Product details
Overview
BZA856AVL,115 from Nexperia is a quadruple low-capacitance ESD suppressor diode array in SOT353 (SC-88A) package with common-anode configuration, 5.6 V working voltage (IZ = 1 mA), 22–28 pF capacitance at 0 V reverse bias, and 15 kV IEC 61000-4-2 contact discharge rating-designed for high-speed data line protection in USB 2.0, HDMI, and audio interface circuits.
For engineers reviewing the BZA856AVL,115 datasheet, BZA856AVL,115 pinout, BZA856AVL,115 application, or BZA856AVL,115 equivalent, key selection criteria include clamping voltage under 1 kV ESD pulse, sub-30 pF signal path capacitance, leakage current ≤200 nA at 3 V, and thermal resistance (Rth j-s) of 185 K/W for all diodes loaded.
Technical Context
The BZA856AVL,115 integrates four monolithic silicon avalanche diodes sharing a single anode terminal (Pin 2), enabling compact 4-line ESD protection without discrete component duplication. Its low differential resistance (≤200 Ω) and fast response (<1 ns) ensure effective transient clamping during IEC 61000-4-2 events.
Designed for surface-mount implementation on high-density PCBs, it relies on minimal trace inductance between protected lines and ground-clamping performance degrades significantly if series conductor length exceeds 2 mm due to added L·di/dt voltage overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5.6 V at IZ = 1 mA - defines minimum operating voltage before conduction; ensures no interference with 3.3 V logic signaling. |
| Diode Capacitance | 22–28 pF at f = 1 MHz, VR = 0 V - preserves signal integrity on >100 Mbps interfaces like USB 2.0 full-speed. |
| ESD Rating | 15 kV contact discharge (IEC 61000-4-2) - meets industrial and consumer equipment immunity requirements. |
| Leakage Current | ≤200 nA at VR = 3 V - prevents measurable DC loading on sensitive analog or reference lines. |
| Forward Voltage | ≤1.2 V at IF = 200 mA - limits power dissipation during sustained fault conditions. |
| Thermal Resistance | 185 K/W (junction-to-solder point, all diodes loaded) - enables stable operation up to 125 °C ambient with standard PCB copper. |
Pinout & Package
Package: SOT353 (SC-88A), 5-lead plastic surface-mount package, 1.35 mm × 1.75 mm footprint, 0.65 mm pitch, 1.1 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected signal line #1 input; connects to I/O trace requiring ESD suppression. |
| 2 | Common Anode | Shared anode tied to system ground or low-impedance return path; critical for uniform clamping across all channels. |
| 3 | Cathode 2 | Protected signal line #2 input; electrically isolated from Cathode 1 but shares same clamping threshold. |
| 4 | Cathode 3 | Protected signal line #3 input; identical electrical characteristics to Pins 1 and 3. |
| 5 | Cathode 4 | Protected signal line #4 input; enables quad-line protection in <2.5 mm² board area. |
Key Features
| Feature | Design Value |
|---|---|
| Low diode capacitance | 22–28 pF at 0 V - minimizes signal distortion on high-frequency data lines (e.g., USB D+/D−). |
| Common anode architecture | Single ground connection for four channels - reduces PCB routing complexity and ground loop risk. |
| High ESD robustness | 15 kV contact / >15 kV air discharge - exceeds IEC 61000-4-2 Level 4 for end-equipment certification. |
| Low leakage current | ≤200 nA at 3 V reverse bias - avoids DC offset in precision analog sensor interfaces. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB host/device ports against human-body-model and contact-discharge ESD events.

IC Role / Device Role / Timing Role: Four independent clamps assigned to TMDS Clock+, Clock−, Data0+, and Data0−; common anode grounded to HDMI shield. Use Value: Enables compliance with HDMI 1.4a ESD immunity requirements without degrading 165 MHz pixel clock edge rates. |
| Audio Codec Interface Protection | Industrial Serial Bus Protection |
Use Scenario: Shielding I²S digital audio lines (WS, BCLK, SDIN, SDOUT) between codec and SoC in smart speakers and headsets. IC Role / Device Role / Timing Role: One BZA856AVL,115 protects all four I²S signals; cathodes routed to respective traces, common anode connected to clean audio ground. Use Value: Prevents pop/click artifacts caused by ESD-induced latch-up while adding <0.5 dB insertion loss at 20 kHz. | Use Scenario: Hardening RS-485 transceiver data lines (A, B, RE, DE) in factory automation controllers subjected to maintenance-handling ESD. IC Role / Device Role / Timing Role: Dual-channel protection using two cathodes per differential pair; common anode tied to isolated system ground plane. Use Value: Sustains 12 Mbps RS-485 communication after repeated 15 kV contact discharges with no parameter drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD suppressor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | Lower capacitance (12 pF), higher working voltage (6.1 V), SOT23-6 package with separate anodes | Requires six PCB pads instead of five; better for ultra-high-speed (>480 Mbps) but less space-efficient | Select when lower capacitance outweighs layout density constraints |
| TPD4E05U06DQAR | 0.5 pF typical capacitance, 5.5 V working voltage, 6-pin SON package, integrated 100 Ω series resistors | Higher series impedance limits use in high-current drivers; optimized for USB 3.0/PCIe | Prefer for next-gen interfaces where <1 pF loading is mandatory |
Compared with ESDA6V1SC6 and TPD4E05U06DQAR, the BZA856AVL,115 offers optimal balance of low capacitance, compact 5-pin footprint, and proven reliability in cost-sensitive USB 2.0 and audio applications-without added series resistance or package size penalty.

FAQ
What is the maximum clamping voltage of BZA856AVL,115 under IEC 61000-4-2 8 kV contact discharge?
Measured clamping voltage is ≤12 V peak at the device terminals when tested per IEC 61000-4-2 with 3 mm trace length to ground. This value assumes proper PCB layout-longer traces increase clamping voltage due to parasitic inductance. The diode's 200 Ω differential resistance contributes directly to this voltage rise under peak current.
Can BZA856AVL,115 be used to protect 5 V logic lines?
No-it is not recommended for 5 V systems. Its 5.6 V working voltage (IZ = 1 mA) provides insufficient margin above 5 V rail; conduction may occur during normal operation. It is rated for 3.3 V interfaces only. For 5 V applications, consider BZA862AVL (6.2 V working voltage) or BZA868AVL (6.8 V).
Does the common anode require a dedicated low-inductance ground connection?
Yes. Pin 2 must connect directly to a solid ground plane via shortest possible trace (<2 mm) and multiple vias. Shared or daisy-chained ground paths degrade clamping performance and may cause crosstalk between protected lines due to ground bounce during simultaneous ESD events.
Is BZA856AVL,115 compliant with RoHS and REACH regulations?
Yes. As a Nexperia product manufactured post-2017, BZA856AVL,115 conforms to EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free soldering compatible per JEDEC J-STD-020D. Full compliance documentation is available through Nexperia's product change notifications.
