Product details
Overview
BZX84C15S-7-F from Diodes Incorporated is a 15 V, 200 mW surface-mount Zener diode in SOT-363 package, specified at 5 mA test current with ±0.6 V tolerance (13.8–15.6 V), 30 Ω dynamic impedance at 5 mA, and 0.1 µA maximum reverse leakage at 10.5 V. It provides precision voltage regulation in low-power biasing and reference circuits.
For engineers reviewing the BZX84C15S-7-F datasheet, BZX84C15S-7-F pinout, BZX84C15S-7-F application, or BZX84C15S-7-F equivalent, key selection criteria include zener voltage tolerance, thermal resistance (625 °C/W), reverse leakage at VR, temperature coefficient (+9.2 to +13.0 mV/°C), and SOT-363 footprint compatibility with high-density PCB layouts.
Technical Context
This dual-anode, common-cathode Zener diode uses planar die construction for stable breakdown characteristics and low noise. Its 200 mW power dissipation is rated at 25 °C ambient and derates linearly above 50 °C per the published curve.
The device exhibits a positive temperature coefficient (+9.2 to +13.0 mV/°C) at 5 mA, enabling predictable drift compensation in reference designs. Reverse leakage remains ≤0.1 µA up to 10.5 V, supporting low-current standby regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V nominal, 13.8–15.6 V range at IZT = 5 mA - defines regulation setpoint with ±4% tolerance |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - limits continuous DC or pulsed regulation current in compact layouts |
| Zener Impedance (ZZT) | 30 Ω max at IZT = 5 mA - determines output voltage stability under load variation |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 10.5 V - ensures minimal quiescent current in battery-backed references |
| Temp Coefficient (αVZ) | +9.2 to +13.0 mV/°C at IZT = 5 mA - enables thermal drift modeling in precision analog circuits |
| Package | SOT-363 - 6-pin ultra-small outline with dual Zener configuration and common cathode |
| Thermal Resistance (RθJA) | 625 °C/W on FR4 board - dictates junction temperature rise under full power in standard layout |
Pinout & Package
SOT-363 package: 2.2 mm × 1.3 mm × 0.9 mm body, molded plastic UL 94V-0, lead-free matte tin plating, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Unbonded pad - must be left floating or grounded per layout guidelines; no internal connection |
| 2 (C1) | Cathode 1 | Common cathode terminal for first Zener element - connects to regulated rail return |
| 3 (A1) | Anode 1 | Anode of first Zener - ties to input supply or bias node for 15 V regulation |
| 4 (A2) | Anode 2 | Anode of second Zener - enables dual independent 15 V references or series/parallel configurations |
| 5 (C2) | Cathode 2 | Shared cathode with Pin 2 - confirms dual-anode, common-cathode topology |
| 6 (NC) | No Connect | Unbonded pad - electrically isolated; no routing required |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Ensures repeatable breakdown voltage and low parameter drift over time and temperature |
| Ultra-small SOT-363 footprint | Supports >2× higher component density than SOT-23 in space-constrained portable and IoT PCBs |
| Lead-free / RoHS-compliant | Meets global environmental compliance without requiring special soldering profiles or exemptions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4685-7-F | Same 15 V nominal, but SOD-123 package; 500 mW PD; 30 Ω ZZT; -3.5 to 0 mV/°C TC | Higher power handling, single-element, negative TC - better for temp-stable shunt regulators | Select when higher power margin or single-Zener topology is required |
| BZX84C15LT1G | SOT-23 package; identical electrical specs; same 200 mW rating and ±4% VZ tolerance | Single-anode, single-cathode; incompatible pinout; no dual-Zener capability | Select only if dual-Zener function is unnecessary and SOT-23 footprint is preferred |
Compared with MMSZ4685-7-F and BZX84C15LT1G, BZX84C15S-7-F uniquely supports dual 15 V Zener elements in one SOT-363 footprint - enabling compact redundancy, differential referencing, or dual-rail biasing not possible with single-diode alternatives.

FAQ
What is the maximum reverse voltage (VR) at which leakage stays ≤0.1 µA?
The BZX84C15S-7-F guarantees ≤0.1 µA reverse leakage at VR = 10.5 V, as specified in the Electrical Characteristics table. At 15 V, leakage rises significantly due to onset of breakdown; operation above 10.5 V in non-regulating mode is not recommended for low-leakage applications.
Can Pins 1 and 6 be used as thermal pads or ground connections?
No - Pins 1 and 6 are explicitly marked "NC" (No Connect) in the datasheet and confirmed as unconnected die pads. They must remain electrically floating or tied to ground only for mechanical stability; no current path or thermal conduction benefit is provided through these terminals.
How does the +9.2 to +13.0 mV/°C temperature coefficient affect circuit design?
This positive coefficient means VZ increases ~11 mV per °C rise at 5 mA. Designers must account for this drift in precision references - e.g., by calibrating at operating temperature or pairing with a negative-TC component to achieve net zero drift in compensated circuits.
Is the SOT-363 footprint compatible with standard reflow profiles for lead-free solder?
Yes - the device uses matte tin finish over Alloy 42 leadframe and meets J-STD-020D Level 1 moisture sensitivity. It is qualified for standard Pb-free reflow profiles (peak 260 °C, 60 sec max), with no pre-bake required, simplifying high-volume manufacturing.
