Product details
Overview
BZX585B6V2 from Taiwan Semiconductor is a surface-mount Zener diode with nominal zener voltage 6.2 V ±2%, 200 mW power dissipation, 141 Ω dynamic impedance at 10 mA test current, and SOD-523F package. It provides precise voltage regulation in low-power biasing and reference circuits for portable electronics and sensor signal conditioning.
For engineers reviewing the BZX585B6V2 datasheet, BZX585B6V2 pinout, BZX585B6V2 application, or BZX585B6V2 equivalent, key selection criteria include zener tolerance (±2%), thermal resistance (680 °C/W), reverse leakage (<5 μA at 4.5 V), temperature coefficient (+0.4 mV/°C), and MSL-1 moisture sensitivity rating.
Technical Context
The BZX585B6V2 operates as a two-terminal voltage reference device, conducting in reverse breakdown at precisely controlled 6.2 V under 10 mA test current. Its 2% voltage tolerance and +0.4 mV/°C temperature coefficient enable stable DC biasing across industrial temperature ranges (−65 °C to +150 °C).
Designed for space-constrained PCB layouts, the SOD-523F package delivers high thermal resistance (680 °C/W) and supports reflow soldering up to 260 °C for 10 seconds. Reverse leakage remains below 5 μA at 4.5 V, ensuring minimal quiescent current draw in battery-powered systems.

FAQ
What is the zener voltage tolerance of the BZX585B6V2?
The BZX585B6V2 has a zener voltage tolerance of ±2% at 10 mA test current, meaning its nominal 6.2 V breakdown occurs between 6.08 V and 6.32 V under specified conditions. This tight tolerance supports precision analog reference design without calibration. The BZX585B6V2 datasheet confirms this value in the Electrical Characteristics table under "VZ @ IZT".
What is the maximum power dissipation for the BZX585B6V2?
The BZX585B6V2 has a maximum power dissipation of 200 mW at 25 °C ambient temperature. Derating begins above 25 °C per the thermal curve in the datasheet, with full derating to zero at 150 °C junction temperature. This limit directly constrains usable current in BZX585B6V2-based regulator circuits.
Is the BZX585B6V2 compatible with lead-free reflow soldering processes?
Yes, the BZX585B6V2 is qualified for high-temperature soldering at 260 °C for 10 seconds, fully supporting standard lead-free reflow profiles. Its SOD-523F package and halogen-free epoxy meet JEDEC J-STD-020 requirements. This specification is explicitly stated in the Mechanical Data section of the BZX585B6V2 datasheet.
What is the reverse leakage current of the BZX585B6V2 at 4.5 V?
The BZX585B6V2 exhibits a maximum reverse leakage current of 5 μA at 4.5 V, as specified in the Electrical Characteristics table. This low leakage supports energy-efficient operation in always-on sensor nodes and battery-backed systems where quiescent current must be minimized. The BZX585B6V2 maintains this performance across its rated storage temperature range.
Does the BZX585B6V2 have a defined temperature coefficient?
Yes, the BZX585B6V2 has a typical temperature coefficient of +0.4 mV/°C at 10 mA test current, indicating a positive drift in zener voltage with rising temperature. This value is critical for predicting regulation accuracy across operating temperatures and is documented in the BZX585B6V2 datasheet under "Temperature Coefficient Tc @ IZT".
