Product details
Overview
BZX84C5V6T-7-F from Diodes Incorporated is a 5.6 V, 150 mW surface-mount Zener diode in SOT-523 package, with nominal zener voltage tolerance ±7.1%, dynamic impedance of 40 Ω at 5 mA test current, and reverse leakage ≤1.0 µA at 2.0 V, used for precision voltage regulation and reference in low-power sensor biasing and power supply feedback networks.
For engineers reviewing the BZX84C5V6T-7-F datasheet, BZX84C5V6T-7-F pinout, BZX84C5V6T-7-F application, or BZX84C5V6T-7-F equivalent, key selection criteria include zener voltage accuracy at IZT = 5 mA, thermal resistance (833 °C/W), low leakage at VR = 2.0 V, and SOT-523 footprint compatibility in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and input conditions. It uses planar die construction for consistent parametric performance and is rated for continuous power dissipation of 150 mW at 25 °C ambient, derating linearly above 25 °C per the published curve.
Its temperature coefficient of zener voltage is −2.0 to +2.5 mV/°C at IZT = 5 mA, enabling predictable drift behavior in temperature-sensitive references. The device exhibits typical total capacitance of ~15 pF at nominal 5.6 V, supporting moderate-frequency noise filtering without compromising regulation stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V range at IZT = 5 mA - defines regulated output voltage tolerance in shunt regulator designs |
| Power Dissipation (PD) | 150 mW maximum at TA = 25 °C - sets upper limit for continuous power handling on standard FR-4 board |
| Zener Impedance (ZZT) | 40 Ω at IZT = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Leakage (IR) | ≤1.0 µA at VR = 2.0 V - ensures minimal quiescent current draw in battery-powered standby circuits |
| Thermal Resistance (RθJA) | 833 °C/W - indicates junction-to-ambient temperature rise per milliwatt, critical for thermal design margin |
| Operating Temperature | −65 to +150 °C - supports industrial and automotive under-hood applications with wide ambient swings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | Zener voltage 5.1 V (±5%), 200 mW rating, SOT-323 package, RθJA = 500 °C/W | Higher power handling but larger footprint; tighter VZ tolerance improves reference accuracy | Select when higher power margin or improved voltage tolerance is required and board space permits SOT-323 |
| 1SMB5919BT3G | Zener voltage 5.6 V (±5%), 3 W rating, DO-214AA package, RθJA = 100 °C/W | Designed for high-energy surge suppression, not precision regulation; unsuitable for low-current references | Choose only for primary overvoltage protection in AC/DC front-ends where power dissipation exceeds 150 mW |
Compared with MMBZ5232BS-7-F and 1SMB5919BT3G, BZX84C5V6T-7-F offers optimal balance of ultra-compact size, adequate regulation precision, and thermal performance for space-limited, low-power analog subsystems-whereas alternatives trade size for power or accuracy.

FAQ
What is the maximum reverse current at 2.0 V for BZX84C5V6T-7-F?
The maximum reverse leakage current is 1.0 µA at VR = 2.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains ≤2.0 µA across the full operating temperature range (−65 to +150 °C), ensuring minimal standby power loss in always-on circuits.
Can BZX84C5V6T-7-F be used in place of a 5.1 V Zener diode?
No-it is not a direct substitute due to its 5.6 V nominal zener voltage (5.2–6.0 V range). Using it in a 5.1 V reference design would cause over-regulation, potentially damaging downstream circuitry or violating voltage thresholds. Select BZX84C5V1T-7-F for 5.1 V applications.
Is the SOT-523 package compatible with standard reflow soldering processes?
Yes-the SOT-523 package is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity, with matte tin plating meeting MIL-STD-202 Method 208 solderability requirements. Recommended peak temperature is 260 °C for ≤10 seconds, matching standard Pb-free profile settings.
Does BZX84C5V6T-7-F have a specified capacitance value?
While no single capacitance value is guaranteed in the datasheet, Figure 4 shows typical total capacitance of ~15 pF at VR = 0 V for 5.6 V nominal devices. This enables effective high-frequency noise suppression without loading sensitive analog nodes, especially in sensor interface applications.
