BZT52C18-HE3-08 Description

Short technical summary and product information.

The BZT52C18-HE3-08 is a small signal Zener diode from Vishay, part of the BZT52 series. It provides a nominal Zener voltage of 18V with a tolerance of ±5%.

 

With a maximum power dissipation of 410mW (500mW on FR-4 board per datasheet), it is suitable for low-power voltage regulation and protection circuits. The reverse leakage current is 100nA at 14V. The maximum impedance (Zzt) is 18Ω at a test current of 5mA.

 

The device is housed in a SOD-123 surface mount package, weighing 10.6mg. It is rated for an operating temperature range of -55°C to 150°C. The package is MSL level 1 and RoHS compliant. The AEC-Q101 qualified version (HE3 suffix) ensures suitability for automotive applications.

 

The BZT52C18-HE3-08 features ESD capability of >8kV (HBM) and >800V (MM) per AEC-Q101, providing robust protection. It is supplied in tape and reel packaging with 3000 units per reel.
