Product details
Overview
SZBZX84C5V6LT1 from onsemi is a 5.6 V ±5% Zener voltage regulator diode in SOT-23 package, rated for 250 mW power dissipation on FR-5 board at 25°C, with 40 Ω dynamic impedance at 5 mA test current and −2.0 mV/°C temperature coefficient - used for precision voltage reference and overvoltage protection in portable power rails.
For engineers reviewing the SZBZX84C5V6LT1 datasheet, pinout, applications, or equivalent options, key selection factors include Zener tolerance (±5%), low leakage (<1 µA @ 4.2 V), ESD robustness (>16 kV HBM), thermal coefficient stability, and SOT-23 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference, conducting in reverse breakdown to clamp voltage across its cathode-anode terminals. It exhibits a nominal Zener voltage of 5.6 V at 5 mA test current (IZT), with guaranteed minimum/maximum values of 5.2 V and 6.0 V respectively.
Its electrical behavior is defined by tight thermal coefficient control (−2.0 mV/°C), low dynamic impedance (40 Ω max at IZT = 5 mA), and minimal capacitance (200 pF at 0 V bias, 1 MHz), enabling stable regulation in low-noise analog and mixed-signal supply monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V range @ 5 mA - sets precise clamping threshold for 5 V rail protection |
| Power Dissipation | 250 mW on FR-5 board @ 25°C - supports compact thermal design without heatsinking |
| Zener Impedance (ZZT) | ≤40 Ω @ 5 mA - ensures minimal voltage shift under load transients |
| Temp Coefficient (TC) | −2.0 mV/°C @ 5 mA - enables predictable drift compensation in automotive ambient ranges |
| Reverse Leakage (IR) | <1 µA @ 4.2 V - preserves low quiescent current in battery-powered standby modes |
| Capacitance (C) | 200 pF @ 0 V, 1 MHz - avoids signal integrity issues in high-frequency feedback paths |
| ESD Rating | Class 3 (>16 kV HBM) - withstands handling and system-level ESD events without degradation |
Pinout & Package
SOT-23 plastic surface-mount package (Case 318, Style 8), void-free thermosetting body with corrosion-resistant finish, Pb-free and RoHS compliant. Maximum soldering temperature: 260°C for 10 seconds. Cathode indicated by polarity band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Connected to lower-potential node (e.g., ground or return path); reverse-biased operation requires this terminal to be at lower voltage than cathode |
| 2 | No Connection | Internally unconnected; must remain floating - no PCB trace or pad tie required |
| 3 | Cathode | Connected to regulated voltage node (e.g., 5 V rail); conducts when cathode-to-anode voltage exceeds 5.6 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTOL, and ESD stress per automotive qualification protocol |
| Tight thermal coefficient | −2.0 mV/°C enables <±15 mV total drift over −40°C to +125°C ambient - suitable for engine control module references |
| Pb-free & RoHS compliant | Meets global environmental compliance mandates without compromising solderability or long-term intermetallic stability |
| Optimized SOT-23 footprint | 0.95 mm max height and 2.9 mm × 1.3 mm body enables placement in ≤0.5 mm pitch routing zones on HDI mobile PCBs |
| High ESD immunity | Class 3 HBM rating (>16 kV) eliminates need for external TVS in many consumer USB and sensor interface applications |
Applications
| USB Power Rail Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Clamping transient spikes on 5 V USB VBUS lines during hot-plug or ESD events. IC Role / Device Role / Timing Role: Two-terminal shunt regulator acting as passive voltage clamp between VBUS and GND.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C5V6LT1G | Same Zener voltage (5.6 V), ±5% tolerance, identical SOT-23 package and pinout - but standard industrial grade (non-AEC-Q101) | Lacks automotive qualification; not approved for under-hood or safety-critical modules | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| SZBZX84B5V6LT1G | Tighter tolerance (±1%) at same 5.6 V nominal, identical AEC-Q101 qualification and SOT-23 package | Higher precision required for reference-grade analog circuits where ±5% variation is unacceptable | Select when voltage accuracy tighter than ±5% is mandated, accepting slightly higher unit cost |
Compared with BZX84C5V6LT1G, SZBZX84C5V6LT1 offers automotive qualification without sacrificing electrical specs; compared with SZBZX84B5V6LT1G, it trades ±1% tolerance for lower cost while retaining AEC-Q101 compliance - making it optimal for cost-sensitive automotive subsystems needing proven reliability but not ultra-tight regulation.

FAQ
What is the maximum power dissipation of SZBZX84C5V6LT1 on an FR-5 board?
SZBZX84C5V6LT1 has a maximum power dissipation of 250 mW on FR-5 board at 25°C ambient temperature, derating linearly by 2.0 mW/°C above that temperature. This rating assumes standard JEDEC-defined board layout conditions and defines the upper thermal limit for continuous DC operation without exceeding junction temperature limits.
Does SZBZX84C5V6LT1 have automotive qualification?
Yes, SZBZX84C5V6LT1 is AEC-Q101 qualified and PPAP capable, with manufacturing site and process controls meeting automotive quality requirements. The "SZ" prefix explicitly denotes devices built to automotive standards, distinguishing them from standard "BZX84C" variants intended for commercial applications.
What is the Zener voltage tolerance for SZBZX84C5V6LT1?
SZBZX84C5V6LT1 has a Zener voltage tolerance of ±5% around its nominal 5.6 V rating, meaning the actual measured VZ falls between 5.2 V and 6.0 V when tested at 5 mA (IZT) and 25°C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the official datasheet.
How is the pinout configured for SZBZX84C5V6LT1?
SZBZX84C5V6LT1 uses the standard SOT-23 pinout: Pin 1 is Anode, Pin 2 is No Connection (internally unconnected and must remain floating), and Pin 3 is Cathode. The cathode is marked by a polarity band on the package body, and reverse-bias operation requires the cathode to be at higher potential than the anode.
What is the ESD rating of SZBZX84C5V6LT1?
SZBZX84C5V6LT1 has an ESD rating of Class 3 per Human Body Model (HBM), corresponding to >16 kV. This rating is verified per AEC-Q101 test requirements and reflects robustness against electrostatic discharge during handling, assembly, and end-use in environments such as automotive cabins or industrial control panels.
