Vishay BZX84C4V7-E3-08 is a 4.7 V small signal Zener diode packaged in a compact 3-pin SOT-23 surface mount case, rated for 300 mW maximum power dissipation. This diode is engineered for use in various electronic circuits requiring stable voltage regulation, clamping, and reference applications.
The diode operates reliably within ambient temperatures ranging from -65°C to 150°C, making it suitable for use in demanding industrial and automotive electronic systems, although it does not meet specific automotive standards. Its nominal Zener voltage is 4.7 V with a ±5% tolerance, delivering precise voltage stabilization. The maximum reverse leakage current of 3 μA ensures minimal power loss when reverse biased.
The small surface mount form factor (SOT-23) allows for high-density PCB designs typical in compact electronic devices, communications equipment, instrumentation, and power supplies. The diode’s test current is rated at 5 mA with a maximum Zener impedance of 80 Ω, supporting stable operation under controlled current.
Common industrial use cases include voltage regulation in low-power circuits, protection against voltage spikes, and reference voltage sources in measurement and control systems. The BZX84 series is trusted in electronics manufacturing for its reliability, compact size, and consistent electrical performance.
The diode features a 3-pin SOT-23 surface mount package for compact installations. Maximum power dissipation of 300 mW ensures durability in small power events. Operating temperature range from -65°C to 150°C suits industrial and commercial applications.
Precise voltage regulation with nominal 4.7 V Zener voltage ±5% tolerance. Minimum reverse leakage current maximizes energy efficiency in circuits. Stable voltage performance ensured by a low voltage temperature coefficient.
The Vishay BZX84C4V7-E3-08 diode is widely used in electronic component assemblies, instrumentation, power supplies, and other commercial and industrial applications requiring robust voltage regulation.
