For engineers reviewing the SZNZ9F6V2T5G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SOD-923 mechanical dimensions, and direct automotive-grade alternatives with documented voltage tolerance and impedance differences.
Technical Context
This device operates as a two-terminal voltage reference with sharp reverse breakdown at nominal 6.2 V, specified under 5 mA Zener test current (IZT) and validated across −65 °C to +150 °C junction temperature range. Its 60 Ω dynamic impedance (ZZT) and 0.4 mV/°C temperature coefficient ensure stable regulation under moderate load variation and ambient shifts.
The SZNZ9F6V2T5G features Class 3 HBM ESD rating (>16 kV), Pb-free/halogen-free construction per RoHS, and MSL 1 reflow compatibility up to 260 °C - enabling use in high-density PCBs requiring robust transient immunity and lead-free assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1SMB5919BT3G | 7.5 V nominal, 1.5 W power rating, DO-214AA package (4.5 mm × 3.5 mm) | Higher power handling but 4.5× larger footprint; suited for board-level surge suppression, not space-constrained IC biasing | Select when >250 mW dissipation or higher surge energy absorption is required; not suitable for SOD-923 layout constraints |
| MMSZ5234B-TP | 6.2 V nominal, 500 mW rating, SOD-123 package (3.7 mm × 1.6 mm), 100 Ω ZZT | Larger size and higher impedance reduce regulation accuracy in precision analog circuits | Choose only if SOD-123 is already standardized in design; inferior regulation performance vs. SZNZ9F6V2T5G in compact, low-noise applications |
Compared with 1SMB5919BT3G and MMSZ5234B-TP, the SZNZ9F6V2T5G delivers superior voltage regulation accuracy (±5% vs. ±5% but tighter 60 Ω ZZT), smallest footprint (1.00 mm × 0.60 mm), and automotive qualification - making it optimal for miniaturized, high-reliability systems where board space and thermal stability are critical.

FAQ
What is the Zener voltage tolerance of SZNZ9F6V2T5G?
The SZNZ9F6V2T5G has a guaranteed Zener voltage range of 5.89 V to 6.51 V at 5 mA test current (IZT), representing a ±5% tolerance around the nominal 6.2 V rating. This tolerance is measured at 25 °C ambient and remains stable across its qualified operating temperature range due to its +0.4 mV/°C temperature coefficient. The SZNZ9F6V2T5G datasheet specifies these limits in the Electrical Characteristics table on page 3.
Is SZNZ9F6V2T5G suitable for automotive applications?
Yes, the SZNZ9F6V2T5G is AEC-Q101 qualified and PPAP capable, with the "SZ" prefix explicitly indicating compliance for automotive and other high-reliability applications. It meets stringent stress testing requirements including temperature cycling, humidity bias, and mechanical shock. The SZNZ9F6V2T5G is routinely deployed in cabin controllers, body electronics, and infotainment power rails where long-term stability and failure mode predictability are mandatory.
What is the maximum power dissipation of SZNZ9F6V2T5G at 85 °C ambient?
At 85 °C ambient temperature, the SZNZ9F6V2T5G's maximum power dissipation is derated linearly from 250 mW at 25 °C using the 2.0 mW/°C derating factor. This yields 250 mW − (85 − 25) × 2.0 mW = 130 mW. This value is confirmed by Figure 1 (Steady State Power Derating) in the onsemi datasheet and applies to FR-5 board mounting with minimum pad layout.
Does SZNZ9F6V2T5G have a defined forward voltage specification?
Yes, the SZNZ9F6V2T5G specifies a maximum forward voltage (VF) of 0.9 V at 10 mA forward current (IF), as stated in the Electrical Characteristics table. This parameter is relevant for applications where the device may be forward-biased during startup sequencing or fault conditions, ensuring predictable conduction behavior and avoiding unintended latch-up in adjacent circuitry.
What packaging and marking format does SZNZ9F6V2T5G use?
The SZNZ9F6V2T5G is supplied in SOD-923 package (Case 514AB) with tape-and-reel packaging (8,000 units per reel). Its top-side marking consists of a single alphanumeric code "6", denoting the 6.2 V variant, followed by a date code. The cathode is identified by a polarity band at Pin 1, consistent with the SOD-923 mechanical drawing in the datasheet.
