Product details
Overview
BZT52C8V2-13-F from Diodes Incorporated is a surface-mount 8.2 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 15 Ω typical Zener impedance at 5 mA test current and ±5% voltage tolerance. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZT52C8V2-13-F datasheet, BZT52C8V2-13-F pinout, BZT52C8V2-13-F application, or BZT52C8V2-13-F equivalent, this part supports stable voltage regulation in space-constrained PCBs where AEC-Q101 qualification, RoHS compliance, and automated assembly compatibility are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 8.2 V (min 7.7 V, max 8.7 V) at 5 mA test current, exhibiting a positive temperature coefficient of +3.2 mV/°C. Its thermal resistance junction-to-ambient is 338 °C/W on FR-4 with 1-inch copper pad, limiting continuous power handling under elevated ambient temperatures.
The device features planar die construction, matte tin-plated alloy 42 leadframe, and cathode band polarity marking. It is qualified to AEC-Q101 for automotive-grade reliability and conforms to halogen- and antimony-free "Green" specifications (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5231BS-7-F | Same 8.2 V nominal rating but SOT-23 package; 350 mW PD at +25°C; 20 Ω ZZT | Higher thermal resistance due to smaller SOT-23 footprint; less suitable for sustained 370 mW operation | Select when board space is constrained and peak power is <300 mW |
| BZX84-C8V2 | 8.2 V Zener in SOT-23; 350 mW rating; ±5% tolerance; 20 Ω ZZT; no AEC-Q101 qualification | Lacks automotive qualification and halogen-free certification; lower reliability assurance for harsh environments | Select for cost-sensitive commercial designs where AEC-Q101 is not required |
Compared with MMBZ5231BS-7-F and BZX84-C8V2, BZT52C8V2-13-F delivers higher power handling (370 mW), lower dynamic impedance (15 Ω), and full AEC-Q101/halogen-free compliance-making it optimal for automotive and industrial applications demanding robustness and precision.

FAQ
What is the maximum reverse voltage (VR) at which leakage remains below 1 µA?
The datasheet specifies 0.7 µA maximum reverse current at VR = 6.2 V. At VR = 7.0 V, leakage rises to approximately 2.5 µA per typical characteristics curve (Fig. 2). For sub-1 µA operation, limit reverse bias to ≤6.2 V in design.
Can BZT52C8V2-13-F be used in parallel for higher power handling?
No-Zener diodes exhibit manufacturing spread in VZ, causing current hogging in parallel configurations. Even matched units show >±5% tolerance, leading to thermal runaway. Use a single device rated for required power or select a higher-PD alternative like 1N4738A (1 W, DO-41).
Is the SOD123 package compatible with IPC-7351B standard footprints?
Yes-the SOD123 outline dimensions (D = 1.40–1.70 mm, E = 2.55–2.85 mm, He = 3.55–3.85 mm) align with IPC-7351B generic SOD-123 land pattern. Recommended pad layout: X = 0.90 mm, X1 = 4.05 mm, Y = 0.95 mm per Diodes' suggested footprint.
Does the "-13-F" suffix indicate tape-and-reel packaging and RoHS compliance?
Yes: "-13-F" denotes 10,000-unit tape-and-reel packaging (vs. "-7-F" for 3,000 units); "F" confirms fully RoHS-compliant, lead-free, and halogen-free construction per Diodes' green product definition.
