse power dissipation for BZA868AL,115?
The BZA868AL,115 has a maximum non-repetitive peak reverse power dissipation (PZSM) of 14 W for a 1 ms square pulse, as specified in the Limiting Values table. This rating reflects the device's ability to absorb transient energy without failure during a single ESD event. The BZA868AL,115's 14 W capability is validated across its operational temperature range and forms the basis for its use in high-reliability consumer and industrial interfaces.
How is the common anode configuration implemented in BZA868AL,115?
The BZA868AL,115 implements a common anode configuration with Pin 2 serving as the shared anode terminal for all four integrated diodes, while Pins 1, 3, 4, and 5 are individual cathodes. This architecture allows four independent signal lines to be protected with a single ground return path, reducing PCB routing complexity and inductance. In practice, the BZA868AL,115's Pin 2 must be connected to a low-impedance system ground plane to ensure effective clamping across all channels.
What thermal resistance values apply to BZA868AL,115 under full-load conditions?
Under full-load conditions (all four diodes active), the BZA868AL,115 exhibits a junction-to-ambient thermal resistance (Rth j-a) of 410 K/W and a junction-to-solder-point thermal resistance (Rth j-s) of 185 K/W. These values assume mounting on a standard PCB per JEDEC JESD51-3 guidelines. The BZA868AL,115's thermal performance directly impacts maximum allowable power dissipation and safe operating temperature - critical for sustained operation in enclosed or high-ambient environments.
