Product details
Overview
BZA856A,115 from Nexperia is a quadruple ESD transient voltage suppressor diode in SOT353 (SC-88A) package with common anode configuration, 5.6 V nominal working voltage (IZ = 1 mA), <240 pF capacitance at 0 V, and >8 kV IEC 61000-4-2 ESD rating - used for high-speed data line protection in USB, HDMI, and audio interfaces.
For engineers reviewing the BZA856A,115 datasheet, BZA856A,115 pinout, BZA856A,115 application, or BZA856A,115 equivalent, key selection criteria include clamping voltage under 1 kV ESD pulse, low diode capacitance for signal integrity, common-anode 4-channel topology, and thermal resistance of 370 K/W for board-level transient energy dissipation.
Technical Context
The BZA856A,115 integrates four monolithic Zener-based ESD protection diodes sharing a single anode terminal, enabling compact 4-line suppression without discrete routing. Its design targets fast transient response (sub-nanosecond clamping), low leakage (<2 µA at 3 V), and stable VZ across temperature (−0.2 mV/K TC).
It operates within a −65 °C to +150 °C storage range and supports non-repetitive peak reverse current up to 3.2 A (1 ms pulse), with PZSM = 24 W and differential resistance ≤400 Ω - optimized for I/O port protection where parasitic inductance must be minimized via short PCB traces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 5.6 V @ IZ = 1 mA - sets clamping threshold for 3.3 V logic lines without false triggering. |
| ESD Rating | >8 kV contact discharge per IEC 61000-4-2 - meets industrial and consumer ESD immunity requirements. |
| Diode Capacitance (Cd) | 240 pF @ f = 1 MHz, VR = 0 - low enough for USB 2.0 (480 Mbps) and audio DAC/ADC lines. |
| Reverse Leakage (IR) | 2000 nA @ VR = 3 V - ensures minimal signal loading on high-impedance analog or digital inputs. |
| Differential Resistance (rdiff) | 400 Ω @ IZ = 1 mA - defines dynamic impedance during clamping, directly affecting clamped voltage rise. |
| Thermal Resistance (Rth j-a) | 370 K/W - determines power derating above 25 °C ambient; limits continuous dissipation to ~335 mW. |
Pinout & Package
SOT353 (SC-88A) surface-mount package: 5-lead, plastic, gull-wing leads; dimensions 2.2 mm × 1.8 mm × 1.15 mm (L × W × H); moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD path for Line 1; connects to protected signal trace before connector. |
| 2 | Common Anode | Shared return path to ground plane; must be routed with minimal inductance to GND. |
| 3 | Cathode 2 | ESD path for Line 2; electrically isolated from Cathode 1 but shares same VZ and rdiff. |
| 4 | Cathode 3 | ESD path for Line 3; enables 4-line protection in single footprint, reducing PCB area by ~75% vs. discrete diodes. |
| 5 | Cathode 4 | ESD path for Line 4; all cathodes exhibit matched VZ tolerance (±5%) and capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Quadruple Common-Anode Topology | Four independent ESD paths share one grounded anode - simplifies layout and reduces ground loop risk in multi-signal interfaces. |
| Low Clamping Voltage | Clamps ≤1 kV under ±1 kV IEC 61000-4-2 pulse - protects 3.3 V CMOS I/O from latch-up or gate oxide damage. |
| Matched Diode Parameters | All four diodes share identical VZ, Cd, and rdiff within datasheet tolerances - ensures uniform protection across parallel data lines. |
| High Peak Power Handling | 24 W non-repetitive peak reverse power (1 ms pulse) - absorbs full ESD event energy without degradation. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting USB D+ and D− lines, VBUS detection, and ID pin against contact ESD in portable docking stations. IC Role / Device Role / Timing Role: ESD transient voltage suppressor providing bidirectional clamping between signal lines and ground.

IC Role / Device Role / Timing Role: Transient suppressor on excitation, sense+, sense−, and reference lines - all referenced to system ground. Use Value: 370 K/W Rth j-a allows operation at 85 °C ambient with full derating; 3.2 A IZSM handles induced surges in noisy factory environments. |
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 capacitance (12 pF), higher VZ (6.1 V), SOT23-6 package with separate anodes. | Preferred for high-speed serial links (e.g., PCIe, SATA) where sub-15 pF is mandatory; not suitable for shared-ground 4-line layouts. | Select when signal bandwidth >1 GHz and individual anode routing is acceptable. |
| TPD4E001DPYR | 0.5 pF typical Cd, 5.5 V VBR, quad-channel with independent anodes in X2SON-8. | Optimized for ultra-high-speed interfaces (e.g., MIPI D-PHY); lacks common-anode simplicity for cost-sensitive 3.3 V I/O. | Choose for RF-sensitive or >1 Gbps applications where 240 pF would degrade eye diagram. |
Compared with ESDA6V1SC6 and TPD4E001DPYR, BZA856A,115 trades ultra-low capacitance for layout simplicity and cost efficiency in 4-line, moderate-speed interfaces - delivering optimal balance of ESD robustness, signal fidelity, and PCB real estate usage.

FAQ
What is the maximum clamping voltage of BZA856A,115 under IEC 61000-4-2 ±8 kV contact discharge?
The BZA856A,115 does not specify a single "maximum clamping voltage" value in its datasheet, but measured waveforms show clamped voltage ≤1 kV for ±1 kV IEC 61000-4-2 pulses. Actual clamping depends on PCB layout inductance and pulse rise time; typical clamping is 9–12 V above VZ at IPP = 3.2 A.
Can BZA856A,115 be used for 5 V logic lines?
No - its 5.6 V nominal working voltage makes it unsuitable for reliable 5 V rail protection. At 5 V, leakage increases significantly and clamping margin shrinks; use BZA820A (20 V VZ) or PESD5V0S1BA for 5 V systems.
Is the common anode pin (Pin 2) internally bonded to all four diodes' anodes?
Yes - Pin 2 is the sole internal connection point for all four anodes. This monolithic common-anode structure is confirmed in the device marking diagram, pinning table, and simplified schematic in the Nexperia datasheet (Fig.1 and page 3).
Does BZA856A,115 require external series resistors for USB data line protection?
No - it is designed for direct placement between signal and ground. However, a 0 Ω or low-value (e.g., 10 Ω) resistor may be added in series to limit peak current during extreme transients; this is layout-dependent and not required for standard IEC 61000-4-2 compliance.
