Product details
Overview
BZX84C16W-7-F from Diodes Incorporated is a 16 V, 200 mW surface-mount Zener diode in SOT-323 package, with nominal zener voltage 16 V (min 15.3 V, max 17.1 V), zener test current 5.0 mA, and max zener impedance 40 Ω at IZT; used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the BZX84C16W-7-F datasheet, BZX84C16W-7-F pinout, BZX84C16W-7-F application, or BZX84C16W-7-F equivalent, key selection criteria include zener voltage tolerance (±3.1%), thermal resistance (625 K/W), reverse leakage (≤0.1 µA at 11.2 V), temperature coefficient (+10.4 to +14.0 mV/°C), and RoHS-compliant green molding compound.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. It exhibits a positive temperature coefficient above ~5 V, enabling predictable drift compensation in reference designs.
Its planar die construction ensures consistent breakdown characteristics and low dynamic impedance (40 Ω at 5 mA), while the SOT-323 package supports high-density PCB layouts with minimal thermal mass and JEDEC-compliant solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V nominal, 15.3–17.1 V range at 5 mA - defines regulated output voltage tolerance |
| Power Dissipation (PD) | 200 mW - limits maximum continuous power handling on FR4 board with recommended pad layout |
| Zener Impedance (ZZT) | 40 Ω at 5 mA - determines regulation stiffness and AC ripple rejection capability |
| Reverse Leakage (IR) | ≤0.1 µA at 11.2 V - ensures minimal quiescent current in standby voltage-reference applications |
| Temp Coefficient (αVZ) | +10.4 to +14.0 mV/°C - enables predictable voltage drift modeling over –65°C to +125°C range |
| Thermal Resistance (RθJA) | 625 K/W - indicates junction-to-ambient heat dissipation limit without heatsinking |
| Package | SOT-323 - ultra-small footprint (2.0 × 1.25 × 0.9 mm) for space-constrained PCBs |
Pinout & Package
Package: SOT-323 - three-terminal surface-mount plastic case with lead-free matte tin plating, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal / cathode reference ground | Connected to circuit ground or lower potential node when used as shunt regulator |
| Cathode (Pin 2) | Zener breakdown terminal / regulated output node | Connected to input supply via series resistor; delivers stable 16 V to load |
| Case / Pin 3 | No internal connection | Electrically isolated; serves mechanical anchoring only - not to be tied to any net |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Ensures tight VZ distribution and repeatable ZZT across production lots |

Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Providing stable 16 V reference for ADC biasing or op-amp feedback networks in battery-powered sensors. IC Role / Device Role / Timing Role: Shunt voltage reference maintaining accuracy within ±3.1% across temperature and load. Use Value: Enables <1% full-scale error in 12-bit data acquisition without trimming, leveraging 40 Ω ZZT and low 0.1 µA leakage. | Use Scenario: Protecting microcontroller GPIO pins from transient surges exceeding 16 V in industrial I/O modules. IC Role / Device Role / Timing Role: Reverse-biased clamping element diverting excess energy to ground before damage threshold. Use Value: Limits peak voltage to ≤17.1 V with fast response (<10 ns), supported by low RθJA for brief pulse handling. |
| Temperature-Compensated Bias | Low-Power Voltage Monitor |
Use Scenario: Generating a temperature-stable bias point in RF amplifier bias networks where drift must stay below 20 mV over –40°C to +85°C. IC Role / Device Role / Timing Role: Zener element paired with NTC thermistor to offset +12.2 mV/°C drift. Use Value: Achieves <±5 mV total drift using known αVZ range (+10.4 to +14.0 mV/°C) for predictable compensation design. | Use Scenario: Detecting brown-out conditions in 16 V rail systems (e.g., automotive body control modules). IC Role / Device Role / Timing Role: Threshold detector feeding comparator input when rail drops below 15.3 V. Use Value: Provides sharp turn-on at defined VZ min, with <0.1 µA leakage preserving battery life in always-on monitoring circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F | 16 V nominal, 225 mW PD, 30 Ω ZZT at 10 mA, SOT-323 | Higher test current (10 mA vs. 5 mA); tighter VZ tolerance (±5%) but higher leakage (≤1 µA at 12 V) | Select for improved regulation stiffness where higher bias current is acceptable |
| 1SMA5925BT3G | 16 V nominal, 1.5 W PD, 10 Ω ZZT at 25 mA, SMA package | Higher power rating and lower impedance, but 3.5× larger footprint and 5× higher thermal mass | Select for surge-tolerant clamping where board space permits larger package |
Compared with MMBZ5245BS-7-F and 1SMA5925BT3G, BZX84C16W-7-F offers optimal balance of ultra-compact size, low leakage, and predictable temperature drift for space- and power-constrained reference designs - not suited for high-current or high-energy transients.

FAQ
What is the maximum reverse voltage (VR) at which leakage remains ≤0.1 µA?
The BZX84C16W-7-F guarantees reverse leakage ≤0.1 µA at VR = 11.2 V, per the Electrical Characteristics table. This value is specified as the voltage at which IR is measured for the 16 V grade, not the absolute maximum rating - the absolute maximum non-breakdown reverse voltage is 11.2 V for leakage compliance, while breakdown begins near 15.3 V.
Can this Zener diode be used in series for higher voltage references?
Yes, multiple BZX84C16W-7-F devices can be stacked in series to achieve higher reference voltages (e.g., two in series yields ~32 V), but total tolerance accumulates (±3.1% per device), and thermal coupling between devices may cause mismatched drift. Individual unit variation and power derating per device must be verified.
Is the SOT-323 package compatible with standard reflow profiles for lead-free assembly?
Yes - the device uses matte tin-plated Alloy 42 leads qualified for Pb-free reflow per J-STD-020D Level 1 moisture sensitivity, with peak temperature tolerance up to 260°C. Recommended profile follows IPC/JEDEC J-STD-020 guidelines for small-outline packages.
Does the "-7-F" suffix indicate tape-and-reel packaging and RoHS compliance?
Yes - the "-7-F" suffix denotes 3000-piece tape-and-reel packaging per Diodes Inc. ordering conventions and confirms lead-free/RoHS compliance, including halogen-free green molding compound and annealed matte tin terminations, as documented in DS30066 Rev. 15-2.
