Product details
Overview
SZBZX84B6V2LT1G from onsemi is a 6.2 V ±1.9% tight-tolerance 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 3.7 pF capacitance at 0 V bias - used for precision voltage reference and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the SZBZX84B6V2LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±1.9%), low dynamic impedance (10 Ω), AEC-Q101 qualification, Pb-free SOT-23 packaging, and ESD robustness (>16 kV HBM).
Technical Context
This device operates as a two-terminal voltage reference diode with reverse-biased Zener breakdown at 6.2 V nominal. Its tight 1.9% tolerance (6.08–6.32 V) and low 10 Ω Zener impedance at 5 mA enable stable regulation under varying load conditions in low-power analog circuits.
Designed for surface-mount assembly on FR-4/FR-5 PCBs, it features a cathode-marked SOT-23 package (Case 318, Style 8), with pin 1 = anode, pin 2 = no connection, pin 3 = cathode - supporting automated placement and reflow compatibility per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 6.2 V nominal, 6.08–6.32 V range at 5 mA - ensures precise voltage clamping in feedback loops and reference circuits |
| Power Dissipation | 250 mW on FR-5 board at 25°C - supports continuous operation in battery-powered sensor nodes and wearables |
| Zener Impedance | 10 Ω max at IZT = 5 mA - minimizes output voltage variation under dynamic load transients |
| Reverse Leakage | 3 µA max at VR = 3 V - maintains low quiescent current in always-on monitoring circuits |
| Capacitance | 3.7 pF at VR = 0 V, f = 1 MHz - enables use in high-frequency signal conditioning without parasitic loading |
| Temp Coefficient | +0.4 mV/°C at 5 mA - provides near-zero drift across −55°C to +150°C operating range |
| ESD Rating | Class 3 (>16 kV) per HBM - withstands handling and board-level electrostatic discharge in manufacturing |
Pinout & Package
SOT-23 (TO-236) plastic surface-mount package, 2.90 × 1.30 × 1.00 mm, void-free thermosetting case with corrosion-resistant finish; polarity indicated by cathode band; RoHS-compliant and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Connected to lower-potential node in reverse-bias configuration; must be held at voltage ≤ cathode minus 6.2 V to activate regulation |
| 2 | No Connection | Internally unconnected terminal - must remain floating; no PCB trace or pad required |
| 3 | Cathode | Connected to regulated output or higher-potential rail; polarity band on package identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| Tight voltage tolerance | ±1.9% (6.08–6.32 V) - reduces need for external trimming in precision references |
| Low dynamic impedance | 10 Ω at 5 mA - improves regulation accuracy under load changes in power supply feedback paths |
| AEC-Q101 qualified | Validated for automotive applications including body control modules and infotainment power rails |
| Pb-free & RoHS compliant | Meets global environmental directives and lead-free reflow soldering requirements (260°C/10 s) |
