Product details
Overview
BZX84C16S-7-F from Diodes Incorporated is a dual 200 mW surface-mount Zener diode with nominal zener voltage 16 V, ±6.25% tolerance (15.3–17.1 V), 40 Ω maximum zener impedance at 5 mA test current, and operates across –65 °C to +150 °C. It provides precision voltage regulation in compact SOT-363 package for low-power biasing and reference applications.
For engineers reviewing the BZX84C16S-7-F datasheet, BZX84C16S-7-F pinout, BZX84C16S-7-F application, or BZX84C16S-7-F equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at IZT, reverse leakage at rated voltage, thermal resistance (625 °C/W), and RoHS-compliant green packaging.
Technical Context
This dual-element Zener diode integrates two independent 16 V zener junctions in a single SOT-363 package, sharing no internal connection-each anode-cathode pair functions as a discrete regulator. Its planar die construction ensures stable breakdown characteristics and low temperature coefficient (+10.4 to +14.0 mV/°C).
Designed for low-current voltage reference and overvoltage clamping, it delivers specified performance at IZT = 5 mA with VZ = 16 V, IZK = 1.0 mA, and IR ≤ 0.1 µA at VR = 11.2 V - meeting tight regulation needs in space-constrained analog signal chains and power supply feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V nominal, 15.3–17.1 V range at IZT = 5 mA - defines stable regulation point for feedback or reference circuits |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - limits continuous current to ~12.5 mA at 16 V without heatsinking |
| Zener Impedance (ZZT) | 40 Ω max at IZT = 5 mA - determines output voltage variation under load transients |
| Reverse Leakage (IR) | ≤ 0.1 µA at VR = 11.2 V - ensures minimal error current in high-impedance reference nodes |
| Thermal Resistance (RθJA) | 625 °C/W on FR4 board - requires derating above 25 °C ambient; full power only at TA ≤ 25 °C |
| Temp. Coefficient (αVZ) | +10.4 to +14.0 mV/°C at IZT = 5 mA - quantifies drift direction and magnitude per degree Celsius |
| Package | SOT-363 - 6-pin ultra-small outline with dual isolated diode elements, footprint 2.2 × 1.35 mm |
Pinout & Package
SOT-363 package houses two independent Zener diodes. Pin assignment follows standard dual-diode configuration: Pins 1 & 2 (C1, A1), Pins 4 & 5 (C2, A2); Pins 3 & 6 are NC (no connection). Molded plastic case meets UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (C1) | Cathode of Diode 1 | Connected to regulated output node; reverse-biased during zener operation |
| Pin 2 (A1) | Anode of Diode 1 | Typically grounded or tied to lower potential; completes bias path for Diode 1 |
| Pin 3 (NC) | No Connection | Not internally bonded; must remain unconnected in PCB layout |
| Pin 4 (C2) | Cathode of Diode 2 | Independent cathode terminal enabling dual-channel regulation or redundancy |
| Pin 5 (A2) | Anode of Diode 2 | Separate anode node allows independent biasing of second zener element |
| Pin 6 (NC) | No Connection | Not internally bonded; electrically floating and unused |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Zener elements | Enables two separate 16 V references or clamps in one footprint - reduces board area vs. discrete solutions |
| 200 mW total dissipation | Supports up to ~12.5 mA regulation current at 16 V without external heatsink on standard FR4 |
| Lead-free / RoHS-compliant | Matte tin-plated terminals meet global environmental compliance requirements for commercial and industrial use |
| Ultra-small SOT-363 package | 2.2 mm × 1.35 mm footprint saves >60% board space versus SO-323 or SOT-23 dual variants |
| Low leakage at 11.2 V | IR ≤ 0.1 µA ensures negligible loading on high-impedance sensor or op-amp reference inputs |

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 | Single 16 V Zener, SOT-363, 200 mW, 30 Ω ZZT, 0.1 µA IR at 11 V | Single-element only; lacks dual-diode integration | Select when only one 16 V reference is needed and board space permits duplication for redundancy |
| BZX84C16LT1G | Single 16 V Zener, SOT-23, 350 mW, 40 Ω ZZT, 0.1 µA IR at 11.2 V | Higher power rating but larger footprint; not dual-element | Choose for higher power margin where SOT-23 is already standardized and dual functionality is unnecessary |
Compared with MMBZ5245BS-7-F and BZX84C16LT1G, BZX84C16S-7-F uniquely delivers two independent 16 V Zeners in one SOT-363 - reducing component count and inter-device mismatch in dual-reference or redundant-clamp designs, while maintaining identical electrical specs per element.

FAQ
What is the maximum continuous zener current for BZX84C16S-7-F at 25 °C ambient?
At TA = 25 °C, the device supports up to 12.5 mA continuous current (200 mW ÷ 16 V), assuming no additional PCB copper area. Derating begins immediately above 25 °C per the 625 °C/W RθJA curve - at 50 °C ambient, max current drops to ~8.3 mA.
How are the two Zener diodes arranged inside the SOT-363 package?
The SOT-363 contains two fully isolated Zener diodes: Diode 1 uses Pins 1 (C1) and 2 (A1); Diode 2 uses Pins 4 (C2) and 5 (A2). Pins 3 and 6 are unconnected. No internal bonding links the elements - each operates independently with identical 16 V characteristics.
Does BZX84C16S-7-F meet AEC-Q200 stress testing requirements for automotive use?
No - BZX84C16S-7-F is not AEC-Q200 qualified. While it operates across –65 °C to +150 °C and is used in automotive body electronics, Diodes Incorporated does not list this part in its AEC-Q200-certified portfolio. For qualified alternatives, consult the BZX84C16Q series.
Can BZX84C16S-7-F be used in place of a single 16 V Zener like BZX84C16LT1G?
Yes - either diode element (Pins 1–2 or Pins 4–5) matches BZX84C16LT1G's electrical specs (16 V VZ, 40 Ω ZZT, 0.1 µA IR). However, the SOT-363 footprint differs from SOT-23, requiring PCB redesign. The dual functionality remains unused unless both elements are leveraged.
