Product details
Overview
BZA962AVL,115 from Nexperia is a quadruple low-capacitance ESD suppressor diode array in SOT665 package, configured as common-anode quad TVS for high-speed data line protection. It delivers 6.2 V working voltage (IZ = 1 mA), ≤22 pF capacitance at 0 V, ≤12 pF at 5 V, 100 nA reverse leakage at 4 V, and 15 kV IEC 61000-4-2 contact discharge rating - deployed in USB 2.0, HDMI DDC, and SD card interface protection.
For engineers reviewing the BZA962AVL,115 datasheet, BZA962AVL,115 pinout, BZA962AVL,115 application, or BZA962AVL,115 equivalent, key selection criteria include clamping performance under fast-rising ESD transients, channel-to-channel isolation in multi-line layouts, thermal resistance to solder-point (125 K/W all-diodes loaded), and compatibility with 0.5 mm pitch PCB routing for compact interface protection.
Technical Context
The BZA962AVL,115 integrates four monolithic silicon avalanche diodes in a single common-anode configuration, enabling simultaneous suppression of ESD events across four independent signal lines without cross-talk coupling. Its low differential resistance (150 Ω typ. at IZ = 1 mA) ensures predictable clamping voltage rise under transient current.
Designed for IEC 61000-4-2 Level 4 compliance, it sustains non-repetitive peak reverse currents up to 0.85 A (tp = 1 ms) and peak reverse power up to 6 W, with thermal resistance from junction to solder point specified at 125 K/W when all four diodes are active - critical for sustained surge handling in densely routed PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 6.2 V at IZ = 1 mA - defines minimum trigger threshold before clamping begins on each channel |
| Diode Capacitance | 18–22 pF at 0 V / 9–12 pF at 5 V - enables use on 480 Mbps USB 2.0 and 100 MHz DDC lines without signal integrity loss |
| Reverse Leakage (IR) | ≤100 nA at VR = 4 V - ensures negligible DC loading on high-impedance I²C/SDIO bus lines |
| ESD Rating | 15 kV contact discharge (IEC 61000-4-2) - exceeds industrial immunity requirement for handheld and peripheral interfaces |
| Differential Resistance (rdiff) | 150 Ω max at IZ = 1 mA - determines clamping voltage rise (ΔV = Itransient × rdiff) during fast ESD events |
| Thermal Resistance (Rth j-s) | 125 K/W (all diodes loaded) - sets maximum allowable average power dissipation in continuous multi-pulse scenarios |
Pinout & Package
Supplied in SOT665 - a 5-lead surface-mount plastic package with 0.5 mm lead pitch, optimized for high-density layout and minimal parasitic inductance in ESD protection paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD return path for first protected signal line; connects to I/O trace before connector |
| 2 | Common Anode | Shared anode tied to system ground plane; must be low-inductance connection to minimize clamping overshoot |
| 3 | Cathode 2 | ESD return path for second protected signal line; electrically isolated from Pin 1 |
| 4 | Cathode 3 | ESD return path for third protected signal line; maintains channel independence |
| 5 | Cathode 4 | ESD return path for fourth protected signal line; supports full 4-bit parallel bus protection |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel common-anode topology | Enables compact 4-line protection in single footprint - reduces PCB area vs. discrete diodes by >60% |
| Low capacitance (≤12 pF @ 5 V) | Preserves signal edge rate and eye diagram integrity on 480 Mbps USB 2.0 and 100 MHz DDC buses |
| 15 kV IEC 61000-4-2 contact rating | Meets EN 61000-4-2 Level 4 for end-equipment certification without external shielding |
| 125 K/W junction-to-solder thermal resistance | Supports reliable operation under repeated ESD pulses in thermally constrained embedded modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel ESD suppressor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4-2/TR | Lower working voltage (5.3 V), higher capacitance (30 pF @ 0 V), same SOT665 package | Better suited for 3.3 V logic rails but marginal for 5 V tolerant interfaces due to tighter clamping margin | Select when protecting 3.3 V-only I/O with stricter clamping voltage requirements |
| TPD4E001DPVR | Higher capacitance (15 pF @ 0 V per channel), lower ESD rating (12 kV contact), different 5-pin X2SON package | Requires re-layout due to 0.4 mm pitch and different pad geometry; less robust for industrial-level ESD stress | Prefer only when footprint redesign is acceptable and 12 kV rating suffices |
Compared with ESD5V3U4-2/TR and TPD4E001DPVR, BZA962AVL,115 offers superior 15 kV contact ESD immunity and lower capacitance at operating bias - making it optimal for high-speed, mixed-voltage interfaces where signal fidelity and ruggedness are jointly critical.

FAQ
What is the maximum clamping voltage of BZA962AVL,115 under IEC 61000-4-2 8 kV contact discharge?
Measured clamping voltage is ≤12 V at 8 kV contact discharge (IEC 61000-4-2), based on standard test setup with 150 pF/330 Ω network and 2 ns rise time. This value accounts for both intrinsic diode behavior and typical PCB parasitics when mounted per recommended layout guidelines.
Can BZA962AVL,115 be used to protect 5 V tolerant I/O pins?
Yes - its 6.2 V working voltage (VZ) provides safe margin above 5 V logic rails, and its 15 kV contact ESD rating exceeds industrial immunity requirements. Reverse leakage remains ≤100 nA at 4 V, ensuring no functional interference with 5 V CMOS inputs.
Does the common-anode configuration require special grounding considerations?
Yes - Pin 2 (common anode) must connect directly to a low-inductance system ground plane using short, wide traces. Shared ground paths with noisy power or digital return currents increase clamping overshoot; dedicated ground pour under the SOT665 footprint is strongly recommended.
How does thermal derating affect BZA962AVL,115 in multi-pulse ESD environments?
At 85 °C ambient, total power dissipation drops to ~200 mW (per Fig.5 derating curve). For repetitive ESD events (>1 Hz), average power must stay below this limit; the 125 K/W Rth j-s (all diodes) enables safe operation if PCB copper area around Pin 2 exceeds 100 mm².
