Product details
Overview
BZA956AVL,115 from Nexperia is a quadruple low-capacitance ESD suppressor diode in SOT665 package with common-anode configuration, 5.6 V working voltage (IZ = 1 mA), 22 pF typical capacitance at 1 MHz/0 V, and 15 kV IEC 61000-4-2 contact discharge rating - deployed for high-speed data line protection in USB, HDMI, and audio interfaces.
For engineers reviewing the BZA956AVL,115 datasheet, BZA956AVL,115 pinout, BZA956AVL,115 application, or BZA956AVL,115 equivalent, key selection criteria include clamping voltage under 1 kV ESD pulse, sub-25 pF signal-line capacitance, common-anode 4-channel integration, and thermal resistance of 125 K/W (all diodes loaded) for PCB-level transient suppression design.
Technical Context
The BZA956AVL,115 integrates four monolithic Zener-based ESD protection diodes sharing a single anode terminal (Pin 2), enabling compact 4-line protection without discrete component duplication. Its low differential resistance (≤200 Ω) and fast response ensure clamping within nanoseconds during IEC 61000-4-2 transients.
Designed for signal integrity preservation, it delivers 12–17 pF capacitance at 5 V reverse bias - critical for maintaining eye diagram margins in 480 Mbps USB 2.0 and 1080p video links. Thermal performance is optimized via solder-point thermal path (Rth j-s = 125 K/W all diodes loaded) to sustain repeated ESD events without junction overheating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 5.6 V @ IZ = 1 mA - defines minimum operating voltage threshold before clamping activation |
| Diode Capacitance | 22 pF typ @ 1 MHz / 0 V - ensures minimal signal distortion on high-speed digital lines |
| ESD Rating | 15 kV contact discharge (IEC 61000-4-2) - meets Level 4 immunity for industrial/commercial end equipment |
| Leakage Current (IR) | 200 nA max @ VR = 3 V - prevents DC loading on sensitive analog or reference inputs |
| Differential Resistance (rdif) | 200 Ω max @ IZ = 1 mA - determines dynamic clamping voltage rise under fast transients |

Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|
|
Use Scenario: Protecting D+ and D− differential pairs in host/device USB ports against user-handling ESD events. IC Role / Device Role / Timing Role: Clamp-mode ESD suppressor placed directly at connector, with cathodes tied to D+/D− and common anode grounded. Use Value: 22 pF capacitance avoids signal integrity degradation at 480 Mbps; 15 kV rating exceeds USB-IF compliance requirements. |
Use Scenario: Shielding TMDS clock and data channels (3 data + 1 clock) from ESD during cable insertion in consumer AV gear. IC Role / Device Role / Timing Role: Four-channel suppressor assigned to TMDS+/- pairs and clock pair, minimizing inter-pair skew via matched layout. Use Value: Matched 12–17 pF capacitance at 5 V bias maintains differential impedance and reduces jitter accumulation. |
| Industrial Keypad Interface | Audio Codec Line Protection |
|
Use Scenario: Safeguarding matrix-scanned keypad lines (row/column) in factory HMIs exposed to frequent operator contact. IC Role / Device Role / Timing Role: Common-anode configuration routes all keypad scan lines through individual cathodes while sharing one ground return. Use Value: 200 nA leakage prevents false key detection; 5.6 V working voltage aligns with 3.3 V or 5 V logic supply rails. |
Use Scenario: Protecting line-out, mic-in, and headphone outputs in portable media players from jack-insertion ESD. IC Role / Device Role / Timing Role: Suppresses transients on unbalanced analog audio paths without introducing audible noise or DC offset. Use Value: Low 1.2 V forward voltage ensures no clipping during normal signal swing; 22 pF avoids high-frequency roll-off in 20 kHz bandwidth. |
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 capacitance (12 pF typ @ 0 V), higher working voltage (5.3 V), SOT-25 package (3.0 × 1.75 mm) | Requires larger PCB area; better suited for >1 Gbps interfaces but less optimal for tight USB 2.0 layouts | Select when lower capacitance outweighs footprint constraints and 5.3 V clamping is acceptable |
| TPD4E001DPWR | 0.5 pF lower typical capacitance (21.5 pF), same 5.6 V VZ, but higher leakage (500 nA max) and SOIC-14 package (8.65 × 3.9 mm) | SOIC-14 requires significantly more board space and lacks SOT665's thermal efficiency (Rth j-a = 200 K/W) | Prefer only if legacy SOIC assembly infrastructure exists and leakage tolerance permits |
Compared with ESD5V3U4-2/TR and TPD4E001DPWR, the BZA956AVL,115 offers best-in-class area efficiency (1.7 × 1.5 mm), balanced leakage/capacitance trade-off, and superior thermal dissipation - making it optimal for space-constrained, high-reliability USB and audio designs where layout density and repeatable ESD survival are critical.

FAQ
What is the exact working voltage specification for BZA956AVL,115?
The BZA956AVL,115 has a working voltage (VZ) of 5.6 V nominal at IZ = 1 mA, with a guaranteed range of 5.32 V to 5.88 V. This value defines the DC voltage threshold at which the diode begins conducting significantly during overvoltage events - critical for ensuring protection activates before downstream ICs exceed absolute maximum ratings. The BZA956AVL,115 maintains this specification across its full operating temperature range.
Does BZA956AVL,115 support IEC 61000-4-2 Level 4 ESD immunity?
Yes, the BZA956AVL,115 is rated for 15 kV contact discharge per IEC 61000-4-2 - exceeding Level 4 (8 kV contact / 15 kV air) requirements. This rating is verified under standardized test conditions using the specified 150 pF/330 Ω network. The BZA956AVL,115 achieves this performance while maintaining low clamping voltage due to its 200 Ω max differential resistance and optimized silicon structure.
What is the thermal resistance of BZA956AVL,115 when all four diodes are active?
The BZA956AVL,115 has a thermal resistance from junction to ambient (Rth j-a) of 370 K/W and from junction to solder point (Rth j-s) of 125 K/W when all four diodes are loaded. This Rth j-s value reflects direct heat conduction from the common anode (Pin 2) to the PCB copper pour, enabling reliable handling of repetitive 1 ms ESD pulses without thermal runaway - a key advantage of the SOT665 package over smaller alternatives.
Can BZA956AVL,115 be used to protect analog audio signals without degrading sound quality?
Yes, the BZA956AVL,115 is suitable for analog audio line protection due to its 22 pF typical capacitance at 0 V and only 200 nA max leakage at 3 V reverse bias - both values prevent high-frequency attenuation and DC offset errors. Its 1.2 V forward voltage ensures no clipping occurs during normal ±1 V audio swings. The BZA956AVL,115 has been validated in line-out and mic-in paths of portable audio devices meeting THD+N < 0.01%.
How does the common-anode configuration of BZA956AVL,115 affect PCB layout?
The common-anode configuration of BZA956AVL,115 requires tying Pin 2 to a low-inductance ground plane, with each cathode (Pins 1, 3, 4, 5) routed individually to its protected signal line. This minimizes shared transient return paths and avoids ground bounce between channels. Layout best practice mandates placing the BZA956AVL,115 within 3 mm of the connector and using short, direct traces - a requirement explicitly validated in Nexperia's application notes for microprocessor bus protection.
