Product details
Overview
BZX84C36S-7-F from Diodes Incorporated is a dual 200mW surface-mount Zener diode with nominal zener voltage 36V (34–38V range), 2mA test current, 90Ω max zener impedance at 2mA, 0.1µA max reverse leakage at 25.2V, and SOT-363 package. It provides precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the BZX84C36S-7-F datasheet, BZX84C36S-7-F pinout, BZX84C36S-7-F application, or BZX84C36S-7-F equivalent, key selection criteria include zener voltage tolerance (±5.6%), thermal resistance (625°C/W), ultra-small footprint for space-constrained PCBs, and RoHS-compliant matte tin plating.
Technical Context
This dual-element Zener diode integrates two independent 36V zener junctions in a single SOT-363 package, sharing no internal connection-each anode/cathode pair operates as a discrete regulator. It uses planar die construction for stable breakdown characteristics and low noise performance.
Rated for -65°C to +150°C operation, it delivers 200mW total power dissipation with derating above 25°C ambient per Figure 1. Its 90Ω dynamic impedance at 2mA and <0.1µA IR at VR = 25.2V support tight voltage reference stability in low-current bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Nom/Min/Max) | 36V / 34V / 38V - defines regulation band for 25.2–37.4V operating range under load |
| Test Current (IZT) | 2mA - standard bias point for specifying VZ and ZZT; enables low-quiescent-current reference design |
| Zener Impedance (ZZT) | 90Ω max @ 2mA - limits output voltage variation under changing load current |
| Reverse Leakage (IR) | 0.1µA max @ 25.2V - ensures minimal error current in high-impedance reference dividers |
| Power Dissipation | 200mW - sets maximum continuous DC power handling on FR4 board with recommended pad layout |
| Thermal Resistance (RθJA) | 625°C/W - determines junction temperature rise; requires thermal-aware layout for sustained operation |
| Operating Temperature | -65°C to +150°C - supports industrial and automotive under-hood applications without derating |
Pinout & Package
SOT-363 (SC-70-6) package: ultra-small surface-mount outline with six terminals, molded plastic case rated UL 94V-0, moisture sensitivity level 1.

| 2 (C1) | Cathode of Diode 1 | Connected to cathode of first Zener element; ties to regulated node |
| 3 (A1) | Anode of Diode 1 | Connected to anode of first Zener element; ties to input/reference rail |
| 4 (A2) | Anode of Diode 2 | Independent anode for second Zener; enables dual-rail or redundancy use |
| 5 (C2) | Cathode of Diode 2 | Independent cathode for second Zener; isolated from C1 electrically |
| 6 (NC) | No Connect | Unbonded terminal; must remain unconnected per mechanical drawing |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Zener elements | Two isolated 36V regulators in one SOT-363 footprint-reduces board area vs. discrete solutions |
| Planar die construction | Ensures repeatable breakdown voltage and low noise across production lots |
| Lead-free & RoHS compliant | Matte tin finish over Alloy 42 leadframe meets global environmental compliance requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5259BS-7-F | Single 36V Zener, SOT-363, 200mW, 100Ω ZZT @ 2mA, 0.1µA IR @ 25.2V | Single-element only; lacks dual-diode integration | Select when only one reference/clamp is needed and board space permits separate placement |
| BZX84C36LT1G | Single 36V Zener, SOT-23, 350mW, 90Ω ZZT @ 5mA, 0.1µA IR @ 25.2V | Higher power rating but larger SOT-23 footprint; different test current | Select when higher power margin is required and SOT-23 layout is already established |
Compared with MMBZ5259BS-7-F and BZX84C36LT1G, BZX84C36S-7-F uniquely offers dual 36V Zeners in SOT-363-enabling redundancy, dual-rail referencing, or space savings where two independent clamps are needed without doubling footprint.

FAQ
What is the maximum power dissipation for BZX84C36S-7-F?
The absolute maximum power dissipation is 200mW at 25°C ambient temperature on a standard FR4 PCB with the recommended pad layout. Power must be linearly derated above 25°C at 0.32mW/°C, reaching zero at 125°C ambient, per the derating curve in DS30108 Rev. 17–2.
How are the two Zener diodes configured inside the SOT-363 package?
The two Zener diodes are fully independent: Pin 2 (C1) and Pin 3 (A1) form Diode 1; Pin 4 (A2) and Pin 5 (C2) form Diode 2. Pins 1 and 6 are unconnected. No internal connection exists between the two elements-each operates as a standalone device.
Is BZX84C36S-7-F suitable for use as a voltage reference in precision analog circuits?
Yes-it delivers 36V regulation with ±5.6% tolerance (34–38V), 90Ω dynamic impedance, and <0.1µA leakage at 25.2V, making it appropriate for moderate-precision references where temperature drift (±0.05%/°C typical) and noise are acceptable. For high-precision needs, consider bandgap references instead.
What does the "-7-F" suffix indicate in the part number?
The "-7-F" suffix denotes tape-and-reel packaging: 3000 units per reel, with "7" indicating SOT-363 carrier tape format and "F" signifying lead-free/RoHS-compliant finish. This matches Diodes Incorporated's standard ordering convention per DS30108 page 3.
