onsemi BZX84C5V6_S00Z

Overview

BZX84C5V6_S00Z from ON Semiconductor is a 5.6 V ±5% tolerance Zener diode in SOT-23 package, rated for 250 mW power dissipation at 25°C ambient, with 10 Ω dynamic impedance at 20 mA test current and 1 µA maximum reverse leakage at 2.0 V. It provides precise voltage regulation in low-power biasing and reference circuits.

For engineers reviewing the BZX84C5V6_S00Z datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (465°C/W), junction temperature range (–55°C to +150°C), and low-capacitance operation (200 pF at 0 V) for stable DC reference performance.

Technical Context

This device operates as a two-terminal voltage reference, conducting in reverse breakdown when cathode-to-anode voltage exceeds its nominal 5.6 V Zener voltage. Its design supports stable regulation across –55°C to +150°C junction temperature, with specified dynamic impedance (10 Ω at 20 mA) and temperature coefficient (–2.0 mV/°C at 5 mA).

The BZX84C5V6_S00Z is optimized for surface-mount applications on FR-4 PCBs (76.2 mm × 114.3 mm), with thermal characteristics defined by junction-to-ambient (465°C/W) and junction-to-lead (220°C/W) resistances - critical for power derating in compact layouts.

FAQ

What is the nominal Zener voltage and tolerance of the BZX84C5V6_S00Z?

The BZX84C5V6_S00Z has a nominal Zener voltage of 5.6 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 5.2 V and 6.0 V when tested at 5 mA. This tolerance is confirmed in the Electrical Characteristics table of the official ON Semiconductor datasheet Rev. 1.10. The BZX84C5V6_S00Z maintains this specification across its full operating temperature range.

What is the maximum power dissipation rating for the BZX84C5V6_S00Z?

The BZX84C5V6_S00Z is rated for 250 mW power dissipation at an ambient temperature of 25°C when mounted on a standard FR-4 PCB (76.2 mm × 114.3 mm). Derating is required above 25°C per the junction-to-ambient thermal resistance of 465°C/W. This rating applies to continuous DC operation - pulsed conditions require consultation with ON Semiconductor per Absolute Maximum Ratings note 2. The BZX84C5V6_S00Z must not exceed this limit to ensure reliability.

What is the dynamic impedance of the BZX84C5V6_S00Z and why does it matter?

The BZX84C5V6_S00Z exhibits a maximum dynamic impedance (Z_Z) of 10 Ω at 20 mA Zener current, as specified in the Electrical Characteristics table. This low value indicates minimal change in output voltage under varying load current - critical for maintaining regulation accuracy in reference and feedback applications. A lower Z_Z directly improves line and load regulation performance. The BZX84C5V6_S00Z achieves this while retaining ±5% voltage tolerance and SOT-23 compatibility.

Does the BZX84C5V6_S00Z have a specified temperature coefficient?

Yes, the BZX84C5V6_S00Z has a temperature coefficient of –2.0 mV/°C at 5.0 mA Zener current, as listed in the "DVZ / Dt at 5.0 mA" column of the datasheet. This negative coefficient means its Zener voltage decreases slightly as temperature increases - a key parameter for designing temperature-stable references or compensating circuits. The BZX84C5V6_S00Z's coefficient is confirmed across the –55°C to +150°C junction temperature range and is essential for analog precision applications.

What is the reverse leakage current specification for the BZX84C5V6_S00Z?

The BZX84C5V6_S00Z specifies a maximum reverse leakage current (I_R) of 1 µA at a reverse voltage (V_R) of 2.0 V, per the Electrical Characteristics table. This low leakage ensures minimal parasitic current draw in high-impedance bias networks and reference dividers. It also contributes to low quiescent power consumption in always-on sensor circuits. The BZX84C5V6_S00Z meets this spec across its full storage temperature range (–55°C to +150°C), supporting reliable operation in harsh environments.
