Product details
Overview
BZT585B5V6T-7 from Diodes Incorporated is a precision surface-mount Zener diode with nominal 5.6 V breakdown voltage, ±2.0% tolerance, 40 Ω dynamic impedance at 5 mA test current, and 350 mW power dissipation in SOD523 package-used for voltage regulation and reference in low-power analog circuits, sensor biasing, and overvoltage protection.
For engineers reviewing the BZT585B5V6T-7 datasheet, BZT585B5V6T-7 pinout, BZT585B5V6T-7 application, or BZT585B5V6T-7 equivalent, key selection criteria include Zener voltage accuracy, low thermal resistance (357 °C/W), tight temperature coefficient (+1.0 mV/°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. It features a flat-lead SOD523 package optimized for low profile (max 0.35 mm height) and high thermal efficiency on FR-4 PCBs.
Its 1.0 mV/°C positive temperature coefficient ensures predictable voltage drift above 25°C, while 275 pF capacitance at 0 V and 1 µA maximum reverse leakage at 1 V support use in low-noise, high-frequency reference paths and ESD-tolerant signal conditioning stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.49–5.71 V range at 5 mA - enables precise 5.5 V rail clamping or reference generation |
| Zener Impedance (ZZT) | 40 Ω at IZT = 5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (PD) | 350 mW - supports continuous operation up to 125°C ambient with standard pad layout |
| Temperature Coefficient (TC) | +1.0 mV/°C - provides predictable, linear voltage increase with junction temperature rise |
| Reverse Leakage (IR) | 1 µA max at VR = 1 V - minimizes quiescent current in battery-powered voltage monitor circuits |
| Total Capacitance (CT) | 275 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in precision analog front-ends |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - allows use as low-drop clamp in bidirectional protection schemes |

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 (Diodes Inc.) | Same 5.6 V nominal, but ±5% tolerance and 100 Ω ZZT; SOT-323 package (larger, 2.1 × 1.3 mm) | Higher impedance and looser tolerance limit use in precision references; better suited for general-purpose clamping | Select when cost priority outweighs voltage stability, and board space permits SOT-323 |
| BZX84-C5V6 (Nexperia) | 5.6 V, ±5% tolerance, 60 Ω ZZT, SOT-23 package; not AEC-Q101 qualified | Lacks automotive qualification and tighter TC (+2.5 mV/°C); higher capacitance (450 pF) | Choose for consumer electronics where AEC-Q101 is unnecessary and higher CT is acceptable |
Compared with MMBZ5232BS-7-F and BZX84-C5V6, BZT585B5V6T-7 delivers superior voltage accuracy, lower dynamic impedance, and automotive-grade reliability in the smallest footprint-making it optimal for space-constrained, high-stability applications.

FAQ
What is the maximum continuous reverse power dissipation for BZT585B5V6T-7?
The device is rated for 350 mW continuous power dissipation at 25°C ambient when mounted on an FR-4 PCB with Diodes Incorporated's recommended pad layout (AP02001). Derating begins at 2.8 mW/°C above 25°C, reaching zero dissipation at 150°C ambient per the published derating curve.
Is BZT585B5V6T-7 suitable for automotive applications?
Yes-it is fully qualified to AEC-Q101 standards, with operating temperature range from -65°C to +150°C, halogen- and antimony-free "Green" construction, and robust moisture sensitivity level 1 handling. It is widely deployed in engine control units, body electronics, and ADAS sensor modules.
How does the +1.0 mV/°C temperature coefficient affect circuit design?
This positive coefficient means the Zener voltage increases linearly with junction temperature-by 1.0 mV per degree Celsius rise above 25°C. Designers must account for this drift in high-accuracy references; for example, a 50°C rise adds +50 mV to nominal 5.6 V, yielding 5.65 V at 75°C junction temperature.
Can BZT585B5V6T-7 be used in bidirectional ESD protection configurations?
Yes-its 0.9 V forward voltage at 10 mA and symmetrical SOD523 package allow pairing two units anode-to-anode or cathode-to-cathode to create low-capacitance, bidirectional TVS clamps. The 275 pF capacitance and 1 µA leakage preserve signal integrity on high-speed lines like I²C or CAN FD.
