Product details
Overview
BZX84C3V3S-7-F from Diodes Incorporated is a 3.3 V, 200 mW surface-mount Zener diode in SOT-363 package, with nominal zener voltage 3.3 V (min 3.1 V, max 3.5 V at 5 mA), zener impedance ≤95 Ω at 5 mA, and reverse current ≤5 µA at 1 V, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84C3V3S-7-F datasheet, BZX84C3V3S-7-F pinout, BZX84C3V3S-7-F application, or BZX84C3V3S-7-F equivalent, key selection criteria include zener voltage tolerance (±0.2 V), low leakage (5 µA @ 1 V), thermal resistance (625 °C/W), RoHS-compliant matte tin plating, and SOT-363 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual-diode Zener operates in reverse breakdown to maintain stable voltage across load variations, with test current fixed at 5 mA per diode and specified zener impedance measured at 1 kHz. Its planar die construction ensures consistent voltage regulation under transient conditions.
The device features ultra-small SOT-363 packaging with six terminals (two anodes, two cathodes, two NC), enabling dual-channel voltage clamping or reference in one footprint. Polarity is defined by top-view schematic: C1/A1/A2/C2/NC/NC, with cathodes marked on package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | Single 3.3 V Zener, SOT-23 package, 200 mW, 100 Ω zener impedance | Single-channel only; lacks dual-diode integration | Select when board space allows separate placement and dual-channel functionality is unnecessary |
| BZX84C3V3LT1G | Single 3.3 V Zener, SOT-23 package, 350 mW, 95 Ω zener impedance, higher power rating | Higher power dissipation but no dual configuration | Choose for higher-current regulation where thermal margin is critical and dual channels are not required |
Compared with BZX84C3V3S-7-F, MMBZ5226BS-7-F offers identical voltage spec but sacrifices dual-channel integration, while BZX84C3V3LT1G provides greater thermal headroom at the cost of losing independent dual-cathode clamping capability.

FAQ
What is the maximum reverse current for BZX84C3V3S-7-F at 1 V?
The maximum reverse current is 5.0 µA at VR = 1 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains valid up to +125 °C with minor degradation; actual leakage increases to ~15 µA at +150 °C per typical characterization curves in DS30108 Rev. 17.
Is BZX84C3V3S-7-F compatible with lead-free reflow soldering profiles?
Yes - it is RoHS-compliant with matte tin plating over Alloy 42 leadframe and rated for standard JEDEC J-STD-020D Level 1 moisture sensitivity. The device withstands peak reflow temperatures up to 260 °C for 10 seconds without degradation, per Diodes Incorporated's packaging specifications.
How does the dual-diode configuration benefit circuit design?
The dual configuration allows independent regulation or clamping on two nodes using one footprint - for example, stabilizing both AVDD and DVDD rails in mixed-signal ICs or implementing redundant overvoltage protection paths. Pin separation (C1/A1 and C2/A2) prevents interaction between channels.
What is the temperature coefficient of the zener voltage?
The temperature coefficient is −3.5 mV/°C minimum and 0 mV/°C maximum at IZT = 5 mA, indicating a negative or near-zero drift over temperature. This behavior is typical for low-voltage Zeners (<5 V) and supports stable reference performance in ambient-temperature-stable applications.
