Product details
Overview
BZX84C8V2 RFG from Taiwan Semiconductor is a surface-mount Zener diode with nominal zener voltage 8.2 V, 300 mW power dissipation, and SOT-23 package; it provides precise low-voltage regulation in DC/DC converters, lighting drivers, and adapter circuits.
For engineers reviewing the BZX84C8V2 RFG datasheet, BZX84C8V2 RFG pinout, BZX84C8V2 RFG application, or BZX84C8V2 RFG equivalent, key selection criteria include zener voltage tolerance (±0.5 V), zener impedance (15 Ω @ 5 mA), leakage current (0.7 µA @ 5.0 V), temperature coefficient (+3.2 mV/°C), and thermal resistance (417 °C/W).
Technical Context
This device operates as a single-die, silicon planar Zener diode optimized for stable voltage reference and low-power regulation at 8.2 V nominal breakdown. It delivers tight voltage tolerance (7.7–8.7 V), low dynamic impedance (15 Ω at 5 mA test current), and controlled positive temperature coefficient (+3.2 mV/°C) to minimize drift across operating temperatures.
Designed for surface-mount assembly with moisture sensitivity level 1 per J-STD-020, the BZX84C8V2 RFG features matte tin-plated leads, halogen-free molding compound (IEC 61249-2-21), and junction temperature range from –65 °C to +150 °C - enabling reliable operation in compact, thermally constrained industrial and consumer power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.2 V nominal, 7.7–8.7 V range at IZT = 5 mA - ensures stable reference within ±6% tolerance under standard bias |
| Power Dissipation (PD) | 300 mW at TA = 25 °C - supports continuous regulation in low-power linear supplies without forced cooling |
| Zener Impedance (ZZT) | 15 Ω at IZT = 5 mA - maintains voltage stability against load transients in feedback networks |
| Leakage Current (IR) | 0.7 µA max at VR = 5.0 V - minimizes quiescent current loss in battery-backed or energy-sensitive circuits |
| Temperature Coefficient | +3.2 mV/°C - enables predictable, low-drift behavior in ambient temperature variations up to +85 °C |
| Junction-to-Ambient RθJA | 417 °C/W - defines thermal derating slope: power must be reduced by ~0.72 mW/°C above 25 °C ambient |
Pinout & Package
Package: SOT-23 - 3-terminal, surface-mount plastic package with 1.3 mm height, 2.9 mm length, and 1.3 mm width; RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower potential side in reverse-biased Zener configuration; carries forward current during transient clamping |
| Cathode (Pin 2) | Zener breakdown terminal | Connected to higher potential side; establishes regulated voltage drop when reverse biased above 8.2 V |
| No-connect / Heat sink (Pin 3) | Collector / Thermal pad (non-functional) | SOT-23 Pin 3 is internally unconnected; serves only mechanical anchoring and minor thermal conduction via PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free construction | Complies with IEC 61249-2-21 - eliminates brominated flame retardants for safer end-of-life processing |
| Moisture sensitivity level 1 | Unlimited floor life at ≤30 °C/60% RH - eliminates baking requirement before reflow soldering |
| Matte tin-plated leads | Solderable per J-STD-002 - ensures consistent wetting and joint reliability with lead-free SAC305 paste |
| Single-die configuration | Monolithic silicon junction - avoids mismatch or drift issues associated with multi-die or stacked assemblies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5233BS-7-F (Diodes Inc.) | 8.2 V nominal, 200 mW PD, 20 Ω ZZT, –65 to +150 °C TJ | Lower power rating requires derating above 70 °C ambient; higher ZZT reduces regulation precision | Preferred where board space matches SOT-23 but volume cost is critical and thermal margin exceeds 15 °C |
| BZX84-C8V2,115 (Nexperia) | 8.2 V nominal, 300 mW PD, 15 Ω ZZT, same SOT-23, AEC-Q200 qualified | Automotive-qualified variant adds vibration/thermal cycling robustness; identical electrical specs | Recommended for automotive body electronics where qualification compliance is mandatory and no layout change is allowed |
Compared with MMBZ5233BS-7-F and BZX84-C8V2,115, the BZX84C8V2 RFG offers identical regulation performance and thermal capability as the Nexperia part but without AEC-Q200 validation, while providing higher power headroom and lower impedance than the Diodes Inc. alternative - making it optimal for industrial and commercial DC/DC and lighting applications requiring cost-effective, high-precision voltage referencing.

FAQ
What is the nominal zener voltage and tolerance of the BZX84C8V2 RFG?
The BZX84C8V2 RFG has a nominal zener voltage of 8.2 V with a guaranteed range of 7.7 V to 8.7 V at test current IZT = 5 mA. This ±0.5 V tolerance ensures predictable regulation in feedback networks and voltage references without external trimming. The BZX84C8V2 RFG achieves this specification under standard pulse testing conditions (300 µs width, 5 ms period) per the Taiwan Semiconductor datasheet.
Does the BZX84C8V2 RFG meet RoHS and halogen-free requirements?
Yes, the BZX84C8V2 RFG is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed by its "G" suffix in the ordering code and explicit statement in the manufacturer's documentation. The "RFG" designation indicates green compound packaging, and the device uses matte tin-plated leads compatible with lead-free soldering processes. The BZX84C8V2 RFG meets both environmental and assembly standards required for modern consumer and industrial electronics.
What is the maximum power dissipation and thermal derating behavior of the BZX84C8V2 RFG?
The BZX84C8V2 RFG has a maximum power dissipation of 300 mW at 25 °C ambient temperature, with a junction-to-ambient thermal resistance of 417 °C/W. Its power rating decreases linearly above 25 °C - approximately 0.72 mW/°C - per the derating curve in the datasheet. This behavior is critical when using the BZX84C8V2 RFG in enclosed or high-ambient environments, where PCB copper area and airflow must be evaluated to avoid exceeding 150 °C maximum junction temperature.
How does the temperature coefficient of the BZX84C8V2 RFG affect voltage stability?
The BZX84C8V2 RFG exhibits a positive temperature coefficient of +3.2 mV/°C, meaning its zener voltage increases predictably with rising junction temperature. This characteristic enables stable performance across industrial temperature ranges (–40 to +85 °C ambient), especially when used in compensated reference designs. For example, over a 60 °C rise, the BZX84C8V2 RFG shifts by only +192 mV - well within typical system tolerances. This value is measured at IZT = 5 mA and is specified in the electrical characteristics table.
Is the BZX84C8V2 RFG suitable for use in automotive applications?
The BZX84C8V2 RFG is not AEC-Q200 qualified and is intended for industrial and commercial applications only. While it shares identical electrical specifications with automotive-qualified equivalents like Nexperia's BZX84-C8V2,115, the BZX84C8V2 RFG lacks the extended temperature cycling, humidity, and vibration validation required for automotive deployment. Customers requiring automotive-grade reliability should select the qualified alternative and verify full system-level compliance before integration. The BZX84C8V2 RFG remains ideal for non-automotive power regulation tasks.
