Product details
Overview
NZL6V8AXV3T1G from onsemi is a dual common-anode ESD protection diode in SC-89 package, rated for 6.8 V breakdown voltage (VBR = 6.46–7.14 V), 11.9 V clamping voltage (VC) at 1.0 A surge, and 1.0 µA max reverse leakage at 4.5 V VRWM. It delivers Class N ESD protection (>16 kV HBM) and meets IEC61000-4-2 Level 4 for bidirectional or unidirectional line protection in space-constrained I/O interfaces.
For engineers reviewing the NZL6V8AXV3T1G datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (4.5 V), clamping performance under 1.0 A transient, thermal resistance (525 °C/W), low capacitance in bidirectional mode, and compatibility with automated SMT reflow (MSL 1, 260 °C).
Technical Context
This device implements a monolithic dual-junction silicon structure with shared anode (Pin 3) and separate cathodes (Pins 1 & 2), enabling independent protection of two signal lines in one compact SC-89 footprint. Its design supports both unidirectional operation (e.g., data line to ground) and bidirectional configuration (e.g., differential pair), with verified clamping response to 8/20 µs transients per IEC61000-4-2.
The NZL6V8AXV3T1G operates across −55 °C to +150 °C junction temperature, exhibits <1.0 µA leakage at VRWM, and maintains stable VBR over temperature (±0.015%/°C typical). Its 525 °C/W thermal resistance and 240 mW power dissipation rating on FR-5 board define its steady-state surge handling capability without derating below 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 4.5 V - Maximum continuous reverse voltage before significant leakage; sets safe operating margin for 3.3 V or 5 V I/O rails. |
| VBR (min/typ/max) | 6.46 / 6.8 / 7.14 V - Breakdown threshold at 5 mA test current; defines onset of avalanche conduction during ESD events. |
| VC @ IPP = 1.0 A | 11.9 V - Clamping voltage during 8/20 µs surge; limits downstream IC stress during IEC61000-4-2 contact discharge. |
| IR @ VRWM | ≤1.0 µA - Reverse leakage at rated working voltage; ensures minimal signal loading on high-impedance lines. |
| ESD Rating | >16 kV HBM (Class N) - Survives human-body-model discharges without degradation; validated per JESD22-A114. |
| Capacitance | Typ. 30 pF @ 0 V (bidirectional mode) - Low enough for USB 2.0 or UART lines without signal integrity impact. |
| Package | SC-89 (Case 463C, 1.60 × 0.85 × 0.70 mm) - Enables high-density placement on miniaturized PCBs with standard 0.5 mm pitch. |
Pinout & Package
SC-89 package (Case 463C, Style 4) with 3-terminal surface-mount construction: void-free thermosetting epoxy case (UL 94 V-0), 100% matte tin lead finish, MSL 1 rating, and 260 °C max reflow tolerance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Connects to first protected signal line; forms unidirectional path to shared anode (Pin 3) when used alone. |
| Pin 2 | Cathode (Line 2) | Connects to second protected signal line; enables independent protection of two I/O paths with single device. |
| Pin 3 | Common Anode | Shared connection point-typically tied to ground or VCC depending on unidirectional/bidirectional configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single SC-89 | Reduces PCB area by ~50% vs. two discrete SOD-323 diodes; eliminates routing complexity for paired signals. |
| IEC61000-4-2 Level 4 compliance | Withstands ±8 kV contact and ±15 kV air discharge-meets industrial and medical equipment immunity requirements. |
| Low clamping voltage (11.9 V @ 1 A) | Keeps protected ICs within safe absolute maximum ratings during fast transients; critical for 3.3 V logic interfaces. |
| Pb-free, Halogen-free, RoHS-compliant | Meets global environmental regulations and enables use in automotive-qualified supply chains (AEC-Q101 compatible variants available). |
Applications
| USB 2.0 Data Lines | Industrial Serial Interface (RS-232/485) |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between connector and PHY IC. Use Value: 30 pF capacitance avoids signal rise-time degradation; 11.9 V clamping prevents damage to 3.3 V tolerant PHY inputs. | Use Scenario: Safeguarding RS-232 driver/receiver pins in factory automation controllers exposed to cable-induced surges. IC Role / Device Role / Timing Role: Unidirectional clamp (Pin 1→Pin 3 to GND, Pin 2→Pin 3 to GND) on TX/RX lines. Use Value: Dual-cathode architecture allows independent protection without shared impedance; 1.0 µA leakage preserves bus bias stability. |
| Medical Sensor Interface | Point-of-Sale Terminal Keypad |
Use Scenario: Shielding analog front-end inputs of patient-monitoring devices from electrostatic discharge during clinical handling. IC Role / Device Role / Timing Role: Low-leakage unidirectional protector on sensor signal lines referenced to system ground. Use Value: ≤1.0 µA IR ensures no DC offset error in µA-level biopotential measurements; SC-89 fits tight flex-cable connectors. | Use Scenario: ESD hardening of membrane keypad scan lines in retail terminals subject to frequent operator contact. IC Role / Device Role / Timing Role: Common-anode dual clamp tying all row/column lines to chassis ground. Use Value: Single-device dual protection reduces BOM count and assembly cost; >16 kV HBM withstands repeated dry-environment discharges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z6.8T5G | Same SC-89 package, 6.8 V VBR, but single-line configuration (1 cathode/1 anode); 12.5 V VC @ 1 A. | Requires two devices for dual-line protection; higher board area and assembly cost. | Select when layout permits discrete placement or when line isolation demands strict separation. |
| CM1213A-03SO | 3-pin SOT-23, dual common-cathode topology; 6.8 V VBR, 12.0 V VC @ 1 A; 35 pF capacitance. | Common-cathode orientation requires VCC tie instead of GND; higher capacitance may affect high-speed lines. | Prefer when existing designs use SOT-23 footprints or when power-rail referenced clamping is required. |
Compared with ESD5Z6.8T5G and CM1213A-03SO, the NZL6V8AXV3T1G uniquely integrates dual cathodes with a shared anode in SC-89-enabling true single-package, ground-referenced dual-line protection with lowest footprint and leakage, ideal for miniaturized I/O interfaces.

FAQ
What is the exact pin configuration and polarity of NZL6V8AXV3T1G?
The NZL6V8AXV3T1G uses SC-89 Style 4 pinout: Pin 1 is Cathode (Line 1), Pin 2 is Cathode (Line 2), and Pin 3 is the Common Anode. This dual-cathode, single-anode arrangement enables independent protection of two signal lines referenced to a shared node-typically ground in unidirectional mode or VCC in bidirectional configurations. The marking code "L2" appears on the top surface.
Does NZL6V8AXV3T1G meet automotive qualification standards?
The NZL6V8AXV3T1G itself is not AEC-Q101 qualified; however, the pin-compatible automotive-grade variant SZNZL6V8AXV3T1G is explicitly listed as AEC-Q101 qualified and PPAP capable in the same datasheet. For automotive applications requiring certified reliability, SZNZL6V8AXV3T1G-not NZL6V8AXV3T1G-is the designated option.
What is the maximum surge current rating for NZL6V8AXV3T1G?
The NZL6V8AXV3T1G is rated for a peak pulse current (IPP) of 1.0 A under the standardized 8/20 µs waveform defined in IEC61000-4-5. At this current level, its clamping voltage (VC) is guaranteed ≤11.9 V. The datasheet also specifies a maximum IPP of 6.7 A for short-duration pulses, corresponding to a peak power (Ppk) of 73 W.
Can NZL6V8AXV3T1G be used in bidirectional ESD protection mode?
Yes, NZL6V8AXV3T1G supports bidirectional operation by connecting the common anode (Pin 3) to a reference voltage mid-point-such as VCC/2-or using external biasing. In this configuration, both cathodes (Pins 1 & 2) clamp positive and negative transients symmetrically. The datasheet confirms bidirectional mode performance with lower capacitance (~30 pF) versus unidirectional mode.
Is NZL6V8AXV3T1G still in active production?
No-NZL6V8AXV3T1G is marked as discontinued per the official onsemi datasheet revision 8 (September 2025). Page 6 of the datasheet explicitly lists it under "DISCONTINUED" with the note: "These devices are not available. Please contact your onsemi representative for information." Aetrix Electronics offers legacy supply support, including remaining stock and cross-reference guidance.
