Product details
Overview
BZX84C5V6ET1G from onsemi is a 5.6 V, 250 mW surface-mount Zener diode in SOT-23 package, designed for precision voltage regulation and reference applications with ±0.4 V tolerance at 5 mA test current, 40 Ω dynamic impedance, and −2 mV/°C temperature coefficient. It operates reliably in space-constrained portable electronics requiring stable low-voltage clamping.
For engineers reviewing the BZX84C5V6ET1G datasheet, pinout, applications, or equivalent options, key selection criteria include nominal Zener voltage (5.6 V), power dissipation (250 mW on FR-5 board), thermal resistance (500 °C/W), ESD rating (>16 kV HBM), and SOT-23 footprint compatibility with automated assembly.
Technical Context
This Zener diode provides stable reverse-biased breakdown at 5.6 V with tight tolerance (5.2–6.0 V) and low dynamic impedance (40 Ω @ 5 mA), enabling accurate voltage referencing in low-power analog circuits. Its −2 mV/°C temperature coefficient minimizes drift across −65 °C to +150 °C operating range.
The device features a cathode-anode configuration with Pin 1 = Anode, Pin 2 = No Connection, Pin 3 = Cathode, and is optimized for high-density PCB layouts using Pb-free SOT-23 (Case 318) packaging. It meets Class 3 ESD immunity (>16 kV HBM) and supports peak pulse power of 225 W (8 × 20 µs).

FAQ
What is the nominal Zener voltage and tolerance of BZX84C5V6ET1G?
The BZX84C5V6ET1G has a nominal Zener voltage of 5.6 V with a guaranteed range of 5.2 V to 6.0 V at 5 mA test current (IZT). This ±0.4 V tolerance ensures consistent clamping behavior across production lots and supports designs requiring tight voltage reference stability in 5 V system rails.
What is the maximum power dissipation rating for BZX84C5V6ET1G on standard PCB material?
The BZX84C5V6ET1G is rated for 250 mW total power dissipation on FR-5 board at 25 °C ambient, derating linearly above that temperature at 2.0 mW/°C. This rating reflects real-world thermal performance on common rigid PCB substrates and defines safe continuous operating limits without heatsinking.
Does BZX84C5V6ET1G have automotive qualification?
The BZX84C5V6ET1G is not explicitly AEC-Q101 qualified per its datasheet; however, the SZ-prefix variant (SZBZX84C5V6ET1G) is AEC-Q101 qualified and PPAP capable. For automotive applications requiring formal qualification, the SZ variant must be selected - BZX84C5V6ET1G is intended for industrial and consumer use.
What is the pin configuration and polarity marking for BZX84C5V6ET1G?
The BZX84C5V6ET1G uses a 3-pin SOT-23 package with Pin 1 = Anode, Pin 2 = No Connection (unbonded), Pin 3 = Cathode. The cathode is marked by a polarity band on the package body, and correct orientation is critical for reverse-bias operation in voltage regulation circuits.
What is the Zener impedance and why does it matter for BZX84C5V6ET1G?
The BZX84C5V6ET1G exhibits a maximum Zener impedance (ZZT) of 40 Ω at 5 mA test current. This low dynamic impedance ensures minimal voltage variation under changing load conditions - critical for maintaining reference accuracy in precision analog circuits and stable clamping during fast transients.
