Product details
Overview
BZX84C36-7 from Diodes Incorporated is a 36V, 2mA nominal Zener diode in SOT23 package with 350mW power dissipation, ±5.6% voltage tolerance (34.0–38.0V), 90Ω dynamic impedance at 2mA, and -3.5mV/°C temperature coefficient-used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84C36-7 datasheet, BZX84C36-7 pinout, BZX84C36-7 application, or BZX84C36-7 equivalent, key selection criteria include Zener voltage accuracy at 2mA test current, thermal stability across -65°C to +150°C, SOT23 footprint compatibility, and compliance with AEC-Q101 for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 36V at 2mA test current (IZT), exhibiting a tight 34.0–38.0V range and low 90Ω impedance at IZT. Its negative temperature coefficient (-3.5mV/°C) ensures predictable drift under thermal variation.
Designed for surface-mount assembly on FR-4 PCBs, it delivers 350mW power dissipation when terminals are held at ambient temperature and maintains stable regulation down to 0.1µA reverse leakage (IR) at 30.4V (VR), supporting low-quiescent-current biasing and sensing applications.

| Zener Impedance (ZZT) | 90Ω at 2mA-ensures minimal output voltage shift under load transients |
| Reverse Leakage (IR) | 0.1µA max at 30.4V-enables high-impedance bias networks without significant error current |
| Temperature Coefficient | -3.5mV/°C-predictable downward drift improves stability in temperature-compensated references |
| Package | SOT23-standard 3-pin surface-mount footprint compatible with automated pick-and-place and reflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245B-7-F | 36V nominal, 350mW, but 100Ω ZZT at 20mA (not 2mA); ±5% tolerance | Higher test current shifts operating point-less suitable for micro-power biasing | Select when higher IZT is acceptable and tighter ZZT at 20mA matters more than low-current stability |
| BZX84-C36,115 | Same electrical specs, but SOT23-3 package with different marking and packaging (10k/reel vs. 3k/reel) | No functional difference-only logistics and traceability distinction | Prefer for volume procurement where tape-and-reel quantity aligns with production line feeders |
Compared with MMBZ5245B-7-F and BZX84-C36,115, the BZX84C36-7 offers optimal balance of low-current Zener stability (2mA IZT), industry-standard SOT23 pinout, and AEC-Q101 qualification-making it preferred for automotive and precision analog designs where test-current alignment and qualification matter.

FAQ
What is the maximum reverse voltage (VR) at which BZX84C36-7 guarantees ≤0.1µA leakage?
The datasheet specifies 30.4V as the maximum reverse voltage (VR) at which reverse current (IR) is guaranteed ≤0.1µA. This value is derived from the 85% derating of the nominal 36V Zener voltage and is critical for designing high-impedance bias networks where leakage-induced error must be minimized.
Does BZX84C36-7 have a defined forward voltage (VF), and what is its typical value?
Yes-BZX84C36-7 has a specified forward voltage of 0.9V at 10mA forward current (IF). This parameter is relevant for polarity verification during board-level testing and for applications where the device may experience brief forward conduction during power-up sequencing or fault conditions.
How does the -3.5mV/°C temperature coefficient affect circuit performance over temperature?
The negative temperature coefficient means the Zener voltage decreases by 3.5mV per degree Celsius rise. Over a 100°C range (e.g., -40°C to +60°C), this results in ~350mV total drift-requiring compensation in precision references but offering predictable behavior for temperature-sensing or compensation circuits.
Is the third pin (Pin 3) of the SOT23 package electrically connected internally?
No-Pin 3 is a non-functional lead with no internal connection. It serves only as mechanical reinforcement within the SOT23 mold structure and must not be used as a signal or ground path in PCB layout or schematic symbol definition.
