Product details
Overview
BZT585B5V6TQ from Diodes Incorporated is a precision Zener diode with 5.6 V nominal breakdown voltage (±2.0% tolerance), 40 Ω dynamic impedance at 5 mA test current, and 350 mW power dissipation in SOD523 package. It operates from −65 °C to +150 °C, features AEC-Q101 qualification, and serves as a stable voltage reference in automotive power supply monitoring circuits.
For engineers reviewing the BZT585B5V6TQ datasheet, BZT585B5V6TQ pinout, BZT585B5V6TQ application, or BZT585B5V6TQ equivalent, key selection criteria include Zener voltage accuracy, low thermal coefficient (+1.0 mV/°C), low capacitance (275 pF), and automotive-grade reliability under transient load conditions.
Technical Context
This Zener diode uses silicon planar construction with controlled avalanche breakdown for precise voltage regulation. Its ±2.0% VZ tolerance and +1.0 mV/°C temperature coefficient ensure stable reference performance across automotive ambient ranges.
The device delivers 350 mW maximum power dissipation on FR-4 PCB with standard pad layout and exhibits 1 µA reverse leakage at 2 V, enabling low-power biasing and sensing applications where minimal quiescent current is critical.
Key Specifications

| 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 in compact SOD523 footprint without forced cooling |
| Temperature Coefficient | +1.0 mV/°C at 5 mA - provides predictable, low-drift behavior over −65 °C to +150 °C |
| Reverse Leakage (IR) | 1 µA at VR = 2 V - minimizes standby current in battery-backed or low-power systems |
| Capacitance (CT) | 275 pF at f = 1 MHz, VR = 0 V - suitable for DC/low-frequency regulation, not RF bypass |
| Package | SOD523 - 1.2 mm × 0.8 mm × 0.6 mm low-profile surface-mount package for space-constrained PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5232BT1G | 5.6 V nominal, ±5% tolerance, 150 Ω ZZT, SOD-123 package (2.7 mm × 1.6 mm) | Larger footprint, higher impedance, wider VZ spread - less suitable for tight-tolerance automotive monitoring | Select when cost sensitivity outweighs precision and board space constraints |
| BZX84-C5V6 | 5.6 V nominal, ±5% tolerance, 60 Ω ZZT, SOT-23 package (3.0 mm × 1.4 mm) | Higher thermal resistance, no AEC-Q101 qualification - limited to commercial-grade applications | Choose only for non-automotive, non-safety-critical consumer electronics |
Compared with MMSZ5232BT1G and BZX84-C5V6, BZT585B5V6TQ offers tighter voltage tolerance, lower dynamic impedance, smaller SOD523 footprint, and AEC-Q101 qualification-making it the preferred choice for space-constrained, high-reliability automotive and industrial voltage reference designs.

FAQ
What is the maximum reverse voltage this Zener can sustain before breakdown?
The BZT585B5V6TQ has a nominal Zener voltage of 5.6 V with a guaranteed range of 5.49 V to 5.71 V at 5 mA test current. Breakdown occurs within this range under reverse bias; operation above 5.71 V risks exceeding specified power dissipation unless current is strictly limited by external series resistance.
Is this part suitable for use in high-humidity or under-hood automotive environments?
Yes - the device is packaged in UL 94V-0 molded plastic with moisture sensitivity level 1 (per J-STD-020), and is manufactured in IATF16949:2016-certified facilities. Its matte tin terminals and halogen-free "Green" compound provide corrosion resistance essential for under-hood deployment.
How does the +1.0 mV/°C temperature coefficient affect long-term reference stability?
The positive temperature coefficient means VZ increases linearly with junction temperature. Over −40 °C to +125 °C, total drift is approximately ±165 mV - acceptable for non-precision biasing but requires compensation in metrology-grade references. For most automotive monitoring, this drift remains within system error budgets.
Can this Zener be used in parallel to increase power handling?
No - Zener diodes exhibit manufacturing variations in VZ and dynamic impedance. Parallel connection causes current hogging, thermal runaway, and premature failure. To increase power capability, use a single higher-rated Zener or add an external series pass transistor with proper thermal design.
