Product details
Overview
SZBZX84C5V6LT1G 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 SZBZX84C5V6LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener tolerance (±5%), low leakage (≤1 μA @ 4.5 V), automotive-grade AEC-Q101 qualification, Pb-free RoHS compliance, 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 at 5.6 V nominal with tight regulation across 1–20 mA Zener test currents. Its thermal coefficient of −2.0 mV/°C ensures predictable drift in automotive ambient ranges (−65°C to +150°C).
The SOT-23 package features cathode-indicated polarity band, void-free thermoset plastic case, UL 94 V-0 flammability rating, and 260°C/10s soldering tolerance - optimized for automated placement and reflow on FR-4/FR-5 substrates.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C5V6LT1G | Standard industrial-grade variant; same 5.6 V ±5%, 40 Ω ZZT, but lacks AEC-Q101 qualification and automotive PPAP support | Not approved for automotive production; suitable for consumer or industrial non-safety-critical use | Select when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs automotive traceability needs |
| SZBZX84B5V6LT1G | Tighter 1% Zener tolerance (5.49–5.71 V), same −2.0 mV/°C TC and 40 Ω ZZT, identical SOT-23 package | Used where absolute voltage accuracy matters more than cost - e.g., precision analog calibration circuits | Choose when system-level calibration requires sub-30 mV total error budget across temperature and unit-to-unit variation |
Compared with BZX84C5V6LT1G, SZBZX84C5V6LT1G adds automotive qualification and supply-chain controls without sacrificing electrical performance; compared with SZBZX84B5V6LT1G, it trades tighter tolerance for broader voltage margin and lower unit cost in volume automotive deployments.

Yes, SZBZX84C5V6LT1G 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 - making SZBZX84C5V6LT1G suitable for engine control, body electronics, and ADAS power domains.
What is the maximum power dissipation of SZBZX84C5V6LT1G on FR-5 board?
SZBZX84C5V6LT1G is rated for 250 mW total power dissipation on FR-5 board at 25°C ambient temperature, with a derating factor of 2.0 mW/°C above that temperature. This value is specified in the Maximum Ratings table on page 2 of the official onsemi datasheet.
Does SZBZX84C5V6LT1G have a connected pin 2?
No, pin 2 of SZBZX84C5V6LT1G is internally unconnected (NC), as confirmed in the Pinout diagrams on pages 2 and 6 of the datasheet and explicitly noted in the Electrical Characteristics tables. The device uses a 3-pin SOT-23 package with functional terminals only at pins 1 (anode) and 3 (cathode).
What is the Zener impedance of SZBZX84C5V6LT1G at 5 mA?
The maximum Zener impedance (ZZT) of SZBZX84C5V6LT1G is 40 Ω when measured at IZT = 5 mA and TA = 25°C. This parameter appears in the ELECTRICAL CHARACTERISTICS table on page 3, confirming regulation stiffness critical for low-noise voltage reference designs.
