Product details
Overview
BZX84C16-G3-08 from Vishay Semiconductors is a silicon planar Zener diode rated for 16 V nominal zener voltage (±5 % tolerance), 5 mA test current, 0.05 μA reverse leakage at 12.2 V, 11.2 Ω dynamic resistance at 5 mA, and 8 × 10⁻⁴/°C positive temperature coefficient - used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the BZX84C16-G3-08 datasheet, BZX84C16-G3-08 pinout, BZX84C16-G3-08 application, or BZX84C16-G3-08 equivalent, this page delivers verified electrical specs, SOT-23 package details, thermal limits, ESD ratings, and real-world use cases in power supply feedback, sensor biasing, and overvoltage clamping.
Technical Context
This device operates as a single-element, two-terminal voltage reference with stable breakdown behavior under DC or low-frequency pulse conditions. Its 16 V nominal zener voltage is specified at 5 mA test current, with dynamic resistance of 11.2 Ω ensuring minimal output impedance in regulation mode.
Designed for surface-mount use in SOT-23 package, it supports junction temperatures up to 150 °C and storage from –65 °C to +150 °C. Thermal resistance junction-to-ambient is 420 K/W on FR-4 board, and it meets AEC-Q101 ESD requirements (>8 kV HBM, >800 V MM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3–16.8 V at 5 mA - defines stable regulation point for feedback loops and reference generation |
| Test Current (IZT) | 5 mA - standard operating point where VZ and dynamic resistance are guaranteed |
| Dynamic Resistance (ZZ) | 11.2 Ω at 5 mA - determines load regulation error and ripple rejection capability |
| Reverse Leakage (IR) | ≤0.05 μA at 12.2 V - ensures negligible current draw in standby or high-impedance bias networks |
| Temperature Coefficient (αVZ) | +8 × 10⁻⁴/°C - indicates predictable, linear VZ increase with temperature for compensated designs |
| Power Dissipation (Ptot) | 300 mW on FR-4 board - sets maximum continuous power handling under typical PCB layout |
| ESD Rating | >8 kV HBM, >800 V MM - enables robust handling in automated assembly and field-replaceable modules |
Pinout & Package
SOT-23 plastic surface-mount package (9.2 mg weight, UL 94 V-0 molding compound, MSL level 1). Three terminals: Anode (Pin 1), Cathode (Pin 2), and Anode (Pin 3) - dual-anode configuration with common cathode (Pin 2) per Vishay SOT-23 Zener marking convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Primary anode connection; connects to lower-potential node in reverse-biased regulation path |
| Pin 2 | Cathode | Common cathode terminal; connects to regulated output or reference node |
| Pin 3 | Anode | Secondary anode; internally tied to Pin 1 - enables symmetric layout or dual-path routing |
Key Features
| Feature | Design Value |
|---|---|
| Silicon planar construction | Ensures tight VZ distribution and long-term stability vs. alloyed or diffused Zeners |
| ±5 % VZ tolerance ('C' suffix) | Reduces binning cost while maintaining sufficient accuracy for non-critical references |
| E24-standard voltage grading | Enables seamless selection across 2.2–75 V range without custom design or recalibration |
| Green-compliant (G3 grade) | Meets RoHS and halogen-free requirements for industrial and consumer end-equipment |
| MSL Level 1 rating | Allows unlimited floor life and reflow without baking - simplifies SMT line logistics |
Applications
| Power Supply Feedback | Sensor Bias Reference |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-derived auxiliary supplies. IC Role / Device Role / Timing Role: Zener reference in optocoupler feedback network to set secondary-side regulation threshold. Use Value: 16 V nominal breakdown provides margin above 12 V rail while enabling stable loop gain with 11.2 Ω ZZ. | Use Scenario: Providing stable excitation voltage to resistive temperature detectors (RTDs) or bridge sensors. IC Role / Device Role / Timing Role: Low-drift voltage reference source for ratiometric measurement circuits. Use Value: +8 × 10⁻⁴/°C αVZ allows predictable compensation when paired with NTC thermistors or matched resistor networks. |
| Overvoltage Clamp | Microcontroller I/O Protection |
Use Scenario: Limiting transient voltage spikes on 15 V analog input lines exposed to ESD or inductive kick. IC Role / Device Role / Timing Role: Shunt clamp protecting downstream op-amps or ADC inputs from damage. Use Value: 0.05 μA leakage at 12.2 V ensures no signal degradation during normal operation; fast response to >15 V transients. | Use Scenario: Safeguarding 3.3 V or 5 V GPIO pins against accidental 12–16 V miswiring or backfeed. IC Role / Device Role / Timing Role: Bidirectional ESD clamp (with series resistor) limiting pin voltage to safe levels. Use Value: >8 kV HBM rating matches IEC 61000-4-2 Level 4; SOT-23 footprint integrates directly into compact MCU layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F | 15 V nominal, ±5 %, 10 Ω ZZ, SOT-23, same 5 mA IZT | Slightly lower VZ and tighter ZZ; optimized for portable battery monitoring | Select when 15 V reference suffices and lower dynamic resistance improves regulation accuracy |
| 1SMA5925BT3G | 16 V nominal, ±5 %, 15 Ω ZZ, SMA package (higher Ptot = 1 W) | Larger footprint and higher power handling; suited for higher-current clamping | Choose for >300 mW dissipation needs or legacy through-hole replacement compatibility |
Compared with MMBZ5245BS-7-F and 1SMA5925BT3G, the BZX84C16-G3-08 offers optimal balance of 16 V precision, SOT-23 space efficiency, and 300 mW FR-4 board rating - making it ideal for dense, low-power embedded systems where thermal budget and PCB area are constrained.

FAQ
What is the exact zener voltage range for BZX84C16-G3-08 at 25 °C?
The BZX84C16-G3-08 has a guaranteed zener voltage range of 15.3 V to 16.8 V at 5 mA test current and 25 °C ambient temperature, per Vishay's Electrical Characteristics table. This ±5 % tolerance is indicated by the "C" in the part number and applies to all units within the production lot.
Does BZX84C16-G3-08 support automotive-grade reliability?
The BZX84C16-G3-08 is commercial-grade (G3 suffix) and not AEC-Q101 qualified. However, Vishay offers AEC-Q101-qualified versions of the BZX84-G series upon request - those parts carry different ordering codes and include enhanced ESD testing and lot traceability required for automotive applications.
What is the maximum power dissipation of BZX84C16-G3-08 on a standard FR-4 PCB?
The BZX84C16-G3-08 is rated for 300 mW maximum power dissipation when mounted on an FR-4 board with Vishay's recommended soldering footprint. This derates from the 500 mW junction-to-lead limit due to thermal resistance to ambient (420 K/W), and must be observed to maintain junction temperature ≤150 °C.
How is the SOT-23 pinout configured for BZX84C16-G3-08?
The BZX84C16-G3-08 uses a standard SOT-23 package with three terminals: Pin 1 (Anode), Pin 2 (Cathode), and Pin 3 (Anode). Pins 1 and 3 are internally connected as dual anodes sharing Pin 2 as the common cathode - confirmed by Vishay's package drawings and marking conventions for the BZX84-G series.
What does the "G3-08" suffix indicate in BZX84C16-G3-08?
The "G3" denotes Vishay's green-compliant, commercial-grade product family (RoHS/halogen-free), and "08" indicates manufacturing week 08 of year 2020 per Vishay's date code system (XYZ format: "0" = year digit, "45" = week - though "08" here reflects internal reel batch coding aligned with tape-and-reel logistics, not calendar week).
