Product details
Overview
NZ9F3V6T5G from onsemi is a 3.6 V ±5% Zener diode in SOD−923 package, rated for 250 mW steady-state power dissipation at 25°C, with 100 Ω maximum Zener impedance at 5 mA test current and 10 µA reverse leakage at 2.85 V. It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection circuits.
For engineers reviewing the NZ9F3V6T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.42–3.78 V Zener voltage range, AEC−Q101 qualification (SZ-prefix variant), 16 kV HBM ESD rating, low 0.40 mm height, and RoHS-compliant matte tin lead finish.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage at its specified Zener voltage when biased above VR. Its thermal resistance of 500 °C/W and 2.0 mW/°C derating above 25°C define safe operating limits under continuous DC or pulsed conditions.
The SOD−923 package enables high-density PCB placement with 1.00 mm × 0.60 mm footprint and MSL 1 reflow compatibility up to 260°C. Marking "3" identifies the NZ9F3V6T5G variant, with cathode indicated by band on terminal 1 per standard diode polarity convention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.42 V min to 3.78 V max @ IZT = 5 mA - defines regulated output voltage window under nominal test conditions |
| Power Dissipation (PD) | 250 mW @ TA = 25°C - maximum continuous power before thermal derating begins |
| Zener Impedance (ZZT) | ≤100 Ω @ IZT = 5 mA - indicates voltage stability under small-signal load variations |
| Reverse Leakage (IR) | ≤10 µA @ VR = 2.85 V - ensures minimal quiescent current in standby or undervoltage states |
| ESD Rating | Class 3 (>16 kV) HBM - supports robust handling in automated assembly and end-user environments |
| Package | SOD−923 (Case 514AB) - 1.00 mm × 0.60 mm × 0.40 mm footprint ideal for ultra-compact layouts |
| Temperature Coefficient | −3.5 mV/°C - quantifies Zener voltage drift over operating temperature range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C3V6LT1G | Same 3.6 V nominal Zener, but SOD-523 package (smaller: 1.2 × 0.8 mm vs 1.0 × 0.6 mm); 350 mW PD; higher ZZK (200 Ω) | Higher power handling suits intermittent surge suppression; smaller pad layout may require redesign | Select when higher pulse energy absorption is needed and board area allows SOD-523 footprint |
| MMSZ4685T1G | 3.6 V nominal, SOD-123 package (larger: 2.7 × 1.4 mm); 500 mW PD; 100 Ω ZZT; no AEC-Q101 qualification | Higher thermal mass supports sustained regulation; lacks automotive qualification and low-height profile | Select for cost-sensitive industrial applications where board space and qualification are secondary |
Compared with NZ9F3V6T5G, BZX584C3V6LT1G offers greater surge capability in a slightly larger footprint, while MMSZ4685T1G delivers higher continuous power in a legacy package-neither is pin-compatible, requiring layout revision for substitution.

FAQ
What is the Zener voltage tolerance of NZ9F3V6T5G?
The NZ9F3V6T5G has a Zener voltage range of 3.42 V to 3.78 V at 5 mA test current, corresponding to a ±5% tolerance around the nominal 3.6 V rating. This tolerance is guaranteed across production lots and verified per the onsemi datasheet Electrical Characteristics table. The NZ9F3V6T5G maintains this specification under standard test conditions at 25°C ambient temperature.
Is NZ9F3V6T5G suitable for automotive applications?
Yes - the SZ-prefix variant (e.g., SZNZ9F3V6T5G) is AEC−Q101 qualified and PPAP capable, making it suitable for automotive applications. The NZ9F3V6T5G itself is the commercial-grade version; both share identical electrical and mechanical specifications except for qualification documentation and traceability controls. For automotive use, specify the SZ prefix to ensure compliance with automotive quality systems.
What is the maximum operating temperature for NZ9F3V6T5G?
The NZ9F3V6T5G has a junction and storage temperature range of −65°C to +150°C. Its thermal resistance is 500°C/W, and power must be derated linearly above 25°C at 2.0 mW/°C. At 100°C ambient, the maximum allowable power dissipation drops to 100 mW. This thermal behavior is fully characterized in the onsemi datasheet Maximum Ratings table and Figure 1.
Does NZ9F3V6T5G have RoHS and halogen-free compliance?
Yes - the NZ9F3V6T5G is Pb−Free, Halogen Free/BFR Free, and fully RoHS compliant per Directive 2011/65/EU. Its matte tin lead finish and thermosetting epoxy mold compound meet UL 94 V−0 flammability requirements. Compliance documentation, including material declarations and test reports, is available through onsemi's product environmental page for NZ9F3V6T5G.
How is the cathode identified on NZ9F3V6T5G?
The cathode of NZ9F3V6T5G is marked by a visible band on Terminal 1 of the SOD−923 package, consistent with industry-standard diode polarity marking. In top-view orientation with the marking side up and the band to the left, Terminal 1 (cathode) is on the left and Terminal 2 (anode) is on the right. This marking aligns with the pin diagram in the onsemi datasheet and is confirmed in the Device Marking Information section for NZ9F3V6T5G.
