Product details
Overview
SZBZX84C6V2LT1 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 6 µA reverse leakage at 4.7 V, used for voltage regulation and overvoltage protection in portable power rails.
For engineers reviewing the SZBZX84C6V2LT1 datasheet, pinout, applications, or equivalent options, key selection factors include Zener voltage tolerance (±5%), thermal resistance (500 °C/W), ESD rating (>16 kV HBM), junction temperature range (−65 to +150°C), and automotive qualification per AEC-Q101.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage across its cathode-anode terminals. Its Zener voltage is specified at three test currents (1 mA, 5 mA, 20 mA), with temperature coefficient of +0.4 mV/°C at 5 mA - indicating positive drift above 6 V nominal.
The SOT-23 package features a no-connect terminal (Pin 2), enabling mechanical stability without electrical function. It supports automated placement and reflow soldering up to 260°C for 10 seconds, with UL 94 V-0 flammability rating and Pb-free/RoHS-compliant construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 6.2 V nominal, min 5.8 V / max 6.6 V at 5 mA - defines clamping threshold for precision regulation |
| Power Dissipation | 250 mW on FR-5 board at 25°C - sets maximum continuous power handling before thermal derating |
| Zener Impedance | 10 Ω at 5 mA - determines output voltage variation under load current changes |
| Reverse Leakage | 6 µA at VR = 4.7 V - indicates off-state current in regulation mode below breakdown |
| Temp Coefficient | +0.4 mV/°C at 5 mA - quantifies voltage drift with ambient temperature change |
| Capacitance | 185 pF at VR = 0 V, f = 1 MHz - affects high-frequency noise filtering and transient response |
| ESD Rating | Class 3 (>16 kV) per HBM - ensures robustness against electrostatic discharge during handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C6V2LT1G | Same Zener voltage, tolerance, and SOT-23 package but non-automotive grade; no AEC-Q101 qualification | Lacks PPAP capability and automotive traceability; suitable for commercial-grade consumer products only | Select if cost sensitivity outweighs automotive compliance requirements |
| SZBZX84B6V2LT1G | Tighter ±1% Zener tolerance (vs. ±5%), same 6.2 V nominal, identical SOT-23 footprint and AEC-Q101 qualification | Higher precision enables tighter regulation margins in feedback loops or reference circuits | Choose when voltage accuracy is critical and budget allows premium tolerance grade |

FAQ
What is the Zener voltage tolerance of SZBZX84C6V2LT1?
The SZBZX84C6V2LT1 has a Zener voltage tolerance of ±5% at 5 mA test current, meaning its actual breakdown voltage falls between 5.8 V and 6.6 V under standard conditions. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the official datasheet. The SZBZX84C6V2LT1 is part of the standard-tolerance C-series, distinguishing it from the tighter ±1% B-series variants like SZBZX84B6V2LT1G.
Is SZBZX84C6V2LT1 qualified for automotive use?
Yes, SZBZX84C6V2LT1 is AEC-Q101 qualified and PPAP capable, as explicitly stated in the "Features" section of the datasheet. The "SZ" prefix denotes automotive and other applications requiring unique site and control change requirements. This makes the SZBZX84C6V2LT1 suitable for under-hood and cabin electronics where reliability across −40°C to +125°C junction temperature is required.
What is the thermal resistance of SZBZX84C6V2LT1 on FR-5 board?
The thermal resistance, junction-to-ambient (RJA), of SZBZX84C6V2LT1 is 500 °C/W when mounted on an FR-5 board, as specified in the Maximum Ratings table. This value applies at 25°C ambient and assumes standard 1.0 × 0.75 × 0.62 inch board dimensions. Derating is 2.0 mW/°C above 25°C, limiting usable power at elevated temperatures.
Does SZBZX84C6V2LT1 have a no-connect pin, and how should it be handled?
Yes, SZBZX84C6V2LT1 uses Pin 2 as a no-connect terminal, as confirmed in the Pinout diagrams on pages 2 and 3 of the datasheet. This terminal serves only mechanical support and must remain unconnected in PCB layout and schematic symbol. Routing traces or applying solder paste to Pin 2 may cause assembly defects or unintended parasitic coupling.
What is the maximum reverse leakage current for SZBZX84C6V2LT1?
The maximum reverse leakage current for SZBZX84C6V2LT1 is 6 µA at VR = 4.7 V, per the Electrical Characteristics table on page 3. This parameter reflects off-state conduction prior to Zener breakdown and is critical for low-power standby circuits. At 25°C ambient, leakage remains well below 10 µA, supporting ultra-low-quiescent-current designs.
