Product details
Overview
SZBZX84C6V2LT3G from onsemi is a 6.2 V ±5% Zener diode in SOT-23 package, rated for 250 mW power dissipation at 25°C, with 10 Ω dynamic impedance at 5 mA test current and 0.4 mV/°C temperature coefficient. It provides precision voltage regulation in space-constrained DC bias and reference circuits for portable electronics.
For engineers reviewing the SZBZX84C6V2LT3G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low dynamic impedance (10 Ω), automotive-grade AEC-Q101 qualification, and Pb-free SOT-23 packaging compatible with high-density automated assembly.
Technical Context
This device operates as a two-terminal voltage reference using controlled reverse-biased avalanche breakdown. Its nominal 6.2 V Zener voltage is specified at 5 mA test current (IZT), with tight thermal stability ensured by a low +0.4 mV/°C temperature coefficient.
The SOT-23 package features an anode-cathode pinout (Pin 1 = Anode, Pin 3 = Cathode, Pin 2 = No Connection) and supports FR-4 board mounting with 250 mW power rating derated linearly above 25°C at 2.0 mW/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8–6.6 V range at IZT = 5 mA - defines stable regulation point for bias/reference networks |
| Power Dissipation | 250 mW on FR-5 board at 25°C - sets maximum continuous DC power handling in standard PCB layouts |
| Zener Impedance (ZZT) | 10 Ω max at IZT = 5 mA - ensures minimal output voltage variation under load current changes |
| Temperature Coefficient | +0.4 mV/°C at IZT = 5 mA - enables predictable voltage drift over −65°C to +150°C junction range |
| Reverse Leakage Current | 3 μA max at VR = 4 V - guarantees low standby power loss in high-impedance sensing paths |
| Capacitance | 185 pF max at VR = 0 V, f = 1 MHz - limits high-frequency noise coupling in filtering applications |
| ESD Rating | Class 3 (>16 kV HBM) - withstands robust handling in manufacturing and field environments |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | DC input terminal for reverse-bias operation; connects to lower-potential node in regulation circuit |
| 2 | No Connection | Internally unconnected; must remain floating - no PCB trace or pad required |
| 3 | Cathode | DC output/reference terminal; connects to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics requiring PPAP compliance |
| Pb-free & RoHS compliant | Meets global environmental regulations without compromising solderability or thermal performance |
| Low dynamic impedance | 10 Ω at 5 mA enables stable reference voltage under varying load conditions in analog sensor interfaces |
| High ESD robustness | Class 3 HBM (>16 kV) eliminates need for external protection in handheld and wearable designs |
| Tight thermal coefficient | +0.4 mV/°C minimizes drift in battery-powered systems operating across wide ambient temperatures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C6V2LT3G | Standard commercial-grade variant; same 6.2 V nominal, ±5% tolerance, 10 Ω ZZT, but lacks AEC-Q101 qualification and automotive PPAP support | Approved for consumer and industrial use only; not suitable for automotive production programs | Select when cost sensitivity outweighs automotive compliance requirements and lifecycle traceability is not mandated |
| SZBZX84C6V2LT1G | Identical electrical specs and AEC-Q101 qualification, but supplied in 3,000-piece tape-and-reel vs. 10,000-piece for LT3G | Same automotive application coverage; differs only in packaging quantity and associated logistics planning | Choose for prototyping, low-volume builds, or where smaller reel size simplifies SMT line changeovers |
Compared with BZX84C6V2LT3G and SZBZX84C6V2LT1G, the SZBZX84C6V2LT3G delivers identical regulation performance and automotive qualification while optimizing for high-volume production via larger reel packaging-reducing line stoppages and material handling overhead without altering circuit design or layout.

FAQ
What is the Zener voltage tolerance of SZBZX84C6V2LT3G?
The SZBZX84C6V2LT3G has a nominal Zener voltage of 6.2 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 5.8 V and 6.6 V when tested at 5 mA (IZT). This tolerance is confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet, and applies across the full operating temperature range of −65°C to +150°C.
Is SZBZX84C6V2LT3G qualified for automotive applications?
Yes, SZBZX84C6V2LT3G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the Features section of the onsemi datasheet. The "SZ" prefix denotes automotive and other applications requiring unique site and control change requirements, and the device meets all stress testing and reliability criteria defined in the AEC-Q101 standard for discrete semiconductors.
What is the pin configuration of SZBZX84C6V2LT3G?
SZBZX84C6V2LT3G uses the SOT-23 package with Pin 1 = Anode, Pin 2 = No Connection (unbonded), and Pin 3 = Cathode, per the Marking Diagram and Mechanical Characteristics section (Style 8) of the datasheet. The cathode is marked by a polarity band on the package body, and Pin 2 must remain unconnected in PCB layout.
What is the maximum power dissipation for SZBZX84C6V2LT3G on FR-5 board?
SZBZX84C6V2LT3G is rated for 250 mW total power dissipation on FR-5 board at TA = 25°C, with linear derating of 2.0 mW/°C above that temperature. This value is listed in the Maximum Ratings table on page 2 of the onsemi datasheet and assumes standard JEDEC-defined board construction (1.0 × 0.75 × 0.62 in.).
Does SZBZX84C6V2LT3G have ESD protection?
Yes, SZBZX84C6V2LT3G has an ESD rating of Class 3 (>16 kV) per Human Body Model (HBM), as documented in the Features section of the datasheet. This level of robustness allows direct handling and placement in high-volume automated assembly without additional ESD mitigation in the signal path.
