Product details
Overview
BZX584C16-V-G-08 from Vishay Semiconductors is a surface-mount silicon Zener diode in the SOD-523 package, rated for 16 V nominal Zener voltage (±5 % tolerance) at 5 mA test current, with 200 mW power dissipation and dynamic resistance ≤40 Ω at IZT. It provides precision voltage regulation in space-constrained analog and power-supply feedback circuits.
For engineers reviewing the BZX584C16-V-G-08 datasheet, BZX584C16-V-G-08 pinout, BZX584C16-V-G-08 application, or BZX584C16-V-G-08 equivalent, key selection criteria include Zener voltage accuracy, low leakage (<50 nA at 12.8 V), thermal resistance (680 K/W), compact SOD-523 footprint, and MSL Level 1 solderability - all critical for high-density portable and battery-powered designs.
Technical Context
The BZX584C16-V-G-08 operates as a single-element, unidirectional Zener diode optimized for stable voltage reference and overvoltage clamping. Its 16 V nominal breakdown voltage is specified at 5 mA with ±5 % tolerance, and it exhibits a positive temperature coefficient of +8 to +9.5 × 10−4/°C, ensuring predictable drift across industrial temperature ranges.
Designed for low-power regulation, it delivers 10 Ω typical dynamic impedance at 5 mA and maintains reverse leakage ≤50 nA at 12.8 V (80 % of VZ). The device is qualified per J-STD-020 MSL Level 1 and supports reflow up to 260 °C for 10 s at terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3–17.1 V at 5 mA - ensures tight regulation window for 16 V rail monitoring and feedback |
| Power Dissipation (Ptot) | 200 mW on fiberglass PCB - defines maximum continuous power handling without derating |
| Dynamic Resistance (ZZ) | ≤40 Ω at 5 mA - minimizes output voltage variation under load transients |

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 | 16 V nominal, ±5 %, but in SOT-323 package (2.2 × 1.35 mm); higher RthJA (500 K/W), higher leakage (1 μA at 12.8 V) | Larger footprint limits use in ultra-dense layouts; higher leakage reduces battery life in always-on metering | Select when board space allows larger package and higher leakage is acceptable |
| BZX384-C16,115 | 16 V nominal, ±5 %, in SOD-323 (1.7 × 1.25 mm); 300 mW Ptot, but MSL Level 1 not guaranteed | Higher power rating suits higher-current regulation; larger width may conflict with fine-pitch routing | Prefer where >200 mW dissipation is required and moisture sensitivity control is less critical |
Compared with MMBZ5245BS-7-F and BZX384-C16,115, the BZX584C16-V-G-08 offers the smallest footprint (SOD-523), lowest leakage, and guaranteed MSL Level 1 - making it optimal for miniaturized, low-power, high-reliability applications where board area and standby current are constrained.

FAQ
What is the Zener voltage tolerance of the BZX584C16-V-G-08?
The BZX584C16-V-G-08 has a Zener voltage tolerance of ±5 %, meaning its nominal 16 V breakdown occurs between 15.3 V and 17.1 V when tested at 5 mA. This tolerance is guaranteed across the full operating temperature range and is verified per Vishay's production test flow, ensuring consistent performance in voltage-reference and clamping applications.
Does the BZX584C16-V-G-08 require moisture baking before reflow soldering?
No, the BZX584C16-V-G-08 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require moisture baking prior to reflow. Its UL 94 V-0 molding compound and hermetic sealing allow direct placement and standard 260 °C/10 s reflow without preconditioning - reducing manufacturing overhead and process risk.
What is the maximum reverse leakage current for the BZX584C16-V-G-08 at 12.8 V?
The BZX584C16-V-G-08 guarantees reverse leakage current ≤50 nA at 12.8 V (80 % of nominal VZ). This ultra-low leakage is critical for battery-powered systems where standby current must remain below 100 nA, and it is measured and binned during final test to ensure compliance across all production units.
Can the BZX584C16-V-G-08 be used in place of a 1N4744A in a 16 V regulator?
No - the BZX584C16-V-G-08 is not a drop-in replacement for the 1N4744A. While both regulate near 16 V, the 1N4744A is a 1 W through-hole device in DO-41 package with different thermal and electrical characteristics. The BZX584C16-V-G-08 is a 200 mW SOD-523 surface-mount part; substituting it requires layout revision, power derating, and validation of dynamic impedance and temperature drift in the target circuit.
What is the temperature coefficient of the BZX584C16-V-G-08, and how does it affect long-term stability?
The BZX584C16-V-G-08 has a temperature coefficient of +8 to +9.5 × 10−4/°C, indicating its Zener voltage increases by ~0.08–0.095 V per 100 °C rise. This positive drift is well-characterized and repeatable, allowing accurate compensation in precision references - for example, a +50 °C shift yields +4 to +4.75 mV change, which remains within 0.03 % of nominal VZ.
