Product details
Overview
BZX84C3V6Q-13-F from Diodes Incorporated is a 3.6 V, 5 mA nominal Zener voltage regulator diode in SOT23 package, rated for 350 mW power dissipation at ambient temperature, with 90 Ω maximum Zener impedance at test current and -3.5 mV/°C temperature coefficient - used for precision voltage reference and overvoltage protection in low-power sensor signal conditioning circuits.
For engineers reviewing the BZX84C3V6Q-13-F datasheet, BZX84C3V6Q-13-F pinout, BZX84C3V6Q-13-F application, or BZX84C3V6Q-13-F equivalent, this page delivers verified electrical parameters, automotive-grade qualification status, thermal derating behavior, SOT23 terminal mapping, and direct-fit alternatives for voltage regulation design-in.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. It features planar die construction and is qualified to AEC-Q101 for automotive reliability, with a nominal Zener voltage of 3.6 V at 5 mA test current and a tight tolerance (±0.2 V) between 3.4 V and 3.8 V.
Thermal resistance is 357 °C/W when terminals are held at ambient temperature, enabling predictable power derating above +25°C. Its low 0.9 V forward voltage at 10 mA supports bidirectional clamping configurations, and its -3.5 mV/°C temperature coefficient ensures predictable drift in temperature-sensitive references.

FAQ
What is the maximum reverse voltage before breakdown for BZX84C3V6Q-13-F?
The nominal Zener voltage is 3.6 V at 5 mA test current, with a guaranteed range of 3.4 V to 3.8 V. Breakdown begins gradually below this point; the diode reaches full regulation within ±5 % of nominal voltage at currents ≥1 mA. No hard "maximum reverse voltage" is specified - instead, the device regulates continuously above ~2.5 V in reverse bias.
Can BZX84C3V6Q-13-F be used in forward bias as a standard diode?
Yes - it exhibits 0.9 V forward voltage at 10 mA, matching typical silicon diode behavior. Its planar construction supports reliable forward conduction, making it usable in dual-role circuits such as bidirectional ESD clamps or polarity-protection rectifiers alongside Zener regulation.
How does the -3.5 mV/°C temperature coefficient affect circuit performance?
This coefficient means the Zener voltage decreases by 3.5 mV per °C rise in junction temperature. Over a -40°C to +125°C range, total drift is approximately ±58 mV - a 1.6 % shift relative to 3.6 V. Designers must include this in voltage reference error budgets, especially in unheatsinked SOT23 layouts.
Is the third pin (Pin 3) of the SOT23 package electrically connected?
No - Pin 3 is an internal die attach pad with no electrical connection to the semiconductor die. It is thermally conductive but electrically isolated. PCB layout must treat it as a non-signal thermal pad; connecting it to ground or other nets may cause short circuits or parametric shifts.
