Product details
Overview
QZX363C6V8-7-F from Diodes Incorporated is a quad surface-mount Zener diode array with nominal 6.8 V Zener voltage (5.0 mA test current), 15 Ω maximum Zener impedance, 2.0 µA maximum reverse leakage at 5.0 V, ±4.5 mV/°C temperature coefficient, and 200 mW power dissipation in SOT363 package-used for precision voltage reference and transient suppression in low-power analog signal conditioning circuits.
For engineers reviewing the QZX363C6V8-7-F datasheet, QZX363C6V8-7-F pinout, QZX363C6V8-7-F application, or QZX363C6V8-7-F equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (625 °C/W), junction-to-ambient derating curve, and SOT363 terminal layout compatibility with high-density PCB designs.
Technical Context
This device integrates four independent Zener diodes in a single SOT363 package, each rated for 6.8 V nominal breakdown at 5.0 mA. It operates across –65 °C to +150 °C and exhibits 1.2 to 4.5 mV/°C temperature coefficient, enabling stable regulation in ambient-varying environments.
The array supports transient suppression via clamping action with 200 mW total power dissipation and 15 Ω dynamic impedance at IZT, ensuring predictable voltage limiting under fast-rising ESD or surge events without latch-up or thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage @ 5mA | 6.8 V nominal, 6.47–7.14 V range - defines precise clamping threshold for overvoltage protection |
| Zener Impedance | 15 Ω max at 5mA - ensures minimal voltage shift under load variation |
| Reverse Leakage | 2.0 µA max at 5.0 V - guarantees low quiescent current in standby bias networks |
| Temp Coefficient | +1.2 to +4.5 mV/°C - enables predictable drift compensation in temperature-sensitive references |
| Power Dissipation | 200 mW - sets maximum continuous clamping energy before thermal derating applies |
| Package | SOT363 - provides 0.006 g weight and 2.15 mm × 2.10 mm footprint for space-constrained layouts |
| Operating Temp | –65 °C to +150 °C - supports automotive under-hood and industrial control environments |
Pinout & Package
SOT363 is a 6-pin ultra-small plastic package with dual-row gull-wing leads; pin 1 marked by notch or bevel, body dimensions 2.15 mm × 2.10 mm × 1.00 mm, moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 (C2) | Cathode of Diode 1 | Provides 6.8 V clamping node for input signal rail protection |
| 3 (NC) | No Connect | Internally unconnected; must remain floating or tied to ground per layout guidelines |
| 4 (C3) | Anode of Diode 2 | Shared anode configuration allows common-cathode referencing in dual-rail designs |
| 5 (C4) | Cathode of Diode 2 | Second independent 6.8 V clamp output, electrically isolated from C2 |
| 6 (A) | Anode of Diodes 3 & 4 | Common anode terminal for remaining two Zeners-enables compact multi-rail biasing |
Key Features
| Feature | Design Value |
|---|---|
| Quad Zener integration | Four independent 6.8 V Zener elements in one SOT363 footprint-reduces board area vs. discrete solutions |

Applications
| Industrial Sensor Signal Conditioning | USB Port ESD Protection |
|---|---|
Use Scenario: Protecting 0–5 V analog outputs of pressure and temperature transducers from induced transients on long cable runs. IC Role / Device Role / Timing Role: Zener clamp placed between sensor output and ADC input to limit voltage excursions to ≤7.14 V. Use Value: Prevents ADC saturation and input-stage damage while maintaining <15 Ω dynamic impedance for signal fidelity. | Use Scenario: Safeguarding USB 2.0 D+ and D− lines against electrostatic discharge during hot-plug events. IC Role / Device Role / Timing Role: Dual-diode pair (C1/C2 and C3/C4) clamps both data lines to 6.8 V relative to GND. Use Value: Meets IEC 61000-4-2 Level 4 (8 kV contact) without adding series resistance that degrades signal integrity. |

IC Role / Device Role / Timing Role: Single QZX363C6V8-7-F provides dual-rail clamping (VBAT and LIN) using shared-anode (pin 6) architecture. Use Value: Reduces component count by 50% vs. dual-SOT23 solution while maintaining AEC-Q200-relevant thermal margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235BS-7-F | Single 6.8 V Zener in SOT323; 100 mW rating; 10 Ω ZZT | Requires four separate placements; lacks integrated quad topology | Preferred when board area is unconstrained and individual trimming per channel is needed |
| ASZ363C6V8T | Same SOT363 quad format; 6.8 V nominal; 20 Ω ZZT; 250 mW PD | Higher power rating but wider Zener tolerance (±6%) and +5.0 mV/°C TC | Chosen when higher surge energy handling is prioritized over tight voltage stability |
Compared with MMBZ5235BS-7-F, QZX363C6V8-7-F saves 75% PCB area and eliminates inter-trace coupling risk; versus ASZ363C6V8T, it trades 50 mW headroom for tighter 5% voltage tolerance and lower temperature drift-critical in precision reference designs.

FAQ
What is the maximum reverse current specification for QZX363C6V8-7-F at 5.0 V?
The maximum reverse current (IR) is 2.0 µA at VR = 5.0 V and TA = +25 °C, measured per DS30143 Rev. 14–2. This value confirms low standby power consumption in bias networks and ensures minimal loading on high-impedance source nodes.
Can QZX363C6V8-7-F be used in place of a single Zener diode like BZX84-C6V8?
No-it is a quad array with fixed internal connections (C1/C2, C3/C4, and shared anode on pin 6). Replacing a single Zener requires verifying pin mapping and isolation; direct substitution is invalid unless the circuit explicitly uses all four elements in matched-pair or common-anode configurations.
Does QZX363C6V8-7-F meet AEC-Q200 stress testing requirements?
Diodes Incorporated does not list AEC-Q200 qualification for this part. Its operating temperature range (–65 °C to +150 °C) and construction align with automotive under-hood environments, but formal qualification status must be confirmed via Diodes' official automotive product documentation-not inferred from datasheet parameters alone.
How is the "-7-F" suffix interpreted in the part number QZX363C6V8-7-F?
The "-7" denotes 3000-unit tape-and-reel packaging per EIA-481 standard; "-F" indicates full RoHS 3 compliance (lead-free, halogen-free, antimony-free). This suffix does not affect electrical characteristics but defines mechanical handling and regulatory conformance for automated assembly.
